Subject: [PATCH AUTOSEL 5.15 6/6] drm/amdkfd: ignore crat by default
From: Alex Deucher <[email protected]>
[ Upstream commit a6dea2d64ff92851e68cd4e20a35f6534286e016 ]
We are dropping the IOMMUv2 path, so no need to enable this.
It's often buggy on consumer platforms anyway.
This is not needed for stable.
I agree. I was about to comment in the 5.10 patch as well.
Regards,
Felix
Alex
