Hi Leo, There are two issues here.
This change fixing the Crash while secure playback and we see below error: 2023-07-14T15:51:24.837592Z ERR kernel: [ 129.255823] amdgpu 0000:c2:00.0: amdgpu: secure submissions not supported on ring <vcn_unified_0> 2023-07-14T15:51:24.837601Z ERR kernel: [ 129.255827] [drm:amdgpu_job_run] *ERROR* Error scheduling IBs (-22) 2023-07-14T15:51:24.837603Z INFO kernel: [ 129.255834] [drm] Skip scheduling IBs! The second one : https://patchwork.freedesktop.org/patch/547587/ Fixing the garbage/corruption. With both patches playback working fine.
