+ 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.

- 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.
- */
- }
-

-form without the feedback and suggestions from numerous individuals.

+
+ 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.

+--------------------
+
+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.

+ 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.
+
+
+Contents:
+
+ (*) What is a circular buffer?
+
+ (*) Measuring power-of-2 buffers.
+
+ (*) Using memory barriers with circular buffers.
+ - The producer.
+ - 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.

+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.)

+ 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.
+
+struct plat_stmmacenet_data {
+ int bus_id;
+ int pbl;
+ int has_gmac;

+ void (*bus_setup)(unsigned long ioaddr);
+#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);
+ 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.

+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.

+Filter commands
+---------------
+
+A few commands are supported by the set_ftrace_filter interface.
+Trace commands have the following format:
+
+<function>:<command>:<parameter>
+
+The following commands are supported:
+
+- mod
+ This command enables function filtering per module. The
+ parameter defines the module. For example, if only the write*
+ functions in the ext3 module are desired, run:
+
+ echo 'write*:mod:ext3' > set_ftrace_filter
+
+ This command interacts with the filter in the same way as
+ filtering based on function names. Thus, adding more functions
+ in a different module is accomplished by appending (>>) to the
+ filter file. Remove specific module functions by prepending
+ '!':
+
+ echo '!writeback*:mod:ext3' >> set_ftrace_filter
+
+- traceon/traceoff
+ These commands turn tracing on and off when the specified
+ functions are hit. The parameter determines how many times the
+ tracing system is turned on and off. If unspecified, there is
+ no limit. For example, to disable tracing when a schedule bug
+ is hit the first 5 times, run:
+
+ echo '__schedule_bug:traceoff:5' > set_ftrace_filter
+
+ These commands are cumulative whether or not they are appended
+ to set_ftrace_filter. To remove a command, prepend it by '!'
+ and drop the parameter:
+
+ echo '!__schedule_bug:traceoff' > set_ftrace_filter

-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.

- * { SFN => IN } Change CON first
- * { SFN => OUT } Change DAT first, so new data will not glitch [1]

- 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.

+ * 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

+ -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
+
+ Loongson 2F03 and later have fixed these issues and no workarounds
+ are needed. The workarounds have no significant side effect on them
+ but may decrease the performance of the system so this option should
+ be disabled unless the kernel is intended to be run on 2F01 or 2F02
+ systems.

- * The power_pmu.get_constraint function returns a 32/64-bit value and

- *
- * The value and mask are divided up into (non-overlapping) bitfields
- * of three different types:
- *
- * Select field: this expresses the constraint that some set of bits
- * in MMCR* needs to be set to a specific value for this event_id. For a
- * select field, the mask contains 1s in every bit of the field, and
- * the value contains a unique value for each possible setting of the
- * MMCR* bits. The constraint checking code will ensure that two events
- * that set the same field in their masks have the same value in their
- * value dwords.
- *
- * Add field: this expresses the constraint that there can be at most
- * N events in a particular class. A field of k bits can be used for
- * N <= 2^(k-1) - 1. The mask has the most significant bit of the field
- * set (and the other bits 0), and the value has only the least significant
- * bit of the field set. In addition, the 'add_fields' and 'test_adder'
- * in the struct power_pmu for this processor come into play. The
- * add_fields value contains 1 in the LSB of the field, and the
- * test_adder contains 2^(k-1) - 1 - N in the field.
- *
- * NAND field: this expresses the constraint that you may not have events
- * in all of a set of classes. (For example, on PPC970, you can't select
- * events from the FPU, ISU and IDU simultaneously, although any two are
- * possible.) For N classes, the field is N+1 bits wide, and each class
- * is assigned one bit from the least-significant N bits. The mask has
- * only the most-significant bit set, and the value has only the bit
- * for the event_id's class set. The test_adder has the least significant
- * bit set in the field.
- *
- * If an event_id is not subject to the constraint expressed by a particular
- * field, then it will have 0 in both the mask and value for that field.

+ *
+ * The value and mask are divided up into (non-overlapping) bitfields
+ * of three different types:
+ *
+ * Select field: this expresses the constraint that some set of bits
+ * in MMCR* needs to be set to a specific value for this event_id. For a
+ * select field, the mask contains 1s in every bit of the field, and
+ * the value contains a unique value for each possible setting of the
+ * MMCR* bits. The constraint checking code will ensure that two events
+ * that set the same field in their masks have the same value in their
+ * value dwords.
+ *
+ * Add field: this expresses the constraint that there can be at most
+ * N events in a particular class. A field of k bits can be used for
+ * N <= 2^(k-1) - 1. The mask has the most significant bit of the field
+ * set (and the other bits 0), and the value has only the least significant
+ * bit of the field set. In addition, the 'add_fields' and 'test_adder'
+ * in the struct power_pmu for this processor come into play. The
+ * add_fields value contains 1 in the LSB of the field, and the
+ * test_adder contains 2^(k-1) - 1 - N in the field.
+ *
+ * NAND field: this expresses the constraint that you may not have events
+ * in all of a set of classes. (For example, on PPC970, you can't select
+ * events from the FPU, ISU and IDU simultaneously, although any two are
+ * possible.) For N classes, the field is N+1 bits wide, and each class
+ * is assigned one bit from the least-significant N bits. The mask has
+ * only the most-significant bit set, and the value has only the bit
+ * for the event_id's class set. The test_adder has the least significant
+ * bit set in the field.
+ *
+ * If an event_id is not subject to the constraint expressed by a particular
+ * field, then it will have 0 in both the mask and value for that field.

- * TBD:
- * 1. Make # power states dynamic.
- * 2. Support duty_cycle values that span bit 4.
- * 3. Optimize by having scheduler determine business instead of
- * having us try to calculate it here.
- * 4. Need C1 timing -- must modify kernel (IRQ handler) to get this.

- * 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.)

-
- * ieee1284_ops.c (parport_ieee1284_write_compat): Don't use
- down_trylock to reset the IRQ count. Don't even use sema_init,
- because it's not even necessary to reset the count. I can't
- remember why we ever did.

+ * 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
+ * write completes (or fails) and a final size/mtime for the inode for
+ * that snap can be settled upon.) i_wrbuffer_ref_head is reset to 0.
+ *
+ * On writeback, we must submit writes to the osd IN SNAP ORDER. So,
+ * we look for the first capsnap in i_cap_snaps and write out pages in
+ * that snap context _only_. Then we move on to the next capsnap,
+ * eventually reaching the "live" or "head" context (i.e., pages that
+ * are not yet snapped) and are writing the most recently dirtied
+ * pages.
+ *
+ * Invalidate and so forth must take care to ensure the dirty page
+ * accounting is preserved.

+ *
+ * If the client holds a *_SHARED cap, the client has a coherent value

+ * In the case of a *_EXCL (exclusive) or FILE_WR capabilities, 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

+ * 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.

-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.

+perf-inject - Filter to augment the events stream with additional information
+
+SYNOPSIS
+--------
+[verse]
+'perf inject <options>'
+
+DESCRIPTION
+-----------
+perf-inject reads a perf-record event stream and repipes it to stdout. At any
+point the processing code can inject other events into the event stream - in
+this case build-ids (-b option) are read and injected as needed into the event
+stream.
+
+Build-ids are just the first user of perf-inject - potentially anything that
+needs userspace processing to augment the events stream with additional
+information could make use of this facility.
+
+OPTIONS
+-------
+-b::
+--build-ids=::
+ Inject build-ids into the output stream
+-v::
+--verbose::
+ Be more verbose.

+perf-kvm - Tool to trace/measure kvm guest os
+
+SYNOPSIS
+--------
+[verse]
+'perf kvm' [--host] [--guest] [--guestmount=<path>
+ [--guestkallsyms=<path> --guestmodules=<path> | --guestvmlinux=<path>]]
+ {top|record|report|diff|buildid-list}
+'perf kvm' [--host] [--guest] [--guestkallsyms=<path> --guestmodules=<path>
+ | --guestvmlinux=<path>] {top|record|report|diff|buildid-list}
+
+DESCRIPTION
+-----------
+There are a couple of variants of perf kvm:
+
+ 'perf kvm [options] top <command>' to generates and displays
+ a performance counter profile of guest os in realtime
+ of an arbitrary workload.
+
+ 'perf kvm record <command>' to record the performance couinter profile
+ of an arbitrary workload and save it into a perf data file. If both
+ --host and --guest are input, the perf data file name is perf.data.kvm.
+ If there is no --host but --guest, the file name is perf.data.guest.
+ If there is no --guest but --host, the file name is perf.data.host.
+
+ 'perf kvm report' to display the performance counter profile information
+ recorded via perf kvm record.
+
+ 'perf kvm diff' to displays the performance difference amongst two perf.data
+ files captured via perf record.
+
+ 'perf kvm buildid-list' to display the buildids found in a perf data file,
+ so that other tools can be used to fetch packages with matching symbol tables
+ for use by perf report.
+
+OPTIONS
+-------
+--host=::
+ Collect host side performance profile.
+--guest=::
+ Collect guest side performance profile.
+--guestmount=<path>::
+ Guest os root file system mount directory. Users mounts guest os
+ root directories under <path> by a specific filesystem access method,
+ typically, sshfs. For example, start 2 guest os. The one's pid is 8888
+ and the other's is 9999.
+ #mkdir ~/guestmount; cd ~/guestmount
+ #sshfs -o allow_other,direct_io -p 5551 localhost:/ 8888/
+ #sshfs -o allow_other,direct_io -p 5552 localhost:/ 9999/
+ #perf kvm --host --guest --guestmount=~/guestmount top
+--guestkallsyms=<path>::
+ Guest os /proc/kallsyms file copy. 'perf' kvm' reads it to get guest
+ kernel symbols. Users copy it out from guest os.
+--guestmodules=<path>::
+ Guest os /proc/modules file copy. 'perf' kvm' reads it to get guest
+ kernel module information. Users copy it out from guest os.
+--guestvmlinux=<path>::
+ Guest os kernel vmlinux.

This command displays the symbolic event types which can be selected in the
various perf commands with the -e option.
+RAW HARDWARE EVENT DESCRIPTOR
+-----------------------------
+Even when an event is not available in a symbolic form within perf right now,
+it can be encoded in a per processor specific way.
+
+For instance For x86 CPUs NNN represents the raw register encoding with the
+layout of IA32_PERFEVTSELx MSRs (see [Intel® 64 and IA-32 Architectures Software Developer's Manual Volume 3B: System Programming Guide] Figure 30-1 Layout
+of IA32_PERFEVTSELx MSRs) or AMD's PerfEvtSeln (see [AMD64 Architecture Programmer’s Manual Volume 2: System Programming], Page 344,
+Figure 13-7 Performance Event-Select Register (PerfEvtSeln)).
+
+Example:
+
+If the Intel docs for a QM720 Core i7 describe an event as:
+
+ Event Umask Event Mask
+ Num. Value Mnemonic Description Comment
+
+ A8H 01H LSD.UOPS Counts the number of micro-ops Use cmask=1 and
+ delivered by loop stream detector invert to count
+ cycles
+
+raw encoding of 0x1A8 can be used:
+
+ perf stat -e r1a8 -a sleep 1
+ perf record -e r1a8 ...
+
+You should refer to the processor specific documentation for getting these
+details. Some of them are referenced in the SEE ALSO section below.

+[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.
@@ -74,13 +82,22 @@
'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. 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. $retval, %ax, etc).
+'ARG' specifies the arguments of this probe point, (see PROBE ARGUMENT).
+
+PROBE ARGUMENT
+--------------
+Each probe argument follows below syntax.
+
+ [NAME=]LOCALVAR|$retval|%REG|@SYMBOL[:TYPE]
+
+'NAME' specifies the name of this argument (optional). You can use the name of local variable, local data structure member (e.g. var->field, var.field2), or kprobe-tracer argument format (e.g. $retval, %ax, etc). Note that the name of this argument will be set as the last member name if you specify a local data structure member (e.g. field2 for 'var->field1.field2'.)
+'TYPE' casts the type of this argument (optional). If omitted, perf probe automatically set the type based on debuginfo.
LINE SYNTAX
-----------
Line range is descripted by following syntax.
- "FUNC[:RLN[+NUM|:RLN2]]|SRC:ALN[+NUM|:ALN2]"
+ "FUNC[:RLN[+NUM|-RLN2]]|SRC:ALN[+NUM|-ALN2]"
FUNC specifies the function name of showing lines. 'RLN' is the start line
number from function entry line, and 'RLN2' is the end line number. As same as
