Hi Hans,

There is one thing to be wary of. Some of the hardware, like s5p-mfc,
require all the buffers to be registered before streaming. That's not
possible with DMABUF memory type, because the buffers are known only
after respective QBUF calls and also subsequent QBUF calls with the
same buffer index may queue different DMA-bufs. Care must be taken not
to enable DMABUF for such hardware.
Best regards,
Tomasz

Hi Hans,
Thank you for the patch.

If we want to enable DMABUF support unconditionally (or nearly, se
Tomasz' reply), wouldn't it make more sense to drop the VB2_DMABUF flag
from drivers and set it in vb2 ? We could add a VB2_NO_DMABUF for the
odd cases. We could do the same for VB2_MMAP. It would make driver code
simpler.
