no code is needed to implement support for this. its handled by the ALSA mid-level layer. its possible that your driver has set or has not set some flag related to this, making the mid-level code think its not possible to do it. >> Implementing memory-mapped IO isn't exactly what you do in a day. >> jackit.sf.net or the shortly-to-be-released library I'm working on >> will do it for you.
