Yes, agreed. My idea with exposing vram sections using numa nodes
to reuse all the existing allocation policies directly, those won't work.
So at boot-up your default numa policy would exclude any vram nodes.
But I think (as an -mm layman) that numa gives us a lot of the tools and
policy interface that we need to implement what we want for gpus.
Are you suggesting creating NUMA nodes for video RAM (I assume that's
what you mean by vram) where that RAM is not at all CPU-accessible?
