drm/amdgpu: Do not fiddle with the idle workers too much

2026-07-01T15:56:47+00:00

Idle workers only need to be canceled or pushed back if we are potentially idle. Make the both operations conditional on the pre-increment and post- decrement status of the in-flight job counter.

drm/amdgpu: give each kernel job a unique id

2025-09-01T05:19:31+00:00

Userspace jobs have drm_file.client_id as a unique identifier as job's owners. For kernel jobs, we can allocate arbitrary values - the risk of overlap with userspace ids is small (given that it's a u64 value). In the unlikely case the overlap happens, it'll only impact trace events. Since this ID is traced in the gpu_scheduler trace events, this allows to determine the source of each job sent to the hardware. To make grepping easier, the IDs are defined as they will appear in the trace output.

drm/amdgpu: fix shift-out-of-bounds in amdgpu_debugfs_jpeg_sched_mask_set

2025-08-27T17:57:51+00:00

Fix a UBSAN shift-out-of-bounds warning in amdgpu_debugfs_jpeg_sched_mask_set when the shift exponent reaches or exceeds 32 bits. The issue occurred because a 32-bit integer '1' was being shifted by up to 32 bits, which is undefined behavior. Replace '1' with '1ULL' to ensure 64-bit arithmetic, matching the u64 type of 'val' and preventing the shift overflow. This is consistent with the existing mask calculation that already uses 1ULL. The error manifested as: UBSAN: shift-out-of-bounds in drivers/gpu/drm/amd/amdgpu/amdgpu_jpeg.c:373:17 shift exponent 32 is too large for 32-bit type 'int' v2: remove debug log Reviewed-by: Lijo Lazar Suggested-by: Lijo Lazar Signed-off-by: Jesse Zhang Signed-off-by: Alex Deucher
