Overview
The current release is based on a generic Ubuntu kernel 3.13.0 with a few modifications made by CompuLab. The package include the following:
- linux_3.13.0.orig.tar.gz - mainline Linux 3.13.0 sources
- linux_3.13.0-30.55.diff - Ubuntu patch
- compulab.cm-igt.diff - CompuLab patch
- config-3.13.0.30-compulab.cm-igt - CompuLab config file
- Resulting .deb files are also included
Development
You can change the kernel and compile your own .deb files:
|
Compile on a 64-bit machine with Ubuntu or LinuxMint on another compatible distro |
- Install the programs and tools required for kernel building
$ sudo apt-get install libncurses5 libncurses5-dev kernel-package
- Prepare sources, apply patches and setup config file
$ cd /path/to/igt-linux/kernel $ tar -xvzf linux_3.13.0.orig.tar.gz $ cd linux-3.13 $ patch -p1 < ../patches/linux_3.13.0-30.55.diff $ patch -p1 < ../patches/compulab.cm-igt.diff $ cp ../config-3.13.0.30-compulab.cm-igt .config
- Make your modifications and configure the new kernel
$ make menuconfig optional: change CONFIG_LOCALVERSION="-compulab.cm-igt" to "-yourname.cm-igt"
- If you have a more than one processor or more than one core, you can speed things up by running concurrent compile commands. Setup CONCURRENCY_LEVEL=8 for 8 cores
$ export CONCURRENCY_LEVEL=8
- Compile the kernel and create the .deb packages
$ fakeroot make-kpkg --initrd --revision=10.00 kernel_image kernel_headers optional: change revision=10.00 to another custom string, it will appear as part of the .deb file
- The linux-image-*.deb and linux-headers-*.deb packages are created in the parent directory
- Install new .deb packages on the CM-iGT
sudo dpkg -i linux-*.deb
