Hi, I made a guide for PS4 Gentoo "DIY" installation, it still needs to be improved, but I'm sharing it if anyone wants to read it and knows how to do something.
I will update libdrm, xf86-video-amdgpu and mesa from the gentoo repository into my overlay, so the version will always match the dependencies.
And if anyone wants to make any corrections, everything is on your side too.
Have a nice day/night.
