Prepare the system

Your system must be prepared for Debian kernel compilation. You will also have to extract files from an ISO image. To get all the required tools, simply issue the command (as root):

apt-get install kernel-package device-tree-compiler build-essential libncurses5-dev fakeroot git-core

Get the kernel sources

You can either download the most recent official kernel sources from, or fetch the official Sony sources from Geoff Levand's git repository. The latter version of the sources are likely to contain much more up-to-date specific patches for the PS3. In addition, fetching the sources from is a straightforward process, thus this section only describes how to build the sources from the Sony sources.

First fetch of the sources

From one of your local user's home subdirectories, issue the command:

git clone

which will create a ps3-linux directory, and fetch a copy of the git repository in it.

Beware the latest revision of the sources you just downloaded are likely to be a working version of the sources, meaning it might contain bugs. You can switch to another git commit using the git checkout command. For instance, for fetching the (supposedly) stable release of the version 2.6.32, issue the command (from the ps3-linux directory):

git checkout v2.6.32

Remember you can list all the possible tag names for use with git checkout using the git tag command. Whenever you want to go back to the latest revision of the sources, use the master specific tag.

Subsequent fetches

If you alrady have a clone of the git repository, you can update it, first by cleaning the changes you made, with the command:

git checkout -f

Then, fetch and apply the latest upstream changes:

git pull

You can now get the new tag list, with the git tag command, and switch to any of them, using the git checkout command.

Kernel setup

The default ps3 configuration generally fits most needs for linux users on the ps3 (casual users as well as developers). You can generate the default configuration file by issuing the command from the ps3-linux directory:

make ps3_defconfig

After having setup the default ps3 configuration, you can eventually check and modifiy the configuration using the command:

make menuconfig

Kernel packages generation

Once the setup is done, you can generate the kernel image, headers and source packages using the commands:

echo \#\!/bin/sh > ./scripts/setlocalversion
make-kpkg --initrd --rootcmd=fakeroot --append-to-version=-ps3 --revision=20090728 kernel_image kernel_headers kernel_source

At every build, better use a different argument for the --revision argument. I generally use the current date as revision number.

If everything goes right, the package files will be found in the parent of the ps3-linux directory.

Packages installation and bootloader setup

In a Debian system, simply install the packages with the command:

dpkg -i linux-*-2.6.30*_20090728*.deb

Obviously, change the version and revision numbers to the correct ones.

This will install the kernel, and setup the bootloader with current kernel as the new one, and the "old" kernel as the previoulsy installed one.
