1. share buffer from intel -> nouveau.
2. share buffer from nouveau -> intel
3. share intel->nouveau, map on both, write intel, read nouveau
4. share intel->nouveau, blit intel fill, readback on nouveau
test 1 + map buffer, read/write, map other size.
do some hw actions on the buffer
some illegal operations -
close prime fd try and map
