Now, on each video interrupt, I know which SG list i need to read from. At this stage i do need to copy the buffers associated with each of the SG lists at once. In this scenario, I don't see how videobuf could be used, while I keep getting this feeling that a simple copy_to_user of the entire buffer could do the whole job in a better way, since the buffers themselves are already managed and initialized already. Am I correct in thinking so, or is it that I am overlooking something ?
How to activate DMA transfers only if there is empty space for the DMA transfer?
