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: 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: using separate VCN1_AON_SOC offset

2025-05-07T22:23:40+00:00

VCN1_AON_SOC_ADDRESS_3_0 offset varies on different VCN generations, the issue in vcn4.0.5 is caused by a different VCN1_AON_SOC_ADDRESS_3_0 offset. This patch does the following: 1. use the same offset for other VCN generations. 2. use the vcn4.0.5 special offset 3. update vcn_4_0 and vcn_5_0 Acked-by: Saleemkhan Jamadar Reviewed-by: Leo Liu Signed-off-by: Ruijing Dong Signed-off-by: Alex Deucher (cherry picked from commit 5c89ceda9984498b28716944633a9a01cbb2c90d) Cc: stable@vger.kernel.org

drm/amdgpu/vcn: fix ref counting for ring based profile handling

2025-03-19T19:54:36+00:00

We need to make sure the workload profile ref counts are balanced. This isn't currently the case because we can increment the count on submissions, but the decrement may be delayed as work comes in. Track when we enable the workload profile so the references are balanced. v2: switch to a mutex and active flag v3: fix mutex init Fixes: 1443dd3c67f6 ("drm/amd/pm: fix and simplify workload handling") Cc: Yang Wang Cc: Kenneth Feng Reviewed-by: Kenneth Feng Signed-off-by: Alex Deucher
