Latest revision as of 00:30, 7 January 2014
There is a set of 7 patches available sent to the linuxppc mailing list on 08 March 2007, which have to be applied to Linux 2.6.20. If you're interested in kernel development and/or adding new features, please take a look at Linux Kernel Development.
- (patch 1/7) xenon: add PCI Vendor ID: Microsoft
- (patch 2/7) xenon: add platform support
- (patch 3/7) xenon: udbg support (ugly)
- (patch 4/7) xenon: add southbridge ethernet support
- (patch 5/7) xenon: add SATA support
- (patch 6/7) xenon: add SMC support
- (patch 7/7) xenon: add framebuffer support (ugly)
To run linux, you need to use the Linux Bootloader available right now. To compile the kernel, you need to set up a [cross compiler] toolchain (unless you already have another PowerPC Linux machine).
Prerequisites
The minimal requirements for successfully cross compiling the Linux Kernel for your Xbox are (unverified):
- A machine running a Linux based OS (most likely your PC)
- Sources for the Linux Kernel
- The Xenon patch or patchset
- Binutils (targeting the powerpc architecture)
- GCC (targeting the powerpc architecture)
Configuring and Compiling the Kernel
- Get the source for the Kernel from kernel.org and unpack it.
cd
wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.21.tar.bz2
tar -xvjf linux-2.6.21.tar.bz2
- Download and apply the Xenon patch/patchset matching your kernel.
cd linux-2.6.21/

wget http://op-co.de/xbox360/2.6.21/$patch
patch -p1 < $patch
done
- Configure the Kernel. You can manually fetch a configuration file from the internet (e.g. here) and type:
make ARCH=powerpc CROSS_COMPILE=powerpc64-unknown-linux-gnu- oldconfig
- Of course, you can fine-tune your Kernel configuration to fit your needs using
make ARCH=powerpc CROSS_COMPILE=powerpc64-unknown-linux-gnu- menuconfig
- Build the Kernel by typing:
make ARCH=powerpc CROSS_COMPILE=powerpc64-unknown-linux-gnu- all
If everything goes well, you will end up with a file arch/powerpc/boot/zImage.xenon containing the kernel which can be loaded by the XeLL.
Configuring and Compiling the 2.6.38.8 Kernel (experimental)
Patches for recent kernels are available now, but considered highly experimental.
- Get the source for the Linux 2.6.38.8 Kernel from kernel.org and unpack it.
wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.38.8.tar.bz2
tar -xvjf linux-2.6.38.8.tar.bz2
- Download and apply the experimental Xenon patch & kernel config.
wget -O xenon_config http://sourceforge.net/projects/free60/files/Linux%20Kernel/xenon_config/download
wget -O patch-2.6.38.8-xbox0.11.1.diff http://sourceforge.net/projects/free60/files/Linux%20Kernel/v2.6.38/patch-2.6.38.8-xbox0.11.1.diff/download
cd linux-2.6.38.8/
patch -p1 < ../patch-2.6.38.8-xbox0.11.1.diff
cp ../xenon_config .config
- Configure the Kernel.
make ARCH=powerpc CROSS_COMPILE=powerpc64-unknown-linux-gnu- menuconfig
- Build the Kernel by typing:
make ARCH=powerpc CROSS_COMPILE=powerpc64-unknown-linux-gnu- all
If everything goes well, you will end up with a file arch/powerpc/boot/zImage.xenon containing the kernel which can be loaded by the XeLL.
Remember, these patches are Experimental!
Rootfilesystem via NFS
- Configure the kernel (CONFIG_CMDLINE in .config) for NFS (see NFS-Tutorial for details) to match your local setup.
- example: CONFIG_CMDLINE="root=nfs video=xenonfb console=tty0 nfsroot=192.168.1.1:/mnt/nfsroot/xbox rw ip=dhcp"
- Make sure that the IP Plug and Play (CONFIG_IP_PNP* in .config) options match your ip setup method.
