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).
