Since the buffer was allocated in user space, it is virtual contiguous but not physically contiguous, hence the need for a list of physical addresses. To the hardware, the buffer appears as a collection of scattered buffers. Hence, scatter/gather. Like I said, I haven't look at the ALSA API for S/G, so I may be talking about an implementation of S/G that does not apply to ALSA. -- Timur Tabi Linux Kernel Developer @ Freescale _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
