Bug description:
[Impact]
It fails to resume from S3 with below error messages
Nov 17 03:15:27 u kernel: amdgpu 0000:04:00.0:[drm:amdgpu_ring_test_helper
[amdgpu]] ERROR ring vcn_dec test failed (-110)
Nov 17 03:15:27 u kernel: [drm:amdgpu_device_ip_resume_phase2 [amdgpu]]
ERROR resume of IP block <vcn_v1_0> failed -110
Nov 17 03:15:27 u kernel: [drm:amdgpu_device_resume [amdgpu]] ERROR
amdgpu_device_ip_resume failed (-110).
[Fix]
AMD provides the 2 commits in 5.9-rc1 to fix this issue, and groovy has these
commits from stable update.
429f3d24384b drm/amdgpu: asd function needs to be unloaded in suspend phase
90937420c44f drm/amdgpu: add TMR destory function for psp
[Test]
Verified on problematic Dell machineļ¼and it passes 500 S3 test.
[Where problems could occur]
TMR will be created after resumed, so it should be destroyed while entering
S3. The patch does what is required, should be pretty safe to include this
commit.
