Hi Wen, If you're bound to use that kernel version, then one option to consider might be backporting the videobuf2 to that kernel. 2.6.35 isn't so old. You'd save work by not implementing the buffer handling on your own AND also, you wouldn't later need to port the driver to use videobuf2. I would suggest not to start using the old videobuf at this point. With the current ISPs with their own MMUs it really does more harm than good.
