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.

  * Read the [[compat|hacking on compat documentation]].
  * Read the [[Hacking|hacking on compat-drivers documentation]].

<h2>TODO list</h2>

Read the [[Hacking#TODO|hacking TODO]] for a list of wish items we should be working towards.
