Open-source developer Andy Nguyen recently demonstrated porting Linux to the Sony PlayStation 5. The PS5 notably uses a custom AMD SoC and with some patches is able to play nicely with the open-source AMD graphics driver stack.

Beyond just demonstrating an experimental Linux port for the Sony PlayStation 5, Andy Nguyen has followed through and begun upstreaming some of the patches where relevant. Recently there have been AMDGPU kernel graphics driver and Mesa patches for dealing with the Sony PlayStation 5 GPU that is a combination of IP from different generations and on the CPU side is Zen 2 derived.
