V4L/DVB: [v5,2/2] v4l: Add a mem-to-mem videobuf framework test device (96d8eab5) · Commits · 戴 / test

This is a virtual device driver for testing the memory-to-memory framework. This virtual device uses in-memory buffers for both its source and destination. It is capable of multi-instance, multi-buffer-per-transaction operation (via the mem2mem framework). [mchehab@redhat.com: use videobuf_queue_to_vaddr instead of the removed videobuf_queue_to_vmalloc] Signed-off-by:
