Additionally, /sys/power/disk can be used to turn on one of the

the kernel to disable nonboot CPUs and freeze tasks, wait for 5
seconds, unfreeze tasks and enable nonboot CPUs. If it is in

the kernel to disable nonboot CPUs and freeze tasks, shrink
memory, suspend devices, wait for 5 seconds, resume devices,

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.

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
Q1. Are there any limitations on using the MSI?

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.

You won't find many ff-aware linux applications anyway.

---------
0. Notes
--------
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.
Driver updated for kernel 2.6.17.11. (Based on a patch for 2.6.11.4.)
The jstest-program from joystick-1.2.15 (jstest-version 2.1.0) reports
8 axes and 10 buttons.
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)
Alls 8 axes work, though they all have the same range (-32768..32767)
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.
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.

You cannot use the fast gettimeoffset functions, i.e.,

unsigned long calibrate_div32_gettimeoffset(void);

You can use null_gettimeoffset() will gives the same time resolution as
jiffy. Or you can implement your own gettimeoffset (probably based on
some ad hoc hardware on your machine.)
c) The following sub steps assume your CPU has counter register.
Do you plan to use the CPU counter register as the timer interrupt
or use an exnternal timer?
In order to use CPU counter register as the timer interrupt source, you
must know the counter speed (mips_counter_frequency). It is usually the

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) !
