Thanks for adding DMABUF support to vivi.
What would be great is if DMABUF support is also added to mem2mem_testdev.
It would make an excellent test case to take the vivi output, pass it
through mem2mem_testdev, and finally output the image using the gpu, all
using dmabuf.
It's also very useful for application developers to test dmabuf support
without requiring special hardware (other than a dmabuf-enabled gpu
driver).
