Linux kernel development process currently consists of a few different
main kernel "branches" and lots of different subsystem-specific kernel
branches. These different branches are:
- - main 2.6.x kernel tree
- - 2.6.x.y -stable kernel tree
- - 2.6.x -git kernel patches
+ - main 3.x kernel tree
+ - 3.x.y -stable kernel tree
+ - 3.x -git kernel patches
- subsystem specific kernel trees and patches
- - the 2.6.x -next kernel tree for integration tests
+ - the 3.x -next kernel tree for integration tests

+3.x kernels are maintained by Linus Torvalds, and can be found on
+kernel.org in the pub/linux/kernel/v3.x/ directory. Its development
process is as follows:
- As soon as a new kernel is released a two weeks window is open,
during this period of time maintainers can submit big diffs to
released according to perceived bug status, not according to a
preconceived timeline."

This is the recommended branch for users who want the most recent stable
kernel and are not interested in helping test development/experimental
versions.

documents what kinds of changes are acceptable for the -stable tree, and
how the release process works.
-2.6.x -git patches
+3.x -git patches
------------------
These are daily snapshots of Linus' kernel tree which are managed in a
git repository (hence the name.) These patches are usually released
accepted, or rejected. Most of these patchwork sites are listed at
http://patchwork.kernel.org/.

+3.x -next kernel tree for integration tests
---------------------------------------------
-Before updates from subsystem trees are merged into the mainline 2.6.x
+Before updates from subsystem trees are merged into the mainline 3.x
tree, they need to be integration-tested. For this purpose, a special
testing repository exists into which virtually all subsystem trees are
pulled on an almost daily basis:
- http://git.kernel.org/?p=linux/kernel/git/sfr/linux-next.git
+ http://git.kernel.org/?p=linux/kernel/git/next/linux-next.git
http://linux.f-seidel.de/linux-next/pmwiki/
This way, the -next kernel gives a summary outlook onto what will be
seen enough historic cpu load data to determine the appropriate
workload. Default is 80000 uS.
-go_maxspeed_load: The CPU load at which to ramp to max speed. Default
-is 85.
+hispeed_freq: An intermediate "hi speed" at which to initially ramp
+when CPU load hits the value specified in go_hispeed_load. If load
+stays high for the amount of time specified in above_hispeed_delay,
+then speed may be bumped higher. Default is maximum speed.
+
+go_hispeed_load: The CPU load at which to ramp to the intermediate "hi
+speed". Default is 85%.
+
+above_hispeed_delay: Once speed is set to hispeed_freq, wait for this
+long before bumping speed higher in response to continued high load.
+Default is 20000 uS.

+hispeed_freq until zero is written to this attribute. If zero, allow

tcp_sack - BOOLEAN
Enable select acknowledgments (SACKS).
Similarly, if the power.use_autosuspend field isn't set then the autosuspend
helper functions will behave just like the non-autosuspend counterparts.
+Under some circumstances a driver or subsystem may want to prevent a device
+from autosuspending immediately, even though the usage counter is zero and the
+autosuspend delay time has expired. If the ->runtime_suspend() callback
+returns -EAGAIN or -EBUSY, and if the next autosuspend delay expiration time is
+in the future (as it normally would be if the callback invoked
+pm_runtime_mark_last_busy()), the PM core will automatically reschedule the
+autosuspend. The ->runtime_suspend() callback can't do this rescheduling
+itself because no suspend requests of any kind are accepted while the device is
+suspending (i.e., while the callback is running).
+
The implementation is well suited for asynchronous use in interrupt contexts.
However such use inevitably involves races, because the PM core can't
synchronize ->runtime_suspend() callbacks with the arrival of I/O requests.
Procedure for submitting patches to the -stable tree:
- Send the patch, after verifying that it follows the above rules, to
- stable@kernel.org. You must note the upstream commit ID in the changelog
- of your submission.
+ stable@vger.kernel.org. You must note the upstream commit ID in the
+ changelog of your submission.
- To have the patch automatically included in the stable tree, add the tag
- Cc: stable@kernel.org
+ Cc: stable@vger.kernel.org
in the sign-off area. Once the patch is merged it will be applied to
the stable tree without anything else needing to be done by the author
or subsystem maintainer.

2. Find which bus connects to the desired device
-Run "cat /proc/bus/usb/devices", and find the T-line which corresponds to
-the device. Usually you do it by looking for the vendor string. If you have
-many similar devices, unplug one and compare two /proc/bus/usb/devices outputs.
-The T-line will have a bus number. Example:
