2025-05-07drm/amdgpu/vcn: using separate VCN1_AON_SOC offsetRuijing Dong1-1/+0
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 <saleemkhan.jamadar@amd.com> Reviewed-by: Leo Liu <leo.liu@amd.com> Signed-off-by: Ruijing Dong <ruijing.dong@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> (cherry picked from commit 5c89ceda9984498b28716944633a9a01cbb2c90d) Cc: stable@vger.kernel.org
2025-03-19drm/amdgpu/vcn: fix ref counting for ring based profile handlingAlex Deucher1-0/+3
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.
