+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

-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.

Under each directory you would find an "online" file which is the control
file to logically online/offline a processor.
Q: Does hot-add/hot-remove refer to physical add/remove of cpus?
A: The usage of hot-add/remove may not be very consistently used in the code.
-CONFIG_CPU_HOTPLUG enables logical online/offline capability in the kernel.
+CONFIG_HOTPLUG_CPU enables logical online/offline capability in the kernel.
To support physical addition/removal, one would need some BIOS hooks and
the platform should have something like an attention button in PCI hotplug.
CONFIG_ACPI_HOTPLUG_CPU enables ACPI support for physical add/remove of CPUs.
Q: How do i logically offline a CPU?
A: Do the following.
-#echo 0 > /sys/devices/system/cpu/cpuX/online
+ #echo 0 > /sys/devices/system/cpu/cpuX/online
-once the logical offline is successful, check

Q: Why cant i remove CPU0 on some systems?
A: Some architectures may have some special dependency on a certain CPU.
departure, how to i arrange for proper notification?
A: This is what you would need in your kernel code to receive notifications.
- #include <linux/cpu.h>
- static int __cpuinit foobar_cpu_callback(struct notifier_block *nfb,
+ #include <linux/cpu.h>
+ static int __cpuinit foobar_cpu_callback(struct notifier_block *nfb,
unsigned long action, void *hcpu)
{
unsigned int cpu = (unsigned long)hcpu;
A: Yes, CPU notifiers are called only when new CPUs are on-lined or offlined.
If you need to perform some action for each cpu already in the system, then
- for_each_online_cpu(i) {
+ for_each_online_cpu(i) {
foobar_cpu_callback(&foobar_cpu_notifier, CPU_UP_PREPARE, i);
- foobar_cpu_callback(&foobar-cpu_notifier, CPU_ONLINE, i);

+ }
Q: If i would like to develop cpu hotplug support for a new architecture,
what do i need at a minimum?

+Ext4 Filesystem
+===============
+
+This is a development version of the ext4 filesystem, an advanced level
+of the ext3 filesystem which incorporates scalability and reliability
+enhancements for supporting large filesystems (64 bit) in keeping with
+increasing disk capacities and state-of-the-art feature requirements.
+
+Mailing list: linux-ext4@vger.kernel.org
+
+
+1. Quick usage instructions:
+===========================
+
+ - Grab updated e2fsprogs from
+ ftp://ftp.kernel.org/pub/linux/kernel/people/tytso/e2fsprogs-interim/
+ This is a patchset on top of e2fsprogs-1.39, which can be found at
+ ftp://ftp.kernel.org/pub/linux/kernel/people/tytso/e2fsprogs/
+
+ - It's still mke2fs -j /dev/hda1
+
+ - mount /dev/hda1 /wherever -t ext4dev
+
+ - To enable extents,
+
+ mount /dev/hda1 /wherever -t ext4dev -o extents
+
+ - The filesystem is compatible with the ext3 driver until you add a file
+ which has extents (ie: `mount -o extents', then create a file).
+
+ NOTE: The "extents" mount flag is temporary. It will soon go away and
+ extents will be enabled by the "-o extents" flag to mke2fs or tune2fs
+
+ - When comparing performance with other filesystems, remember that
+ ext3/4 by default offers higher data integrity guarantees than most. So
+ when comparing with a metadata-only journalling filesystem, use `mount -o
+ data=writeback'. And you might as well use `mount -o nobh' too along
+ with it. Making the journal larger than the mke2fs default often helps
+ performance with metadata-intensive workloads.
+
+2. Features
+===========
+
+2.1 Currently available
+
+* ability to use filesystems > 16TB
+* extent format reduces metadata overhead (RAM, IO for access, transactions)
+* extent format more robust in face of on-disk corruption due to magics,
+* internal redunancy in tree
+
+2.1 Previously available, soon to be enabled by default by "mkefs.ext4":
+
+* dir_index and resize inode will be on by default
+* large inodes will be used by default for fast EAs, nsec timestamps, etc
+
+2.2 Candidate features for future inclusion
+
+There are several under discussion, whether they all make it in is
+partly a function of how much time everyone has to work on them:
+
+* improved file allocation (multi-block alloc, delayed alloc; basically done)
+* fix 32000 subdirectory limit (patch exists, needs some e2fsck work)
+* nsec timestamps for mtime, atime, ctime, create time (patch exists,
+ needs some e2fsck work)
+* inode version field on disk (NFSv4, Lustre; prototype exists)
+* reduced mke2fs/e2fsck time via uninitialized groups (prototype exists)
+* journal checksumming for robustness, performance (prototype exists)
+* persistent file preallocation (e.g for streaming media, databases)
+
+Features like metadata checksumming have been discussed and planned for
+a bit but no patches exist yet so I'm not sure they're in the near-term
+roadmap.
+
+The big performance win will come with mballoc and delalloc. CFS has
+been using mballoc for a few years already with Lustre, and IBM + Bull
+did a lot of benchmarking on it. The reason it isn't in the first set of
+patches is partly a manageability issue, and partly because it doesn't
+directly affect the on-disk format (outside of much better allocation)
+so it isn't critical to get into the first round of changes. I believe
+Alex is working on a new set of patches right now.
+
+3. Options
+==========
+
+When mounting an ext4 filesystem, the following option are accepted:
+(*) == default
+
+extents ext4 will use extents to address file data. The
+ file system will no longer be mountable by ext3.
+
+journal=update Update the ext4 file system's journal to the current
+ format.
+
+journal=inum When a journal already exists, this option is ignored.
+ Otherwise, it specifies the number of the inode which
+ will represent the ext4 file system's journal file.
+
+journal_dev=devnum When the external journal device's major/minor numbers
+ have changed, this option allows the user to specify
+ the new journal location. The journal device is
+ identified through its new major/minor numbers encoded
+ in devnum.
+
+noload Don't load the journal on mounting.
+
+data=journal All data are committed into the journal prior to being
+ written into the main file system.
+
+data=ordered (*) All data are forced directly out to the main file
+ system prior to its metadata being committed to the
+ journal.
+
+data=writeback Data ordering is not preserved, data may be written
+ into the main file system after its metadata has been
+ committed to the journal.
+
+commit=nrsec (*) Ext4 can be told to sync all its data and metadata
+ every 'nrsec' seconds. The default value is 5 seconds.
+ This means that if you lose your power, you will lose
+ as much as the latest 5 seconds of work (your
+ filesystem will not be damaged though, thanks to the
+ journaling). This default value (or any low value)
+ will hurt performance, but it's good for data-safety.
+ Setting it to 0 will have the same effect as leaving
+ it at the default (5 seconds).
+ Setting it to very large values will improve
+ performance.
+
+barrier=1 This enables/disables barriers. barrier=0 disables
+ it, barrier=1 enables it.
+
+orlov (*) This enables the new Orlov block allocator. It is
+ enabled by default.
+
+oldalloc This disables the Orlov block allocator and enables
+ the old block allocator. Orlov should have better
+ performance - we'd like to get some feedback if it's
+ the contrary for you.
+
+user_xattr Enables Extended User Attributes. Additionally, you
+ need to have extended attribute support enabled in the
+ kernel configuration (CONFIG_EXT4_FS_XATTR). See the
+ attr(5) manual page and http://acl.bestbits.at/ to
+ learn more about extended attributes.
+
+nouser_xattr Disables Extended User Attributes.
+
+acl Enables POSIX Access Control Lists support.
+ Additionally, you need to have ACL support enabled in
+ the kernel configuration (CONFIG_EXT4_FS_POSIX_ACL).
+ See the acl(5) manual page and http://acl.bestbits.at/
+ for more information.
+
+noacl This option disables POSIX Access Control List
+ support.
+
+reservation
+
+noreservation
+
+bsddf (*) Make 'df' act like BSD.
+minixdf Make 'df' act like Minix.
+
+check=none Don't do extra checking of bitmaps on mount.
+nocheck
+
+debug Extra debugging information is sent to syslog.
+
+errors=remount-ro(*) Remount the filesystem read-only on an error.
+errors=continue Keep going on a filesystem error.
+errors=panic Panic and halt the machine if an error occurs.
+
+grpid Give objects the same group ID as their creator.
+bsdgroups
+
+nogrpid (*) New objects have the group ID of their creator.
+sysvgroups
+
+resgid=n The group ID which may use the reserved blocks.
+
+resuid=n The user ID which may use the reserved blocks.
+
+sb=n Use alternate superblock at this location.
+
+quota
+noquota
+grpquota
+usrquota
+
+bh (*) ext4 associates buffer heads to data pages to
+nobh (a) cache disk block mapping information
+ (b) link pages into transaction to provide
+ ordering guarantees.
+ "bh" option forces use of buffer heads.
+ "nobh" option tries to avoid associating buffer
+ heads (supported only for "writeback" mode).
+
+
+Data Mode
+---------
+There are 3 different data modes:
+
+* writeback mode
+In data=writeback mode, ext4 does not journal data at all. This mode provides
+a similar level of journaling as that of XFS, JFS, and ReiserFS in its default
+mode - metadata journaling. A crash+recovery can cause incorrect data to
+appear in files which were written shortly before the crash. This mode will
+typically provide the best ext4 performance.
+
+* ordered mode
+In data=ordered mode, ext4 only officially journals metadata, but it logically
+groups metadata and data blocks into a single unit called a transaction. When
+it's time to write the new metadata out to disk, the associated data blocks
+are written first. In general, this mode performs slightly slower than
+writeback but significantly faster than journal mode.
+
+* journal mode
+data=journal mode provides full data and metadata journaling. All new data is
+written to the journal first, and then to its final location.
+In the event of a crash, the journal can be replayed, bringing both data and
+metadata into a consistent state. This mode is the slowest except when data
+needs to be read from and written to disk at the same time where it
+outperforms all others modes.

-ACPI / IBM ThinkPad Laptop Extras). The rest of this section describes
-how to install this driver when downloaded from the web site.
-
-First, you need to get a kernel with ACPI support up and running.
-Please refer to http://acpi.sourceforge.net/ for help with this
-step. How successful you will be depends a lot on you ThinkPad model,
-the kernel you are using and any additional patches applied. The
-kernel provided with your distribution may not be good enough. I
-needed to compile a 2.6.7 kernel with the 20040715 ACPI patch to get
-ACPI working reliably on my ThinkPad X40. Old ThinkPad models may not
-be supported at all.
-
-Assuming you have the basic ACPI support working (e.g. you can see the
-/proc/acpi directory), follow the following steps to install this
-driver:
-
- - unpack the archive:
-
- tar xzvf ibm-acpi-x.y.tar.gz; cd ibm-acpi-x.y
-
- - compile the driver:
-
- make
-
- - install the module in your kernel modules directory:
-
- make install
-
- - load the module:
-
- modprobe ibm_acpi
-
-After loading the module, check the "dmesg" output for any error messages.

Features
--------
with this, do send me your results (including some complete dumps with
a description of the conditions when they were taken.)
-EXPERIMENTAL: LCD brightness control -- /proc/acpi/ibm/brightness
------------------------------------------------------------------
-
-This feature is marked EXPERIMENTAL because the implementation
-directly accesses hardware registers and may not work as expected. USE
-WITH CAUTION! To use this feature, you need to supply the
-experimental=1 parameter when loading the module.
+LCD brightness control -- /proc/acpi/ibm/brightness
+---------------------------------------------------
This feature allows software control of the LCD brightness on ThinkPad
models which don't have a hardware brightness slider. The available
The <level> number range is 0 to 7, although not all of them may be
distinct. The current brightness level is shown in the file.
-EXPERIMENTAL: Volume control -- /proc/acpi/ibm/volume
------------------------------------------------------
-
-This feature is marked EXPERIMENTAL because the implementation
-directly accesses hardware registers and may not work as expected. USE
-WITH CAUTION! To use this feature, you need to supply the
-experimental=1 parameter when loading the module.
+Volume control -- /proc/acpi/ibm/volume
+---------------------------------------
This feature allows volume control on ThinkPad models which don't have
a hardware volume knob. The available commands are:
echo 'level <level>' > /proc/acpi/ibm/thermal
+EXPERIMENTAL: WAN -- /proc/acpi/ibm/wan
+---------------------------------------
+
+This feature is marked EXPERIMENTAL because the implementation
+directly accesses hardware registers and may not work as expected. USE
+WITH CAUTION! To use this feature, you need to supply the
+experimental=1 parameter when loading the module.
+
+This feature shows the presence and current state of a WAN (Sierra
+Wireless EV-DO) device. If WAN is installed, the following commands can
+be used:
+
+ echo enable > /proc/acpi/ibm/wan
+ echo disable > /proc/acpi/ibm/wan
+
+It was tested on a Lenovo Thinkpad X60. It should probably work on other
+Thinkpad models which come with this module installed.
Multiple Commands, Module Parameters
------------------------------------
This is the very first release of a driver for X-Box gamepads.
Basically, this was hacked away in just a few hours, so don't expect
miracles.
+
In particular, there is currently NO support for the rumble pack.
You won't find many ff-aware linux applications anyway.
-0. Status
----------
+0. Notes
+--------
+
+Driver updated for kernel 2.6.17.11. (Based on a patch for 2.6.11.4.)
-For now, this driver has only been tested on just one Linux-Box.
-This one is running a 2.4.18 kernel with usb-uhci on an amd athlon 600.
+The number of buttons/axes reported varies based on 3 things:
+- if you are using a known controller
+- if you are using a known dance pad
+- if using an unknown device (one not listed below), what you set in the
+ module configuration for "Map D-PAD to buttons rather than axes for unknown
+ pads" (module option dpad_to_buttons)
-The jstest-program from joystick-1.2.15 (jstest-version 2.1.0) reports
-8 axes and 10 buttons.
+If you set dpad_to_buttons to 0 and you are using an unknown device (one
+not listed below), the driver will map the directional pad to axes (X/Y),
+if you said N it will map the d-pad to buttons, which is needed for dance
+style games to function correctly. The default is Y.
+
+dpad_to_buttons has no effect for known pads.
+
+0.1 Normal Controllers
+----------------------
+With a normal controller, the directional pad is mapped to its own X/Y axes.
+The jstest-program from joystick-1.2.15 (jstest-version 2.1.0) will report 8
+axes and 10 buttons.
-Alls 8 axes work, though they all have the same range (-32768..32767)
+All 8 axes work, though they all have the same range (-32768..32767)
and the zero-setting is not correct for the triggers (I don't know if that
is some limitation of jstest, since the input device setup should be fine. I
didn't have a look at jstest itself yet).
play first person shooters with a pad. Your mileage may vary.
+0.2 Xbox Dance Pads
+-------------------
+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
+left+right or up+down, making DDR style games unplayable.
+
+Known dance pads automatically map the d-pad to buttons and will work
+correctly out of the box.
+
+If your dance pad is recognized by the driver but is using axes instead
+of buttons, see section 0.3 - Unknown Controllers
+
+I've tested this with Stepmania, and it works quite well.
+
+
+0.3 Unkown Controllers
+----------------------
+If you have an unkown xbox controller, it should work just fine with
+the default settings.
+
+HOWEVER if you have an unknown dance pad not listed below, it will not
+work UNLESS you set "dpad_to_buttons" to 1 in the module configuration.
+
+PLEASE if you have an unkown controller, email Dom <binary1230@yahoo.com> with
+a dump from /proc/bus/usb and a description of the pad (manufacturer, country,
+whether it is a dance pad or normal controller) so that we can add your pad
+to the list of supported devices, ensuring that it will work out of the
+box in the future.
+
+
1. USB adapter
--------------
Before you can actually use the driver, you need to get yourself an
-adapter cable to connect the X-Box controller to your Linux-Box.
+adapter cable to connect the X-Box controller to your Linux-Box. You
+can buy these online fairly cheap, or build your own.
-Such a cable is pretty easy to build. The Controller itself is a USB compound
-device (a hub with three ports for two expansion slots and the controller
-device) with the only difference in a nonstandard connector (5 pins vs. 4 on
-standard USB connector).

+2. Driver Installation
----------------------
Once you have the adapter cable and the controller is connected, you need
to load your USB subsystem and should cat /proc/bus/usb/devices.
There should be an entry like the one at the end [4].
-Currently (as of version 0.0.4), the following three devices are included:
+Currently (as of version 0.0.6), the following devices are included:

InterAct PowerPad Pro (Germany), vendor=0x05fd, product=0x107a
+ RedOctane Xbox Dance Pad (US), vendor=0x0c12, product=0x8809
-If you have another controller that is not listed above and is not recognized
-by the driver, please drop me a line with the appropriate info (that is, include
-the name, vendor and product ID, as well as the country where you bought it;
-sending the whole dump out of /proc/bus/usb/devices along would be even better).
+The driver should work with xbox pads not listed above as well, however
+you will need to do something extra for dance pads to work.
-In theory, the driver should work with other controllers than mine
-(InterAct PowerPad pro, bought in Germany) just fine, but I cannot test this
-for I only have this one controller.
+If you have a controller not listed above, see 0.3 - Unknown Controllers
If you compiled and installed the driver, test the functionality:
> modprobe xpad
> modprobe joydev
> jstest /dev/js0
-There should be a single line showing 18 inputs (8 axes, 10 buttons), and
-it's values should change if you move the sticks and push the buttons.
+If you're using a normal controller, there should be a single line showing
+18 inputs (8 axes, 10 buttons), and its values should change if you move

+show 20 inputs (6 axes, 14 buttons).
-It works? Voila, your done ;)

Usage Notes :
-Prior to call ccw_device_start() the device driver must assure disabled state,
-i.e. the I/O mask value in the PSW must be disabled. This can be accomplished
-by calling local_save_flags( flags). The current PSW flags are preserved and
-can be restored by local_irq_restore( flags) at a later time.
-
-If the device driver violates this rule while running in a uni-processor
-environment an interrupt might be presented prior to the ccw_device_start()
-routine returning to the device driver main path. In this case we will end in a
-deadlock situation as the interrupt handler will try to obtain the irq
-lock the device driver still owns (see below) !

*
* Changed full name of USB-UIRT device to avoid "/" character.
* Added FTDI's alternate PID (0x6006) for FT232/245 devices.
* Added PID for "ELV USB Module UO100" from Stefan Frings.
- *

- *
+ *
* (23/Jun/2003) Ian Abbott
* Reduced flip buffer pushes and corrected a data length test in
* ftdi_read_bulk_callback.
*
* (21/Jun/2003) Erik Nygren
* Added support for Home Electronics Tira-1 IR transceiver using FT232BM chip.
- * See <http://www.home-electro.com/tira1.htm>. Only operates properly
+ * See <http://www.home-electro.com/tira1.htm>. Only operates properly

* Also force the Tira-1 and USB-UIRT to only use their custom baud rates.
*
* (17/Feb/2003) Bill Ryder
* Added write urb buffer pool on a per device basis
* Added more checking for open file on callbacks (fixed OOPS)
- * Added CrystalFontz 632 and 634 PIDs
+ * Added CrystalFontz 632 and 634 PIDs
* (thanx to CrystalFontz for the sample devices - they flushed out

* Fixed FTDI_SIO (the original device) bug
* Fixed some shutdown handling
- *
- *

+ *
+ *
+ *
* (07/Jun/2002) Kuba Ober
* Changed FTDI_SIO_BASE_BAUD_TO_DIVISOR macro into ftdi_baud_to_divisor
* function. It was getting too complex.
*
* (25/Jul/2002) Bill Ryder inserted Dmitri's TIOCMIWAIT patch
* Not tested by me but it doesn't break anything I use.
- *
+ *
* (04/Jan/2002) Kuba Ober
* Implemented 38400 baudrate kludge, where it can be substituted with other
* values. That's the only way to set custom baudrates.
* (the previous version caused panics)
* Removed port iteration code since the device only has one I/O port and it
* was wrong anyway.
- *
+ *
* (31/May/2001) gkh
* Switched from using spinlock to a semaphore, which fixes lots of problems.
*
* Cleaned up comments for 8U232
* Added parity, framing and overrun error handling
* Added receive break handling.
- *
+ *
* (04/08/2001) gb
* Identify version on module load.
- *
+ *
* (18/March/2001) Bill Ryder
* (Not released)
* Added send break handling. (requires kernel patch too)
* Fixed 8U232AM hardware RTS/CTS etc status reporting.
* Added flipbuf fix copied from generic device
- *
+ *
* (12/3/2000) Bill Ryder
* Added support for 8U232AM device.
* Moved PID and VIDs into header file only.
* Cleaned up comments. Removed multiple PID/VID definitions.
* Factorised cts/dtr code
* Made use of __FUNCTION__ in dbg's
- *
+ *
* (11/01/2000) Adam J. Richter
* usb_device_id table support
- *
+ *
* (10/05/2000) gkh
* Fixed bug with urb->dev not being set properly, now that the usb
* core needs it.
- *
+ *
* (09/11/2000) gkh
* Removed DEBUG #ifdefs with call to usb_serial_debug_data
*
* Added module_init and module_exit functions to handle the fact that this
* driver is a loadable module now.
*
- * (04/04/2000) Bill Ryder
+ * (04/04/2000) Bill Ryder
* Fixed bugs in TCGET/TCSET ioctls (by removing them - they are
* handled elsewhere in the tty io driver chain).
*
- * (03/30/2000) Bill Ryder
+ * (03/30/2000) Bill Ryder
* Implemented lots of ioctls
* Fixed a race condition in write
* Changed some dbg's to errs

+ help
+ Ext4dev is a predecessor filesystem of the next generation
+ extended fs ext4, based on ext3 filesystem code. It will be
+ renamed ext4 fs later, once ext4dev is mature and stabilized.
+
+ Unlike the change from ext2 filesystem to ext3 filesystem,
+ the on-disk format of ext4dev is not the same as ext3 any more:
+ it is based on extent maps and it supports 48-bit physical block
+ numbers. These combined on-disk format changes will allow
+ ext4dev/ext4 to handle more than 16 TB filesystem volumes --
+ a hard limit that ext3 cannot overcome without changing the
+ on-disk format.
+
+ Other than extent maps and 48-bit block numbers, ext4dev also is
+ likely to have other new features such as persistent preallocation,
+ high resolution time stamps, and larger file support etc. These
+ features will be added to ext4dev gradually.
+
+ To compile this file system support as a module, choose M here. The
+ module will be called ext4dev. Be aware, however, that the filesystem
+ of your root partition (the one containing the directory /) cannot
+ be compiled as a module, and so this could be dangerous.

+ * Extended attributes are stored directly in inodes (on file systems with
+ * inodes bigger than 128 bytes) and on additional disk blocks. The i_file_acl
+ * field contains the block number if an inode uses an additional block. All
+ * attributes must fit in the inode and one additional block. Blocks that
+ * contain the identical set of attributes may be shared among several inodes.
+ * Identical blocks are detected by keeping a cache of blocks that have
+ * recently been accessed.
+ *
+ * The attributes in inodes and on blocks have a different header; the entries
+ * are stored in the same format:
+ *
+ * +------------------+
+ * | header |
+ * | entry 1 | |
+ * | entry 2 | | growing downwards
+ * | entry 3 | v
+ * | four null bytes |
+ * | . . . |
+ * | value 1 | ^
+ * | value 3 | | growing upwards
+ * | value 2 | |
+ * +------------------+
+ *
+ * The header is followed by multiple entry descriptors. In disk blocks, the
+ * entry descriptors are kept sorted. In inodes, they are unsorted. The
+ * attribute values are aligned to the end of the block in no specific order.
+ *
+ * Locking strategy
+ * ----------------
+ * EXT4_I(inode)->i_file_acl is protected by EXT4_I(inode)->xattr_sem.
+ * EA blocks are only changed if they are exclusive to an inode, so
+ * holding xattr_sem also means that nothing but the EA block's reference
+ * count can change. Multiple writers to the same block are synchronized
+ * by the buffer lock.

+ * Journal revoke routines for the generic filesystem journaling code;
+ * part of the ext2fs journaling system.
+ *
+ * Revoke is the mechanism used to prevent old log records for deleted
+ * metadata from being replayed on top of newer data using the same
+ * blocks. The revoke mechanism is used in two separate places:
+ *
+ * + Commit: during commit we write the entire list of the current
+ * transaction's revoked blocks to the journal
+ *
+ * + Recovery: during recovery we record the transaction ID of all
+ * revoked blocks. If there are multiple revoke records in the log
+ * for a single block, only the last one counts, and if there is a log
+ * entry for a block beyond the last revoke, then that log entry still
+ * gets replayed.
+ *
+ * We can get interactions between revokes and new log data within a
+ * single transaction:
+ *
+ * Block is revoked and then journaled:
+ * The desired end result is the journaling of the new block, so we
+ * cancel the revoke before the transaction commits.
+ *
+ * Block is journaled and then revoked:
+ * The revoke must take precedence over the write of the block, so we
+ * need either to cancel the journal entry or to write the revoke
+ * later in the log than the log block. In this case, we choose the
+ * latter: journaling a block cancels any revoke record for that block
+ * in the current transaction, so any revoke for that block in the
+ * transaction must have happened after the block was journaled and so
+ * the revoke must take precedence.
+ *
+ * Block is revoked and then written as data:
+ * The data write is allowed to succeed, but the revoke is _not_
+ * cancelled. We still need to prevent old log records from
+ * overwriting the new data. We don't even need to clear the revoke
+ * bit here.
+ *
+ * Revoke information on buffers is a tri-state value:
+ *
+ * RevokeValid clear: no cached revoke status, need to look it up
+ * RevokeValid set, Revoked clear:
+ * buffer has not been revoked, and cancel_revoke
+ * need do nothing.
+ * RevokeValid set, Revoked set:
+ * buffer has been revoked.

Major new features in SG 3.x driver (cf SG 2.x drivers)
- SG_IO ioctl() combines function if write() and read()
data into kernel buffers and then use the CPU to copy the data into the
user space (vice versa for writes). That is called "indirect" IO due to
the double handling of data. There are two methods offered to remove the
- redundant copy: 1) direct IO which uses the kernel kiobuf mechanism and
- 2) using the mmap() system call to map the reserve buffer (this driver has
- one reserve buffer per fd) into the user space. Both have their advantages.
+ redundant copy: 1) direct IO and 2) using the mmap() system call to map
+ the reserve buffer (this driver has one reserve buffer per fd) into the
+ user space. Both have their advantages.
In terms of absolute speed mmap() is faster. If speed is not a concern,
indirect IO should be fine. Read the documentation for more information.
- ** N.B. To use direct IO 'echo 1 > /proc/scsi/sg/allow_dio' may be
- needed. That pseudo file's content is defaulted to 0. **
+ ** N.B. To use direct IO 'echo 1 > /proc/scsi/sg/allow_dio' or
+ 'echo 1 > /sys/module/sg/parameters/allow_dio' is needed.
+ That attribute is 0 by default. **
Historical note: this SCSI pass-through driver has been known as "sg" for
a decade. In broader kernel discussions "sg" is used to refer to scatter
http://www.torque.net/sg/p/sg_v3_ho.html
This is a rendering from DocBook source [change the extension to "sgml"
or "xml"]. There are renderings in "ps", "pdf", "rtf" and "txt" (soon).
+ The SG_IO ioctl is now found in other parts kernel (e.g. the block layer).
+ For more information see http://www.torque.net/sg/sg_io.html
The older, version 2 documents discuss the original sg interface in detail:
http://www.torque.net/sg/p/scsi-generic.txt
http://www.torque.net/sg/p/scsi-generic_long.txt
- A version of this document (potentially out of date) may also be found in
- the kernel source tree, probably at:
- Documentation/scsi/scsi-generic.txt .
+ Also available: <kernel_source>/Documentation/scsi/scsi-generic.txt
Utility and test programs are available at the sg web site. They are
- bundled as sg_utils (for the lk 2.2 series) and sg3_utils (for the
- lk 2.4 series).
-
- There is a HOWTO on the Linux SCSI subsystem in the lk 2.4 series at:
- http://www.linuxdoc.org/HOWTO/SCSI-2.4-HOWTO
+ packaged as sg3_utils (for the lk 2.4 and 2.6 series) and sg_utils
