drm/amdgpu: set an error on all fences from a bad context

2025-10-23T14:24:34Z

[ Upstream commit ff780f4f80323148d43198f2052c14160c8428d3 ] When we backup ring contents to reemit after a queue reset, we don't backup ring contents from the bad context. When we signal the fences, we should set an error on those fences as well. v2: misc cleanups v3: add locking for fence error, fix comment (Christian) v4: fix wrap around, locking (Christian) Fixes: 77cc0da39c7c ("drm/amdgpu: track ring state associated with a fence") Reviewed-by: Christian König Signed-off-by: Alex Deucher Signed-off-by: Sasha Levin

drm/amdgpu: handle wrap around in reemit handling

drm/amdgpu: track ring state associated with a fence

2025-07-16T20:14:11Z

We need to know the wptr and sequence number associated with a fence so that we can re-emit the unprocessed state after a ring reset. Pre-allocate storage space for the ring buffer contents and add helpers to save off and re-emit the unprocessed state so that it can be re-emitted after the queue is reset.

drm/amdgpu: remove job parameter from amdgpu_fence_emit()

2025-06-30T15:57:06Z

What we actually care about is the amdgpu_fence object so pass that in explicitly to avoid possible mistakes in the future. The job_run_counter handling can be safely removed at this point as we no longer support job resubmission. Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: switch job hw_fence to amdgpu_fence

2025-06-18T16:19:21Z

Use the amdgpu fence container so we can store additional data in the fence. This also fixes the start_time handling for MCBP since we were casting the fence to an amdgpu_fence and it wasn't.
