[PATCH] drm/amdgpu: Complete multimedia bandwidth interface
Bokun Zhang
bokun.zhang at amd.com
Thu May 13 05:19:49 UTC 2021
- Update SRIOV PF2VF header with latest revision
- Extend existing function in amdgpu_virt.c to read MM bandwidth config
from PF2VF message
- Add SRIOV Sienna Cichlid codec array and update the bandwidth with
PF2VF message
