I Tested proposed kernel 6.14.0-1014-oem against an HP Mint (Strix-Halo) To test this patch I ran a few different image generation workloads using Comfy-Ui via ROCm. For gaming I ran a few different benchmark cycles inside of Cyberpunk, as well as a few generic 3D benchmarks to ensure gaming/3D render stability. No notable issues, crashes, or errors were detected during any of the testing process.

The hangs occur in the MES scheduler. A workaround has been developed for this situation in the MES scheduler and in the GPU driver. [Fix] The MES scheduler change is in MES 0x7f for GFX11 products and 0x82 in GFX12 products. * The kernel change is: https://lore.kernel.org/amd-gfx/[email protected]/ * For OEM 6.14 this also has a dependency on https://git.kernel.org/torvalds/c/15d8c92f107c1 to cleanly backport. The kernel change will only be enabled if new enough MES scheduler microcode is installed. [Test Case] Run pytorch, ensure that system doesn't hang. Run some games in steam, ensure system doesn't hang. [Where problems can go wrong] The workaround applies to all jobs sent to MES scheduler. It will be localized to GFX11 and GFX12 machines. If there was a problem from this change it could manifest as a hang on system.
