--- Comment #17 from Nicolas Dufresne (stormer) <nicolas.dufresne at collabora.co.uk> ---
So far, we went forward without the memory:DMABuf feature, as we could not
agree on the design of it. It was always filled with ambiguities.

glupload implements DMABuf importation without any needs for negotiation. This
is done by simply inspecting the incoming memories. For a sink like this one,
there is only 3 case so it's rather simple.
  - The buffer you received is one from a pool you proposed (just use it)
  - The buffer you received is a DMABuf (try to prime it)
  - None of the above, of PRIME failed, just copy
