+ Dynamic DMA mapping Guide
+ =========================
+
+ David S. Miller <davem@redhat.com>
+ Richard Henderson <rth@cygnus.com>
+ Jakub Jelinek <jakub@redhat.com>
+
+This is a guide to device driver writers on how to use the DMA API
+with example pseudo-code. For a concise description of the API, see
+DMA-API.txt.
+
+Most of the 64bit platforms have special hardware that translates bus
+addresses (DMA addresses) into physical addresses. This is similar to
+how page tables and/or a TLB translates virtual addresses to physical
+addresses on a CPU. This is needed so that e.g. PCI devices can
+access with a Single Address Cycle (32bit DMA address) any page in the
+64bit physical address space. Previously in Linux those 64bit
+platforms had to set artificial limits on the maximum RAM size in the
+system, so that the virt_to_bus() static scheme works (the DMA address
+translation tables were simply filled on bootup to map each bus
+address to the physical page __pa(bus_to_virt())).
+
+So that Linux can use the dynamic DMA mapping, it needs some help from the
+drivers, namely it has to take into account that DMA addresses should be
+mapped only for the time they are actually used and unmapped after the DMA
+transfer.
+
+The following API will work of course even on platforms where no such
+hardware exists.
+
+Note that the DMA API works with any bus independent of the underlying
+microprocessor architecture. You should use the DMA API rather than
+the bus specific DMA API (e.g. pci_dma_*).
+
+First of all, you should make sure
+
+#include <linux/dma-mapping.h>
+
+is in your driver. This file will obtain for you the definition of the
+dma_addr_t (which can hold any valid DMA address for the platform)
+type which should be used everywhere you hold a DMA (bus) address
+returned from the DMA mapping functions.
+
+ What memory is DMA'able?
+
+The first piece of information you must know is what kernel memory can
+be used with the DMA mapping facilities. There has been an unwritten
+set of rules regarding this, and this text is an attempt to finally
+write them down.
+
+If you acquired your memory via the page allocator
+(i.e. __get_free_page*()) or the generic memory allocators
+(i.e. kmalloc() or kmem_cache_alloc()) then you may DMA to/from
+that memory using the addresses returned from those routines.
+
+This means specifically that you may _not_ use the memory/addresses
+returned from vmalloc() for DMA. It is possible to DMA to the
+_underlying_ memory mapped into a vmalloc() area, but this requires
+walking page tables to get the physical addresses, and then
+translating each of those pages back to a kernel address using
+something like __va(). [ EDIT: Update this when we integrate
+Gerd Knorr's generic code which does this. ]
+
+This rule also means that you may use neither kernel image addresses
+(items in data/text/bss segments), nor module image addresses, nor
+stack addresses for DMA. These could all be mapped somewhere entirely
+different than the rest of physical memory. Even if those classes of
+memory could physically work with DMA, you'd need to ensure the I/O
+buffers were cacheline-aligned. Without that, you'd see cacheline
+sharing problems (data corruption) on CPUs with DMA-incoherent caches.
+(The CPU could write to one word, DMA would write to a different one
+in the same cache line, and one of them could be overwritten.)
+
+Also, this means that you cannot take the return of a kmap()
+call and DMA to/from that. This is similar to vmalloc().
+
+What about block I/O and networking buffers? The block I/O and
+networking subsystems make sure that the buffers they use are valid
+for you to DMA from/to.
+
+ DMA addressing limitations
+
+Does your device have any DMA addressing limitations? For example, is
+your device only capable of driving the low order 24-bits of address?
+If so, you need to inform the kernel of this fact.
+
+By default, the kernel assumes that your device can address the full
+32-bits. For a 64-bit capable device, this needs to be increased.
+And for a device with limitations, as discussed in the previous
+paragraph, it needs to be decreased.
+
+Special note about PCI: PCI-X specification requires PCI-X devices to
+support 64-bit addressing (DAC) for all transactions. And at least
+one platform (SGI SN2) requires 64-bit consistent allocations to
+operate correctly when the IO bus is in PCI-X mode.
+
+For correct operation, you must interrogate the kernel in your device
+probe routine to see if the DMA controller on the machine can properly
+support the DMA addressing limitation your device has. It is good
+style to do this even if your device holds the default setting,
+because this shows that you did think about these issues wrt. your
+device.
+
+The query is performed via a call to dma_set_mask():
+
+ int dma_set_mask(struct device *dev, u64 mask);
+
+The query for consistent allocations is performed via a call to
+dma_set_coherent_mask():
+
+ int dma_set_coherent_mask(struct device *dev, u64 mask);
+
+Here, dev is a pointer to the device struct of your device, and mask
+is a bit mask describing which bits of an address your device
+supports. It returns zero if your card can perform DMA properly on
+the machine given the address mask you provided. In general, the
+device struct of your device is embedded in the bus specific device
+struct of your device. For example, a pointer to the device struct of
+your PCI device is pdev->dev (pdev is a pointer to the PCI device
+struct of your device).
+
+If it returns non-zero, your device cannot perform DMA properly on
+this platform, and attempting to do so will result in undefined
+behavior. You must either use a different mask, or not use DMA.
+
+This means that in the failure case, you have three options:
+
+1) Use another DMA mask, if possible (see below).
+2) Use some non-DMA mode for data transfer, if possible.
+3) Ignore this device and do not initialize it.
+
+It is recommended that your driver print a kernel KERN_WARNING message
+when you end up performing either #2 or #3. In this manner, if a user
+of your driver reports that performance is bad or that the device is not
+even detected, you can ask them for the kernel messages to find out
+exactly why.
+
+The standard 32-bit addressing device would do something like this:
+
+ if (dma_set_mask(dev, DMA_BIT_MASK(32))) {
+ printk(KERN_WARNING
+ "mydev: No suitable DMA available.\n");
+ goto ignore_this_device;
+ }
+
+Another common scenario is a 64-bit capable device. The approach here
+is to try for 64-bit addressing, but back down to a 32-bit mask that
+should not fail. The kernel may fail the 64-bit mask not because the
+platform is not capable of 64-bit addressing. Rather, it may fail in
+this case simply because 32-bit addressing is done more efficiently
+than 64-bit addressing. For example, Sparc64 PCI SAC addressing is
+more efficient than DAC addressing.
+
+Here is how you would handle a 64-bit capable device which can drive
+all 64-bits when accessing streaming DMA:
+
+ int using_dac;
+
+ if (!dma_set_mask(dev, DMA_BIT_MASK(64))) {
+ using_dac = 1;
+ } else if (!dma_set_mask(dev, DMA_BIT_MASK(32))) {
+ using_dac = 0;
+ } else {
+ printk(KERN_WARNING
+ "mydev: No suitable DMA available.\n");
+ goto ignore_this_device;
+ }
+
+If a card is capable of using 64-bit consistent allocations as well,
+the case would look like this:
+
+ int using_dac, consistent_using_dac;
+
+ if (!dma_set_mask(dev, DMA_BIT_MASK(64))) {
+ using_dac = 1;
+ consistent_using_dac = 1;
+ dma_set_coherent_mask(dev, DMA_BIT_MASK(64));
+ } else if (!dma_set_mask(dev, DMA_BIT_MASK(32))) {
+ using_dac = 0;
+ consistent_using_dac = 0;
+ dma_set_coherent_mask(dev, DMA_BIT_MASK(32));
+ } else {
+ printk(KERN_WARNING
+ "mydev: No suitable DMA available.\n");
+ goto ignore_this_device;
+ }
+
+dma_set_coherent_mask() will always be able to set the same or a
+smaller mask as dma_set_mask(). However for the rare case that a
+device driver only uses consistent allocations, one would have to
+check the return value from dma_set_coherent_mask().
+
+Finally, if your device can only drive the low 24-bits of
+address you might do something like:
+
+ if (dma_set_mask(dev, DMA_BIT_MASK(24))) {
+ printk(KERN_WARNING
+ "mydev: 24-bit DMA addressing not available.\n");
+ goto ignore_this_device;
+ }
+
+When dma_set_mask() is successful, and returns zero, the kernel saves
+away this mask you have provided. The kernel will use this
+information later when you make DMA mappings.
+
+There is a case which we are aware of at this time, which is worth
+mentioning in this documentation. If your device supports multiple
+functions (for example a sound card provides playback and record
+functions) and the various different functions have _different_
+DMA addressing limitations, you may wish to probe each mask and
+only provide the functionality which the machine can handle. It
+is important that the last call to dma_set_mask() be for the
+most specific mask.
+
+Here is pseudo-code showing how this might be done:
+
+ #define PLAYBACK_ADDRESS_BITS DMA_BIT_MASK(32)
+ #define RECORD_ADDRESS_BITS DMA_BIT_MASK(24)
+
+ struct my_sound_card *card;
+ struct device *dev;
+
+ ...
+ if (!dma_set_mask(dev, PLAYBACK_ADDRESS_BITS)) {
+ card->playback_enabled = 1;
+ } else {
+ card->playback_enabled = 0;
+ printk(KERN_WARNING "%s: Playback disabled due to DMA limitations.\n",
+ card->name);
+ }
+ if (!dma_set_mask(dev, RECORD_ADDRESS_BITS)) {
+ card->record_enabled = 1;
+ } else {
+ card->record_enabled = 0;
+ printk(KERN_WARNING "%s: Record disabled due to DMA limitations.\n",
+ card->name);
+ }
+
+A sound card was used as an example here because this genre of PCI
+devices seems to be littered with ISA chips given a PCI front end,
+and thus retaining the 16MB DMA addressing limitations of ISA.
+
+ Types of DMA mappings
+
+There are two types of DMA mappings:
+
+- Consistent DMA mappings which are usually mapped at driver
+ initialization, unmapped at the end and for which the hardware should
+ guarantee that the device and the CPU can access the data
+ in parallel and will see updates made by each other without any
+ explicit software flushing.
+
+ Think of "consistent" as "synchronous" or "coherent".
+
+ The current default is to return consistent memory in the low 32
+ bits of the bus space. However, for future compatibility you should
+ set the consistent mask even if this default is fine for your
+ driver.
+
+ Good examples of what to use consistent mappings for are:
+
+ - Network card DMA ring descriptors.
+ - SCSI adapter mailbox command data structures.
+ - Device firmware microcode executed out of
+ main memory.
+
+ The invariant these examples all require is that any CPU store
+ to memory is immediately visible to the device, and vice
+ versa. Consistent mappings guarantee this.
+
+ IMPORTANT: Consistent DMA memory does not preclude the usage of
+ proper memory barriers. The CPU may reorder stores to
+ consistent memory just as it may normal memory. Example:
+ if it is important for the device to see the first word
+ of a descriptor updated before the second, you must do
+ something like:
+
+ desc->word0 = address;
+ wmb();
+ desc->word1 = DESC_VALID;
+
+ in order to get correct behavior on all platforms.
+
+ Also, on some platforms your driver may need to flush CPU write
+ buffers in much the same way as it needs to flush write buffers
+ found in PCI bridges (such as by reading a register's value
+ after writing it).
+
+- Streaming DMA mappings which are usually mapped for one DMA
+ transfer, unmapped right after it (unless you use dma_sync_* below)
+ and for which hardware can optimize for sequential accesses.
+
+ This of "streaming" as "asynchronous" or "outside the coherency
+ domain".
+
+ Good examples of what to use streaming mappings for are:
+
+ - Networking buffers transmitted/received by a device.
+ - Filesystem buffers written/read by a SCSI device.
+
+ The interfaces for using this type of mapping were designed in
+ such a way that an implementation can make whatever performance
+ optimizations the hardware allows. To this end, when using
+ such mappings you must be explicit about what you want to happen.
+
+Neither type of DMA mapping has alignment restrictions that come from
+the underlying bus, although some devices may have such restrictions.
+Also, systems with caches that aren't DMA-coherent will work better
+when the underlying buffers don't share cache lines with other data.
+
+
+ Using Consistent DMA mappings.
+
+To allocate and map large (PAGE_SIZE or so) consistent DMA regions,
+you should do:
+
+ dma_addr_t dma_handle;
+
+ cpu_addr = dma_alloc_coherent(dev, size, &dma_handle, gfp);
+
+where device is a struct device *. This may be called in interrupt
+context with the GFP_ATOMIC flag.
+
+Size is the length of the region you want to allocate, in bytes.
+
+This routine will allocate RAM for that region, so it acts similarly to
+__get_free_pages (but takes size instead of a page order). If your
+driver needs regions sized smaller than a page, you may prefer using
+the dma_pool interface, described below.
+
+The consistent DMA mapping interfaces, for non-NULL dev, will by
+default return a DMA address which is 32-bit addressable. Even if the
+device indicates (via DMA mask) that it may address the upper 32-bits,
+consistent allocation will only return > 32-bit addresses for DMA if
+the consistent DMA mask has been explicitly changed via
+dma_set_coherent_mask(). This is true of the dma_pool interface as
+well.
+
+dma_alloc_coherent returns two values: the virtual address which you
+can use to access it from the CPU and dma_handle which you pass to the
+card.
+
+The cpu return address and the DMA bus master address are both
+guaranteed to be aligned to the smallest PAGE_SIZE order which
+is greater than or equal to the requested size. This invariant
+exists (for example) to guarantee that if you allocate a chunk
+which is smaller than or equal to 64 kilobytes, the extent of the
+buffer you receive will not cross a 64K boundary.
+
+To unmap and free such a DMA region, you call:
+
+ dma_free_coherent(dev, size, cpu_addr, dma_handle);
+
+where dev, size are the same as in the above call and cpu_addr and
+dma_handle are the values dma_alloc_coherent returned to you.
+This function may not be called in interrupt context.
+
+If your driver needs lots of smaller memory regions, you can write
+custom code to subdivide pages returned by dma_alloc_coherent,
+or you can use the dma_pool API to do that. A dma_pool is like
+a kmem_cache, but it uses dma_alloc_coherent not __get_free_pages.
+Also, it understands common hardware constraints for alignment,
+like queue heads needing to be aligned on N byte boundaries.
+
+Create a dma_pool like this:
+
+ struct dma_pool *pool;
+
+ pool = dma_pool_create(name, dev, size, align, alloc);
+
+The "name" is for diagnostics (like a kmem_cache name); dev and size
+are as above. The device's hardware alignment requirement for this
+type of data is "align" (which is expressed in bytes, and must be a
+power of two). If your device has no boundary crossing restrictions,
+pass 0 for alloc; passing 4096 says memory allocated from this pool
+must not cross 4KByte boundaries (but at that time it may be better to
+go for dma_alloc_coherent directly instead).
+
+Allocate memory from a dma pool like this:
+
+ cpu_addr = dma_pool_alloc(pool, flags, &dma_handle);
+
+flags are SLAB_KERNEL if blocking is permitted (not in_interrupt nor
+holding SMP locks), SLAB_ATOMIC otherwise. Like dma_alloc_coherent,
+this returns two values, cpu_addr and dma_handle.
+
+Free memory that was allocated from a dma_pool like this:
+
+ dma_pool_free(pool, cpu_addr, dma_handle);
+
+where pool is what you passed to dma_pool_alloc, and cpu_addr and
+dma_handle are the values dma_pool_alloc returned. This function
+may be called in interrupt context.
+
+Destroy a dma_pool by calling:
+
+ dma_pool_destroy(pool);
+
+Make sure you've called dma_pool_free for all memory allocated
+from a pool before you destroy the pool. This function may not
+be called in interrupt context.
+
+ DMA Direction
+
+The interfaces described in subsequent portions of this document
+take a DMA direction argument, which is an integer and takes on
+one of the following values:
+
+ DMA_BIDIRECTIONAL
+ DMA_TO_DEVICE
+ DMA_FROM_DEVICE
+ DMA_NONE
+
+One should provide the exact DMA direction if you know it.
+
+DMA_TO_DEVICE means "from main memory to the device"
+DMA_FROM_DEVICE means "from the device to main memory"
+It is the direction in which the data moves during the DMA
+transfer.
+
+You are _strongly_ encouraged to specify this as precisely
+as you possibly can.
+
+If you absolutely cannot know the direction of the DMA transfer,
+specify DMA_BIDIRECTIONAL. It means that the DMA can go in
+either direction. The platform guarantees that you may legally
+specify this, and that it will work, but this may be at the
+cost of performance for example.
+
+The value DMA_NONE is to be used for debugging. One can
+hold this in a data structure before you come to know the
+precise direction, and this will help catch cases where your
+direction tracking logic has failed to set things up properly.
+
+Another advantage of specifying this value precisely (outside of
+potential platform-specific optimizations of such) is for debugging.
+Some platforms actually have a write permission boolean which DMA
+mappings can be marked with, much like page protections in the user
+program address space. Such platforms can and do report errors in the
+kernel logs when the DMA controller hardware detects violation of the
+permission setting.
+
+Only streaming mappings specify a direction, consistent mappings
+implicitly have a direction attribute setting of
+DMA_BIDIRECTIONAL.
+
+The SCSI subsystem tells you the direction to use in the
+'sc_data_direction' member of the SCSI command your driver is
+working on.
+
+For Networking drivers, it's a rather simple affair. For transmit
+packets, map/unmap them with the DMA_TO_DEVICE direction
+specifier. For receive packets, just the opposite, map/unmap them
+with the DMA_FROM_DEVICE direction specifier.
+
+ Using Streaming DMA mappings
+
+The streaming DMA mapping routines can be called from interrupt
+context. There are two versions of each map/unmap, one which will
+map/unmap a single memory region, and one which will map/unmap a
+scatterlist.
+
+To map a single region, you do:
+
+ struct device *dev = &my_dev->dev;
+ dma_addr_t dma_handle;
+ void *addr = buffer->ptr;
+ size_t size = buffer->len;
+
+ dma_handle = dma_map_single(dev, addr, size, direction);
+
+and to unmap it:
+
+ dma_unmap_single(dev, dma_handle, size, direction);
+
+You should call dma_unmap_single when the DMA activity is finished, e.g.
+from the interrupt which told you that the DMA transfer is done.
+
+Using cpu pointers like this for single mappings has a disadvantage,
+you cannot reference HIGHMEM memory in this way. Thus, there is a
+map/unmap interface pair akin to dma_{map,unmap}_single. These
+interfaces deal with page/offset pairs instead of cpu pointers.
+Specifically:
+
+ struct device *dev = &my_dev->dev;
+ dma_addr_t dma_handle;
+ struct page *page = buffer->page;
+ unsigned long offset = buffer->offset;
+ size_t size = buffer->len;
+
+ dma_handle = dma_map_page(dev, page, offset, size, direction);
+
+ ...
+
+ dma_unmap_page(dev, dma_handle, size, direction);
+
+Here, "offset" means byte offset within the given page.
+
+With scatterlists, you map a region gathered from several regions by:
+
+ int i, count = dma_map_sg(dev, sglist, nents, direction);
+ struct scatterlist *sg;
+
+ for_each_sg(sglist, sg, count, i) {
+ hw_address[i] = sg_dma_address(sg);
+ hw_len[i] = sg_dma_len(sg);
+ }
+
+where nents is the number of entries in the sglist.
+
+The implementation is free to merge several consecutive sglist entries
+into one (e.g. if DMA mapping is done with PAGE_SIZE granularity, any
+consecutive sglist entries can be merged into one provided the first one
+ends and the second one starts on a page boundary - in fact this is a huge
+advantage for cards which either cannot do scatter-gather or have very
+limited number of scatter-gather entries) and returns the actual number
+of sg entries it mapped them to. On failure 0 is returned.
+
+Then you should loop count times (note: this can be less than nents times)
+and use sg_dma_address() and sg_dma_len() macros where you previously
+accessed sg->address and sg->length as shown above.
+
+To unmap a scatterlist, just call:
+
+ dma_unmap_sg(dev, sglist, nents, direction);
+
+Again, make sure DMA activity has already finished.
+
+PLEASE NOTE: The 'nents' argument to the dma_unmap_sg call must be
+ the _same_ one you passed into the dma_map_sg call,
+ it should _NOT_ be the 'count' value _returned_ from the
+ dma_map_sg call.
+
+Every dma_map_{single,sg} call should have its dma_unmap_{single,sg}
+counterpart, because the bus address space is a shared resource (although
+in some ports the mapping is per each BUS so less devices contend for the
+same bus address space) and you could render the machine unusable by eating
+all bus addresses.
+
+If you need to use the same streaming DMA region multiple times and touch
+the data in between the DMA transfers, the buffer needs to be synced
+properly in order for the cpu and device to see the most uptodate and
+correct copy of the DMA buffer.
+
+So, firstly, just map it with dma_map_{single,sg}, and after each DMA
+transfer call either:
+
+ dma_sync_single_for_cpu(dev, dma_handle, size, direction);
+
+or:
+
+ dma_sync_sg_for_cpu(dev, sglist, nents, direction);
+
+as appropriate.
+
+Then, if you wish to let the device get at the DMA area again,
+finish accessing the data with the cpu, and then before actually
+giving the buffer to the hardware call either:
+
+ dma_sync_single_for_device(dev, dma_handle, size, direction);
+
+or:
+
+ dma_sync_sg_for_device(dev, sglist, nents, direction);
+
+as appropriate.
+
+After the last DMA transfer call one of the DMA unmap routines
+dma_unmap_{single,sg}. If you don't touch the data from the first dma_map_*
+call till dma_unmap_*, then you don't have to call the dma_sync_*
+routines at all.
+
+Here is pseudo code which shows a situation in which you would need
+to use the dma_sync_*() interfaces.
+
+ my_card_setup_receive_buffer(struct my_card *cp, char *buffer, int len)
+ {
+ dma_addr_t mapping;
+
+ mapping = dma_map_single(cp->dev, buffer, len, DMA_FROM_DEVICE);
+
+ cp->rx_buf = buffer;
+ cp->rx_len = len;
+ cp->rx_dma = mapping;
+
+ give_rx_buf_to_card(cp);
+ }
+
+ ...
+
+ my_card_interrupt_handler(int irq, void *devid, struct pt_regs *regs)
+ {
+ struct my_card *cp = devid;
+
+ ...
+ if (read_card_status(cp) == RX_BUF_TRANSFERRED) {
+ struct my_card_header *hp;
+
+ /* Examine the header to see if we wish
+ * to accept the data. But synchronize
+ * the DMA transfer with the CPU first
+ * so that we see updated contents.
+ */
+ dma_sync_single_for_cpu(&cp->dev, cp->rx_dma,
+ cp->rx_len,
+ DMA_FROM_DEVICE);
+
+ /* Now it is safe to examine the buffer. */
+ hp = (struct my_card_header *) cp->rx_buf;
+ if (header_is_ok(hp)) {
+ dma_unmap_single(&cp->dev, cp->rx_dma, cp->rx_len,
+ DMA_FROM_DEVICE);
+ pass_to_upper_layers(cp->rx_buf);
+ make_and_setup_new_rx_buf(cp);
+ } else {
+ /* Just sync the buffer and give it back
+ * to the card.
+ */
+ dma_sync_single_for_device(&cp->dev,
+ cp->rx_dma,
+ cp->rx_len,
+ DMA_FROM_DEVICE);
+ give_rx_buf_to_card(cp);
+ }
+ }
+ }
+
+Drivers converted fully to this interface should not use virt_to_bus any
+longer, nor should they use bus_to_virt. Some drivers have to be changed a
+little bit, because there is no longer an equivalent to bus_to_virt in the
+dynamic DMA mapping scheme - you have to always store the DMA addresses
+returned by the dma_alloc_coherent, dma_pool_alloc, and dma_map_single
+calls (dma_map_sg stores them in the scatterlist itself if the platform
+supports dynamic DMA mapping in hardware) in your driver structures and/or
+in the card registers.
+
+All drivers should be using these interfaces with no exceptions. It
+is planned to completely remove virt_to_bus() and bus_to_virt() as
+they are entirely deprecated. Some ports already do not provide these
+as it is impossible to correctly support them.
+
+ Optimizing Unmap State Space Consumption
+
+On many platforms, dma_unmap_{single,page}() is simply a nop.
+Therefore, keeping track of the mapping address and length is a waste
+of space. Instead of filling your drivers up with ifdefs and the like
+to "work around" this (which would defeat the whole purpose of a
+portable API) the following facilities are provided.
+
+Actually, instead of describing the macros one by one, we'll
+transform some example code.
+
+1) Use DEFINE_DMA_UNMAP_{ADDR,LEN} in state saving structures.
+ Example, before:
+
+ struct ring_state {
+ struct sk_buff *skb;
+ dma_addr_t mapping;
+ __u32 len;
+ };
+
+ after:
+
+ struct ring_state {
+ struct sk_buff *skb;
+ DEFINE_DMA_UNMAP_ADDR(mapping);
+ DEFINE_DMA_UNMAP_LEN(len);
+ };
+
+2) Use dma_unmap_{addr,len}_set to set these values.
+ Example, before:
+
+ ringp->mapping = FOO;
+ ringp->len = BAR;
+
+ after:
+
+ dma_unmap_addr_set(ringp, mapping, FOO);
+ dma_unmap_len_set(ringp, len, BAR);
+
+3) Use dma_unmap_{addr,len} to access these values.
+ Example, before:
+
+ dma_unmap_single(dev, ringp->mapping, ringp->len,
+ DMA_FROM_DEVICE);
+
+ after:
+
+ dma_unmap_single(dev,
+ dma_unmap_addr(ringp, mapping),
+ dma_unmap_len(ringp, len),
+ DMA_FROM_DEVICE);
+
+It really should be self-explanatory. We treat the ADDR and LEN
+separately, because it is possible for an implementation to only
+need the address in order to perform the unmap operation.
+
+ Platform Issues
+
+If you are just writing drivers for Linux and do not maintain
+an architecture port for the kernel, you can safely skip down
+to "Closing".
+
+1) Struct scatterlist requirements.
+
+ Struct scatterlist must contain, at a minimum, the following
+ members:
+
+ struct page *page;
+ unsigned int offset;
+ unsigned int length;
+
+ The base address is specified by a "page+offset" pair.
+
+ Previous versions of struct scatterlist contained a "void *address"
+ field that was sometimes used instead of page+offset. As of Linux
+ 2.5., page+offset is always used, and the "address" field has been
+ deleted.
+
+2) More to come...
+
+ Handling Errors
+
+DMA address space is limited on some architectures and an allocation
+failure can be determined by:
+
+- checking if dma_alloc_coherent returns NULL or dma_map_sg returns 0
+
+- checking the returned dma_addr_t of dma_map_single and dma_map_page
+ by using dma_mapping_error():
+
+ dma_addr_t dma_handle;
+
+ dma_handle = dma_map_single(dev, addr, size, direction);
+ if (dma_mapping_error(dev, dma_handle)) {
+ /*
+ * reduce current DMA mapping usage,
+ * delay and try again later or
+ * reset driver.
+ */
+ }
+
+ Closing

+This document, and the API itself, would not be in it's current
+form without the feedback and suggestions from numerous individuals.

-them together, along with a lot of patches that have been plucked from
-the linux-kernel mailing list. This tree serves as a proving ground for
-new features and patches. Once a patch has proved its worth in -mm for
-a while Andrew or the subsystem maintainer pushes it on to Linus for
-inclusion in mainline.
-
-It is heavily encouraged that all new patches get tested in the -mm tree
-before they are sent to Linus for inclusion in the main kernel tree. Code
-which does not make an appearance in -mm before the opening of the merge
-window will prove hard to merge into the mainline.
-
-These kernels are not appropriate for use on systems that are supposed
-to be stable and they are more risky to run than any of the other
-branches.
-
-If you wish to help out with the kernel development process, please test
-and use these kernel releases and provide feedback to the linux-kernel
-mailing list if you have any problems, and if everything works properly.
-
-In addition to all the other experimental patches, these kernels usually
-also contain any changes in the mainline -git kernels available at the
-time of release.
-
-The -mm kernels are not released on a fixed schedule, but usually a few
--mm kernels are released in between each -rc kernel (1 to 3 is common).

Subsystem Specific kernel trees and patches
-------------------------------------------
-A number of the different kernel subsystem developers expose their
-development trees so that others can see what is happening in the
-different areas of the kernel. These trees are pulled into the -mm
-kernel releases as described above.
+The maintainers of the various kernel subsystems --- and also many
+kernel subsystem developers --- expose their current state of
+development in source repositories. That way, others can see what is
+happening in the different areas of the kernel. In areas where
+development is rapid, a developer may be asked to base his submissions
+onto such a subsystem kernel tree so that conflicts between the
+submission and other already ongoing work are avoided.
-Here is a list of some of the different kernel trees available:
- git trees:
- - Kbuild development tree, Sam Ravnborg <sam@ravnborg.org>
- git.kernel.org:/pub/scm/linux/kernel/git/sam/kbuild.git
+Most of these repositories are git trees, but there are also other SCMs
+in use, or patch queues being published as quilt series. Addresses of
+these subsystem repositories are listed in the MAINTAINERS file. Many
+of them can be browsed at http://git.kernel.org/.
- - ACPI development tree, Len Brown <len.brown@intel.com>
- git.kernel.org:/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6.git
+Before a proposed patch is committed to such a subsystem tree, it is
+subject to review which primarily happens on mailing lists (see the
+respective section below). For several kernel subsystems, this review
+process is tracked with the tool patchwork. Patchwork offers a web
+interface which shows patch postings, any comments on a patch or
+revisions to it, and maintainers can mark patches as under review,
+accepted, or rejected. Most of these patchwork sites are listed at
+http://patchwork.kernel.org/ or http://patchwork.ozlabs.org/.
- - Block development tree, Jens Axboe <jens.axboe@oracle.com>
- git.kernel.org:/pub/scm/linux/kernel/git/axboe/linux-2.6-block.git
+2.6.x -next kernel tree for integration tests
+---------------------------------------------
+Before updates from subsystem trees are merged into the mainline 2.6.x
+tree, they need to be integration-tested. For this purpose, a special
+testing repository exists into which virtually all subsystem trees are
+pulled on an almost daily basis:
+ http://git.kernel.org/?p=linux/kernel/git/sfr/linux-next.git
+ http://linux.f-seidel.de/linux-next/pmwiki/
- - DRM development tree, Dave Airlie <airlied@linux.ie>
- git.kernel.org:/pub/scm/linux/kernel/git/airlied/drm-2.6.git
+This way, the -next kernel gives a summary outlook onto what will be
+expected to go into the mainline kernel at the next merge period.
+Adventurous testers are very welcome to runtime-test the -next kernel.

- Dynamic DMA mapping
- ===================
-
- David S. Miller <davem@redhat.com>
- Richard Henderson <rth@cygnus.com>
- Jakub Jelinek <jakub@redhat.com>
-
-This document describes the DMA mapping system in terms of the pci_
-API. For a similar API that works for generic devices, see
-DMA-API.txt.
-
-Most of the 64bit platforms have special hardware that translates bus
-addresses (DMA addresses) into physical addresses. This is similar to
-how page tables and/or a TLB translates virtual addresses to physical
-addresses on a CPU. This is needed so that e.g. PCI devices can
-access with a Single Address Cycle (32bit DMA address) any page in the
-64bit physical address space. Previously in Linux those 64bit
-platforms had to set artificial limits on the maximum RAM size in the
-system, so that the virt_to_bus() static scheme works (the DMA address
-translation tables were simply filled on bootup to map each bus
-address to the physical page __pa(bus_to_virt())).
-
-So that Linux can use the dynamic DMA mapping, it needs some help from the
-drivers, namely it has to take into account that DMA addresses should be
-mapped only for the time they are actually used and unmapped after the DMA
-transfer.
-
-The following API will work of course even on platforms where no such
-hardware exists, see e.g. arch/x86/include/asm/pci.h for how it is implemented on
-top of the virt_to_bus interface.
-
-First of all, you should make sure
-
-#include <linux/pci.h>
-
-is in your driver. This file will obtain for you the definition of the
-dma_addr_t (which can hold any valid DMA address for the platform)
-type which should be used everywhere you hold a DMA (bus) address
-returned from the DMA mapping functions.
-
- What memory is DMA'able?
-
-The first piece of information you must know is what kernel memory can
-be used with the DMA mapping facilities. There has been an unwritten
-set of rules regarding this, and this text is an attempt to finally
-write them down.
-
-If you acquired your memory via the page allocator
-(i.e. __get_free_page*()) or the generic memory allocators
-(i.e. kmalloc() or kmem_cache_alloc()) then you may DMA to/from
-that memory using the addresses returned from those routines.
-
-This means specifically that you may _not_ use the memory/addresses
-returned from vmalloc() for DMA. It is possible to DMA to the
-_underlying_ memory mapped into a vmalloc() area, but this requires
-walking page tables to get the physical addresses, and then
-translating each of those pages back to a kernel address using
-something like __va(). [ EDIT: Update this when we integrate
-Gerd Knorr's generic code which does this. ]
-
-This rule also means that you may use neither kernel image addresses
-(items in data/text/bss segments), nor module image addresses, nor
-stack addresses for DMA. These could all be mapped somewhere entirely
-different than the rest of physical memory. Even if those classes of
-memory could physically work with DMA, you'd need to ensure the I/O
-buffers were cacheline-aligned. Without that, you'd see cacheline
-sharing problems (data corruption) on CPUs with DMA-incoherent caches.
-(The CPU could write to one word, DMA would write to a different one
-in the same cache line, and one of them could be overwritten.)
-
-Also, this means that you cannot take the return of a kmap()
-call and DMA to/from that. This is similar to vmalloc().
-
-What about block I/O and networking buffers? The block I/O and
-networking subsystems make sure that the buffers they use are valid
-for you to DMA from/to.
-
- DMA addressing limitations
-
-Does your device have any DMA addressing limitations? For example, is
-your device only capable of driving the low order 24-bits of address
-on the PCI bus for SAC DMA transfers? If so, you need to inform the
-PCI layer of this fact.
-
-By default, the kernel assumes that your device can address the full
-32-bits in a SAC cycle. For a 64-bit DAC capable device, this needs
-to be increased. And for a device with limitations, as discussed in
-the previous paragraph, it needs to be decreased.
-
-pci_alloc_consistent() by default will return 32-bit DMA addresses.
-PCI-X specification requires PCI-X devices to support 64-bit
-addressing (DAC) for all transactions. And at least one platform (SGI
-SN2) requires 64-bit consistent allocations to operate correctly when
-the IO bus is in PCI-X mode. Therefore, like with pci_set_dma_mask(),
-it's good practice to call pci_set_consistent_dma_mask() to set the
-appropriate mask even if your device only supports 32-bit DMA
-(default) and especially if it's a PCI-X device.
-
-For correct operation, you must interrogate the PCI layer in your
-device probe routine to see if the PCI controller on the machine can
-properly support the DMA addressing limitation your device has. It is
-good style to do this even if your device holds the default setting,
-because this shows that you did think about these issues wrt. your
-device.
-
-The query is performed via a call to pci_set_dma_mask():
-
- int pci_set_dma_mask(struct pci_dev *pdev, u64 device_mask);
-
-The query for consistent allocations is performed via a call to
-pci_set_consistent_dma_mask():
-
- int pci_set_consistent_dma_mask(struct pci_dev *pdev, u64 device_mask);
-
-Here, pdev is a pointer to the PCI device struct of your device, and
-device_mask is a bit mask describing which bits of a PCI address your
-device supports. It returns zero if your card can perform DMA
-properly on the machine given the address mask you provided.
-
-If it returns non-zero, your device cannot perform DMA properly on
-this platform, and attempting to do so will result in undefined
-behavior. You must either use a different mask, or not use DMA.
-
-This means that in the failure case, you have three options:
-
-1) Use another DMA mask, if possible (see below).
-2) Use some non-DMA mode for data transfer, if possible.
-3) Ignore this device and do not initialize it.
-
-It is recommended that your driver print a kernel KERN_WARNING message
-when you end up performing either #2 or #3. In this manner, if a user
-of your driver reports that performance is bad or that the device is not
-even detected, you can ask them for the kernel messages to find out
-exactly why.
-
-The standard 32-bit addressing PCI device would do something like
-this:
-
- if (pci_set_dma_mask(pdev, DMA_BIT_MASK(32))) {
- printk(KERN_WARNING
- "mydev: No suitable DMA available.\n");
- goto ignore_this_device;
- }
-
-Another common scenario is a 64-bit capable device. The approach
-here is to try for 64-bit DAC addressing, but back down to a
-32-bit mask should that fail. The PCI platform code may fail the
-64-bit mask not because the platform is not capable of 64-bit
-addressing. Rather, it may fail in this case simply because
-32-bit SAC addressing is done more efficiently than DAC addressing.
-Sparc64 is one platform which behaves in this way.
-
-Here is how you would handle a 64-bit capable device which can drive
-all 64-bits when accessing streaming DMA:
-
- int using_dac;
-
- if (!pci_set_dma_mask(pdev, DMA_BIT_MASK(64))) {
- using_dac = 1;
- } else if (!pci_set_dma_mask(pdev, DMA_BIT_MASK(32))) {
- using_dac = 0;
- } else {
- printk(KERN_WARNING
- "mydev: No suitable DMA available.\n");
- goto ignore_this_device;
- }
-
-If a card is capable of using 64-bit consistent allocations as well,
-the case would look like this:
-
- int using_dac, consistent_using_dac;
-
- if (!pci_set_dma_mask(pdev, DMA_BIT_MASK(64))) {
- using_dac = 1;
- consistent_using_dac = 1;
- pci_set_consistent_dma_mask(pdev, DMA_BIT_MASK(64));
- } else if (!pci_set_dma_mask(pdev, DMA_BIT_MASK(32))) {
- using_dac = 0;
- consistent_using_dac = 0;
- pci_set_consistent_dma_mask(pdev, DMA_BIT_MASK(32));
- } else {
- printk(KERN_WARNING
- "mydev: No suitable DMA available.\n");
- goto ignore_this_device;
- }
-
-pci_set_consistent_dma_mask() will always be able to set the same or a
-smaller mask as pci_set_dma_mask(). However for the rare case that a
-device driver only uses consistent allocations, one would have to
-check the return value from pci_set_consistent_dma_mask().
-
-Finally, if your device can only drive the low 24-bits of
-address during PCI bus mastering you might do something like:
-
- if (pci_set_dma_mask(pdev, DMA_BIT_MASK(24))) {
- printk(KERN_WARNING
- "mydev: 24-bit DMA addressing not available.\n");
- goto ignore_this_device;
- }
-
-When pci_set_dma_mask() is successful, and returns zero, the PCI layer
-saves away this mask you have provided. The PCI layer will use this
-information later when you make DMA mappings.
-
-There is a case which we are aware of at this time, which is worth
-mentioning in this documentation. If your device supports multiple
-functions (for example a sound card provides playback and record
-functions) and the various different functions have _different_
-DMA addressing limitations, you may wish to probe each mask and
-only provide the functionality which the machine can handle. It
-is important that the last call to pci_set_dma_mask() be for the
-most specific mask.
-
-Here is pseudo-code showing how this might be done:
-
- #define PLAYBACK_ADDRESS_BITS DMA_BIT_MASK(32)
- #define RECORD_ADDRESS_BITS DMA_BIT_MASK(24)
-
- struct my_sound_card *card;
- struct pci_dev *pdev;
-
- ...
- if (!pci_set_dma_mask(pdev, PLAYBACK_ADDRESS_BITS)) {
- card->playback_enabled = 1;
- } else {
- card->playback_enabled = 0;
- printk(KERN_WARNING "%s: Playback disabled due to DMA limitations.\n",
- card->name);
- }
- if (!pci_set_dma_mask(pdev, RECORD_ADDRESS_BITS)) {
- card->record_enabled = 1;
- } else {
- card->record_enabled = 0;
- printk(KERN_WARNING "%s: Record disabled due to DMA limitations.\n",
- card->name);
- }
-
-A sound card was used as an example here because this genre of PCI
-devices seems to be littered with ISA chips given a PCI front end,
-and thus retaining the 16MB DMA addressing limitations of ISA.
-
- Types of DMA mappings
-
-There are two types of DMA mappings:
-
-- Consistent DMA mappings which are usually mapped at driver
- initialization, unmapped at the end and for which the hardware should
- guarantee that the device and the CPU can access the data
- in parallel and will see updates made by each other without any
- explicit software flushing.
-
- Think of "consistent" as "synchronous" or "coherent".
-
- The current default is to return consistent memory in the low 32
- bits of the PCI bus space. However, for future compatibility you
- should set the consistent mask even if this default is fine for your
- driver.
-
- Good examples of what to use consistent mappings for are:
-
- - Network card DMA ring descriptors.
- - SCSI adapter mailbox command data structures.
- - Device firmware microcode executed out of
- main memory.
-
- The invariant these examples all require is that any CPU store
- to memory is immediately visible to the device, and vice
- versa. Consistent mappings guarantee this.
-
- IMPORTANT: Consistent DMA memory does not preclude the usage of
- proper memory barriers. The CPU may reorder stores to
- consistent memory just as it may normal memory. Example:
- if it is important for the device to see the first word
- of a descriptor updated before the second, you must do
- something like:
-
- desc->word0 = address;
- wmb();
- desc->word1 = DESC_VALID;
-
- in order to get correct behavior on all platforms.
-
- Also, on some platforms your driver may need to flush CPU write
- buffers in much the same way as it needs to flush write buffers
- found in PCI bridges (such as by reading a register's value
- after writing it).
-
-- Streaming DMA mappings which are usually mapped for one DMA transfer,
- unmapped right after it (unless you use pci_dma_sync_* below) and for which
- hardware can optimize for sequential accesses.
-
- This of "streaming" as "asynchronous" or "outside the coherency
- domain".
-
- Good examples of what to use streaming mappings for are:
-
- - Networking buffers transmitted/received by a device.
- - Filesystem buffers written/read by a SCSI device.
-
- The interfaces for using this type of mapping were designed in
- such a way that an implementation can make whatever performance
- optimizations the hardware allows. To this end, when using
- such mappings you must be explicit about what you want to happen.
-
-Neither type of DMA mapping has alignment restrictions that come
-from PCI, although some devices may have such restrictions.
-Also, systems with caches that aren't DMA-coherent will work better
-when the underlying buffers don't share cache lines with other data.
-
-
- Using Consistent DMA mappings.
-
-To allocate and map large (PAGE_SIZE or so) consistent DMA regions,
-you should do:
-
- dma_addr_t dma_handle;
-
- cpu_addr = pci_alloc_consistent(pdev, size, &dma_handle);
-
-where pdev is a struct pci_dev *. This may be called in interrupt context.
-You should use dma_alloc_coherent (see DMA-API.txt) for buses
-where devices don't have struct pci_dev (like ISA, EISA).
-
-This argument is needed because the DMA translations may be bus
-specific (and often is private to the bus which the device is attached
-to).
-
-Size is the length of the region you want to allocate, in bytes.
-
-This routine will allocate RAM for that region, so it acts similarly to
-__get_free_pages (but takes size instead of a page order). If your
-driver needs regions sized smaller than a page, you may prefer using
-the pci_pool interface, described below.
-
-The consistent DMA mapping interfaces, for non-NULL pdev, will by
-default return a DMA address which is SAC (Single Address Cycle)
-addressable. Even if the device indicates (via PCI dma mask) that it
-may address the upper 32-bits and thus perform DAC cycles, consistent
-allocation will only return > 32-bit PCI addresses for DMA if the
-consistent dma mask has been explicitly changed via
-pci_set_consistent_dma_mask(). This is true of the pci_pool interface
-as well.
-
-pci_alloc_consistent returns two values: the virtual address which you
-can use to access it from the CPU and dma_handle which you pass to the
-card.
-
-The cpu return address and the DMA bus master address are both
-guaranteed to be aligned to the smallest PAGE_SIZE order which
-is greater than or equal to the requested size. This invariant
-exists (for example) to guarantee that if you allocate a chunk
-which is smaller than or equal to 64 kilobytes, the extent of the
-buffer you receive will not cross a 64K boundary.
-
-To unmap and free such a DMA region, you call:
-
- pci_free_consistent(pdev, size, cpu_addr, dma_handle);
-
-where pdev, size are the same as in the above call and cpu_addr and
-dma_handle are the values pci_alloc_consistent returned to you.
-This function may not be called in interrupt context.
-
-If your driver needs lots of smaller memory regions, you can write
-custom code to subdivide pages returned by pci_alloc_consistent,
-or you can use the pci_pool API to do that. A pci_pool is like
-a kmem_cache, but it uses pci_alloc_consistent not __get_free_pages.
-Also, it understands common hardware constraints for alignment,
-like queue heads needing to be aligned on N byte boundaries.
-
-Create a pci_pool like this:
-
- struct pci_pool *pool;
-
- pool = pci_pool_create(name, pdev, size, align, alloc);
-
-The "name" is for diagnostics (like a kmem_cache name); pdev and size
-are as above. The device's hardware alignment requirement for this
-type of data is "align" (which is expressed in bytes, and must be a
-power of two). If your device has no boundary crossing restrictions,
-pass 0 for alloc; passing 4096 says memory allocated from this pool
-must not cross 4KByte boundaries (but at that time it may be better to
-go for pci_alloc_consistent directly instead).
-
-Allocate memory from a pci pool like this:
-
- cpu_addr = pci_pool_alloc(pool, flags, &dma_handle);
-
-flags are SLAB_KERNEL if blocking is permitted (not in_interrupt nor
-holding SMP locks), SLAB_ATOMIC otherwise. Like pci_alloc_consistent,
-this returns two values, cpu_addr and dma_handle.
-
-Free memory that was allocated from a pci_pool like this:
-
- pci_pool_free(pool, cpu_addr, dma_handle);
-
-where pool is what you passed to pci_pool_alloc, and cpu_addr and
-dma_handle are the values pci_pool_alloc returned. This function
-may be called in interrupt context.
-
-Destroy a pci_pool by calling:
-
- pci_pool_destroy(pool);
-
-Make sure you've called pci_pool_free for all memory allocated
-from a pool before you destroy the pool. This function may not
-be called in interrupt context.
-
- DMA Direction
-
-The interfaces described in subsequent portions of this document
-take a DMA direction argument, which is an integer and takes on
-one of the following values:
-
- PCI_DMA_BIDIRECTIONAL
- PCI_DMA_TODEVICE
- PCI_DMA_FROMDEVICE
- PCI_DMA_NONE
-
-One should provide the exact DMA direction if you know it.
-
-PCI_DMA_TODEVICE means "from main memory to the PCI device"
-PCI_DMA_FROMDEVICE means "from the PCI device to main memory"
-It is the direction in which the data moves during the DMA
-transfer.
-
-You are _strongly_ encouraged to specify this as precisely
-as you possibly can.
-
-If you absolutely cannot know the direction of the DMA transfer,
-specify PCI_DMA_BIDIRECTIONAL. It means that the DMA can go in
-either direction. The platform guarantees that you may legally
-specify this, and that it will work, but this may be at the
-cost of performance for example.
-
-The value PCI_DMA_NONE is to be used for debugging. One can
-hold this in a data structure before you come to know the
-precise direction, and this will help catch cases where your
-direction tracking logic has failed to set things up properly.
-
-Another advantage of specifying this value precisely (outside of
-potential platform-specific optimizations of such) is for debugging.
-Some platforms actually have a write permission boolean which DMA
-mappings can be marked with, much like page protections in the user
-program address space. Such platforms can and do report errors in the
-kernel logs when the PCI controller hardware detects violation of the
-permission setting.
-
-Only streaming mappings specify a direction, consistent mappings
-implicitly have a direction attribute setting of
-PCI_DMA_BIDIRECTIONAL.
-
-The SCSI subsystem tells you the direction to use in the
-'sc_data_direction' member of the SCSI command your driver is
-working on.
-
-For Networking drivers, it's a rather simple affair. For transmit
-packets, map/unmap them with the PCI_DMA_TODEVICE direction
-specifier. For receive packets, just the opposite, map/unmap them
-with the PCI_DMA_FROMDEVICE direction specifier.
-
- Using Streaming DMA mappings
-
-The streaming DMA mapping routines can be called from interrupt
-context. There are two versions of each map/unmap, one which will
-map/unmap a single memory region, and one which will map/unmap a
-scatterlist.
-
-To map a single region, you do:
-
- struct pci_dev *pdev = mydev->pdev;
- dma_addr_t dma_handle;
- void *addr = buffer->ptr;
- size_t size = buffer->len;
-
- dma_handle = pci_map_single(pdev, addr, size, direction);
-
-and to unmap it:
-
- pci_unmap_single(pdev, dma_handle, size, direction);
-
-You should call pci_unmap_single when the DMA activity is finished, e.g.
-from the interrupt which told you that the DMA transfer is done.
-
-Using cpu pointers like this for single mappings has a disadvantage,
-you cannot reference HIGHMEM memory in this way. Thus, there is a
-map/unmap interface pair akin to pci_{map,unmap}_single. These
-interfaces deal with page/offset pairs instead of cpu pointers.
-Specifically:
-
- struct pci_dev *pdev = mydev->pdev;
- dma_addr_t dma_handle;
- struct page *page = buffer->page;
- unsigned long offset = buffer->offset;
- size_t size = buffer->len;
-
- dma_handle = pci_map_page(pdev, page, offset, size, direction);
-
- ...
-
- pci_unmap_page(pdev, dma_handle, size, direction);
-
-Here, "offset" means byte offset within the given page.
-
-With scatterlists, you map a region gathered from several regions by:
-
- int i, count = pci_map_sg(pdev, sglist, nents, direction);
- struct scatterlist *sg;
-
- for_each_sg(sglist, sg, count, i) {
- hw_address[i] = sg_dma_address(sg);
- hw_len[i] = sg_dma_len(sg);
- }
-
-where nents is the number of entries in the sglist.
-
-The implementation is free to merge several consecutive sglist entries
-into one (e.g. if DMA mapping is done with PAGE_SIZE granularity, any
-consecutive sglist entries can be merged into one provided the first one
-ends and the second one starts on a page boundary - in fact this is a huge
-advantage for cards which either cannot do scatter-gather or have very
-limited number of scatter-gather entries) and returns the actual number
-of sg entries it mapped them to. On failure 0 is returned.
-
-Then you should loop count times (note: this can be less than nents times)
-and use sg_dma_address() and sg_dma_len() macros where you previously
-accessed sg->address and sg->length as shown above.
-
-To unmap a scatterlist, just call:
-
- pci_unmap_sg(pdev, sglist, nents, direction);
-
-Again, make sure DMA activity has already finished.
-
-PLEASE NOTE: The 'nents' argument to the pci_unmap_sg call must be
- the _same_ one you passed into the pci_map_sg call,
- it should _NOT_ be the 'count' value _returned_ from the
- pci_map_sg call.
-
-Every pci_map_{single,sg} call should have its pci_unmap_{single,sg}
-counterpart, because the bus address space is a shared resource (although
-in some ports the mapping is per each BUS so less devices contend for the
-same bus address space) and you could render the machine unusable by eating
-all bus addresses.
-
-If you need to use the same streaming DMA region multiple times and touch
-the data in between the DMA transfers, the buffer needs to be synced
-properly in order for the cpu and device to see the most uptodate and
-correct copy of the DMA buffer.
-
-So, firstly, just map it with pci_map_{single,sg}, and after each DMA
-transfer call either:
-
- pci_dma_sync_single_for_cpu(pdev, dma_handle, size, direction);
-
-or:
-
- pci_dma_sync_sg_for_cpu(pdev, sglist, nents, direction);
-
-as appropriate.
-
-Then, if you wish to let the device get at the DMA area again,
-finish accessing the data with the cpu, and then before actually
-giving the buffer to the hardware call either:
-
- pci_dma_sync_single_for_device(pdev, dma_handle, size, direction);
-
-or:
-
- pci_dma_sync_sg_for_device(dev, sglist, nents, direction);
-
-as appropriate.
-
-After the last DMA transfer call one of the DMA unmap routines
-pci_unmap_{single,sg}. If you don't touch the data from the first pci_map_*
-call till pci_unmap_*, then you don't have to call the pci_dma_sync_*
-routines at all.
-
-Here is pseudo code which shows a situation in which you would need
-to use the pci_dma_sync_*() interfaces.
-
- my_card_setup_receive_buffer(struct my_card *cp, char *buffer, int len)
- {
- dma_addr_t mapping;
-
- mapping = pci_map_single(cp->pdev, buffer, len, PCI_DMA_FROMDEVICE);
-
- cp->rx_buf = buffer;
- cp->rx_len = len;
- cp->rx_dma = mapping;
-
- give_rx_buf_to_card(cp);
- }
-
- ...
-
- my_card_interrupt_handler(int irq, void *devid, struct pt_regs *regs)
- {
- struct my_card *cp = devid;
-
- ...
- if (read_card_status(cp) == RX_BUF_TRANSFERRED) {
- struct my_card_header *hp;
-
- /* Examine the header to see if we wish
- * to accept the data. But synchronize
- * the DMA transfer with the CPU first
- * so that we see updated contents.
- */
- pci_dma_sync_single_for_cpu(cp->pdev, cp->rx_dma,
- cp->rx_len,
- PCI_DMA_FROMDEVICE);
-
- /* Now it is safe to examine the buffer. */
- hp = (struct my_card_header *) cp->rx_buf;
- if (header_is_ok(hp)) {
- pci_unmap_single(cp->pdev, cp->rx_dma, cp->rx_len,
- PCI_DMA_FROMDEVICE);
- pass_to_upper_layers(cp->rx_buf);
- make_and_setup_new_rx_buf(cp);
- } else {
- /* Just sync the buffer and give it back
- * to the card.
- */
- pci_dma_sync_single_for_device(cp->pdev,
- cp->rx_dma,
- cp->rx_len,
- PCI_DMA_FROMDEVICE);
- give_rx_buf_to_card(cp);
- }
- }
- }
-
-Drivers converted fully to this interface should not use virt_to_bus any
-longer, nor should they use bus_to_virt. Some drivers have to be changed a
-little bit, because there is no longer an equivalent to bus_to_virt in the
-dynamic DMA mapping scheme - you have to always store the DMA addresses
-returned by the pci_alloc_consistent, pci_pool_alloc, and pci_map_single
-calls (pci_map_sg stores them in the scatterlist itself if the platform
-supports dynamic DMA mapping in hardware) in your driver structures and/or
-in the card registers.
-
-All PCI drivers should be using these interfaces with no exceptions.
-It is planned to completely remove virt_to_bus() and bus_to_virt() as
-they are entirely deprecated. Some ports already do not provide these
-as it is impossible to correctly support them.
-
- Optimizing Unmap State Space Consumption
-
-On many platforms, pci_unmap_{single,page}() is simply a nop.
-Therefore, keeping track of the mapping address and length is a waste
-of space. Instead of filling your drivers up with ifdefs and the like
-to "work around" this (which would defeat the whole purpose of a
-portable API) the following facilities are provided.
-
-Actually, instead of describing the macros one by one, we'll
-transform some example code.
-
-1) Use DECLARE_PCI_UNMAP_{ADDR,LEN} in state saving structures.
- Example, before:
-
- struct ring_state {
- struct sk_buff *skb;
- dma_addr_t mapping;
- __u32 len;
- };
-
- after:
-
- struct ring_state {
- struct sk_buff *skb;
- DECLARE_PCI_UNMAP_ADDR(mapping)
- DECLARE_PCI_UNMAP_LEN(len)
- };
-
- NOTE: DO NOT put a semicolon at the end of the DECLARE_*()
- macro.
-
-2) Use pci_unmap_{addr,len}_set to set these values.
- Example, before:
-
- ringp->mapping = FOO;
- ringp->len = BAR;
-
- after:
-
- pci_unmap_addr_set(ringp, mapping, FOO);
- pci_unmap_len_set(ringp, len, BAR);
-
-3) Use pci_unmap_{addr,len} to access these values.
- Example, before:
-
- pci_unmap_single(pdev, ringp->mapping, ringp->len,
- PCI_DMA_FROMDEVICE);
-
- after:
-
- pci_unmap_single(pdev,
- pci_unmap_addr(ringp, mapping),
- pci_unmap_len(ringp, len),
- PCI_DMA_FROMDEVICE);
-
-It really should be self-explanatory. We treat the ADDR and LEN
-separately, because it is possible for an implementation to only
-need the address in order to perform the unmap operation.
-
- Platform Issues
-
-If you are just writing drivers for Linux and do not maintain
-an architecture port for the kernel, you can safely skip down
-to "Closing".
-
-1) Struct scatterlist requirements.
-
- Struct scatterlist must contain, at a minimum, the following
- members:
-
- struct page *page;
- unsigned int offset;
- unsigned int length;
-
- The base address is specified by a "page+offset" pair.
-
- Previous versions of struct scatterlist contained a "void *address"
- field that was sometimes used instead of page+offset. As of Linux
- 2.5., page+offset is always used, and the "address" field has been
- deleted.
-
-2) More to come...
-
- Handling Errors
-
-DMA address space is limited on some architectures and an allocation
-failure can be determined by:
-
-- checking if pci_alloc_consistent returns NULL or pci_map_sg returns 0
-
-- checking the returned dma_addr_t of pci_map_single and pci_map_page
- by using pci_dma_mapping_error():
-
- dma_addr_t dma_handle;
-
- dma_handle = pci_map_single(pdev, addr, size, direction);
- if (pci_dma_mapping_error(pdev, dma_handle)) {
- /*
- * reduce current DMA mapping usage,
- * delay and try again later or
- * reset driver.
- */
- }
-
- Closing

-form without the feedback and suggestions from numerous individuals.

+ Samsung ARM Linux Overview
+ ==========================
+
+Introduction
+------------
+
+ The Samsung range of ARM SoCs spans many similar devices, from the initial
+ ARM9 through to the newest ARM cores. This document shows an overview of
+ the current kernel support, how to use it and where to find the code
+ that supports this.
+
+ The currently supported SoCs are:
+
+ - S3C24XX: See Documentation/arm/Samsung-S3C24XX/Overview.txt for full list
+ - S3C64XX: S3C6400 and S3C6410
+ - S5PC6440
+
+ S5PC100 and S5PC110 support is currently being merged
+
+
+S3C24XX Systems
+---------------
+
+ There is still documentation in Documnetation/arm/Samsung-S3C24XX/ which
+ deals with the architecture and drivers specific to these devices.
+
+ See Documentation/arm/Samsung-S3C24XX/Overview.txt for more information
+ on the implementation details and specific support.
+
+
+Configuration
+-------------
+
+ A number of configurations are supplied, as there is no current way of
+ unifying all the SoCs into one kernel.
+
+ s5p6440_defconfig - S5P6440 specific default configuration
+ s5pc100_defconfig - S5PC100 specific default configuration
+
+
+Layout
+------
+
+ The directory layout is currently being restructured, and consists of
+ several platform directories and then the machine specific directories
+ of the CPUs being built for.
+
+ plat-samsung provides the base for all the implementations, and is the
+ last in the line of include directories that are processed for the build
+ specific information. It contains the base clock, GPIO and device definitions
+ to get the system running.
+
+ plat-s3c is the s3c24xx/s3c64xx platform directory, although it is currently
+ involved in other builds this will be phased out once the relevant code is
+ moved elsewhere.
+
+ plat-s3c24xx is for s3c24xx specific builds, see the S3C24XX docs.
+
+ plat-s3c64xx is for the s3c64xx specific bits, see the S3C24XX docs.
+
+ plat-s5p is for s5p specific builds, more to be added.

+2.4 Notification API
+--------------------
+
+There is mechanism which allows to get notifications about changing
+status of a cgroup.
+
+To register new notification handler you need:
+ - create a file descriptor for event notification using eventfd(2);
+ - open a control file to be monitored (e.g. memory.usage_in_bytes);
+ - write "<event_fd> <control_fd> <args>" to cgroup.event_control.
+ Interpretation of args is defined by control file implementation;
+
+eventfd will be woken up by control file implementation or when the
+cgroup is removed.
+
+To unregister notification handler just close eventfd.
+
+NOTE: Support of notifications should be implemented for the control
+file. See documentation for the subsystem.

+ CIRCULAR BUFFERS
+ ================
+
+By: David Howells <dhowells@redhat.com>
+ Paul E. McKenney <paulmck@linux.vnet.ibm.com>
+
+
+Linux provides a number of features that can be used to implement circular
+buffering. There are two sets of such features:
+
+ (1) Convenience functions for determining information about power-of-2 sized
+ buffers.
+
+ (2) Memory barriers for when the producer and the consumer of objects in the
+ buffer don't want to share a lock.
+
+To use these facilities, as discussed below, there needs to be just one
+producer and just one consumer. It is possible to handle multiple producers by
+serialising them, and to handle multiple consumers by serialising them.
+

+

+ - The consumer.
+
+
+==========================
+WHAT IS A CIRCULAR BUFFER?
+==========================
+
+First of all, what is a circular buffer? A circular buffer is a buffer of
+fixed, finite size into which there are two indices:
+
+ (1) A 'head' index - the point at which the producer inserts items into the
+ buffer.
+
+ (2) A 'tail' index - the point at which the consumer finds the next item in
+ the buffer.
+
+Typically when the tail pointer is equal to the head pointer, the buffer is
+empty; and the buffer is full when the head pointer is one less than the tail
+pointer.
+
+The head index is incremented when items are added, and the tail index when
+items are removed. The tail index should never jump the head index, and both
+indices should be wrapped to 0 when they reach the end of the buffer, thus
+allowing an infinite amount of data to flow through the buffer.
+
+Typically, items will all be of the same unit size, but this isn't strictly
+required to use the techniques below. The indices can be increased by more
+than 1 if multiple items or variable-sized items are to be included in the
+buffer, provided that neither index overtakes the other. The implementer must
+be careful, however, as a region more than one unit in size may wrap the end of
+the buffer and be broken into two segments.
+
+
+============================
+MEASURING POWER-OF-2 BUFFERS
+============================
+
+Calculation of the occupancy or the remaining capacity of an arbitrarily sized
+circular buffer would normally be a slow operation, requiring the use of a
+modulus (divide) instruction. However, if the buffer is of a power-of-2 size,
+then a much quicker bitwise-AND instruction can be used instead.
+
+Linux provides a set of macros for handling power-of-2 circular buffers. These
+can be made use of by:
+
+ #include <linux/circ_buf.h>
+
+The macros are:
+
+ (*) Measure the remaining capacity of a buffer:
+
+ CIRC_SPACE(head_index, tail_index, buffer_size);
+
+ This returns the amount of space left in the buffer[1] into which items
+ can be inserted.
+
+
+ (*) Measure the maximum consecutive immediate space in a buffer:
+
+ CIRC_SPACE_TO_END(head_index, tail_index, buffer_size);
+
+ This returns the amount of consecutive space left in the buffer[1] into
+ which items can be immediately inserted without having to wrap back to the
+ beginning of the buffer.
+
+
+ (*) Measure the occupancy of a buffer:
+
+ CIRC_CNT(head_index, tail_index, buffer_size);
+
+ This returns the number of items currently occupying a buffer[2].
+
+
+ (*) Measure the non-wrapping occupancy of a buffer:
+
+ CIRC_CNT_TO_END(head_index, tail_index, buffer_size);
+
+ This returns the number of consecutive items[2] that can be extracted from
+ the buffer without having to wrap back to the beginning of the buffer.
+
+
+Each of these macros will nominally return a value between 0 and buffer_size-1,
+however:
+
+ [1] CIRC_SPACE*() are intended to be used in the producer. To the producer
+ they will return a lower bound as the producer controls the head index,
+ but the consumer may still be depleting the buffer on another CPU and
+ moving the tail index.
+
+ To the consumer it will show an upper bound as the producer may be busy
+ depleting the space.
+
+ [2] CIRC_CNT*() are intended to be used in the consumer. To the consumer they
+ will return a lower bound as the consumer controls the tail index, but the
+ producer may still be filling the buffer on another CPU and moving the
+ head index.
+
+ To the producer it will show an upper bound as the consumer may be busy
+ emptying the buffer.
+
+ [3] To a third party, the order in which the writes to the indices by the
+ producer and consumer become visible cannot be guaranteed as they are
+ independent and may be made on different CPUs - so the result in such a
+ situation will merely be a guess, and may even be negative.
+
+
+===========================================
+USING MEMORY BARRIERS WITH CIRCULAR BUFFERS
+===========================================
+
+By using memory barriers in conjunction with circular buffers, you can avoid
+the need to:
+
+ (1) use a single lock to govern access to both ends of the buffer, thus
+ allowing the buffer to be filled and emptied at the same time; and
+
+ (2) use atomic counter operations.
+
+There are two sides to this: the producer that fills the buffer, and the
+consumer that empties it. Only one thing should be filling a buffer at any one
+time, and only one thing should be emptying a buffer at any one time, but the
+two sides can operate simultaneously.
+
+
+THE PRODUCER
+------------
+
+The producer will look something like this:
+
+ spin_lock(&producer_lock);
+
+ unsigned long head = buffer->head;
+ unsigned long tail = ACCESS_ONCE(buffer->tail);
+
+ if (CIRC_SPACE(head, tail, buffer->size) >= 1) {
+ /* insert one item into the buffer */
+ struct item *item = buffer[head];
+
+ produce_item(item);
+
+ smp_wmb(); /* commit the item before incrementing the head */
+
+ buffer->head = (head + 1) & (buffer->size - 1);
+
+ /* wake_up() will make sure that the head is committed before
+ * waking anyone up */
+ wake_up(consumer);
+ }
+
+ spin_unlock(&producer_lock);
+
+This will instruct the CPU that the contents of the new item must be written
+before the head index makes it available to the consumer and then instructs the
+CPU that the revised head index must be written before the consumer is woken.
+
+Note that wake_up() doesn't have to be the exact mechanism used, but whatever
+is used must guarantee a (write) memory barrier between the update of the head
+index and the change of state of the consumer, if a change of state occurs.
+
+
+THE CONSUMER
+------------
+
+The consumer will look something like this:
+
+ spin_lock(&consumer_lock);
+
+ unsigned long head = ACCESS_ONCE(buffer->head);
+ unsigned long tail = buffer->tail;
+
+ if (CIRC_CNT(head, tail, buffer->size) >= 1) {
+ /* read index before reading contents at that index */
+ smp_read_barrier_depends();
+
+ /* extract one item from the buffer */
+ struct item *item = buffer[tail];
+
+ consume_item(item);
+
+ smp_mb(); /* finish reading descriptor before incrementing tail */
+
+ buffer->tail = (tail + 1) & (buffer->size - 1);
+ }
+
+ spin_unlock(&consumer_lock);
+
+This will instruct the CPU to make sure the index is up to date before reading
+the new item, and then it shall make sure the CPU has finished reading the item
+before it writes the new tail pointer, which will erase the item.
+
+
+Note the use of ACCESS_ONCE() in both algorithms to read the opposition index.
+This prevents the compiler from discarding and reloading its cached value -
+which some compilers will do across smp_read_barrier_depends(). This isn't
+strictly needed if you can be sure that the opposition index will _only_ be
+used the once.

+
+1. Introduction:
+----------------
+Processor Clocking Control (PCC) is an interface between the platform
+firmware and OSPM. It is a mechanism for coordinating processor
+performance (ie: frequency) between the platform firmware and the OS.
+
+The PCC driver (pcc-cpufreq) allows OSPM to take advantage of the PCC
+interface.
+
+OS utilizes the PCC interface to inform platform firmware what frequency the
+OS wants for a logical processor. The platform firmware attempts to achieve
+the requested frequency. If the request for the target frequency could not be
+satisfied by platform firmware, then it usually means that power budget
+conditions are in place, and "power capping" is taking place.
+
+1.1 PCC interface:
+------------------
+The complete PCC specification is available here:
+http://www.acpica.org/download/Processor-Clocking-Control-v1p0.pdf
+
+PCC relies on a shared memory region that provides a channel for communication
+between the OS and platform firmware. PCC also implements a "doorbell" that
+is used by the OS to inform the platform firmware that a command has been
+sent.
+
+The ACPI PCCH() method is used to discover the location of the PCC shared
+memory region. The shared memory region header contains the "command" and
+"status" interface. PCCH() also contains details on how to access the platform
+doorbell.
+
+The following commands are supported by the PCC interface:
+* Get Average Frequency
+* Set Desired Frequency
+
+The ACPI PCCP() method is implemented for each logical processor and is
+used to discover the offsets for the input and output buffers in the shared
+memory region.
+
+When PCC mode is enabled, the platform will not expose processor performance
+or throttle states (_PSS, _TSS and related ACPI objects) to OSPM. Therefore,
+the native P-state driver (such as acpi-cpufreq for Intel, powernow-k8 for
+AMD) will not load.
+
+However, OSPM remains in control of policy. The governor (eg: "ondemand")
+computes the required performance for each processor based on server workload.
+The PCC driver fills in the command interface, and the input buffer and
+communicates the request to the platform firmware. The platform firmware is
+responsible for delivering the requested performance.
+
+Each PCC command is "global" in scope and can affect all the logical CPUs in
+the system. Therefore, PCC is capable of performing "group" updates. With PCC
+the OS is capable of getting/setting the frequency of all the logical CPUs in
+the system with a single call to the BIOS.
+
+1.1.1 Get Average Frequency:
+----------------------------
+This command is used by the OSPM to query the running frequency of the
+processor since the last time this command was completed. The output buffer
+indicates the average unhalted frequency of the logical processor expressed as
+a percentage of the nominal (ie: maximum) CPU frequency. The output buffer
+also signifies if the CPU frequency is limited by a power budget condition.
+
+1.1.2 Set Desired Frequency:
+----------------------------
+This command is used by the OSPM to communicate to the platform firmware the
+desired frequency for a logical processor. The output buffer is currently
+ignored by OSPM. The next invocation of "Get Average Frequency" will inform
+OSPM if the desired frequency was achieved or not.
+
+1.2 Platforms affected:
+-----------------------
+The PCC driver will load on any system where the platform firmware:
+* supports the PCC interface, and the associated PCCH() and PCCP() methods
+* assumes responsibility for managing the hardware clocking controls in order
+to deliver the requested processor performance
+
+Currently, certain HP ProLiant platforms implement the PCC interface. On those
+platforms PCC is the "default" choice.
+
+However, it is possible to disable this interface via a BIOS setting. In
+such an instance, as is also the case on platforms where the PCC interface
+is not implemented, the PCC driver will fail to load silently.
+
+2. Driver and /sys details:
+---------------------------
+When the driver loads, it merely prints the lowest and the highest CPU
+frequencies supported by the platform firmware.
+
+The PCC driver loads with a message such as:
+pcc-cpufreq: (v1.00.00) driver loaded with frequency limits: 1600 MHz, 2933
+MHz
+
+This means that the OPSM can request the CPU to run at any frequency in
+between the limits (1600 MHz, and 2933 MHz) specified in the message.
+
+Internally, there is no need for the driver to convert the "target" frequency
+to a corresponding P-state.
+
+The VERSION number for the driver will be of the format v.xy.ab.
+eg: 1.00.02
+ ----- --
+ | |
+ | -- this will increase with bug fixes/enhancements to the driver
+ |-- this is the version of the PCC specification the driver adheres to
+
+
+The following is a brief discussion on some of the fields exported via the
+/sys filesystem and how their values are affected by the PCC driver:
+
+2.1 scaling_available_frequencies:
+----------------------------------
+scaling_available_frequencies is not created in /sys. No intermediate
+frequencies need to be listed because the BIOS will try to achieve any
+frequency, within limits, requested by the governor. A frequency does not have
+to be strictly associated with a P-state.
+
+2.2 cpuinfo_transition_latency:
+-------------------------------
+The cpuinfo_transition_latency field is 0. The PCC specification does
+not include a field to expose this value currently.
+
+2.3 cpuinfo_cur_freq:
+---------------------
+A) Often cpuinfo_cur_freq will show a value different than what is declared
+in the scaling_available_frequencies or scaling_cur_freq, or scaling_max_freq.
+This is due to "turbo boost" available on recent Intel processors. If certain
+conditions are met the BIOS can achieve a slightly higher speed than requested
+by OSPM. An example:
+
+scaling_cur_freq : 2933000
+cpuinfo_cur_freq : 3196000
+
+B) There is a round-off error associated with the cpuinfo_cur_freq value.
+Since the driver obtains the current frequency as a "percentage" (%) of the
+nominal frequency from the BIOS, sometimes, the values displayed by
+scaling_cur_freq and cpuinfo_cur_freq may not match. An example:
+
+scaling_cur_freq : 1600000
+cpuinfo_cur_freq : 1583000
+
+In this example, the nominal frequency is 2933 MHz. The driver obtains the
+current frequency, cpuinfo_cur_freq, as 54% of the nominal frequency:
+
+ 54% of 2933 MHz = 1583 MHz
+
+Nominal frequency is the maximum frequency of the processor, and it usually
+corresponds to the frequency of the P0 P-state.
+
+2.4 related_cpus:
+-----------------
+The related_cpus field is identical to affected_cpus.
+
+affected_cpus : 4
+related_cpus : 4
+
+Currently, the PCC driver does not evaluate _PSD. The platforms that support
+PCC do not implement SW_ALL. So OSPM doesn't need to perform any coordination
+to ensure that the same frequency is requested of all dependent CPUs.
+
+3. Caveats:
+-----------
+The "cpufreq_stats" module in its present form cannot be loaded and
+expected to work with the PCC driver. Since the "cpufreq_stats" module
+provides information wrt each P-state, it is not applicable to the PCC driver.

+Ceph Distributed File System
+============================
+
+Ceph is a distributed network file system designed to provide good
+performance, reliability, and scalability.
+
+Basic features include:
+
+ * POSIX semantics
+ * Seamless scaling from 1 to many thousands of nodes
+ * High availability and reliability. No single point of failure.
+ * N-way replication of data across storage nodes
+ * Fast recovery from node failures
+ * Automatic rebalancing of data on node addition/removal
+ * Easy deployment: most FS components are userspace daemons
+
+Also,
+ * Flexible snapshots (on any directory)
+ * Recursive accounting (nested files, directories, bytes)
+
+In contrast to cluster filesystems like GFS, OCFS2, and GPFS that rely
+on symmetric access by all clients to shared block devices, Ceph
+separates data and metadata management into independent server
+clusters, similar to Lustre. Unlike Lustre, however, metadata and
+storage nodes run entirely as user space daemons. Storage nodes
+utilize btrfs to store data objects, leveraging its advanced features
+(checksumming, metadata replication, etc.). File data is striped
+across storage nodes in large chunks to distribute workload and
+facilitate high throughputs. When storage nodes fail, data is
+re-replicated in a distributed fashion by the storage nodes themselves
+(with some minimal coordination from a cluster monitor), making the
+system extremely efficient and scalable.
+
+Metadata servers effectively form a large, consistent, distributed
+in-memory cache above the file namespace that is extremely scalable,
+dynamically redistributes metadata in response to workload changes,
+and can tolerate arbitrary (well, non-Byzantine) node failures. The
+metadata server takes a somewhat unconventional approach to metadata
+storage to significantly improve performance for common workloads. In
+particular, inodes with only a single link are embedded in
+directories, allowing entire directories of dentries and inodes to be
+loaded into its cache with a single I/O operation. The contents of
+extremely large directories can be fragmented and managed by
+independent metadata servers, allowing scalable concurrent access.
+
+The system offers automatic data rebalancing/migration when scaling
+from a small cluster of just a few nodes to many hundreds, without
+requiring an administrator carve the data set into static volumes or
+go through the tedious process of migrating data between servers.
+When the file system approaches full, new nodes can be easily added
+and things will "just work."
+
+Ceph includes flexible snapshot mechanism that allows a user to create
+a snapshot on any subdirectory (and its nested contents) in the
+system. Snapshot creation and deletion are as simple as 'mkdir
+.snap/foo' and 'rmdir .snap/foo'.
+
+Ceph also provides some recursive accounting on directories for nested
+files and bytes. That is, a 'getfattr -d foo' on any directory in the
+system will reveal the total number of nested regular files and
+subdirectories, and a summation of all nested file sizes. This makes
+the identification of large disk space consumers relatively quick, as
+no 'du' or similar recursive scan of the file system is required.
+
+
+Mount Syntax
+============
+
+The basic mount syntax is:
+
+ # mount -t ceph monip[:port][,monip2[:port]...]:/[subdir] mnt
+
+You only need to specify a single monitor, as the client will get the
+full list when it connects. (However, if the monitor you specify
+happens to be down, the mount won't succeed.) The port can be left
+off if the monitor is using the default. So if the monitor is at
+1.2.3.4,
+
+ # mount -t ceph 1.2.3.4:/ /mnt/ceph
+
+is sufficient. If /sbin/mount.ceph is installed, a hostname can be
+used instead of an IP address.
+
+
+
+Mount Options
+=============
+
+ ip=A.B.C.D[:N]
+ Specify the IP and/or port the client should bind to locally.
+ There is normally not much reason to do this. If the IP is not
+ specified, the client's IP address is determined by looking at the
+ address it's connection to the monitor originates from.
+
+ wsize=X
+ Specify the maximum write size in bytes. By default there is no
+ maximum. Ceph will normally size writes based on the file stripe
+ size.
+
+ rsize=X
+ Specify the maximum readahead.
+
+ mount_timeout=X
+ Specify the timeout value for mount (in seconds), in the case
+ of a non-responsive Ceph file system. The default is 30
+ seconds.
+
+ rbytes
+ When stat() is called on a directory, set st_size to 'rbytes',
+ the summation of file sizes over all files nested beneath that
+ directory. This is the default.
+
+ norbytes
+ When stat() is called on a directory, set st_size to the
+ number of entries in that directory.
+
+ nocrc
+ Disable CRC32C calculation for data writes. If set, the storage node
+ must rely on TCP's error correction to detect data corruption
+ in the data payload.
+
+ noasyncreaddir
+ Disable client's use its local cache to satisfy readdir
+ requests. (This does not change correctness; the client uses
+ cached metadata only when a lease or capability ensures it is
+ valid.)

+
+The LogFS Flash Filesystem
+==========================
+
+Specification
+=============
+
+Superblocks
+-----------
+
+Two superblocks exist at the beginning and end of the filesystem.
+Each superblock is 256 Bytes large, with another 3840 Bytes reserved
+for future purposes, making a total of 4096 Bytes.
+
+Superblock locations may differ for MTD and block devices. On MTD the
+first non-bad block contains a superblock in the first 4096 Bytes and
+the last non-bad block contains a superblock in the last 4096 Bytes.
+On block devices, the first 4096 Bytes of the device contain the first
+superblock and the last aligned 4096 Byte-block contains the second
+superblock.
+
+For the most part, the superblocks can be considered read-only. They
+are written only to correct errors detected within the superblocks,
+move the journal and change the filesystem parameters through tunefs.
+As a result, the superblock does not contain any fields that require
+constant updates, like the amount of free space, etc.
+
+Segments
+--------
+
+The space in the device is split up into equal-sized segments.
+Segments are the primary write unit of LogFS. Within each segments,
+writes happen from front (low addresses) to back (high addresses. If
+only a partial segment has been written, the segment number, the
+current position within and optionally a write buffer are stored in
+the journal.
+
+Segments are erased as a whole. Therefore Garbage Collection may be
+required to completely free a segment before doing so.
+
+Journal
+--------
+
+The journal contains all global information about the filesystem that
+is subject to frequent change. At mount time, it has to be scanned
+for the most recent commit entry, which contains a list of pointers to
+all currently valid entries.
+
+Object Store
+------------
+
+All space except for the superblocks and journal is part of the object
+store. Each segment contains a segment header and a number of
+objects, each consisting of the object header and the payload.
+Objects are either inodes, directory entries (dentries), file data
+blocks or indirect blocks.
+
+Levels
+------
+
+Garbage collection (GC) may fail if all data is written
+indiscriminately. One requirement of GC is that data is seperated
+roughly according to the distance between the tree root and the data.
+Effectively that means all file data is on level 0, indirect blocks
+are on levels 1, 2, 3 4 or 5 for 1x, 2x, 3x, 4x or 5x indirect blocks,
+respectively. Inode file data is on level 6 for the inodes and 7-11
+for indirect blocks.
+
+Each segment contains objects of a single level only. As a result,
+each level requires its own seperate segment to be open for writing.
+
+Inode File
+----------
+
+All inodes are stored in a special file, the inode file. Single
+exception is the inode file's inode (master inode) which for obvious
+reasons is stored in the journal instead. Instead of data blocks, the
+leaf nodes of the inode files are inodes.
+
+Aliases
+-------
+
+Writes in LogFS are done by means of a wandering tree. A naïve
+implementation would require that for each write or a block, all
+parent blocks are written as well, since the block pointers have
+changed. Such an implementation would not be very efficient.
+
+In LogFS, the block pointer changes are cached in the journal by means
+of alias entries. Each alias consists of its logical address - inode
+number, block index, level and child number (index into block) - and
+the changed data. Any 8-byte word can be changes in this manner.
+
+Currently aliases are used for block pointers, file size, file used
+bytes and the height of an inodes indirect tree.
+
+Segment Aliases
+---------------
+
+Related to regular aliases, these are used to handle bad blocks.
+Initially, bad blocks are handled by moving the affected segment
+content to a spare segment and noting this move in the journal with a
+segment alias, a simple (to, from) tupel. GC will later empty this
+segment and the alias can be removed again. This is used on MTD only.
+
+Vim
+---
+
+By cleverly predicting the life time of data, it is possible to
+seperate long-living data from short-living data and thereby reduce
+the GC overhead later. Each type of distinc life expectency (vim) can
+have a seperate segment open for writing. Each (level, vim) tupel can
+be open just once. If an open segment with unknown vim is encountered
+at mount time, it is closed and ignored henceforth.
+
+Indirect Tree
+-------------
+
+Inodes in LogFS are similar to FFS-style filesystems with direct and
+indirect block pointers. One difference is that LogFS uses a single
+indirect pointer that can be either a 1x, 2x, etc. indirect pointer.
+A height field in the inode defines the height of the indirect tree
+and thereby the indirection of the pointer.
+
+Another difference is the addressing of indirect blocks. In LogFS,
+the first 16 pointers in the first indirect block are left empty,
+corresponding to the 16 direct pointers in the inode. In ext2 (maybe
+others as well) the first pointer in the first indirect block
+corresponds to logical block 12, skipping the 12 direct pointers.
+So where ext2 is using arithmetic to better utilize space, LogFS keeps
+arithmetic simple and uses compression to save space.
+
+Compression
+-----------
+
+Both file data and metadata can be compressed. Compression for file
+data can be enabled with chattr +c and disabled with chattr -c. Doing
+so has no effect on existing data, but new data will be stored
+accordingly. New inodes will inherit the compression flag of the
+parent directory.
+
+Metadata is always compressed. However, the space accounting ignores
+this and charges for the uncompressed size. Failing to do so could
+result in GC failures when, after moving some data, indirect blocks
+compress worse than previously. Even on a 100% full medium, GC may
+not consume any extra space, so the compression gains are lost space
+to the user.
+
+However, they are not lost space to the filesystem internals. By
+cheating the user for those bytes, the filesystem gained some slack
+space and GC will run less often and faster.
+
+Garbage Collection and Wear Leveling
+------------------------------------
+
+Garbage collection is invoked whenever the number of free segments
+falls below a threshold. The best (known) candidate is picked based
+on the least amount of valid data contained in the segment. All
+remaining valid data is copied elsewhere, thereby invalidating it.
+
+The GC code also checks for aliases and writes then back if their
+number gets too large.
+
+Wear leveling is done by occasionally picking a suboptimal segment for
+garbage collection. If a stale segments erase count is significantly
+lower than the active segments' erase counts, it will be picked. Wear
+leveling is rate limited, so it will never monopolize the device for
+more than one segment worth at a time.
+
+Values for "occasionally", "significantly lower" are compile time
+constants.
+
+Hashed directories
+------------------
+
+To satisfy efficient lookup(), directory entries are hashed and
+located based on the hash. In order to both support large directories
+and not be overly inefficient for small directories, several hash
+tables of increasing size are used. For each table, the hash value
+modulo the table size gives the table index.
+
+Tables sizes are chosen to limit the number of indirect blocks with a
+fully populated table to 0, 1, 2 or 3 respectively. So the first
+table contains 16 entries, the second 512-16, etc.
+
+The last table is special in several ways. First its size depends on
+the effective 32bit limit on telldir/seekdir cookies. Since logfs
+uses the upper half of the address space for indirect blocks, the size
+is limited to 2^31. Secondly the table contains hash buckets with 16
+entries each.
+
+Using single-entry buckets would result in birthday "attacks". At
+just 2^16 used entries, hash collisions would be likely (P >= 0.5).
+My math skills are insufficient to do the combinatorics for the 17x
+collisions necessary to overflow a bucket, but testing showed that in

+188,057,130 entries with an average of 315,149,915 entries. So for
+directory sizes of up to a million, bucket overflows should be
+virtually impossible under normal circumstances.
+
+With carefully chosen filenames, it is obviously possible to cause an
+overflow with just 21 entries (4 higher tables + 16 entries + 1). So

+
+Device Address Space
+--------------------
+
+A device address space is used for caching. Both block devices and
+MTD provide functions to either read a single page or write a segment.
+Partial segments may be written for data integrity, but where possible
+complete segments are written for performance on simple block device
+flash media.
+
+Meta Inodes
+-----------
+
+Inodes are stored in the inode file, which is just a regular file for
+most purposes. At umount time, however, the inode file needs to
+remain open until all dirty inodes are written. So
+generic_shutdown_super() may not close this inode, but shouldn't
+complain about remaining inodes due to the inode file either. Same
+goes for mapping inode of the device address space.
+
+Currently logfs uses a hack that essentially copies part of fs/inode.c
+code over. A general solution would be preferred.
+
+Indirect block mapping
+----------------------
+
+With compression, the block device (or mapping inode) cannot be used
+to cache indirect blocks. Some other place is required. Currently
+logfs uses the top half of each inode's address space. The low 8TB
+(on 32bit) are filled with file data, the high 8TB are used for
+indirect blocks.
+
+One problem is that 16TB files created on 64bit systems actually have
+data in the top 8TB. But files >16TB would cause problems anyway, so
+only the limit has changed.

+Description
+-----------
+
+This driver implements support for the Analog Devices ADT7411 chip. There may
+be other chips that implement this interface.
+
+The ADT7411 can use an I2C/SMBus compatible 2-wire interface or an
+SPI-compatible 4-wire interface. It provides a 10-bit analog to digital
+converter which measures 1 temperature, vdd and 8 input voltages. It has an
+internal temperature sensor, but an external one can also be connected (one
+loses 2 inputs then). There are high- and low-limit registers for all inputs.
+
+Check the datasheet for details.

+
+in0_input - vdd voltage input
+in[1-8]_input - analog 1-8 input

+
+Besides standard interfaces, this driver adds (0 = off, 1 = on):
+
+ adc_ref_vdd - Use vdd as reference instead of 2.25 V
+ fast_sampling - Sample at 22.5 kHz instead of 1.4 kHz, but drop filters
+ no_average - Turn off averaging over 16 samples

-======================

-Supported chips:
- * Analog Devices ADT7473

- Datasheet: Publicly available at the Analog Devices website

-Author: Darrick J. Wong
-
-This driver is depreacted, please use the adt7475 driver instead.
-
-Description
------------
-
-This driver implements support for the Analog Devices ADT7473 chip family.
-
-The ADT7473 uses the 2-wire interface compatible with the SMBUS 2.0
-specification. Using an analog to digital converter it measures three (3)
-temperatures and two (2) voltages. It has four (4) 16-bit counters for
-measuring fan speed. There are three (3) PWM outputs that can be used
-to control fan speed.
-
-A sophisticated control system for the PWM outputs is designed into the
-ADT7473 that allows fan speed to be adjusted automatically based on any of the
-three temperature sensors. Each PWM output is individually adjustable and
-programmable. Once configured, the ADT7473 will adjust the PWM outputs in
-response to the measured temperatures without further host intervention.
-This feature can also be disabled for manual control of the PWM's.
-
-Each of the measured inputs (voltage, temperature, fan speed) has
-corresponding high/low limit values. The ADT7473 will signal an ALARM if
-any measured value exceeds either limit.
-
-The ADT7473 samples all inputs continuously. The driver will not read
-the registers more often than once every other second. Further,
-configuration data is only read once per minute.
-
-Special Features
-----------------
-
-The ADT7473 have a 10-bit ADC and can therefore measure temperatures
-with 0.25 degC resolution. Temperature readings can be configured either
-for twos complement format or "Offset 64" format, wherein 63 is subtracted
-from the raw value to get the temperature value.
-
-The Analog Devices datasheet is very detailed and describes a procedure for
-determining an optimal configuration for the automatic PWM control.
-
-Configuration Notes
--------------------
-
-Besides standard interfaces driver adds the following:
-
-* PWM Control
-
-* pwm#_auto_point1_pwm and temp#_auto_point1_temp and
-* pwm#_auto_point2_pwm and temp#_auto_point2_temp -
-
-point1: Set the pwm speed at a lower temperature bound.
-point2: Set the pwm speed at a higher temperature bound.
-
-The ADT7473 will scale the pwm between the lower and higher pwm speed when
-the temperature is between the two temperature boundaries. PWM values range
-from 0 (off) to 255 (full speed). Fan speed will be set to maximum when the
-temperature sensor associated with the PWM control exceeds temp#_max.
-
-Notes
------
-
-The NVIDIA binary driver presents an ADT7473 chip via an on-card i2c bus.
-Unfortunately, they fail to set the i2c adapter class, so this driver may
-fail to find the chip until the nvidia driver is patched.

+Kernel driver asc7621
+==================
+
+Supported chips:
+ Andigilog aSC7621 and aSC7621a
+ Prefix: 'asc7621'
+ Addresses scanned: I2C 0x2c, 0x2d, 0x2e
+ Datasheet: http://www.fairview5.com/linux/asc7621/asc7621.pdf
+
+Author:
+ George Joseph
+
+Description provided by Dave Pivin @ Andigilog:
+
+Andigilog has both the PECI and pre-PECI versions of the Heceta-6, as
+Intel calls them. Heceta-6e has high frequency PWM and Heceta-6p has
+added PECI and a 4th thermal zone. The Andigilog aSC7611 is the
+Heceta-6e part and aSC7621 is the Heceta-6p part. They are both in
+volume production, shipping to Intel and their subs.
+
+We have enhanced both parts relative to the governing Intel
+specification. First enhancement is temperature reading resolution. We
+have used registers below 20h for vendor-specific functions in addition
+to those in the Intel-specified vendor range.
+
+Our conversion process produces a result that is reported as two bytes.
+The fan speed control uses this finer value to produce a "step-less" fan
+PWM output. These two bytes are "read-locked" to guarantee that once a
+high or low byte is read, the other byte is locked-in until after the
+next read of any register. So to get an atomic reading, read high or low
+byte, then the very next read should be the opposite byte. Our data
+sheet says 10-bits of resolution, although you may find the lower bits
+are active, they are not necessarily reliable or useful externally. We
+chose not to mask them.
+
+We employ significant filtering that is user tunable as described in the
+data sheet. Our temperature reports and fan PWM outputs are very smooth
+when compared to the competition, in addition to the higher resolution
+temperature reports. The smoother PWM output does not require user
+intervention.
+
+We offer GPIO features on the former VID pins. These are open-drain
+outputs or inputs and may be used as general purpose I/O or as alarm
+outputs that are based on temperature limits. These are in 19h and 1Ah.
+
+We offer flexible mapping of temperature readings to thermal zones. Any
+temperature may be mapped to any zone, which has a default assignment
+that follows Intel's specs.
+
+Since there is a fan to zone assignment that allows for the "hotter" of
+a set of zones to control the PWM of an individual fan, but there is no
+indication to the user, we have added an indicator that shows which zone
+is currently controlling the PWM for a given fan. This is in register
+00h.
+
+Both remote diode temperature readings may be given an offset value such
+that the reported reading as well as the temperature used to determine
+PWM may be offset for system calibration purposes.
+
+PECI Extended configuration allows for having more than two domains per
+PECI address and also provides an enabling function for each PECI
+address. One could use our flexible zone assignment to have a zone
+assigned to up to 4 PECI addresses. This is not possible in the default
+Intel configuration. This would be useful in multi-CPU systems with
+individual fans on each that would benefit from individual fan control.
+This is in register 0Eh.
+
+The tachometer measurement system is flexible and able to adapt to many
+fan types. We can also support pulse-stretched PWM so that 3-wire fans
+may be used. These characteristics are in registers 04h to 07h.
+
+Finally, we have added a tach disable function that turns off the tach
+measurement system for individual tachs in order to save power. That is
+in register 75h.
+
+--
+aSC7621 Product Description
+
+The aSC7621 has a two wire digital interface compatible with SMBus 2.0.
+Using a 10-bit ADC, the aSC7621 measures the temperature of two remote diode
+connected transistors as well as its own die. Support for Platform
+Environmental Control Interface (PECI) is included.
+
+Using temperature information from these four zones, an automatic fan speed
+control algorithm is employed to minimize acoustic impact while achieving
+recommended CPU temperature under varying operational loads.
+
+To set fan speed, the aSC7621 has three independent pulse width modulation
+(PWM) outputs that are controlled by one, or a combination of three,
+temperature zones. Both high- and low-frequency PWM ranges are supported.
+
+The aSC7621 also includes a digital filter that can be invoked to smooth
+temperature readings for better control of fan speed and minimum acoustic
+impact.
+
+The aSC7621 has tachometer inputs to measure fan speed on up to four fans.
+Limit and status registers for all measured values are included to alert
+the system host that any measurements are outside of programmed limits
+via status registers.
+
+System voltages of VCCP, 2.5V, 3.3V, 5.0V, and 12V motherboard power are
+monitored efficiently with internal scaling resistors.

+Automatic fan speed control (old interface)
+-------------------------------------------
+
+The driver supports the old interface to automatic fan speed control
+which is implemented by IT8705F chips up to revision F and IT8712F
+chips up to revision G.
+
+This interface implements 4 temperature vs. PWM output trip points.
+The PWM output of trip point 4 is always the maximum value (fan running
+at full speed) while the PWM output of the other 3 trip points can be
+freely chosen. The temperature of all 4 trip points can be freely chosen.
+Additionally, trip point 1 has an hysteresis temperature attached, to
+prevent fast switching between fan on and off.
+
+The chip automatically computes the PWM output value based on the input
+temperature, based on this simple rule: if the temperature value is
+between trip point N and trip point N+1 then the PWM output value is
+the one of trip point N. The automatic control mode is less flexible
+than the manual control mode, but it reacts faster, is more robust and
+doesn't use CPU cycles.
+
+Trip points must be set properly before switching to automatic fan speed
+control mode. The driver will perform basic integrity checks before
+actually switching to automatic control mode.

+===========

+SMBus Alert was introduced in Revision 1.0 of the specification.
+
+The SMBus alert protocol allows several SMBus slave devices to share a

+to know which slave triggered the interrupt.
+
+This is implemented the following way in the Linux kernel:
+* I2C bus drivers which support SMBus alert should call
+ i2c_setup_smbus_alert() to setup SMBus alert support.
+* I2C drivers for devices which can trigger SMBus alerts should implement

+Explaining the dreaded "No init found." boot hang message
+=========================================================
+
+OK, so you've got this pretty unintuitive message (currently located
+in init/main.c) and are wondering what the H*** went wrong.
+Some high-level reasons for failure (listed roughly in order of execution)
+to load the init binary are:
+A) Unable to mount root FS
+B) init binary doesn't exist on rootfs
+C) broken console device
+D) binary exists but dependencies not available
+E) binary cannot be loaded
+
+Detailed explanations:
+0) Set "debug" kernel parameter (in bootloader config file or CONFIG_CMDLINE)
+ to get more detailed kernel messages.
+A) make sure you have the correct root FS type
+ (and root= kernel parameter points to the correct partition),
+ required drivers such as storage hardware (such as SCSI or USB!)
+ and filesystem (ext3, jffs2 etc.) are builtin (alternatively as modules,
+ to be pre-loaded by an initrd)
+C) Possibly a conflict in console= setup --> initial console unavailable.
+ E.g. some serial consoles are unreliable due to serial IRQ issues (e.g.
+ missing interrupt-based configuration).
+ Try using a different console= device or e.g. netconsole= .
+D) e.g. required library dependencies of the init binary such as
+ /lib/ld-linux.so.2 missing or broken. Use readelf -d <INIT>|grep NEEDED
+ to find out which libraries are required.
+E) make sure the binary's architecture matches your hardware.
+ E.g. i386 vs. x86_64 mismatch, or trying to load x86 on ARM hardware.
+ In case you tried loading a non-binary file here (shell script?),
+ you should make sure that the script specifies an interpreter in its shebang
+ header line (#!/...) that is fully working (including its library
+ dependencies). And before tackling scripts, better first test a simple
+ non-script binary such as /bin/sh and confirm its successful execution.
+ To find out more, add code to init/main.c to display kernel_execve()s
+ return values.
+
+Please extend this explanation whenever you find new failure causes
+(after all loading the init binary is a CRITICAL and hard transition step
+which needs to be made as painless as possible), then submit patch to LKML.
+Further TODOs:
+- Implement the various run_init_process() invocations via a struct array
+ which can then store the kernel_execve() result value and on failure
+ log it all by iterating over _all_ results (very important usability fix).
+- try to make the implementation itself more helpful in general,
+ e.g. by providing additional error messages at affected places.

+Before optimizing a probe, Kprobes performs the following safety checks:
+
+- Kprobes verifies that the region that will be replaced by the jump
+instruction (the "optimized region") lies entirely within one function.
+(A jump instruction is multiple bytes, and so may overlay multiple
+instructions.)
+
+- Kprobes analyzes the entire function and verifies that there is no
+jump into the optimized region. Specifically:
+ - the function contains no indirect jump;
+ - the function contains no instruction that causes an exception (since
+ the fixup code triggered by the exception could jump back into the
+ optimized region -- Kprobes checks the exception tables to verify this);
+ and
+ - there is no near jump to the optimized region (other than to the first
+ byte).
+
+- For each instruction in the optimized region, Kprobes verifies that
+the instruction can be executed out of line.
+
+1.4.3 Preparing Detour Buffer
+
+Next, Kprobes prepares a "detour" buffer, which contains the following
+instruction sequence:
+- code to push the CPU's registers (emulating a breakpoint trap)
+- a call to the trampoline code which calls user's probe handlers.
+- code to restore registers
+- the instructions from the optimized region
+- a jump back to the original execution path.
+
+1.4.4 Pre-optimization
+
+After preparing the detour buffer, Kprobes verifies that none of the
+following situations exist:
+- The probe has either a break_handler (i.e., it's a jprobe) or a
+post_handler.
+- Other instructions in the optimized region are probed.
+- The probe is disabled.
+In any of the above cases, Kprobes won't start optimizing the probe.
+Since these are temporary situations, Kprobes tries to start
+optimizing it again if the situation is changed.
+
+If the kprobe can be optimized, Kprobes enqueues the kprobe to an
+optimizing list, and kicks the kprobe-optimizer workqueue to optimize
+it. If the to-be-optimized probepoint is hit before being optimized,
+Kprobes returns control to the original instruction path by setting
+the CPU's instruction pointer to the copied code in the detour buffer
+-- thus at least avoiding the single-step.
+
+1.4.5 Optimization
+
+The Kprobe-optimizer doesn't insert the jump instruction immediately;
+rather, it calls synchronize_sched() for safety first, because it's
+possible for a CPU to be interrupted in the middle of executing the
+optimized region(*). As you know, synchronize_sched() can ensure
+that all interruptions that were active when synchronize_sched()
+was called are done, but only if CONFIG_PREEMPT=n. So, this version
+of kprobe optimization supports only kernels with CONFIG_PREEMPT=n.(**)
+
+After that, the Kprobe-optimizer calls stop_machine() to replace
+the optimized region with a jump instruction to the detour buffer,
+using text_poke_smp().
+
+1.4.6 Unoptimization
+
+When an optimized kprobe is unregistered, disabled, or blocked by
+another kprobe, it will be unoptimized. If this happens before
+the optimization is complete, the kprobe is just dequeued from the
+optimized list. If the optimization has been done, the jump is
+replaced with the original code (except for an int3 breakpoint in
+the first byte) by using text_poke_smp().
+
+(*)Please imagine that the 2nd instruction is interrupted and then
+the optimizer replaces the 2nd instruction with the jump *address*
+while the interrupt handler is running. When the interrupt
+returns to original address, there is no valid instruction,
+and it causes an unexpected result.
+
+(**)This optimization-safety checking may be replaced with the
+stop-machine method that ksplice uses for supporting a CONFIG_PREEMPT=y
+kernel.
+
+NOTE for geeks:
+The jump optimization changes the kprobe's pre_handler behavior.
+Without optimization, the pre_handler can change the kernel's execution
+path by changing regs->ip and returning 1. However, when the probe
+is optimized, that modification is ignored. Thus, if you want to
+tweak the kernel's execution path, you need to suppress optimization,
+using one of the following techniques:
+- Specify an empty function for the kprobe's post_handler or break_handler.
+ or
+- Config CONFIG_OPTPROBES=n.
+ or
+- Execute 'sysctl -w debug.kprobes_optimization=n'
+
2. Architectures Supported

+Introduction
+------------
+CAIF is a MUX protocol used by ST-Ericsson cellular modems for
+communication between Modem and host. The host processes can open virtual AT
+channels, initiate GPRS Data connections, Video channels and Utility Channels.
+The Utility Channels are general purpose pipes between modem and host.
+
+ST-Ericsson modems support a number of transports between modem
+and host. Currently, UART and Loopback are available for Linux.
+
+
+Architecture:
+------------
+The implementation of CAIF is divided into:
+* CAIF Socket Layer, Kernel API, and Net Device.
+* CAIF Core Protocol Implementation
+* CAIF Link Layer, implemented as NET devices.

+Using the Kernel API
+----------------------
+The Kernel API is used for accessing CAIF channels from the
+kernel.
+The user of the API has to implement two callbacks for receive
+and control.
+The receive callback gives a CAIF packet as a SKB. The control
+callback will
+notify of channel initialization complete, and flow-on/flow-
+off.

+===========================
+===========================
+
+CAIF Core Protocol Layer
+=========================================
+
+CAIF Core layer implements the CAIF protocol as defined by ST-Ericsson.
+It implements the CAIF protocol stack in a layered approach, where
+each layer described in the specification is implemented as a separate layer.
+The architecture is inspired by the design patterns "Protocol Layer" and
+"Protocol Packet".
+
+== CAIF structure ==
+The Core CAIF implementation contains:
+ - Simple implementation of CAIF.
+ - Layered architecture (a la Streams), each layer in the CAIF
+ specification is implemented in a separate c-file.
+ - Clients must implement PHY layer to access physical HW
+ with receive and transmit functions.
+ - Clients must call configuration function to add PHY layer.
+ - Clients must implement CAIF layer to consume/produce
+ CAIF payload with receive and transmit functions.
+ - Clients must call configuration function to add and connect the
+ Client layer.
+ - When receiving / transmitting CAIF Packets (cfpkt), ownership is passed
+ to the called function (except for framing layers' receive functions
+ or if a transmit function returns an error, in which case the caller
+ must free the packet).
+
+Layered Architecture
+--------------------
+The CAIF protocol can be divided into two parts: Support functions and Protocol
+Implementation. The support functions include:
+
+ - CFPKT CAIF Packet. Implementation of CAIF Protocol Packet. The
+ CAIF Packet has functions for creating, destroying and adding content
+ and for adding/extracting header and trailers to protocol packets.
+
+ - CFLST CAIF list implementation.
+
+ - CFGLUE CAIF Glue. Contains OS Specifics, such as memory
+ allocation, endianness, etc.
+
+The CAIF Protocol implementation contains:
+
+ - CFCNFG CAIF Configuration layer. Configures the CAIF Protocol
+ Stack and provides a Client interface for adding Link-Layer and
+ Driver interfaces on top of the CAIF Stack.
+
+ - CFCTRL CAIF Control layer. Encodes and Decodes control messages
+ such as enumeration and channel setup. Also matches request and
+ response messages.
+
+ - CFSERVL General CAIF Service Layer functionality; handles flow
+ control and remote shutdown requests.
+
+ - CFVEI CAIF VEI layer. Handles CAIF AT Channels on VEI (Virtual
+ External Interface). This layer encodes/decodes VEI frames.
+
+ - CFDGML CAIF Datagram layer. Handles CAIF Datagram layer (IP
+ traffic), encodes/decodes Datagram frames.
+
+ - CFMUX CAIF Mux layer. Handles multiplexing between multiple
+ physical bearers and multiple channels such as VEI, Datagram, etc.
+ The MUX keeps track of the existing CAIF Channels and
+ Physical Instances and selects the apropriate instance based
+ on Channel-Id and Physical-ID.
+
+ - CFFRML CAIF Framing layer. Handles Framing i.e. Frame length
+ and frame checksum.
+
+ - CFSERL CAIF Serial layer. Handles concatenation/split of frames
+ into CAIF Frames with correct length.
+

+ +---------+ +---------+
+
+
+In this layered approach the following "rules" apply.
+ - All layers embed the same structure "struct cflayer"
+ - A layer does not depend on any other layer's private data.
+ - Layers are stacked by setting the pointers
+ layer->up , layer->dn
+ - In order to send data upwards, each layer should do
+ layer->up->receive(layer->up, packet);
+ - In order to send data downwards, each layer should do
+ layer->dn->transmit(layer->dn, packet);
+
+
+Linux Driver Implementation
+===========================
+
+Linux GPRS Net Device and CAIF socket are implemented on top of the
+CAIF Core protocol. The Net device and CAIF socket have an instance of
+'struct cflayer', just like the CAIF Core protocol stack.
+Net device and Socket implement the 'receive()' function defined by
+'struct cflayer', just like the rest of the CAIF stack. In this way, transmit and
+receive of packets is handled as by the rest of the layers: the 'dn->transmit()'
+function is called in order to transmit data.
+
+The layer on top of the CAIF Core implementation is
+sometimes referred to as the "Client layer".
+
+
+Configuration of Link Layer
+---------------------------
+The Link Layer is implemented as Linux net devices (struct net_device).
+Payload handling and registration is done using standard Linux mechanisms.
+
+The CAIF Protocol relies on a loss-less link layer without implementing
+retransmission. This implies that packet drops must not happen.
+Therefore a flow-control mechanism is implemented where the physical
+interface can initiate flow stop for all CAIF Channels.

+
+=== Start ===
+If you have compiled CAIF for modules do:
+
+$modprobe crc_ccitt
+$modprobe caif
+$modprobe caif_socket
+$modprobe chnl_net
+
+
+=== Preparing the setup with a STE modem ===
+
+If you are working on integration of CAIF you should make sure
+that the kernel is built with module support.
+
+There are some things that need to be tweaked to get the host TTY correctly
+set up to talk to the modem.
+Since the CAIF stack is running in the kernel and we want to use the existing
+TTY, we are installing our physical serial driver as a line discipline above
+the TTY device.
+
+To achieve this we need to install the N_CAIF ldisc from user space.
+The benefit is that we can hook up to any TTY.
+
+The use of Start-of-frame-extension (STX) must also be set as
+module parameter "ser_use_stx".
+
+Normally Frame Checksum is always used on UART, but this is also provided as a
+module parameter "ser_use_fcs".
+
+$ modprobe caif_serial ser_ttyname=/dev/ttyS0 ser_use_stx=yes
+$ ifconfig caif_ttyS0 up
+
+PLEASE NOTE: There is a limitation in Android shell.
+ It only accepts one argument to insmod/modprobe!
+
+=== Trouble shooting ===
+
+There are debugfs parameters provided for serial communication.
+/sys/kernel/debug/caif_serial/<tty-name>/
+
+* ser_state: Prints the bit-mask status where
+ - 0x02 means SENDING, this is a transient state.
+ - 0x10 means FLOW_OFF_SENT, i.e. the previous frame has not been sent
+ and is blocking further send operation. Flow OFF has been propagated
+ to all CAIF Channels using this TTY.
+
+* tty_status: Prints the bit-mask tty status information
+ - 0x01 - tty->warned is on.
+ - 0x02 - tty->low_latency is on.
+ - 0x04 - tty->packed is on.
+ - 0x08 - tty->flow_stopped is on.
+ - 0x10 - tty->hw_stopped is on.
+ - 0x20 - tty->stopped is on.
+
+* last_tx_msg: Binary blob Prints the last transmitted frame.
+ This can be printed with
+ $od --format=x1 /sys/kernel/debug/caif_serial/<tty>/last_rx_msg.
+ The first two tx messages sent look like this. Note: The initial
+ byte 02 is start of frame extension (STX) used for re-syncing
+ upon errors.
+
+ - Enumeration:
+ 0000000 02 05 00 00 03 01 d2 02
+ | | | | | |
+ STX(1) | | | |
+ Length(2)| | |
+ Control Channel(1)
+ Command:Enumeration(1)
+ Link-ID(1)
+ Checksum(2)
+ - Channel Setup:
+ 0000000 02 07 00 00 00 21 a1 00 48 df
+ | | | | | | | |
+ STX(1) | | | | | |
+ Length(2)| | | | |
+ Control Channel(1)
+ Command:Channel Setup(1)
+ Channel Type(1)
+ Priority and Link-ID(1)
+ Endpoint(1)
+ Checksum(2)
+
+* last_rx_msg: Prints the last transmitted frame.
+ The RX messages for LinkSetup look almost identical but they have the
+ bit 0x20 set in the command bit, and Channel Setup has added one byte
+ before Checksum containing Channel ID.
+ NOTE: Several CAIF Messages might be concatenated. The maximum debug
+ buffer size is 128 bytes.
+
+== Error Scenarios:
+- last_tx_msg contains channel setup message and last_rx_msg is empty ->
+ The host seems to be able to send over the UART, at least the CAIF ldisc get
+ notified that sending is completed.
+
+- last_tx_msg contains enumeration message and last_rx_msg is empty ->
+ The host is not able to send the message from UART, the tty has not been
+ able to complete the transmit operation.
+
+- if /sys/kernel/debug/caif_serial/<tty>/tty_status is non-zero there
+ might be problems transmitting over UART.
+ E.g. host and modem wiring is not correct you will typically see
+ tty_status = 0x10 (hw_stopped) and ser_state = 0x10 (FLOW_OFF_SENT).
+ You will probably see the enumeration message in last_tx_message
+ and empty last_rx_message.

+L2TPv3 PPP pseudowires.
+L2TPv3 IP encapsulation.
+Netlink sockets for L2TPv3 configuration management.
+
+History
+=======
+
+The original pppol2tp driver was introduced in 2.6.23 and provided
+L2TPv2 functionality (rfc2661). L2TPv2 is used to tunnel one or more PPP
+sessions over a UDP tunnel.
+
+L2TPv3 (rfc3931) changes the protocol to allow different frame types
+to be passed over an L2TP tunnel by moving the PPP-specific parts of
+the protocol out of the core L2TP packet headers. Each frame type is
+known as a pseudowire type. Ethernet, PPP, HDLC, Frame Relay and ATM
+pseudowires for L2TP are defined in separate RFC standards. Another
+change for L2TPv3 is that it can be carried directly over IP with no
+UDP header (UDP is optional). It is also possible to create static
+unmanaged L2TPv3 tunnels manually without a control protocol
+(userspace daemon) to manage them.
+
+To support L2TPv3, the original pppol2tp driver was split up to
+separate the L2TP and PPP functionality. Existing L2TPv2 userspace
+apps should be unaffected as the original pppol2tp sockets API is
+retained. L2TPv3, however, uses netlink to manage L2TPv3 tunnels and
+sessions.
Design
======
-The PPPoL2TP driver, drivers/net/pppol2tp.c, provides a mechanism by
-which PPP frames carried through an L2TP session are passed through
-the kernel's PPP subsystem. The standard PPP daemon, pppd, handles all
-PPP interaction with the peer. PPP network interfaces are created for
-each local PPP endpoint.
+The L2TP protocol separates control and data frames. The L2TP kernel
+drivers handle only L2TP data frames; control frames are always
+handled by userspace. L2TP control frames carry messages between L2TP
+clients/servers and are used to setup / teardown tunnels and
+sessions. An L2TP client or server is implemented in userspace.
-The L2TP protocol http://www.faqs.org/rfcs/rfc2661.html defines L2TP
-control and data frames. L2TP control frames carry messages between
-L2TP clients/servers and are used to setup / teardown tunnels and
-sessions. An L2TP client or server is implemented in userspace and
-will use a regular UDP socket per tunnel. L2TP data frames carry PPP
-frames, which may be PPP control or PPP data. The kernel's PPP
+Each L2TP tunnel is implemented using a UDP or L2TPIP socket; L2TPIP
+provides L2TPv3 IP encapsulation (no UDP) and is implemented using a
+new l2tpip socket family. The tunnel socket is typically created by
+userspace, though for unmanaged L2TPv3 tunnels, the socket can also be
+created by the kernel. Each L2TP session (pseudowire) gets a network
+interface instance. In the case of PPP, these interfaces are created
+indirectly by pppd using a pppol2tp socket. In the case of ethernet,
+the netdevice is created upon a netlink request to create an L2TPv3
+ethernet pseudowire.
+
+For PPP, the PPPoL2TP driver, net/l2tp/l2tp_ppp.c, provides a
+mechanism by which PPP frames carried through an L2TP session are
+passed through the kernel's PPP subsystem. The standard PPP daemon,
+pppd, handles all PPP interaction with the peer. PPP network
+interfaces are created for each local PPP endpoint. The kernel's PPP
subsystem arranges for PPP control frames to be delivered to pppd,
while data frames are forwarded as usual.
+For ethernet, the L2TPETH driver, net/l2tp/l2tp_eth.c, implements a
+netdevice driver, managing virtual ethernet devices, one per
+pseudowire. These interfaces can be managed using standard Linux tools
+such as "ip" and "ifconfig". If only IP frames are passed over the
+tunnel, the interface can be given an IP addresses of itself and its
+peer. If non-IP frames are to be passed over the tunnel, the interface
+can be added to a bridge using brctl. All L2TP datapath protocol
+functions are handled by the L2TP core driver.
+
Each tunnel and session within a tunnel is assigned a unique tunnel_id
and session_id. These ids are carried in the L2TP header of every
-control and data packet. The pppol2tp driver uses them to lookup
-internal tunnel and/or session contexts. Zero tunnel / session ids are
-treated specially - zero ids are never assigned to tunnels or sessions
-in the network. In the driver, the tunnel context keeps a pointer to
-the tunnel UDP socket. The session context keeps a pointer to the
-PPPoL2TP socket, as well as other data that lets the driver interface
-to the kernel PPP subsystem.
+control and data packet. (Actually, in L2TPv3, the tunnel_id isn't
+present in data frames - it is inferred from the IP connection on
+which the packet was received.) The L2TP driver uses the ids to lookup
+internal tunnel and/or session contexts to determine how to handle the
+packet. Zero tunnel / session ids are treated specially - zero ids are
+never assigned to tunnels or sessions in the network. In the driver,
+the tunnel context keeps a reference to the tunnel UDP or L2TPIP
+socket. The session context holds data that lets the driver interface
+to the kernel's network frame type subsystems, i.e. PPP, ethernet.
-Note that the pppol2tp kernel driver handles only L2TP data frames;
-L2TP control frames are simply passed up to userspace in the UDP
-tunnel socket. The kernel handles all datapath aspects of the
-protocol, including data packet resequencing (if enabled).

+Internal Implementation
+=======================
-The PPPoL2TP driver was developed as part of the OpenL2TP project by
+The driver keeps a struct l2tp_tunnel context per L2TP tunnel and a
+struct l2tp_session context for each session. The l2tp_tunnel is
+always associated with a UDP or L2TP/IP socket and keeps a list of
+sessions in the tunnel. The l2tp_session context keeps kernel state
+about the session. It has private data which is used for data specific
+to the session type. With L2TPv2, the session always carried PPP
+traffic. With L2TPv3, the session can also carry ethernet frames
+(ethernet pseudowire) or other data types such as ATM, HDLC or Frame
+Relay.
+
+When a tunnel is first opened, the reference count on the socket is
+increased using sock_hold(). This ensures that the kernel socket
+cannot be removed while L2TP's data structures reference it.
+
+Some L2TP sessions also have a socket (PPP pseudowires) while others
+do not (ethernet pseudowires). We can't use the socket reference count
+as the reference count for session contexts. The L2TP implementation
+therefore has its own internal reference counts on the session
+contexts.
+
+To Do
+=====
+
+Add L2TP tunnel switching support. This would route tunneled traffic
+from one L2TP tunnel into another. Specified in
+http://tools.ietf.org/html/draft-ietf-l2tpext-tunnel-switching-08

+ STMicroelectronics 10/100/1000 Synopsys Ethernet driver
+
+Copyright (C) 2007-2010 STMicroelectronics Ltd
+Author: Giuseppe Cavallaro <peppe.cavallaro@st.com>
+
+This is the driver for the MAC 10/100/1000 on-chip Ethernet controllers
+(Synopsys IP blocks); it has been fully tested on STLinux platforms.
+
+Currently this network device driver is for all STM embedded MAC/GMAC
+(7xxx SoCs).
+
+DWC Ether MAC 10/100/1000 Universal version 3.41a and DWC Ether MAC 10/100
+Universal version 4.0 have been used for developing the first code
+implementation.
+
+Please, for more information also visit: www.stlinux.com
+
+1) Kernel Configuration
+The kernel configuration option is STMMAC_ETH:
+ Device Drivers ---> Network device support ---> Ethernet (1000 Mbit) --->
+ STMicroelectronics 10/100/1000 Ethernet driver (STMMAC_ETH)
+
+2) Driver parameters list:
+ debug: message level (0: no output, 16: all);
+ phyaddr: to manually provide the physical address to the PHY device;
+ dma_rxsize: DMA rx ring size;
+ dma_txsize: DMA tx ring size;
+ buf_sz: DMA buffer size;
+ tc: control the HW FIFO threshold;
+ tx_coe: Enable/Disable Tx Checksum Offload engine;
+ watchdog: transmit timeout (in milliseconds);
+ flow_ctrl: Flow control ability [on/off];
+ pause: Flow Control Pause Time;
+ tmrate: timer period (only if timer optimisation is configured).
+
+3) Command line options
+Driver parameters can be also passed in command line by using:
+ stmmaceth=dma_rxsize:128,dma_txsize:512
+
+4) Driver information and notes
+
+4.1) Transmit process
+The xmit method is invoked when the kernel needs to transmit a packet; it sets
+the descriptors in the ring and informs the DMA engine that there is a packet
+ready to be transmitted.
+Once the controller has finished transmitting the packet, an interrupt is
+triggered; So the driver will be able to release the socket buffers.
+By default, the driver sets the NETIF_F_SG bit in the features field of the
+net_device structure enabling the scatter/gather feature.
+
+4.2) Receive process
+When one or more packets are received, an interrupt happens. The interrupts
+are not queued so the driver has to scan all the descriptors in the ring during
+the receive process.
+This is based on NAPI so the interrupt handler signals only if there is work to be
+done, and it exits.
+Then the poll method will be scheduled at some future point.
+The incoming packets are stored, by the DMA, in a list of pre-allocated socket
+buffers in order to avoid the memcpy (Zero-copy).
+
+4.3) Timer-Driver Interrupt
+Instead of having the device that asynchronously notifies the frame receptions, the
+driver configures a timer to generate an interrupt at regular intervals.
+Based on the granularity of the timer, the frames that are received by the device
+will experience different levels of latency. Some NICs have dedicated timer
+device to perform this task. STMMAC can use either the RTC device or the TMU
+channel 2 on STLinux platforms.
+The timers frequency can be passed to the driver as parameter; when change it,
+take care of both hardware capability and network stability/performance impact.
+Several performance tests on STM platforms showed this optimisation allows to spare
+the CPU while having the maximum throughput.
+
+4.4) WOL
+Wake up on Lan feature through Magic Frame is only supported for the GMAC
+core.
+
+4.5) DMA descriptors
+Driver handles both normal and enhanced descriptors. The latter has been only
+tested on DWC Ether MAC 10/100/1000 Universal version 3.41a.
+
+4.6) Ethtool support
+Ethtool is supported. Driver statistics and internal errors can be taken using:
+ethtool -S ethX command. It is possible to dump registers etc.
+
+4.7) Jumbo and Segmentation Offloading
+Jumbo frames are supported and tested for the GMAC.
+The GSO has been also added but it's performed in software.
+LRO is not supported.
+
+4.8) Physical
+The driver is compatible with PAL to work with PHY and GPHY devices.
+
+4.9) Platform information
+Several information came from the platform; please refer to the
+driver's Header file in include/linux directory.

+ int bus_id;

+#ifdef CONFIG_STM_DRIVERS
+ struct stm_pad_config *pad_config;
+#endif
+ void *bsp_priv;

+
+Where:
+- pbl (Programmable Burst Length) is maximum number of
+ beats to be transferred in one DMA transaction.
+ GMAC also enables the 4xPBL by default.
+- fix_mac_speed and bus_setup are used to configure internal target
+ registers (on STM platforms);
+- has_gmac: GMAC core is on board (get it at run-time in the next step);
+- bus_id: bus identifier.

+struct plat_stmmacphy_data {
+ int bus_id;
+ int phy_addr;
+ unsigned int phy_mask;
+ int interface;
+ int (*phy_reset)(void *priv);

+
+Where:
+- bus_id: bus identifier;
+- phy_addr: physical address used for the attached phy device;
+ set it to -1 to get it at run-time;
+- interface: physical MII interface mode;
+- phy_reset: hook to reset HW function.
+
+TODO:
+- Continue to make the driver more generic and suitable for other Synopsys
+ Ethernet controllers used on other architectures (i.e. ARM).
+- 10G controllers are not supported.
+- MAC uses Normal descriptors and GMAC uses enhanced ones.
+ This is a limit that should be reviewed. MAC could want to
+ use the enhanced structure.
+- Checksumming: Rx/Tx csum is done in HW in case of GMAC only.
+- Review the timer optimisation code to use an embedded device that seems to be
+ available in new chip generations.

DEVICE IMPLEMENTATION
A driver which supports hardware time stamping must support the
-SIOCSHWTSTAMP ioctl. Time stamps for received packets must be stored
-in the skb with skb_hwtstamp_set().
+SIOCSHWTSTAMP ioctl and update the supplied struct hwtstamp_config with
+the actual values as described in the section on SIOCSHWTSTAMP.
+
+Time stamps for received packets must be stored in the skb. To get a pointer
+to the shared time stamp structure of the skb call skb_hwtstamps(). Then
+set the time stamps in the structure:
+
+struct skb_shared_hwtstamps {
+ /* hardware time stamp transformed into duration
+ * since arbitrary point in time
+ */
+ ktime_t hwtstamp;
+ ktime_t syststamp; /* hwtstamp transformed to system time base */
+};
Time stamps for outgoing packets are to be generated as follows:
-- In hard_start_xmit(), check if skb_hwtstamp_check_tx_hardware()
- returns non-zero. If yes, then the driver is expected
- to do hardware time stamping.
+- In hard_start_xmit(), check if skb_tx(skb)->hardware is set no-zero.
+ If yes, then the driver is expected to do hardware time stamping.
- If this is possible for the skb and requested, then declare
- that the driver is doing the time stamping by calling
- skb_hwtstamp_tx_in_progress(). A driver not supporting
- hardware time stamping doesn't do that. A driver must never
- touch sk_buff::tstamp! It is used to store how time stamping
- for an outgoing packets is to be done.
+ that the driver is doing the time stamping by setting the field
+ skb_tx(skb)->in_progress non-zero. You might want to keep a pointer
+ to the associated skb for the next step and not free the skb. A driver
+ not supporting hardware time stamping doesn't do that. A driver must
+ never touch sk_buff::tstamp! It is used to store software generated
+ time stamps by the network subsystem.
- As soon as the driver has sent the packet and/or obtained a
hardware time stamp for it, it passes the time stamp back by
calling skb_hwtstamp_tx() with the original skb, the raw
- hardware time stamp and a handle to the device (necessary
- to convert the hardware time stamp to system time). If obtaining
- the hardware time stamp somehow fails, then the driver should
- not fall back to software time stamping. The rationale is that
- this would occur at a later time in the processing pipeline
- than other software time stamping and therefore could lead
- to unexpected deltas between time stamps.
-- If the driver did not call skb_hwtstamp_tx_in_progress(), then
+ hardware time stamp. skb_hwtstamp_tx() clones the original skb and
+ adds the timestamps, therefore the original skb has to be freed now.
+ If obtaining the hardware time stamp somehow fails, then the driver
+ should not fall back to software time stamping. The rationale is that
+ this would occur at a later time in the processing pipeline than other
+ software time stamping and therefore could lead to unexpected deltas

+- If the driver did not call set skb_tx(skb)->in_progress, then
dev_hard_start_xmit() checks whether software time stamping
is wanted as fallback and potentially generates the time stamp.

Interrupt Handling
~~~~~~~~~~~~~~~~~~
-In rare but some cases, the interrupt isn't properly handled as
-default. You would notice this by the DMA transfer error reported by
-ALSA PCM core, for example. Using MSI might help in such a case.
-Pass `enable_msi=1` option for enabling MSI.
+HD-audio driver uses MSI as default (if available) since 2.6.33
+kernel as MSI works better on some machines, and in general, it's
+better for performance. However, Nvidia controllers showed bad
+regressions with MSI (especially in a combination with AMD chipset),
+thus we disabled MSI for them.
+
+There seem also still other devices that don't work with MSI. If you
+see a regression wrt the sound quality (stuttering, etc) or a lock-up
+in the recent kernel, try to pass `enable_msi=0` option to disable
+MSI. If it works, you can add the known bad device to the blacklist
+defined in hda_intel.c. In such a case, please report and give the
+patch back to the upstream developer.

-All three suspend/resume methods are always called while holding the

If a driver wants to block all suspend/resume calls during some
-critical section, it can simply acquire udev->pm_mutex. Note that
-calls to resume may be triggered indirectly. Block IO due to memory
-allocations can make the vm subsystem resume a device. Thus while
-holding this lock you must not allocate memory with GFP_KERNEL or
-GFP_NOFS.
-
-Alternatively, if the critical section might call some of the
-usb_autopm_* routines, the driver can avoid deadlock by doing:
-
- down(&udev->dev.sem);
- rc = usb_autopm_get_interface(intf);
-
-and at the end of the critical section:
-
- if (!rc)
- usb_autopm_put_interface(intf);
- up(&udev->dev.sem);
-
-Holding the device semaphore will block all external PM calls, and the
-usb_autopm_get_interface() will prevent any internal PM calls, even if
-it fails. (Exercise: Why?)
-
-The rules for locking order are:
-
- Never acquire any device semaphore while holding any PM mutex.
-
- Never acquire udev->pm_mutex while holding the PM mutex for
- a device that isn't a descendant of udev.
-
-In other words, PM mutexes should only be acquired going up the device
-tree, and they should be acquired only after locking all the device
-semaphores you need to hold. These rules don't matter to drivers very
-much; they usually affect just the USB core.
-
-Still, drivers do need to be careful. For example, many drivers use a
-private mutex to synchronize their normal I/O activities with their
-disconnect method. Now if the driver supports autosuspend then it
-must call usb_autopm_put_interface() from somewhere -- maybe from its
-close method. It should make the call while holding the private mutex,
-since a driver shouldn't call any of the usb_autopm_* functions for an
-interface from which it has been unbound.
-
-But the usb_autpm_* routines always acquire the device's PM mutex, and
-consequently the locking order has to be: private mutex first, PM
-mutex second. Since the suspend method is always called with the PM
-mutex held, it mustn't try to acquire the private mutex. It has to
-synchronize with the driver's I/O activities in some other way.
+critical section, the best way is to lock the device and call
+usb_autopm_get_interface() (and do the reverse at the end of the
+critical section). Holding the device semaphore will block all
+external PM calls, and the usb_autopm_get_interface() will prevent any
+internal PM calls, even if it fails. (Exercise: Why?)
Interaction between dynamic PM and system PM
@@ -499,22 +465,11 @@
Dynamic power management and system power management can interact in
a couple of ways.
-Firstly, a device may already be manually suspended or autosuspended
-when a system suspend occurs. Since system suspends are supposed to

-following the system resume. The 2.6.23 kernel obeys this principle

-do get resumed when the system wakes up. (Presumably they will be
-autosuspended again after their idle-delay time expires.) In later

-(There is an exception. If a device would undergo a reset-resume
-instead of a normal resume, and the device is enabled for remote
-wakeup, then the reset-resume takes place even if the device was
-already suspended when the system suspend began. The justification is
-that a reset-resume is a kind of remote-wakeup event. Or to put it

-Running Linux on the Voyager Architecture
-=========================================
-
-For full details and current project status, see
-
-http://www.hansenpartnership.com/voyager
-
-The voyager architecture was designed by NCR in the mid 80s to be a
-fully SMP capable RAS computing architecture built around intel's 486
-chip set. The voyager came in three levels of architectural
-sophistication: 3,4 and 5 --- 1 and 2 never made it out of prototype.
-The linux patches support only the Level 5 voyager architecture (any
-machine class 3435 and above).
-
-The Voyager Architecture
-------------------------
-
-Voyager machines consist of a Baseboard with a 386 diagnostic
-processor, a Power Supply Interface (PSI) a Primary and possibly
-Secondary Microchannel bus and between 2 and 20 voyager slots. The
-voyager slots can be populated with memory and cpu cards (up to 4GB
-memory and from 1 486 to 32 Pentium Pro processors). Internally, the
-voyager has a dual arbitrated system bus and a configuration and test
-bus (CAT). The voyager bus speed is 40MHz. Therefore (since all
-voyager cards are dual ported for each system bus) the maximum
-transfer rate is 320Mb/s but only if you have your slot configuration
-tuned (only memory cards can communicate with both busses at once, CPU
-cards utilise them one at a time).
-
-Voyager SMP
------------
-
-Since voyager was the first intel based SMP system, it is slightly
-more primitive than the Intel IO-APIC approach to SMP. Voyager allows
-arbitrary interrupt routing (including processor affinity routing) of
-all 16 PC type interrupts. However it does this by using a modified
-5259 master/slave chip set instead of an APIC bus. Additionally,
-voyager supports Cross Processor Interrupts (CPI) equivalent to the
-APIC IPIs. There are two routed voyager interrupt lines provided to
-each slot.
-
-Processor Cards
----------------
-
-These come in single, dyadic and quad configurations (the quads are
-problematic--see later). The maximum configuration is 8 quad cards
-for 32 way SMP.
-
-Quad Processors
----------------
-
-Because voyager only supplies two interrupt lines to each Processor
-card, the Quad processors have to be configured (and Bootstrapped) in
-as a pair of Master/Slave processors.
-
-In fact, most Quad cards only accept one VIC interrupt line, so they
-have one interrupt handling processor (called the VIC extended
-processor) and three non-interrupt handling processors.
-
-Current Status
---------------
-
-The System will boot on Mono, Dyad and Quad cards. There was
-originally a Quad boot problem which has been fixed by proper gdt
-alignment in the initial boot loader. If you still cannot get your
-voyager system to boot, email me at:
-
-<J.E.J.Bottomley@HansenPartnership.com>
-
-
-The Quad cards now support using the separate Quad CPI vectors instead
-of going through the VIC mailbox system.
-
-The Level 4 architecture (3430 and 3360 Machines) should also work
-fine.
-
-Dump Switch
------------
-
-The voyager dump switch sends out a broadcast NMI which the voyager
-code intercepts and does a task dump.
-
-Power Switch
-------------
-
-The front panel power switch is intercepted by the kernel and should
-cause a system shutdown and power off.
-
-A Note About Mixed CPU Systems
-------------------------------
-
-Linux isn't designed to handle mixed CPU systems very well. In order
-to get everything going you *must* make sure that your lowest
-capability CPU is used for booting. Also, mixing CPU classes
-(e.g. 486 and 586) is really not going to work very well at all.

- bool "Support for hot-pluggable device"

- Say Y here if you want to plug devices into your computer while
- the system is running, and be able to use them quickly. In many
- cases, the devices can likewise be unplugged at any time too.
-
- One well known example of this is PCMCIA- or PC-cards, credit-card
- size devices such as network cards, modems or hard drives which are
- plugged into slots found on all modern laptop computers. Another
- example, used on modern desktops as well as laptops, is USB.
-
- Enable HOTPLUG and build a modular kernel. Get agent software
- (from <http://linux-hotplug.sourceforge.net/>) and install it.
- Then your kernel will automatically call out to a user mode "policy
- agent" (/sbin/hotplug) to load modules and set up software needed
- to use devices as you hotplug them.

+ *
+ * This function will parse the "ranges" property of a PCI host bridge device

+ * content.
+ *
+ * Life would be boring if it wasn't for a few issues that we have to deal
+ * with here:
+ *
+ * - We can only cope with one IO space range and up to 3 Memory space
+ * ranges. However, some machines (thanks Apple !) tend to split their
+ * space into lots of small contiguous ranges. So we have to coalesce.
+ *
+ * - We can only cope with all memory ranges having the same offset
+ * between CPU addresses and PCI addresses. Unfortunately, some bridges
+ * are setup for a large 1:1 mapping along with a small "window" which
+ * maps PCI address 0 to some arbitrary high address of the CPU space in
+ * order to give access to the ISA memory hole.
+ * The way out of here that I've chosen for now is to always set the
+ * offset based on the first resource found, then override it if we
+ * have a different offset and the previous was set by an ISA hole.
+ *
+ * - Some busses have IO space not starting at 0, which causes trouble with
+ * the way we do our IO resource renumbering. The code somewhat deals with
+ * it for 64 bits but I would expect problems on 32 bits.
+ *
+ * - Some 32 bits platforms such as 4xx can have physical space larger than
+ * 32 bits so we need to use 64 bits values for the parsing

+ * Note:
+ * Langwell is the south complex of Intel Moorestown MID platform. There are
+ * eight external timers in total that can be used by the operating system.
+ * The timer information, such as frequency and addresses, is provided to the
+ * OS via SFI tables.
+ * Timer interrupts are routed via FW/HW emulated IOAPIC independently via
+ * individual redirection table entries (RTE).
+ * Unlike HPET, there is no master counter, therefore one of the timers are
+ * used as clocksource. The overall allocation looks like:
+ * - timer 0 - NR_CPUs for per cpu timer
+ * - one timer for clocksource
+ * - one timer for watchdog driver.
+ * It is also worth notice that APB timer does not support true one-shot mode,
+ * free-running mode will be used here to emulate one-shot mode.
+ * APB timer can also be used as broadcast timer along with per cpu local APIC
+ * timer, but by default APB timer has higher rating than local APIC timers.

+ *
+ * Moorestown has an interesting PCI implementation:
+ * - configuration space is memory mapped (as defined by MCFG)
+ * - Lincroft devices also have a real, type 1 configuration space
+ * - Early Lincroft silicon has a type 1 access bug that will cause
+ * a hang if non-existent devices are accessed
+ * - some devices have the "fixed BAR" capability, which means
+ * they can't be relocated or modified; check for that during
+ * BAR sizing
+ *
+ * So, we use the MCFG space for all reads and writes, but also send
+ * Lincroft writes to type 1 space. But only read/write if the device
+ * actually exists, otherwise return all 1s for reads and bit bucket
+ * the writes.

config UEVENT_HELPER_PATH
string "path to uevent helper"
depends on HOTPLUG
- default "/sbin/hotplug"
+ default ""
help
Path to uevent helper program forked by the kernel for
every uevent.
+ Before the switch to the netlink-based uevent source, this was
+ used to hook hotplug scripts into kernel device events. It
+ usually pointed to a shell script at /sbin/hotplug.
+ This should not be used today, because usual systems create
+ many events at bootup or device discovery in a very short time
+ frame. One forked process per event can create so many processes
+ that it creates a high system load, or on smaller systems
+ it is known to create out-of-memory situations during bootup.
config DEVTMPFS
- bool "Create a kernel maintained /dev tmpfs (EXPERIMENTAL)"
+ bool "Maintain a devtmpfs filesystem to mount at /dev"
depends on HOTPLUG && SHMEM && TMPFS
help
- This creates a tmpfs filesystem, and mounts it at bootup
- and mounts it at /dev. The kernel driver core creates device
- nodes for all registered devices in that filesystem. All device
- nodes are owned by root and have the default mode of 0600.
- Userspace can add and delete the nodes as needed. This is
- intended to simplify bootup, and make it possible to delay
- the initial coldplug at bootup done by udev in userspace.
- It should also provide a simpler way for rescue systems
- to bring up a kernel with dynamic major/minor numbers.
- Meaningful symlinks, permissions and device ownership must
- still be handled by userspace.
- If unsure, say N here.
+ This creates a tmpfs filesystem instance early at bootup.
+ In this filesystem, the kernel driver core maintains device
+ nodes with their default names and permissions for all
+ registered devices with an assigned major/minor number.
+ Userspace can modify the filesystem content as needed, add
+ symlinks, and apply needed permissions.
+ It provides a fully functional /dev directory, where usually
+ udev runs on top, managing permissions and adding meaningful
+ symlinks.
+ In very limited environments, it may provide a sufficient
+ functional /dev without any further help. It also allows simple
+ rescue systems, and reliably handles dynamic major/minor numbers.
config DEVTMPFS_MOUNT
- bool "Automount devtmpfs at /dev"
+ bool "Automount devtmpfs at /dev, after the kernel mounted the rootfs"
depends on DEVTMPFS
help
- This will mount devtmpfs at /dev if the kernel mounts the root
- filesystem. It will not affect initramfs based mounting.
- If unsure, say N here.
+ This will instruct the kernel to automatically mount the
+ devtmpfs filesystem at /dev, directly after the kernel has
+ mounted the root filesystem. The behavior can be overridden
+ with the commandline parameter: devtmpfs.mount=0|1.
+ This option does not affect initramfs based booting, here
+ the devtmpfs filesystem always needs to be mounted manually
+ after the roots is mounted.
+ With this option enabled, it allows to bring up a system in
+ rescue mode with init=/bin/sh, even when the /dev directory
+ on the rootfs is completely empty.

- * serial.c (get_pci_port): Deal with awkward Titan cards.
-
-1998-08-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
-
- * serial.c (rs_open): Correctly decrement the module in-use count
- on errors.
-
-Thu Feb 19 14:24:08 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
-
- * tty_io.c (tty_name): Remove the non-reentrant (and non-SMP safe)
- version of tty_name, and rename the reentrant _tty_name
- function to be tty_name.
- (tty_open): Add a warning message stating callout devices
- are deprecated.
-
-Mon Dec 1 08:24:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
-
- * tty_io.c (tty_get_baud_rate): Print a warning syslog if the
- tty->alt_speed kludge is used; this means the system is
- using the deprecated SPD_HI ioctls.
-
-Mon Nov 24 10:37:49 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
-
- * serial.c, esp.c, rocket.c: Change drivers to take advantage of
- tty_get_baud_rate().
-
- * tty_io.c (tty_get_baud_rate): New function which computes the
- correct baud rate for the tty. More factoring out of
- common code out of the serial driver to the high-level tty
- functions....
-
-Sat Nov 22 07:53:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
-
- * serial.c, esp.c, rocket.c: Add tty->driver.break() routine, and
- allow high-level tty code to handle the break and soft
- carrier ioctls.
-
- * tty_ioctl.c (n_tty_ioctl): Support TIOCGSOFTCAR and
- TIOCSSOFTCAR, so that device drivers don't have to support
- it.
-
- * serial.c (autoconfig): Change 16750 test to hopefully eliminate
- false results by people with strange 16550As being
- detected as 16750s. Hopefully 16750s will still be
- detected as 16750, and other weird UARTs won't get poorly
- autodetected. If this doesn't work, I'll have to disable
- the auto identification for the 16750.
-
- * tty_io.c (tty_hangup): Now actually do the tty hangup
- processing during the timer processing, and disable
- interrupts while doing the hangup processing. This avoids
- several nasty race conditions which happened when the
- hangup processing was done asynchronously.
- (tty_ioctl): Do break handling in the tty driver if
- driver's break function is supported.
- (tty_flip_buffer_push): New exported function which should
- be used by drivers to push characters in the flip buffer
- to the tty handler. This may either be done using a task
- queue function for better CPU efficiency, or directly for
- low latency operation.
-
- * serial.c (rs_set_termios): Fix bug rs_set_termios when
- transitioning away from B0, submitted by Stanislav
- Voronyi.
-
-Thu Jun 19 20:05:58 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
-
- * serial.c (begin_break, end_break, rs_ioctl): Applied patch
- to support BSD ioctls to set and clear the break
- condition explicitly.
-
- * console.c (scrup, scrdown, insert_line, delete_line): Applied
- fix suggested by Aaron Tiensivu to speed up block scrolls
- up and down.
-
- * n_tty.c (opost_block, write_chan): Added a modified "fast
- console" patch which processes a block of text via
- "cooking" efficiently.
-
-Wed Jun 18 15:25:50 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
-
- * tty_io.c (init_dev, release_dev): Applied fix suggested by Bill
- Hawes to prevent race conditions in the tty code.
-
- * n_tty.c (n_tty_chars_in_buffer): Applied fix suggested by Bill
- Hawes so that n_tty_chars_in_buffer returns the correct
- value in the case when the tty is in cannonical mode. (To
- avoid a pty deadlock with telnetd.)
-
-Thu Feb 27 01:53:08 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
-
- * serial.c (change_speed): Add support for the termios flag
- CMSPAR, which allows the user to select stick parity.
- (i.e, if PARODD is set, the parity bit is always 1; if
- PARRODD is not set, then the parity bit is always 0).
-
-Wed Feb 26 19:03:10 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
-
- * serial.c (cleanup_module): Fix memory leak when using the serial
- driver as a module; make sure tmp_buf gets freed!
-
-Tue Feb 25 11:01:59 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
-
- * serial.c (set_modem_info): Add support for setting and clearing
- the OUT1 and OUT2 bits. (For special case UART's, usually
- for half-duplex.)
- (autoconfig, change_speed): Fix TI 16750 support.
-
-Sun Feb 16 00:14:43 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
-
- * tty_io.c (release_dev): Add sanity check to make sure there are
- no waiters on tty->read_wait or tty->write_wait.
-
- * serial.c (rs_init): Don't autoconfig a device if the I/O region
- is already reserved.
-
- * serial.c (serial_proc_info): Add support for /proc/serial.
-
-Thu Feb 13 00:49:10 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
-
- * serial.c (receive_chars): When the UART repotrs an overrun
- condition, it does so with a valid character. Changed to
- not throw away the valid character, but instead report the
- overrun after the valid character.
-
- * serial.c: Added new #ifdef's for some of the advanced serial
- driver features. A minimal driver that only supports COM
- 1/2/3/4 without sharing serial interrupts only takes 17k;
- the full driver takes 32k.
-
-Wed Feb 12 14:50:44 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
-
- * vt.c:
- * pty.c:
- * tty_ioctl.c:
- * serial.c: Update routines to use the new 2.1 memory access
- routines.
-
-Wed Dec 4 07:51:52 1996 Theodore Ts'o <tytso@localhost.mit.edu>
-
- * serial.c (change_speed): Use save_flags(); cli() and
- restore_flags() in order to ensure we don't accidentally
- turn on interrupts when starting up the port.
- (startup): Move the insertion of serial structure into the
- IRQ chain earlier into the startup processing. Interrupts
- should be off this whole time, but we eventually will want
- to reduce this window.
-
-Thu Nov 21 10:05:22 1996 Theodore Ts'o <tytso@localhost.mit.edu>
-
- * tty_ioctl.c (tty_wait_until_sent): Always check the driver
- wait_until_ready routine, even if there are no characters
- in the xmit buffer. (There may be charactes in the device
- FIFO.)
- (n_tty_ioctl): Add new flag tty->flow_stopped which
- indicates whether the tty is stopped due to a request by
- the TCXONC ioctl (used by tcflow). If so, don't let an
- incoming XOFF character restart the tty. The tty can only
- be restarted by another TCXONC request.
-
- * tty_io.c (start_tty): Don't allow the tty to be restarted if
- tty->flow_stopped is true.
-
- * n_tty.c (n_tty_receive_char): If tty->flow_stopped is true, and
- IXANY is set, don't eat a character trying to restart the
- tty.
-
- * serial.c (startup): Remove need for MCR_noint from the
- async_struct structure. Only turn on DTR and RTS if the
- baud rate is not zero.
- (change_speed): More accurately calculate the timeout
- value based on the word size. Move responsibility of
- hangup when speed becomes B0 to rs_set_termios()
- (set_serial_info): When changing the UART type set the
- current xmit_fifo_size as well as the permanent
- xmit_fifo_size.
- (rs_ioctl): Fix TCSBRK (used by tcdrain) and TCSBRKP
- ioctls to return EINTR if interrupted by a signal.
- (rs_set_termios): If the baud rate changes to or from B0,
- this function is now responsible for setting or clearing
- DTR and RTS. DTR and RTS are only be changed on the
- transition to or from the B0 state.
- (rs_close): Wait for the characters to drain based on
- info->timeout. At low baud rates (50 bps), it may take a
- long time for the FIFO to completely drain out!
- (rs_wait_until_sent): Fixed timeout handling. Now
- releases control to the scheduler, but checks frequently
- enough so that the function is sensitive enough to pass
- the timing requirements of the NIST-PCTS.
- (block_til_ready): When opening the device, don't turn on
- DTR and RTS if the baud rate is B0.
-
-Thu Nov 14 00:06:09 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
-
- * serial.c (autoconfig): Fix autoconfiguration problems;
- info->flags wasn't getting initialized from the state
- structure. Put in more paranoid test for the 16750.
-
-Fri Nov 8 20:19:50 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
-
- * n_tty.c (n_tty_flush_buffer): Only call driver->unthrottle() if
- the tty was previous throttled.
- (n_tty_set_termios, write_chan): Add changes suggested by
- Simon P. Allen to allow hardware cooking.
-
- * tty_ioctl.c (set_termios): If we get a signal while waiting for
- the tty to drain, return -EINTR.
-
- * serial.c (change_speed): Add support for CREAD, as required by
- POSIX.
-
-Sat Nov 2 20:43:10 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
-
- * serial.c: Wholesale changes. Added support for the Startech
- 16650 and 16650V2 chips. (WARNING: the new startech
- 16650A may or may not work!) Added support for the
- TI16750 (not yet tested). Split async_struct into a
- transient part (async_struct) and a permanent part
- (serial_state) which contains the configuration
- information for the ports. Added new driver routines
- wait_until_sent() and send_xchar() to help with POSIX
- compliance. Added support for radio clocks which waggle
- the carrier detect line (CONFIG_HARD_PPS).
-
- * tty_ioctl.c (tty_wait_until_sent): Added call to new driver
- function tty->driver.wait_until_sent(), which returns when
- the tty's device xmit buffers are drained. Needed for
- full POSIX compliance.
-
- (send_prio_char): New function, called by the ioctl's
- TCIOFF and TCION; uses the new driver call send_xchar(),
- which will send the XON or XOFF character at high priority
- (and even if tty output is stopped).
-
-Wed Jun 5 18:52:04 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
-
- * pty.c (pty_close): When closing a pty, make sure packet mode is
- cleared.
-
-Sun May 26 09:33:52 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
-
- * vesa_blank.c (set_vesa_blanking): Add missing verify_area() call.
-
- * selection.c (set_selection): Add missing verify_area() call.
-
- * tty_io.c (tty_ioctl): Add missing verify_area() calls.
-
- * serial.c (rs_ioctl): Add missing verify_area() calls.
- (rs_init): Allow initialization of serial driver
- configuration from a module.
-
- * random.c (extract_entropy): Add missing verify_area call.
- Don't limit number of characters returned to
- 32,768. Extract entropy is now no longer a inlined
- function.
-
- (random_read): Check return value in case extract_entropy
- returns an error.
-
- (secure_tcp_sequence_number): New function which returns a
- secure TCP sequence number. This is needed to prevent some
- nasty TCP hijacking attacks.
-
- (init_std_data): Initialize using gettimeofday() instead of
- struct timeval xtime.
-
- (fast_add_entropy_word, add_entropy_word): Rename the
- inline function add_entropy_word() to
- fast_add_entropy_word(). Make add_entropy_word() be the
- non-inlined function which is used in non-timing critical
- places, in order to save space.
-
- (initialize_benchmark, begin_benchmark, end_benchmark): New
- functions defined when RANDOM_BENCHMARK is defined. They
- allow us to benchmark the speed of the
- add_timer_randomness() call.
-
- (int_ln, rotate_left): Add two new inline functions with
- i386 optimized asm instructions. This speeds up the
- critical add_entropy_word() and add_timer_randomness()
- functions, which are called from interrupt handlers.
-
-Tue May 7 22:51:11 1996 <tytso@rsts-11.mit.edu>
-
- * random.c (add_timer_randomness): Limit the amount randomness
- that we estimate to 12 bits. (An arbitrary amount).
-
- (extract_entropy): To make it harder to analyze the hash
- function, fold the hash function in half using XOR, and
- use the folded result as the value to emit to the user.
- Also, add timer randomness each pass through the
- exact_entropy call, to increase the amount of unknown
- values during the extraction process.
-
- (random_ioctl): Use IOR/IOW definitions to define the
- ioctl values used by the /dev/random driver. Allow the
- old ioctl values to be used for backwards compatibility
- (for a limited amount of time).
-
-Wed Apr 24 14:02:04 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
-
- * random.c (add_timer_randomness): Use 2nd derivative as well to
- better estimate entropy.
-
- (rand_initialize): Explicitly initialize all the pointers
- to NULL. (Clearing pointers using memset isn't portable.)
- Initialize the random pool with OS-dependent data.
-
- (random_write): Add sanity checking to the arguments to
- random_write(), so that bad arguments won't cause a kernel
- SEGV.
-
- (random_read): Update the access time of the device inode
- when you return data to the user.
-
- (random_ioctl): Wake up the random_wait channel when there
- are only WAIT_INPUT_BITS available. Add more paranoia
- checks to make sure entropy_count doesn't go beyond the
- bounds of (0, POOLSIZE). Add a few missing verify_area
- checks. Add support for the RNDCLEARPOOL ioctl, which
- zaps the random pool.
-
- (add_timer_randomness): Wake up the random_wait
- channel only when there are WAIT_INPUT_BITS available.
-
- (random_select): Allow a random refresh daemon process to
- select on /dev/random for writing; wake up the daemon when
- there are less than WAIT_OUTPUT_BITS bits of randomness
- available.
-
-Tue Apr 23 22:56:07 1996 <tytso@rsts-11.mit.edu>
-
- * tty_io.c (init_dev): Change return code when user attempts to
- open master pty which is already open from EAGAIN to EIO,
- to match with BSD expectations. EIO is more correct
- anyway, since EAGAIN implies that retrying will be
- successful --- which it might be.... Eventually!!
-
- * pty.c (pty_open, pty_close): Fix wait loop so that we don't
- busy loop while waiting for the master side to open.
- Fix tty opening/closing logic. TTY_SLAVE_CLOSED was
- renamed to TTY_OTHER_CLOSED, so that the name is more
- descriptive. Also fixed code so that the tty flag
- actually works correctly now....
-
-Mon Apr 1 10:22:01 1996 <tytso@rsts-11.mit.edu>
-
- * serial.c (rs_close): Cleaned up modularization changes.
- Remove code which forced line discipline back to N_TTY
- this is done in the tty upper layers, and there's no
- reason to do it here. (Making this change also
- removed the requirement that the serial module access
- the internal kernel symbol "ldiscs".)
-
- * tty_io.c (tty_init): Formally register a tty_driver entry for
- /dev/tty (device 4, 0) and /dev/console (device 5, 0).
- This guarantees that major device numbers 4 and 5 will be
- reserved for the tty subsystem (as they have to be because
- of /dev/tty and /dev/console). Removed tty_regdev, as
- this interface is no longer necessary.
-
-Sun Mar 17 20:42:47 GMT 1996 <ah@doc.ic.ac.uk>
-
- * serial.c : modularisation (changes in linux/fs/device.c allow
- kerneld to automatically load the serial module).
-
- * Makefile, Config.in : serial modularisation adds.
-
- * tty_io.c : tty_init_ctty used by to register "cua" driver just
- for the /dev/tty device (5,0). Added tty_regdev.
-
- * serial.c (shutdown, rs_ioctl) : when port shuts down wakeup processes
- waiting on delta_msr_wait. The TIOCMIWAIT ioctl returns EIO
- if no change was done since the time of call.
-
-Sat Mar 16 14:33:13 1996 <aeb@cwi.nl>
-
- * tty_io.c (disassociate_ctty): If disassociate_ctty is called by
- exit, do not perform an implicit vhangup on a pty.
-
-Fri Feb 9 14:15:47 1996 <tytso@rsts-11.mit.edu>
-
- * serial.c (block_til_ready): Fixed another race condition which
- happens if a hangup happens during the open.
-
-Wed Jan 10 10:08:00 1996 <tytso@rsts-11.mit.edu>
-
- * serial.c (block_til_ready): Remove race condition which happened
- if a hangup condition happened during the setup of the
- UART, before rs_open() called block_til_ready(). This
- caused the info->count counter to be erroneously
- decremented.
-
- * serial.c (startup, rs_open): Remove race condition that could
- cause a memory leak of one page. (Fortunately, both race
- conditions were relatively rare in practice.)
-
-Tue Dec 5 13:21:27 1995 <tytso@rsts-11.mit.edu>
-
- * serial.c (check_modem_status, rs_ioctl): Support the new
- ioctl()'s TIOCGICOUNT, TIOCMIWAIT. These allow an
- application program to wait on a modem serial register
- status bit change, and to find out how many changes have
- taken place for the MSR bits.
-
- (rs_write): Eliminate a race condition which is introduced
- if it is necessary to wait for the semaphore.
-
-Sat Nov 4 17:14:45 1995 <tytso@rsts-11.mit.edu>
-
- * tty_io.c (tty_init): Move registration of TTY_MAJOR and
- TTY_AUX_MAJOR to the end, so that /proc/devices looks
- prettier.
-
- * pty.c (pty_init): Use new major numbers for PTY master and slave
- devices. This allow us to have more than 64 pty's. We
- register the old pty devices for backwards compatibility.
- Note that a system should either be using the old pty
- devices or the new pty devices --- in general, it should
- try to use both, since they map into the same pty table.
- The old pty devices are strictly for backwards compatibility.
-
-Wed Oct 11 12:45:24 1995 <tytso@rsts-11.mit.edu>
-
- * tty_io.c (disassociate_ctty): If disassociate_ctty is called by
- exit, perform an implicit vhangup on the tty.
-
- * pty.c (pty_close): When the master pty is closed, send a hangup
- to the slave pty.
- (pty_open): Use the flag TTY_SLAVE_CLOSED to test to see
- if there are any open slave ptys, instead of using
- tty->link->count. The old method got confused if there
- were processes that had hung-up file descriptors on the
- slave tty.
-
-Tue May 2 00:53:25 1995 <tytso@rsx-11.mit.edu>
-
- * tty_io.c (tty_set_ldisc): Wait until the output buffer is
- drained before closing the old line discipline --- needed
- in only one case: XON/XOFF processing.
-
- * n_tty.c (n_tty_close): Don't bother waiting until the output
- driver is closed; in general, the line discipline
- shouldn't care if the hardware is finished
- transmitting before the line discipline terminates.
-
- * tty_io.c (release_dev): Shutdown the line discipline after
- decrementing the tty count variable; but set the
- TTY_CLOSING flag so that we know that this tty structure
- isn't long for this world.
-
- * tty_io.c (init_dev): Add sanity code to check to see if
- TTY_CLOSING is set on a tty structure; if so, something
- bad has happened (probably a line discipline close blocked
- when it shouldn't have; so do a kernel printk and then
- return an error).
-
-Wed Apr 26 10:23:44 1995 Theodore Y. Ts'o <tytso@localhost>
-
- * tty_io.c (release_dev): Try to shutdown the line discipline
- *before* decrementing the tty count variable; this removes
- a potential race condition which occurs when the line
- discipline close blocks, and another process then tries
- open the same serial port.
-
- * serial.c (rs_hangup): When hanging up, flush the output buffer
- before shutting down the UART. Otherwise the line
- discipline close blocks waiting for the characters to get
- flushed, which never happens until the serial port gets reused.
-
-Wed Apr 12 08:06:16 1995 Theodore Y. Ts'o <tytso@localhost>
-
- * serial.c (do_serial_hangup, do_softint, check_modem_status,
- rs_init): Hangups are now scheduled via a separate tqueue
- structure in the async_struct structure, tqueue_hangup.
- This task is pushed on to the tq_schedule queue, so that
- it is processed synchronously by the scheduler.
-
-Sat Feb 18 12:13:51 1995 Theodore Y. Ts'o (tytso@rt-11)
-
- * tty_io.c (disassociate_ctty, tty_open, tty_ioctl): Clear
- current->tty_old_pgrp field when a session leader
- acquires a controlling tty, and after a session leader
- has disassociated from a controlling tty.
-
-Fri Feb 17 09:34:09 1995 Theodore Y. Ts'o (tytso@rt-11)
-
- * serial.c (rs_interrupt_single, rs_interrupt, rs_interrupt_multi):
- Change the number of passes made from 64 to be 256,
- configurable with the #define RS_ISR_PASS_LIMIT.
-
- * serial.c (rs_init, set_serial_info, get_serial_info, rs_close):
- Remove support for closing_wait2. Instead, set
- tty->closing and rely on the line discipline to prevent
- echo wars.
-
- * n_tty.c (n_tty_receive_char): IEXTEN does not need to be
- enabled in order for IXANY to be active.
-
- If tty->closing is set, then only process XON and XOFF
- characters.
-
-Sun Feb 12 23:57:48 1995 Theodore Y. Ts'o (tytso@rt-11)
-
- * serial.c (rs_timer): Change the interrupt poll time from 60
- seconds to 10 seconds, configurable with the #define
- RS_STROBE_TIME.
-
- * serial.c (rs_interrupt_multi, startup, shutdown, rs_ioctl,
- set_multiport_struct, get_multiport_struct): Add
- provisions for a new type of interrupt service routine,
- which better supports multiple serial ports on a single
- IRQ.
-
-Sun Feb 5 19:35:11 1995 Theodore Y. Ts'o (tytso@rt-11)
-
- * tty_ioctl.c (n_tty_ioctl, set_termios, tty_wait_until_sent):
- * serial.c (rs_ioctl, rs_close):
- * cyclades.c (cy_ioctl, cy_close):
- * n_tty.c (n_tty_close): Rename wait_until_sent to
- tty_wait_until_sent, so that it's a better name to export
- in ksyms.c.
-
-Sat Feb 4 23:36:20 1995 Theodore Y. Ts'o (tytso@rt-11)
-
- * serial.c (rs_close): Added missing check for closing_wait2 being
- ASYNC_CLOSING_WAIT_NONE.
-
-Thu Jan 26 09:02:49 1995 Theodore Y. Ts'o (tytso@rt-11)
-
- * serial.c (rs_init, set_serial_info, get_serial_info,
- rs_close): Support close_wait in the serial driver.
- This is helpful for slow devices (like serial
- plotters) so that their outputs don't get flushed upon
- device close. This has to be configurable because
- normally we don't want ports to be hung up for long
- periods of time during a close when they are not
- connected to a device, or the device is powered off.
-
- The default is to wait 30 seconds; in the case of a
- very slow device, the close_wait timeout should be
- lengthened. If it is set to 0, the kernel will wait
- forever for all of the data to be transmitted.
-
-Thu Jan 17 01:17:20 1995 Theodore Y. Ts'o (tytso@rt-11)
-
- * serial.c (startup, change_speed, rs_init): Add support to detect
- the StarTech 16650 chip. Treat it as a 16450 for now,
- because of its FIFO bugs.
-
-Thu Jan 5 21:21:57 1995 <dahinds@users.sourceforge.net>
-
- * serial.c: (receive_char): Added counter to prevent infinite loop
- when a PCMCIA serial device is ejected.
-
-Thu Dec 29 17:53:48 1994 <tytso@rsx-11.mit.edu>
-
- * tty_io.c (check_tty_count): New procedure which checks
- tty->count to make sure that it matches with the number of
- open file descriptors which point at the structure. If
- the number doesn't match, it prints a warning message.
-
-Wed Dec 28 15:41:51 1994 <tytso@rsx-11.mit.edu>
-
- * tty_io.c (do_tty_hangup, disassociate_ctty): At hangup time,
- save the tty's current foreground process group in the
- session leader's task structure. When the session leader
- terminates, send a SIGHUP, SIGCONT to that process group.
- This is not required by POSIX, but it's not prohibited
- either, and it appears to be the least intrusive way
- to fix a problem that dialup servers have with
- orphaned process groups caused by modem hangups.
-
-Thu Dec 8 14:52:11 1994 <tytso@rsx-11.mit.edu>
-
- * serial.c (rs_ioctl): Don't allow most ioctl's if the serial port
- isn't initialized.
-
- * serial.c (rs_close): Don't clear the IER if the serial port
- isn't initialized.
-
- * serial.c (block_til_ready): Don't try to block on the dialin
- port if the serial port isn't initialized.
-
-Wed Dec 7 10:48:30 1994 Si Park (si@wimpol.demon.co.uk)
- * tty_io.c (tty_register_driver): Fix bug when linking onto
- the tty_drivers list. We now test that there are elements
- already on the list before setting the back link from the
- first element to the new driver.
-
- * tty_io.c (tty_unregister_driver): Fix bug in unlinking the
- specified driver from the tty_drivers list. We were not
- setting the back link correctly. This used to result in
- a dangling back link pointer and cause panics on the next
- call to get_tty_driver().
-
-Tue Nov 29 10:21:09 1994 Theodore Y. Ts'o (tytso@rt-11)
-
- * tty_io.c (tty_unregister_driver): Fix bug in
- tty_unregister_driver where the pointer to the refcount is
- tested, instead of the refcount itself. This caused
- tty_unregister_driver to always return EBUSY.
-
-Sat Nov 26 11:59:24 1994 Theodore Y. Ts'o (tytso@rt-11)
-
- * tty_io.c (tty_ioctl): Add support for the new ioctl
- TIOCTTYGSTRUCT, which allow a kernel debugging program
- direct read access to the tty and tty_driver structures.
-
-Fri Nov 25 17:26:22 1994 Theodore Y. Ts'o (tytso@rt-11)
-
- * serial.c (rs_set_termios): Don't wake up processes blocked in
- open when the CLOCAL flag changes, since a blocking
- open only samples the CLOCAL flag once when it blocks,
- and doesn't check it again. (n.b. FreeBSD has a
- different behavior for blocking opens; it's not clear
- whether Linux or FreeBSD's interpretation is correct.
- POSIX doesn't give clear guidance on this issue, so
- this may change in the future....)
-
- * serial.c (block_til_ready): Use the correct termios structure to
- check the CLOCAL flag. If the cuaXX device is active,
- then check the saved termios for the ttySXX device.
- Otherwise, use the currently active termios structure.
-
-Sun Nov 6 21:05:44 1994 Theodore Y. Ts'o (tytso@rt-11)
-
- * serial.c (change_speed): Add support for direct access of
- 57,600 and 115,200 bps.
-
-Wed Nov 2 10:32:36 1994 Theodore Y. Ts'o (tytso@rt-11)
-
- * n_tty.c (n_tty_receive_room): Only allow excess characters
- through if we are in ICANON mode *and* there are other no
- pending lines in the buffer. Otherwise cut and paste over
- 4k breaks.
-
-Sat Oct 29 18:17:34 1994 Theodore Y. Ts'o (tytso@rt-11)
-
- * serial.c (rs_ioctl, get_lsr_info): Added patch suggested by Arne
- Riiber so that user mode programs can tell when the
- transmitter shift register is empty.
-
-Thu Oct 27 23:14:29 1994 Theodore Y. Ts'o (tytso@rt-11)
-
- * tty_ioctl.c (wait_until_sent): Added debugging printk statements
- (under the #ifdef TTY_DEBUG_WAIT_UNTIL_SENT)
-
- * serial.c (rs_interrupt, rs_interrupt_single, receive_chars,
- change_speed, rs_close): rs_close now disables receiver
- interrupts when closing the serial port. This allows the
- serial port to close quickly when Linux and a modem (or a
- mouse) are engaged in an echo war; when closing the serial
- port, we now first stop listening to incoming characters,
- and *then* wait for the transmit buffer to drain.
-
- In order to make this change, the info->read_status_mask
- is now used to control what bits of the line status
- register are looked at in the interrupt routine in all
- cases; previously it was only used in receive_chars to
- select a few of the status bits.
-
-Mon Oct 24 23:36:21 1994 Theodore Y. Ts'o (tytso@rt-11)
-
- * serial.c (rs_close): Add a timeout to the transmitter flush
- loop; this is just a sanity check in case we have flaky
- (or non-existent-but-configured-by-the-user) hardware.
-
-Fri Oct 21 09:37:23 1994 Theodore Y. Ts'o (tytso@rt-11)
-
- * tty_io.c (tty_fasync): When asynchronous I/O is enabled, if the
- process or process group has not be specified yet, set it
- to be the tty's process group, or if that is not yet set,
- to the current process's pid.
-
-Thu Oct 20 23:17:28 1994 Theodore Y. Ts'o (tytso@rt-11)
-
- * n_tty.c (n_tty_receive_room): If we are doing input
- canonicalization, let as many characters through as
- possible, so that the excess characters can be "beeped".
-
-Tue Oct 18 10:02:43 1994 Theodore Y. Ts'o (tytso@rt-11)
-
- * serial.c (rs_start): Removed an incorrect '!' that was
- preventing transmit interrupts from being re-enabled in
- rs_start(). Fortunately in most cases it would be
- re-enabled elsewhere, but this still should be fixed
- correctly.
-
-Sun Oct 9 23:46:03 1994 Theodore Y. Ts'o (tytso@rt-11)
-
- * tty_io.c (do_tty_hangup): If the tty driver flags
- TTY_DRIVER_RESET_TERMIOS is set, then reset the termios
- settings back to the driver's initial configuration. This
- allows the termios settings to be reset even if a process
- has hung up file descriptors keeping a pty's termios from
- being freed and reset.
-
- * tty_io.c (release_dev): Fix memory leak. The pty's other
- termios structure should also be freed.
-
- * serial.c (rs_close, shutdown): Change how we wait for the
- transmitter to completely drain before shutting down the
- serial port. We now do it by scheduling in another
- process instead of busy looping with the interrupts turned
- on. This may eliminate some race condition problems that
- some people seem to be reporting.
-
-Sun Sep 25 14:18:14 1994 Theodore Y. Ts'o (tytso@rt-11)
-
- * tty_io.c (release_dev): When freeing a tty make sure that both
- the tty and the o_tty (if present) aren't a process's
- controlling tty. (Previously, we only checked the tty.)
-
- * serial.c (change_speed): Only enable the Modem Status
- Interrupt for a port if CLOCAL is not set or CRTSCTS
- is set. If we're not checking the carrier detect and
- CTS line, there's no point in enabling the modem
- status interrupt. This will save spurious interrupts
- from slowing down systems who have terminals that
- don't support either line. (Of course, if you want
- only one of CD and CTS support, you will need a
- properly wired serial cable.)
-
-Thu Sep 22 08:32:48 1994 Theodore Y. Ts'o (tytso@rt-11)
-
- * tty_io.c (do_SAK): Return if tty is null.
-
- * tty_io.c (_tty_name): Return "NULL tty" if the passed in tty is
- NULL.
-
-Sat Sep 17 13:19:25 1994 Theodore Y. Ts'o (tytso@rt-11)
-
- * tty_ioctl.c (n_tty_ioctl): Fix TIOCGLCKTRMIOS and
- TIOCSLCKTRMIOS, which were totally broken. Remove
- extra indirection from argument; it should be a struct
- termios *, not a struct termios **.
- &real_tty->termios_locked should have been
- real_tty->termios_locked. This caused us to be
- reading and writing the termios_locked structure to
- random places in kernel memory.
-
- * tty_io.c (release_dev): Oops! Forgot to delete a critical kfree
- of the locked_termios. This leaves the locked_termios
- structure pointed at a freed object.
-
-Fri Sep 16 08:13:25 1994 Theodore Y. Ts'o (tytso@rt-11)
-
- * tty_io.c (tty_open): Don't check for an exclusive open until
- after the device specific open routine has been called.
- Otherwise, the serial device ref counting will be screwed
- up.
-
- * serial.c (rs_open, block_til_ready): Don't set termios structure
- until after block_til_ready has returned successfully.
- Modify block_til_ready to check the normal_termios
- structure directly, so it doesn't rely on termios being
- set before it's called.
-
-Thu Sep 15 23:34:01 1994 Theodore Y. Ts'o (tytso@rt-11)
-
- * serial.c (rs_close): Turn off interrupts during rs_close() to
- prevent a race condition with the hangup code (which
- runs during a software interrupt).
-
- * tty_io.c (release_dev): Don't free the locked_termios structure;
- its state must be retained across device opens.
-
-
- * tty_io.c (tty_unregister_driver): Added function to unregister a
- tty driver. (For loadable device drivers.)

- * The Maxim's MAX7301 device is an SPI driven GPIO expander. There are

- * details
- * Note:
- * - DIN must be stable at the rising edge of clock.
- * - when writing:
- * - always clock in 16 clocks at once
- * - at DIN: D15 first, D0 last
- * - D0..D7 = databyte, D8..D14 = commandbyte
- * - D15 = low -> write command
- * - when reading
- * - always clock in 16 clocks at once
- * - at DIN: D15 first, D0 last
- * - D0..D7 = dummy, D8..D14 = register address
- * - D15 = high -> read command
- * - raise CS and assert it again
- * - always clock in 16 clocks at once
- * - at DOUT: D15 first, D0 last
- * - D0..D7 contains the data from the first cycle
- *
- * The driver exports a standard gpiochip interface
+ * Check max730x.c for further details.

+ * The Maxim MAX7300/1 device is an I2C/SPI driven GPIO expander. There are
+ * 28 GPIOs. 8 of them can trigger an interrupt. See datasheet for more
+ * details
+ * Note:
+ * - DIN must be stable at the rising edge of clock.
+ * - when writing:
+ * - always clock in 16 clocks at once
+ * - at DIN: D15 first, D0 last
+ * - D0..D7 = databyte, D8..D14 = commandbyte
+ * - D15 = low -> write command
+ * - when reading
+ * - always clock in 16 clocks at once
+ * - at DIN: D15 first, D0 last
+ * - D0..D7 = dummy, D8..D14 = register address
+ * - D15 = high -> read command
+ * - raise CS and assert it again
+ * - always clock in 16 clocks at once
+ * - at DOUT: D15 first, D0 last
+ * - D0..D7 contains the data from the first cycle
+ *
+ * The driver exports a standard gpiochip interface

+ * This code deals with PGRAPH contexts on NV50 family cards. Like NV40, it's
+ * the GPU itself that does context-switching, but it needs a special
+ * microcode to do it. And it's the driver's task to supply this microcode,
+ * further known as ctxprog, as well as the initial context values, known
+ * as ctxvals.
+ *
+ * Without ctxprog, you cannot switch contexts. Not even in software, since
+ * the majority of context [xfer strands] isn't accessible directly. You're
+ * stuck with a single channel, and you also suffer all the problems resulting
+ * from missing ctxvals, since you cannot load them.
+ *
+ * Without ctxvals, you're stuck with PGRAPH's default context. It's enough to
+ * run 2d operations, but trying to utilise 3d or CUDA will just lock you up,
+ * since you don't have... some sort of needed setup.
+ *
+ * Nouveau will just disable acceleration if not given ctxprog + ctxvals, since
+ * it's too much hassle to handle no-ctxprog as a special case.
+ */
+
+/*
+ * How ctxprogs work.
+ *
+ * The ctxprog is written in its own kind of microcode, with very small and
+ * crappy set of available commands. You upload it to a small [512 insns]
+ * area of memory on PGRAPH, and it'll be run when PFIFO wants PGRAPH to
+ * switch channel. or when the driver explicitely requests it. Stuff visible
+ * to ctxprog consists of: PGRAPH MMIO registers, PGRAPH context strands,
+ * the per-channel context save area in VRAM [known as ctxvals or grctx],
+ * 4 flags registers, a scratch register, two grctx pointers, plus many
+ * random poorly-understood details.
+ *
+ * When ctxprog runs, it's supposed to check what operations are asked of it,
+ * save old context if requested, optionally reset PGRAPH and switch to the
+ * new channel, and load the new context. Context consists of three major
+ * parts: subset of MMIO registers and two "xfer areas".

+ * xfer areas. These are a pain.
+ *
+ * There are 2 xfer areas: the first one is big and contains all sorts of
+ * stuff, the second is small and contains some per-TP context.
+ *
+ * Each area is split into 8 "strands". The areas, when saved to grctx,
+ * are made of 8-word blocks. Each block contains a single word from
+ * each strand. The strands are independent of each other, their
+ * addresses are unrelated to each other, and data in them is closely
+ * packed together. The strand layout varies a bit between cards: here
+ * and there, a single word is thrown out in the middle and the whole
+ * strand is offset by a bit from corresponding one on another chipset.
+ * For this reason, addresses of stuff in strands are almost useless.
+ * Knowing sequence of stuff and size of gaps between them is much more
+ * useful, and that's how we build the strands in our generator.
+ *
+ * NVA0 takes this mess to a whole new level by cutting the old strands
+ * into a few dozen pieces [known as genes], rearranging them randomly,
+ * and putting them back together to make new strands. Hopefully these
+ * genes correspond more or less directly to the same PGRAPH subunits
+ * as in 400040 register.
+ *
+ * The most common value in default context is 0, and when the genes
+ * are separated by 0's, gene bounduaries are quite speculative...
+ * some of them can be clearly deduced, others can be guessed, and yet
+ * others won't be resolved without figuring out the real meaning of
+ * given ctxval. For the same reason, ending point of each strand
+ * is unknown. Except for strand 0, which is the longest strand and
+ * its end corresponds to end of the whole xfer.
+ *
+ * An unsolved mystery is the seek instruction: it takes an argument
+ * in bits 8-18, and that argument is clearly the place in strands to
+ * seek to... but the offsets don't seem to correspond to offsets as
+ * seen in grctx. Perhaps there's another, real, not randomly-changing
+ * addressing in strands, and the xfer insn just happens to skip over
+ * the unused bits? NV10-NV30 PIPE comes to mind...
+ *
+ * As far as I know, there's no way to access the xfer areas directly
+ * without the help of ctxprog.

+ *
+ * This is the function called by the generic kernel i2c_transfer()

+ * semaphore set in the kernel i2c_transfer() function.
+ *
+ * NOTE:
+ * READ TRANSFER : We impose a restriction of the first message to be the
+ * index message for any read transaction.
+ * - a no index is coded as '0',
+ * - 2byte big endian index is coded as '3'
+ * !!! msg[0].buf holds the actual index.
+ * This is compatible with generic messages of smbus emulator
+ * that send a one byte index.
+ * eg. a I2C transation to read 2 bytes from index 0
+ * idx = 0;
+ * msg[0].addr = client->addr;
+ * msg[0].flags = 0x0;

+ * i2c_transfer(adap, msg, 2);
+ *
+ * WRITE TRANSFER : The I2C standard interface interprets all data as payload.
+ * If you want to emulate an SMBUS write transaction put the
+ * index as first byte(or first and second) in the payload.
+ * eg. a I2C transation to write 2 bytes from index 1
+ * wr_buff[0] = 0x1;
+ * wr_buff[1] = 0x23;
+ * wr_buff[2] = 0x46;

+ * msg[0].len = 3;
+ * msg[0].buf = wr_buff;

* CYPRESS CY82C693 chipset IDE controller
*
* The CY82C693 chipset is used on Digital's PC-Alpha 164SX boards.
- * Writing the driver was quite simple, since most of the job is
- * done by the generic pci-ide support.
- * The hard part was finding the CY82C693's datasheet on Cypress's
- * web page :-(. But Altavista solved this problem :-).
- *
- *
- * Notes:
- * - I recently got a 16.8G IBM DTTA, so I was able to test it with
- * a large and fast disk - the results look great, so I'd say the
- * driver is working fine :-)
- * hdparm -t reports 8.17 MB/sec at about 6% CPU usage for the DTTA
- * - this is my first linux driver, so there's probably a lot of room
- * for optimizations and bug fixing, so feel free to do it.
- * - if using PIO mode it's a good idea to set the PIO mode and
- * 32-bit I/O support (if possible), e.g. hdparm -p2 -c1 /dev/hda
- * - I had some problems with my IBM DHEA with PIO modes < 2
- * (lost interrupts) ?????
- * - first tests with DMA look okay, they seem to work, but there is a
- * problem with sound - the BusMaster IDE TimeOut should fixed this
- *
- * Ancient History:
- * AMH@1999-08-24: v0.34 init_cy82c693_chip moved to pci_init_cy82c693
- * ASK@1999-01-23: v0.33 made a few minor code clean ups
- * removed DMA clock speed setting by default
- * added boot message
- * ASK@1998-11-01: v0.32 added support to set BusMaster IDE TimeOut
- * added support to set DMA Controller Clock Speed
- * ASK@1998-10-31: v0.31 fixed problem with setting to high DMA modes
- * on some drives.
- * ASK@1998-10-29: v0.3 added support to set DMA modes
- * ASK@1998-10-28: v0.2 added support to set PIO modes
- * ASK@1998-10-27: v0.1 first version - chipset detection
- *

* Jan Harkes <jaharkes@cwi.nl>,

* Some parts of code are from ali14xx.c and from rz1000.c.
- *
- * OPTi is trademark of OPTi, Octek is trademark of Octek.
- *
- * I used docs from OPTi databook, from ftp.opti.com, file 9123-0002.ps
- * and disassembled/traced setupvic.exe (DOS program).
- * It increases kernel code about 2 kB.
- * I don't have this card no more, but I hope I can get some in case
- * of needed development.
- * My card is Octek PIDE 1.01 (on card) or OPTiViC (program).
- * It has a place for a secondary connector in circuit, but nothing
- * is there. Also BIOS says no address for
- * secondary controller (see bellow in ide_init_opti621).
- * I've only tested this on my system, which only has one disk.
- * It's Western Digital WDAC2850, with PIO mode 3. The PCI bus
- * is at 20 MHz (I have DX2/80, I tried PCI at 40, but I got random
- * lockups). I tried the OCTEK double speed CD-ROM and
- * it does not work! But I can't boot DOS also, so it's probably
- * hardware fault. I have connected Conner 80MB, the Seagate 850MB (no
- * problems) and Seagate 1GB (as slave, WD as master). My experiences
- * with the third, 1GB drive: I got 3MB/s (hdparm), but sometimes
- * it slows to about 100kB/s! I don't know why and I have
- * not this drive now, so I can't try it again.
- * I write this driver because I lost the paper ("manual") with
- * settings of jumpers on the card and I have to boot Linux with
- * Loadlin except LILO, cause I have to run the setupvic.exe program
- * already or I get disk errors (my test: rpm -Vf
- * /usr/X11R6/bin/XF86_SVGA - or any big file).
- * Some numbers from hdparm -t /dev/hda:
- * Timing buffer-cache reads: 32 MB in 3.02 seconds =10.60 MB/sec
- * Timing buffered disk reads: 16 MB in 5.52 seconds = 2.90 MB/sec
- * I have 4 Megs/s before, but I don't know why (maybe changes
- * in hdparm test).
- * After release of 0.1, I got some successful reports, so it might work.
- *
- * The main problem with OPTi is that some timings for master
- * and slave must be the same. For example, if you have master
- * PIO 3 and slave PIO 0, driver have to set some timings of
- * master for PIO 0. Second problem is that opti621_set_pio_mode
- * got only one drive to set, but have to set both drives.
- * This is solved in compute_pios. If you don't set
- * the second drive, compute_pios use ide_get_best_pio_mode
- * for autoselect mode (you can change it to PIO 0, if you want).
- * If you then set the second drive to another PIO, the old value
- * (automatically selected) will be overrided by yours.
- * There is a 25/33MHz switch in configuration
- * register, but driver is written for use at any frequency.

- *
- * Version 0.3, Nov 29, 1997

- * Updates for use with new IDE block driver.
- *

- * Fixed some errors and cleaned the code.

- * This is a conceptually ridiculous driver, but it is required by the way
- * the Ricoh multi-function chips (R5CXXX) work. These chips implement
- * the four main memory card controllers (SD, MMC, MS, xD) and one or both
- * of cardbus or firewire. It happens that they implement SD and MMC
- * support as separate controllers (and PCI functions). The linux SDHCI
- * driver supports MMC cards but the chip detects MMC cards in hardware
- * and directs them to the MMC controller - so the SDHCI driver never sees
- * them. To get around this, we must disable the useless MMC controller.
- * At that point, the SDHCI controller will start seeing them. As a bonus,
- * a detection event occurs immediately, even if the MMC card is already
- * in the reader.
- *
- * It seems to be the case that the relevant PCI registers to deactivate the
- * MMC controller live on PCI function 0, which might be the cardbus controller
- * or the firewire controller, depending on the particular chip in question. As
- * such, it makes what this driver has to do unavoidably ugly. Such is life.

-/* This driver handles only L2TP data frames; control frames are handled by a
- * userspace application.
- *
- * To send data in an L2TP session, userspace opens a PPPoL2TP socket and
- * attaches it to a bound UDP socket with local tunnel_id / session_id and
- * peer tunnel_id / session_id set. Data can then be sent or received using
- * regular socket sendmsg() / recvmsg() calls. Kernel parameters of the socket
- * can be read or modified using ioctl() or [gs]etsockopt() calls.
- *
- * When a PPPoL2TP socket is connected with local and peer session_id values
- * zero, the socket is treated as a special tunnel management socket.
- *
- * Here's example userspace code to create a socket for sending/receiving data
- * over an L2TP session:-
- *
- * struct sockaddr_pppol2tp sax;
- * int fd;
- * int session_fd;
- *
- * fd = socket(AF_PPPOX, SOCK_DGRAM, PX_PROTO_OL2TP);
- *
- * sax.sa_family = AF_PPPOX;
- * sax.sa_protocol = PX_PROTO_OL2TP;
- * sax.pppol2tp.fd = tunnel_fd; // bound UDP socket
- * sax.pppol2tp.addr.sin_addr.s_addr = addr->sin_addr.s_addr;
- * sax.pppol2tp.addr.sin_port = addr->sin_port;
- * sax.pppol2tp.addr.sin_family = AF_INET;
- * sax.pppol2tp.s_tunnel = tunnel_id;
- * sax.pppol2tp.s_session = session_id;
- * sax.pppol2tp.d_tunnel = peer_tunnel_id;
- * sax.pppol2tp.d_session = peer_session_id;
- *
- * session_fd = connect(fd, (struct sockaddr *)&sax, sizeof(sax));
- *
- * A pppd plugin that allows PPP traffic to be carried over L2TP using
- * this driver is available from the OpenL2TP project at
- * http://openl2tp.sourceforge.net.

+ *
+ * These chips implement the four main memory card controllers (SD, MMC, MS, xD)

+ * It seems to be the case that the relevant PCI registers to deactivate the
+ * MMC controller live on PCI function 0, which might be the cardbus controller
+ * or the firewire controller, depending on the particular chip in question
+ *
+ * This has to be done early, because as soon as we disable the MMC controller

-/* Thanks to Axel Alatalo <axel@rubico.se> for fixing sport rx bug. Sometimes
- * sport receives data incorrectly. The following is Axel's words.
- * As EE-191, sport rx samples 3 times of the UART baudrate and takes the
- * middle smaple of every 3 samples as the data bit. For a 8-N-1 UART setting,
- * 30 samples will be required for a byte. If transmitter sends a 1/3 bit short
- * byte due to buadrate drift, then the 30th sample of a byte, this sample is
- * also the third sample of the stop bit, will happens on the immediately
- * following start bit which will be thrown away and missed. Thus since parts
- * of the startbit will be missed and the receiver will begin to drift, the
- * effect accumulates over time until synchronization is lost.
- * If only require 2 samples of the stopbit (by sampling in total 29 samples),
- * then a to short byte as in the case above will be tolerated. Then the 1/3
- * early startbit will trigger a framesync since the last read is complete
- * after only 2/3 stopbit and framesync is active during the last 1/3 looking
- * for a possible early startbit. */

- *
- *
- * Rationale: This driver exercises the chaining DMA read and write engine
- * in the reference design. It is meant as a complementary reference
- * driver that can be used for testing early designs as well as a basis to
- * write your custom driver.
- *
- * Status: Test results from Leon Woestenberg <leon.woestenberg@axon.tv>:
- *
- * Sendero Board w/ Cyclone II EP2C35F672C6N, PX1011A PCIe x1 PHY on a
- * Dell Precision 370 PC, x86, kernel 2.6.20 from Ubuntu 7.04.
- *
- * Sendero Board w/ Cyclone II EP2C35F672C6N, PX1011A PCIe x1 PHY on a
- * Freescale MPC8313E-RDB board, PowerPC, 2.6.24 w/ Freescale patches.
- *
- * Driver tests passed with PCIe Compiler 8.1. With PCIe 8.0 the DMA
- * loopback test had reproducable compare errors. I assume a change
- * in the compiler or reference design, but could not find evidence nor
- * documentation on a change or fix in that direction.
- *
- * The reference design does not have readable locations and thus a
- * dummy read, used to flush PCI posted writes, cannot be performed.

+LOGGING/DEBUGGING
+-----------------
+
+All error messages, warnings and information messages are sent to the
+kernel log. Depending on your operating system distribution this can be
+read in one of a number of ways. Try using the commands: dmesg,
+logread, or looking in the files /var/log/kern.log or
+/var/log/syslog. All batman-adv messages are prefixed with
+"batman-adv:" So to see just these messages try
+
+dmesg | grep batman-adv
+
+When investigating problems with your mesh network it is sometimes
+necessary to see more detail debug messages. This must be enabled when
+compiling the batman-adv module. Use "make menuconfig" and enable the
+option "B.A.T.M.A.N. debugging".
+
+The additional debug output is by default disabled. It can be enabled
+either at kernel module load time or during run time. To enable debug
+output at module load time, add the module parameter debug=<value>.
+<value> can take one of four values.
+
+0 - All debug output disabled
+1 - Enable messages related to routing / flooding / broadcasting
+2 - Enable route or hna added / changed / deleted
+3 - Enable all messages
+
+e.g.
+
+modprobe batman-adv debug=2
+
+will load the module and enable debug messages for when routes or HNAs
+change.
+
+The debug output can also be changed at runtime using the file
+/sys/module/batman-adv/parameters/debug. e.g.
+
+echo 2 > /sys/module/batman-adv/parameters/debug
+
+enables debug messages for when routes or HNAs
+
+The debug output is sent to the kernel logs. So try dmesg, logread etc
+to see the debug messages.

+
+The allocator shown here exploits high memory. This document explains
+how a user can deal with drivers uses this allocator and how a
+programmer can link in the module.
+
+The module is being used by my pxc and pxdrv device drivers (as well as
+other ones), available from ftp.systemy.it/pub/develop and
+ftp.linux.it/pub/People/Rubini
+
+ User's manual
+ =============
+
+
+One of the most compelling problems with any DMA-capable device is the
+allocation of a suitable memory buffer. The "allocator" module tries
+to deal with the problem in a clean way. The module is able to use
+high memory (above the one used in normal operation) for DMA
+allocation.
+
+To prevent the kernel for using high memory, so that it remains
+available for DMA, you should pass a command line argument to the
+kernel. Command line arguments can be passed to Lilo, to Loadlin or
+to whichever loader you are using (unless it's very poor in design).
+For Lilo, either use "append=" in /etc/lilo.conf or add commandline
+arguments to the interactive prompt. For example, I have a 32MB box
+and reserve two megs for DMA:
+
+In lilo.conf:
+ image = /zImage
+ label = linux
+ append = "mem=30M"
+
+Or, interactively:
+ LILO: linux mem=30M
+
+Once the kernel is booted with the right command-line argument, any
+driver linked with the allocator module will be able to get
+DMA-capable memory without much trouble (unless the various drivers
+need more memory than available).
+
+The module implements an alloc/free mechanism, so that it can serve
+multiple drivers at the same time. Note however that the allocator
+uses all of high memory and assumes to be the only piece of software
+using such memory.
+
+
+ Programmer's manual
+ ===================
+
+The allocator, as released, is designed to be linked to a device
+driver. In this case, the driver must call allocator_init() before
+using the allocator and must call allocator_cleanup() before
+unloading. This is usually done from within init_module() and
+cleanup_module(). If the allocator is linked to a driver, it won't be
+possible for several drivers to allocate high DMA memory, as explained
+above.
+
+It is possible, on the other hand, to compile the module as a standalone
+module, so that several modules can rely on the allocator for they DMA
+buffers. To compile the allocator as a standalone module, do the
+following in this directory (or provide a suitable Makefile, or edit
+the source code):
+
+ make allocator.o CC="gcc -Dallocator_init=init_module -Dallocator_cleanup=cleanup_module -include /usr/include/linux/module.h"
+
+The previous commandline tells to include <linux/module.h> in the
+first place, and to rename the init and cleanup function to the ones
+needed for module loading and unloading. Drivers using a standalone
+allocator won't need to call allocator_init() nor allocator_cleanup().
+
+The allocator exports the following functions (declared in allocator.h):
+
+ unsigned long allocator_allocate_dma (unsigned long kilobytes,
+ int priority);
+
+ This function returns a physical address, over high_memory,
+ which corresponds to an area of at least "kilobytes" kilobytes.
+ The area will be owned by the module calling the function.
+ The returned address can be passed to device boards, to instruct
+ their DMA controllers, via phys_to_bus(). The address can be used
+ by C code after vremap()/ioremap(). The "priority" argument should
+ be GFP_KERNEL or GFP_ATOMIC, according to the context of the
+ caller; it is used to call kmalloc(), as the allocator must keep
+ track of any region it gives away. In case of error the function
+ returns 0, and the caller is expected to issue a -ENOMEM error.
+
+
+ void allocator_free_dma (unsigned long address);
+
+ This function is the reverse of the previous one. If a driver
+ doesn't free the DMA memory it allocated, the allocator will
+ consider such memory as busy. Note, however, that
+ allocator_cleanup() calls kfree() on every region it reclaimed,
+ so that a driver with the allocator linked in can avoid calling
+ allocator_free_dma() at unload time.
+

+ 02-Aug-2002 NJC allocator now steps in 1MB increments, rather
+ than doubling its size each time.
+ Also, allocator_init(u32 *) now returns
+ (in the first arg) the size of the free
+ space. This is no longer consistent with
+ using the allocator as a module, and some changes
+ may be necessary for that purpose. This was
+ designed to work with the DT3155 driver, in
+ stand alone mode only!!!
+ 26-Oct-2009 SS Port to 2.6.30 kernel.

+-- Changes --
+
+ Date Programmer Description of changes made
+ -------------------------------------------------------------------
+ 03-Jul-2000 JML n/a
+ 10-Oct-2001 SS port to 2.4 kernel
+ 02-Apr-2002 SS Mods to use allocator as a standalone module;
+ Merged John Roll's changes (john@cfa.harvard.edu)
+ to make work with multiple boards.
+ 02-Jul-2002 SS Merged James Rose's chages (rosejr@purdue.edu) to:
+ * fix successive interrupt-driven captures
+ * add select/poll support.
+ 10-Jul-2002 GCS Add error check when ndevices > MAXBOARDS.
+ 02-Aug-2002 GCS Fix field mode so that odd (lower) field is stored
+ in lower half of buffer.
+ 05-Aug-2005 SS port to 2.6 kernel.
+ 26-Oct-2009 SS port to 2.6.30 kernel.
+
+-- Notes --
+
+** appended "mem=124" in lilo.conf to allow for 4megs free on my 128meg system.
+ * using allocator.c and allocator.h from o'reilly book (alessandro rubini)
+ ftp://ftp.systemy.it/pub/develop (see README.allocator)
+
+ + might want to get rid of MAXboards for allocating initial buffer.
+ confusing and not necessary
+
+ + in cleanup_module the MOD_IN_USE looks like it is check after it should
+
+ * GFP_DMA should not be set with a PCI system (pg 291)
+
+ - NJC why are only two buffers allowed? (see isr, approx line 358)

+ 03-Jul-2000 JML n/a
+ 02-Apr-2002 SS Mods to make work with separate allocator

+ 24-Jul-2002 SS GPL licence.
+ 30-Jul-2002 NJC Added support for buffer loop.
+ 31-Jul-2002 NJC Complete rewrite of buffer management
+ 02-Aug-2002 NJC Including slab.h instead of malloc.h (no warning).
+ Also, allocator_init() now returns allocator_max
+ so cleaned up allocate_buffers() accordingly.
+ 08-Aug-2005 SS port to 2.6 kernel.

+ This driver allows other kernel drivers access to the

+ registers.
+
+ The restricted access region control registers
+ (rar_registers) are used to pass address and
+ locking information on restricted access regions
+ to other drivers that use restricted access regions
+
+ The restricted access regions are regions of memory
+ on the Intel MID Platform that are not accessible to
+ the x86 processor, but are accessible to dedicated
+ processors on board peripheral devices.
+
+ The purpose of the restricted access regions is to
+ protect sensitive data from compromise by unauthorized
+ programs running on the x86 processor.

+ * 3. [15:8]: Register Offset
+ * 4. [7:4]: Byte Enables (use 0xF to set all of these bits

+ * 5. [3:0]: reserved
+ *
+ * Read (0xD0) and write (0xE0) opcodes are written to the
+ * control register when reading and writing to Lincroft
+ * registers, respectively.
+ *
+ * We're interested in registers found in the Lincroft
+ * B-unit. The B-unit port is 0x3.
+ *
+ * The six B-unit RAR register offsets we use are listed
+ * earlier in this file.
+ *
+ * Lastly writing to the MCR register requires the "Byte
+ * enables" bits to be set to 1. This may be achieved by
+ * writing 0xF at bit 4.
+ *
+ * The MDR (message data register) format is the following:
+ * 1. [31:0]: Read/Write Data
+ *
+ * Data being read from this register is only available after
+ * writing the appropriate control message to the MCR

- This is an experimental driver for DisplayLink USB devices
- that provides a framebuffer device. A normal framebuffer can
- be used with this driver, or xorg can be run on the device
- using it.
+ This is a kernel framebuffer driver for DisplayLink USB devices.
+ Supports fbdev clients like xf86-video-fbdev, kdrive, fbi, and
+ mplayer -vo fbdev. Supports all USB 2.0 era DisplayLink devices.
+ To compile as a module, choose M here: the module name is udlfb.

-Thanks to Henrik Bjerregaard Pedersen for rle implementation and code refactoring.
-Next step is huffman compression.
+Render a command stream for an encoded horizontal line segment of pixels.
+
+A command buffer holds several commands.
+It always begins with a fresh command header
+(the protocol doesn't require this, but we enforce it to allow
+multiple buffers to be potentially encoded and sent in parallel).
+A single command encodes one contiguous horizontal line of pixels
+
+The function relies on the client to do all allocation, so that
+rendering can be done directly to output buffers (e.g. USB URBs).
+The function fills the supplied command buffer, providing information
+on where it left off, so the client may call in again with additional
+buffers if the line will take several buffers to complete.
+
+A single command can transmit a maximum of 256 pixels,
+regardless of the compression ratio (protocol design limit).
+To the hardware, 0 for a size byte means 256
+
+Rather than 256 pixel commands which are either rl or raw encoded,
+the rlx command simply assumes alternating raw and rl spans within one cmd.
+This has a slightly larger header overhead, but produces more even results.
+It also processes all data (read and write) in a single pass.
+Performance benchmarks of common cases show it having just slightly better
+compression than 256 pixel raw -or- rle commands, with similar CPU consumpion.
+But for very rl friendly data, will compress not quite as well.

+ * The i.MX21 USB hardware contains
+ * * 32 transfer descriptors (called ETDs)
+ * * 4Kb of Data memory
+ *
+ * The data memory is shared between the host and fuction controlers
+ * (but this driver only supports the host controler)
+ *
+ * So setting up a transfer involves:
+ * * Allocating a ETD
+ * * Fill in ETD with appropriate information
+ * * Allocating data memory (and putting the offset in the ETD)
+ * * Activate the ETD
+ * * Get interrupt when done.
+ *
+ * An ETD is assigned to each active endpoint.
+ *
+ * Low resource (ETD and Data memory) situations are handled differently for
+ * isochronous and non insosynchronous transactions :
+ *
+ * Non ISOC transfers are queued if either ETDs or Data memory are unavailable
+ *
+ * ISOC transfers use 2 ETDs per endpoint to achieve double buffering.
+ * They allocate both ETDs and Data memory during URB submission
+ * (and fail if unavailable).

+ * Ceph address space ops.

+ * There are a few funny things going on here.
+ *
+ * The page->private field is used to reference a struct
+ * ceph_snap_context for _every_ dirty page. This indicates which
+ * snapshot the page was logically dirtied in, and thus which snap
+ * context needs to be associated with the osd write during writeback.
+ *
+ * Similarly, struct ceph_inode_info maintains a set of counters to
+ * count dirty pages on the inode. In the absense of snapshots,
+ * i_wrbuffer_ref == i_wrbuffer_ref_head == the dirty page count.
+ *
+ * When a snapshot is taken (that is, when the client receives
+ * notification that a snapshot was taken), each inode with caps and
+ * with dirty pages (dirty pages implies there is a cap) gets a new
+ * ceph_cap_snap in the i_cap_snaps list (which is sorted in ascending
+ * order, new snaps go to the tail). The i_wrbuffer_ref_head count is
+ * moved to capsnap->dirty. (Unless a sync write is currently in
+ * progress. In that case, the capsnap is said to be "pending", new
+ * writes cannot start, and the capsnap isn't "finalized" until the

+ * mtime), note its dirty state in the ceph_cap, and asynchronously
+ * flush that metadata change to the MDS.
+ *
+ * In the event of a conflicting operation (perhaps by another
+ * client), the MDS will revoke the conflicting client capabilities.
+ *
+ * In order for a client to cache an inode, it must hold a capability

+ * conditions at unexpected times. We take use a few different
+ * strategies:
+ *
+ * - for request/response type interactions, we preallocate the
+ * memory needed for the response when we generate the request.
+ *
+ * - for messages we can receive at any time from the MDS, we preallocate
+ * a pool of messages we can re-use.
+ *
+ * - for writeback, we preallocate some number of messages to use for
+ * requests and their replies, so that we always make forward
+ * progress.
+ *
+ * The msgpool behaves like a mempool_t, but keeps preallocated
+ * ceph_msgs strung together on a list_head instead of using a pointer
+ * vector. This avoids vector reallocation when we adjust the number
+ * of preallocated items (which happens frequently).

+ * Snapshots in ceph are driven in large part by cooperation from the
+ * client. In contrast to local file systems or file servers that
+ * implement snapshots at a single point in the system, ceph's
+ * distributed access to storage requires clients to help decide
+ * whether a write logically occurs before or after a recently created
+ * snapshot.
+ *
+ * This provides a perfect instantanous client-wide snapshot. Between
+ * clients, however, snapshots may appear to be applied at slightly
+ * different points in time, depending on delays in delivering the
+ * snapshot notification.
+ *
+ * Snapshots are _not_ file system-wide. Instead, each snapshot
+ * applies to the subdirectory nested beneath some directory. This
+ * effectively divides the hierarchy into multiple "realms," where all
+ * of the files contained by each realm share the same set of
+ * snapshots. An individual realm's snap set contains snapshots
+ * explicitly created on that realm, as well as any snaps in its
+ * parent's snap set _after_ the point at which the parent became it's
+ * parent (due to, say, a rename). Similarly, snaps from prior parents
+ * during the time intervals during which they were the parent are included.
+ *
+ * The client is spared most of this detail, fortunately... it must only
+ * maintains a hierarchy of realms reflecting the current parent/child
+ * realm relationship, and for each realm has an explicit list of snaps
+ * inherited from prior parents.
+ *
+ * A snap_realm struct is maintained for realms containing every inode
+ * with an open cap in the system. (The needed snap realm information is
+ * provided by the MDS whenever a cap is issued, i.e., on open.) A 'seq'
+ * version number is used to ensure that as realm parameters change (new
+ * snapshot, new parent, etc.) the client's realm hierarchy is updated.
+ *
+ * The realm hierarchy drives the generation of a 'snap context' for each
+ * realm, which simply lists the resulting set of snaps for the realm. This
+ * is attached to any writes sent to OSDs.
+ */

+ * Atomic dir operations
+ *
+ * Directory operations are by default not atomic. Dentries and Inodes are
+ * created/removed/altered in seperate operations. Therefore we need to do
+ * a small amount of journaling.
+ *
+ * Create, link, mkdir, mknod and symlink all share the same function to do
+ * the work: __logfs_create. This function works in two atomic steps:
+ * 1. allocate inode (remember in journal)
+ * 2. allocate dentry (clear journal)
+ *
+ * As we can only get interrupted between the two, when the inode we just
+ * created is simply stored in the anchor. On next mount, if we were
+ * interrupted, we delete the inode. From a users point of view the
+ * operation never happened.
+ *
+ * Unlink and rmdir also share the same function: unlink. Again, this
+ * function works in two atomic steps
+ * 1. remove dentry (remember inode in journal)
+ * 2. unlink inode (clear journal)
+ *
+ * And again, on the next mount, if we were interrupted, we delete the inode.
+ * From a users point of view the operation succeeded.
+ *
+ * Rename is the real pain to deal with, harder than all the other methods
+ * combined. Depending on the circumstances we can run into three cases.
+ * A "target rename" where the target dentry already existed, a "local
+ * rename" where both parent directories are identical or a "cross-directory
+ * rename" in the remaining case.
+ *
+ * Local rename is atomic, as the old dentry is simply rewritten with a new
+ * name.
+ *
+ * Cross-directory rename works in two steps, similar to __logfs_create and
+ * logfs_unlink:
+ * 1. Write new dentry (remember old dentry in journal)
+ * 2. Remove old dentry (clear journal)
+ *
+ * Here we remember a dentry instead of an inode. On next mount, if we were
+ * interrupted, we delete the dentry. From a users point of view, the
+ * operation succeeded.
+ *
+ * Target rename works in three atomic steps:
+ * 1. Attach old inode to new dentry (remember old dentry and new inode)
+ * 2. Remove old dentry (still remember the new inode)
+ * 3. Remove victim inode
+ *
+ * Here we remember both an inode an a dentry. If we get interrupted
+ * between steps 1 and 2, we delete both the dentry and the inode. If
+ * we get interrupted between steps 2 and 3, we delete just the inode.
+ * In either case, the remaining objects are deleted on next mount. From
+ * a users point of view, the operation succeeded.

+ * to overflow the 32bit name space or nfs and 32bit host systems will

+ *
+ * So we use the following scheme. First we reduce the hash to 0..15

+ *
+ * Using 16 entries should allow for a reasonable amount of hash
+ * collisions, so the 32bit name space can be packed fairly tight
+ * before overflowing. Oh and currently we don't overflow but return
+ * and error.
+ *
+ * How likely are collisions? Doing the appropriate math is beyond me
+ * and the Bronstein textbook. But running a test program to brute
+ * force collisions for a couple of days showed that on average the

+ * So we cannot just call iget() or some variant of it, but first have to check

+ * Also, inodes have logfs-specific reference counting on top of what the vfs

+ * to zero and the inode gets deleted. But if GC accessed the inode, its
+ * refcount will remain nonzero and final deletion will have to wait.
+ *

-ToDo/Notes:
- - Find and fix bugs.
- - The only places in the kernel where a file is resized are
- ntfs_file_write*() and ntfs_truncate() for both of which i_mutex is
- held. Just have to be careful in read-/writepage and other helpers
- not running under i_mutex that we play nice. Also need to be careful
- with initialized_size extension in ntfs_file_write*() and writepage.
- UPDATE: The only things that need to be checked are the compressed
- write and the other attribute resize/write cases like index
- attributes, etc. For now none of these are implemented so are safe.
- - Implement filling in of holes in aops.c::ntfs_writepage() and its
- helpers.
- - Implement mft.c::sync_mft_mirror_umount(). We currently will just
- leave the volume dirty on umount if the final iput(vol->mft_ino)
- causes a write of any mirrored mft records due to the mft mirror
- inode having been discarded already. Whether this can actually ever
- happen is unclear however so it is worth waiting until someone hits
- the problem.
-
-2.1.29 - Fix a deadlock at mount time.
-
- - During mount the VFS holds s_umount lock on the superblock. So when
- we try to empty the journal $LogFile contents by calling
- ntfs_attr_set() when the machine does not have much memory and the
- journal is large ntfs_attr_set() results in the VM trying to balance
- dirty pages which in turn tries to that the s_umount lock and thus we
- get a deadlock. The solution is to not use ntfs_attr_set() and
- instead do the zeroing by hand at the block level rather than page
- cache level.
- - Fix sparse warnings.
-
-2.1.28 - Fix a deadlock.
-
- - Fix deadlock in fs/ntfs/inode.c::ntfs_put_inode(). Thanks to Sergey
- Vlasov for the report and detailed analysis of the deadlock. The fix
- involved getting rid of ntfs_put_inode() altogether and hence NTFS no
- longer has a ->put_inode super operation.
-
-2.1.27 - Various bug fixes and cleanups.
-
- - Fix two compiler warnings on Alpha. Thanks to Andrew Morton for
- reporting them.
- - Fix an (innocent) off-by-one error in the runlist code.
- - Fix a buggette in an "should be impossible" case handling where we
- continued the attribute lookup loop instead of aborting it.
- - Use buffer_migrate_page() for the ->migratepage function of all ntfs
- address space operations.
- - Fix comparison of $MFT and $MFTMirr to not bail out when there are
- unused, invalid mft records which are the same in both $MFT and
- $MFTMirr.
- - Add support for sparse files which have a compression unit of 0.
- - Remove all the make_bad_inode() calls. This should only be called
- from read inode and new inode code paths.
- - Limit name length in fs/ntfs/unistr.c::ntfs_nlstoucs() to maximum
- allowed by NTFS, i.e. 255 Unicode characters, not including the
- terminating NULL (which is not stored on disk).
- - Improve comments on file attribute flags in fs/ntfs/layout.h.
- - Fix a bug in fs/ntfs/inode.c::ntfs_read_locked_index_inode() where we
- forgot to update a temporary variable so loading index inodes which
- have an index allocation attribute failed.
- - Add a missing call to flush_dcache_mft_record_page() in
- fs/ntfs/inode.c::ntfs_write_inode().
- - Handle the recently introduced -ENAMETOOLONG return value from
- fs/ntfs/unistr.c::ntfs_nlstoucs() in fs/ntfs/namei.c::ntfs_lookup().
- - Semaphore to mutex conversion. (Ingo Molnar)
-
-2.1.26 - Minor bug fixes and updates.
-
- - Fix a potential overflow in file.c where a cast to s64 was missing in
- a left shift of a page index.
- - The struct inode has had its i_sem semaphore changed to a mutex named
- i_mutex.
- - We have struct kmem_cache now so use it instead of the typedef
- kmem_cache_t. (Pekka Enberg)
- - Implement support for sector sizes above 512 bytes (up to the maximum
- supported by NTFS which is 4096 bytes).
- - Do more detailed reporting of why we cannot mount read-write by
- special casing the VOLUME_MODIFIED_BY_CHKDSK flag.
- - Miscellaneous updates to layout.h.
- - Cope with attribute list attribute having invalid flags. Windows
- copes with this and even chkdsk does not detect or fix this so we
- have to cope with it, too. Thanks to Pawel Kot for reporting the
- problem.
-
-2.1.25 - (Almost) fully implement write(2) and truncate(2).
-
- - Change ntfs_map_runlist_nolock(), ntfs_attr_find_vcn_nolock() and
- {__,}ntfs_cluster_free() to also take an optional attribute search
- context as argument. This allows calling these functions with the
- mft record mapped. Update all callers.
- - Fix potential deadlock in ntfs_mft_data_extend_allocation_nolock()
- error handling by passing in the active search context when calling
- ntfs_cluster_free().
- - Change ntfs_cluster_alloc() to take an extra boolean parameter
- specifying whether the cluster are being allocated to extend an
- attribute or to fill a hole.
- - Change ntfs_attr_make_non_resident() to call ntfs_cluster_alloc()
- with @is_extension set to TRUE and remove the runlist terminator
- fixup code as this is now done by ntfs_cluster_alloc().
- - Change ntfs_attr_make_non_resident to take the attribute value size
- as an extra parameter. This is needed since we need to know the size
- before we can map the mft record and our callers always know it. The
- reason we cannot simply read the size from the vfs inode i_size is
- that this is not necessarily uptodate. This happens when
- ntfs_attr_make_non_resident() is called in the ->truncate call path.
- - Fix ntfs_attr_make_non_resident() to update the vfs inode i_blocks
- which is zero for a resident attribute but should no longer be zero
- once the attribute is non-resident as it then has real clusters
- allocated.
- - Add fs/ntfs/attrib.[hc]::ntfs_attr_extend_allocation(), a function to
- extend the allocation of an attributes. Optionally, the data size,
- but not the initialized size can be extended, too.
- - Implement fs/ntfs/inode.[hc]::ntfs_truncate(). It only supports
- uncompressed and unencrypted files and it never creates sparse files
- at least for the moment (making a file sparse requires us to modify
- its directory entries and we do not support directory operations at
- the moment). Also, support for highly fragmented files, i.e. ones
- whose data attribute is split across multiple extents, is severly
- limited. When such a case is encountered, EOPNOTSUPP is returned.
- - Enable ATTR_SIZE attribute changes in ntfs_setattr(). This completes
- the initial implementation of file truncation. Now both open(2)ing
- a file with the O_TRUNC flag and the {,f}truncate(2) system calls
- will resize a file appropriately. The limitations are that only
- uncompressed and unencrypted files are supported. Also, there is
- only very limited support for highly fragmented files (the ones whose
- $DATA attribute is split into multiple attribute extents).
- - In attrib.c::ntfs_attr_set() call balance_dirty_pages_ratelimited()
- and cond_resched() in the main loop as we could be dirtying a lot of
- pages and this ensures we play nice with the VM and the system as a
- whole.
- - Implement file operations ->write, ->aio_write, ->writev for regular
- files. This replaces the old use of generic_file_write(), et al and
- the address space operations ->prepare_write and ->commit_write.
- This means that both sparse and non-sparse (unencrypted and
- uncompressed) files can now be extended using the normal write(2)
- code path. There are two limitations at present and these are that
- we never create sparse files and that we only have limited support
- for highly fragmented files, i.e. ones whose data attribute is split
- across multiple extents. When such a case is encountered,
- EOPNOTSUPP is returned.
- - $EA attributes can be both resident and non-resident.
- - Use %z for size_t to fix compilation warnings. (Andrew Morton)
- - Fix compilation warnings with gcc-4.0.2 on SUSE 10.0.
- - Document extended attribute ($EA) NEED_EA flag. (Based on libntfs
- patch by Yura Pakhuchiy.)
-
-2.1.24 - Lots of bug fixes and support more clean journal states.
-
- - Support journals ($LogFile) which have been modified by chkdsk. This
- means users can boot into Windows after we marked the volume dirty.
- The Windows boot will run chkdsk and then reboot. The user can then
- immediately boot into Linux rather than having to do a full Windows
- boot first before rebooting into Linux and we will recognize such a
- journal and empty it as it is clean by definition. Note, this only
- works if chkdsk left the journal in an obviously clean state.
- - Support journals ($LogFile) with only one restart page as well as
- journals with two different restart pages. We sanity check both and
- either use the only sane one or the more recent one of the two in the
- case that both are valid.
- - Add fs/ntfs/malloc.h::ntfs_malloc_nofs_nofail() which is analogous to
- ntfs_malloc_nofs() but it performs allocations with __GFP_NOFAIL and
- hence cannot fail.
- - Use ntfs_malloc_nofs_nofail() in the two critical regions in
- fs/ntfs/runlist.c::ntfs_runlists_merge(). This means we no longer
- need to panic() if the allocation fails as it now cannot fail.
- - Fix two nasty runlist merging bugs that had gone unnoticed so far.
- Thanks to Stefano Picerno for the bug report.
- - Remove two bogus BUG_ON()s from fs/ntfs/mft.c.
- - Fix handling of valid but empty mapping pairs array in
- fs/ntfs/runlist.c::ntfs_mapping_pairs_decompress().
- - Report unrepresentable inodes during ntfs_readdir() as KERN_WARNING
- messages and include the inode number. Thanks to Yura Pakhuchiy for
- pointing this out.
- - Change ntfs_rl_truncate_nolock() to throw away the runlist if the new
- length is zero.
- - Add runlist.[hc]::ntfs_rl_punch_nolock() which punches a caller
- specified hole into a runlist.
- - Fix a bug in fs/ntfs/index.c::ntfs_index_lookup(). When the returned
- index entry is in the index root, we forgot to set the @ir pointer in
- the index context. Thanks to Yura Pakhuchiy for finding this bug.
- - Remove bogus setting of PageError in ntfs_read_compressed_block().
- - Add fs/ntfs/attrib.[hc]::ntfs_resident_attr_value_resize().
- - Fix a bug in ntfs_map_runlist_nolock() where we forgot to protect
- access to the allocated size in the ntfs inode with the size lock.
- - Fix ntfs_attr_vcn_to_lcn_nolock() and ntfs_attr_find_vcn_nolock() to
- return LCN_ENOENT when there is no runlist and the allocated size is
- zero.
- - Fix load_attribute_list() to handle the case of a NULL runlist.
- - Fix handling of sparse attributes in ntfs_attr_make_non_resident().
- - Add BUG() checks to ntfs_attr_make_non_resident() and ntfs_attr_set()
- to ensure that these functions are never called for compressed or
- encrypted attributes.
- - Fix cluster (de)allocators to work when the runlist is NULL and more
- importantly to take a locked runlist rather than them locking it
- which leads to lock reversal.
- - Truncate {a,c,m}time to the ntfs supported time granularity when
- updating the times in the inode in ntfs_setattr().
- - Fixup handling of sparse, compressed, and encrypted attributes in
- fs/ntfs/inode.c::ntfs_read_locked_{,attr_,index_}inode(),
- fs/ntfs/aops.c::ntfs_{read,write}page().
- - Make ntfs_write_block() not instantiate sparse blocks if they contain
- only zeroes.
- - Optimize fs/ntfs/aops.c::ntfs_write_block() by extending the page
- lock protection over the buffer submission for i/o which allows the
- removal of the get_bh()/put_bh() pairs for each buffer.
- - Fix fs/ntfs/aops.c::ntfs_{read,write}_block() to handle the case
- where a concurrent truncate has truncated the runlist under our feet.
- - Fix page_has_buffers()/page_buffers() handling in fs/ntfs/aops.c.
- - In fs/ntfs/aops.c::ntfs_end_buffer_async_read(), use a bit spin lock
- in the first buffer head instead of a driver global spin lock to
- improve scalability.
- - Minor fix to error handling and error message display in
- fs/ntfs/aops.c::ntfs_prepare_nonresident_write().
- - Change the mount options {u,f,d}mask to always parse the number as
- an octal number to conform to how chmod(1) works, too. Thanks to
- Giuseppe Bilotta and Horst von Brand for pointing out the errors of
- my ways.
- - Fix various bugs in the runlist merging code. (Based on libntfs
- changes by Richard Russon.)
- - Fix sparse warnings that have crept in over time.
- - Change ntfs_cluster_free() to require a write locked runlist on entry
- since we otherwise get into a lock reversal deadlock if a read locked
- runlist is passed in. In the process also change it to take an ntfs
- inode instead of a vfs inode as parameter.
- - Fix the definition of the CHKD ntfs record magic. It had an off by
- two error causing it to be CHKB instead of CHKD.
- - Fix a stupid bug in __ntfs_bitmap_set_bits_in_run() which caused the
- count to become negative and hence we had a wild memset() scribbling
- all over the system's ram.
-
-2.1.23 - Implement extension of resident files and make writing safe as well as
- many bug fixes, cleanups, and enhancements...
-
- - Add printk rate limiting for ntfs_warning() and ntfs_error() when
- compiled without debug. This avoids a possible denial of service
- attack. Thanks to Carl-Daniel Hailfinger from SuSE for pointing this
- out.
- - Fix compilation warnings on ia64. (Randy Dunlap)
- - Use i_size_{read,write}() instead of reading i_size by hand and cache
- the value where apropriate.
- - Add size_lock to the ntfs_inode structure. This is an rw spinlock
- and it locks against access to the inode sizes. Note, ->size_lock
- is also accessed from irq context so you must use the _irqsave and
- _irqrestore lock and unlock functions, respectively. Protect all
- accesses to allocated_size, initialized_size, and compressed_size.
- - Minor optimization to fs/ntfs/super.c::ntfs_statfs() and its helpers.
- - Implement extension of resident files in the regular file write code
- paths (fs/ntfs/aops.c::ntfs_{prepare,commit}_write()). At present
- this only works until the data attribute becomes too big for the mft
- record after which we abort the write returning -EOPNOTSUPP from
- ntfs_prepare_write().
- - Add disable_sparse mount option together with a per volume sparse
- enable bit which is set appropriately and a per inode sparse disable
- bit which is preset on some system file inodes as appropriate.
- - Enforce that sparse support is disabled on NTFS volumes pre 3.0.
- - Fix a bug in fs/ntfs/runlist.c::ntfs_mapping_pairs_decompress() in
- the creation of the unmapped runlist element for the base attribute
- extent.
- - Split ntfs_map_runlist() into ntfs_map_runlist() and a non-locking
- helper ntfs_map_runlist_nolock() which is used by ntfs_map_runlist().
- This allows us to map runlist fragments with the runlist lock already
- held without having to drop and reacquire it around the call. Adapt
- all callers.
- - Change ntfs_find_vcn() to ntfs_find_vcn_nolock() which takes a locked
- runlist. This allows us to find runlist elements with the runlist
- lock already held without having to drop and reacquire it around the
- call. Adapt all callers.
- - Change time to u64 in time.h::ntfs2utc() as it otherwise generates a
- warning in the do_div() call on sparc32. Thanks to Meelis Roos for
- the report and analysis of the warning.
- - Fix a nasty runlist merge bug when merging two holes.
- - Set the ntfs_inode->allocated_size to the real allocated size in the
- mft record for resident attributes (fs/ntfs/inode.c).
- - Small readability cleanup to use "a" instead of "ctx->attr"
- everywhere (fs/ntfs/inode.c).
- - Make fs/ntfs/namei.c::ntfs_get_{parent,dentry} static and move the
- definition of ntfs_export_ops from fs/ntfs/super.c to namei.c. Also,
- declare ntfs_export_ops in fs/ntfs/ntfs.h.
- - Correct sparse file handling. The compressed values need to be
- checked and set in the ntfs inode as done for compressed files and
- the compressed size needs to be used for vfs inode->i_blocks instead
- of the allocated size, again, as done for compressed files.
- - Add AT_EA in addition to AT_DATA to whitelist for being allowed to be
- non-resident in fs/ntfs/attrib.c::ntfs_attr_can_be_non_resident().
- - Add fs/ntfs/attrib.c::ntfs_attr_vcn_to_lcn_nolock() used by the new
- write code.
- - Fix bug in fs/ntfs/attrib.c::ntfs_find_vcn_nolock() where after
- dropping the read lock and taking the write lock we were not checking
- whether someone else did not already do the work we wanted to do.
- - Rename fs/ntfs/attrib.c::ntfs_find_vcn_nolock() to
- ntfs_attr_find_vcn_nolock() and update all callers.
- - Add fs/ntfs/attrib.[hc]::ntfs_attr_make_non_resident().
- - Fix sign of various error return values to be negative in
- fs/ntfs/lcnalloc.c.
- - Modify ->readpage and ->writepage (fs/ntfs/aops.c) so they detect and
- handle the case where an attribute is converted from resident to
- non-resident by a concurrent file write.
- - Remove checks for NULL before calling kfree() since kfree() does the
- checking itself. (Jesper Juhl)
- - Some utilities modify the boot sector but do not update the checksum.
- Thus, relax the checking in fs/ntfs/super.c::is_boot_sector_ntfs() to
- only emit a warning when the checksum is incorrect rather than
- refusing the mount. Thanks to Bernd Casimir for pointing this
- problem out.
- - Update attribute definition handling.
- - Add NTFS_MAX_CLUSTER_SIZE and NTFS_MAX_PAGES_PER_CLUSTER constants.
- - Use NTFS_MAX_CLUSTER_SIZE in super.c instead of hard coding 0x10000.
- - Use MAX_BUF_PER_PAGE instead of variable sized array allocation for
- better code generation and one less sparse warning in fs/ntfs/aops.c.
- - Remove spurious void pointer casts from fs/ntfs/. (Pekka Enberg)
- - Use C99 style structure initialization after memory allocation where
- possible (fs/ntfs/{attrib.c,index.c,super.c}). Thanks to Al Viro and
- Pekka Enberg.
- - Stamp the transaction log ($UsnJrnl), aka user space journal, if it
- is active on the volume and we are mounting read-write or remounting
- from read-only to read-write.
- - Fix a bug in address space operations error recovery code paths where
- if the runlist was not mapped at all and a mapping error occured we
- would leave the runlist locked on exit to the function so that the
- next access to the same file would try to take the lock and deadlock.
- - Detect the case when Windows has been suspended to disk on the volume
- to be mounted and if this is the case do not allow (re)mounting
- read-write. This is done by parsing hiberfil.sys if present.
- - Fix several occurences of a bug where we would perform 'var & ~const'
- with a 64-bit variable and a int, i.e. 32-bit, constant. This causes
- the higher order 32-bits of the 64-bit variable to be zeroed. To fix
- this cast the 'const' to the same 64-bit type as 'var'.
- - Change the runlist terminator of the newly allocated cluster(s) to
- LCN_ENOENT in ntfs_attr_make_non_resident(). Otherwise the runlist
- code gets confused.
- - Add an extra parameter @last_vcn to ntfs_get_size_for_mapping_pairs()
- and ntfs_mapping_pairs_build() to allow the runlist encoding to be
- partial which is desirable when filling holes in sparse attributes.
- Update all callers.
- - Change ntfs_map_runlist_nolock() to only decompress the mapping pairs
- if the requested vcn is inside it. Otherwise we get into problems
- when we try to map an out of bounds vcn because we then try to map
- the already mapped runlist fragment which causes
- ntfs_mapping_pairs_decompress() to fail and return error. Update
- ntfs_attr_find_vcn_nolock() accordingly.
- - Fix a nasty deadlock that appeared in recent kernels.
- The situation: VFS inode X on a mounted ntfs volume is dirty. For
- same inode X, the ntfs_inode is dirty and thus corresponding on-disk
- inode, i.e. mft record, which is in a dirty PAGE_CACHE_PAGE belonging
- to the table of inodes, i.e. $MFT, inode 0.
- What happens:
- Process 1: sys_sync()/umount()/whatever... calls
- __sync_single_inode() for $MFT -> do_writepages() -> write_page for
- the dirty page containing the on-disk inode X, the page is now locked
- -> ntfs_write_mst_block() which clears PageUptodate() on the page to
- prevent anyone else getting hold of it whilst it does the write out.
- This is necessary as the on-disk inode needs "fixups" applied before
- the write to disk which are removed again after the write and
- PageUptodate is then set again. It then analyses the page looking
- for dirty on-disk inodes and when it finds one it calls
- ntfs_may_write_mft_record() to see if it is safe to write this
- on-disk inode. This then calls ilookup5() to check if the
- corresponding VFS inode is in icache(). This in turn calls ifind()
- which waits on the inode lock via wait_on_inode whilst holding the
- global inode_lock.
- Process 2: pdflush results in a call to __sync_single_inode for the
- same VFS inode X on the ntfs volume. This locks the inode (I_LOCK)
- then calls write-inode -> ntfs_write_inode -> map_mft_record() ->
- read_cache_page() for the page (in page cache of table of inodes
- $MFT, inode 0) containing the on-disk inode. This page has
- PageUptodate() clear because of Process 1 (see above) so
- read_cache_page() blocks when it tries to take the page lock for the
- page so it can call ntfs_read_page().
- Thus Process 1 is holding the page lock on the page containing the
- on-disk inode X and it is waiting on the inode X to be unlocked in
- ifind() so it can write the page out and then unlock the page.
- And Process 2 is holding the inode lock on inode X and is waiting for
- the page to be unlocked so it can call ntfs_readpage() or discover
- that Process 1 set PageUptodate() again and use the page.
- Thus we have a deadlock due to ifind() waiting on the inode lock.
- The solution: The fix is to use the newly introduced
- ilookup5_nowait() which does not wait on the inode's lock and hence
- avoids the deadlock. This is safe as we do not care about the VFS
- inode and only use the fact that it is in the VFS inode cache and the
- fact that the vfs and ntfs inodes are one struct in memory to find
- the ntfs inode in memory if present. Also, the ntfs inode has its
- own locking so it does not matter if the vfs inode is locked.
- - Fix bug in mft record writing where we forgot to set the device in
- the buffers when mapping them after the VM had discarded them.
- Thanks to Martin MOKREJÅ for the bug report.
-
-2.1.22 - Many bug and race fixes and error handling improvements.
-
- - Improve error handling in fs/ntfs/inode.c::ntfs_truncate().
- - Change fs/ntfs/inode.c::ntfs_truncate() to return an error code
- instead of void and provide a helper ntfs_truncate_vfs() for the
- vfs ->truncate method.
- - Add a new ntfs inode flag NInoTruncateFailed() and modify
- fs/ntfs/inode.c::ntfs_truncate() to set and clear it appropriately.
- - Fix min_size and max_size definitions in ATTR_DEF structure in
- fs/ntfs/layout.h to be signed.
- - Add attribute definition handling helpers to fs/ntfs/attrib.[hc]:
- ntfs_attr_size_bounds_check(), ntfs_attr_can_be_non_resident(), and
- ntfs_attr_can_be_resident(), which in turn use the new private helper
- ntfs_attr_find_in_attrdef().
- - In fs/ntfs/aops.c::mark_ntfs_record_dirty(), take the
- mapping->private_lock around the dirtying of the buffer heads
- analagous to the way it is done in __set_page_dirty_buffers().
- - Ensure the mft record size does not exceed the PAGE_CACHE_SIZE at
- mount time as this cannot work with the current implementation.
- - Check for location of attribute name and improve error handling in
- general in fs/ntfs/inode.c::ntfs_read_locked_inode() and friends.
- - In fs/ntfs/aops.c::ntfs_writepage(), if the page is fully outside
- i_size, i.e. race with truncate, invalidate the buffers on the page
- so that they become freeable and hence the page does not leak.
- - Remove unused function fs/ntfs/runlist.c::ntfs_rl_merge(). (Adrian
- Bunk)
- - Fix stupid bug in fs/ntfs/attrib.c::ntfs_attr_find() that resulted in
- a NULL pointer dereference in the error code path when a corrupt
- attribute was found. (Thanks to Domen Puncer for the bug report.)
- - Add MODULE_VERSION() to fs/ntfs/super.c.
- - Make several functions and variables static. (Adrian Bunk)
- - Modify fs/ntfs/aops.c::mark_ntfs_record_dirty() so it allocates
- buffers for the page if they are not present and then marks the
- buffers belonging to the ntfs record dirty. This causes the buffers
- to become busy and hence they are safe from removal until the page
- has been written out.
- - Fix stupid bug in fs/ntfs/attrib.c::ntfs_external_attr_find() in the
- error handling code path that resulted in a BUG() due to trying to
- unmap an extent mft record when the mapping of it had failed and it
- thus was not mapped. (Thanks to Ken MacFerrin for the bug report.)
- - Drop the runlist lock after the vcn has been read in
- fs/ntfs/lcnalloc.c::__ntfs_cluster_free().
- - Rewrite handling of multi sector transfer errors. We now do not set
- PageError() when such errors are detected in the async i/o handler
- fs/ntfs/aops.c::ntfs_end_buffer_async_read(). All users of mst
- protected attributes now check the magic of each ntfs record as they
- use it and act appropriately. This has the effect of making errors
- granular per ntfs record rather than per page which solves the case
- where we cannot access any of the ntfs records in a page when a
- single one of them had an mst error. (Thanks to Ken MacFerrin for
- the bug report.)
- - Fix error handling in fs/ntfs/quota.c::ntfs_mark_quotas_out_of_date()
- where we failed to release i_mutex on the $Quota/$Q attribute inode.
- - Fix bug in handling of bad inodes in fs/ntfs/namei.c::ntfs_lookup().
- - Add mapping of unmapped buffers to all remaining code paths, i.e.
- fs/ntfs/aops.c::ntfs_write_mst_block(), mft.c::ntfs_sync_mft_mirror(),
- and write_mft_record_nolock(). From now on we require that the
- complete runlist for the mft mirror is always mapped into memory.
- - Add creation of buffers to fs/ntfs/mft.c::ntfs_sync_mft_mirror().
- - Improve error handling in fs/ntfs/aops.c::ntfs_{read,write}_block().
- - Cleanup fs/ntfs/aops.c::ntfs_{read,write}page() since we know that a
- resident attribute will be smaller than a page which makes the code
- simpler. Also make the code more tolerant to concurrent ->truncate.
-
-2.1.21 - Fix some races and bugs, rewrite mft write code, add mft allocator.
-
- - Implement extent mft record deallocation
- fs/ntfs/mft.c::ntfs_extent_mft_record_free().
- - Splitt runlist related functions off from attrib.[hc] to runlist.[hc].
- - Add vol->mft_data_pos and initialize it at mount time.
- - Rename init_runlist() to ntfs_init_runlist(), ntfs_vcn_to_lcn() to
- ntfs_rl_vcn_to_lcn(), decompress_mapping_pairs() to
- ntfs_mapping_pairs_decompress(), ntfs_merge_runlists() to
- ntfs_runlists_merge() and adapt all callers.
- - Add fs/ntfs/runlist.[hc]::ntfs_get_nr_significant_bytes(),
- ntfs_get_size_for_mapping_pairs(), ntfs_write_significant_bytes(),
- and ntfs_mapping_pairs_build(), adapted from libntfs.
- - Make fs/ntfs/lcnalloc.c::ntfs_cluster_free_from_rl_nolock() not
- static and add a declaration for it to lcnalloc.h.
- - Add fs/ntfs/lcnalloc.h::ntfs_cluster_free_from_rl() which is a static
- inline wrapper for ntfs_cluster_free_from_rl_nolock() which takes the
- cluster bitmap lock for the duration of the call.
- - Add fs/ntfs/attrib.[hc]::ntfs_attr_record_resize().
- - Implement the equivalent of memset() for an ntfs attribute in
- fs/ntfs/attrib.[hc]::ntfs_attr_set() and switch
- fs/ntfs/logfile.c::ntfs_empty_logfile() to using it.
- - Remove unnecessary casts from LCN_* constants.
- - Implement fs/ntfs/runlist.c::ntfs_rl_truncate_nolock().
- - Add MFT_RECORD_OLD as a copy of MFT_RECORD in fs/ntfs/layout.h and
- change MFT_RECORD to contain the NTFS 3.1+ specific fields.
- - Add a helper function fs/ntfs/aops.c::mark_ntfs_record_dirty() which
- marks all buffers belonging to an ntfs record dirty, followed by
- marking the page the ntfs record is in dirty and also marking the vfs
- inode containing the ntfs record dirty (I_DIRTY_PAGES).
- - Switch fs/ntfs/index.h::ntfs_index_entry_mark_dirty() to using the
- new helper fs/ntfs/aops.c::mark_ntfs_record_dirty() and remove the no
- longer needed fs/ntfs/index.[hc]::__ntfs_index_entry_mark_dirty().
- - Move ntfs_{un,}map_page() from ntfs.h to aops.h and fix resulting
- include errors.
- - Move the typedefs for runlist_element and runlist from types.h to
- runlist.h and fix resulting include errors.
- - Remove unused {__,}format_mft_record() from fs/ntfs/mft.c.
- - Modify fs/ntfs/mft.c::__mark_mft_record_dirty() to use the helper
- mark_ntfs_record_dirty() which also changes the behaviour in that we
- now set the buffers belonging to the mft record dirty as well as the
- page itself.
- - Update fs/ntfs/mft.c::write_mft_record_nolock() and sync_mft_mirror()
- to cope with the fact that there now are dirty buffers in mft pages.
- - Update fs/ntfs/inode.c::ntfs_write_inode() to also use the helper
- mark_ntfs_record_dirty() and thus to set the buffers belonging to the
- mft record dirty as well as the page itself.
- - Fix compiler warnings on x86-64 in fs/ntfs/dir.c. (Randy Dunlap,
- slightly modified by me)
- - Add fs/ntfs/mft.c::try_map_mft_record() which fails with -EALREADY if
- the mft record is already locked and otherwise behaves the same way
- as fs/ntfs/mft.c::map_mft_record().
- - Modify fs/ntfs/mft.c::write_mft_record_nolock() so that it only
- writes the mft record if the buffers belonging to it are dirty.
- Otherwise we assume that it was written out by other means already.
- - Attempting to write outside initialized size is _not_ a bug so remove
- the bug check from fs/ntfs/aops.c::ntfs_write_mst_block(). It is in
- fact required to write outside initialized size when preparing to
- extend the initialized size.
- - Map the page instead of using page_address() before writing to it in
- fs/ntfs/aops.c::ntfs_mft_writepage().
- - Provide exclusion between opening an inode / mapping an mft record
- and accessing the mft record in fs/ntfs/mft.c::ntfs_mft_writepage()
- by setting the page not uptodate throughout ntfs_mft_writepage().
- - Clear the page uptodate flag in fs/ntfs/aops.c::ntfs_write_mst_block()
- to ensure noone can see the page whilst the mst fixups are applied.
- - Add the helper fs/ntfs/mft.c::ntfs_may_write_mft_record() which
- checks if an mft record may be written out safely obtaining any
- necessary locks in the process. This is used by
- fs/ntfs/aops.c::ntfs_write_mst_block().
- - Modify fs/ntfs/aops.c::ntfs_write_mst_block() to also work for
- writing mft records and improve its error handling in the process.
- Now if any of the records in the page fail to be written out, all
- other records will be written out instead of aborting completely.
- - Remove ntfs_mft_aops and update all users to use ntfs_mst_aops.
- - Modify fs/ntfs/inode.c::ntfs_read_locked_inode() to set the
- ntfs_mst_aops for all inodes which are NInoMstProtected() and
- ntfs_aops for all other inodes.
- - Rename fs/ntfs/mft.c::sync_mft_mirror{,_umount}() to
- ntfs_sync_mft_mirror{,_umount}() and change their parameters so they
- no longer require an ntfs inode to be present. Update all callers.
- - Cleanup the error handling in fs/ntfs/mft.c::ntfs_sync_mft_mirror().
- - Clear the page uptodate flag in fs/ntfs/mft.c::ntfs_sync_mft_mirror()
- to ensure noone can see the page whilst the mst fixups are applied.
- - Remove the no longer needed fs/ntfs/mft.c::ntfs_mft_writepage() and
- fs/ntfs/mft.c::try_map_mft_record().
- - Fix callers of fs/ntfs/aops.c::mark_ntfs_record_dirty() to call it
- with the ntfs inode which contains the page rather than the ntfs
- inode the mft record of which is in the page.
- - Fix race condition in fs/ntfs/inode.c::ntfs_put_inode() by moving the
- index inode bitmap inode release code from there to
- fs/ntfs/inode.c::ntfs_clear_big_inode(). (Thanks to Christoph
- Hellwig for spotting this.)
- - Fix race condition in fs/ntfs/inode.c::ntfs_put_inode() by taking the
- inode semaphore around the code that sets ni->itype.index.bmp_ino to
- NULL and reorganize the code to optimize it a bit. (Thanks to
- Christoph Hellwig for spotting this.)
- - Modify fs/ntfs/aops.c::mark_ntfs_record_dirty() to no longer take the
- ntfs inode as a parameter as this is confusing and misleading and the
- needed ntfs inode is available via NTFS_I(page->mapping->host).
- Adapt all callers to this change.
- - Modify fs/ntfs/mft.c::write_mft_record_nolock() and
- fs/ntfs/aops.c::ntfs_write_mst_block() to only check the dirty state
- of the first buffer in a record and to take this as the ntfs record
- dirty state. We cannot look at the dirty state for subsequent
- buffers because we might be racing with
- fs/ntfs/aops.c::mark_ntfs_record_dirty().
- - Move the static inline ntfs_init_big_inode() from fs/ntfs/inode.c to
- inode.h and make fs/ntfs/inode.c::__ntfs_init_inode() non-static and
- add a declaration for it to inode.h. Fix some compilation issues
- that resulted due to #includes and header file interdependencies.
- - Simplify setup of i_mode in fs/ntfs/inode.c::ntfs_read_locked_inode().
- - Add helpers fs/ntfs/layout.h::MK_MREF() and MK_LE_MREF().
- - Modify fs/ntfs/mft.c::map_extent_mft_record() to only verify the mft
- record sequence number if it is specified (i.e. not zero).
- - Add fs/ntfs/mft.[hc]::ntfs_mft_record_alloc() and various helper
- functions used by it.
- - Update Documentation/filesystems/ntfs.txt with instructions on how to
- use the Device-Mapper driver with NTFS ftdisk/LDM raid. This removes
- the linear raid problem with the Software RAID / MD driver when one
- or more of the devices has an odd number of sectors.
-
-2.1.20 - Fix two stupid bugs introduced in 2.1.18 release.
-
- - Fix stupid bug in fs/ntfs/attrib.c::ntfs_attr_reinit_search_ctx()
- where we did not clear ctx->al_entry but it was still set due to
- changes in ntfs_attr_lookup() and ntfs_external_attr_find() in
- particular.
- - Fix another stupid bug in fs/ntfs/attrib.c::ntfs_external_attr_find()
- where we forgot to unmap the extent mft record when we had finished
- enumerating an attribute which caused a bug check to trigger when the
- VFS calls ->clear_inode.
-
-2.1.19 - Many cleanups, improvements, and a minor bug fix.
-
- - Update ->setattr (fs/ntfs/inode.c::ntfs_setattr()) to refuse to
- change the uid, gid, and mode of an inode as we do not support NTFS
- ACLs yet.
- - Remove BKL use from ntfs_setattr() syncing up with the rest of the
- kernel.
- - Get rid of the ugly transparent union in fs/ntfs/dir.c::ntfs_readdir()
- and ntfs_filldir() as per suggestion from Al Viro.
- - Change '\0' and L'\0' to simply 0 as per advice from Linus Torvalds.
- - Update ->truncate (fs/ntfs/inode.c::ntfs_truncate()) to check if the
- inode size has changed and to only output an error if so.
- - Rename fs/ntfs/attrib.h::attribute_value_length() to ntfs_attr_size().
- - Add le{16,32,64} as well as sle{16,32,64} data types to
- fs/ntfs/types.h.
- - Change ntfschar to be le16 instead of u16 in fs/ntfs/types.h.
- - Add le versions of VCN, LCN, and LSN called leVCN, leLCN, and leLSN,
- respectively, to fs/ntfs/types.h.
- - Update endianness conversion macros in fs/ntfs/endian.h to use the
- new types as appropriate.
- - Do proper type casting when using sle64_to_cpup() in fs/ntfs/dir.c
- and index.c.
- - Add leMFT_REF data type to fs/ntfs/layout.h.
- - Update all NTFS header files with the new little endian data types.
- Affected files are fs/ntfs/layout.h, logfile.h, and time.h.
- - Do proper type casting when using ntfs_is_*_recordp() in
- fs/ntfs/logfile.c, mft.c, and super.c.
- - Fix all the sparse bitwise warnings. Had to change all the typedef
- enums storing little endian values to simple enums plus a typedef for
- the datatype to make sparse happy.
- - Fix a bug found by the new sparse bitwise warnings where the default
- upcase table was defined as a pointer to wchar_t rather than ntfschar
- in fs/ntfs/ntfs.h and super.c.
- - Change {const_,}cpu_to_le{16,32}(0) to just 0 as suggested by Al Viro.
-
-2.1.18 - Fix scheduling latencies at mount time as well as an endianness bug.
-
- - Remove vol->nr_mft_records as it was pretty meaningless and optimize
- the calculation of total/free inodes as used by statfs().
- - Fix scheduling latencies in ntfs_fill_super() by dropping the BKL
- because the code itself is using the ntfs_lock semaphore which
- provides safe locking. (Ingo Molnar)
- - Fix a potential bug in fs/ntfs/mft.c::map_extent_mft_record() that
- could occur in the future for when we start closing/freeing extent
- inodes if we don't set base_ni->ext.extent_ntfs_inos to NULL after
- we free it.
- - Rename {find,lookup}_attr() to ntfs_attr_{find,lookup}() as well as
- find_external_attr() to ntfs_external_attr_find() to cleanup the
- namespace a bit and to be more consistent with libntfs.
- - Rename {{re,}init,get,put}_attr_search_ctx() to
- ntfs_attr_{{re,}init,get,put}_search_ctx() as well as the type
- attr_search_context to ntfs_attr_search_ctx.
- - Force use of ntfs_attr_find() in ntfs_attr_lookup() when searching
- for the attribute list attribute itself.
- - Fix endianness bug in ntfs_external_attr_find().
- - Change ntfs_{external_,}attr_find() to return 0 on success, -ENOENT
- if the attribute is not found, and -EIO on real error. In the case
- of -ENOENT, the search context is updated to describe the attribute
- before which the attribute being searched for would need to be
- inserted if such an action were to be desired and in the case of
- ntfs_external_attr_find() the search context is also updated to
- indicate the attribute list entry before which the attribute list
- entry of the attribute being searched for would need to be inserted
- if such an action were to be desired. Also make ntfs_find_attr()
- static and remove its prototype from attrib.h as it is not used
- anywhere other than attrib.c. Update ntfs_attr_lookup() and all
- callers of ntfs_{external,}attr_{find,lookup}() for the new return
- values.
- - Minor cleanup of fs/ntfs/inode.c::ntfs_init_locked_inode().
-
-2.1.17 - Fix bugs in mount time error code paths and other updates.
-
- - Implement bitmap modification code (fs/ntfs/bitmap.[hc]). This
- includes functions to set/clear a single bit or a run of bits.
- - Add fs/ntfs/attrib.[hc]::ntfs_find_vcn() which returns the locked
- runlist element containing a particular vcn. It also takes care of
- mapping any needed runlist fragments.
- - Implement cluster (de-)allocation code (fs/ntfs/lcnalloc.[hc]).
- - Load attribute definition table from $AttrDef at mount time.
- - Fix bugs in mount time error code paths involving (de)allocation of
- the default and volume upcase tables.
- - Remove ntfs_nr_mounts as it is no longer used.
-
-2.1.16 - Implement access time updates, file sync, async io, and read/writev.
-
- - Add support for readv/writev and aio_read/aio_write (fs/ntfs/file.c).
- This is done by setting the appropriate file operations pointers to
- the generic helper functions provided by mm/filemap.c.
- - Implement fsync, fdatasync, and msync both for files (fs/ntfs/file.c)
- and directories (fs/ntfs/dir.c).
- - Add support for {a,m,c}time updates to inode.c::ntfs_write_inode().
- Note, except for the root directory and any other system files opened
- by the user, the system files will not have their access times
- updated as they are only accessed at the inode level an hence the
- file level functions which cause the times to be updated are never
- invoked.
-
-2.1.15 - Invalidate quotas when (re)mounting read-write.
-
- - Add new element itype.index.collation_rule to the ntfs inode
- structure and set it appropriately in ntfs_read_locked_inode().
- - Implement a new inode type "index" to allow efficient access to the
- indices found in various system files and adapt inode handling
- accordingly (fs/ntfs/inode.[hc]). An index inode is essentially an
- attribute inode (NInoAttr() is true) with an attribute type of
- AT_INDEX_ALLOCATION. As such, it is no longer allowed to call
- ntfs_attr_iget() with an attribute type of AT_INDEX_ALLOCATION as
- there would be no way to distinguish between normal attribute inodes
- and index inodes. The function to obtain an index inode is
- ntfs_index_iget() and it uses the helper function
- ntfs_read_locked_index_inode(). Note, we do not overload
- ntfs_attr_iget() as indices consist of multiple attributes so using
- ntfs_attr_iget() to obtain an index inode would be confusing.
- - Ensure that there is no overflow when doing page->index <<
- PAGE_CACHE_SHIFT by casting page->index to s64 in fs/ntfs/aops.c.
- - Use atomic kmap instead of kmap() in fs/ntfs/aops.c::ntfs_read_page()
- and ntfs_read_block().
- - Use case sensitive attribute lookups instead of case insensitive ones.
- - Lock all page cache pages belonging to mst protected attributes while
- accessing them to ensure we never see corrupt data while the page is
- under writeout.
- - Add framework for generic ntfs collation (fs/ntfs/collation.[hc]).
- We have ntfs_is_collation_rule_supported() to check if the collation
- rule you want to use is supported and ntfs_collation() which actually
- collates two data items. We currently only support COLLATION_BINARY
- and COLLATION_NTOFS_ULONG but support for other collation rules will
- be added as the need arises.
- - Add a new type, ntfs_index_context, to allow retrieval of an index
- entry using the corresponding index key. To get an index context,
- use ntfs_index_ctx_get() and to release it, use ntfs_index_ctx_put().
- This also adds a new slab cache for the index contexts. To lookup a
- key in an index inode, use ntfs_index_lookup(). After modifying an
- index entry, call ntfs_index_entry_flush_dcache_page() followed by
- ntfs_index_entry_mark_dirty() to ensure the changes are written out
- to disk. For details see fs/ntfs/index.[hc]. Note, at present, if
- an index entry is in the index allocation attribute rather than the
- index root attribute it will not be written out (you will get a
- warning message about discarded changes instead).
- - Load the quota file ($Quota) and check if quota tracking is enabled
- and if so, mark the quotas out of date. This causes windows to
- rescan the volume on boot and update all quota entries.
- - Add a set_page_dirty address space operation for ntfs_m[fs]t_aops.
- It is simply set to __set_page_dirty_nobuffers() to make sure that
- running set_page_dirty() on a page containing mft/ntfs records will
- not affect the dirty state of the page buffers.
- - Add fs/ntfs/index.c::__ntfs_index_entry_mark_dirty() which sets all
- buffers that are inside the ntfs record in the page dirty after which
- it sets the page dirty. This allows ->writepage to only write the
- dirty index records rather than having to write all the records in
- the page. Modify fs/ntfs/index.h::ntfs_index_entry_mark_dirty() to
- use this rather than __set_page_dirty_nobuffers().
- - Implement fs/ntfs/aops.c::ntfs_write_mst_block() which enables the
- writing of page cache pages belonging to mst protected attributes
- like the index allocation attribute in directory indices and other
- indices like $Quota/$Q, etc. This means that the quota is now marked
- out of date on all volumes rather than only on ones where the quota
- defaults entry is in the index root attribute of the $Quota/$Q index.
-
-2.1.14 - Fix an NFSd caused deadlock reported by several users.
-
- - Modify fs/ntfs/ntfs_readdir() to copy the index root attribute value
- to a buffer so that we can put the search context and unmap the mft
- record before calling the filldir() callback. We need to do this
- because of NFSd which calls ->lookup() from its filldir callback()
- and this causes NTFS to deadlock as ntfs_lookup() maps the mft record
- of the directory and since ntfs_readdir() has got it mapped already
- ntfs_lookup() deadlocks.
-
-2.1.13 - Enable overwriting of resident files and housekeeping of system files.
-
- - Implement writing of mft records (fs/ntfs/mft.[hc]), which includes
- keeping the mft mirror in sync with the mft when mirrored mft records
- are written. The functions are write_mft_record{,_nolock}(). The
- implementation is quite rudimentary for now with lots of things not
- implemented yet but I am not sure any of them can actually occur so
- I will wait for people to hit each one and only then implement it.
- - Commit open system inodes at umount time. This should make it
- virtually impossible for sync_mft_mirror_umount() to ever be needed.
- - Implement ->write_inode (fs/ntfs/inode.c::ntfs_write_inode()) for the
- ntfs super operations. This gives us inode writing via the VFS inode
- dirty code paths. Note: Access time updates are not implemented yet.
- - Implement fs/ntfs/mft.[hc]::{,__}mark_mft_record_dirty() and make
- fs/ntfs/aops.c::ntfs_writepage() and ntfs_commit_write() use it, thus
- finally enabling resident file overwrite! (-8 This also includes a
- placeholder for ->writepage (ntfs_mft_writepage()), which for now
- just redirties the page and returns. Also, at umount time, we for
- now throw away all mft data page cache pages after the last call to
- ntfs_commit_inode() in the hope that all inodes will have been
- written out by then and hence no dirty (meta)data will be lost. We
- also check for this case and emit an error message telling the user
- to run chkdsk.
- - Use set_page_writeback() and end_page_writeback() in the resident
- attribute code path of fs/ntfs/aops.c::ntfs_writepage() otherwise
- the radix-tree tag PAGECACHE_TAG_DIRTY remains set even though the
- page is clean.
- - Implement ntfs_mft_writepage() so it now checks if any of the mft
- records in the page are dirty and if so redirties the page and
- returns. Otherwise it just returns (after doing set_page_writeback(),
- unlock_page(), end_page_writeback() or the radix-tree tag
- PAGECACHE_TAG_DIRTY remains set even though the page is clean), thus
- alowing the VM to do with the page as it pleases. Also, at umount
- time, now only throw away dirty mft (meta)data pages if dirty inodes
- are present and ask the user to email us if they see this happening.
- - Add functions ntfs_{clear,set}_volume_flags(), to modify the volume
- information flags (fs/ntfs/super.c).
- - Mark the volume dirty when (re)mounting read-write and mark it clean
- when unmounting or remounting read-only. If any volume errors are
- found, the volume is left marked dirty to force chkdsk to run.
- - Add code to set the NT4 compatibility flag when (re)mounting
- read-write for newer NTFS versions but leave it commented out for now
- since we do not make any modifications that are NTFS 1.2 specific yet
- and since setting this flag breaks Captive-NTFS which is not nice.
- This code must be enabled once we start writing NTFS 1.2 specific
- changes otherwise Windows NTFS driver might crash / cause corruption.
-
-2.1.12 - Fix the second fix to the decompression engine and some cleanups.
-
- - Add a new address space operations struct, ntfs_mst_aops, for mst
- protected attributes. This is because the default ntfs_aops do not
- make sense with mst protected data and were they to write anything to
- such an attribute they would cause data corruption so we provide
- ntfs_mst_aops which does not have any write related operations set.
- - Cleanup dirty ntfs inode handling (fs/ntfs/inode.[hc]) which also
- includes an adapted ntfs_commit_inode() and an implementation of
- ntfs_write_inode() which for now just cleans dirty inodes without
- writing them (it does emit a warning that this is happening).
- - Undo the second decompression engine fix (see 2.1.9 release ChangeLog
- entry) as it was only fixing a theoretical bug but at the same time
- it badly broke the handling of sparse and uncompressed compression
- blocks.
-
-2.1.11 - Driver internal cleanups.
-
- - Only build logfile.o if building the driver with read-write support.
- - Really final white space cleanups.
- - Use generic_ffs() instead of ffs() in logfile.c which allows the
- log_page_size variable to be optimized by gcc into a constant.
- - Rename uchar_t to ntfschar everywhere as uchar_t is unsigned 1-byte
- char as defined by POSIX and as found on some systems.
-
-2.1.10 - Force read-only (re)mounting of volumes with unsupported volume flags.
-
- - Finish off the white space cleanups (remove trailing spaces, etc).
- - Clean up ntfs_fill_super() and ntfs_read_inode_mount() by removing
- the kludges around the first iget(). Instead of (re)setting ->s_op
- we have the $MFT inode set up by explicit new_inode() / set ->i_ino /
- insert_inode_hash() / call ntfs_read_inode_mount() directly. This
- kills the need for second super_operations and allows to return error
- from ntfs_read_inode_mount() without resorting to ugly "poisoning"
- tricks. (Al Viro)
- - Force read-only (re)mounting if any of the following bits are set in
- the volume information flags:
- VOLUME_IS_DIRTY, VOLUME_RESIZE_LOG_FILE,
- VOLUME_UPGRADE_ON_MOUNT, VOLUME_DELETE_USN_UNDERWAY,
- VOLUME_REPAIR_OBJECT_ID, VOLUME_MODIFIED_BY_CHKDSK
- To make this easier we define VOLUME_MUST_MOUNT_RO_MASK with all the
- above bits set so the test is made easy.
-
-2.1.9 - Fix two bugs in decompression engine.
-
- - Fix a bug where we would not always detect that we have reached the
- end of a compression block because we were ending at minus one byte
- which is effectively the same as being at the end. The fix is to
- check whether the uncompressed buffer has been fully filled and if so
- we assume we have reached the end of the compression block. A big
- thank you to Marcin Gibuła for the bug report, the assistance in
- tracking down the bug and testing the fix.
- - Fix a possible bug where when a compressed read is truncated to the
- end of the file, the offset inside the last page was not truncated.
-
-2.1.8 - Handle $MFT mirror and $LogFile, improve time handling, and cleanups.
-
- - Use get_bh() instead of manual atomic_inc() in fs/ntfs/compress.c.
- - Modify fs/ntfs/time.c::ntfs2utc(), get_current_ntfs_time(), and
- utc2ntfs() to work with struct timespec instead of time_t on the
- Linux UTC time side thus preserving the full precision of the NTFS
- time and only loosing up to 99 nano-seconds in the Linux UTC time.
- - Move fs/ntfs/time.c to fs/ntfs/time.h and make the time functions
- static inline.
- - Remove unused ntfs_dirty_inode().
- - Cleanup super operations declaration in fs/ntfs/super.c.
- - Wrap flush_dcache_mft_record_page() in #ifdef NTFS_RW.
- - Add NInoTestSetFoo() and NInoTestClearFoo() macro magic to
- fs/ntfs/inode.h and use it to declare NInoTest{Set,Clear}Dirty.
- - Move typedefs for ntfs_attr and test_t from fs/ntfs/inode.c to
- fs/ntfs/inode.h so they can be used elsewhere.
- - Determine the mft mirror size as the number of mirrored mft records
- and store it in ntfs_volume->mftmirr_size (fs/ntfs/super.c).
- - Load the mft mirror at mount time and compare the mft records stored
- in it to the ones in the mft. Force a read-only mount if the two do
- not match (fs/ntfs/super.c).
- - Fix type casting related warnings on 64-bit architectures. Thanks
- to Meelis Roos for reporting them.
- - Move %L to %ll as %L is floating point and %ll is integer which is
- what we want.
- - Read the journal ($LogFile) and determine if the volume has been
- shutdown cleanly and force a read-only mount if not (fs/ntfs/super.c
- and fs/ntfs/logfile.c). This is a little bit of a crude check in
- that we only look at the restart areas and not at the actual log
- records so that there will be a very small number of cases where we
- think that a volume is dirty when in fact it is clean. This should
- only affect volumes that have not been shutdown cleanly and did not
- have any pending, non-check-pointed i/o.
- - If the $LogFile indicates a clean shutdown and a read-write (re)mount
- is requested, empty $LogFile by overwriting it with 0xff bytes to
- ensure that Windows cannot cause data corruption by replaying a stale
- journal after Linux has written to the volume.
-
-2.1.7 - Enable NFS exporting of mounted NTFS volumes.
-
- - Set i_generation in the VFS inode from the seq_no of the NTFS inode.
- - Make ntfs_lookup() NFS export safe, i.e. use d_splice_alias(), etc.
- - Implement ->get_dentry() in fs/ntfs/namei.c::ntfs_get_dentry() as the
- default doesn't allow inode number 0 which is a valid inode on NTFS
- and even if it did allow that it uses iget() instead of ntfs_iget()
- which makes it useless for us.
- - Implement ->get_parent() in fs/ntfs/namei.c::ntfs_get_parent() as the
- default just returns -EACCES which is not very useful.
- - Define export operations (->s_export_op) for NTFS (ntfs_export_ops)
- and set them up in the super block at mount time (super.c) this
- allows mounted NTFS volumes to be exported via NFS.
- - Add missing return -EOPNOTSUPP; in
- fs/ntfs/aops.c::ntfs_commit_nonresident_write().
- - Enforce no atime and no dir atime updates at mount/remount time as
- they are not implemented yet anyway.
- - Move a few assignments in fs/ntfs/attrib.c::load_attribute_list() to
- after a NULL check. Thanks to Dave Jones for pointing this out.
-
-2.1.6 - Fix minor bug in handling of compressed directories.
-
- - Fix bug in handling of compressed directories. A compressed
- directory is not really compressed so when we set the ->i_blocks
- field of a compressed directory inode we were setting it from the
- non-existing field ni->itype.compressed.size which gave random
- results... For directories we now always use ni->allocated_size.
-
-2.1.5 - Fix minor bug in attribute list attribute handling.
-
- - Fix bug in attribute list handling. Actually it is not as much a bug
- as too much protection in that we were not allowing attribute lists
- which waste space on disk while Windows XP clearly allows it and in
- fact creates such attribute lists so our driver was failing.
- - Update NTFS documentation ready for 2.6 kernel release.
-
-2.1.4 - Reduce compiler requirements.
-
- - Remove all uses of unnamed structs and unions in the driver to make
- old and newer gcc versions happy. Makes it a bit uglier IMO but at
- least people will stop hassling me about it.
-
-2.1.3 - Important bug fixes in corner cases.
-
- - super.c::parse_ntfs_boot_sector(): Correct the check for 64-bit
- clusters. (Philipp Thomas)
- - attrib.c::load_attribute_list(): Fix bug when initialized_size is a
- multiple of the block_size but not the cluster size. (Szabolcs
- Szakacsits)
-
-2.1.2 - Important bug fixes aleviating the hangs in statfs.
-
- - Fix buggy free cluster and free inode determination logic.
-
-2.1.1 - Minor updates.
-
- - Add handling for initialized_size != data_size in compressed files.
- - Reduce function local stack usage from 0x3d4 bytes to just noise in
- fs/ntfs/upcase.c. (Randy Dunlap)
- - Remove compiler warnings for newer gcc.
- - Pages are no longer kmapped by mm/filemap.c::generic_file_write()
- around calls to ->{prepare,commit}_write. Adapt NTFS appropriately
- in fs/ntfs/aops.c::ntfs_prepare_nonresident_write() by using
- kmap_atomic(KM_USER0).
-
-2.1.0 - First steps towards write support: implement file overwrite.
-
- - Add configuration option for developmental write support with an
- appropriately scary configuration help text.
- - Initial implementation of fs/ntfs/aops.c::ntfs_writepage() and its
- helper fs/ntfs/aops.c::ntfs_write_block(). This enables mmap(2) based
- overwriting of existing files on ntfs. Note: Resident files are
- only written into memory, and not written out to disk at present, so
- avoid writing to files smaller than about 1kiB.
- - Initial implementation of fs/ntfs/aops.c::ntfs_prepare_write(), its
- helper fs/ntfs/aops.c::ntfs_prepare_nonresident_write() and their
- counterparts, fs/ntfs/aops.c::ntfs_commit_write(), and
- fs/ntfs/aops.c::ntfs_commit_nonresident_write(), respectively. Also,
- add generic_file_write() to the ntfs file operations (fs/ntfs/file.c).
- This enables write(2) based overwriting of existing files on ntfs.
- Note: As with mmap(2) based overwriting, resident files are only
- written into memory, and not written out to disk at present, so avoid
- writing to files smaller than about 1kiB.
- - Implement ->truncate (fs/ntfs/inode.c::ntfs_truncate()) and
- ->setattr() (fs/ntfs/inode.c::ntfs_setattr()) inode operations for
- files with the purpose of intercepting and aborting all i_size
- changes which we do not support yet. ntfs_truncate() actually only
- emits a warning message but AFAICS our interception of i_size changes
- elsewhere means ntfs_truncate() never gets called for i_size changes.
- It is only called from generic_file_write() when we fail in
- ntfs_prepare_{,nonresident_}write() in order to discard any
- instantiated buffers beyond i_size. Thus i_size is not actually
- changed so our warning message is enough. Unfortunately it is not
- possible to easily determine if i_size is being changed or not hence
- we just emit an appropriately worded error message.
-
-2.0.25 - Small bug fixes and cleanups.
-
- - Unlock the page in an out of memory error code path in
- fs/ntfs/aops.c::ntfs_read_block().
- - If fs/ntfs/aops.c::ntfs_read_page() is called on an uptodate page,
- just unlock the page and return. (This can happen due to ->writepage
- clearing PageUptodate() during write out of MstProtected()
- attributes.
- - Remove leaked write code again.
-
-2.0.24 - Cleanups.
-
- - Treat BUG_ON() as ASSERT() not VERIFY(), i.e. do not use side effects
- inside BUG_ON(). (Adam J. Richter)
- - Split logical OR expressions inside BUG_ON() into individual BUG_ON()
- calls for improved debugging. (Adam J. Richter)
- - Add errors flag to the ntfs volume state, accessed via
- NVol{,Set,Clear}Errors(vol).
- - Do not allow read-write remounts of read-only volumes with errors.
- - Clarify comment for ntfs file operation sendfile which was added by
- Christoph Hellwig a while ago (just using generic_file_sendfile())
- to say that ntfs ->sendfile is only used for the case where the
- source data is on the ntfs partition and the destination is
- somewhere else, i.e. nothing we need to concern ourselves with.
- - Add generic_file_write() as our ntfs file write operation.
-
-2.0.23 - Major bug fixes (races, deadlocks, non-i386 architectures).
-
- - Massive internal locking changes to mft record locking. Fixes lock
- recursion and replaces the mrec_lock read/write semaphore with a
- mutex. Also removes the now superfluous mft_count. This fixes several
- race conditions and deadlocks, especially in the future write code.
- - Fix ntfs over loopback for compressed files by adding an
- optimization barrier. (gcc was screwing up otherwise ?)
- - Miscellaneous cleanups all over the code and a fix or two in error
- handling code paths.
- Thanks go to Christoph Hellwig for pointing out the following two:
- - Remove now unused function fs/ntfs/malloc.h::vmalloc_nofs().
- - Fix ntfs_free() for ia64 and parisc by checking for VMALLOC_END, too.
-
-2.0.22 - Cleanups, mainly to ntfs_readdir(), and use C99 initializers.
-
- - Change fs/ntfs/dir.c::ntfs_reddir() to only read/write ->f_pos once
- at entry/exit respectively.
- - Use C99 initializers for structures.
- - Remove unused variable blocks from fs/ntfs/aops.c::ntfs_read_block().
-
-2.0.21 - Check for, and refuse to work with too large files/directories/volumes.
-
- - Limit volume size at mount time to 2TiB on architectures where
- unsigned long is 32-bits (fs/ntfs/super.c::parse_ntfs_boot_sector()).
- This is the most we can do without overflowing the 32-bit limit of
- the block device size imposed on us by sb_bread() and sb_getblk()
- for the time being.
- - Limit file/directory size at open() time to 16TiB on architectures
- where unsigned long is 32-bits (fs/ntfs/file.c::ntfs_file_open() and
- fs/ntfs/dir.c::ntfs_dir_open()). This is the most we can do without
- overflowing the page cache page index.
-
-2.0.20 - Support non-resident directory index bitmaps, fix page leak in readdir.
-
- - Move the directory index bitmap to use an attribute inode instead of
- having special fields for it inside the ntfs inode structure. This
- means that the index bitmaps now use the page cache for i/o, too,
- and also as a side effect we get support for non-resident index
- bitmaps for free.
- - Simplify/cleanup error handling in fs/ntfs/dir.c::ntfs_readdir() and
- fix a page leak that manifested itself in some cases.
- - Add fs/ntfs/inode.c::ntfs_put_inode(), which we need to release the
- index bitmap inode on the final iput().
-
-2.0.19 - Fix race condition, improvements, and optimizations in i/o interface.
-
- - Apply block optimization added to fs/ntfs/aops.c::ntfs_read_block()
- to fs/ntfs/compress.c::ntfs_file_read_compressed_block() as well.
- - Drop the "file" from ntfs_file_read_compressed_block().
- - Rename fs/ntfs/aops.c::ntfs_enb_buffer_read_async() to
- ntfs_end_buffer_async_read() (more like the fs/buffer.c counterpart).
- - Update ntfs_end_buffer_async_read() with the improved logic from
- its updated counterpart fs/buffer.c::end_buffer_async_read(). Apply
- further logic improvements to better determine when we set PageError.
- - Update submission of buffers in fs/ntfs/aops.c::ntfs_read_block() to
- check for the buffers being uptodate first in line with the updated
- fs/buffer.c::block_read_full_page(). This plugs a small race
- condition.
-
-2.0.18 - Fix race condition in reading of compressed files.
-
- - There was a narrow window between checking a buffer head for being
- uptodate and locking it in ntfs_file_read_compressed_block(). We now
- lock the buffer and then check whether it is uptodate or not.
-
-2.0.17 - Cleanups and optimizations - shrinking the ToDo list.
-
- - Modify fs/ntfs/inode.c::ntfs_read_locked_inode() to return an error
- code and update callers, i.e. ntfs_iget(), to pass that error code
- up instead of just using -EIO.
- - Modifications to super.c to ensure that both mount and remount
- cannot set any write related options when the driver is compiled
- read-only.
- - Optimize block resolution in fs/ntfs/aops.c::ntfs_read_block() to
- cache the current runlist element. This should improve performance
- when reading very large and/or very fragmented data.
-
-2.0.16 - Convert access to $MFT/$BITMAP to attribute inode API.
-
- - Fix a stupid bug introduced in 2.0.15 where we were unmapping the
- wrong inode in fs/ntfs/inode.c::ntfs_attr_iget().
- - Fix debugging check in fs/ntfs/aops.c::ntfs_read_block().
- - Convert $MFT/$BITMAP access to attribute inode API and remove all
- remnants of the ugly mftbmp address space and operations hack. This
- means we finally have only one readpage function as well as only one
- async io completion handler. Yey! The mft bitmap is now just an
- attribute inode and is accessed from vol->mftbmp_ino just as if it
- were a normal file. Fake inodes rule. (-:
-
-2.0.15 - Fake inodes based attribute i/o via the pagecache, fixes and cleanups.
-
- - Fix silly bug in fs/ntfs/super.c::parse_options() which was causing
- remounts to fail when the partition had an entry in /etc/fstab and
- the entry specified the nls= option.
- - Apply same macro magic used in fs/ntfs/inode.h to fs/ntfs/volume.h to
- expand all the helper functions NVolFoo(), NVolSetFoo(), and
- NVolClearFoo().
- - Move copyright statement from driver initialisation message to
- module description (fs/super.c). This makes the initialisation
- message fit on one line and fits in better with rest of kernel.
- - Update fs/ntfs/attrib.c::map_run_list() to work on both real and
- attribute inodes, and both for files and directories.
- - Implement fake attribute inodes allowing all attribute i/o to go via
- the page cache and to use all the normal vfs/mm functionality:
- - Add ntfs_attr_iget() and its helper ntfs_read_locked_attr_inode()
- to fs/ntfs/inode.c.
- - Add needed cleanup code to ntfs_clear_big_inode().
- - Merge address space operations for files and directories (aops.c),
- now just have ntfs_aops:
- - Rename:
- end_buffer_read_attr_async() -> ntfs_end_buffer_read_async(),
- ntfs_attr_read_block() -> ntfs_read_block(),
- ntfs_file_read_page() -> ntfs_readpage().
- - Rewrite fs/ntfs/aops.c::ntfs_readpage() to work on both real and
- attribute inodes, and both for files and directories.
- - Remove obsolete fs/ntfs/aops.c::ntfs_mst_readpage().
-
-2.0.14 - Run list merging code cleanup, minor locking changes, typo fixes.
-
- - Change fs/ntfs/super.c::ntfs_statfs() to not rely on BKL by moving
- the locking out of super.c::get_nr_free_mft_records() and taking and
- dropping the mftbmp_lock rw_semaphore in ntfs_statfs() itself.
- - Bring attribute runlist merging code (fs/ntfs/attrib.c) in sync with
- current userspace ntfs library code. This means that if a merge
- fails the original runlists are always left unmodified instead of
- being silently corrupted.
- - Misc typo fixes.
-
-2.0.13 - Use iget5_locked() in preparation for fake inodes and small cleanups.
-
- - Remove nr_mft_bits and the now superfluous union with nr_mft_records
- from ntfs_volume structure.
- - Remove nr_lcn_bits and the now superfluous union with nr_clusters
- from ntfs_volume structure.
- - Use iget5_locked() and friends instead of conventional iget(). Wrap
- the call in fs/ntfs/inode.c::ntfs_iget() and update callers of iget()
- to use ntfs_iget(). Leave only one iget() call at mount time so we
- don't need an ntfs_iget_mount().
- - Change fs/ntfs/inode.c::ntfs_new_extent_inode() to take mft_no as an
- additional argument.
-
-2.0.12 - Initial cleanup of address space operations following 2.0.11 changes.
-
- - Merge fs/ntfs/aops.c::end_buffer_read_mst_async() and
- fs/ntfs/aops.c::end_buffer_read_file_async() into one function
- fs/ntfs/aops.c::end_buffer_read_attr_async() using NInoMstProtected()
- to determine whether to apply mst fixups or not.
- - Above change allows merging fs/ntfs/aops.c::ntfs_file_read_block()
- and fs/ntfs/aops.c::ntfs_mst_readpage() into one function
- fs/ntfs/aops.c::ntfs_attr_read_block(). Also, create a tiny wrapper
- fs/ntfs/aops.c::ntfs_mst_readpage() to transform the parameters from
- the VFS readpage function prototype to the ntfs_attr_read_block()
- function prototype.
-
-2.0.11 - Initial preparations for fake inode based attribute i/o.
-
- - Move definition of ntfs_inode_state_bits to fs/ntfs/inode.h and
- do some macro magic (adapted from include/linux/buffer_head.h) to
- expand all the helper functions NInoFoo(), NInoSetFoo(), and
- NInoClearFoo().
- - Add new flag to ntfs_inode_state_bits: NI_Sparse.
- - Add new fields to ntfs_inode structure to allow use of fake inodes
- for attribute i/o: type, name, name_len. Also add new state bits:
- NI_Attr, which, if set, indicates the inode is a fake inode, and
- NI_MstProtected, which, if set, indicates the attribute uses multi
- sector transfer protection, i.e. fixups need to be applied after
- reads and before/after writes.
- - Rename fs/ntfs/inode.c::ntfs_{new,clear,destroy}_inode() to
- ntfs_{new,clear,destroy}_extent_inode() and update callers.
- - Use ntfs_clear_extent_inode() in fs/ntfs/inode.c::__ntfs_clear_inode()
- instead of ntfs_destroy_extent_inode().
- - Cleanup memory deallocations in {__,}ntfs_clear_{,big_}inode().
- - Make all operations on ntfs inode state bits use the NIno* functions.
- - Set up the new ntfs inode fields and state bits in
- fs/ntfs/inode.c::ntfs_read_inode() and add appropriate cleanup of
- allocated memory to __ntfs_clear_inode().
- - Cleanup ntfs_inode structure a bit for better ordering of elements
- w.r.t. their size to allow better packing of the structure in memory.
-
-2.0.10 - There can only be 2^32 - 1 inodes on an NTFS volume.
-
- - Add check at mount time to verify that the number of inodes on the
- volume does not exceed 2^32 - 1, which is the maximum allowed for
- NTFS according to Microsoft.
- - Change mft_no member of ntfs_inode structure to be unsigned long.
- Update all users. This makes ntfs_inode->mft_no just a copy of struct
- inode->i_ino. But we can't just always use struct inode->i_ino and
- remove mft_no because extent inodes do not have an attached struct
- inode.
-
-2.0.9 - Decompression engine now uses a single buffer and other cleanups.
-
- - Change decompression engine to use a single buffer protected by a
- spin lock instead of per-CPU buffers. (Rusty Russell)
- - Do not update cb_pos when handling a partial final page during
- decompression of a sparse compression block, as the value is later
- reset without being read/used. (Rusty Russell)
- - Switch to using the new KM_BIO_SRC_IRQ for atomic kmap()s. (Andrew
- Morton)
- - Change buffer size in ntfs_readdir()/ntfs_filldir() to use
- NLS_MAX_CHARSET_SIZE which makes the buffers almost 1kiB each but
- it also makes everything safer so it is a good thing.
- - Miscellaneous minor cleanups to comments.
-
-2.0.8 - Major updates for handling of case sensitivity and dcache aliasing.
-
- Big thanks go to Al Viro and other inhabitants of #kernel for investing
- their time to discuss the case sensitivity and dcache aliasing issues.
-
- - Remove unused source file fs/ntfs/attraops.c.
- - Remove show_inodes mount option(s), thus dropping support for
- displaying of short file names.
- - Remove deprecated mount option posix.
- - Restore show_sys_files mount option.
- - Add new mount option case_sensitive, to determine if the driver
- treats file names as case sensitive or not. If case sensitive, create
- file names in the POSIX namespace. Otherwise create file names in the
- LONG/WIN32 namespace. Note, files remain accessible via their short
- file name, if it exists.
- - Remove really dumb logic bug in boot sector recovery code.
- - Fix dcache aliasing issues wrt short/long file names via changes
- to fs/ntfs/dir.c::ntfs_lookup_inode_by_name() and
- fs/ntfs/namei.c::ntfs_lookup():
- - Add additional argument to ntfs_lookup_inode_by_name() in which we
- return information about the matching file name if the case is not
- matching or the match is a short file name. See comments above the
- function definition for details.
- - Change ntfs_lookup() to only create dcache entries for the correctly
- cased file name and only for the WIN32 namespace counterpart of DOS
- namespace file names. This ensures we have only one dentry per
- directory and also removes all dcache aliasing issues between short
- and long file names once we add write support. See comments above
- function for details.
- - Fix potential 1 byte overflow in fs/ntfs/unistr.c::ntfs_ucstonls().
-
-2.0.7 - Minor cleanups and updates for changes in core kernel code.
-
- - Remove much of the NULL struct element initializers.
- - Various updates to make compatible with recent kernels.
- - Remove defines of MAX_BUF_PER_PAGE and include linux/buffer_head.h
- in fs/ntfs/ntfs.h instead.
- - Remove no longer needed KERNEL_VERSION checks. We are now in the
- kernel proper so they are no longer needed.
-
-2.0.6 - Major bugfix to make compatible with other kernel changes.
-
- - Initialize the mftbmp address space properly now that there are more
- fields in the struct address_space. This was leading to hangs and
- oopses on umount since 2.5.12 because of changes to other parts of
- the kernel. We probably want a kernel generic init_address_space()
- function...
- - Drop BKL from ntfs_readdir() after consultation with Al Viro. The
- only caller of ->readdir() is vfs_readdir() which holds i_mutex
- during the call, and i_mutex is sufficient protection against changes
- in the directory inode (including ->i_size).
- - Use generic_file_llseek() for directories (as opposed to
- default_llseek()) as this downs i_mutex instead of the BKL which is
- what we now need for exclusion against ->f_pos changes considering we
- no longer take the BKL in ntfs_readdir().
-
-2.0.5 - Major bugfix. Buffer overflow in extent inode handling.
-
- - No need to set old blocksize in super.c::ntfs_fill_super() as the
- VFS does so via invocation of deactivate_super() calling
- fs->fill_super() calling block_kill_super() which does it.
- - BKL moved from VFS into dir.c::ntfs_readdir(). (Linus Torvalds)
- -> Do we really need it? I don't think so as we have exclusion on
- the directory ntfs_inode rw_semaphore mrec_lock. We mmight have to
- move the ->f_pos accesses under the mrec_lock though. Check this...
- - Fix really, really, really stupid buffer overflow in extent inode
- handling in mft.c::map_extent_mft_record().
-
-2.0.4 - Cleanups and updates for kernel 2.5.11.
-
- - Add documentation on how to use the MD driver to be able to use NTFS
- stripe and volume sets in Linux and generally cleanup documentation
- a bit.
- Remove all uses of kdev_t in favour of struct block_device *:
- - Change compress.c::ntfs_file_read_compressed_block() to use
- sb_getblk() instead of getblk().
- - Change super.c::ntfs_fill_super() to use bdev_hardsect_size() instead
- of get_hardsect_size().
- - No need to get old blocksize in super.c::ntfs_fill_super() as
- fs/super.c::get_sb_bdev() already does this.
- - Set bh->b_bdev instead of bh->b_dev throughout aops.c.
-
-2.0.3 - Small bug fixes, cleanups, and performance improvements.
-
- - Remove some dead code from mft.c.
- - Optimize readpage and read_block functions throughout aops.c so that
- only initialized blocks are read. Non-initialized ones have their
- buffer head mapped, zeroed, and set up to date, without scheduling
- any i/o. Thanks to Al Viro for advice on how to avoid the device i/o.
- Thanks go to Andrew Morton for spotting the below:
- - Fix buglet in allocate_compression_buffers() error code path.
- - Call flush_dcache_page() after modifying page cache page contents in
- ntfs_file_readpage().
- - Check for existence of page buffers throughout aops.c before calling
- create_empty_buffers(). This happens when an I/O error occurs and the
- read is retried. (It also happens once writing is implemented so that
- needed doing anyway but I had left it for later...)
- - Don't BUG_ON() uptodate and/or mapped buffers throughout aops.c in
- readpage and read_block functions. Reasoning same as above (i.e. I/O
- error retries and future write code paths.)
-
-2.0.2 - Minor updates and cleanups.
-
- - Cleanup: rename mst.c::__post_read_mst_fixup to post_write_mst_fixup
- and cleanup the code a bit, removing the unused size parameter.
- - Change default fmask to 0177 and update documentation.
- - Change attrib.c::get_attr_search_ctx() to return the search context
- directly instead of taking the address of a pointer. A return value
- of NULL means the allocation failed. Updated all callers
- appropriately.
- - Update to 2.5.9 kernel (preserving backwards compatibility) by
- replacing all occurences of page->buffers with page_buffers(page).
- - Fix minor bugs in runlist merging, also minor cleanup.
- - Updates to bootsector layout and mft mirror contents descriptions.
- - Small bug fix in error detection in unistr.c and some cleanups.
- - Grow name buffer allocations in unistr.c in aligned mutlipled of 64
- bytes.
-
-2.0.1 - Minor updates.
-
- - Make default umask correspond to documentation.
- - Improve documentation.
- - Set default mode to include execute bit. The {u,f,d}mask can be used
- to take it away if desired. This allows binaries to be executed from
- a mounted ntfs partition.
-
-2.0.0 - New version number. Remove TNG from the name. Now in the kernel.
-
- - Add kill_super, just keeping up with the vfs changes in the kernel.
- - Repeat some changes from tng-0.0.8 that somehow got lost on the way
- from the CVS import into BitKeeper.
- - Begin to implement proper handling of allocated_size vs
- initialized_size vs data_size (i.e. i_size). Done are
- mft.c::ntfs_mft_readpage(), aops.c::end_buffer_read_index_async(),
- and attrib.c::load_attribute_list().
- - Lock the runlist in attrib.c::load_attribute_list() while using it.
- - Fix memory leak in ntfs_file_read_compressed_block() and generally
- clean up compress.c a little, removing some uncommented/unused debug
- code.
- - Tidy up dir.c a little bit.
- - Don't bother getting the runlist in inode.c::ntfs_read_inode().
- - Merge mft.c::ntfs_mft_readpage() and aops.c::ntfs_index_readpage()
- creating aops.c::ntfs_mst_readpage(), improving the handling of
- holes and overflow in the process and implementing the correct
- equivalent of ntfs_file_get_block() in ntfs_mst_readpage() itself.
- I am aiming for correctness at the moment. Modularisation can come
- later.
- - Rename aops.c::end_buffer_read_index_async() to
- end_buffer_read_mst_async() and optimize the overflow checking and
- handling.
- - Use the host of the mftbmp address space mapping to hold the ntfs
- volume. This is needed so the async i/o completion handler can
- retrieve a pointer to the volume. Hopefully this will not cause
- problems elsewhere in the kernel... Otherwise will need to use a
- fake inode.
- - Complete implementation of proper handling of allocated_size vs
- initialized_size vs data_size (i.e. i_size) in whole driver.
- Basically aops.c is now completely rewritten.
- - Change NTFS driver name to just NTFS and set version number to 2.0.0
- to make a clear distinction from the old driver which is still on
- version 1.1.22.
-
-tng-0.0.8 - 08/03/2002 - Now using BitKeeper, http://linux-ntfs.bkbits.net/
-
- - Replace bdevname(sb->s_dev) with sb->s_id.
- - Remove now superfluous new-line characters in all callers of
- ntfs_debug().
- - Apply kludge in ntfs_read_inode(), setting i_nlink to 1 for
- directories. Without this the "find" utility gets very upset which is
- fair enough as Linux/Unix do not support directory hard links.
- - Further runlist merging work. (Richard Russon)
- - Backwards compatibility for gcc-2.95. (Richard Russon)
- - Update to kernel 2.5.5-pre1 and rediff the now tiny patch.
- - Convert to new filesystem declaration using ->ntfs_get_sb() and
- replacing ntfs_read_super() with ntfs_fill_super().
- - Set s_maxbytes to MAX_LFS_FILESIZE to avoid page cache page index
- overflow on 32-bit architectures.
- - Cleanup upcase loading code to use ntfs_(un)map_page().
- - Disable/reenable preemtion in critical sections of compession engine.
- - Replace device size determination in ntfs_fill_super() with
- sb->s_bdev->bd_inode->i_size (in bytes) and remove now superfluous
- function super.c::get_nr_blocks().
- - Implement a mount time option (show_inodes) allowing choice of which
- types of inode names readdir() returns and modify ntfs_filldir()
- accordingly. There are several parameters to show_inodes:
- system: system files
- win32: long file names (including POSIX file names) [DEFAULT]
- long: same as win32
- dos: short file names only (excluding POSIX file names)
- short: same as dos
- posix: same as both win32 and dos
- all: all file names
- Note that the options are additive, i.e. specifying:
- -o show_inodes=system,show_inodes=win32,show_inodes=dos
- is the same as specifying:
- -o show_inodes=all
- Note that the "posix" and "all" options will show all directory
- names, BUT the link count on each directory inode entry is set to 1,
- due to Linux not supporting directory hard links. This may well
- confuse some userspace applications, since the directory names will
- have the same inode numbers. Thus it is NOT advisable to use the
- "posix" or "all" options. We provide them only for completeness sake.
- - Add copies of allocated_size, initialized_size, and compressed_size to
- the ntfs inode structure and set them up in
- inode.c::ntfs_read_inode(). These reflect the unnamed data attribute
- for files and the index allocation attribute for directories.
- - Add copies of allocated_size and initialized_size to ntfs inode for
- $BITMAP attribute of large directories and set them up in
- inode.c::ntfs_read_inode().
- - Add copies of allocated_size and initialized_size to ntfs volume for
- $BITMAP attribute of $MFT and set them up in
- super.c::load_system_files().
- - Parse deprecated ntfs driver options (iocharset, show_sys_files,
- posix, and utf8) and tell user what the new options to use are. Note
- we still do support them but they will be removed with kernel 2.7.x.
- - Change all occurences of integer long long printf formatting to hex
- as printk() will not support long long integer format if/when the
- div64 patch goes into the kernel.
- - Make slab caches have stable names and change the names to what they
- were intended to be. These changes are required/made possible by the
- new slab cache name handling which removes the length limitation by
- requiring the caller of kmem_cache_create() to supply a stable name
- which is then referenced but not copied.
- - Rename run_list structure to run_list_element and create a new
- run_list structure containing a pointer to a run_list_element
- structure and a read/write semaphore. Adapt all users of runlists
- to new scheme and take and release the lock as needed. This fixes a
- nasty race as the run_list changes even when inodes are locked for
- reading and even when the inode isn't locked at all, so we really
- needed the serialization. We use a semaphore rather than a spinlock
- as memory allocations can sleep and doing everything GFP_ATOMIC
- would be silly.
- - Cleanup read_inode() removing all code checking for lowest_vcn != 0.
- This can never happen due to the nature of lookup_attr() and how we
- support attribute lists. If it did happen it would imply the inode
- being corrupt.
- - Check for lowest_vcn != 0 in ntfs_read_inode() and mark the inode as
- bad if found.
- - Update to 2.5.6-pre2 changes in struct address_space.
- - Use parent_ino() when accessing d_parent inode number in dir.c.
- - Import Sourceforge CVS repository into BitKeeper repository:
- http://linux-ntfs.bkbits.net/ntfs-tng-2.5
- - Update fs/Makefile, fs/Config.help, fs/Config.in, and
- Documentation/filesystems/ntfs.txt for NTFS TNG.
- - Create kernel configuration option controlling whether debugging
- is enabled or not.
- - Add the required export of end_buffer_io_sync() from the patches
- directory to the kernel code.
- - Update inode.c::ntfs_show_options() with show_inodes mount option.
- - Update errors mount option.
-
-tng-0.0.7 - 13/02/2002 - The driver is now feature complete for read-only!
-
- - Cleanup mft.c and it's debug/error output in particular. Fix a minor
- bug in mapping of extent inodes. Update all the comments to fit all
- the recent code changes.
- - Modify vcn_to_lcn() to cope with entirely unmapped runlists.
- - Cleanups in compress.c, mostly comments and folding help.
- - Implement attrib.c::map_run_list() as a generic helper.
- - Make compress.c::ntfs_file_read_compressed_block() use map_run_list()
- thus making code shorter and enabling attribute list support.
- - Cleanup incorrect use of [su]64 with %L printf format specifier in
- all source files. Type casts to [unsigned] long long added to correct
- the mismatches (important for architectures which have long long not
- being 64 bits).
- - Merge async io completion handlers for directory indexes and $MFT
- data into one by setting the index_block_size{_bits} of the ntfs
- inode for $MFT to the mft_record_size{_bits} of the ntfs_volume.
- - Cleanup aops.c, update comments.
- - Make ntfs_file_get_block() use map_run_list() so all files now
- support attribute lists.
- - Make ntfs_dir_readpage() almost verbatim copy of
- block_read_full_page() by using ntfs_file_get_block() with only real
- difference being the use of our own async io completion handler
- rather than the default one, thus reducing the amount of code and
- automatically enabling attribute list support for directory indices.
- - Fix bug in load_attribute_list() - forgot to call brelse in error
- code path.
- - Change parameters to find_attr() and lookup_attr(). We no longer
- pass in the upcase table and its length. These can be gotten from
- ctx->ntfs_ino->vol->upcase{_len}. Update all callers.
- - Cleanups in attrib.c.
- - Implement merging of runlists, attrib.c::merge_run_lists() and its
- helpers. (Richard Russon)
- - Attribute lists part 2, attribute extents and multi part runlists:
- enable proper support for LCN_RL_NOT_MAPPED and automatic mapping of
- further runlist parts via attrib.c::map_run_list().
- - Tiny endianness bug fix in decompress_mapping_pairs().
-
-tng-0.0.6 - Encrypted directories, bug fixes, cleanups, debugging enhancements.
-
- - Enable encrypted directories. (Their index root is marked encrypted
- to indicate that new files in that directory should be created
- encrypted.)
- - Fix bug in NInoBmpNonResident() macro. (Cut and paste error.)
- - Enable $Extend system directory. Most (if not all) extended system
- files do not have unnamed data attributes so ntfs_read_inode() had to
- special case them but that is ok, as the special casing recovery
- happens inside an error code path so there is zero slow down in the
- normal fast path. The special casing is done by introducing a new
- function inode.c::ntfs_is_extended_system_file() which checks if any
- of the hard links in the inode point to $Extend as being their parent
- directory and if they do we assume this is an extended system file.
- - Create a sysctl/proc interface to allow {dis,en}abling of debug output
- when compiled with -DDEBUG. Default is debug messages to be disabled.
- To enable them, one writes a non-zero value to /proc/sys/fs/ntfs-debug
- (if /proc is enabled) or uses sysctl(2) to effect the same (if sysctl
- interface is enabled). Inspired by old ntfs driver.
- - Add debug_msgs insmod/kernel boot parameter to set whether debug
- messages are {dis,en}abled. This is useful to enable debug messages
- during ntfs initialization and is the only way to activate debugging
- when the sysctl interface is not enabled.
- - Cleanup debug output in various places.
- - Remove all dollar signs ($) from the source (except comments) to
- enable compilation on architectures whose gcc compiler does not
- support dollar signs in the names of variables/constants. Attribute
- types now start with AT_ instead of $ and $I30 is now just I30.
- - Cleanup ntfs_lookup() and add consistency check of sequence numbers.
- - Load complete runlist for $MFT/$BITMAP during mount and cleanup
- access functions. This means we now cope with $MFT/$BITMAP being
- spread accross several mft records.
- - Disable modification of mft_zone_multiplier on remount. We can always
- reenable this later on if we really want to, but we will need to make
- sure we readjust the mft_zone size / layout accordingly.
-
-tng-0.0.5 - Modernize for 2.5.x and further in line-ing with Al Viro's comments.
-
- - Use sb_set_blocksize() instead of set_blocksize() and verify the
- return value.
- - Use sb_bread() instead of bread() throughout.
- - Add index_vcn_size{_bits} to ntfs_inode structure to store the size
- of a directory index block vcn. Apply resulting simplifications in
- dir.c everywhere.
- - Fix a small bug somewhere (but forgot what it was).
- - Change ntfs_{debug,error,warning} to enable gcc to do type checking
- on the printf-format parameter list and fix bugs reported by gcc
- as a result. (Richard Russon)
- - Move inode allocation strategy to Al's new stuff but maintain the
- divorce of ntfs_inode from struct inode. To achieve this we have two
- separate slab caches, one for big ntfs inodes containing a struct
- inode and pure ntfs inodes and at the same time fix some faulty
- error code paths in ntfs_read_inode().
- - Show mount options in proc (inode.c::ntfs_show_options()).
-
-tng-0.0.4 - Big changes, getting in line with Al Viro's comments.
-
- - Modified (un)map_mft_record functions to be common for read and write
- case. To specify which is which, added extra parameter at front of
- parameter list. Pass either READ or WRITE to this, each has the
- obvious meaning.
- - General cleanups to allow for easier folding in vi.
- - attrib.c::decompress_mapping_pairs() now accepts the old runlist
- argument, and invokes attrib.c::merge_run_lists() to merge the old
- and the new runlists.
- - Removed attrib.c::find_first_attr().
- - Implemented loading of attribute list and complete runlist for $MFT.
- This means we now cope with $MFT being spread across several mft
- records.
- - Adapt to 2.5.2-pre9 and the changed create_empty_buffers() syntax.
- - Adapt major/minor/kdev_t/[bk]devname stuff to new 2.5.x kernels.
- - Make ntfs_volume be allocated via kmalloc() instead of using a slab
- cache. There are too little ntfs_volume structures at any one time
- to justify a private slab cache.
- - Fix bogus kmap() use in async io completion. Now use kmap_atomic().
- Use KM_BIO_IRQ on advice from IRC/kernel...
- - Use ntfs_map_page() in map_mft_record() and create ->readpage method
- for reading $MFT (ntfs_mft_readpage). In the process create dedicated
- address space operations (ntfs_mft_aops) for $MFT inode mapping. Also
- removed the now superfluous exports from the kernel core patch.
- - Fix a bug where kfree() was used instead of ntfs_free().
- - Change map_mft_record() to take ntfs_inode as argument instead of
- vfs inode. Dito for unmap_mft_record(). Adapt all callers.
- - Add pointer to ntfs_volume to ntfs_inode.
- - Add mft record number and sequence number to ntfs_inode. Stop using
- i_ino and i_generation for in-driver purposes.
- - Implement attrib.c::merge_run_lists(). (Richard Russon)
- - Remove use of proper inodes by extent inodes. Move i_ino and
- i_generation to ntfs_inode to do this. Apply simplifications that
- result and remove iget_no_wait(), etc.
- - Pass ntfs_inode everywhere in the driver (used to be struct inode).
- - Add reference counting in ntfs_inode for the ntfs inode itself and
- for the mapped mft record.
- - Extend mft record mapping so we can (un)map extent mft records (new
- functions (un)map_extent_mft_record), and so mappings are reference
- counted and don't have to happen twice if already mapped - just ref
- count increases.
- - Add -o iocharset as alias to -o nls for backwards compatibility.
- - The latest core patch is now tiny. In fact just a single additional
- export is necessary over the base kernel.
-
-tng-0.0.3 - Cleanups, enhancements, bug fixes.
-
- - Work on attrib.c::decompress_mapping_pairs() to detect base extents
- and setup the runlist appropriately using knowledge provided by the
- sizes in the base attribute record.
- - Balance the get_/put_attr_search_ctx() calls so we don't leak memory
- any more.
- - Introduce ntfs_malloc_nofs() and ntfs_free() to allocate/free a single
- page or use vmalloc depending on the amount of memory requested.
- - Cleanup error output. The __FUNCTION__ "(): " is now added
- automatically. Introduced a new header file debug.h to support this
- and also moved ntfs_debug() function into it.
- - Make reading of compressed files more intelligent and especially get
- rid of the vmalloc_nofs() from readpage(). This now uses per CPU
- buffers (allocated at first mount with cluster size <= 4kiB and
- deallocated on last umount with cluster size <= 4kiB), and
- asynchronous io for the compressed data using a list of buffer heads.
- Er, we use synchronous io as async io only works on whole pages
- covered by buffers and not on individual buffer heads...
- - Bug fix for reading compressed files with sparse compression blocks.
-
-tng-0.0.2 - Now handles larger/fragmented/compressed volumes/files/dirs.
-
- - Fixed handling of directories when cluster size exceeds index block
- size.
- - Hide DOS only name space directory entries from readdir() but allow
- them in lookup(). This should fix the problem that Linux doesn't
- support directory hard links, while still allowing access to entries
- via their short file name. This also has the benefit of mimicking
- what Windows users are used to, so it is the ideal solution.
- - Implemented sync_page everywhere so no more hangs in D state when
- waiting for a page.
- - Stop using bforget() in favour of brelse().
- - Stop locking buffers unnecessarily.
- - Implemented compressed files (inode->mapping contains uncompressed
- data, raw compressed data is currently bread() into a vmalloc()ed
- memory buffer).
- - Enable compressed directories. (Their index root is marked compressed
- to indicate that new files in that directory should be created
- compressed.)
- - Use vsnprintf rather than vsprintf in the ntfs_error and ntfs_warning
- functions. (Thanks to Will Dyson for pointing this out.)
- - Moved the ntfs_inode and ntfs_volume (the former ntfs_inode_info and
- ntfs_sb_info) out of the common inode and super_block structures and
- started using the generic_ip and generic_sbp pointers instead. This
- makes ntfs entirely private with respect to the kernel tree.
- - Detect compiler version and abort with error message if gcc less than
- 2.96 is used.
- - Fix bug in name comparison function in unistr.c.
- - Implement attribute lists part 1, the infrastructure: search contexts
- and operations, find_external_attr(), lookup_attr()) and make the
- code use the infrastructure.
- - Fix stupid buffer overflow bug that became apparent on larger run
- list containing attributes.
- - Fix bugs in readdir() that became apparent on larger directories.
-
- The driver is now really useful and survives the test
- find . -type f -exec md5sum "{}" \;
- without any error messages on a over 1GiB sized partition with >16k
- files on it, including compressed files and directories and many files
- and directories with attribute lists.
-
-tng-0.0.1 - The first useful version.
-
- - Added ntfs_lookup().
- - Added default upcase generation and handling.
- - Added compile options to be shown on module init.
- - Many bug fixes that were "hidden" before.
- - Update to latest kernel.
- - Added ntfs_readdir().
- - Added file operations for mmap(), read(), open() and llseek(). We just
- use the generic ones. The whole point of going through implementing
- readpage() methods and where possible get_block() call backs is that
- this allows us to make use of the generic high level methods provided
- by the kernel.
-
- The driver is now actually useful! Yey. (-: It undoubtedly has got bugs
- though and it doesn't implement accesssing compressed files yet. Also,
- accessing files with attribute list attributes is not implemented yet
- either. But for small or simple filesystems it should work and allow
- you to list directories, use stat on directory entries and the file
- system, open, read, mmap and llseek around in files. A big mile stone
- has been reached!
-
-tng-0.0.0 - Initial version tag.
-
- Initial driver implementation. The driver can mount and umount simple
- NTFS filesystems (i.e. ones without attribute lists in the system
- files). If the mount fails there might be problems in the error handling
- code paths, so be warned. Otherwise it seems to be loading the system
- files nicely and the mft record read mapping/unmapping seems to be
- working nicely, too. Proof of inode metadata in the page cache and non-
- resident file unnamed stream data in the page cache concepts is thus
- complete.

+/**
+ * DOC: B+Tree basics
+ *
+ * A B+Tree is a data structure for looking up arbitrary (currently allowing
+ * unsigned long, u32, u64 and 2 * u64) keys into pointers. The data structure
+ * is described at http://en.wikipedia.org/wiki/B-tree, we currently do not
+ * use binary search to find the key on lookups.
+ *
+ * Each B+Tree consists of a head, that contains bookkeeping information and
+ * a variable number (starting with zero) nodes. Each node contains the keys
+ * and pointers to sub-nodes, or, for leaf nodes, the keys and values for the
+ * tree entries.
+ *
+ * Each node in this implementation has the following layout:
+ * [key1, key2, ..., keyN] [val1, val2, ..., valN]
+ *
+ * Each key here is an array of unsigned longs, geo->no_longs in total. The
+ * number of keys and values (N) is geo->no_pairs.

- * The vstusb module is a standard usb 'client' driver running on top of the

- *
- * In general, vstusb supports standard bulk usb pipes. It supports multiple
- * devices and multiple pipes per device.
- *
- * The vstusb driver supports two interfaces:
- * 1 - ioctl SEND_PIPE/RECV_PIPE - a general bulk write/read msg
- * interface to any pipe with timeout support;
- * 2 - standard read/write with ioctl config - offers standard read/write
- * interface with ioctl configured pipes and timeouts.
- *
- * Both interfaces can be signal from other process and will abort its i/o
- * operation.
- *
- * A timeout of 0 means NO timeout. The user can still terminate the read via
- * signal.
- *
- * If using multiple threads with this driver, the user should ensure that
- * any reads, writes, or ioctls are complete before closing the device.
- * Changing read/write timeouts or pipes takes effect on next read/write.

+ * A relatively simple B+Tree implementation. I have written it as a learning
+ * excercise to understand how B+Trees work. Turned out to be useful as well.
+ *
+ * B+Trees can be used similar to Linux radix trees (which don't have anything
+ * in common with textbook radix trees, beware). Prerequisite for them working
+ * well is that access to a random tree node is much faster than a large number
+ * of operations within each node.
+ *
+ * Disks have fulfilled the prerequisite for a long time. More recently DRAM
+ * has gained similar properties, as memory access times, when measured in cpu
+ * cycles, have increased. Cacheline sizes have increased as well, which also
+ * helps B+Trees.
+ *
+ * Compared to radix trees, B+Trees are more efficient when dealing with a
+ * sparsely populated address space. Between 25% and 50% of the memory is
+ * occupied with valid pointers. When densely populated, radix trees contain
+ * ~98% pointers - hard to beat. Very sparse radix trees contain only ~2%
+ * pointers.
+ *
+ * This particular implementation stores pointers identified by a long value.
+ * Storing NULL pointers is illegal, lookup will return NULL when no entry
+ * was found.
+ *
+ * A tricks was used that is not commonly found in textbooks. The lowest
+ * values are to the right, not to the left. All used slots within a node
+ * are on the left, all unused slots contain NUL values. Most operations
+ * simply loop once over all slots and terminate on the first NUL.

+ The "Communication CPU to Application CPU Interface" (CAIF) is a packet

+ with its modems. It is accessed from user space as sockets (PF_CAIF).
+
+ Say Y (or M) here if you build for a phone product (e.g. Android or
+ MeeGo ) that uses CAIF as transport, if unsure say N.
+
+ If you select to build it as module then CAIF_NETDEV also needs to be
+ built as modules. You will also need to say yes to any CAIF physical
+ devices that your platform requires.
+
+ See Documentation/networking/caif for a further explanation on how to

+ Layer Two Tunneling Protocol
+
+ From RFC 2661 <http://www.ietf.org/rfc/rfc2661.txt>.
+
+ L2TP facilitates the tunneling of packets across an
+ intervening network in a way that is as transparent as
+ possible to both end-users and applications.
+
+ L2TP is often used to tunnel PPP traffic over IP
+ tunnels. One IP tunnel may carry thousands of individual PPP
+ connections. L2TP is also used as a VPN protocol, popular
+ with home workers to connect to their offices.
+
+ L2TPv3 allows other protocols as well as PPP to be carried
+ over L2TP tunnels. L2TPv3 is defined in RFC 3931
+ <http://www.ietf.org/rfc/rfc3931.txt>.
+
+ The kernel component handles only L2TP data packets: a
+ userland daemon handles L2TP the control protocol (tunnel
+ and session setup). One such daemon is OpenL2TP
+ (http://openl2tp.org/).
+
+ If you don't need L2TP, say N. To compile all L2TP code as
+ modules, choose M here.

+ Layer Two Tunneling Protocol Version 3
+
+ From RFC 3931 <http://www.ietf.org/rfc/rfc3931.txt>.
+
+ The Layer Two Tunneling Protocol (L2TP) provides a dynamic
+ mechanism for tunneling Layer 2 (L2) "circuits" across a
+ packet-oriented data network (e.g., over IP). L2TP, as
+ originally defined in RFC 2661, is a standard method for
+ tunneling Point-to-Point Protocol (PPP) [RFC1661] sessions.
+ L2TP has since been adopted for tunneling a number of other
+ L2 protocols, including ATM, Frame Relay, HDLC and even raw
+ ethernet frames.
+
+ If you are connecting to L2TPv3 equipment, or you want to
+ tunnel raw ethernet frames using L2TP, say Y here. If
+ unsure, say N.
+
+config L2TP_IP
+ tristate "L2TP IP encapsulation for L2TPv3"
+ depends on L2TP_V3
+ help
+ Support for L2TP-over-IP socket family.
+
+ The L2TPv3 protocol defines two possible encapsulations for
+ L2TP frames, namely UDP and plain IP (without UDP). This
+ driver provides a new L2TPIP socket family with which
+ userspace L2TPv3 daemons may create L2TP/IP tunnel sockets
+ when UDP encapsulation is not required. When L2TP is carried
+ in IP packets, it used IP protocol number 115, so this port
+ must be enabled in firewalls.
+
+ To compile this driver as a module, choose M here. The module
+ will be called l2tp_ip.
+
+config L2TP_ETH
+ tristate "L2TP ethernet pseudowire support for L2TPv3"
+ depends on L2TP_V3
+ help
+ Support for carrying raw ethernet frames over L2TPv3.
+
+ From RFC 4719 <http://www.ietf.org/rfc/rfc4719.txt>.
+
+ The Layer 2 Tunneling Protocol, Version 3 (L2TPv3) can be
+ used as a control protocol and for data encapsulation to set
+ up Pseudowires for transporting layer 2 Packet Data Units
+ across an IP network [RFC3931].
+
+ This driver provides an ethernet virtual interface for each
+ L2TP ethernet pseudowire instance. Standard Linux tools may
+ be used to assign an IP address to the local virtual
+ interface, or add the interface to a bridge.
+
+ If you are using L2TPv3, you will almost certainly want to
+ enable this option.
+
+ To compile this driver as a module, choose M here. The module
+ will be called l2tp_eth.

+ * Linux PPP over L2TP (PPPoX/PPPoL2TP) Sockets

+ * PPPoX --- Generic PPP encapsulation socket family
+ * PPPoL2TP --- PPP over L2TP (RFC 2661)

+
+/* This driver handles only L2TP data frames; control frames are handled by a
+ * userspace application.
+ *
+ * To send data in an L2TP session, userspace opens a PPPoL2TP socket and
+ * attaches it to a bound UDP socket with local tunnel_id / session_id and
+ * peer tunnel_id / session_id set. Data can then be sent or received using
+ * regular socket sendmsg() / recvmsg() calls. Kernel parameters of the socket
+ * can be read or modified using ioctl() or [gs]etsockopt() calls.
+ *
+ * When a PPPoL2TP socket is connected with local and peer session_id values
+ * zero, the socket is treated as a special tunnel management socket.
+ *
+ * Here's example userspace code to create a socket for sending/receiving data
+ * over an L2TP session:-
+ *
+ * struct sockaddr_pppol2tp sax;
+ * int fd;
+ * int session_fd;
+ *
+ * fd = socket(AF_PPPOX, SOCK_DGRAM, PX_PROTO_OL2TP);
+ *
+ * sax.sa_family = AF_PPPOX;
+ * sax.sa_protocol = PX_PROTO_OL2TP;
+ * sax.pppol2tp.fd = tunnel_fd; // bound UDP socket
+ * sax.pppol2tp.addr.sin_addr.s_addr = addr->sin_addr.s_addr;
+ * sax.pppol2tp.addr.sin_port = addr->sin_port;
+ * sax.pppol2tp.addr.sin_family = AF_INET;
+ * sax.pppol2tp.s_tunnel = tunnel_id;
+ * sax.pppol2tp.s_session = session_id;
+ * sax.pppol2tp.d_tunnel = peer_tunnel_id;
+ * sax.pppol2tp.d_session = peer_session_id;
+ *
+ * session_fd = connect(fd, (struct sockaddr *)&sax, sizeof(sax));
+ *
+ * A pppd plugin that allows PPP traffic to be carried over L2TP using
+ * this driver is available from the OpenL2TP project at
+ * http://openl2tp.sourceforge.net.

+
+SYNOPSIS
+--------
+[verse]
+'perf lock' {record|report|trace}
+
+DESCRIPTION
+-----------
+You can analyze various lock behaviours
+and statistics with this 'perf lock' command.
+
+ 'perf lock record <command>' records lock events
+ between start and end <command>. And this command
+ produces the file "perf.data" which contains tracing
+ results of lock events.
+
+ 'perf lock trace' shows raw lock events.
+
+ 'perf lock report' reports statistical data.

PROBE SYNTAX
------------
Probe points are defined by following syntax.
- "[EVENT=]FUNC[+OFFS|:RLN|%return][@SRC]|SRC:ALN [ARG ...]"
+ 1) Define event based on function name
+ [EVENT=]FUNC[@SRC][:RLN|+OFFS|%return|;PTN] [ARG ...]
+
+ 2) Define event based on source file with line number
+ [EVENT=]SRC:ALN [ARG ...]
+
+ 3) Define event based on source file with lazy pattern
+ [EVENT=]SRC;PTN [ARG ...]
+
'EVENT' specifies the name of new event, if omitted, it will be set the name of the probed function. Currently, event group name is set as 'probe'.
-'FUNC' specifies a probed function name, and it may have one of the following options; '+OFFS' is the offset from function entry address in bytes, 'RLN' is the relative-line number from function entry line, and '%return' means that it probes function return. In addition, 'SRC' specifies a source file which has that function.
-It is also possible to specify a probe point by the source line number by using 'SRC:ALN' syntax, where 'SRC' is the source file path and 'ALN' is the line number.
+'FUNC' specifies a probed function name, and it may have one of the following options; '+OFFS' is the offset from function entry address in bytes, ':RLN' is the relative-line number from function entry line, and '%return' means that it probes function return. And ';PTN' means lazy matching pattern (see LAZY MATCHING). Note that ';PTN' must be the end of the probe point definition. In addition, '@SRC' specifies a source file which has that function.
+It is also possible to specify a probe point by the source line number or lazy matching by using 'SRC:ALN' or 'SRC;PTN' syntax, where 'SRC' is the source file path, ':ALN' is the line number and ';PTN' is the lazy matching pattern.
'ARG' specifies the arguments of this probe point. You can use the name of local variable, or kprobe-tracer argument format (e.g. $retval, %ax, etc).
LINE SYNTAX
@@ -76,6 +89,41 @@
many lines to show by using 'NUM'.
So, "source.c:100-120" shows lines between 100th to l20th in source.c file. And "func:10+20" shows 20 lines from 10th line of func function.
+LAZY MATCHING
+-------------
+ The lazy line matching is similar to glob matching but ignoring spaces in both of pattern and target. So this accepts wildcards('*', '?') and character classes(e.g. [a-z], [!A-Z]).
+
+e.g.
+ 'a=*' can matches 'a=b', 'a = b', 'a == b' and so on.
+
+This provides some sort of flexibility and robustness to probe point definitions against minor code changes. For example, actual 10th line of schedule() can be moved easily by modifying schedule(), but the same line matching 'rq=cpu_rq*' may still exist in the function.)
+
+
+EXAMPLES
+--------
+Display which lines in schedule() can be probed:
+
+ ./perf probe --line schedule
+
+Add a probe on schedule() function 12th line with recording cpu local variable:
+
+ ./perf probe schedule:12 cpu
+ or
+ ./perf probe --add='schedule:12 cpu'
+
+ this will add one or more probes which has the name start with "schedule".
+
+ Add probes on lines in schedule() function which calls update_rq_clock().
+
+ ./perf probe 'schedule;update_rq_clock*'
+ or
+ ./perf probe --add='schedule;update_rq_clock*'
+
+Delete all probes on schedule().
+
+ ./perf probe --del='schedule*'
