AMD Working On More Precise GPU Reset Capabilities For Their Linux Driver
While the hope remains that GPU resets are a very infrequent task, AMD Linux driver engineers have recently been working on the ability to support a per-queue GC reset capability for more precise reset capabilities when needed.
With the latest patches for the AMDGPU kernel driver code, the driver would be able to reset the graphics/compute ring where an error occurs and to just lose the jobs pending in that queue as opposed to carrying out a full GPU reset. An updated set of 53 patches were posted today for introducing reset capabilities on a per-ring basis in the AMDGPU driver. This is then wired up across the recent generations of AMD graphics processors, including the upcoming GFX12 (RDNA4) hardware.
