drm/amdgpu/vcn: add a helper framework for engine resets

2025-07-16T20:16:58Z

With engine resets we reset all queues on the engine rather than just a single queue. Add a framework to handle this similar to SDMA. Reviewed-by: Sathishkumar S Tested-by: Sathishkumar S Signed-off-by: Alex Deucher

drm/amdgpu/vcn: using separate VCN1_AON_SOC offset

2025-05-07T22:23:40Z

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

2025-03-19T19:54:36Z

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
