Can you check and make sure this doesn't break polaris or some other generation?
Do you mean breaking device passthrough or normal operation ? I have a
rx 570,
I can test on that.

Subject: [PATCH] drm/amdgpu: do not disable SMU on vm reboot
For passthrough device, we do baco reset after 1st vm boot so
if we disable SMU on 1st VM shutdown baco reset will fail for
2nd vm boot.
