Hi, If my application allocate memory for input and output buffers, and pass the pointer to a kernel driver (via v4l2 queue buffer operation), can the kernel driver access it? Do I need to setup DMA before teh kernel driver can read/write to it? Thank you. _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
