AMD Enables Per-Queue Resets For Newer GPUs & Other Linux 6.12 AMDGPU Changes

We are just a week or two out from the start of the Linux 6.12 merge window and AMD has submitted a final round of feature updates to DRM-Next of kernel graphics driver changes they want to round out AMDGPU/AMDKFD for this next cycle.

This week's batch of "new stuff for 6.12" mostly consists of driver fixes as well as updates to various IP blocks -- including continued work on GFX12 support for upcoming RDNA4 graphics cards.

This batch of updates does build off the per-queue resets and process isolation support sent out last month as part of earlier pulls for AMDGPU in DRM-Next for Linux 6.12. Initially that per-queue reset support for more fine-grained reset handling was only enabled for GFX9 hardware. Now with Friday's update the per-queue reset support is working across GFX10 / GFX11 / GFX12 RDNA graphics processors.

This week's pull also has DCN3.5 fixes for Strix Point / RDNA3.5 hardware, Panel Replay fixes, SR-IOV fixes, pipe reset support for GC9.4.3 Instinct hardware, display flickering fixes, and display sharpening updates.
