+Linux kernel style for use of spaces depends (mostly) on

+somewhat like functions (and are usually used with parentheses in Linux,

+ <title>Details</title>
+<para>
+The journalling layer is easy to use. You need to
+first of all create a journal_t data structure. There are
+two calls to do this dependent on how you decide to allocate the physical
+media on which the journal resides. The journal_init_inode() call
+is for journals stored in filesystem inodes, or the journal_init_dev()
+call can be use for journal stored on a raw device (in a continuous range
+of blocks). A journal_t is a typedef for a struct pointer, so when
+you are finally finished make sure you call journal_destroy() on it
+to free up any used kernel memory.
+</para>
+
+<para>
+Once you have got your journal_t object you need to 'mount' or load the journal
+file, unless of course you haven't initialised it yet - in which case you
+need to call journal_create().
+</para>
+
+<para>
+Most of the time however your journal file will already have been created, but
+before you load it you must call journal_wipe() to empty the journal file.
+Hang on, you say , what if the filesystem wasn't cleanly umount()'d . Well, it is the
+job of the client file system to detect this and skip the call to journal_wipe().
+</para>
+
+<para>
+In either case the next call should be to journal_load() which prepares the
+journal file for use. Note that journal_wipe(..,0) calls journal_skip_recovery()
+for you if it detects any outstanding transactions in the journal and similarly
+journal_load() will call journal_recover() if necessary.
+I would advise reading fs/ext3/super.c for examples on this stage.
+[RGG: Why is the journal_wipe() call necessary - doesn't this needlessly
+complicate the API. Or isn't a good idea for the journal layer to hide
+dirty mounts from the client fs]
+</para>
+
+<para>
+Now you can go ahead and start modifying the underlying
+filesystem. Almost.
+</para>
+
+<para>
+
+You still need to actually journal your filesystem changes, this
+is done by wrapping them into transactions. Additionally you
+also need to wrap the modification of each of the buffers
+with calls to the journal layer, so it knows what the modifications
+you are actually making are. To do this use journal_start() which
+returns a transaction handle.
+</para>
+
+<para>
+journal_start()
+and its counterpart journal_stop(), which indicates the end of a transaction
+are nestable calls, so you can reenter a transaction if necessary,
+but remember you must call journal_stop() the same number of times as
+journal_start() before the transaction is completed (or more accurately
+leaves the update phase). Ext3/VFS makes use of this feature to simplify
+quota support.
+</para>
+
+<para>
+Inside each transaction you need to wrap the modifications to the
+individual buffers (blocks). Before you start to modify a buffer you
+need to call journal_get_{create,write,undo}_access() as appropriate,
+this allows the journalling layer to copy the unmodified data if it
+needs to. After all the buffer may be part of a previously uncommitted
+transaction.
+At this point you are at last ready to modify a buffer, and once
+you are have done so you need to call journal_dirty_{meta,}data().
+Or if you've asked for access to a buffer you now know is now longer
+required to be pushed back on the device you can call journal_forget()
+in much the same way as you might have used bforget() in the past.
+</para>
+
+<para>
+A journal_flush() may be called at any time to commit and checkpoint
+all your transactions.
+</para>
+
+<para>
+Then at umount time , in your put_super() (2.4) or write_super() (2.5)
+you can then call journal_destroy() to clean up your in-core journal object.
+</para>
+
+<para>
+Unfortunately there a couple of ways the journal layer can cause a deadlock.
+The first thing to note is that each task can only have
+a single outstanding transaction at any one time, remember nothing
+commits until the outermost journal_stop(). This means
+you must complete the transaction at the end of each file/inode/address
+etc. operation you perform, so that the journalling system isn't re-entered
+on another journal. Since transactions can't be nested/batched
+across differing journals, and another filesystem other than
+yours (say ext3) may be modified in a later syscall.
+</para>
+
+<para>
+The second case to bear in mind is that journal_start() can
+block if there isn't enough space in the journal for your transaction
+(based on the passed nblocks param) - when it blocks it merely(!) needs to
+wait for transactions to complete and be committed from other tasks,
+so essentially we are waiting for journal_stop(). So to avoid
+deadlocks you must treat journal_start/stop() as if they
+were semaphores and include them in your semaphore ordering rules to prevent
+deadlocks. Note that journal_extend() has similar blocking behaviour to
+journal_start() so you can deadlock here just as easily as on journal_start().
+</para>
+
+<para>
+Try to reserve the right number of blocks the first time. ;-). This will
+be the maximum number of blocks you are going to touch in this transaction.
+I advise having a look at at least ext3_jbd.h to see the basis on which
+ext3 uses to make these decisions.
+</para>
+
+<para>
+Another wriggle to watch out for is your on-disk block allocation strategy.
+why? Because, if you undo a delete, you need to ensure you haven't reused any
+of the freed blocks in a later transaction. One simple way of doing this
+is make sure any blocks you allocate only have checkpointed transactions
+listed against them. Ext3 does this in ext3_test_allocatable().
+</para>
+
+<para>
+Lock is also providing through journal_{un,}lock_updates(),
+ext3 uses this when it wants a window with a clean and stable fs for a moment.
+eg.
+</para>
+
+<programlisting>
+
+ journal_lock_updates() //stop new stuff happening..
+ journal_flush() // checkpoint everything.
+ ..do stuff on stable fs
+ journal_unlock_updates() // carry on with filesystem use.
+</programlisting>
+
+<para>
+The opportunities for abuse and DOS attacks with this should be obvious,
+if you allow unprivileged userspace to trigger codepaths containing these
+calls.
+</para>
+
+<para>
+A new feature of jbd since 2.5.25 is commit callbacks with the new
+journal_callback_set() function you can now ask the journalling layer
+to call you back when the transaction is finally committed to disk, so that
+you can do some of your own management. The key to this is the journal_callback
+struct, this maintains the internal callback information but you can
+extend it like this:-
+</para>
+<programlisting>
+ struct myfs_callback_s {
+ //Data structure element required by jbd..
+ struct journal_callback for_jbd;
+ // Stuff for myfs allocated together.
+ myfs_inode* i_commited;
+
+ }
+</programlisting>

+this would be useful if you needed to know when data was committed to a
+particular inode.

- <title>Details</title>
-<para>
-The journalling layer is easy to use. You need to
-first of all create a journal_t data structure. There are
-two calls to do this dependent on how you decide to allocate the physical
-media on which the journal resides. The journal_init_inode() call
-is for journals stored in filesystem inodes, or the journal_init_dev()
-call can be use for journal stored on a raw device (in a continuous range
-of blocks). A journal_t is a typedef for a struct pointer, so when
-you are finally finished make sure you call journal_destroy() on it
-to free up any used kernel memory.
-</para>
-
-<para>
-Once you have got your journal_t object you need to 'mount' or load the journal
-file, unless of course you haven't initialised it yet - in which case you
-need to call journal_create().
-</para>
-
-<para>
-Most of the time however your journal file will already have been created, but
-before you load it you must call journal_wipe() to empty the journal file.
-Hang on, you say , what if the filesystem wasn't cleanly umount()'d . Well, it is the
-job of the client file system to detect this and skip the call to journal_wipe().
-</para>
-
-<para>
-In either case the next call should be to journal_load() which prepares the
-journal file for use. Note that journal_wipe(..,0) calls journal_skip_recovery()
-for you if it detects any outstanding transactions in the journal and similarly
-journal_load() will call journal_recover() if necessary.
-I would advise reading fs/ext3/super.c for examples on this stage.
-[RGG: Why is the journal_wipe() call necessary - doesn't this needlessly
-complicate the API. Or isn't a good idea for the journal layer to hide
-dirty mounts from the client fs]
-</para>
-
-<para>
-Now you can go ahead and start modifying the underlying
-filesystem. Almost.
-</para>
-
-
-<para>
-
-You still need to actually journal your filesystem changes, this
-is done by wrapping them into transactions. Additionally you
-also need to wrap the modification of each of the buffers
-with calls to the journal layer, so it knows what the modifications
-you are actually making are. To do this use journal_start() which
-returns a transaction handle.
-</para>
-
-<para>
-journal_start()
-and its counterpart journal_stop(), which indicates the end of a transaction
-are nestable calls, so you can reenter a transaction if necessary,
-but remember you must call journal_stop() the same number of times as
-journal_start() before the transaction is completed (or more accurately
-leaves the update phase). Ext3/VFS makes use of this feature to simplify

+Managing bug reports
+--------------------
+
+One of the best ways to put into practice your hacking skills is by fixing
+bugs reported by other people. Not only you will help to make the kernel
+more stable, you'll learn to fix real world problems and you will improve
+your skills, and other developers will be aware of your presence. Fixing
+bugs is one of the best ways to get merits among other developers, because
+not many people like wasting time fixing other people's bugs.
+
+To work in the already reported bug reports, go to http://bugzilla.kernel.org.
+If you want to be advised of the future bug reports, you can subscribe to the
+bugme-new mailing list (only new bug reports are mailed here) or to the
+bugme-janitor mailing list (every change in the bugzilla is mailed here)

-6. FAQ
+6. MSI quirks
+
+Several PCI chipsets or devices are known to not support MSI.
+The PCI stack provides 3 possible levels of MSI disabling:
+* on a single device
+* on all devices behind a specific bridge
+* globally
+
+6.1. Disabling MSI on a single device
+
+Under some circumstances, it might be required to disable MSI on a
+single device, It may be achived by either not calling pci_enable_msi()
+or all, or setting the pci_dev->no_msi flag before (most of the time
+in a quirk).
+
+6.2. Disabling MSI below a bridge
+
+The vast majority of MSI quirks are required by PCI bridges not
+being able to route MSI between busses. In this case, MSI have to be
+disabled on all devices behind this bridge. It is achieves by setting
+the PCI_BUS_FLAGS_NO_MSI flag in the pci_bus->bus_flags of the bridge
+subordinate bus. There is no need to set the same flag on bridges that
+are below the broken brigde. When pci_enable_msi() is called to enable
+MSI on a device, pci_msi_supported() takes care of checking the NO_MSI
+flag in all parent busses of the device.
+
+Some bridges actually support dynamic MSI support enabling/disabling
+by changing some bits in their PCI configuration space (especially
+the Hypertransport chipsets such as the nVidia nForce and Serverworks
+HT2000). It may then be required to update the NO_MSI flag on the
+corresponding devices in the sysfs hierarchy. To enable MSI support
+on device "0000:00:0e", do:
+
+ echo 1 > /sys/bus/pci/devices/0000:00:0e/msi_bus
+
+To disable MSI support, echo 0 instead of 1. Note that it should be
+used with caution since changing this value might break interrupts.
+
+6.3. Disabling MSI globally
+
+Some extreme cases may require to disable MSI globally on the system.
+For now, the only known case is a Serverworks PCI-X chipsets (MSI are
+not supported on several busses that are not all connected to the
+chipset in the Linux PCI hierarchy). In the vast majority of other
+cases, disabling only behind a specific bridge is enough.
+
+For debugging purpose, the user may also pass pci=nomsi on the kernel
+command-line to explicitly disable MSI globally. But, once the appro-
+priate quirks are added to the kernel, this option should not be
+required anymore.
+
+6.4. Finding why MSI cannot be enabled on a device
+
+Assuming that MSI are not enabled on a device, you should look at
+dmesg to find messages that quirks may output when disabling MSI
+on some devices, some bridges or even globally.
+Then, lspci -t gives the list of bridges above a device. Reading
+/sys/bus/pci/devices/0000:00:0e/msi_bus will tell you whether MSI
+are enabled (1) or disabled (0). In 0 is found in a single bridge
+msi_bus file above the device, MSI cannot be enabled.
+
+7. FAQ

Platform Devices and Drivers
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+See <linux/platform_device.h> for the driver model interface to the
+platform bus: platform_device, and platform_driver. This pseudo-bus
+is used to connect devices on busses with minimal infrastructure,
+like those used to integrate peripherals on many system-on-chip
+processors, or some "legacy" PC interconnects; as opposed to large
+formally specified ones like PCI or USB.
+
Platform devices
~~~~~~~~~~~~~~~~
Platform devices are devices that typically appear as autonomous
entities in the system. This includes legacy port-based devices and
-host bridges to peripheral buses.
+host bridges to peripheral buses, and most controllers integrated
+into system-on-chip platforms. What they usually have in common
+is direct addressing from a CPU bus. Rarely, a platform_device will
+be connected through a segment of some other kind of bus; but its
+registers will still be directly addressible.
+
+Platform devices are given a name, used in driver binding, and a
+list of resources such as addresses and IRQs.
+
+struct platform_device {
+ const char *name;
+ u32 id;
+ struct device dev;
+ u32 num_resources;
+ struct resource *resource;
+};
Platform drivers
~~~~~~~~~~~~~~~~
-Drivers for platform devices are typically very simple and
-unstructured. Either the device was present at a particular I/O port
-and the driver was loaded, or it was not. There was no possibility
-of hotplugging or alternative discovery besides probing at a specific
-I/O address and expecting a specific response.
+Platform drivers follow the standard driver model convention, where
+discovery/enumeration is handled outside the drivers, and drivers
+provide probe() and remove() methods. They support power management
+and shutdown notifications using the standard conventions.
+
+struct platform_driver {
+ int (*probe)(struct platform_device *);

+Note that probe() should general verify that the specified device hardware

+can use device resources, including clocks, and device platform_data.
+
+Platform drivers register themselves the normal way:
+
+ int platform_driver_register(struct platform_driver *drv);
+
+Or, in common situations where the device is known not to be hot-pluggable,
+the probe() routine can live in an init section to reduce the driver's
+runtime memory footprint:
+
+ int platform_driver_probe(struct platform_driver *drv,
+ int (*probe)(struct platform_device *))
-Other Architectures, Modern Firmware, and new Platforms
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-These devices are not always at the legacy I/O ports. This is true on
-other architectures and on some modern architectures. In most cases,
-the drivers are modified to discover the devices at other well-known
-ports for the given platform. However, the firmware in these systems
-does usually know where exactly these devices reside, and in some
-cases, it's the only way of discovering them.
+Device Enumeration
+~~~~~~~~~~~~~~~~~~
+As a rule, platform specific (and often board-specific) setup code wil
+register platform devices:
+
+ int platform_device_register(struct platform_device *pdev);
+
+ int platform_add_devices(struct platform_device **pdevs, int ndev);
+
+The general rule is to register only those devices that actually exist,
+but in some cases extra devices might be registered. For example, a kernel
+might be configured to work with an external network adapter that might not
+be populated on all boards, or likewise to work with an integrated controller
+that some boards might not hook up to any peripherals.
+
+In some cases, boot firmware will export tables describing the devices
+that are populated on a given board. Without such tables, often the
+only way for system setup code to set up the correct devices is to build
+a kernel for a specific target board. Such board-specific kernels are
+common with embedded and custom systems development.
+
+In many cases, the memory and IRQ resources associated with the platform
+device are not enough to let the device's driver work. Board setup code
+will often provide additional information using the device's platform_data
+field to hold additional information.
+
+Embedded systems frequently need one or more clocks for platform devices,
+which are normally kept off until they're actively needed (to save power).
+System setup also associates those clocks with the device, so that that
+calls to clk_get(&pdev->dev, clock_name) return them as needed.
-The Platform Bus
-~~~~~~~~~~~~~~~~
-A platform bus has been created to deal with these issues. First and
-foremost, it groups all the legacy devices under a common bus, and
-gives them a common parent if they don't already have one.
+Device Naming and Driver Binding
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The platform_device.dev.bus_id is the canonical name for the devices.
+It's built from two components:
-But, besides the organizational benefits, the platform bus can also
-accommodate firmware-based enumeration.
+ * platform_device.name ... which is also used to for driver matching.
+ * platform_device.id ... the device instance number, or else "-1"
+ to indicate there's only one.
-Device Discovery
-~~~~~~~~~~~~~~~~
-The platform bus has no concept of probing for devices. Devices
-discovery is left up to either the legacy drivers or the
-firmware. These entities are expected to notify the platform of
-devices that it discovers via the bus's add() callback:
+These are catenated, so name/id "serial"/0 indicates bus_id "serial.0", and
+"serial/3" indicates bus_id "serial.3"; both would use the platform_driver
+named "serial". While "my_rtc"/-1 would be bus_id "my_rtc" (no instance id)
+and use the platform_driver called "my_rtc".
- platform_bus.add(parent,bus_id).
+Driver binding is performed automatically by the driver core, invoking
+driver probe() after finding a match between device and driver. If the
+probe() succeeds, the driver and device are bound as usual. There are
+three different ways to find such a match:
+ - Whenever a device is registered, the drivers for that bus are
+ checked for matches. Platform devices should be registered very
+ early during system boot.
-Bus IDs
-~~~~~~~
-Bus IDs are the canonical names for the devices. There is no globally
-standard addressing mechanism for legacy devices. In the IA-32 world,
-we have Pnp IDs to use, as well as the legacy I/O ports. However,
-neither tell what the device really is or have any meaning on other
-platforms.
+ - When a driver is registered using platform_driver_register(), all
+ unbound devices on that bus are checked for matches. Drivers
+ usually register later during booting, or by module loading.
-Since both PnP IDs and the legacy I/O ports (and other standard I/O
-ports for specific devices) have a 1:1 mapping, we map the
-platform-specific name or identifier to a generic name (at least
-within the scope of the kernel).
-
-For example, a serial driver might find a device at I/O 0x3f8. The
-ACPI firmware might also discover a device with PnP ID (_HID)
-PNP0501. Both correspond to the same device and should be mapped to the
-canonical name 'serial'.
-
-The bus_id field should be a concatenation of the canonical name and
-the instance of that type of device. For example, the device at I/O
-port 0x3f8 should have a bus_id of "serial0". This places the
-responsibility of enumerating devices of a particular type up to the
-discovery mechanism. But, they are the entity that should know best
-(as opposed to the platform bus driver).
-
-
-Drivers
-~~~~~~~
-Drivers for platform devices should have a name that is the same as
-the canonical name of the devices they support. This allows the
-platform bus driver to do simple matching with the basic data
-structures to determine if a driver supports a certain device.
-
-For example, a legacy serial driver should have a name of 'serial' and
-register itself with the platform bus.
-
-
-Driver Binding
-~~~~~~~~~~~~~~
-Legacy drivers assume they are bound to the device once they start up
-and probe an I/O port. Divorcing them from this will be a difficult
-process. However, that shouldn't prevent us from implementing
-firmware-based enumeration.
-
-The firmware should notify the platform bus about devices before the
-legacy drivers have had a chance to load. Once the drivers are loaded,
-they driver model core will attempt to bind the driver to any
-previously-discovered devices. Once that has happened, it will be free
-to discover any other devices it pleases.
+ - Registering a driver using platform_driver_probe() works just like
+ using platform_driver_register(), except that the the driver won't
+ be probed later if another device registers. (Which is OK, since
+ this interface is only for use with non-hotpluggable devices.)

+Fault injection capabilities infrastructure
+===========================================
+
+See also drivers/md/faulty.c and "every_nth" module option for scsi_debug.
+
+
+Available fault injection capabilities
+--------------------------------------
+
+o failslab
+
+ injects slab allocation failures. (kmalloc(), kmem_cache_alloc(), ...)
+
+o fail_page_alloc
+
+ injects page allocation failures. (alloc_pages(), get_free_pages(), ...)
+
+o fail_make_request
+
+ injects disk IO errors on devices permitted by setting
+ /sys/block/<device>/make-it-fail or
+ /sys/block/<device>/<partition>/make-it-fail. (generic_make_request())
+
+Configure fault-injection capabilities behavior
+-----------------------------------------------
+
+o debugfs entries
+
+fault-inject-debugfs kernel module provides some debugfs entries for runtime
+configuration of fault-injection capabilities.
+
+- /debug/fail*/probability:
+
+ likelihood of failure injection, in percent.
+ Format: <percent>
+
+ Note that one-failure-per-hundred is a very high error rate
+ for some testcases. Consider setting probability=100 and configure
+ /debug/fail*/interval for such testcases.
+
+- /debug/fail*/interval:
+
+ specifies the interval between failures, for calls to
+ should_fail() that pass all the other tests.
+
+ Note that if you enable this, by setting interval>1, you will
+ probably want to set probability=100.
+
+- /debug/fail*/times:
+
+ specifies how many times failures may happen at most.
+ A value of -1 means "no limit".
+
+- /debug/fail*/space:
+
+ specifies an initial resource "budget", decremented by "size"
+ on each call to should_fail(,size). Failure injection is
+ suppressed until "space" reaches zero.
+
+- /debug/fail*/verbose
+
+ Format: { 0 | 1 | 2 }
+ specifies the verbosity of the messages when failure is
+ injected. '0' means no messages; '1' will print only a single
+ log line per failure; '2' will print a call trace too -- useful
+ to debug the problems revealed by fault injection.
+
+- /debug/fail*/task-filter:
+
+ Format: { 'Y' | 'N' }
+ A value of 'N' disables filtering by process (default).
+ Any positive value limits failures to only processes indicated by
+ /proc/<pid>/make-it-fail==1.
+
+- /debug/fail*/require-start:
+- /debug/fail*/require-end:
+- /debug/fail*/reject-start:
+- /debug/fail*/reject-end:
+
+ specifies the range of virtual addresses tested during
+ stacktrace walking. Failure is injected only if some caller
+ in the walked stacktrace lies within the required range, and
+ none lies within the rejected range.
+ Default required range is [0,ULONG_MAX) (whole of virtual address space).
+ Default rejected range is [0,0).
+
+- /debug/fail*/stacktrace-depth:
+
+ specifies the maximum stacktrace depth walked during search
+ for a caller within [require-start,require-end) OR
+ [reject-start,reject-end).
+
+- /debug/fail_page_alloc/ignore-gfp-highmem:
+
+ Format: { 'Y' | 'N' }
+ default is 'N', setting it to 'Y' won't inject failures into
+ highmem/user allocations.
+
+- /debug/failslab/ignore-gfp-wait:
+- /debug/fail_page_alloc/ignore-gfp-wait:
+
+ Format: { 'Y' | 'N' }
+ default is 'N', setting it to 'Y' will inject failures
+ only into non-sleep allocations (GFP_ATOMIC allocations).
+
+o Boot option
+
+In order to inject faults while debugfs is not available (early boot time),
+use the boot option:
+
+ failslab=
+ fail_page_alloc=
+ fail_make_request=<interval>,<probability>,<space>,<times>
+
+How to add new fault injection capability
+-----------------------------------------
+
+o #include <linux/fault-inject.h>
+
+o define the fault attributes
+
+ DECLARE_FAULT_INJECTION(name);
+
+ Please see the definition of struct fault_attr in fault-inject.h
+ for details.
+
+o provide a way to configure fault attributes
+
+- boot option
+
+ If you need to enable the fault injection capability from boot time, you can
+ provide boot option to configure it. There is a helper function for it:
+
+ setup_fault_attr(attr, str);
+
+- debugfs entries
+
+ failslab, fail_page_alloc, and fail_make_request use this way.
+ Helper functions:
+
+ init_fault_attr_entries(entries, attr, name);
+ void cleanup_fault_attr_entries(entries);
+
+- module parameters
+
+ If the scope of the fault injection capability is limited to a
+ single kernel module, it is better to provide module parameters to
+ configure the fault attributes.
+
+o add a hook to insert failures
+
+ Upon should_fail() returning true, client code should inject a failure.
+
+ should_fail(attr, size);
+

-
-A minus 1. Ftape documentation
-==============================
-
-Unluckily, the ftape-HOWTO is out of date. This really needs to be
-changed. Up to date documentation as well as recent development
-versions of ftape and useful links to related topics can be found at
-the ftape home page at
-
-http://ftape.dot-heine.de/
-
-*******************************************************************************
-
-A. Changes
-==========
-
-1. Goal
- ~~~~
- The goal of all that incompatibilities was to give ftape an interface
- that resembles the interface provided by SCSI tape drives as close
- as possible. Thus any Unix backup program that is known to work
- with SCSI tape drives should also work.
-
- The concept of a fixed block size for read/write transfers is
- rather unrelated to this SCSI tape compatibility at the file system
- interface level. It developed out of a feature of zftape, a
- block wise user transparent on-the-fly compression. That compression
- support will not be dropped in future releases for compatibility
- reasons with previous releases of zftape.
-
-2. I/O Block Size
- ~~~~~~~~~~~~~~
- The block size defaults to 10k which is the default block size of
- GNU tar.
-
- The block size can be tuned either during kernel configuration or
- at runtime with the MTIOCTOP ioctl using the MTSETBLK operation
- (i.e. do "mt -f /dev/qft0" setblk #BLKSZ). A block size of 0
- switches to variable block size mode i.e. "mt setblk 0" switches
- off the block size restriction. However, this disables zftape's
- built in on-the-fly compression which doesn't work with variable
- block size mode.
-
- The BLKSZ parameter must be given as a byte count and must be a
- multiple of 32k or 0, i.e. use "mt setblk 32768" to switch to a
- block size of 32k.
-
- The typical symptom of a block size mismatch is an "invalid
- argument" error message.
-
-3. Write Access when not at EOD (End Of Data) or BOT (Begin Of Tape)
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- zftape (the file system interface of ftape-3.x) denies write access
- to the tape cartridge when it isn't positioned either at BOT or
- EOD.
-
-4. Formatting
- ~~~~~~~~~~
- ftape DOES support formatting of floppy tape cartridges. You need the
- `ftformat' program that is shipped with the modules version of ftape.
- Please get the latest version of ftape from
-
- ftp://sunsite.unc.edu/pub/Linux/kernel/tapes
-
- or from the ftape home page at
-
- http://ftape.dot-heine.de/
-
- `ftformat' is contained in the `./contrib/' subdirectory of that
- separate ftape package.
-
-5. Interchanging cartridges with other operating systems
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
- The internal emulation of Unix tape device file marks has changed
- completely. ftape now uses the volume table segment as specified
- by the QIC-40/80/3010/3020/113 standards to emulate file marks. As
- a consequence there is limited support to interchange cartridges
- with other operating systems.
-
- To be more precise: ftape will detect volumes written by other OS's
- programs and other OS's programs will detect volumes written by
- ftape.
-
- However, it isn't possible to extract the data dumped to the tape
- by some MSDOS program with ftape. This exceeds the scope of a
- kernel device driver. If you need such functionality, then go ahead
- and write a user space utility that is able to do that. ftape already
- provides all kernel level support necessary to do that.
-
-*******************************************************************************
-
-B. Debugging Output
- ================
-
-1. Introduction
- ~~~~~~~~~~~~
- The ftape driver can be very noisy in that is can print lots of
- debugging messages to the kernel log files and the system console.
- While this is useful for debugging it might be annoying during
- normal use and enlarges the size of the driver by several kilobytes.
-
- To reduce the size of the driver you can trim the maximal amount of
- debugging information available during kernel configuration. Please
- refer to the kernel configuration script and its on-line help
- functionality.
-
- The amount of debugging output maps to the "tracing" boot time
- option and the "ft_tracing" modules option as follows:
-
- 0 bugs
- 1 + errors (with call-stack dump)
- 2 + warnings
- 3 + information
- 4 + more information
- 5 + program flow
- 6 + fdc/dma info
- 7 + data flow
- 8 + everything else
-
-2. Tuning the debugging output
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~
- To reduce the amount of debugging output printed to the system
- console you can
-
- i) trim the debugging output at run-time with
-
- mt -f /dev/nqft0 setdensity #DBGLVL
-
- where "#DBGLVL" is a number between 0 and 9
-
- ii) trim the debugging output at module load time with
-
- modprobe ftape ft_tracing=#DBGLVL
-
- Of course, this applies only if you have configured ftape to be
- compiled as a module.
-
- iii) trim the debugging output during system boot time. Add the
- following to the kernel command line:
-
- ftape=#DBGLVL,tracing
-
- Please refer also to the next section if you don't know how to
- set boot time parameters.
-
-*******************************************************************************
-
-C. Boot and load time configuration
- ================================
-
-1. Setting boot time parameters
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Assuming that you use lilo, the LI)nux LO)ader, boot time kernel
- parameters can be set by adding a line
-
- append some_kernel_boot_time_parameter
-
- to `/etc/lilo.conf' or at real boot time by typing in the options
- at the prompt provided by LILO. I can't give you advice on how to
- specify those parameters with other loaders as I don't use them.
-
- For ftape, each "some_kernel_boot_time_parameter" looks like
- "ftape=value,option". As an example, the debugging output can be
- increased with
-
- ftape=4,tracing
-
- NOTE: the value precedes the option name.
-
-2. Module load time parameters
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Module parameters can be specified either directly when invoking
- the program 'modprobe' at the shell prompt:
-
- modprobe ftape ft_tracing=4
-
- or by editing the file `/etc/modprobe.conf' in which case they take
- effect each time when the module is loaded with `modprobe' (please
- refer to the respective manual pages). Thus, you should add a line
-
- options ftape ft_tracing=4
-
- to `/etc/modprobe.conf` if you intend to increase the debugging
- output of the driver.
-
-
-3. Ftape boot- and load time options
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
- i. Controlling the amount of debugging output
- DBGLVL has to be replaced by a number between 0 and 8.
-
- module | kernel command line
- -----------------------|----------------------
- ft_tracing=DBGLVL | ftape=DBGLVL,tracing
-
- ii. Hardware setup
- BASE is the base address of your floppy disk controller,
- IRQ and DMA give its interrupt and DMA channel, respectively.
- BOOL is an integer, "0" means "no"; any other value means
- "yes". You don't need to specify anything if connecting your tape
- drive to the standard floppy disk controller. All of these
- values have reasonable defaults. The defaults can be modified
- during kernel configuration, i.e. while running "make config",
- "make menuconfig" or "make xconfig" in the top level directory
- of the Linux kernel source tree. Please refer also to the on
- line documentation provided during that kernel configuration
- process.
-
- ft_probe_fc10 is set to a non-zero value if you wish for ftape to
- probe for a Colorado FC-10 or FC-20 controller.
-
- ft_mach2 is set to a non-zero value if you wish for ftape to probe
- for a Mountain MACH-2 controller.
-
- module | kernel command line
- -----------------------|----------------------
- ft_fdc_base=BASE | ftape=BASE,ioport
- ft_fdc_irq=IRQ | ftape=IRQ,irq
- ft_fdc_dma=DMA | ftape=DMA,dma
- ft_probe_fc10=BOOL | ftape=BOOL,fc10
- ft_mach2=BOOL | ftape=BOOL,mach2
- ft_fdc_threshold=THR | ftape=THR,threshold
- ft_fdc_rate_limit=RATE | ftape=RATE,datarate
-
-4. Example kernel parameter setting
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- To configure ftape to probe for a Colorado FC-10/FC-20 controller
- and to increase the amount of debugging output a little bit, add
- the following line to `/etc/lilo.conf':
-
- append ftape=1,fc10 ftape=4,tracing
-
-5. Example module parameter setting
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- To do the same, but with ftape compiled as a loadable kernel
- module, add the following line to `/etc/modprobe.conf':
-
- options ftape ft_probe_fc10=1 ft_tracing=4
-

+-------------------
+When using a known dance pad, jstest will report 6 axes and 14 buttons.
+
+For dance style pads (like the redoctane pad) several changes
+have been made. The old driver would map the d-pad to axes, resulting
+in the driver being unable to report when the user was pressing both

+Known dance pads automatically map the d-pad to buttons and will work

+ http://linux-net.osdl.org/index.php/TODO#DCCP
Socket options
==============
-DCCP_SOCKOPT_PACKET_SIZE is used for CCID3 to set default packet size for
-calculations.
-
DCCP_SOCKOPT_SERVICE sets the service. The specification mandates use of
service codes (RFC 4340, sec. 8.1.2); if this socket option is not set,
the socket will fall back to 0 (which means that no meaningful service code
is present). Connecting sockets set at most one service option; for
listening sockets, multiple service codes can be specified.
+DCCP_SOCKOPT_SEND_CSCOV and DCCP_SOCKOPT_RECV_CSCOV are used for setting the
+partial checksum coverage (RFC 4340, sec. 9.2). The default is that checksums
+always cover the entire packet and that only fully covered application data is
+accepted by the receiver. Hence, when using this feature on the sender, it must
+be enabled at the receiver, too with suitable choice of CsCov.
+
+DCCP_SOCKOPT_SEND_CSCOV sets the sender checksum coverage. Values in the
+ range 0..15 are acceptable. The default setting is 0 (full coverage),
+ values between 1..15 indicate partial coverage.
+DCCP_SOCKOPT_SEND_CSCOV is for the receiver and has a different meaning: it
+ sets a threshold, where again values 0..15 are acceptable. The default
+ of 0 means that all packets with a partial coverage will be discarded.
+ Values in the range 1..15 indicate that packets with minimally such a
+ coverage value are also acceptable. The higher the number, the more
+ restrictive this setting (see [RFC 4340, sec. 9.2.1]).
+
+Sysctl variables
+================
+Several DCCP default parameters can be managed by the following sysctls
+(sysctl net.dccp.default or /proc/sys/net/dccp/default):
+
+request_retries
+ The number of active connection initiation retries (the number of
+ Requests minus one) before timing out. In addition, it also governs
+ the behaviour of the other, passive side: this variable also sets
+ the number of times DCCP repeats sending a Response when the initial
+ handshake does not progress from RESPOND to OPEN (i.e. when no Ack
+ is received after the initial Request). This value should be greater
+ than 0, suggested is less than 10. Analogue of tcp_syn_retries.
+
+retries1
+ How often a DCCP Response is retransmitted until the listening DCCP
+ side considers its connecting peer dead. Analogue of tcp_retries1.
+
+retries2
+ The number of times a general DCCP packet is retransmitted. This has
+ importance for retransmitted acknowledgments and feature negotiation,
+ data packets are never retransmitted. Analogue of tcp_retries2.
+
+send_ndp = 1
+ Whether or not to send NDP count options (sec. 7.7.2).
+
+send_ackvec = 1
+ Whether or not to send Ack Vector options (sec. 11.5).
+
+ack_ratio = 2
+ The default Ack Ratio (sec. 11.3) to use.

Notes
=====
-SELinux does not yet have support for DCCP. You will need to turn it off or
-else you will get EACCES.
-
-DCCP does not travel through NAT successfully at present. This is because
-the checksum covers the psuedo-header as per TCP and UDP. It should be
-relatively trivial to add Linux NAT support for DCCP.

InterruptThrottleRate

+Default Value: 3
-This value represents the maximum number of interrupts per second the
-controller generates. InterruptThrottleRate is another setting used in
-interrupt moderation. Dynamic mode uses a heuristic algorithm to adjust
-InterruptThrottleRate based on the current traffic load.
+The driver can limit the amount of interrupts per second that the adapter
+will generate for incoming packets. It does this by writing a value to the
+adapter that is based on the maximum amount of interrupts that the adapter
+will generate per second.
+
+Setting InterruptThrottleRate to a value greater or equal to 100
+will program the adapter to send out a maximum of that many interrupts
+per second, even if more packets have come in. This reduces interrupt
+load on the system and can lower CPU utilization under heavy load,
+but will increase latency as packets are not processed as quickly.
+
+The default behaviour of the driver previously assumed a static
+InterruptThrottleRate value of 8000, providing a good fallback value for
+all traffic types,but lacking in small packet performance and latency.
+The hardware can handle many more small packets per second however, and
+for this reason an adaptive interrupt moderation algorithm was implemented.
+
+Since 7.3.x, the driver has two adaptive modes (setting 1 or 3) in which
+it dynamically adjusts the InterruptThrottleRate value based on the traffic
+that it receives. After determining the type of incoming traffic in the last
+timeframe, it will adjust the InterruptThrottleRate to an appropriate value
+for that traffic.
+
+The algorithm classifies the incoming traffic every interval into
+classes. Once the class is determined, the InterruptThrottleRate value is
+adjusted to suit that traffic type the best. There are three classes defined:
+"Bulk traffic", for large amounts of packets of normal size; "Low latency",
+for small amounts of traffic and/or a significant percentage of small
+packets; and "Lowest latency", for almost completely small packets or
+minimal traffic.
+
+In dynamic conservative mode, the InterruptThrottleRate value is set to 4000
+for traffic that falls in class "Bulk traffic". If traffic falls in the "Low
+latency" or "Lowest latency" class, the InterruptThrottleRate is increased
+stepwise to 20000. This default mode is suitable for most applications.
+
+For situations where low latency is vital such as cluster or
+grid computing, the algorithm can reduce latency even more when
+InterruptThrottleRate is set to mode 1. In this mode, which operates
+the same as mode 3, the InterruptThrottleRate will be increased stepwise to
+70000 for traffic in class "Lowest latency".
+
+Setting InterruptThrottleRate to 0 turns off any interrupt moderation
+and may improve small packet latency, but is generally not suitable
+for bulk throughput traffic.
NOTE: InterruptThrottleRate takes precedence over the TxAbsIntDelay and
- RxAbsIntDelay parameters. In other words, minimizing the receive
+ RxAbsIntDelay parameters. In other words, minimizing the receive
and/or transmit absolute delays does not force the controller to
generate more interrupts than what the Interrupt Throttle Rate
allows.

+ ===========================================================================
+ The UDP-Lite protocol (RFC 3828)
+ ===========================================================================
+
+
+ UDP-Lite is a Standards-Track IETF transport protocol whose characteristic
+ is a variable-length checksum. This has advantages for transport of multimedia
+ (video, VoIP) over wireless networks, as partly damaged packets can still be
+ fed into the codec instead of being discarded due to a failed checksum test.
+
+ This file briefly describes the existing kernel support and the socket API.
+ For in-depth information, you can consult:
+
+ o The UDP-Lite Homepage: http://www.erg.abdn.ac.uk/users/gerrit/udp-lite/
+ Fom here you can also download some example application source code.
+
+ o The UDP-Lite HOWTO on
+ http://www.erg.abdn.ac.uk/users/gerrit/udp-lite/files/UDP-Lite-HOWTO.txt
+
+ o The Wireshark UDP-Lite WiKi (with capture files):
+ http://wiki.wireshark.org/Lightweight_User_Datagram_Protocol
+
+ o The Protocol Spec, RFC 3828, http://www.ietf.org/rfc/rfc3828.txt
+
+
+ I) APPLICATIONS
+
+ Several applications have been ported successfully to UDP-Lite. Ethereal
+ (now called wireshark) has UDP-Litev4/v6 support by default. The tarball on
+
+ http://www.erg.abdn.ac.uk/users/gerrit/udp-lite/files/udplite_linux.tar.gz
+
+ has source code for several v4/v6 client-server and network testing examples.
+
+ Porting applications to UDP-Lite is straightforward: only socket level and
+ IPPROTO need to be changed; senders additionally set the checksum coverage
+ length (default = header length = 8). Details are in the next section.
+
+
+ II) PROGRAMMING API
+
+ UDP-Lite provides a connectionless, unreliable datagram service and hence
+ uses the same socket type as UDP. In fact, porting from UDP to UDP-Lite is
+ very easy: simply add `IPPROTO_UDPLITE' as the last argument of the socket(2)
+ call so that the statement looks like:
+
+ s = socket(PF_INET, SOCK_DGRAM, IPPROTO_UDPLITE);
+
+ or, respectively,
+
+ s = socket(PF_INET6, SOCK_DGRAM, IPPROTO_UDPLITE);
+
+ With just the above change you are able to run UDP-Lite services or connect
+ to UDP-Lite servers. The kernel will assume that you are not interested in
+ using partial checksum coverage and so emulate UDP mode (full coverage).
+
+ To make use of the partial checksum coverage facilities requires setting a
+ single socket option, which takes an integer specifying the coverage length:
+
+ * Sender checksum coverage: UDPLITE_SEND_CSCOV
+
+ For example,
+
+ int val = 20;
+ setsockopt(s, SOL_UDPLITE, UDPLITE_SEND_CSCOV, &val, sizeof(int));
+
+ sets the checksum coverage length to 20 bytes (12b data + 8b header).
+ Of each packet only the first 20 bytes (plus the pseudo-header) will be
+ checksummed. This is useful for RTP applications which have a 12-byte
+ base header.
+
+
+ * Receiver checksum coverage: UDPLITE_RECV_CSCOV
+
+ This option is the receiver-side analogue. It is truly optional, i.e. not
+ required to enable traffic with partial checksum coverage. Its function is
+ that of a traffic filter: when enabled, it instructs the kernel to drop
+ all packets which have a coverage _less_ than this value. For example, if
+ RTP and UDP headers are to be protected, a receiver can enforce that only
+ packets with a minimum coverage of 20 are admitted:
+
+ int min = 20;
+ setsockopt(s, SOL_UDPLITE, UDPLITE_RECV_CSCOV, &min, sizeof(int));
+
+ The calls to getsockopt(2) are analogous. Being an extension and not a stand-
+ alone protocol, all socket options known from UDP can be used in exactly the
+ same manner as before, e.g. UDP_CORK or UDP_ENCAP.
+
+ A detailed discussion of UDP-Lite checksum coverage options is in section IV.
+
+
+ III) HEADER FILES
+
+ The socket API requires support through header files in /usr/include:
+
+ * /usr/include/netinet/in.h
+ to define IPPROTO_UDPLITE
+
+ * /usr/include/netinet/udplite.h
+ for UDP-Lite header fields and protocol constants
+
+ For testing purposes, the following can serve as a `mini' header file:
+
+ #define IPPROTO_UDPLITE 136
+ #define SOL_UDPLITE 136
+ #define UDPLITE_SEND_CSCOV 10
+ #define UDPLITE_RECV_CSCOV 11
+
+ Ready-made header files for various distros are in the UDP-Lite tarball.
+
+
+ IV) KERNEL BEHAVIOUR WITH REGARD TO THE VARIOUS SOCKET OPTIONS
+
+ To enable debugging messages, the log level need to be set to 8, as most
+ messages use the KERN_DEBUG level (7).
+
+ 1) Sender Socket Options
+
+ If the sender specifies a value of 0 as coverage length, the module
+ assumes full coverage, transmits a packet with coverage length of 0
+ and according checksum. If the sender specifies a coverage < 8 and
+ different from 0, the kernel assumes 8 as default value. Finally,
+ if the specified coverage length exceeds the packet length, the packet
+ length is used instead as coverage length.
+
+ 2) Receiver Socket Options
+
+ The receiver specifies the minimum value of the coverage length it
+ is willing to accept. A value of 0 here indicates that the receiver
+ always wants the whole of the packet covered. In this case, all
+ partially covered packets are dropped and an error is logged.
+
+ It is not possible to specify illegal values (<0 and <8); in these
+ cases the default of 8 is assumed.
+
+ All packets arriving with a coverage value less than the specified
+ threshold are discarded, these events are also logged.
+
+ 3) Disabling the Checksum Computation
+
+ On both sender and receiver, checksumming will always be performed
+ and can not be disabled using SO_NO_CHECK. Thus
+
+ setsockopt(sockfd, SOL_SOCKET, SO_NO_CHECK, ... );
+
+ will always will be ignored, while the value of
+
+ getsockopt(sockfd, SOL_SOCKET, SO_NO_CHECK, &value, ...);
+
+ is meaningless (as in TCP). Packets with a zero checksum field are
+ illegal (cf. RFC 3828, sec. 3.1) will be silently discarded.
+
+ 4) Fragmentation
+
+ The checksum computation respects both buffersize and MTU. The size
+ of UDP-Lite packets is determined by the size of the send buffer. The
+ minimum size of the send buffer is 2048 (defined as SOCK_MIN_SNDBUF
+ in include/net/sock.h), the default value is configurable as
+ net.core.wmem_default or via setting the SO_SNDBUF socket(7)
+ option. The maximum upper bound for the send buffer is determined
+ by net.core.wmem_max.
+
+ Given a payload size larger than the send buffer size, UDP-Lite will
+ split the payload into several individual packets, filling up the
+ send buffer size in each case.
+
+ The precise value also depends on the interface MTU. The interface MTU,
+ in turn, may trigger IP fragmentation. In this case, the generated
+ UDP-Lite packet is split into several IP packets, of which only the
+ first one contains the L4 header.
+
+ The send buffer size has implications on the checksum coverage length.
+ Consider the following example:
+
+ Payload: 1536 bytes Send Buffer: 1024 bytes
+ MTU: 1500 bytes Coverage Length: 856 bytes
+
+ UDP-Lite will ship the 1536 bytes in two separate packets:
+
+ Packet 1: 1024 payload + 8 byte header + 20 byte IP header = 1052 bytes
+ Packet 2: 512 payload + 8 byte header + 20 byte IP header = 540 bytes
+
+ The coverage packet covers the UDP-Lite header and 848 bytes of the
+ payload in the first packet, the second packet is fully covered. Note
+ that for the second packet, the coverage length exceeds the packet
+ length. The kernel always re-adjusts the coverage length to the packet
+ length in such cases.
+
+ As an example of what happens when one UDP-Lite packet is split into
+ several tiny fragments, consider the following example.
+
+ Payload: 1024 bytes Send buffer size: 1024 bytes
+ MTU: 300 bytes Coverage length: 575 bytes
+
+ +-+-----------+--------------+--------------+--------------+
+ |8| 272 | 280 | 280 | 280 |
+ +-+-----------+--------------+--------------+--------------+
+ 280 560 840 1032
+ ^
+ *****checksum coverage*************
+
+ The UDP-Lite module generates one 1032 byte packet (1024 + 8 byte
+ header). According to the interface MTU, these are split into 4 IP
+ packets (280 byte IP payload + 20 byte IP header). The kernel module
+ sums the contents of the entire first two packets, plus 15 bytes of
+ the last packet before releasing the fragments to the IP module.
+
+ To see the analogous case for IPv6 fragmentation, consider a link
+ MTU of 1280 bytes and a write buffer of 3356 bytes. If the checksum
+ coverage is less than 1232 bytes (MTU minus IPv6/fragment header
+ lengths), only the first fragment needs to be considered. When using
+ larger checksum coverage lengths, each eligible fragment needs to be
+ checksummed. Suppose we have a checksum coverage of 3062. The buffer
+ of 3356 bytes will be split into the following fragments:
+
+ Fragment 1: 1280 bytes carrying 1232 bytes of UDP-Lite data
+ Fragment 2: 1280 bytes carrying 1232 bytes of UDP-Lite data
+ Fragment 3: 948 bytes carrying 900 bytes of UDP-Lite data
+
+ The first two fragments have to be checksummed in full, of the last
+ fragment only 598 (= 3062 - 2*1232) bytes are checksummed.
+
+ While it is important that such cases are dealt with correctly, they
+ are (annoyingly) rare: UDP-Lite is designed for optimising multimedia
+ performance over wireless (or generally noisy) links and thus smaller
+ coverage lenghts are likely to be expected.
+
+
+ V) UDP-LITE RUNTIME STATISTICS AND THEIR MEANING
+
+ Exceptional and error conditions are logged to syslog at the KERN_DEBUG
+ level. Live statistics about UDP-Lite are available in /proc/net/snmp
+ and can (with newer versions of netstat) be viewed using
+
+ netstat -svu
+
+ This displays UDP-Lite statistics variables, whose meaning is as follows.
+
+ InDatagrams: Total number of received datagrams.
+
+ NoPorts: Number of packets received to an unknown port.
+ These cases are counted separately (not as InErrors).
+
+ InErrors: Number of erroneous UDP-Lite packets. Errors include:
+ * internal socket queue receive errors
+ * packet too short (less than 8 bytes or stated
+ coverage length exceeds received length)
+ * xfrm4_policy_check() returned with error
+ * application has specified larger min. coverage
+ length than that of incoming packet
+ * checksum coverage violated
+ * bad checksum
+
+ OutDatagrams: Total number of sent datagrams.
+
+ These statistics derive from the UDP MIB (RFC 2013).
+
+
+ VI) IPTABLES
+
+ There is packet match support for UDP-Lite as well as support for the LOG target.
+ If you copy and paste the following line into /etc/protcols,
+
+ udplite 136 UDP-Lite # UDP-Lite [RFC 3828]
+
+ then
+ iptables -A INPUT -p udplite -j LOG
+
+ will produce logging output to syslog. Dropping and rejecting packets also works.

+ How to get s2ram working
+ ~~~~~~~~~~~~~~~~~~~~~~~~
+ 2006 Linus Torvalds
+ 2006 Pavel Machek
+
+1) Check suspend.sf.net, program s2ram there has long whitelist of
+ "known ok" machines, along with tricks to use on each one.
+
+2) If that does not help, try reading tricks.txt and
+ video.txt. Perhaps problem is as simple as broken module, and
+ simple module unload can fix it.
+
+3) You can use Linus' TRACE_RESUME infrastructure, described below.
+
+ Using TRACE_RESUME
+ ~~~~~~~~~~~~~~~~~~
+
+I've been working at making the machines I have able to STR, and almost
+always it's a driver that is buggy. Thank God for the suspend/resume
+debugging - the thing that Chuck tried to disable. That's often the _only_
+way to debug these things, and it's actually pretty powerful (but
+time-consuming - having to insert TRACE_RESUME() markers into the device
+driver that doesn't resume and recompile and reboot).
+
+Anyway, the way to debug this for people who are interested (have a
+machine that doesn't boot) is:
+
+ - enable PM_DEBUG, and PM_TRACE
+
+ - use a script like this:
+
+ #!/bin/sh
+ sync
+ echo 1 > /sys/power/pm_trace
+ echo mem > /sys/power/state
+
+ to suspend
+
+ - if it doesn't come back up (which is usually the problem), reboot by
+ holding the power button down, and look at the dmesg output for things
+ like
+
+ Magic number: 4:156:725
+ hash matches drivers/base/power/resume.c:28
+ hash matches device 0000:01:00.0
+
+ which means that the last trace event was just before trying to resume
+ device 0000:01:00.0. Then figure out what driver is controlling that
+ device (lspci and /sys/devices/pci* is your friend), and see if you can
+ fix it, disable it, or trace into its resume function.
+
+For example, the above happens to be the VGA device on my EVO, which I
+used to run with "radeonfb" (it's an ATI Radeon mobility). It turns out
+that "radeonfb" simply cannot resume that device - it tries to set the
+PLL's, and it just _hangs_. Using the regular VGA console and letting X
+resume it instead works fine.

+Using swap files with software suspend (swsusp)
+ (C) 2006 Rafael J. Wysocki <rjw@sisk.pl>
+
+The Linux kernel handles swap files almost in the same way as it handles swap
+partitions and there are only two differences between these two types of swap
+areas:
+(1) swap files need not be contiguous,
+(2) the header of a swap file is not in the first block of the partition that
+holds it. From the swsusp's point of view (1) is not a problem, because it is
+already taken care of by the swap-handling code, but (2) has to be taken into
+consideration.
+
+In principle the location of a swap file's header may be determined with the
+help of appropriate filesystem driver. Unfortunately, however, it requires the
+filesystem holding the swap file to be mounted, and if this filesystem is
+journaled, it cannot be mounted during resume from disk. For this reason to
+identify a swap file swsusp uses the name of the partition that holds the file
+and the offset from the beginning of the partition at which the swap file's
+header is located. For convenience, this offset is expressed in <PAGE_SIZE>
+units.
+
+In order to use a swap file with swsusp, you need to:
+
+1) Create the swap file and make it active, eg.
+
+# dd if=/dev/zero of=<swap_file_path> bs=1024 count=<swap_file_size_in_k>
+# mkswap <swap_file_path>
+# swapon <swap_file_path>
+
+2) Use an application that will bmap the swap file with the help of the
+FIBMAP ioctl and determine the location of the file's swap header, as the
+offset, in <PAGE_SIZE> units, from the beginning of the partition which
+holds the swap file.
+
+3) Add the following parameters to the kernel command line:
+
+resume=<swap_file_partition> resume_offset=<swap_file_offset>
+
+where <swap_file_partition> is the partition on which the swap file is located
+and <swap_file_offset> is the offset of the swap header determined by the
+application in 2) (of course, this step may be carried out automatically
+by the same application that determies the swap file's header offset using the
+FIBMAP ioctl)
+
+OR
+
+Use a userland suspend application that will set the partition and offset
+with the help of the SNAPSHOT_SET_SWAP_AREA ioctl described in
+Documentation/power/userland-swsusp.txt (this is the only method to suspend
+to a swap file allowing the resume to be initiated from an initrd or initramfs
+image).
+
+Now, swsusp will use the swap file in the same way in which it would use a swap
+partition. In particular, the swap file has to be active (ie. be present in
+/proc/swaps) so that it can be used for suspending.
+
+Note that if the swap file used for suspending is deleted and recreated,
+the location of its header need not be the same as before. Thus every time
+this happens the value of the "resume_offset=" kernel command line parameter
+has to be updated.

+MPC52xx Device Tree Bindings
+----------------------------
+
+(c) 2006 Secret Lab Technologies Ltd
+Grant Likely <grant.likely at secretlab.ca>
+
+I - Introduction
+================
+Boards supported by the arch/powerpc architecture require device tree be
+passed by the boot loader to the kernel at boot time. The device tree
+describes what devices are present on the board and how they are
+connected. The device tree can either be passed as a binary blob (as
+described in Documentation/powerpc/booting-without-of.txt), or passed
+by Open Firmare (IEEE 1275) compatible firmware using an OF compatible
+client interface API.
+
+This document specifies the requirements on the device-tree for mpc52xx
+based boards. These requirements are above and beyond the details
+specified in either the OpenFirmware spec or booting-without-of.txt
+
+All new mpc52xx-based boards are expected to match this document. In
+cases where this document is not sufficient to support a new board port,
+this document should be updated as part of adding the new board support.
+
+II - Philosophy
+===============
+The core of this document is naming convention. The whole point of
+defining this convention is to reduce or eliminate the number of
+special cases required to support a 52xx board. If all 52xx boards
+follow the same convention, then generic 52xx support code will work
+rather than coding special cases for each new board.
+
+This section tries to capture the thought process behind why the naming
+convention is what it is.
+
+1. Node names
+-------------
+There is strong convention/requirements already established for children
+of the root node. 'cpus' describes the processor cores, 'memory'
+describes memory, and 'chosen' provides boot configuration. Other nodes
+are added to describe devices attached to the processor local bus.
+Following convention already established with other system-on-chip
+processors, MPC52xx boards must have an 'soc5200' node as a child of the
+root node.
+
+The soc5200 node holds child nodes for all on chip devices. Child nodes
+are typically named after the configured function. ie. the FEC node is
+named 'ethernet', and a PSC in uart mode is named 'serial'.
+
+2. device_type property
+-----------------------
+similar to the node name convention above; the device_type reflects the
+configured function of a device. ie. 'serial' for a uart and 'spi' for
+an spi controller. However, while node names *should* reflect the
+configured function, device_type *must* match the configured function
+exactly.
+
+3. compatible property
+----------------------
+Since device_type isn't enough to match devices to drivers, there also
+needs to be a naming convention for the compatible property. Compatible
+is an list of device descriptions sorted from specific to generic. For
+the mpc52xx, the required format for each compatible value is
+<chip>-<device>[-<mode>]. At the minimum, the list shall contain two
+items; the first specifying the exact chip, and the second specifying
+mpc52xx for the chip.
+
+ie. ethernet on mpc5200b: compatible = "mpc5200b-ethernet\0mpc52xx-ethernet"
+
+The idea here is that most drivers will match to the most generic field
+in the compatible list (mpc52xx-*), but can also test the more specific
+field for enabling bug fixes or extra features.
+
+Modal devices, like PSCs, also append the configured function to the
+end of the compatible field. ie. A PSC in i2s mode would specify
+"mpc52xx-psc-i2s", not "mpc52xx-i2s". This convention is chosen to
+avoid naming conflicts with non-psc devices providing the same
+function. For example, "mpc52xx-spi" and "mpc52xx-psc-spi" describe
+the mpc5200 simple spi device and a PSC spi mode respectively.
+
+If the soc device is more generic and present on other SOCs, the
+compatible property can specify the more generic device type also.
+
+ie. mscan: compatible = "mpc5200-mscan\0mpc52xx-mscan\0fsl,mscan";
+
+At the time of writing, exact chip may be either 'mpc5200' or
+'mpc5200b'.
+
+Device drivers should always try to match as generically as possible.
+
+III - Structure
+===============
+The device tree for an mpc52xx board follows the structure defined in
+booting-without-of.txt with the following additional notes:
+
+0) the root node
+----------------
+Typical root description node; see booting-without-of
+
+1) The cpus node
+----------------
+The cpus node follows the basic layout described in booting-without-of.
+The bus-frequency property holds the XLB bus frequency
+The clock-frequency property holds the core frequency
+
+2) The memory node
+------------------
+Typical memory description node; see booting-without-of.
+
+3) The soc5200 node
+-------------------
+This node describes the on chip SOC peripherals. Every mpc52xx based
+board will have this node, and as such there is a common naming
+convention for SOC devices.
+
+Required properties:
+name type description
+---- ---- -----------
+device_type string must be "soc"
+ranges int should be <0 baseaddr baseaddr+10000>
+reg int must be <baseaddr 10000>
+
+Recommended properties:
+name type description
+---- ---- -----------
+compatible string should be "<chip>-soc\0mpc52xx-soc"
+ ie. "mpc5200b-soc\0mpc52xx-soc"
+#interrupt-cells int must be <3>. If it is not defined
+ here then it must be defined in every
+ soc device node.
+bus-frequency int IPB bus frequency in HZ. Clock rate
+ used by most of the soc devices.
+ Defining it here avoids needing it
+ added to every device node.
+
+4) soc5200 child nodes
+----------------------
+Any on chip SOC devices available to Linux must appear as soc5200 child nodes.
+
+Note: in the tables below, '*' matches all <chip> values. ie.
+*-pic would translate to "mpc5200-pic\0mpc52xx-pic"
+
+Required soc5200 child nodes:
+name device_type compatible Description
+---- ----------- ---------- -----------
+cdm@<addr> cdm *-cmd Clock Distribution
+pic@<addr> interrupt-controller *-pic need an interrupt
+ controller to boot
+bestcomm@<addr> dma-controller *-bestcomm 52xx pic also requires

+i2c@<addr> i2c *-i2c I2C controller
+usb@<addr> usb-ohci-be *-ohci,ohci-be USB controller
+xlb@<addr> xlb *-xlb XLB arbritrator
+
+IV - Extra Notes
+================
+
+1. Interrupt mapping
+--------------------
+The mpc52xx pic driver splits hardware IRQ numbers into two levels. The
+split reflects the layout of the PIC hardware itself, which groups
+interrupts into one of three groups; CRIT, MAIN or PERP. Also, the
+Bestcomm dma engine has it's own set of interrupt sources which are
+cascaded off of peripheral interrupt 0, which the driver interprets as a
+fourth group, SDMA.
+
+The interrupts property for device nodes using the mpc52xx pic consists
+of three cells; <L1 L2 level>
+
+ L1 := [CRIT=0, MAIN=1, PERP=2, SDMA=3]
+ L2 := interrupt number; directly mapped from the value in the
+ "ICTL PerStat, MainStat, CritStat Encoded Register"
+ level := [LEVEL_HIGH=0, EDGE_RISING=1, EDGE_FALLING=2, LEVEL_LOW=3]

- Real Time Clock Driver for Linux
- ================================
+ Real Time Clock (RTC) Drivers for Linux
+ =======================================
+
+When Linux developers talk about a "Real Time Clock", they usually mean
+something that tracks wall clock time and is battery backed so that it
+works even with system power off. Such clocks will normally not track
+the local time zone or daylight savings time -- unless they dual boot
+with MS-Windows -- but will instead be set to Coordinated Universal Time
+(UTC, formerly "Greenwich Mean Time").
+
+The newest non-PC hardware tends to just count seconds, like the time(2)
+system call reports, but RTCs also very commonly represent time using
+the Gregorian calendar and 24 hour time, as reported by gmtime(3).
+
+Linux has two largely-compatible userspace RTC API families you may
+need to know about:
+
+ * /dev/rtc ... is the RTC provided by PC compatible systems,
+ so it's not very portable to non-x86 systems.
+
+ * /dev/rtc0, /dev/rtc1 ... are part of a framework that's
+ supported by a wide variety of RTC chips on all systems.
+
+Programmers need to understand that the PC/AT functionality is not
+always available, and some systems can do much more. That is, the
+RTCs use the same API to make requests in both RTC frameworks (using
+different filenames of course), but the hardware may not offer the
+same functionality. For example, not every RTC is hooked up to an
+IRQ, so they can't all issue alarms; and where standard PC RTCs can
+only issue an alarm up to 24 hours in the future, other hardware may
+be able to schedule one any time in the upcoming century.
+
+
+ Old PC/AT-Compatible driver: /dev/rtc
+ --------------------------------------
All PCs (even Alpha machines) have a Real Time Clock built into them.
Usually they are built into the chipset of the computer, but some may
actually have a Motorola MC146818 (or clone) on the board. This is the
clock that keeps the date and time while your computer is turned off.
+ACPI has standardized that MC146818 functionality, and extended it in
+a few ways (enabling longer alarm periods, and wake-from-hibernate).
+That functionality is NOT exposed in the old driver.
+
However it can also be used to generate signals from a slow 2Hz to a
relatively fast 8192Hz, in increments of powers of two. These signals
are reported by interrupt number 8. (Oh! So *that* is what IRQ 8 is

+(The original /dev/rtc driver was written by Paul Gortmaker.)
+
+
+ New portable "RTC Class" drivers: /dev/rtcN
+ --------------------------------------------
+
+Because Linux supports many non-ACPI and non-PC platforms, some of which
+have more than one RTC style clock, it needed a more portable solution
+than expecting a single battery-backed MC146818 clone on every system.
+Accordingly, a new "RTC Class" framework has been defined. It offers
+three different userspace interfaces:
+
+ * /dev/rtcN ... much the same as the older /dev/rtc interface
+
+ * /sys/class/rtc/rtcN ... sysfs attributes support readonly
+ access to some RTC attributes.
+
+ * /proc/driver/rtc ... the first RTC (rtc0) may expose itself
+ using a procfs interface. More information is (currently) shown
+ here than through sysfs.
+
+The RTC Class framework supports a wide variety of RTCs, ranging from those
+integrated into embeddable system-on-chip (SOC) processors to discrete chips
+using I2C, SPI, or some other bus to communicate with the host CPU. There's
+even support for PC-style RTCs ... including the features exposed on newer PCs
+through ACPI.
+
+The new framework also removes the "one RTC per system" restriction. For
+example, maybe the low-power battery-backed RTC is a discrete I2C chip, but
+a high functionality RTC is integrated into the SOC. That system might read
+the system clock from the discrete RTC, but use the integrated one for all
+other tasks, because of its greater functionality.
+
+The ioctl() calls supported by /dev/rtc are also supported by the RTC class
+framework. However, because the chips and systems are not standardized,
+some PC/AT functionality might not be provided. And in the same way, some
+newer features -- including those enabled by ACPI -- are exposed by the
+RTC class framework, but can't be supported by the older driver.
+
+ * RTC_RD_TIME, RTC_SET_TIME ... every RTC supports at least reading
+ time, returning the result as a Gregorian calendar date and 24 hour
+ wall clock time. To be most useful, this time may also be updated.
+
+ * RTC_AIE_ON, RTC_AIE_OFF, RTC_ALM_SET, RTC_ALM_READ ... when the RTC
+ is connected to an IRQ line, it can often issue an alarm IRQ up to
+ 24 hours in the future.
+
+ * RTC_WKALM_SET, RTC_WKALM_READ ... RTCs that can issue alarms beyond
+ the next 24 hours use a slightly more powerful API, which supports
+ setting the longer alarm time and enabling its IRQ using a single
+ request (using the same model as EFI firmware).
+
+ * RTC_UIE_ON, RTC_UIE_OFF ... if the RTC offers IRQs, it probably
+ also offers update IRQs whenever the "seconds" counter changes.
+ If needed, the RTC framework can emulate this mechanism.
+
+ * RTC_PIE_ON, RTC_PIE_OFF, RTC_IRQP_SET, RTC_IRQP_READ ... another
+ feature often accessible with an IRQ line is a periodic IRQ, issued
+ at settable frequencies (usually 2^N Hz).
+
+In many cases, the RTC alarm can be a system wake event, used to force
+Linux out of a low power sleep state (or hibernation) back to a fully
+operational state. For example, a system could enter a deep power saving
+state until it's time to execute some scheduled tasks.

+"cafe_ccic" is a driver for the Marvell 88ALP01 "cafe" CMOS camera
+controller. This is the controller found in first-generation OLPC systems,
+and this driver was written with support from the OLPC project.
+
+Current status: the core driver works. It can generate data in YUV422,
+RGB565, and RGB444 formats. (Anybody looking at the code will see RGB32 as
+well, but that is a debugging aid which will be removed shortly). VGA and
+QVGA modes work; CIF is there but the colors remain funky. Only the OV7670
+sensor is known to work with this controller at this time.
+
+To try it out: either of these commands will work:
+
+ mplayer tv:// -tv driver=v4l2:width=640:height=480 -nosound
+ mplayer tv:// -tv driver=v4l2:width=640:height=480:outfmt=bgr16 -nosound
+
+The "xawtv" utility also works; gqcam does not, for unknown reasons.
+
+There are a few load-time options, most of which can be changed after
+loading via sysfs as well:
+
+ - alloc_bufs_at_load: Normally, the driver will not allocate any DMA
+ buffers until the time comes to transfer data. If this option is set,
+ then worst-case-sized buffers will be allocated at module load time.
+ This option nails down the memory for the life of the module, but
+ perhaps decreases the chances of an allocation failure later on.
+
+ - dma_buf_size: The size of DMA buffers to allocate. Note that this
+ option is only consulted for load-time allocation; when buffers are
+ allocated at run time, they will be sized appropriately for the current
+ camera settings.
+
+ - n_dma_bufs: The controller can cycle through either two or three DMA
+ buffers. Normally, the driver tries to use three buffers; on faster
+ systems, however, it will work well with only two.
+
+ - min_buffers: The minimum number of streaming I/O buffers that the driver
+ will consent to work with. Default is one, but, on slower systems,
+ better behavior with mplayer can be achieved by setting to a higher
+ value (like six).
+
+ - max_buffers: The maximum number of streaming I/O buffers; default is
+ ten. That number was carefully picked out of a hat and should not be
+ assumed to actually mean much of anything.
+
+ - flip: If this boolean parameter is set, the sensor will be instructed to
+ invert the video image. Whether it makes sense is determined by how
+ your particular camera is mounted.
+
+Work is ongoing with this driver, stay tuned.

-Driver for Trust Computer Products Framegrabber, version 0.6.1
------- --- ----- -------- -------- ------------ ------- - - -
-
-- ZORAN ------------------------------------------------------
- Author: Pauline Middelink <middelin@polyware.nl>
- Date: 18 September 1999
-Version: 0.6.1
-
-- Description ------------------------------------------------
-
-Video4Linux compatible driver for an unknown brand framegrabber
-(Sold in the Netherlands by TRUST Computer Products) and various
-other zoran zr36120 based framegrabbers.
-
-The card contains a ZR36120 Multimedia PCI Interface and a Philips
-SAA7110 Onechip Frontend videodecoder. There is also an DSP of
-which I have forgotten the number, since i will never get that thing
-to work without specs from the vendor itself.
-
-The SAA711x are capable of processing 6 different video inputs,
-CVBS1..6 and Y1+C1, Y2+C2, Y3+C3. All in 50/60Hz, NTSC, PAL or
-SECAM and delivering a YUV datastream. On my card the input
-'CVBS-0' corresponds to channel CVBS2 and 'S-Video' to Y2+C2.
-
-I have some reports of other cards working with the mentioned
-chip sets. For a list of other working cards please have a look
-at the cards named in the tvcards struct in the beginning of
-zr36120.c
-
-After some testing, I discovered that the carddesigner messed up
-on the I2C interface. The Zoran chip includes 2 lines SDA and SCL
-which (s)he connected reversely. So we have to clock on the SDA
-and r/w data on the SCL pin. Life is fun... Each cardtype now has
-a bit which signifies if you have a card with the same deficiency.
-
-Oh, for the completeness of this story I must mention that my
-card delivers the VSYNC pulse of the SAA chip to GIRQ1, not
-GIRQ0 as some other cards have. This is also incorporated in
-the driver be clearing/setting the 'useirq1' bit in the tvcard
-description.
-
-Another problems of continuous capturing data with a Zoran chip
-is something nasty inside the chip. It effectively halves the
-fps we ought to get... Here is the scenario: capturing frames
-to memory is done in the so-called snapshot mode. In this mode
-the Zoran stops after capturing a frame worth of data and wait
-till the application set GRAB bit to indicate readiness for the
-next frame. After detecting a set bit, the chip neatly waits
-till the start of a frame, captures it and it goes back to off.
-Smart ppl will notice the problem here. Its the waiting on the
-_next_ frame each time we set the GRAB bit... Oh well, 12,5 fps
-is still plenty fast for me.
--- update 28/7/1999 --
-Don't believe a word I just said... Proof is the output
-of `streamer -t 300 -r 25 -f avi15 -o /dev/null`

- syncer: done
- writer: done
-(note the /dev/null is prudent here, my system is not able to
- grab /and/ write 25 fps to a file... gifts welcome :) )
-The technical reasoning follows: The zoran completed the last
-frame, the VSYNC goes low, and GRAB is cleared. The interrupt
-routine starts to work since its VSYNC driven, and again
-activates the GRAB bit. A few ms later the VSYNC (re-)rises and
-the zoran starts to work on a new and freshly broadcasted frame....
-
-For pointers I used the specs of both chips. Below are the URLs:
- http://www.zoran.com/ftp/download/devices/pci/ZR36120/36120data.pdf
- http://www-us.semiconductor.philips.com/acrobat/datasheets/SAA_7110_A_1.pdf
-Some alternatives for the Philips SAA 7110 datasheet are:
- http://www.datasheetcatalog.com/datasheets_pdf/S/A/A/7/SAA7110.shtml
- http://www.datasheetarchive.com/search.php?search=SAA7110&sType=part
-
-The documentation has very little on absolute numbers or timings
-needed for the various modes/resolutions, but there are other
-programs you can borrow those from.
-
------- Install --------------------------------------------
-Read the file called TODO. Note its long list of limitations.
-
-Build a kernel with VIDEO4LINUX enabled. Activate the
-BT848 driver; we need this because we have need for the
-other modules (i2c and videodev) it enables.
-
-To install this software, extract it into a suitable directory.
-Examine the makefile and change anything you don't like. Type "make".
-
-After making the modules check if you have the much needed
-/dev/video devices. If not, execute the following 4 lines:
- mknod /dev/video c 81 0
- mknod /dev/video1 c 81 1
- mknod /dev/video2 c 81 2
- mknod /dev/video3 c 81 3
- mknod /dev/video4 c 81 4
-
-After making/checking the devices do:
- modprobe i2c
- modprobe videodev
- modprobe saa7110 (optional)
- modprobe saa7111 (optional)
- modprobe tuner (optional)
- insmod zoran cardtype=<n>
-
-<n> is the cardtype of the card you have. The cardnumber can
-be found in the source of zr36120. Look for tvcards. If your
-card is not there, please try if any other card gives some
-response, and mail me if you got a working tvcard addition.
-
-PS. <TVCard editors behold!)
- Don't forget to set video_input to the number of inputs
- you defined in the video_mux part of the tvcard definition.
- It's a common error to add a channel but not incrementing
- video_input and getting angry with me/v4l/linux/linus :(
-
-You are now ready to test the framegrabber with your favorite
-video4linux compatible tool
-
------- Application ----------------------------------------
-
-This device works with all Video4Linux compatible applications,
-given the limitations in the TODO file.
-
------- API ------------------------------------------------
-
-This uses the V4L interface as of kernel release 2.1.116, and in
-fact has not been tested on any lower version. There are a couple
-of minor differences due to the fact that the amount of data returned
-with each frame varies, and no doubt there are discrepancies due to my
-misunderstanding of the API. I intend to convert this driver to the
-new V4L2 API when it has stabilized more.
-
------- Current state --------------------------------------
-
-The driver is capable of overlaying a video image in screen, and
-even capable of grabbing frames. It uses the BIGPHYSAREA patch
-to allocate lots of large memory blocks when tis patch is
-found in the kernel, but it doesn't need it.
-The consequence is that, when loading the driver as a module,
-the module may tell you it's out of memory, but 'free' says
-otherwise. The reason is simple; the modules wants its memory
-contiguous, not fragmented, and after a long uptime there
-probably isn't a fragment of memory large enough...
-
-The driver uses a double buffering scheme, which should really
-be an n-way buffer, depending on the size of allocated framebuffer
-and the requested grab-size/format.
-This current version also fixes a dead-lock situation during irq
-time, which really, really froze my system... :)
-
-Good luck.
- Pauline

- * - Update Config.help entry. I got a number of emails asking
- * me to tell their senders if they could make use of this
- * piece of code... So: "SRM is something like BIOS for your
- * Alpha"
- * - Update code formatting a bit to better conform CodingStyle
- * rules.
- * - So this is v0.0.5, with no changes (except formatting)
- *
- * Wed, 22 May 2002 00:11:21 +0200
- * - Fix typo on comment (SRC -> SRM)
- * - Call this "Version 0.0.4"
- *
- * Tue, 9 Apr 2002 18:44:40 +0200
- * - Implement access by variable name and additionally
- * by number. This is done by creating two subdirectories
- * where one holds all names (like the old directory
- * did) and the other holding 256 files named like "0",
- * "1" and so on.
- * - Call this "Version 0.0.3"

- of kexec on panic the fail safe kernel needs to run at a different
- address than the panic-ed kernel. This option is used to set the load
- address for kernels used to capture crash dump on being kexec'ed
- after panic. The default value for crash dump kernels is
- 0x1000000 (16MB). This can also be set based on the "X" value as
- specified in the "crashkernel=YM@XM" command line boot parameter
- passed to the panic-ed kernel. Typically this parameter is set as
- crashkernel=64M@16M. Please take a look at
- Documentation/kdump/kdump.txt for more details about crash dumps.
+ This build a kernel image that retains relocation information
+ so it can be loaded someplace besides the default 1MB.
+ The relocations tend to the kernel binary about 10% larger,

+ This value puts the alignment restrictions on physical address
+ where kernel is loaded and run from. Kernel is compiled for an
+ address which meets above alignment restriction.
+
+ If bootloader loads the kernel at a non-aligned address and
+ CONFIG_RELOCATABLE is set, kernel will move itself to nearest
+ address aligned to above value and run from there.
+
+ If bootloader loads the kernel at a non-aligned address and
+ CONFIG_RELOCATABLE is not set, kernel will ignore the run time
+ load address and decompress itself to the address it has been
+ compiled for and run from there. The address for which kernel is
+ compiled already meets above alignment restrictions. Hence the
+ end result is that kernel runs from a physical address meeting
+ above alignment restrictions.
Don't change this unless you know what you are doing.

+ * The buffer for decompression in place is the length of the
+ * uncompressed data, plus a small amount extra to keep the algorithm safe.
+ * The compressed data is placed at the end of the buffer. The output
+ * pointer is placed at the start of the buffer and the input pointer
+ * is placed where the compressed data starts. Problems will occur
+ * when the output pointer overruns the input pointer.
+ *
+ * The output pointer can only overrun the input pointer if the input
+ * pointer is moving faster than the output pointer. A condition only
+ * triggered by data whose compressed form is larger than the uncompressed
+ * form.
+ *
+ * The worst case at the block level is a growth of the compressed data
+ * of 5 bytes per 32767 bytes.
+ *
+ * The worst case internal to a compressed block is very hard to figure.
+ * The worst case can at least be boundined by having one bit that represents
+ * 32764 bytes and then all of the rest of the bytes representing the very
+ * very last byte.
+ *
+ * All of which is enough to compute an amount of extra data that is required
+ * to be safe. To avoid problems at the block level allocating 5 extra bytes
+ * per 32767 bytes of data is sufficient. To avoind problems internal to a block
+ * adding an extra 32767 bytes (the worst case uncompressed block size) is
+ * sufficient, to ensure that in the worst case the decompressed data for
+ * block will stop the byte before the compressed data for a block begins.
+ * To avoid problems with the compressed data's meta information an extra 18
+ * bytes are needed. Leading to the formula:
+ *
+ * extra_bytes = (uncompressed_size >> 12) + 32768 + 18 + decompressor_size.
+ *
+ * Adding 8 bytes per 32K is a bit excessive but much easier to calculate.
+ * Adding 32768 instead of 32767 just makes for round numbers.
+ * Adding the decompressor_size is necessary as it musht live after all
+ * of the data as well. Last I measured the decompressor is about 14K.

+ kexec is a system call that implements the ability to shutdown your

+ you can start any kernel with it, not just Linux.
+
+ The name comes from the similiarity to the exec system call.
+
+ It is an ongoing process to be certain the hardware in a machine

+ support. As of this writing the exact hardware interface is
+ strongly in flux, so no good recommendation can be made.

- * Depending on the hardware on your board and your board design, the

- * 'nvram_as1' NULL. If your board uses address/data regs to access nvram,
- * set 'nvram_as0' to the address of the lower byte, set 'nvram_as1' to the
- * address of the upper byte (leave NULL if using mc146818), and set
- * 'nvram_data' to the address of the 8-bit data register.
- *
- * Note: Even though the documentation for the various RTC chips say that it
- * take up to a second before it starts updating once the 'R' bit is
- * cleared, they always seem to update even though we bang on it many
- * times a second. This is true, except for the Dallas Semi 1746/1747

+-=-=-= OPCODE =-=-=-
+
+OPCODE field specifies the most significant 11bit of the instruction. Some formats don't have 11bits for opcode field, and in this
+case, bit field other than op are defined as 0s. For example, opcode of fma instruction which is RRR format is defined as 0x700,
+since 0x700 -> 11'b11100000000, this means opcode is 4'b1110, and other 7bits are defined as 7'b0000000.

+
+Note that RRR instructions have the names for RC and RT reversed from
+what's in the ISA, in order to put RT in the same position it appears
+for other formats.
+
+-=-=-= DEPENDENCY =-=-=-
+
+DEPENDENCY filed consists of 5 digits. This represents which register is used as source and which register is used as target.
+The first(most significant) digit is always 0. Then it is followd by RC, RB, RA and RT digits.
+If the digit is 0, this means the corresponding register is not used in the instruction.
+If the digit is 1, this means the corresponding register is used as a source in the instruction.
+If the digit is 2, this means the corresponding register is used as a target in the instruction.
+If the digit is 3, this means the corresponding register is used as both source and target in the instruction.
+For example, fms instruction has 00113 as the DEPENDENCY field. This means RC is not used in this operation, RB and RA are
+used as sources and RT is the target.
+
+-=-=-= PIPE =-=-=-
+
+This field shows which execution pipe is used for the instruction
+
+pipe0 execution pipelines:
+ FP6 SP floating pipeline
+ FP7 integer operations executed in SP floating pipeline
+ FPD DP floating pipeline
+ FX2 FXU pipeline
+ FX3 Rotate/Shift pipeline

- * A brief note about the reasons for this API as it stands.
- *
- * For starters, the old ISA DMA API didn't work for us for a number of
- * reasons, for one, the vast majority of channels on the SH DMAC are
- * dual-address mode only, and both the new and the old DMA APIs are after the
- * concept of managing a DMA buffer, which doesn't overly fit this model very
- * well. In addition to which, the new API is largely geared at IOMMUs and
- * GARTs, and doesn't even support the channel notion very well.
- *
- * The other thing that's a marginal issue, is the sheer number of random DMA
- * engines that are present (ie, in boards like the Dreamcast), some of which
- * cascade off of the SH DMAC, and others do not. As such, there was a real
- * need for a scalable subsystem that could deal with both single and
- * dual-address mode usage, in addition to interoperating with cascaded DMACs.
- *
- * There really isn't any reason why this needs to be SH specific, though I'm
- * not aware of too many other processors (with the exception of some MIPS)
- * that have the same concept of a dual address mode, or any real desire to
- * actually make use of the DMAC even if such a subsystem were exposed
- * elsewhere.
- *
- * The idea for this was derived from the ARM port, which acted as an excellent
- * reference when trying to address these issues.
- *
- * It should also be noted that the decision to add Yet Another DMA API(tm) to
- * the kernel wasn't made easily, and was only decided upon after conferring
- * with jejb with regards to the state of the old and new APIs as they applied
- * to these circumstances. Philip Blundell was also a great help in figuring
- * out some single-address mode DMA semantics that were otherwise rather
- * confusing.

-config ZFTAPE
- tristate "Zftape, the VFS interface"
- depends on FTAPE
- ---help---
- Normally, you want to say Y or M. DON'T say N here or you
- WON'T BE ABLE TO USE YOUR FLOPPY TAPE DRIVE.
-
- The ftape module itself no longer contains the routines necessary
- to interface with the kernel VFS layer (i.e. to actually write data
- to and read data from the tape drive). Instead the file system
- interface (i.e. the hardware independent part of the driver) has
- been moved to a separate module.
-
- To compile this driver as a module, choose M here: the
- module will be called zftape.
-
- Regardless of whether you say Y or M here, an additional runtime
- loadable module called `zft-compressor' which contains code to
- support user transparent on-the-fly compression based on Ross
- William's lzrw3 algorithm will be produced. If you have enabled the
- kernel module loader (i.e. have said Y to "Kernel module loader
- support", above) then `zft-compressor' will be loaded
- automatically by zftape when needed.
-
- Despite its name, zftape does NOT use compression by default.
-
-config ZFT_DFLT_BLK_SZ
- int "Default block size"
- depends on ZFTAPE
- default "10240"
- ---help---
- If unsure leave this at its default value, i.e. 10240. Note that
- you specify only the default block size here. The block size can be
- changed at run time using the MTSETBLK tape operation with the
- MTIOCTOP ioctl (i.e. with "mt -f /dev/qft0 setblk #BLKSZ" from the
- shell command line).
-
- The probably most striking difference between zftape and previous
- versions of ftape is the fact that all data must be written or read
- in multiples of a fixed block size. The block size defaults to
- 10240 which is what GNU tar uses. The values for the block size
- should be either 1 or multiples of 1024 up to a maximum value of
- 63488 (i.e. 62 K). If you specify `1' then zftape's builtin
- compression will be disabled.
-
- Reasonable values are `10240' (GNU tar's default block size),
- `5120' (afio's default block size), `32768' (default block size some
- backup programs assume for SCSI tape drives) or `1' (no restriction
- on block size, but disables builtin compression).

- help
- Please leave this at `3' unless you REALLY know what you are doing.
- It is not necessary to change this value. Values below 3 make the
- proper use of ftape impossible, values greater than 3 are a waste of
- memory. You can change the amount of DMA memory used by ftape at
- runtime with "mt -f /dev/qft0 setdrvbuffer #NUMBUFFERS". Each buffer
- wastes 32 KB of memory. Please note that this memory cannot be
- swapped out.
-
-config FT_PROC_FS
- bool "Enable procfs status report (+2kb)"
- depends on FTAPE && PROC_FS
- ---help---
- Optional. Saying Y will result in creation of a directory
- `/proc/ftape' under the /proc file system. The files can be viewed
- with your favorite pager (i.e. use "more /proc/ftape/history" or
- "less /proc/ftape/history" or simply "cat /proc/ftape/history"). The
- file will contain some status information about the inserted
- cartridge, the kernel driver, your tape drive, the floppy disk
- controller and the error history for the most recent use of the
- kernel driver. Saying Y will enlarge the size of the ftape driver
- by approximately 2 KB.
-
- WARNING: When compiling ftape as a module (i.e. saying M to "Floppy
- tape drive") it is dangerous to use ftape's /proc file system
- interface. Accessing `/proc/ftape' while the module is unloaded will
- result in a kernel Oops. This cannot be fixed from inside ftape.

- This option controls the amount of debugging output the ftape driver
- is ABLE to produce; it does not increase or diminish the debugging
- level itself. If unsure, leave this at its default setting,
- i.e. choose "Normal".
-
- Ftape can print lots of debugging messages to the system console
- resp. kernel log files. Reducing the amount of possible debugging
- output reduces the size of the kernel module by some KB, so it might
- be a good idea to use "None" for emergency boot floppies.
-
- If you want to save memory then the following strategy is
- recommended: leave this option at its default setting "Normal" until
- you know that the driver works as expected, afterwards reconfigure
- the kernel, this time specifying "Reduced" or "None" and recompile
- and install the kernel as usual. Note that choosing "Excessive"
- debugging output does not increase the amount of debugging output
- printed to the console but only makes it possible to produce

-Some notes for ftape users with PCI motherboards:
-=================================================
-
-The problem:
-------------
-
-There have been some problem reports from people using PCI-bus based
-systems getting overrun errors.
-I wasn't able to reproduce these until I ran ftape on a Intel Plato
-(Premiere PCI II) motherboard with bios version 1.00.08AX1.
-It turned out that if GAT (Guaranteed Access Timing) is enabled (?)
-ftape gets a lot of overrun errors.
-The problem disappears when disabling GAT in the bios.
-Note that Intel removed this setting (permanently disabled) from the
-1.00.10AX1 bios !
-
-It looks like that if GAT is enabled there are often large periods
-(greater than 120 us !??) on the ISA bus that the DMA controller cannot
-service the floppy disk controller.
-I cannot imagine this being acceptable in a decent PCI implementation.
-Maybe this is a `feature' of the chipset. I can only speculate why
-Intel choose to remove the option from the latest Bios...
-
-The lesson of this all is that there may be other motherboard
-implementations having the same of similar problems.
-If you experience a lot of overrun errors during a backup to tape,
-see if there is some setting in the Bios that may influence the
-bus timing.
-
-I judge this a hardware problem and not a limitation of ftape ;-)
-My DOS backup software seems to be suffering from the same problems
-and even refuses to run at 1 Mbps !
-Ftape will reduce the data-rate from 1 Mbps to 500 Kbps if the number
-of overrun errors on a track exceeds a threshold.
-
-
-Possible solutions:
--------------------
-
-Some of the problems were solved by upgrading the (flash) bios.
-Other suggest that it has to do with the FDC being on the PCI
-bus, but that is not the case with the Intel Premiere II boards.
-[If upgrading the bios doesn't solve the problem you could try
-a floppy disk controller on the isa-bus].
-
-Here is a list of systems and recommended BIOS settings:
-
-
- Intel Premiere PCI (Revenge):
-
-Bios version 1.00.09.AF2 is reported to work.
-
-
-
- Intel Premiere PCI II (Plato):
-
-Bios version 1.00.10.AX1 and version 11 beta are ok.
-If using version 1.00.08.AX1, GAT must be disabled !
-
-
-
- ASUS PCI/I-SP3G:
-
-Preferred settings: ISA-GAT-mode : disabled
- DMA-linebuffer-mode : standard
- ISA-masterbuffer-mode : standard
-
-
- DELL Dimension XPS P90
-
-Bios version A2 is reported to be broken, while bios version A5 works.
-You can get a flash bios upgrade from http://www.dell.com
-
-
-To see if you're having the GAT problem, try making a backup
-under DOS. If it's very slow and often repositions you're
-probably having this problem.

-Hey, Emacs, we're -*-Text-*- mode!
-
-===== Release notes for ftape-3.04d 25/11/97 =====
-- The correct pre-processor statement for "else if" is "#elif" not
- "elsif".
-- Need to call zft_reset_position() when overwriting cartridges
- previously written with ftape-2.x, sftape, or ancient
- (pre-ftape-3.x) versions of zftape.
-
-===== Release notes for ftape-3.04c 16/11/97 =====
-- fdc_probe() was calling DUMPREGS with a result length of "1" which
- was just fine. Undo previous change.
-
-===== Release notes for ftape-3.04b 14/11/97 =====
-
-- patches/2.x.x/floppy.c.diff was somewhat broken, releasing i/o
- regions it never had allocated.
-- fdc_probe() was calling DUMPREGS with a result length of "1" instead
- of "10"
-- Writing deleted data marks if the first segents on track zero are
- should work now.
-- ftformat should now be able to handle those cases where the tape
- drive sets the read only status bit (QIC-40/80 cartridges with
- QIC-3010/3020 tape drives) because the header segment is damaged.
-- the MTIOCFTCMD ioctl may now be issued by the superuser ONLY.
-
-===== Release notes for ftape-3.04a 12/11/97 =====
-- Fix an "infinite loop can't be killed by signal" bug in
- ftape_get_drive_status(). Only relevant when trying to access
- buggy/misconfigured hardware
-- Try to compensate a bug in the HP Colorado T3000's firmware: it
- doesn't set the write protect bit for QIC80/QIC40 cartridges.
-
-===== Release notes for ftape-3.04 06/11/97 =====
-- If positioning with fast seeking fails fall back to a slow seek
- before giving up.
-- (nearly) no retries on "no data errors" when verifying after
- formatting. Improved tuning of the bad sector map after formatting.
-- the directory layout has changed again to allow for easier kernel
- integration
-- Module parameter "ftape_tracing" now is called "ft_tracing" because
- the "ftape_tracing" variable has the version checksum attached to it.
-- `/proc/ftape' interface for 2.0.* kernels. `/proc/ftape' no longer
- is a directory but a file that contains all the information formerly
- provided in separate files under the `/proc/ftape/' directory.
-- Most of the configuration options have been prefixed by "CONFIG_FT_"
- in preparation of the kernel inclusion. The Makefiles under
- "./ftape/" should be directly usable by the kernel.
-- The MODVERSIONS stuff is now auto-detected.
-- Broke backslashed multi line options in MCONFIG into separate lines
- using GNU-make's "+=" feature.
-- The html and dvi version of the manual is now installed under
- '/usr/doc/ftape` with 'make install`
-- New SMP define in MCONFIG. ftape works with SMP if this is defined.
-- attempt to cope with "excessive overrun errors" by gradually
- increasing FDC FIFO threshold. But this doesn't seem to have too
- much an effect.
-- New load time configuration parameter "ft_fdc_rate_limit". If you
- encounter too many overrun errors with a 2Mb controller then you
- might want to set this to 1000.
-- overrun errors on the last sector in a segment sometimes result in
- a zero DMA residue. Dunno why, but compensate for it.
-- there were still fdc_read() timeout errors. I think I have fixed it
- now, please FIXME.
-- Sometimes ftape_write() failed to re-start the tape drive when a
- segment without a good sector was reached ("wait for empty segment
- failed"). This is fixed. Especially important for > QIC-3010.
-- sftape (aka ftape-2.x) has vanished. I didn't work on it for
- ages. It is probably still possible to use the old code with
- ftape-3.04, if one really needs it (BUT RECOMPILE IT)
-- zftape no longer alters the contents of already existing volume
- table entries, which makes it possible to fill in missing fields,
- like time stamps using some user space program.
-- ./contrib/vtblc/ contains such a program.
-- new perl script ./contrib/scripts/listtape that list the contents of a
- floppy tape cartridge parsing the output of "mt volinfo" + "mt fsf"
-- the MTWEOF implementation has changed a little bit (after I had a
- look at amanda). Calling MTWEOF while the tape is still held open
- after writing something to the tape now will terminate the current
- volume, and start a new one at the current position.
-- the volume table maintained by zftape now is a doubly linked list
- that grows dynamically as needed.
-
- formatting floppy tape cartridges
- ---------------------------------
- * there is a new user space formatting program that does most of the
- dirty work in user space (auto-detect, computing the sector
- coordinates, adjusting time stamps and statistics). It has a
- simple command line interface.
- * ftape-format.o has vanished, it has been folded into the low level
- ftape.o module, and the ioctl interface into zftape.o. Most of the
- complicated stuff has been moved to user space, so there was no
- need for a separate module anymore.
- * there is a new ioctl MTIOCFTCMD that sends a bare QIC-117 command
- to the tape drive.
- * there is a new mmap() feature to map the dma buffers into user
- space to be used by the user level formatting program.
- * Formatting of yet unformatted or totally degaussed cartridges
- should be possible now. FIXME.
-
-===== Release notes for ftape-3.03b, <forgot the exact date> ====
-
-ftape-3.03b was released as a beta release only. Its main new feature
-was support of the DITTO-2GB drive. This was made possible by reverse
-engineering done by <fill in his name> after Iomega failed to support
-ftape. Although they had promised to do so (this makes me feel a bit
-sad and uncomfortable about Iomega).
-
-===== Release notes for ftape-3.03a, 22/05/97 ====
-
-- Finally fixed auto-un-loading of modules for kernels > 2.1.18
-- Add an "uninstall" target to the Makefile
-- removed the kdtime hack
-- texi2www didn't properly set the back-reference from a footnote back
- to the regular text.
-
- zftape specific
- ---------------
- * hide the old compression map volume. Taper doesn't accept the
- presence of non-Taper volumes and Taper-written volume on the same
- tape.
- * EOD (End Of Data) handling was still broken: the expected behavior
- is to return a zero byte count at the first attempt to read past
- EOD, return a zero byte count at the second attempt to read past
- EOD and THEN return -EIO.
-
- ftape-format specific
- ---------------------
- * Detection of QIC-40 cartridges in select_tape_format() was broken
- and made it impossible to format QIC-3010/3020 cartridges.
- * There are strange "TR-1 Extra" cartridges out there which weren't
- detected properly because the don't strictly conform to the
- QIC-80, Rev. N, spec.
-
-===== Release notes for ftape-3.03, 30/04/97 =====
-
-- Removed kernel integration code from the package. I plan to provide
- a package that can be integrated into the stock kernel separately
- (hopefully soon).
- As a result, a simple `make' command now will build everything.
-- ALL compile time configuration options have been moved to the file
- `MCONFIG'.
-- Quite a few `low level' changes to allow formatting of cartridges.
-- formatting is implemented as a separate module `ftape-format.o'. The
- modified `mt' program contains sample code that shows how to use it.
-- The VFS interface has been moved from the `ftape.o' module to the
- high level modules `zftape.o' resp. `sftape.o'. `ftape.o' contains
- the hardware support only.
-- A bit of /proc support for kernels > 2.1.28
-- Moved documentation to Doc subdir. INSTALL now contains some real
- installation notes.
-- `install' target in Makefile.
-
-zftape specific:
-----------------
-
-- zftape works for large cartridges now ( > 2^31 bytes)
-- MTIOCVOLINFO and MTIOCGETSIZE now return the size in KILOBYTES,
- NO LONGER in bytes.
-
-- permissions for write access to a cartridge have changed:
- * zftape now also takes the file access mode into account
- * zftape no longer allows writing in the middle of the recorded
- media. The tape has to be positioned at BOT or EOD for write
- access.
-
-- MTBSF has changed. It used to position at the beginning of the
- previous file when called with count 1. This was different from the
- expected behavior for other Un*x tape drivers (i.e. SCSI). MTBSF
- with count 1 should merely position at the beginning of the current
- volume. Fixed. As a result, `tar --verify' now produces the desired
- result: it verifies the last written volume, not the pre-last
- written volume.
-
-- The compression map has vanished --> no need for `mt erase' any
- more. Fast seeking in a compressed volume is still be possible, but
- takes slightly longer. As a side effect, you may experience an
- additional volume showing up in front of all others for old
- cartridges. This is the tape volume that holds the compression map.
-
-- The compression support for zftape has been moved to a separate
- module `zft-compressor'. DON'T forget to load it before trying to
- read back compressed volumes. The stock `zftape.o' module probes for
- the module `zft-compressor' using the kerneld message channel; you
- have to install `zft-compressor.o' in a place where modprobe can
- find it if you want to use this.
-
-- New experimental feature that tries to get the broken down GMT time
- from user space via a kernel daemon message channel. You need to
- compile and start the `kdtime' daemon contained in the contrib
- directory to use it. Needed (?) for time stamps in the header
- segments and the volume table.
-
-- variable block size mode via MTSETBLK 0
-
-- keep modules locked in memory after the block size has been changed
-
-sftape specific:
-----------------
-
-- end of tape handling should be fixed, i.e. multi volume archives
- written with `afio' can be read back now.
-
-
-===== Release notes for ftape-3.02a, 09/01/97 =====
-
-No big news:
-- call zft_init() resp. sft_init() when compiling the entire stuff
- into the kernel image.
-- fix bug in ftape-setup.c when NO_TRACE_AT_ALL was defined.
-- fix bug in sftape-eof.c/zftape-eof.c for old kernels (1.2.*)
-- add support for new module interface for recent kernels
-
-===== Release notes for ftape-3.02, 16/12/96 =====
-- Fixed the `FDC unlock command failed' bug in fdc-io.c. When the FIFO
- was already locked when ftape was loaded, ftape failed to unlock it.
-- Fixed compilation of `contrib/gnumt'. It now finds `mtio.h' even if
- ftape is NOT included into the kernel source tree.
-- fc-10.c: include <asm/io.h> for inb() and outb().
-- ftape/sftape/zftape: all global variable now have either a `ftape_',
- a `ft_', `sft_', `zft_' or `qic_' prefix to prevent name clashes
- with other parts of the kernel when including ftape into the kernel
- source tree.
-- Kerneld support has changed. `ftape' now searches for a module
- `ftape-frontend' when none of the frontend (`sftape' or `zftape') is
- loaded. Please refer to the `Installation/Loading ftape' section of
- the TeXinfo manual.
-- Add load resp. boot-time configuration of ftape. There are now
- variables ft_fdc_base, ft_fdc_dma and ft_fdc_irq corresponding to
- the former FDC_BASE etc. compile time definitions. One can also use
- the kernel command line parameters to configure the driver if it is
- compiled into the kernel. Also, the FC-10/FC-20 support is load-time
- configurable now as well as the MACH-II hack (ft_probe_fc10,
- resp. ft_mach2). Please refer to the section `Installation/Configure
- ftape' of the TeXinfo manual.
-- I removed the MODVERSIONS option from `Makefile.module'. Let me alone
- with ftape and MODVERSIONS unless you include the ftape sources into
- the kernel source tree.
-- new vendors in `vendors.h':
- * HP Colorado T3000
- * ComByte DoublePlay (including a bug fix for their broken
- formatting software, thanks to whraven@njackn.com)
- * Iomega DITTO 2GIG. NOTE: this drive cannot work with ftape because
- the logical data layout of the cartridges used by this drive does
- NOT conform to the QIC standards, it is a special Iomega specific
- format. I've sent mail to Iomega but didn't receive an answer
- yet. If you want this drive to be supported by ftape, ask Iomega
- to give me information about it.
-- zftape:
- * re-introduced the MTIOC_ZFTAPE_GETBLKSZ ioctl for compatibility
- with zftape 1.06a and earlier. Please don't use it when writing
- new software, use the MTIOCVOLINFO ioctl instead.
- * Major overhaul of the code that updates the header segments. Never
- change the tape label unless erasing the tape. Thus we almost
- never need to write the header segments, unless we would modify
- the bad sector map which isn't done yet. Updating of volume table
- and compression map more secure now although it takes a bit
- longer.
- * Fixed bug when aborting a write operation with a signal: zftape
- now finishes the current volume (i.e. writes an eof marker) at the
- current position. It didn't before which led to somehow *strange*
- behavior in this cases.
- * Keep module locked in memory when using it with the non-rewinding
- devices and the tape is not logical at BOT. Needed for kerneld
- support.
-- sftape:
- * Keep module locked in memory when using it with the non-rewinding
- devices and the tape is not logical at BOT. Needed for kerneld
- support.
-
-===== Release notes for ftape-3.01, 14/11/96 =====
-
-- Fixed silly bugs in ftape-3.00:
- * MAKEDEV.ftape: major device number must be 27, not 23
- * sftape/sftape-read.c: sftape_read_header_segments() called
- itself recursively instead of calling ftape_read_header_segment()
- * zftape/qic-vtbl.h: conversion of ftape's file marks to zftape's
- internal volume table was broken.
- * patches/2.x.x/linux-2.0.21.dif: my RCS (resp. CVS) system replaced
- the `$Revison:' etc. macros in the `ftape.h' concerning part of the
- patch :-( Fixed.
- * info/ftape.info: Fixed misspellings (`cp' <-> `cp -r' etc.)
- * when ftape/sftape or ftape/zftape was compiled into the kernel the
- variable ftape_status was declared twice. Fixed.
- * removed reference to undeclared variable kernel_version when not
- compiling as module
- * fixed a bug introduced by the use of bit-fields for some flags
- (i.e. write_protected, no_cartridge, formatted)
- * flag `header_read' is now reset correctly to zero when tape is
- removed.
-- fixed a bug in sftape/sftape-eof.c that was already in the original
- ftape code. MTFSF/BSF was not handled correctly when positioned
- right before the file mark (think of tar)
-- Changed TRACE macros (following a suggestion of Marcin Dalecki) to use
- the predefined __FUNCTION__ macro of GCC. Spares about 4k of code.
-- added new vendor id for Iomega DITTO 2GIG
-- fixed a bug already present in zftape-1.06 when aborting a write
- with a signal: we now finish the current volume at that
- position. Header segments remain NOT up to date until an explicit call
- to MTREW or MTOFFL is done.
-
-===== Release notes for ftape-3.00, 14/10/96 =====
-
-- Merged ftape with zftape. There are three modules now:
- ftape for the hardware support, sftape for the implementation of the
- original ftape eof mark stuff and zftape that implements zftape's way
- of handling things (compression, volume table, tape blocks of
- constant length)
-- Documentation in TeXinfo format in the `info' subdirectory.
-- New ioctls for zftape. See zftape/zftape.h
-- Dummy formatting ioctl for ftape. See ftape.h
-- Kernel patch files for the 2.*.* series to include ftape-3.00 in the
- kernel source tree. These includes a kernel compatible Config.in
- script and fairly large online information for the kernel configure
- script.
-- Support for compiling with Linux-1.2.13.
-- Modified GNU mt from their cpio package that can handle the new
- ioctls.
-- ftape/sftape/zftape is kerneld save now!
-
-Notes on sftape:
-- sftape implements the eof handling code of the original ftape. If
- you like to stick with the original ftape stuff, you have to use
- this module, not zftape.
-- sftape is kerneld save, unlike the original ftape.
-- we keep the entire header segment now in memory, so no need to read
- it before updating the header segments. Additional memory
- consumption: 256 bytes.
-
-Notes for zftape:
-- zftape has support for tapes with format code 6 now, which use a
- slightly different volume table format compared with other floppy
- tapes.
-- new ioctls for zftape. Have a look at zftape/zftape.h
-- The internal volume table representation has changed for zftape. Old
- cartridges are converted automatically.
-- zftape no longer uses compression map segments, which have vanished
- from the QIC specs, but creates volume table entry that reserves
- enough space for the compression map.
-- zftape is kerneld save now.
-- we keep the entire header segment now in memory, so no need to read
- it before updating the header segments. Additional memory
- consumption: 256 bytes.
-
-Notes for contrib/gnumt:
-- modified mt from the GNU cpio package that supports all the new
- ioctls of zftape.
-Notes for contrib/swapout:
-- This contains the swapout.c program that was written by Kai
- Harrekilde-Pederson. I simply added a Makefile.
-
-===== Release notes for ftape-2.10, 14/10/96 =====
-
-The ftape maintainer has changed.
-Kai Harrekilde-Petersen <khp@dolphinics.no>
-has resigned from maintaining ftape, and I,
-Claus-Justus Heine <claus@momo.math.rwth-aachen.de>,
-have taken over.
-
-- Added support for tapes with `format code 6', i.e. QIC-3020 tapes
- with more than 2^16 segments.
-- merged changes made by Bas Laarhoven with ftape-2.09. Refer
- to his release notes below. I've included them into this
- file unchanged for your reference.
-- disabled call stack back trace for now. This new feature
- introduced by the interim release 2.0.x still seems to
- be buggy.
-- Tried to minimize differences between the ftape version
- to be included into the kernel source tree and the standalone
- module version.
-- Reintroduced support for Linux-1.2.13. Please refer to the
- Install-guide.
-
-===== Release notes for ftape-2.09, 16/06/96 =====
-
-There aren't any really big news in this release, mostly just that I
-(the maintainer) have changed my email address (due to a new job). My
-new address is <khp@dolphinics.no>
-
-- The CLK_48MHZ and FDC_82078SL options has gone (all 2Mbps cards seem
- to use a 48MHz oscillator anyway and I haven't heard of an 'SL
- chip out there).
-- The S82078B has been `downgraded' to i82077AA compability.
-- TESTING option revived. Right now, it'll enable the (seriously broken)
- 2Mbps code. If you enable it, you'll experience a tape drive that's
- *really* out to lunch!
-- Some (bold) changes in the init code. Please notify me if they
- break things for you.
-
-===== Release notes for ftape-2.08, 14/03/96 =====
-
-If you correct a problem with ftape, please send your patch to
-khp@dolphinics.no too.
-
-- Updated to reflect that NR_MEM_LISTS is gone in 1.3.74
-- Teac 700 added to list of known drives.
-- The registered device name is now "ft" rather than "ftape".
-
-===== Release notes for ftape-2.07a, 14/03/96 =====
-
-Bugfixes by Marcin Dalecki <dalecki@namu03.gwdg.de>:
-- In the last release it just compiled against 1.3.70;
- now the params to request_irq() and free_irq are() are fixed, so it also
- works in 1.3.73 :-)
-- Support for modules is now correct for newer kernels.
-
-===== Release notes for ftape-2.07, 04/03/96 =====
-
-
-- ftape updated to compile against 1.3.70.
-- Iomega 700 and Wangtek 3200 recognised.
-
-
-===== Release notes for ftape-2.06b, 13/02/96 =====
-
-Another simple bugfix version.
-
-- Jumbo 700 recognised.
-- Typo in vendors.h fixed.
-
-
-===== Release notes for ftape-2.06a, 10/02/96 =====
-
-This release is a simple bugfix version.
-
-- Linux/SMP: ftape *should* work.
-- FC-10/20: Only accepts IRQs 3-7, or 9. If IRQ 9, properly tell the card
- to use IRQ 2. Thanks to Greg Crider (gcrider@iclnet.org) for finding and
- locating this bug and testing the patch.
-- Insight drive recognised correctly again.
-- Motor-on wakeup version of the Iomega 250 drive added
-
-
-===== Release notes for ftape-2.06, 28/01/96 =====
-
-Special thanks go to Neal Friedman and Steven Sorbom for their
-help in producing and testing this release.
-
-I have continued to clean up the code, with an eye towards inclusion
-of ftape in Linus' official kernel (In fact, as I type this, I am
-running on a kernel with ftape support statically linked). I have
-test-compiled ftape against my 1.2.13 tree without problems.
-Hopefully, everything should be OK for the v1.2.x people.
-
-WARNING! Alan Cox has mailed me that ftape does *NOT* work with
-Linux/SMP. If you try to run ftape under Linux/SMP, it will cause a
-kernel deadlock (which is worse than a panic).
-
-- QIC-3020/TR-3: 1Mbps support works. Neal is capable of reading and
- writing data to a tape. ftape will automatically detect the type of
- tape (e.g. TR-3 vs QIC-80) and move the fdc in and out of
- "perpendicular mode" as necessary.
-- 2Mbps support is disabled by default, since it is not fully
- debugged. If you are adventurous, remove -DFDC_82078SL in the
- Makefile and see what happens :-)
-- fdc detection: silly bugs removed (Only 2Mbps fdcs were affected)
- and added detection of the National Semiconductors PC8744 fdc chip
- (used in the PC873xx "super-IO" chips).
-- Removed warning about incompatible types when compiling with Linux
- 1.2.x.
-- README.PCI updated with info about the DELL Dimension XPS P90.
-- Connor TST3200R added to detected drives.
-- `swapout' utility added to distribution. It will dirty 5Meg of
- memory, trying to swap out other programs. Just say `make swapout'
- to build it. ftape will do this automatically Real Soon Now (ie:
- when I have found out which kernel memory alloc function to call).
-
-
-===== Release notes for ftape-2.05, 08/01/96 =====
-
-- For v1.2.x Kernels, you must apply the patch linux-1.2/ksyms.patch to
- the kernel and rebuild it (it adds the __get_dma_pages symbol to
- ksyms.c).
-- Included new asm-i386/io.h file from v1.3.x kernel series, to enable
- gcc v.2.7.[12] to compile v1.2.x kernels (linux-1.2/io.h).
-- Module versions: If you wish to compile ftape as a versioned module,
- you must first compile your kernel with CONFIG_MODVERSIONS=y.
- Otherwise, you will get complaints that <linux/modversions.h> does not
- exist (if that happens, a `touch modversions.h' will help you out).
-- CLK_48MHZ: new define in the Makefile (default: non-zero). If you have
- a tape controller card that uses the i82078(-1) chip, but cannot get
- it to work with ftape, try set it to 0 (and please report this).
-- QIC-3010/3020: Complete support is still missing, but will hopefully
- come soon. Steven Sorbom has kindly provided me with hints about
- this. Writing of QIC-3020 tapes definitely does NOT work (do not try
- it! - the drive will not be in "perpendicular mode" and this will ruin
- the formatting info on the tape).
-- ftape_num_buffers is out of fashion: use NR_BUFFERS instead (and
- recompile if you want to change it :-).
-
-
-===== Release notes for ftape-2.04, 01/01/96 =====
-
-This version by Kai Harrekilde-Petersen <khp@dolphinics.no>
-
-- ALERT! Support for Kernels earlier then v1.1.85 is about to go away.
- I intend to clean up some of the code (getting rid of an annoyingly
- large numbers of #ifdef mostly), which means that support for
- pre-1.1.85 kernels must go as well.
-- NR_FTAPE_BUFFERS is gone; You can instead select the number of dma
- buffers by saying `insmod ftape.o ftape_num_buffer=<n>' instead.
-- Configure script gone. ftape will now automagically determine your
- kernel version by /usr/include/linux/version.h instead.
-- CONFIG_MODVERSIONS now work. All combinations of versioned /
- unversioned kernel and ftape module works (at least with my 1.3.52
- kernel).
-- If you have problems with inserting ftape into an old (1.2.x)
- kernel (e.g. insmod says "1.2.8 does not match 1.2.8), recompile
- your modules utilities with your new compiler.
-- Reveal TB1400 drive added to vendors.h
-- Support for the i82078-1 (2Mbps) chip is coming along. The
- biggest problem is that I don't have such a card, which makes
- testing / debugging somewhat problematic. The second biggest
- problem is that I do not have the QIC-3010/3020 standards either.
- Status right now is that the chip is detected, and it should be
- possible to put it into 2Mbps mode. However, I do not know what
- "extras" are needed to complete the support. Although putting the
- i82078 into 1Mbps mode ought to work out of the box, it doesn't
- (right now, ftape complains about id am errors).

-
-===== Release notes for ftape-2.04beta5, 29/12/95 =====
-
-Bas offline linux-tape
-----------------------
-For reasons only known to the majordomo mail list processor, Bas was
-kicked off the linux-tape list sometime during the summer. Being
-overworked at his for-pay job, he didn't notice it much. Instead I
-(Kai, khp@dolphinics.no) has worked on ftape to produce the 2.04(beta)
-version.
-
-zftape
-------
-Note that there exists a much improved version of ftape, written by
-Claus-Justus Heine <claus@willi.math.rwth-aachen.de> which is named
-zftape, which conforms to the QIC-80 specs on how to mark backups, and
-is capable of doing automatic compression. However, zftape makes
-substantial changes to ftape, and I (Kai) have therefore declined to
-integrate zftape into ftape. Hopefully, this will happen soon.
-
-CONFIG_QIC117 removed from the kernel
--------------------------------------
-The biggest change of all is that ftape now will allocate its dma
-buffers when it is inserted. The means that the CONFIG_QIC117 option
-has disappeared from the Linux kernel as of v1.3.34. If you have an
-earlier kernel, simply answer 'no' to the question will do the trick
-(if you get complains about __get_free_pages() missing, contact the
-linux-tape mailing list).
-
-Note that ftape-2.04beta will work equally well on kernels with and
-without `ftape support'. The only catch is, that you will waste
-around 96-128Kb of precious DMA'able memory on a box that has ftape
-support compiled in.
-
-Now for the real changes:
-
-- FC-20 can now use DMA channels 1, 2, and 3. Thanks to Daniel
- Cohen, catman@wpi.edu.
-- ftape no longer requires a (gigantic) 96Kb buffer to be statically
- allocated by the kernel.
-- Added new Iomega drive (8882) to vendors.h
-- -fno-strength-reduce added to Makefile, since GCC is broken.
-- i82078-1 (2Mbps) FDC support started.
-
-
-===== Release notes for ftape-2.03b, 27/05/95 =====
-
-- Prevented verify_area to return error if called with zero length.
-- Fixed a bug in flush_buffers that caused too much padding to be
- written when a final segment had bad sectors.
-- Increased maximum fast-seek overshoot value from 5 to 10 segments.
-- Breaking loop after 5 retries when positioning fails.
-- Fixed wrong calculation of tape length for QIC-3010 and QIC-3020
- tapes (densities were swapped).
-- Fixed wrong calculation of overshoot on seek_forward: Wrong sign
- of error.
-- Suppress (false) error message due to new tape loaded.
-- Added two new CMS drives (11c3 and 11c5) to vendors.h.
-
-
-===== Release notes for ftape-2.03a, 09/05/95 =====
-
-- Fixed display of old error (even if already cleared) in ftape_open.
-- Improved tape length detection, ioctls would fail for 425 ft tapes.
- Until the tape length is calculated with data from the header
- segment, we'll use worst-case values.
-- Clear eof_mark after rewinding ioctls.
-- Fixed wrong version message (2.03 had 2.02g id).
-- Fixed bug that caused the fdc to be reset very frequently.
- This shouldn't affect normal operation but the timing of the
- report routines has changed again and that may cause problems.
- We'll just have to find out....
-- Implemented correct write precompensation setting for QIC-3010/3020.
-- Cleaned up fdc_interrupt_wait routine. Hope it still works :-)
-- Finally removed (already disabled) special eof mark handling for
- gnu tar.
-- Changed order of get_dma_residue and disable_dma in fdc-isr.c
- because the current order would fail on at least one system.
- We're back to the original order again, hope (and expect) this
- doesn't break any other system.
-
-
-===== Release notes for ftape-2.03, 07/05/95 =====
-
-(Changes refer to the first ftape-2.02 release)
-
-Support for wide and extended length tapes
-------------------------------------------
-The Conner TSM 420 and 850 drives are reported to be working.
-I haven't received any reports about other brands; the TSM 420
-and 850 seem to be the most widely used wide drives.
-Extended length tapes (425 ft) with normal QIC-80 drives
-are operating too (At least I've had no reports stating otherwise).
-_Not_ yet completely supported (although they may work) are
-QIC-3020 drives and 2 Mbps floppy disk controllers won't work at
-the highest speed.
-If someone is kind enough to send me one of these, I'll include
-support for it too ;-)
-
-Easier configuration
---------------------
-Problems due to wrong settings in the Makefile are prevented
-by using a configuration script that sets the necessary (kernel
-version dependent) compile time options.
-This kernel version is now determined from the sources found
-at /usr/src/linux, or if not found, the old way using
-/proc/version.
-Versioned modules will be used automatically when supported
-by- and configured in- the kernel.
-Note that the current modules code (1.1.87) is still broken
-and _needs_ the fix included in the insmod directory.
-Please don't send me any more Oops reports caused by insmod :-(
-
-Reduced module size
--------------------
-The standard module size is much reduced and some compile time
-options can even reduce it further. (I don't recommend this
-for normal use but it can be handy for rescue diskettes)
-
-Option: Approx. module size:
-
-<standard> 150 Kb
-NO_TRACE 125 Kb
-NO_TRACE_AT_ALL 67 Kb
-
-
-Much improved driver interruption
----------------------------------
-Most possible loops have been broken and signal detection
-has been improved.
-In most cases the driver can be aborted by ^C (SIGINT) and
-SIGKILL (kill -9) will generate be a sure kill.
-(Note that aborting a tape operation may damage the last
-data written to tape)
-
-Improved error recovery
------------------------
-Ftape now returns an error (ENODATA) to the application if
-a segment proves to be unrecoverable and then skips the
-bad segment.
-This causes most applications to continue to work (tar
-and afio) loosing only a small amount (up to 29 Kb) of data.
-Retried read operations will now be done slightly off-track
-to improve the chance of success. Serious head off-track
-errors will be detected.
-
-FC-10 and FC-20 controllers
----------------------------
-Ftape now supports both the old CMS FC-10 and the newer FC-20
-controllers.
-Because the operation of these cards is still undocumented,
-thus far they will only work with the default settings (See
-Makefile). Any feed-back on how to use them with other settings
-will be welcome !
-Compilation will fail if one changes the settings to illegal
-values.
-
-Kernels and compilers
----------------------
-Ftape is currently being developed using the 2.5.8 compiler.
-The older 2.4.5 probably works too (Set option in Makefile!).
-I have no experience with any later compilers nor Elf support.
-Any information on this is welcome.
-The latest kernel I have tested ftape with is 1.2.6.
-
-Compression
------------
-An impressive collection of changes for ftape including
-on-the-fly compression is still lying on my desk.
-If 2.03 proves to be reliable I might start integrating these
-but as usual, I'm short in time :-(
-
-Formatting
-----------
-There is still no way to format tapes under Linux. As far as
-I know all attempts to write such a program have died now.
-Since formatted tapes are rather common now, I think all we
-need is a utility that writes a worst case pattern and verifies
-that with the drive put in verify mode, reducing margins.
-Any takers ?
-
-Furthermore
------------
-Cleaned up messages.
-Prepared to support multiple tape drives on one fdc.
-Thanks to all the people who sent bug reports and helped me
-improve the driver. Without trying to be complete I'll mention
-Gary Anderson (without his accurate reports and unreliable
-hardware there wouldn't be a 2.03), Stefan Kneifel (FC-20),
-Robert Broughton (FC-20, you were almost there ;-), Bjorn
-Ekwall (for the versioned modules and buggy insmod ;-), Peter
-Fox, Christopher Oliver, Ralph Whittaker and not the least
-Linus Torvalds (for Linux and keeping me busy because of
-changes to the kernel ;-)
-Thanks to anyone I forgot, for the bug reports, the ftape
-bashing and the mental support...
-
-
-That's it for now. Have Fun,
-
-Bas.
-
-
-===== Release notes for ftape-2.02g, 06/05/95 =====

- that take very long to start or stop.
-- Let use of get/set i/o-regions depend on kernel version.
-- Changed code to use a more general test for conditional
- compilations depending on kernel version.
-- Improved micro-step functionality to go off-track only
- while reading (id & data).
-- Added failure on tape-not-referenced bit in ftape_command.
-- Added FOREVER option to read-wait routine.
-- Changed read-id to use shorter timeout causing smaller
- rewinds on timeout.
-- Made kernel-interface functions static.
-
-
-===== Release notes for ftape-2.02f, 03/05/95 =====
-
-- Added support for dual tape drives on my system, extended Configure
- script to detect host 'dodo'.
-- Log media defect in history if ecc failed and no data was returned.
-- Fixed Configure script that was failing for kernel versions with
- double digit version or revision numbers.
-
-
-===== Release notes for ftape-2.02e, 01/05/95 =====
-
-- Fixed reposition loop at logical eot (failing read_id).
-- Fixed 34 segment offset when rewinding.
-- Added fast seek capability for more than 255 segments.
-- Fixed wrong busy result from ftape_command causing reverse
- seek to fail.
-- Added breakout from infinite rewind loop (if something fails).
-
-
-===== Release notes for ftape-2.02d, 30/04/95 =====
-
-- Improved abortion on signals: Interrupt will make a graceful
- exit, Kill will be less nice and should be used if everything
- else fails.
-- Included check for tape-head off track.
-- Implemented exit from tape-start loop.
-- Added kernel io-port registration.
-- Implemented skip of failing segment (ENODATA) on ecc failure.
- This allows afio and tar to continue when the tape is damaged.
-- Made distinction between drive names with different codes.
-
-
-===== Release notes for ftape-2.02c, 22/04/95 =====
-
-- Fixed too tight command queueing after tape stop/pause command
- issued from within interrupt service routine (Showed as timeout
- on Acknowledge errors during retries on some systems)
-- Tried to fix timeouts when using 425 ft tape because the extended
- length doesn't seem to be detected by the hardware.
- We now use the format code from the header segment so adjust the
- timing after reading the header segment.
-- Fixed some messages stating 'unexpected something...' being not
- unexpected anymore.
-- Started preparations for merge of dynamic buffer allocation and
- compression code.
-- Changed some debug messages to include relevant segment information
- at level 4.
-- Included early bail-out when drive offline, preventing a lot of
- false messages.
-- Moved ftape_parameter_xxx() offsets into function instead of in calls.
-- Removed 'weird, drive busy but no data' error when caused by
- an error during a read-id.
-- Improved 'timeout on acknowledge' diagnostics.
-- Moved MODULE option into Configure.
-- Reduced code size when no tracing at all was set (Claus Heine).
-- No longer log error code 0 (no error) as an error.
-
-
-===== Release notes for ftape-2.02b, 09/04/95 =====
-
-- Relaxed timing for status operation and displaying
- abnormal results. Hopefully this shows what's going
- wrong with the Conner TSM850R drives.
-- Created script for configuration, using version number
- of kernel source if available, otherwise /proc/version.
-- Fixed conditionals in kernel-interface.c.
-- Removed unavoidable TRACE output.
-
-
-===== Release notes for ftape-2.02a, 01/04/95 =====
-
-- Implemented `new-style' (versioned) modules support for new
- kernels.
-- Reduced size of module by moving static data to bss.
-- Now using version number of kernel source instead of running
- kernel for kernel versions >= 1.1.82
-- Added feedback on drive speeds to vendor information.
-- Included fixed insmod sources to distribution (Let's hope
- the modules distribution get fixed soon :-/).
-
-Note that I haven't yet implemented any of the code extension I
-received. I hope to find some time to do this soon.
-
-
-===== Release notes for ftape-2.02, 15/01/95 =====
-
-
-- Fixed failing repositioning when overshoot was incremented.
-- Fixed rate selection: Because of a deficiency in the QIC-117
- specification one cannot distinguish between a not implemented
- and a failing command. Therefor we now try to find out if the
- drive does support this command before usage.
-- Fixed error retry using wrong offset in fdc-isr.
-- Improved retry code to retry only once on a single no-data
- error in a segment.
-- Validate sector number extracted from eof mark because an
- invalid file mark (due to ???) could cause kernel panic.
-- Split ftape-io.c into ftape-io.c and ftape-ctl.c files.
-- Corrected too high media error count after writing to
- a bad tape.
-- Added #include <asm/segment.h> again because old kernel versions
- need it.
-- Fixed fdc not being disabled when open failed because no tape
- drive was found.
-- Fixed problem with soft error in sector 32 (shift operator with
- shiftcount 32 is not defined).
-
-
-===== Release notes for ftape-2.01, 08/01/95 =====
-
-
-- Removed TESTING setting from distributed Makefile.
-- Fixed `mt asf' failure: Rewind was deferred to close which
- overruled the fsf ioctl.
-- Prevented non-interruptible commands being interrupted.
-- Added missing timeout.pause setting.
-- Maximum tape speed read from drive type information table.
- If the information is not in the table (0) the drive will
- determine the speed itself and put a message in the logfile.
- This information should then be added to the table in the
- vendors.h file (and reported to me).
-- Added call to ftape_init_drive after soft reset for those
- (antique) drives that don't do an implicit seek_load_point
- after a reset or power up.
-- Don't try to set data rate if reset failed.
-- Prevent update of seek variables when starting from the
- beginning or the end of the tape.
-- Fixed wrong adjustment of overshoot in seek_forward().
-- Added sync to Makefile (again).
-- Added code to diagnose timer problems (calibr.c).
-- Replaced time differences by timediff calls.
-- Removed reference to do_floppy from object for recent kernels.
-- Fixed wrong display of 'failing dma controller' message.
-- Removed various no longer used #include statements.
-- Added max. tape speed value to vendor-struct.
-- Changed ftape-command to check pre-conditions and wait
- if needed.
-- Further updated qic117.h to rev G.
-- Combined command name table and restrictions table to one.
- Extended this table with some new fields.
-- Increased timeout on Ack timer value and included code to
- report out of spec behaviour.
-- Increased rewind timeout margin to calculated + 20%.
-- Improved data rate selection so it won't fail on some
- older (pre standard) drives.
-- Changed initialisation code so drive will be rewound if the
- driver is reloaded and the tape is not at bot.
-- Moved some of the flush operations from close to the ioctls.
-- Added exit code value to failing verify area message.
-- Loop until tape halted in smart-stop.
-- Fast seek handled specially if located at bot or eot.
-- Being more conservative on overshoot value.
-
-
-===== Release notes for ftape-2.00, 31/12/94 =====
-
- The Install-guide is completely rewritten and now also includes
-some information on how to use the driver. If you're either new
-to ftape or new to Unix tape devices make sure to read it !
-
- If you own a pci system and experience problems with the
-ftape driver make sure to read the README.PCI file. It contains
-some hints on how to fix your hardware.
-
- For anybody who hasn't noticed: The version number of the
-driver has been incremented (The latest released version has
-been version 1.14d).
- This has been done for two major reasons:
-
- o A new (better) error recovery scheme is implemented.
- o Support for new drive types has been added.
-
- All these improvements/changes will probably include a couple
-of new (and old?) bugs. If you encounter any problems that you think
-I'm not yet aware of, feel free to send a report to <bas@vimec.nl>.
- I recommend keeping a version of ftape-1.14d available, just
-in case ;-)
-
- This version should work with all kernel versions from 1.0.9 up
-to 1.1.72 (and probably earlier and later versions too).
-
-
-Major new features:
-
-- Better handling of tapes with defects: When a sector repeatedly
- (SOFT_RETRIES in ftape.h) cannot be written to or read from it is
- marked as an hard error and gets skipped.
- The error correction code can handle up to three of these hard
- errors provided there are no other errors in that segment (32 Kb).
-
-- Allows writing to tapes with defects (although the risk of loosing
- data increases !)
- Look for the media-defects entry printed with the statistics when
- the tape is closed. A non-zero value here shows a bad tape.
- [the actual count is wrong (too high), this is a known bug].
-
-- Use of backup header segment if first one is failing.
-
-- Support for extended length tapes with QIC-80: both 425 and 1100 ft.
- 0.25 inch tapes are now recognized and handled.
-
-- Support for new QIC-80 drives with 8 mm `wide' tapes (e.g. Conner
- TSM 420).
-
-- Support for new QIC-3010 and QIC-3020 drives (experimental) with
- both 0.25 inch and 8 mm tapes.
-
-Some minor features were added, a couple of small bugs were fixed and
-probably some new ones introduced ;-).
-
-[lseek() didn't make it into this version]
-
-Have fun,
-
-Bas.

-/* BRIEF DESCRIPTION OF THE LZRW3 ALGORITHM */
-/* ======================================== */
-/* The LZRW3 algorithm is identical to the LZRW1-A algorithm except that */
-/* instead of transmitting history offsets, it transmits hash table indexes. */
-/* In order to decode the indexes, the decompressor must maintain an */
-/* identical hash table. Copy items are straightforward:when the decompressor */
-/* receives a copy item, it simply looks up the hash table to translate the */
-/* index into a pointer into the data already decompressed. To update the */
-/* hash table, it replaces the same table entry with a pointer to the start */
-/* of the newly decoded phrase. The tricky part is with literal items, for at */
-/* the time that the decompressor receives a literal item the decompressor */
-/* does not have the three bytes in the Ziv (that the compressor has) to */
-/* perform the three-byte hash. To solve this problem, in LZRW3, both the */
-/* compressor and decompressor are wired up so that they "buffer" these */
-/* literals and update their hash tables only when three bytes are available. */
-/* This makes the maximum buffering 2 bytes. */
-/* */
-/* Replacement of offsets by hash table indexes yields a few percent extra */
-/* compression at the cost of some speed. LZRW3 is slower than LZRW1, LZRW1-A */
-/* and LZRW2, but yields better compression. */
-/* */
-/* Extra compression could be obtained by using a hash table of depth two. */
-/* However, increasing the depth above one incurs a significant decrease in */
-/* compression speed which was not considered worthwhile. Another reason for */
-/* keeping the depth down to one was to allow easy comparison with the */
-/* LZRW1-A and LZRW2 algorithms so as to demonstrate the exact effect of the */
-/* use of direct hash indexes. */

-/* The diagram above for LZRW3 looks almost identical to the diagram for */
-/* LZRW1. The difference is that in LZRW3, the compressor transmits hash */

-/* decompressor must maintain a hash table as well as the compressor and both */
-/* compressor and decompressor must "buffer" literals, as the decompressor */
-/* cannot hash phrases commencing with a literal until another two bytes have */
-/* arrived. */
-/* */
-/* LZRW3 Algorithm Execution Summary */
-/* --------------------------------- */
-/* 1. Hash the first three bytes of the Ziv to yield a hash table index h. */
-/* 2. Look up the hash table yielding history pointer p. */
-/* 3. Match where p points with the Ziv. If there is a match of three or */
-/* more bytes, code those bytes (in the Ziv) as a copy item, otherwise */
-/* code the next byte in the Ziv as a literal item. */
-/* 4. Update the hash table as possible subject to the constraint that only */
-/* phrases commencing three bytes back from the Ziv can be hashed and */
-/* entered into the hash table. (This enables the decompressor to keep */
-/* pace). See the description and code for more details. */

-/* */
-/* DEFINITION OF COMPRESSED FILE FORMAT */
-/* ==================================== */
-/* * A compressed file consists of a COPY FLAG followed by a REMAINDER. */
-/* * The copy flag CF uses up four bytes with the first byte being the */
-/* least significant. */
-/* * If CF=1, then the compressed file represents the remainder of the file */
-/* exactly. Otherwise CF=0 and the remainder of the file consists of zero */
-/* or more GROUPS, each of which represents one or more bytes. */
-/* * Each group consists of two bytes of CONTROL information followed by */
-/* sixteen ITEMs except for the last group which can contain from one */
-/* to sixteen items. */
-/* * An item can be either a LITERAL item or a COPY item. */
-/* * Each item corresponds to a bit in the control bytes. */
-/* * The first control byte corresponds to the first 8 items in the group */
-/* with bit 0 corresponding to the first item in the group and bit 7 to */
-/* the eighth item in the group. */
-/* * The second control byte corresponds to the second 8 items in the group */
-/* with bit 0 corresponding to the ninth item in the group and bit 7 to */
-/* the sixteenth item in the group. */
-/* * A zero bit in a control word means that the corresponding item is a */
-/* literal item. A one bit corresponds to a copy item. */
-/* * A literal item consists of a single byte which represents itself. */
-/* * A copy item consists of two bytes that represent from 3 to 18 bytes. */
-/* * The first byte in a copy item will be denoted C1. */
-/* * The second byte in a copy item will be denoted C2. */
-/* * Bits will be selected using square brackets. */
-/* For example: C1[0..3] is the low nibble of the first control byte. */
-/* of copy item C1. */
-/* * The LENGTH of a copy item is defined to be C1[0..3]+3 which is a number */
-/* in the range [3,18]. */
-/* * The INDEX of a copy item is defined to be C1[4..7]*256+C2[0..8] which */
-/* is a number in the range [0,4095]. */
-/* * A copy item represents the sequence of bytes */
-/* text[POS-OFFSET..POS-OFFSET+LENGTH-1] where */
-/* text is the entire text of the uncompressed string. */
-/* POS is the index in the text of the character following the */
-/* string represented by all the items preceeding the item */
-/* being defined. */
-/* OFFSET is obtained from INDEX by looking up the hash table. */
-/* */
-/******************************************************************************/
-
-/* The following #define defines the length of the copy flag that appears at */
-/* the start of the compressed file. The value of four bytes was chosen */
-/* because the fast_copy routine on my Macintosh runs faster if the source */

-/* string. The decompressor does the same. This solution requires no extra */

-/* the same for the compressor and decompressor and contains at least */
-/* MAX_RAW_ITEM bytes. I chose consecutive decimal digits because they do not */

-/* */
-/* DEFINITION OF FUNCTION COMPRESS */
-/* =============================== */
-/* */
-/* Summary of Function Compress */
-/* ---------------------------- */
-/* The action that 'compress' takes depends on its first argument called */
-/* 'action'. The function provides three actions: */
-/* */
-/* - Return information about the algorithm. */
-/* - Compress a block of memory. */
-/* - Decompress a block of memory. */
-/* */
-/* Parameters */
-/* ---------- */
-/* See the formal C definition later for a description of the parameters. */
-/* */
-/* Constants */
-/* --------- */
-/* COMPRESS_OVERRUN: The constant COMPRESS_OVERRUN defines by how many bytes */
-/* an algorithm is allowed to expand a block during a compression operation. */
-/* */
-/* Although compression algorithms usually compress data, there will always */
-/* be data that a given compressor will expand (this can be proven). */
-/* Fortunately, the degree of expansion can be limited to a single bit, by */
-/* copying over the input data if the data gets bigger during compression. */
-/* To allow for this possibility, the first bit of a compressed */
-/* representation can be used as a flag indicating whether the */
-/* input data was copied over, or truly compressed. In practice, the first */
-/* byte would be used to store this bit so as to maintain byte alignment. */
-/* */
-/* Unfortunately, in general, the only way to tell if an algorithm will */
-/* expand a particular block of data is to run the algorithm on the data. */
-/* If the algorithm does not continuously monitor how many output bytes it */
-/* has written, it might write an output block far larger than the input */
-/* block before realizing that it has done so. */
-/* On the other hand, continuous checks on output length are inefficient. */
-/* */
-/* To cater for all these problems, this interface definition: */
-/* > Allows a compression algorithm to return an output block that is up to */
-/* COMPRESS_OVERRUN bytes longer than the input block. */
-/* > Allows a compression algorithm to write up to COMPRESS_OVERRUN bytes */
-/* more than the length of the input block to the memory of the output */
-/* block regardless of the length of the output block eventually returned. */
-/* This allows an algorithm to overrun the length of the input block in the */
-/* output block by up to COMPRESS_OVERRUN bytes between expansion checks. */
-/* */
-/* The problem does not arise for decompression. */
-/* */
-/* Identity Action */
-/* --------------- */
-/* > action must be COMPRESS_ACTION_IDENTITY. */
-/* > p_dst_len must point to a longword to receive a longword address. */
-/* > The value of the other parameters does not matter. */
-/* > After execution, the longword that p_dst_len points to will be a pointer */
-/* to a structure of type compress_identity. */
-/* Thus, for example, after the call, (*p_dst_len)->memory will return the */
-/* number of bytes of working memory that the algorithm requires to run. */
-/* > The values of the identity structure returned are fixed constant */
-/* attributes of the algorithm and must not vary from call to call. */
-/* */
-/* Common Requirements for Compression and Decompression Actions */
-/* ------------------------------------------------------------- */
-/* > wrk_mem must point to an unused block of memory of a length specified in */
-/* the algorithm's identity block. The identity block can be obtained by */
-/* making a separate call to compress, specifying the identity action. */
-/* > The INPUT BLOCK is defined to be Memory[src_addr,src_addr+src_len-1]. */
-/* > dst_len will be used to denote *p_dst_len. */
-/* > dst_len is not read by compress, only written. */
-/* > The value of dst_len is defined only upon termination. */
-/* > The OUTPUT BLOCK is defined to be Memory[dst_addr,dst_addr+dst_len-1]. */
-/* */
-/* Compression Action */
-/* ------------------ */
-/* > action must be COMPRESS_ACTION_COMPRESS. */
-/* > src_len must be in the range [0,COMPRESS_MAX_ORG]. */
-/* > The OUTPUT ZONE is defined to be */
-/* Memory[dst_addr,dst_addr+src_len-1+COMPRESS_OVERRUN]. */
-/* > The function can modify any part of the output zone regardless of the */
-/* final length of the output block. */
-/* > The input block and the output zone must not overlap. */
-/* > dst_len will be in the range [0,src_len+COMPRESS_OVERRUN]. */
-/* > dst_len will be in the range [0,COMPRESS_MAX_COM] (from prev fact). */
-/* > The output block will consist of a representation of the input block. */
-/* */
-/* Decompression Action */
-/* -------------------- */
-/* > action must be COMPRESS_ACTION_DECOMPRESS. */
-/* > The input block must be the result of an earlier compression operation. */
-/* > If the previous fact is true, the following facts must also be true: */
-/* > src_len will be in the range [0,COMPRESS_MAX_COM]. */
-/* > dst_len will be in the range [0,COMPRESS_MAX_ORG]. */
-/* > The input and output blocks must not overlap. */
-/* > Only the output block is modified. */
-/* > Upon termination, the output block will consist of the bytes contained */
-/* in the input block passed to the earlier compression operation. */

- * *
- * The following two functions "ftape_compress()" and *
- * "ftape_uncompress()" are the interface to the actual compression *
- * algorithm (i.e. they are calling the "compress()" function from *
- * the lzrw3 package for now). These routines could quite easily be *
- * changed to adopt another compression algorithm instead of lzrw3, *
- * which currently is used. *
- * *
- *****************************************************************************/

-/* called by zft_compress_write() to perform the compression. Must
- * return the size of the compressed data.
- *
- * NOTE: The size of the compressed data should not exceed the size of
- * the uncompressed data. Most compression algorithms have means
- * to store data unchanged if the "compressed" data amount would
- * exceed the original one. Mostly this is done by storing some
- * flag-bytes in front of the compressed data to indicate if it
- * is compressed or not. Thus the worst compression result
- * length is the original length plus those flag-bytes.
- *
- * We don't want that, as the QIC-80 standard provides a means
- * of marking uncompressed blocks by simply setting bit 15 of
- * the compressed block's length. Thus a compessed block can
- * have at most a length of 2^15-1 bytes. The QIC-80 standard
- * restricts the block-length even further, allowing only 29k -
- * 6 bytes.
- *
- * Currently, the maximum blocksize used by zftape is 28k.
- *
- * In short: don't exceed the length of the input-package, set
- * bit 15 of the compressed size to 1 if you have copied data
- * instead of compressing it.

-
- The entire guts of this program was written by dosemu, modified to
- record reads and writes to the ports in the 0x180-0x188 address space,
- while running the CMS program TAPE.EXE V2.0.5 supplied with the drive.
-
- Modified to use an array of addresses and generally cleaned up (made
- much shorter) 4 June 94, dosemu isn't that good at writing short code it
- would seem :-). Made independent of 0x180, but I doubt it will work
- at any other address.
-
- Modified for distribution with ftape source. 21 June 94, SJL.
-
- Modifications on 20 October 95, by Daniel Cohen (catman@wpi.edu):
- Modified to support different DMA, IRQ, and IO Ports. Borland's
- Turbo Debugger in virtual 8086 mode (TD386.EXE with hardware breakpoints
- provided by the TDH386.SYS Device Driver) was used on the CMS program
- TAPE V4.0.5. I set breakpoints on I/O to ports 0x180-0x187. Note that
- CMS's program will not successfully configure the tape drive if you set
- breakpoints on IO Reads, but you can set them on IO Writes without problems.
- Known problems:
- - You can not use DMA Channels 5 or 7.
-
- Modification on 29 January 96, by Daniel Cohen (catman@wpi.edu):
- Modified to only accept IRQs 3 - 7, or 9. Since we can only send a 3 bit
- number representing the IRQ to the card, special handling is required when
- IRQ 9 is selected. IRQ 2 and 9 are the same, and we should request IRQ 9
- from the kernel while telling the card to use IRQ 2. Thanks to Greg
- Crider (gcrider@iclnet.org) for finding and locating this bug, as well as
- testing the patch.
-
- Modification on 11 December 96, by Claus Heine (claus@momo.math.rwth-aachen.de):
- Modified a little to use variahle ft_fdc_base, ft_fdc_irq, ft_fdc_dma
- instead of preprocessor symbols. Thus we can compile this into the module
- or kernel and let the user specify the options as command line arguments.

-/* Notice: to minimize the potential for confusion, we use r to
- * denote the independent variable of the polynomials in the
- * Galois Field GF(2^8). We reserve x for polynomials that
- * that have coefficients in GF(2^8).
- *
- * The Galois Field in which coefficient arithmetic is performed are
- * the polynomials over Z_2 (i.e., 0 and 1) modulo the irreducible
- * polynomial f(r), where f(r)=r^8 + r^7 + r^2 + r + 1. A polynomial
- * is represented as a byte with the MSB as the coefficient of r^7 and
- * the LSB as the coefficient of r^0. For example, the binary
- * representation of f(x) is 0x187 (of course, this doesn't fit into 8
- * bits). In this field, the polynomial r is a primitive element.
- * That is, r^i with i in 0,...,255 enumerates all elements in the
- * field.
- *
- * The generator polynomial for the QIC-80 ECC is
- *
- * g(x) = x^3 + r^105*x^2 + r^105*x + 1
- *
- * which can be factored into:
- *
- * g(x) = (x-r^-1)(x-r^0)(x-r^1)
- *
- * the byte representation of the coefficients are:
- *
- * r^105 = 0xc0
- * r^-1 = 0xc3
- * r^0 = 0x01
- * r^1 = 0x02
- *
- * Notice that r^-1 = r^254 as exponent arithmetic is performed
- * modulo 2^8-1 = 255.
- *
- * For more information on Galois Fields and Reed-Solomon codes, refer
- * to any good book. I found _An Introduction to Error Correcting
- * Codes with Applications_ by S. A. Vanstone and P. C. van Oorschot
- * to be a good introduction into the former. _CODING THEORY: The
- * Essentials_ I found very useful for its concise description of
- * Reed-Solomon encoding/decoding.

- * There can be a total of 448 entries (1792 bytes).
- *
- * My guess is that no program is using this bad sector log (the *
- * format seems useless as there is no indication of the bad sector
- * itself, only the segment) However, if any program does use the bad
- * sector log, the format used by ftape will let the program think
- * there are some bad sectors and no harm is done.
- *
- * The eof mark entries that ftape stores in the bad sector log: even
- * 16-bit word: segment number of eof mark odd 16-bit word: sector
- * number of eof mark [1..32]
- *
- * The zft_eof_map as maintained is a sorted list of eof mark entries.
- *
- *
- * The tape name field in the header segments is used to store a linux
- * tape identification string and a version number. This way the tape
- * can be recognized as a Linux raw format tape when using tools under
- * other OS's.
- *
- * 'Wide' QIC tapes (format code 4) don't have a failed sector list
- * anymore. That space is used for the (longer) bad sector map that
- * now is a variable length list too. We now store our end-of-file
- * marker list after the bad-sector-map on tape. The list is delimited
- * by a (__u32) 0 entry.

+ * For P4SBx:
+ * BIOS setup -> Advanced -> Integrated Peripherals -> Watch Dog Feature
+ * For P4DPx:
+ * BIOS setup -> Advanced -> I/O Device Configuration -> Watch Dog
+ * This setting enables or disables Watchdog function. When enabled, the
+ * default watchdog timer is set to be 5 minutes (about 4’35”). It is
+ * enough to load and run the OS. The application (service or driver) has
+ * to take over the control once OS is running up and before watchdog
+ * expires.
+ *
+ * 2. JUMPER
+ * For P4SBx: JP39
+ * For P4DPx: JP37
+ * This jumper is used for safety. Closed is enabled. This jumper
+ * prevents user enables watchdog in BIOS by accident.
+ *
+ * To enable Watch Dog function, both BIOS and JUMPER must be enabled.
+ *
+ * The documentation lists motherboards P4SBx and P4DPx series as of
+ * 20-March-2002. However, this code works flawlessly with much newer
+ * motherboards, such as my X6DHR-8G2 (SuperServer 6014H-82).
+ *
+ * The original iTCO driver as written does not actually reset the
+ * watchdog timer on these machines, as a result they reboot after five
+ * minutes.
+ *
+ * NOTE: You may leave the Watchdog function disabled in the SuperMicro
+ * BIOS to avoid a "boot-race"... This driver will enable watchdog
+ * functionality even if it's disabled in the BIOS once the /dev/watchdog
+ * file is opened.

+ *
+ * History:
+ * 2003 - Created version 1.0 for Linux 2.4.x.
+ * 2006 - Ported to Linux 2.6, added nowayout and MAGICCLOSE
+ * features. Released version 1.1
+ *
+ * Theory of operation:
+ *
+ * A Watchdog Timer (WDT) is a hardware circuit that can
+ * reset the computer system in case of a software fault.
+ * You probably knew that already.
+ *
+ * Usually a userspace daemon will notify the kernel WDT driver
+ * via the /dev/watchdog special device file that userspace is
+ * still alive, at regular intervals. When such a notification
+ * occurs, the driver will usually tell the hardware watchdog
+ * that everything is in order, and that the watchdog should wait
+ * for yet another little while to reset the system.
+ * If userspace fails (RAM error, kernel bug, whatever), the
+ * notifications cease to occur, and the hardware watchdog will
+ * reset the system (causing a reboot) after the timeout occurs.
+ *
+ * Create device with:
+ * mknod /dev/watchdog c 10 130
+ *
+ * For an example userspace keep-alive daemon, see:
+ * Documentation/watchdog/watchdog.txt

+ *
+ * These operations represent the instruction emulator's interface to memory.
+ * There are two categories of operation: those that act on ordinary memory
+ * regions (*_std), and those that act on memory regions known to require
+ * special treatment or emulation (*_emulated).
+ *
+ * The emulator assumes that an instruction accesses only one 'emulated memory'
+ * location, that this location is the given linear faulting address (cr2), and
+ * that this is one of the instruction's data operands. Instruction fetches and
+ * stack operations are assumed never to access emulated memory. The emulator
+ * automatically deduces which operand of a string-move operation is accessing
+ * emulated memory, and assumes that the other operand accesses normal memory.
+ *
+ * NOTES:
+ * 1. The emulator isn't very smart about emulated vs. standard memory.
+ * 'Emulated memory' access addresses should be checked for sanity.
+ * 'Normal memory' accesses may fault, and the caller must arrange to
+ * detect and handle reentrancy into the emulator via recursive faults.
+ * Accesses may be unaligned and may cross page boundaries.
+ * 2. If the access fails (cannot emulate, or a standard access faults) then
+ * it is up to the memop to propagate the fault to the guest VM via
+ * some out-of-band mechanism, unknown to the emulator. The memop signals
+ * failure by returning X86EMUL_PROPAGATE_FAULT to the emulator, which will
+ * then immediately bail.
+ * 3. Valid access sizes are 1, 2, 4 and 8 bytes. On x86/32 systems only
+ * cmpxchg8b_emulated need support 8-byte accesses.
+ * 4. The emulator cannot handle 64-bit mode emulation on an x86/32 system.

+ * Updates to driver completed by Dwaine P. Garden
+ *
+ *
+ * TODO:
+ * - use submit_urb for all setup packets
+ * - Fix memory settings for nt1004. It is 4 times as big as the
+ * nt1003 memory.
+ * - Add audio on endpoint 3 for nt1004 chip. Seems impossible, needs a codec interface. Which one?
+ * - Clean up the driver.
+ * - optimization for performance.
+ * - Add Videotext capability (VBI). Working on it.....
+ * - Check audio for other devices

- This is the chip-specific code for many 8390-based ethernet adaptors.
- This is not a complete driver, it must be combined with board-specific
- code such as ne.c, wd.c, 3c503.c, etc.
-
- Seeing how at least eight drivers use this code, (not counting the
- PCMCIA ones either) it is easy to break some card by what seems like
- a simple innocent change. Please contact me or Donald if you think
- you have found something that needs changing. -- PG
-
-
- Changelog:
-
- Paul Gortmaker : remove set_bit lock, other cleanups.
- Paul Gortmaker : add ei_get_8390_hdr() so we can pass skb's to
- ei_block_input() for eth_io_copy_and_sum().
- Paul Gortmaker : exchange static int ei_pingpong for a #define,
- also add better Tx error handling.
- Paul Gortmaker : rewrite Rx overrun handling as per NS specs.
- Alexey Kuznetsov : use the 8390's six bit hash multicast filter.
- Paul Gortmaker : tweak ANK's above multicast changes a bit.
- Paul Gortmaker : update packet statistics for v2.1.x
- Alan Cox : support arbitary stupid port mappings on the
- 68K Macintosh. Support >16bit I/O spaces
- Paul Gortmaker : add kmod support for auto-loading of the 8390
- module by all drivers that require it.
- Alan Cox : Spinlocking work, added 'BUG_83C690'
- Paul Gortmaker : Separate out Tx timeout code from Tx path.
- Paul Gortmaker : Remove old unused single Tx buffer code.
- Hayato Fujiwara : Add m32r support.
- Paul Gortmaker : use skb_padto() instead of stack scratch area
-

- * SMP and the 8390 setup.
- *
- * The 8390 isnt exactly designed to be multithreaded on RX/TX. There is
- * a page register that controls bank and packet buffer access. We guard
- * this with ei_local->page_lock. Nobody should assume or set the page other
- * than zero when the lock is not held. Lock holders must restore page 0
- * before unlocking. Even pure readers must take the lock to protect in
- * page 0.
- *
- * To make life difficult the chip can also be very slow. We therefore can't
- * just use spinlocks. For the longer lockups we disable the irq the device
- * sits on and hold the lock. We must hold the lock because there is a dual
- * processor case other than interrupts (get stats/set multicast list in
- * parallel with each other and transmit).
- *
- * Note: in theory we can just disable the irq on the card _but_ there is
- * a latency on SMP irq delivery. So we can easily go "disable irq" "sync irqs"
- * enter lock, take the queued irq. So we waddle instead of flying.
- *
- * Finally by special arrangement for the purpose of being generally
- * annoying the transmit function is called bh atomic. That places
- * restrictions on the user context callers as disable_irq won't save
- * them.

+
+
+ This is the chip-specific code for many 8390-based ethernet adaptors.
+ This is not a complete driver, it must be combined with board-specific
+ code such as ne.c, wd.c, 3c503.c, etc.
+
+ Seeing how at least eight drivers use this code, (not counting the
+ PCMCIA ones either) it is easy to break some card by what seems like
+ a simple innocent change. Please contact me or Donald if you think
+ you have found something that needs changing. -- PG
+
+
+ Changelog:
+
+ Paul Gortmaker : remove set_bit lock, other cleanups.
+ Paul Gortmaker : add ei_get_8390_hdr() so we can pass skb's to
+ ei_block_input() for eth_io_copy_and_sum().
+ Paul Gortmaker : exchange static int ei_pingpong for a #define,
+ also add better Tx error handling.
+ Paul Gortmaker : rewrite Rx overrun handling as per NS specs.
+ Alexey Kuznetsov : use the 8390's six bit hash multicast filter.
+ Paul Gortmaker : tweak ANK's above multicast changes a bit.
+ Paul Gortmaker : update packet statistics for v2.1.x
+ Alan Cox : support arbitary stupid port mappings on the
+ 68K Macintosh. Support >16bit I/O spaces
+ Paul Gortmaker : add kmod support for auto-loading of the 8390
+ module by all drivers that require it.
+ Alan Cox : Spinlocking work, added 'BUG_83C690'
+ Paul Gortmaker : Separate out Tx timeout code from Tx path.
+ Paul Gortmaker : Remove old unused single Tx buffer code.
+ Hayato Fujiwara : Add m32r support.
+ Paul Gortmaker : use skb_padto() instead of stack scratch area

+ * than zero when the lock is not held. Lock holders must restore page 0
+ * before unlocking. Even pure readers must take the lock to protect in
+ * page 0.
+ *
+ * To make life difficult the chip can also be very slow. We therefore can't
+ * just use spinlocks. For the longer lockups we disable the irq the device
+ * sits on and hold the lock. We must hold the lock because there is a dual
+ * processor case other than interrupts (get stats/set multicast list in
+ * parallel with each other and transmit).
+ *
+ * Note: in theory we can just disable the irq on the card _but_ there is
+ * a latency on SMP irq delivery. So we can easily go "disable irq" "sync irqs"
+ * enter lock, take the queued irq. So we waddle instead of flying.
+ *
+ * Finally by special arrangement for the purpose of being generally
+ * annoying the transmit function is called bh atomic. That places
+ * restrictions on the user context callers as disable_irq won't save

Version 1.46
------------
Support deep tree mounts. Better support OS/2, Win9x (DOS) time stamps.
+Allow null user to be specified on mount ("username="). Do not return
+EINVAL on readdir when filldir fails due to overwritten blocksize
+(fixes FC problem). Return error in rename 2nd attempt retry (ie report
+if rename by handle also fails, after rename by path fails, we were
+not reporting whether the retry worked or not). Fix NTLMv2 to
+work to Windows servers (mount with option "sec=ntlmv2").
Version 1.45
------------

+/*
+ * lowcomms.c
+ *
+ * This is the "low-level" comms layer.
+ *
+ * It is responsible for sending/receiving messages
+ * from other nodes in the cluster.
+ *
+ * Cluster nodes are referred to by their nodeids. nodeids are
+ * simply 32 bit numbers to the locking module - if they need to
+ * be expanded for the cluster infrastructure then that is it's
+ * responsibility. It is this layer's
+ * responsibility to resolve these into IP address or
+ * whatever it needs for inter-node communication.
+ *
+ * The comms level is two kernel threads that deal mainly with
+ * the receiving of messages from other nodes and passing them
+ * up to the mid-level comms layer (which understands the
+ * message format) for execution by the locking core, and
+ * a send thread which does all the setting up of connections
+ * to remote nodes and the sending of data. Threads are not allowed
+ * to send their own data because it may cause them to wait in times
+ * of high load. Also, this way, the sending thread can collect together
+ * messages bound for one node and send them in one block.
+ *
+ * I don't see any problem with the recv thread executing the locking
+ * code on behalf of remote processes as the locking code is
+ * short, efficient and never (well, hardly ever) waits.

+ * lowcomms.c
+ *
+ * This is the "low-level" comms layer.
+ *
+ * It is responsible for sending/receiving messages
+ * from other nodes in the cluster.
+ *
+ * Cluster nodes are referred to by their nodeids. nodeids are
+ * simply 32 bit numbers to the locking module - if they need to
+ * be expanded for the cluster infrastructure then that is it's
+ * responsibility. It is this layer's
+ * responsibility to resolve these into IP address or
+ * whatever it needs for inter-node communication.
+ *
+ * The comms level is two kernel threads that deal mainly with
+ * the receiving of messages from other nodes and passing them
+ * up to the mid-level comms layer (which understands the
+ * message format) for execution by the locking core, and
+ * a send thread which does all the setting up of connections
+ * to remote nodes and the sending of data. Threads are not allowed
+ * to send their own data because it may cause them to wait in times
+ * of high load. Also, this way, the sending thread can collect together
+ * messages bound for one node and send them in one block.
+ *
+ * I don't see any problem with the recv thread executing the locking
+ * code on behalf of remote processes as the locking code is
+ * short, efficient and never waits.

-/*
- * lowcomms.c
- *
- * This is the "low-level" comms layer.
- *
- * It is responsible for sending/receiving messages
- * from other nodes in the cluster.
- *
- * Cluster nodes are referred to by their nodeids. nodeids are
- * simply 32 bit numbers to the locking module - if they need to
- * be expanded for the cluster infrastructure then that is it's
- * responsibility. It is this layer's
- * responsibility to resolve these into IP address or
- * whatever it needs for inter-node communication.
- *
- * The comms level is two kernel threads that deal mainly with
- * the receiving of messages from other nodes and passing them
- * up to the mid-level comms layer (which understands the
- * message format) for execution by the locking core, and
- * a send thread which does all the setting up of connections
- * to remote nodes and the sending of data. Threads are not allowed
- * to send their own data because it may cause them to wait in times
- * of high load. Also, this way, the sending thread can collect together
- * messages bound for one node and send them in one block.
- *
- * I don't see any problem with the recv thread executing the locking
- * code on behalf of remote processes as the locking code is
- * short, efficient and never (well, hardly ever) waits.
- *

- Thanks to Andrzej Krzysztofowicz <ankry@mif.pg.gda.pl>

-
-Thu, 3 Dec 1998 Al Viro (viro@parcelfarce.linux.theplanet.co.uk)
- * namei.c (sysv_rmdir):
- Bugectomy: old check for victim being busy
- (inode->i_count) wasn't replaced (with checking
- dentry->d_count) and escaped Linus in the last round
- of changes. Shot and buried.
-
-Wed, 9 Dec 1998 AV
- * namei.c (do_sysv_rename):

- Removed checks that went to VFS.
- * namei.c (sysv_unlink):
- Removed checks that went to VFS.
-
-Thu, 10 Dec 1998 AV
- * namei.c (do_mknod):
- Removed dead code - mknod is never asked to
- create a symlink or directory. Incidentially,
- it wouldn't do it right if it would be called.
-
-Sat, 26 Dec 1998 KGB
- * inode.c (detect_sysv4):
- Added detection of expanded s_type field (0x10,
- 0x20 and 0x30). Forced read-only access in this case.
-
-Sun, 21 Mar 1999 AV
- * namei.c (sysv_link):
- Fixed i_count usage that resulted in dcache corruption.
- * inode.c:
- Filled ->delete_inode() method with sysv_delete_inode().
- sysv_put_inode() is gone, as it tried to do ->delete_
- _inode()'s job.
- * ialloc.c: (sysv_free_inode):
- Fixed race.
-
-Sun, 30 Apr 1999 AV
- * namei.c (sysv_mknod):

-
-and was merged together in July 1993.
-
-These filesystems are rather similar. Here is a comparison with Minix FS:
-
-* Linux fdisk reports on partitions
- - Minix FS 0x81 Linux/Minix
- - Xenix FS ??
- - SystemV FS ??
- - Coherent FS 0x08 AIX bootable
-
-* Size of a block or zone (data allocation unit on disk)
- - Minix FS 1024
- - Xenix FS 1024 (also 512 ??)
- - SystemV FS 1024 (also 512 and 2048)
- - Coherent FS 512
-
-* General layout: all have one boot block, one super block and
- separate areas for inodes and for directories/data.
- On SystemV Release 2 FS (e.g. Microport) the first track is reserved and
- all the block numbers (including the super block) are offset by one track.
-
-* Byte ordering of "short" (16 bit entities) on disk:
- - Minix FS little endian 0 1
- - Xenix FS little endian 0 1
- - SystemV FS little endian 0 1
- - Coherent FS little endian 0 1
- Of course, this affects only the file system, not the data of files on it!
-
-* Byte ordering of "long" (32 bit entities) on disk:
- - Minix FS little endian 0 1 2 3
- - Xenix FS little endian 0 1 2 3
- - SystemV FS little endian 0 1 2 3
- - Coherent FS PDP-11 2 3 0 1
- Of course, this affects only the file system, not the data of files on it!
-
-* Inode on disk: "short", 0 means non-existent, the root dir ino is:
- - Minix FS 1
- - Xenix FS, SystemV FS, Coherent FS 2
-
-* Maximum number of hard links to a file:
- - Minix FS 250
- - Xenix FS ??
- - SystemV FS ??
- - Coherent FS >=10000
-
-* Free inode management:
- - Minix FS a bitmap
- - Xenix FS, SystemV FS, Coherent FS
- There is a cache of a certain number of free inodes in the super-block.
- When it is exhausted, new free inodes are found using a linear search.
-
-* Free block management:
- - Minix FS a bitmap
- - Xenix FS, SystemV FS, Coherent FS
- Free blocks are organized in a "free list". Maybe a misleading term,
- since it is not true that every free block contains a pointer to
- the next free block. Rather, the free blocks are organized in chunks
- of limited size, and every now and then a free block contains pointers
- to the free blocks pertaining to the next chunk; the first of these
- contains pointers and so on. The list terminates with a "block number"
- 0 on Xenix FS and SystemV FS, with a block zeroed out on Coherent FS.
-
-* Super-block location:
- - Minix FS block 1 = bytes 1024..2047
- - Xenix FS block 1 = bytes 1024..2047
- - SystemV FS bytes 512..1023
- - Coherent FS block 1 = bytes 512..1023
-
-* Super-block layout:
- - Minix FS
- unsigned short s_ninodes;
- unsigned short s_nzones;
- unsigned short s_imap_blocks;
- unsigned short s_zmap_blocks;
- unsigned short s_firstdatazone;
- unsigned short s_log_zone_size;
- unsigned long s_max_size;
- unsigned short s_magic;
- - Xenix FS, SystemV FS, Coherent FS
- unsigned short s_firstdatazone;
- unsigned long s_nzones;
- unsigned short s_fzone_count;
- unsigned long s_fzones[NICFREE];
- unsigned short s_finode_count;
- unsigned short s_finodes[NICINOD];
- char s_flock;
- char s_ilock;
- char s_modified;
- char s_rdonly;
- unsigned long s_time;
- short s_dinfo[4]; -- SystemV FS only
- unsigned long s_free_zones;
- unsigned short s_free_inodes;
- short s_dinfo[4]; -- Xenix FS only
- unsigned short s_interleave_m,s_interleave_n; -- Coherent FS only
- char s_fname[6];
- char s_fpack[6];
- then they differ considerably:
- Xenix FS
- char s_clean;
- char s_fill[371];
- long s_magic;
- long s_type;
- SystemV FS
- long s_fill[12 or 14];
- long s_state;
- long s_magic;
- long s_type;
- Coherent FS
- unsigned long s_unique;
- Note that Coherent FS has no magic.
-
-* Inode layout:
- - Minix FS
- unsigned short i_mode;
- unsigned short i_uid;
- unsigned long i_size;
- unsigned long i_time;
- unsigned char i_gid;
- unsigned char i_nlinks;
- unsigned short i_zone[7+1+1];
- - Xenix FS, SystemV FS, Coherent FS
- unsigned short i_mode;
- unsigned short i_nlink;
- unsigned short i_uid;
- unsigned short i_gid;
- unsigned long i_size;
- unsigned char i_zone[3*(10+1+1+1)];
- unsigned long i_atime;
- unsigned long i_mtime;
- unsigned long i_ctime;
-
-* Regular file data blocks are organized as
- - Minix FS
- 7 direct blocks
- 1 indirect block (pointers to blocks)
- 1 double-indirect block (pointer to pointers to blocks)
- - Xenix FS, SystemV FS, Coherent FS
- 10 direct blocks
- 1 indirect block (pointers to blocks)
- 1 double-indirect block (pointer to pointers to blocks)
- 1 triple-indirect block (pointer to pointers to pointers to blocks)
-
-* Inode size, inodes per block
- - Minix FS 32 32
- - Xenix FS 64 16
- - SystemV FS 64 16
- - Coherent FS 64 8
-
-* Directory entry on disk
- - Minix FS
- unsigned short inode;
- char name[14/30];
- - Xenix FS, SystemV FS, Coherent FS
- unsigned short inode;
- char name[14];
-
-* Dir entry size, dir entries per block
- - Minix FS 16/32 64/32
- - Xenix FS 16 64
- - SystemV FS 16 64
- - Coherent FS 16 32
-
-* How to implement symbolic links such that the host fsck doesn't scream:
- - Minix FS normal
- - Xenix FS kludge: as regular files with chmod 1000
- - SystemV FS ??
- - Coherent FS kludge: as regular files with chmod 1000
-
-
-Notation: We often speak of a "block" but mean a zone (the allocation unit)
-and not the disk driver's notion of "block".

+ * Prototype: u64 cnt32_to_63(u32 cnt)
+ * Many hardware clock counters are only 32 bits wide and therefore have
+ * a relatively short period making wrap-arounds rather frequent. This
+ * is a problem when implementing sched_clock() for example, where a 64-bit
+ * non-wrapping monotonic value is expected to be returned.
+ *
+ * To overcome that limitation, let's extend a 32-bit counter to 63 bits
+ * in a completely lock free fashion. Bits 0 to 31 of the clock are provided
+ * by the hardware while bits 32 to 62 are stored in memory. The top bit in
+ * memory is used to synchronize with the hardware clock half-period. When
+ * the top bit of both counters (hardware and in memory) differ then the
+ * memory is updated with a new value, incrementing it when the hardware
+ * counter wraps around.
+ *
+ * Because a word store in memory is atomic then the incremented value will
+ * always be in synch with the top bit indicating to any potential concurrent
+ * reader if the value in memory is up to date or not with regards to the
+ * needed increment. And any race in updating the value in memory is harmless
+ * as the same value would simply be stored more than once.
+ *
+ * The only restriction for the algorithm to work properly is that this
+ * code must be executed at least once per each half period of the 32-bit
+ * counter to properly update the state bit in memory. This is usually not a
+ * problem in practice, but if it is then a kernel timer could be scheduled
+ * to manage for this code to be executed often enough.
+ *
+ * Note that the top bit (bit 63) in the returned value should be considered
+ * as garbage. It is not cleared here because callers are likely to use a
+ * multiplier on the returned value which can get rid of the top bit
+ * implicitly by making the multiplier even, therefore saving on a runtime
+ * clear-bit instruction. Otherwise caller must remember to clear the top
+ * bit explicitly.

+ * read_barrier_depends - Flush all pending reads that subsequents reads
+ * depend on.
+ *
+ * No data-dependent reads from memory-like regions are ever reordered
+ * over this barrier. All reads preceding this primitive are guaranteed
+ * to access memory (but not necessarily other CPUs' caches) before any
+ * reads following this primitive that depend on the data return by
+ * any of the preceding reads. This primitive is much lighter weight than
+ * rmb() on most CPUs, and is never heavier weight than is
+ * rmb().
+ *
+ * These ordering constraints are respected by both the local CPU
+ * and the compiler.
+ *
+ * Ordering is not guaranteed by anything other than these primitives,
+ * not even by data dependencies. See the documentation for
+ * memory_barrier() for examples and URLs to more information.
+ *
+ * For example, the following code would force ordering (the initial
+ * value of "a" is zero, "b" is one, and "p" is "&a"):
+ *
+ * <programlisting>
+ * CPU 0 CPU 1
+ *
+ * b = 2;
+ * memory_barrier();
+ * p = &b; q = p;
+ * read_barrier_depends();
+ * d = *q;
+ * </programlisting>
+ *
+ * because the read of "*q" depends on the read of "p" and these
+ * two reads are separated by a read_barrier_depends(). However,
+ * the following code, with the same initial values for "a" and "b":
+ *
+ * <programlisting>
+ * CPU 0 CPU 1
+ *
+ * a = 2;
+ * memory_barrier();
+ * b = 3; y = b;
+ * read_barrier_depends();
+ * x = a;
+ * </programlisting>
+ *
+ * does not enforce ordering, since there is no data dependency between
+ * the read of "a" and the read of "b". Therefore, on some CPUs, such
+ * as Alpha, "y" could be set to 3 and "x" to 0. Use rmb()
+ * in cases like this where there are no data dependencies.

- * read_barrier_depends - Flush all pending reads that subsequents reads
- * depend on.
- *
- * No data-dependent reads from memory-like regions are ever reordered
- * over this barrier. All reads preceding this primitive are guaranteed
- * to access memory (but not necessarily other CPUs' caches) before any
- * reads following this primitive that depend on the data return by
- * any of the preceding reads. This primitive is much lighter weight than
- * rmb() on most CPUs, and is never heavier weight than is
- * rmb().
- *
- * These ordering constraints are respected by both the local CPU
- * and the compiler.
- *
- * Ordering is not guaranteed by anything other than these primitives,
- * not even by data dependencies. See the documentation for
- * memory_barrier() for examples and URLs to more information.
- *
- * For example, the following code would force ordering (the initial
- * value of "a" is zero, "b" is one, and "p" is "&a"):
- *
- * <programlisting>
- * CPU 0 CPU 1
- *
- * b = 2;
- * memory_barrier();
- * p = &b; q = p;
- * read_barrier_depends();
- * d = *q;
- * </programlisting>
- *
- * because the read of "*q" depends on the read of "p" and these
- * two reads are separated by a read_barrier_depends(). However,
- * the following code, with the same initial values for "a" and "b":
- *
- * <programlisting>
- * CPU 0 CPU 1
- *
- * a = 2;
- * memory_barrier();
- * b = 3; y = b;
- * read_barrier_depends();
- * x = a;
- * </programlisting>
- *
- * does not enforce ordering, since there is no data dependency between
- * the read of "a" and the read of "b". Therefore, on some CPUs, such
- * as Alpha, "y" could be set to 3 and "x" to 0. Use rmb()
- * in cases like this where there are no data dependencies.

-/* Tensilica's xt-xcc compiler is much more agressive at code
- * optimization than gcc. Multiple __asm__ statements are
- * insufficient for xt-xcc because subsequent optimization passes
- * (beyond the front-end that knows of __asm__ statements and other
- * such GNU Extensions to C) can modify the register selection for
- * containment of C variables.
- *
- * xt-xcc cannot modify the contents of a single __asm__ statement, so
- * we create single-asm versions of the syscall macros that are
- * suitable and optimal for both xt-xcc and gcc.
- *
- * Linux takes system-call arguments in registers. The following
- * design is optimized for user-land apps (e.g., glibc) which
- * typically have a function wrapper around the "syscall" assembly
- * instruction. It satisfies the Xtensa ABI while minizing argument
- * shifting.
- *
- * The Xtensa ABI and software conventions require the system-call
- * number in a2. If an argument exists in a2, we move it to the next
- * available register. Note that for improved efficiency, we do NOT
- * shift all parameters down one register to maintain the original
- * order.
- *
- * At best case (zero arguments), we just write the syscall number to
- * a2. At worst case (1 to 6 arguments), we move the argument in a2
- * to the next available register, then write the syscall number to
- * a2.
- *
- * For clarity, the following truth table enumerates all possibilities.
- *
- * arguments syscall number arg0, arg1, arg2, arg3, arg4, arg5

- * The following functions <func> are defined,
- * and apply only to the specified cache (I or D):
- *
- * reset
- * Resets the cache.
- *
- * sync
- * Makes sure any previous cache instructions have been completed;
- * ie. makes sure any previous cache control operations
- * have had full effect and been synchronized to memory.
- * Eg. any invalidate completed [so as not to generate a hit],
- * any writebacks or other pipelined writes written to memory, etc.
- *
- * invalidate_line (single cache line)
- * invalidate_region (specified memory range)
- * invalidate_all (entire cache)
- * Invalidates all cache entries that cache
- * data from the specified memory range.
- * NOTE: locked entries are not invalidated.
- *
- * writeback_line (single cache line)
- * writeback_region (specified memory range)
- * writeback_all (entire cache)
- * Writes back to memory all dirty cache entries
- * that cache data from the specified memory range,
- * and marks these entries as clean.
- * NOTE: on some future implementations, this might
- * also invalidate.
- * NOTE: locked entries are written back, but never invalidated.
- * NOTE: instruction caches never implement writeback.
- *
- * writeback_inv_line (single cache line)
- * writeback_inv_region (specified memory range)
- * writeback_inv_all (entire cache)
- * Writes back to memory all dirty cache entries
- * that cache data from the specified memory range,
- * and invalidates these entries (including all clean
- * cache entries that cache data from that range).
- * NOTE: locked entries are written back but not invalidated.
- * NOTE: instruction caches never implement writeback.
- *
- * lock_line (single cache line)
- * lock_region (specified memory range)
- * Prefetch and lock the specified memory range into cache.
- * NOTE: if any part of the specified memory range cannot
- * be locked, a ??? exception occurs. These macros don't
- * do anything special (yet anyway) to handle this situation.
- *
- * unlock_line (single cache line)
- * unlock_region (specified memory range)

- * The following macros assume the following cache size/parameter limits
- * in the current Xtensa core implementation:
- * cache size: 1024 bytes minimum
- * line size: 16 - 64 bytes
- * way count: 1 - 4
- *
- * Minimum entries per way (ie. per associativity) = 1024 / 64 / 4 = 4
- * Hence the assumption that each loop can execute four cache instructions.
- *
- * Correspondingly, the offset range of instructions is assumed able to cover
- * four lines, ie. offsets {0,1,2,3} * line_size are assumed valid for
- * both hit and indexed cache instructions. Ie. these offsets are all
- * valid: 0, 16, 32, 48, 64, 96, 128, 192 (for line sizes 16, 32, 64).
- * This is true of all original cache instructions
- * (dhi, ihi, dhwb, dhwbi, dii, iii) which have offsets
- * of 0 to 1020 in multiples of 4 (ie. 8 bits shifted by 2).
- * This is also true of subsequent cache instructions
- * (dhu, ihu, diu, iiu, diwb, diwbi, dpfl, ipfl) which have offsets
- * of 0 to 240 in multiples of 16 (ie. 4 bits shifted by 4).
- *
- * (Maximum cache size, currently 32k, doesn't affect the following macros.
- * Cache ways > MMU min page size cause aliasing but that's another matter.)

- * Works even when changing one's own code's attributes.

- ----------------------------------------------------------------------*/
-
-/*
- * General notes on MMU parameters.
- *
- * Terminology:
- * ASID = address-space ID (acts as an "extension" of virtual addresses)
- * VPN = virtual page number
- * PPN = physical page number
- * CA = encoded cache attribute (access modes)
- * TLB = translation look-aside buffer (term is stretched somewhat here)
- * I = instruction (fetch accesses)
- * D = data (load and store accesses)
- * way = each TLB (ITLB and DTLB) consists of a number of "ways"
- * that simultaneously match the virtual address of an access;
- * a TLB successfully translates a virtual address if exactly
- * one way matches the vaddr; if none match, it is a miss;
- * if multiple match, one gets a "multihit" exception;
- * each way can be independently configured in terms of number of
- * entries, page sizes, which fields are writable or constant, etc.
- * set = group of contiguous ways with exactly identical parameters
- * ARF = auto-refill; hardware services a 1st-level miss by loading a PTE
- * from the page table and storing it in one of the auto-refill ways;
- * if this PTE load also misses, a miss exception is posted for s/w.
- * min-wired = a "min-wired" way can be used to map a single (minimum-sized)
- * page arbitrarily under program control; it has a single entry,
- * is non-auto-refill (some other way(s) must be auto-refill),
- * all its fields (VPN, PPN, ASID, CA) are all writable, and it
- * supports the XCHAL_MMU_MIN_PTE_PAGE_SIZE page size (a current
- * restriction is that this be the only page size it supports).
- *
- * TLB way entries are virtually indexed.
- * TLB ways that support multiple page sizes:
- * - must have all writable VPN and PPN fields;
- * - can only use one page size at any given time (eg. setup at startup),
- * selected by the respective ITLBCFG or DTLBCFG special register,
- * whose bits n*4+3 .. n*4 index the list of page sizes for way n
- * (XCHAL_xTLB_SETm_PAGESZ_LOG2_LIST for set m corresponding to way n);
- * this list may be sparse for auto-refill ways because auto-refill
- * ways have independent lists of supported page sizes sharing a
- * common encoding with PTE entries; the encoding is the index into
- * this list; unsupported sizes for a given way are zero in the list;
- * selecting unsupported sizes results in undefined hardware behaviour;
- * - is only possible for ways 0 thru 7 (due to ITLBCFG/DTLBCFG definition).

- * find_ms_setbit
- *
- * This macro finds the most significant bit that is set in <as>
- * and return its index + <base> in <ad>, or <base> - 1 if <as> is zero.
- * The index counts starting at zero for the lsbit, so the return
- * value ranges from <base>-1 (no bit set) to <base>+31 (msbit set).
- *
- * Parameters:
- * <ad> destination address register (any register)
- * <as> source address register
- * <at> temporary address register (must be different than <as>)
- * <base> constant value added to result (usually 0 or 1)
- * On entry:
- * <ad> = undefined if different than <as>
- * <as> = value whose most significant set bit is to be found
- * <at> = undefined
- * no other registers are used by this macro.
- * On exit:
- * <ad> = <base> + index of msbit set in original <as>,
- * = <base> - 1 if original <as> was zero.
- * <as> clobbered (if not <ad>)
- * <at> clobbered (if not <ad>)
- * Example:

- * floop, floopnez, floopgtz, floopend
- *
- * These macros are used for fast inner loops that
- * work whether or not the Loops options is configured.
- * If the Loops option is configured, they simply use
- * the zero-overhead LOOP instructions; otherwise
- * they use explicit decrement and branch instructions.
- *
- * They are used in pairs, with floop, floopnez or floopgtz
- * at the beginning of the loop, and floopend at the end.
- *
- * Each pair of loop macro calls must be given the loop count
- * address register and a unique label for that loop.
- *
- * Example:
- *
- * movi a3, 16 // loop 16 times
- * floop a3, myloop1
- * :
- * bnez a7, end1 // exit loop if a7 != 0
- * :
- * floopend a3, myloop1
- * end1:
- *
- * Like the LOOP instructions, these macros cannot be
- * nested, must include at least one instruction,
- * cannot call functions inside the loop, etc.
- * The loop can be exited by jumping to the instruction
- * following floopend (or elsewhere outside the loop),
- * or continued by jumping to a NOP instruction placed
- * immediately before floopend.
- *
- * Unlike LOOP instructions, the register passed to floop*
- * cannot be used inside the loop, because it is used as
- * the loop counter if the Loops option is not configured.
- * And its value is undefined after exiting the loop.
- * And because the loop counter register is active inside
- * the loop, you can't easily use this construct to loop
- * across a register file using ROTW as you might with LOOP
- * instructions, unless you copy the loop register along.

- * window_spill{4,8,12}
- *
- * These macros spill callers' register windows to the stack.
- * They work for both privileged and non-privileged tasks.
- * Must be called from a windowed ABI context, eg. within
- * a windowed ABI function (ie. valid stack frame, window
- * exceptions enabled, not in exception mode, etc).
- *
- * This macro requires a single invocation of the window_spill_common
- * macro in the same assembly unit and section.
- *
- * Note that using window_spill{4,8,12} macros is more efficient
- * than calling a function implemented using window_spill_function,
- * because the latter needs extra code to figure out the size of
- * the call to the spilling function.
- *
- * Example usage:
- *
- * .text
- * .align 4
- * .global some_function
- * .type some_function,@function
- * some_function:
- * entry a1, 16
- * :
- * :
- *
- * window_spill4 // spill windows of some_function's callers; preserves a0..a3 only;
- * // to use window_spill{8,12} in this example function we'd have
- * // to increase space allocated by the entry instruction, because
- * // 16 bytes only allows call4; 32 or 48 bytes (+locals) are needed
- * // for call8/window_spill8 or call12/window_spill12 respectively.
- * :
- *
- * retw
- *
- * window_spill_common // instantiates code used by window_spill4
- *
- *
- * On entry:
- * none (if window_spill4)
- * stack frame has enough space allocated for call8 (if window_spill8)
- * stack frame has enough space allocated for call12 (if window_spill12)
- * On exit:
- * a4..a15 clobbered (if window_spill4)
- * a8..a15 clobbered (if window_spill8)
- * a12..a15 clobbered (if window_spill12)

- *
- * Release MAJOR MINOR Comment
- * ======= ===== ===== =======
- * T1015.n n/a n/a (HAL not yet available)
- * T1020.{0,1,2} 0 1 (HAL beta)
- * T1020.{3,4} 0 2 First release.
- * T1020.n (n>4) 0 2 or >3 (TBD)
- * T1030.0 0 1 (HAL beta)
- * T1030.{1,2} 0 3 Equivalent to first release.
- * T1030.n (n>=3) 0 >= 3 (TBD)
- * T1040.n 1040 n Full CHAL available from T1040.2
- * T1050.n 1050 n Current release.
- *
- *
- * Note: there is a distinction between the software release with
- * which something is compiled (accessible using XTHAL_RELEASE_* macros)
- * and the software release with which the HAL library was compiled
- * (accessible using Xthal_release_* global variables). This
- * distinction is particularly relevant for vendors that distribute
- * configuration-independent binaries (eg. an OS), where their customer
- * might link it with a HAL of a different Xtensa software release.
- * In this case, it may be appropriate for the OS to verify at run-time
- * whether XTHAL_RELEASE_* and Xthal_release_* are compatible.
- * [Guidelines as to which release is compatible with which are not
- * currently provided explicitly, but might be inferred from reading
- * OSKit documentation for all releases -- compatibility is also highly
- * dependent on which HAL features are used. Each release is usually
- * backward compatible, with very few exceptions if any.]
- *
- * Notes:
- * Tornado 2.0 supported in T1020.3+, T1030.1+, and T1040.{0,1} only.
- * Tornado 2.0.2 supported in T1040.2+, and T1050.
- * Compile-time HAL port of NucleusPlus supported by T1040.2+ and T1050.

- *
- * These services behave largely as if they had been invoked

- * (eg. files accessed are those of the simulator host).
- * However, these SIMCALLs model a virtual operating system
- * so that various definitions, bit assignments etc

- * of the host operating system used to run the simulation.
- * Rather these definitions are specific to the Xtensa ISS.
- * This way Xtensa ISA code written to use these SIMCALLs
- * can (in principle) be simulated on any host.
- *
- * Up to 6 parameters are passed in registers a3 to a8
- * (note the 6th parameter isn't passed on the stack,
- * unlike windowed function calling conventions).
- * The return value is in a2. A negative value in the

- * Device addresses.

- * Note: for endianness-independence, use 32-bit loads and stores for all
- * register accesses to Ethernet, DUART and LED devices. Undefined bits
- * may need to be masked out if needed when reading if the actual register
- * size is smaller than 32 bits.
- *
- * Note: XT2000 bus byte lanes are defined in terms of msbyte and lsbyte
- * relative to the processor. So 32-bit registers are accessed consistently
- * from both big and little endian processors. However, this means byte
- * sequences are not consistent between big and little endian processors.
- * This is fine for RAM, and for ROM if ROM is created for a specific
- * processor (and thus has correct byte sequences). However this may be
- * unexpected for Flash, which might contain a file-system that one wants
- * to use for multiple processor configurations (eg. the Flash might contain
- * the Ethernet card's address, endianness-independent application data, etc).
- * That is, byte sequences written in Flash by a core of a given endianness
- * will be byte-swapped when seen by a core of the other endianness.
- * Someone implementing an endianness-independent Flash file system will
- * likely handle this byte-swapping issue in the Flash driver software.

+/* Comment by Rik:
+ *
+ * For some background on GF(2^128) see for example: http://-
+ * csrc.nist.gov/CryptoToolkit/modes/proposedmodes/gcm/gcm-revised-spec.pdf
+ *
+ * The elements of GF(2^128) := GF(2)[X]/(X^128-X^7-X^2-X^1-1) can
+ * be mapped to computer memory in a variety of ways. Let's examine
+ * three common cases.
+ *
+ * Take a look at the 16 binary octets below in memory order. The msb's
+ * are left and the lsb's are right. char b[16] is an array and b[0] is
+ * the first octet.
+ *
+ * 80000000 00000000 00000000 00000000 .... 00000000 00000000 00000000
+ * b[0] b[1] b[2] b[3] b[13] b[14] b[15]
+ *
+ * Every bit is a coefficient of some power of X. We can store the bits
+ * in every byte in little-endian order and the bytes themselves also in
+ * little endian order. I will call this lle (little-little-endian).
+ * The above buffer represents the polynomial 1, and X^7+X^2+X^1+1 looks
+ * like 11100001 00000000 .... 00000000 = { 0xE1, 0x00, }.
+ * This format was originally implemented in gf128mul and is used
+ * in GCM (Galois/Counter mode) and in ABL (Arbitrary Block Length).
+ *
+ * Another convention says: store the bits in bigendian order and the
+ * bytes also. This is bbe (big-big-endian). Now the buffer above
+ * represents X^127. X^7+X^2+X^1+1 looks like 00000000 .... 10000111,
+ * b[15] = 0x87 and the rest is 0. LRW uses this convention and bbe
+ * is partly implemented.
+ *
+ * Both of the above formats are easy to implement on big-endian
+ * machines.
+ *
+ * EME (which is patent encumbered) uses the ble format (bits are stored
+ * in big endian order and the bytes in little endian). The above buffer
+ * represents X^7 in this case and the primitive polynomial is b[0] = 0x87.
+ *
+ * The common machine word-size is smaller than 128 bits, so to make
+ * an efficient implementation we must split into machine word sizes.
+ * This file uses one 32bit for the moment. Machine endianness comes into
+ * play. The lle format in relation to machine endianness is discussed
+ * below by the original author of gf128mul Dr Brian Gladman.
+ *
+ * Let's look at the bbe and ble format on a little endian machine.
+ *
+ * bbe on a little endian machine u32 x[4]:
+ *
+ * MS x[0] LS MS x[1] LS
+ * ms ls ms ls ms ls ms ls ms ls ms ls ms ls ms ls
+ * 103..96 111.104 119.112 127.120 71...64 79...72 87...80 95...88
+ *
+ * MS x[2] LS MS x[3] LS
+ * ms ls ms ls ms ls ms ls ms ls ms ls ms ls ms ls
+ * 39...32 47...40 55...48 63...56 07...00 15...08 23...16 31...24
+ *
+ * ble on a little endian machine
+ *
+ * MS x[0] LS MS x[1] LS
+ * ms ls ms ls ms ls ms ls ms ls ms ls ms ls ms ls
+ * 31...24 23...16 15...08 07...00 63...56 55...48 47...40 39...32
+ *
+ * MS x[2] LS MS x[3] LS
+ * ms ls ms ls ms ls ms ls ms ls ms ls ms ls ms ls
+ * 95...88 87...80 79...72 71...64 127.120 199.112 111.104 103..96
+ *
+ * Multiplications in GF(2^128) are mostly bit-shifts, so you see why
+ * ble (and lbe also) are easier to implement on a little-endian
+ * machine than on a big-endian machine. The converse holds for bbe
+ * and lle.
+ *
+ * Note: to have good alignment, it seems to me that it is sufficient
+ * to keep elements of GF(2^128) in type u64[2]. On 32-bit wordsize
+ * machines this will automatically aligned to wordsize and on a 64-bit
+ * machine also.
+ */
+/* Multiply a GF128 field element by x. Field elements are held in arrays
+ of bytes in which field bits 8n..8n + 7 are held in byte[n], with lower
+ indexed bits placed in the more numerically significant bit positions
+ within bytes.
+
+ On little endian machines the bit indexes translate into the bit
+ positions within four 32-bit words in the following way
+
+ MS x[0] LS MS x[1] LS
+ ms ls ms ls ms ls ms ls ms ls ms ls ms ls ms ls
+ 24...31 16...23 08...15 00...07 56...63 48...55 40...47 32...39

+ MS x[2] LS MS x[3] LS
+ ms ls ms ls ms ls ms ls ms ls ms ls ms ls ms ls

+ * We cache key information from each zonelist for smaller cache
+ * footprint when scanning for free pages in get_page_from_freelist().
+ *
+ * 1) The BITMAP fullzones tracks which zones in a zonelist have come
+ * up short of free memory since the last time (last_fullzone_zap)
+ * we zero'd fullzones.
+ * 2) The array z_to_n[] maps each zone in the zonelist to its node
+ * id, so that we can efficiently evaluate whether that node is
+ * set in the current tasks mems_allowed.
+ *
+ * Both fullzones and z_to_n[] are one-to-one with the zonelist,
+ * indexed by a zones offset in the zonelist zones[] array.
+ *
+ * The get_page_from_freelist() routine does two scans. During the
+ * first scan, we skip zones whose corresponding bit in 'fullzones'
+ * is set or whose corresponding node in current->mems_allowed (which
+ * comes from cpusets) is not set. During the second scan, we bypass
+ * this zonelist_cache, to ensure we look methodically at each zone.
+ *
+ * Once per second, we zero out (zap) fullzones, forcing us to
+ * reconsider nodes that might have regained more free memory.
+ * The field last_full_zap is the time we last zapped fullzones.
+ *
+ * This mechanism reduces the amount of time we waste repeatedly
+ * reexaming zones for free memory when they just came up low on
+ * memory momentarilly ago.
+ *
+ * The zonelist_cache struct members logically belong in struct
+ * zonelist. However, the mempolicy zonelists constructed for
+ * MPOL_BIND are intentionally variable length (and usually much
+ * shorter). A general purpose mechanism for handling structs with
+ * multiple variable length members is more mechanism than we want
+ * here. We resort to some special case hackery instead.
+ *
+ * The MPOL_BIND zonelists don't need this zonelist_cache (in good
+ * part because they are shorter), so we put the fixed length stuff
+ * at the front of the zonelist struct, ending in a variable length
+ * zones[], as is needed by MPOL_BIND.
+ *
+ * Then we put the optional zonelist cache on the end of the zonelist
+ * struct. This optional stuff is found by a 'zlcache_ptr' pointer in
+ * the fixed length portion at the front of the struct. This pointer
+ * both enables us to find the zonelist cache, and in the case of
+ * MPOL_BIND zonelists, (which will just set the zlcache_ptr to NULL)
+ * to know that the zonelist cache is not there.
+ *
+ * The end result is that struct zonelists come in two flavors:
+ * 1) The full, fixed length version, shown below, and
+ * 2) The custom zonelists for MPOL_BIND.
+ * The custom MPOL_BIND zonelists have a NULL zlcache_ptr and no zlcache.
+ *
+ * Even though there may be multiple CPU cores on a node modifying
+ * fullzones or last_full_zap in the same zonelist_cache at the same
+ * time, we don't lock it. This is just hint data - if it is wrong now
+ * and then, the allocator will still function, perhaps a bit slower.

+ * This source code is licensed under General Public License version 2.

+ *
+ * This library is based on H.225 version 4, H.235 version 2 and H.245

+ * Features:
+ *
+ * 1. Small. The total size of code plus data is less than 20 KB (IA32).
+ * 2. Fast. Decoding Netmeeting's Setup signal 1 million times on a PIII 866
+ * takes only 3.9 seconds.
+ * 3. No memory allocation. It uses a static object. No need to initialize or
+ * cleanup.
+ * 4. Thread safe.
+ * 5. Support embedded architectures that has no misaligned memory access
+ * support.
+ *
+ * Limitations:
+ *
+ * 1. At most 30 faststart entries. Actually this is limited by ethernet's MTU.
+ * If a Setup signal contains more than 30 faststart, the packet size will
+ * very likely exceed the MTU size, then the TPKT will be fragmented. I
+ * don't know how to handle this in a Netfilter module. Anybody can help?
+ * Although I think 30 is enough for most of the cases.
+ * 2. IPv4 addresses only.

- * ip_conntrack_helper_h323_asn1.h - BER and PER decoding library for H.323
- * conntrack/NAT module.
- *
- * Copyright (c) 2006 by Jing Min Zhao <zhaojingmin@users.sourceforge.net>
- *
- * This source code is licensed under General Public License version 2.
- *
- *
- * This library is based on H.225 version 4, H.235 version 2 and H.245
- * version 7. It is extremely optimized to decode only the absolutely
- * necessary objects in a signal for Linux kernel NAT module use, so don't
- * expect it to be a full ASN.1 library.
- *
- * Features:
- *
- * 1. Small. The total size of code plus data is less than 20 KB (IA32).
- * 2. Fast. Decoding Netmeeting's Setup signal 1 million times on a PIII 866
- * takes only 3.9 seconds.
- * 3. No memory allocation. It uses a static object. No need to initialize or
- * cleanup.
- * 4. Thread safe.
- * 5. Support embedded architectures that has no misaligned memory access
- * support.
- *
- * Limitations:
- *
- * 1. At most 30 faststart entries. Actually this is limited by ethernet's MTU.
- * If a Setup signal contains more than 30 faststart, the packet size will
- * very likely exceed the MTU size, then the TPKT will be fragmented. I
- * don't know how to handle this in a Netfilter module. Anybody can help?
- * Although I think 30 is enough for most of the cases.
- * 2. IPv4 addresses only.

+ * Radix-tree synchronization
+ *
+ * The radix-tree API requires that users provide all synchronisation (with
+ * specific exceptions, noted below).
+ *
+ * Synchronization of access to the data items being stored in the tree, and
+ * management of their lifetimes must be completely managed by API users.
+ *
+ * For API usage, in general,
+ * - any function _modifying_ the the tree or tags (inserting or deleting
+ * items, setting or clearing tags must exclude other modifications, and
+ * exclude any functions reading the tree.
+ * - any function _reading_ the the tree or tags (looking up items or tags,
+ * gang lookups) must exclude modifications to the tree, but may occur
+ * concurrently with other readers.
+ *
+ * The notable exceptions to this rule are the following functions:
+ * radix_tree_lookup
+ * radix_tree_tag_get
+ * radix_tree_gang_lookup
+ * radix_tree_gang_lookup_tag
+ * radix_tree_tagged
+ *
+ * The first 4 functions are able to be called locklessly, using RCU. The
+ * caller must ensure calls to these functions are made within rcu_read_lock()
+ * regions. Other readers (lock-free or otherwise) and modifications may be
+ * running concurrently.
+ *
+ * It is still required that the caller manage the synchronization and lifetimes
+ * of the items. So if RCU lock-free lookups are used, typically this would mean
+ * that the items have their own locks, or are amenable to lock-free access; and
+ * that the items are freed by RCU (or only freed after having been deleted from
+ * the radix tree *and* a synchronize_rcu() grace period).
+ *
+ * (Note, rcu_assign_pointer and rcu_dereference are not needed to control
+ * access to data items when inserting into or looking up from the radix tree)
+ *
+ * radix_tree_tagged is able to be called without locking or RCU.

+ Generic support for BUG()
+
+ This respects the following config options:
+
+ CONFIG_BUG - emit BUG traps. Nothing happens without this.
+ CONFIG_GENERIC_BUG - enable this code.
+ CONFIG_DEBUG_BUGVERBOSE - emit full file+line information for each BUG
+
+ CONFIG_BUG and CONFIG_DEBUG_BUGVERBOSE are potentially user-settable
+ (though they're generally always on).
+
+ CONFIG_GENERIC_BUG is set by each architecture using this code.
+
+ To use this, your architecture must:
+
+ 1. Set up the config options:
+ - Enable CONFIG_GENERIC_BUG if CONFIG_BUG
+
+ 2. Implement BUG (and optionally BUG_ON, WARN, WARN_ON)
+ - Define HAVE_ARCH_BUG
+ - Implement BUG() to generate a faulting instruction
+ - NOTE: struct bug_entry does not have "file" or "line" entries
+ when CONFIG_DEBUG_BUGVERBOSE is not enabled, so you must generate
+ the values accordingly.
+
+ 3. Implement the trap
+ - In the illegal instruction trap handler (typically), verify
+ that the fault was in kernel mode, and call report_bug()
+ - report_bug() will return whether it was a false alarm, a warning,
+ or an actual bug.
+ - You must implement the is_valid_bugaddr(bugaddr) callback which
+ returns true if the eip is a real kernel address, and it points
+ to the expected BUG trap instruction.

- The Frame Diverter allows you to divert packets from the

- This is very useful when you don't want to change your router's
- config (or if you simply don't have access to it).

- The other possible usages of diverting Ethernet Frames are

- - reroute smtp traffic to another interface
- - traffic-shape certain network streams
- - transparently proxy smtp connections
- - etc...

+ Use higher lower bound for nofeedback timer expiration.
+
+ The TFRC nofeedback timer normally expires after the maximum of 4
+ RTTs and twice the current send interval (RFC 3448, 4.3). On LANs
+ with a small RTT this can mean a high processing load and reduced
+ performance, since then the nofeedback timer is triggered very
+ frequently.
+
+ This option enables to set a higher lower bound for the nofeedback
+ value. Values in units of milliseconds can be set here.
+
+ A value of 0 disables this feature by enforcing the value specified
+ in RFC 3448. The following values have been suggested as bounds for
+ experimental use:
+ * 16-20ms to match the typical multimedia inter-frame interval
+ * 100ms as a reasonable compromise [default]
+ * 1000ms corresponds to the lower TCP RTO bound (RFC 2988, 2.4)
+
+ The default of 100ms is a compromise between a large value for
+ efficient DCCP implementations, and a small value to avoid disrupting
+ the network in times of congestion.
+
+ The purpose of the nofeedback timer is to slow DCCP down when there
+ is serious network congestion: experimenting with larger values should
+ therefore not be performed on WANs.

+ equation from [RFC 3448, sec. 3.1]:
+
+ s
+ X_calc = --------------------------------------------------------------
+ R * sqrt(2*b*p/3) + (3 * t_RTO * sqrt(3*b*p/8) * (p + 32*p^3))
+
+ Where:
+ X is the transmit rate in bytes/second
+ s is the packet size in bytes
+ R is the round trip time in seconds
+ p is the loss event rate, between 0 and 1.0, of the number of loss
+ events as a fraction of the number of packets transmitted
+ t_RTO is the TCP retransmission timeout value in seconds
+ b is the number of packets acknowledged by a single TCP ACK
+
+ We can assume that b = 1 and t_RTO is 4 * R. The equation now becomes:
+
+ s
+ X_calc = -------------------------------------------------------

+
+ which we can break down into:
+
+ s
+ X_calc = ---------
+ R * f(p)
+
+ where f(p) is given for 0 < p <= 1 by:
+
+ f(p) = sqrt(2*p/3) + 12 * sqrt(3*p/8) * (p + 32*p^3)
+
+ Since this is kernel code, floating-point arithmetic is avoided in favour of
+ integer arithmetic. This means that nearly all fractional parameters are
+ scaled by 1000000:
+ * the parameters p and R
+ * the return result f(p)
+ The lookup table therefore actually tabulates the following function g(q):
+
+ g(q) = 1000000 * f(q/1000000)
+
+ Hence, when p <= 1, q must be less than or equal to 1000000. To achieve finer
+ granularity for the practically more relevant case of small values of p (up to
+ 5%), the second column is used; the first one ranges up to 100%. This split
+ corresponds to the value of q = TFRC_CALC_X_SPLIT. At the same time this also
+ determines the smallest resolution possible with this lookup table:
+
+ TFRC_SMALLEST_P = TFRC_CALC_X_SPLIT / TFRC_CALC_X_ARRSIZE
+
+ The entire table is generated by:
+ for(i=0; i < TFRC_CALC_X_ARRSIZE; i++) {
+ lookup[i][0] = g((i+1) * 1000000/TFRC_CALC_X_ARRSIZE);
+ lookup[i][1] = g((i+1) * TFRC_CALC_X_SPLIT/TFRC_CALC_X_ARRSIZE);
+ }
+
+ With the given configuration, we have, with M = TFRC_CALC_X_ARRSIZE-1,
+ lookup[0][0] = g(1000000/(M+1)) = 1000000 * f(0.2%)
+ lookup[M][0] = g(1000000) = 1000000 * f(100%)
+ lookup[0][1] = g(TFRC_SMALLEST_P) = 1000000 * f(0.01%)
+ lookup[M][1] = g(TFRC_CALC_X_SPLIT) = 1000000 * f(5%)
+
+ In summary, the two columns represent f(p) for the following ranges:
+ * The first column is for 0.002 <= p <= 1.0
+ * The second column is for 0.0001 <= p <= 0.05
+ Where the columns overlap, the second (finer-grained) is given preference,
+ i.e. the first column is used only for p >= 0.05.

- * Hervé Eychenne <eychenne@info.enserb.u-bordeaux.fr>
- * Rusty Russell <rusty@rustcorp.com.au>
- *
- * The general idea is to create a hash table for every dstip and have a

- * the number of syn packets for each of my internal addresses.
- *
- * Ideally this would just be implemented as a general 'hash' match, which would
- * allow us to attach any iptables target to it's hash buckets. But this is
- * not possible in the current iptables architecture. As always, pkttables for

- test, `cost'.
-
- `prev' tracks the last packet hit: you gain one credit per jiffy.
- If you get credit balance more than this, the extra credit is
- discarded. Every time the match passes, you lose `cost' credits;
- if you don't have that many, the test fails.
-
- See Alexey's formal explanation in net/sched/sch_tbf.c.

+/*
+ * nf_nat_snmp_basic.c
+ *
+ * Basic SNMP Application Layer Gateway
+ *
+ * This IP NAT module is intended for use with SNMP network
+ * discovery and monitoring applications where target networks use
+ * conflicting private address realms.
+ *
+ * Static NAT is used to remap the networks from the view of the network
+ * management system at the IP layer, and this module remaps some application
+ * layer addresses to match.
+ *
+ * The simplest form of ALG is performed, where only tagged IP addresses
+ * are modified. The module does not need to be MIB aware and only scans
+ * messages at the ASN.1/BER level.
+ *
+ * Currently, only SNMPv1 and SNMPv2 are supported.
+ *
+ * More information on ALG and associated issues can be found in
+ * RFC 2962
+ *
+ * The ASB.1/BER parsing code is derived from the gxsnmp package by Gregory
+ * McLean & Jochen Friedrich, stripped down for use in the kernel.

+ * Connection tracking support for PPTP (Point to Point Tunneling Protocol).

+ * working with Microsoft. PPTP is built on top of a modified
+ * version of the Internet Generic Routing Encapsulation Protocol.
+ * GRE is defined in RFC 1701 and RFC 1702. Documentation of

+ *
+ * Development of this code funded by Astaro AG (http://www.astaro.com/)
+ *
+ * Limitations:
+ * - We blindly assume that control connections are always
+ * established in PNS->PAC direction. This is a violation
+ * of RFFC2673
+ * - We can only support one single call within each session
+ * TODO:

+ * ip_conntrack_proto_gre.c - Version 3.0
+ *
+ * Connection tracking protocol helper module for GRE.
+ *
+ * GRE is a generic encapsulation protocol, which is generally not very
+ * suited for NAT, as it has no protocol-specific part as port numbers.
+ *
+ * It has an optional key field, which may help us distinguishing two
+ * connections between the same two hosts.
+ *
+ * GRE is defined in RFC 1701 and RFC 1702, as well as RFC 2784
+ *
+ * PPTP is built on top of a modified version of GRE, and has a mandatory
+ * field called "CallID", which serves us for the same purpose as the key
+ * field in plain GRE.
+ *
+ * Documentation about PPTP can be found in RFC 2637
+ *
+ * (C) 2000-2005 by Harald Welte <laforge@gnumonks.org>
+ *
+ * Development of this code funded by Astaro AG (http://www.astaro.com/)

+ amount of credit `credit' and the most credit you can ever have
+ `credit_cap'. The `peak rate' becomes the cost of passing the
+ test, `cost'.
+
+ `prev' tracks the last packet hit: you gain one credit per jiffy.
+ If you get credit balance more than this, the extra credit is
+ discarded. Every time the match passes, you lose `cost' credits;
+ if you don't have that many, the test fails.
+
+ See Alexey's formal explanation in net/sched/sch_tbf.c.
+
+ To get the maximum range, we multiply by this factor (ie. you get N
+ credits per jiffy). We want to allow a rate as low as 1 per day
+ (slowest userspace tool allows), which means
