Android Kernel Download
The main Google repository with Android source code is at: http://android.git.kernel.org/
There are (as of September 2009) 4 main separate kernel repositories at that site:
- common
- experimental
- msm
- omap
To download one of these and use it directly, you can use git. For example:
git clone git://android.git.kernel.org/kernel/common.git
To add one of these to your overall Android repository scheme, you add the appropriate kernel repository to your local_manifest.xml file. (???)
Note that when you download the rest of the Android source code, using the 'repo' command, you do NOT automatically get a kernel tree included. (That is, a kernel git tree is not referenced in the default Android manifest file, when you use repo following the instructions at http://source.android.com/download )
