[AMD Official Use Only]
Here is our hypervisor driver compatibility policy:
- Host.y supports Guest.y-1, Guest.y, Guest.y+1
- Guest.y supported by Host.y-1, Host.y,Host.y+1
Host driver had the feature for gfx9 2 years ago. So, this change meet our
compatibility policy.
Thanks,
Zhigang

I was just about to question the same thing.
It looks really good to me to have that cleaned up, but if this breaks with
older versions of the hypervisor then it is a bit questionable change.
Regards,
Christian.
