Re: reserving VRAM for page tables

Yeah, but we should try to unify the memory management.

I mean we must have a common rational on how much memory page tables are going to use.

If we allow applications to oversubscribe or not is a completely different topic.

I don't think this should go into amdgpu_vram_mgr. KFD tries to avoid running out of VRAM for page tables because we cannot oversubscribe memory within a process and we want to avoid compute processes evicting each other because that would mean thrashing. Those limitation don't apply to graphics contexts.

Hi guys,

I've seen some patches flying by to change how much VRAM is reserved for page tables in the KFD.

Would it make sense to fully move that into amdgpu_vram_mgr.c?

Christian.
