Patch #6 the drm/amdgpu prefix is missing from the subject line, apart
from that the patch is Reviewed-by: Christian König

For patches #20-#26 I'm not sure if those won't break the driver in
between. Alex what do you think?
Patches #28 and #29 look good to me as well, but I leave the review to
Sunil he wrote that code and should know it best.
Patch #30:
+ int ret = 0;
...
+ ret = SOC15_WAIT_ON_RREG(VCN, inst, mmUVD_STATUS, UVD_STATUS__IDLE,
That will get you a warning for an unneeded local variable
initialization from the automated checkers.
The init was only necessary because we previously had the loop over all
instances here.
Patch #31:
int inst = ip_block->instance;
int ret = 1;
if (adev->vcn.harvest_config & (1 << inst))
return ret;
ret &= (RREG32_SOC15(VCN, inst, mmUVD_STATUS) == UVD_STATUS__IDLE);
return ret;
That code looks really strange now, maybe drop the local variable ret.
Regards,
Christian
