Running Linux on the Playstation 2
At the moment (May 2010) the newest Linux kernel version for the Playstation 2 is 2.4.17mvl21, which can be downloaded from the Sony website. It is a heavily patched 2.4.17 linux-mips kernel. Patches were done by Montavista.
The reason why newer kernel versions aren't available is because the Playstation 2 toolchain is too old to build newer kernels (GCC 2.95.2 and Binutils 2.9). Some people at PS2Dev have ported GCC 3.2.2 and Binutils 2.14 to the Playstation 2, but isn't developed to run Linux (only static ELF's).
On the PS2 Linux does not run on the bare hardware but on an abstraction layer called RTE (Run Time Environment). The RTE was partly reimplemented as open source. The open source variant is called TGE (The Great Experiment).
The open source bootloader Kernelloader loads the required RTE/TGE modules before starting the Linux kernel. For 2.6 kernels it could also be possible to append the required RTE/TGE modules directly to the kernel image instead. On Kernelloader's project page there are some patches available for Linux 2.4.17mvl21 improving Linux compatibility especially with the newer slim PS2 models.
