drm/amdgpu: compare MES firmware version ucode for gfx11

2026-06-04T19:25:46+00:00

MES firmware should report the same version whether read from the register or from the firmware ucode binary. This is not always the case, so add a log when they mismatch. Signed-off-by: Sunil Khatri Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: Support MES suspend_all_sdma_gangs

drm/amdkfd: Reset queue/pipe in MES

2026-04-28T18:46:00+00:00

When removing queues fails, KFD calls amdgpu_mes to detect and reset hung queues, then cleans up those hung queues in KFD. Suggested-by: Jonathan Kim Signed-off-by: Amber Lin Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: Missing multi-XCC support in MES

2026-04-28T18:42:36+00:00

In a multi-XCC GPU, pass the master XCC's ID to amdgpu_mes_suspend, amdgpu_mes_resume, and detect_and_reset_hung_queues so the command will be sent to the matching master MES when the compute partition mode is not SPX. Signed-off-by: Amber Lin Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu/mes: Remove idr leftovers v2

2026-01-27T23:02:06+00:00

Commit cb17fff3a254 ("drm/amdgpu/mes: remove unused functions") removed most of the code using these IDRs but forgot to remove the struct members and init/destroy paths. There is also interrupt handling code in SDMA 5.0 and 5.2 which appears to be using it, but is is unreachable since nothing ever allocates the relevant IDR. We replace those with one time warnings just to avoid any functional difference, but it is also possible they should be removed. v2: also fix up gfx_v12_1.c and sdma_v7_1.c Signed-off-by: Tvrtko Ursulin References: cb17fff3a254 ("drm/amdgpu/mes: remove unused functions") Cc: Alex Deucher Reviewed-by: Christian König Signed-off-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: Update MES VM_CNTX_CNTL for XNACK off for GFX 12.1

2025-12-10T22:39:09+00:00

Currently, we do not turn off retry faults in VM_CONTEXT_CNTL value when passing it to MES if XNACK is off. This creates a situation where XNACK is disabled in SQ but enabled in UTCL2, which is not recommended. As a result, turn off/on retry faults in both SQ and UTCL2 when passing vm_context_cntl value to MES if XNACK is disabled/enabled.
