Thanks Alex's comments
Yes, they are only in the SR-IOV HW initialization path of UVD/VCE.
Thanks & Best Wishes,

As long as this doesn't break bare metal, I'm ok with it.

Subject: [PATCH] drm/amdgpu: Use FW addr returned by PSP for VF MM
[CAUTION: External Email]
One Vega10 SR-IOV VF, the FW address returned by PSP should be
set into the init table, while not the original BO mc address.
otherwise, UVD and VCE IB test will fail under Vega10 SR-IOV
