DMA: user-space (system calls) and RTAI

["daniel sheltraw" <l5gibson@hotmail.com>]

Hello RTAIers

Can anyone tell me about DMA under RTAI. Are then any routines
available for setting up DMA transfers under RTAI. Can you setup
DMA using an API (called from user-space) for the hardware (example: OSS for 
recorded sound playback) and then do the final register
writes to start the actual transfer from within RTAI.
If this is at least possible in principle please let me know what you think 
so that I can look more closely at writing code to do so.

Thanks,
Daniel
