drm/amdgpu: move UVD and VCE sched entity init after sched init

2023-11-10T16:33:08+00:00

We need kernel scheduling entities to deal with handle clean up if apps are not cleaned up properly. With commit 56e449603f0ac5 ("drm/sched: Convert the GPU scheduler to variable number of run-queues") the scheduler entities have to be created after scheduler init, so change the ordering to fix this. v2: Leave logic in UVD and VCE code Fixes: 56e449603f0a ("drm/sched: Convert the GPU scheduler to variable number of run-queues") Reviewed-by: Christian König Reviewed-by: Luben Tuikov Signed-off-by: Alex Deucher Cc: ltuikov89@gmail.com

drm/amd: Split up UVD suspend into prepare and suspend steps

2023-10-13T15:01:04+00:00

amdgpu_uvd_suspend() allocates memory and copies objects into that allocated memory. This fails under memory pressure. Instead move majority of this code into a prepare step when swap can still be allocated. Reviewed-by: Christian König Signed-off-by: Mario Limonciello Signed-off-by: Alex Deucher

drm/amdgpu: use job and ib structures directly in CS parsers

Instead of providing the ib index provide the job and ib pointers directly to the patch and parse functions for UVD and VCE. Also move the set/get functions for IB values to the IB declerations. Signed-off-by: Christian König Acked-by: Andrey Grodzovsky Signed-off-by: Alex Deucher
