I've added documentation for each call, and integrated the renaming from drm cgroup to dev cgroup, based on maxime ripard's work. Maxime has been testing this with dma-buf heaps and v4l2 too, and it seems to work. In the initial submission, I've decided to only add the smallest enablement possible, to have less chance of breaking things. The API has been changed slightly, from "$name region.$regionname=$limit" in a file called dev.min/low/max to "$subsystem/$name $regionname=$limit" in a file called dev.region.min/low/max. This hopefully allows us to perhaps extend the API later on with the possibility to set scheduler weights on the device, like in https://blogs.igalia.com/tursulin/drm-scheduling-cgroup-controller/ Maarten Lankhorst (5): kernel/cgroup: Add "dev" memory accounting cgroup drm/ttm: Handle cgroup based eviction in TTM drm/xe: Implement cgroup for vram drm/amdgpu: Add cgroups implementation [HACK] drm/xe: Hack to test with mapped pages instead of vram.
