Hello there, I got a question about how xf86-video-amdgpu works.

Long story short, there have long been patches to some userspace programs for better/working support for the sony playstation 4. I have found patches that work with the most up to date versions of mesa, libdrm, and xf86-video-ati. However, the latest patch for xf86-video-amdgpu I could find is for version 19. So, I was just about to update the patch for the latest version, 21 if I reckon. But, here is my question.

If you look at the original ps4 patch for xf86-video-amdgpu
https://github.com/fail0verflow/ps4-radeon-patches/blob/master/xf86-video-amdgpu-1.2.0-liverpool.patch
It adds detection for the liverpool gpu (The gpu present on the ps4) and fixes the hardware cursor. But, if you look at the latest patch, all it does is fix the hardware cursor (latest for psxita too, not just ps4gentoo)
https://github.com/paranoidbashthot/ps4-overlay/blob/master/x11-drivers/xf86-video-amdgpu/files/amdgpu.patch

So, is that because those things are no longer handled by those X11 ddx drivers, or because whoever wrote that patch didn’t bother with getting the other things working? If I want to write a patch for ps4 support, I want to do it right.
