I started in 2017 with a 2.6.35.14 patchset[1] maintained by Jürgen Urban, and ported it through 3.x, 4.x and 5.x to present day. The history goes back to 2.2.1[2] when Sony released a Linux kit. Maciej W. Rozycki and Jürgen Urban have been very helpful along the way. Most of the drivers in the 2.6 series are not present in this initial patchset. It is supposed to be fairly small, after all. Most of the other parts from 2.6 were eventually removed, reworked or expanded. For example, the 2.6 kernel uses BIOS routines for certain services. The BIOS is discarded and the kernel handles the hardware directly in this patchset. Arbitrary video mode lines are now supported. The 2.6 kernel supported n32, and 128-bit GPRs, but this patchset supports only o32, and only 32-bit GPRs although I very much hope we can retain the support for 128-bit GPRs, as suggested in the patchset cover letter, as that is a defining feature of the R5900. The input/output processor (IOP) modules, handled as firmware by the kernel, have also been reworked and updated for a modern compiler[3]. Some ideas and discussions on further development etc. can be found here: https://github.com/frno7/linux/issues > I think we may be best to split this up into 8 (or more) different > patchsets along these lines.
