I'd suggest to move that to the "2d commands" section (which isn't
really "2d" but more "not 3d").

We also need a feature flag signaling support for the new command.

Otherwise this looks ok to me.

Are there any patches and/or attempts to merge/discuss upstream?
Specifically for handling the uuids for dma-bufs in linux (guest side)?
I suspect there will be some discussions on this and having at least
some plan upstream can agree on would be good.

cheers,
