DESCRIPTION:Speakers: Timur Kristóf (Valve)\nAt XDC 2025 I promised that 
 old AMD GPUs would work great on Linux\, starting from GCN 1 up to GCN 4. 
 In this talk\, I'd like to present the progress on that work and what I le
 arned from it.\n\nIn the current economic situation of our world\, people 
 may have to use GPUs for longer\, and replace them less often. And when an
  old GPU is replaced\, it doesn’t disappear\, it goes to somebody who up
 grades an even older GPU. Eventually it will reach somebody that can’t a
 fford a better one. My goal with this work is to make Linux gaming a good 
 experience also for those who use old AMD GPUs\, and learn Linux kernel de
 velopment in the process.\n\nWhat did this work entail?\n\nI'll talk about
  implementing various display features\, VCE support\, DRM format modifier
 s\, Vulkan\, improved GPU hang recovery\, sparse bindings\, fixing memory 
 management issues\, power management bugs and making some GPUs boot that p
 reviously never worked on Linux.\n\nWith that\, GCN GPUs can now run a mod
 ern Linux graphics stack using the amdgpu kernel driver and the RADV Vulka
 n driver.\n\nhttps://indico.freedesktop.org/event/12/contributions/545/
