The root cause is that amdgpu driver tries to use the uninitialized work_struct in the struct drm_gpu_scheduler v2: - Rename the function to amdgpu_ring_sched_ready and move it to amdgpu_ring.c (Alex) v3: - Fix a few more checks based on Vitaly's patch (Alex) v4: - squash in fix noticed by Bert in https://gitlab.freedesktop.org/drm/amd/-/issues/3139 Fixes: 11b3b9f461c5 ("drm/sched: Check scheduler ready before calling timeout handling") Reviewed-by: Alex Deucher Signed-off-by: Vitaly Prosyak Signed-off-by: Ma Jun Signed-off-by: Alex Deucher

drm/amdgpu: Modify indirect buffer packages for resubmission

2023-06-09T16:44:15Z

When the preempted IB frame resubmitted to cp, we need to modify the frame data including: 1. set PRE_RESUME 1 in CONTEXT_CONTROL. 2. use meta data(DE and CE) read from CSA in WRITE_DATA. Add functions to save the location the first time IBs emitted and callback to patch the package when resubmission happens.
