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
