drm/amdgpu/vcn: Change amdgpu_vcn_sw_fini return to void

2025-09-09T20:18:46+00:00

The function amdgpu_vcn_sw_fini() returns an integer, but this number is always 0. This commit changes the amdgpu_vcn_sw_fini() return to void, and eliminates all checks to this return across different VCNs. Signed-off-by: Rodrigo Siqueira Signed-off-by: Alex Deucher

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: Check vcn state before profile switch

2025-08-29T14:09:33+00:00

The patch uses power state of VCN instances for requesting video profile. In idle worker of a vcn instance, when there is no outstanding submisssion or fence, the instance is put to power gated state. When all instances are powered off that means video profile is no longer required. A request is made to turn off video profile. A job submission starts with begin_use of ring, and at that time vcn instance state is changed to power on. Subsequently a check is made for active video profile, and if not active, a request is made.

drm/amdgpu/vcn: add instance number to VCN version message

2025-08-29T14:07:10+00:00

For multiple VCN instances case we get multiple lines of the same message like below: amdgpu 0000:43:00.0: amdgpu: Found VCN firmware Version ENC: 1.24 DEC: 9 VEP: 0 Revision: 11 amdgpu 0000:43:00.0: amdgpu: Found VCN firmware Version ENC: 1.24 DEC: 9 VEP: 0 Revision: 11 By adding instance number to the log message for multiple VCN instances, each line will clearly indicate which VCN instance it refers to.
