Hi All, While working on a driver, i stumbled up on this question. I have a driver where the driver allocates it's buffers (maybe it's better to term that the hardware requires it that way) in the following fashion: Buffer 1: SG list 1 Buffer 2: SG list 2 Buffer 3: SG list 3 Buffer 4: SG list 4 Buffer 5: SG list 5 Buffer 6: SG list 6 Buffer 7: SG list 7 Buffer 8: SG list 8 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 ? Comments ?
