[Impact]

Power consumption measurements are worse than Windows while using HW
accelerated video decoding.

[Fix]

Two commits from upstream v6.11-rc1 to add a unified queue to VCN for
more power saving.

[Test Case]

This involves attaching probes on mainboard and can only be performed by
AMD/ODM.

[Where problems could occur]

No.

[Other Info]

To apply to all kernels >= 6.8. Orauclar/Noble, OEM-6.8, OEM-6.11 are
nominated for fix.

Boyuan Zhang (2):
  drm/amdgpu/vcn: identify unified queue in sw init
  drm/amdgpu/vcn: not pause dpg for unified queue

unstable is already rebased to 6.11-rc2, so these are included there
