Userspace wants to run jobs on a specific sdma ring for verification purposes. This debugfs entry helps to disable or enable submitting jobs to a specific ring. This entry is populated only if there are at least two or more cores in the sdma ip. Signed-off-by: Jesse Zhang Suggested-by: Alex Deucher Reviewed-by: Tim Huang Signed-off-by: Alex Deucher

drm/amdgpu: add amdgpu_gfx_sched_mask and amdgpu_compute_sched_mask debugfs

compute/gfx may have multiple rings on some hardware. In some cases, userspace wants to run jobs on a specific ring for validation purposes. This debugfs entry helps to disable or enable submitting jobs to a specific ring. This entry is populated only if there are at least two or more cores in the gfx/compute ip.

JPEG_4_0_3 has up to 32 jpeg cores and a single mjpeg video decode will use all available cores on the hardware. This debugfs entry helps to disable or enable job submission to a cluster of cores or one specific core in the ip for debugging. The entry is populated only if there is at least two or more cores in the jpeg ip. Signed-off-by: Sathishkumar S Reviewed-by: Leo Liu Signed-off-by: Alex Deucher

drm/amdgpu: Remove debugfs amdgpu_reset_dump_register_list

2024-08-06T14:42:09Z

There are some problem with existing amdgpu_reset_dump_register_list debugfs node. It is supposed to read a list of registers but there could be cases when the IP is not in correct power state. Register read in such cases could lead to more problems. We are taking care of all such power states in devcoredump and dumping the registers of need for debugging. So cleaning this code and we dont need this functionality via debugfs anymore. Reviewed-by: Christian König Signed-off-by: Sunil Khatri Signed-off-by: Alex Deucher

drm/amdgpu: fix invadate operation for pg_flags

2024-05-23T19:09:50Z

Since the type of pg_flags is u32, adev->pg_flags >> 16 >> 16 is 0 regardless of the values of its operands. So removing the operations upper_32_bits and lower_32_bits. Signed-off-by: Jesse Zhang Suggested-by: Tim Huang Reviewed-by: Tim Huang Signed-off-by: Alex Deucher
