+ 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
