Hi Yiwei,
I am not sure if you are aware, there is an ongoing RFC on adding drm support in cgroup for the purpose of resource tracking. One of the resource is GPU memory. It's not exactly the same as what you are proposing (it doesn't track API usage, but it tracks the type of GPU memory from kmd perspective) but perhaps it would be of interest to you. There are no consensus on it at this point.
Hi Yiwei,
I'd like to point out an effort to have drivers label BOs for debugging purposes: https://lists.freedesktop.org/archives/dri-devel/2019-October/239727.html
I don't know if it would work, but an obvious idea might be to use those labels for tracking the kinds of buffers - a piece of UAPI which I believe you are still missing.
Thanks, pq
