Hi!

I'm porting a driver to RTAI, using RTDM. The original driver uses
Workqueues to process the data received by the interrupt handler. What
method does RTDM in a this situation?


Thanks for your replies

RTDM doesn't provide an explicit queuing API, you may design a specific
one for your scenario (or keep the original one if it was not
RTAI-specific). What RTDM offers is locking (rtdm_lock_xxx) and
signalling (rtdm_event_xxx or rtdm_sem_xxx).

Patterns can be found e.g. in the serial driver (ring buffer with
rtdm_event) or in RTnet (packet queue with rtdm_event or rtdm_sem).
