=== Our Source Code ===
[[https://launchpad.net/~ubuntu-nexus7/+archive/ppa|Our PPA]] contains the new or modified packages used for the 12.10 Ubuntu Nexus7 image.

The kernel code is a very slightly modified copy of the original Android kernel that the Nexus7 runs.

The Original Google repository can be found at https://android.googlesource.com/kernel/tegra/. We sync up with new branches corresponding to new firmware updates there as Google makes them available.

=== Things to get involved with ===
==== Packaging and Bug fixing ====
 * [[https://launchpad.net/~ubuntu-nexus7/+archive/ppa | Patched packages ]]. These patches will make it to Ubuntu 12.10 soon. If you have upload rights and know the packages well, you can help us getting the patches from [[https://launchpad.net/~ubuntu-nexus7/+archive/ppa|our PPA]] into 12.10.
 * You can help us [[Bugs/HowToTriage|triage]], [[Bugs/Upstream|upstream]] and [[http://developer.ubuntu.com/packaging/html/fixing-a-bug.html|fix bugs]]. The list of bugs for the Nexus 7 can be found here: https://bugs.launchpad.net/ubuntu-nexus7

To get started, please read the [[http://developer.ubuntu.com/packaging/html/|first chapters of the packaging guide]]. To get a `armhf` pbuilder up and running simply run: {{{
pbuilder-dist (quantal|raring) armhf create
pbuilder-dist (quantal|raring) armhf build somepackage_version.dsc
}}}

Once the build is complete, cd into your ~/pbuilder/(quantal|raring)-armhf_result directory and you can copy over the .deb files and install them on your Nexus7.

==== Measuring and debugging ====
 * [[../MeasuringPowerConsumption | Measuring Power Consumption]]. Everybody wants devices to run for ages without having to recharge. Help out here!
 * [[../MeasuringMemoryUsage | Measuring Memory Usage]]. It's important we get low memory foot-print. By measuring and finding issues, you can help us out a lot.
 * [[../BrowsingSimulation | Simulation Realistic Usage Using A Browser]]. When you are profiling what eats your battery or memory, it is important to use a realistic behaviour pattern. Here is a tool that does that within Chromium.


=== General info ===
[[../KernelBuild | To build the kernel]] follow these instructions.

You can reach us in the #ubuntu-arm irc channel on irc.freenode.net. General discussion happens on the [[https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel|ubuntu-devel]] mailing list. (For Desktop issues you might want to refer to https://lists.ubuntu.com/mailman/listinfo/ubuntu-desktop and for kernel issues to https://lists.ubuntu.com/mailman/listinfo/kernel-team)
