2025-09-15drm/amdgpu: adjust MES API used for suspend and resumeJesse.Zhang
Use the suspend and resume API rather than remove queue and add queue API. The former just preempts the queue while the latter remove it from the scheduler completely. There is no need to do that, we only need preemption in this case. V2: replace queue_active with queue state v3: set the suspend_fence_addr v4: allocate another per queue buffer for the suspend fence, and set the sequence number. also wait for the suspend fence. (Alex) v5: use a wb slot (Alex) v6: Change the timeout period. For MES, the default timeout is 2100000; /* 2100 ms */ (Alex) Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Jesse Zhang <Jesse.Zhang@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2025-09-05drm/amdgpu/userq: add a detect and reset callbackJesse.Zhang
Add a detect and reset callback and add the implementation for mes. The callback will detect all hung queues of a particular ip type (e.g., GFX or compute or SDMA) and reset them. v2: increase reset counter and set fence force completion v3: Removed userq_mutex in mes_userq_detect_and_reset since the driver holds it when calling Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Jesse Zhang <Jesse.Zhang@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2025-04-22drm/amdgpu: switch from queue_active to queue stateAlex Deucher
Track the state of the queue rather than simple active vs not. This is needed for other states (hung, preempted, etc.). While we are at it, move the state tracking into the user queue front end code.
