drm/amd/amdgpu: SRIOV full reset issue with VCN
- After a full reset, VF's FB will be cleaned. This
includes the VCN's fw_shared memory.
However, there is no suspend-resume routine for
SRIOV VF. Therefore, the data in the fw_shared
memory will be lost forever and it causes engine
hang later on.
We must repopulate the data in fw_shared during
SRIOV hw_init
