Subject: drm/amd/amdgpu/sriov temporarily skip ras,dtm,hdcp for arcturus VF
X-Git-Tag: v5.10.7~3692^2~11^2~3
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ef1c0cbcd1e0db497ad0d7128e7157f0e3788b14;p=platform%2Fkernel%2Flinux-rpi.git

drm/amd/amdgpu/sriov temporarily skip ras,dtm,hdcp for arcturus VF

Temporarily skip ras,dtm,hdcp initialize and terminate for arcturus VF
Currently the three features haven't been enabled at SRIOV, it would
trigger guest driver load fail with the bare-metal path of the three
features.
