I don't think so; aesthetically I don't like the extra kernel traffic,
but that's not a real concern, and it sounds like that's the correct
approach anyway.

A big reason we submit together on non-DRM is so we can get the kernel
to deal with dependency tracking; if we have proper syncobjs/fences,
that doesn't matter I don't think.

*tries to figure out what the difference between GEM handles and dmabuf
buffers*

As in, syncobjs are within the driver, whereas fences can be shared
across processes/parts of the chip and imported/exported?
