-In order to backport the Linux kernel we must divide and conquer the tasks at hand.

-

-This is now deprecated use [[Documentation/backports/hacking|hacking on backports]].

-<h1>Backport components</h1>

-

-There are currently two components to the backports effort.

-

-<h2>compat</h2>

-

-compat is a shared module / headers that implements newer features for usage on older kernels.

-

- * [https://github.com/mcgrof/compat git://github.com/mcgrof/compat.git] [[compat|compat documentation]]

-

-<h2>compat-drivers</h2>

-

-compat-drivers is the framework that pulls code from the Linux kernel, adds the compat module and backports features that compat could not backport within its module / headers.

-

- * [https://github.com/mcgrof/compat-drivers git://github.com/mcgrof/compat-drivers.git] [[compat-drivers|compat-drivers documentation]]

-<h1>Getting all required code</h1>

-

-To be able to make releases and test building releases however you need quite a bit more code. The setup is simplified with scripts from the compat.git tree. To set your system up for the first time you can run:

-

-<code>

-<pre>

-wget https://github.com/mcgrof/compat/raw/master/bin/get-compat-trees

-wget https://github.com/mcgrof/compat/raw/master/bin/get-compat-kernels

-

-chmod 755 get-compat-trees get-compat-kernels

-

-./get-compat-trees

-./get-compat-kernels

-</pre>

-</code>

-

-<h1>Hacking on the project</h1>

-

-You should realize that there are a few components to the project and that although they are used together each one can be considered independent of each other.

-<h2>TODO list</h2>

-Read the [[Hacking#TODO|hacking TODO]] for a list of wish items we should be working towards. \ No newline at end of file
