Newbie here investigating whether we can use Xenomai.  Looking good so
far, but I am wondering whether we will be able to use our PowerDAQ
PD2-MF-16-150/16H board.  It comes with drivers for RTLinux and RTAI
(I think with complete sources), does that do us any good for use with
Xenomai?

Thanks,

-kb

Depends. Is that driver based on Comedi?

If so, the usage depends on the availability of Comedi under Xenomai.
This is not yet ported, but I'm currently trying to trigger a discussion
with the Comedi maintainers about a port of their project's real-time
subsystem over the generic driver layer RTDM. This step would provide
immediate support for all recent real-time Linux variants, from Xenomai
over RTAI 3.3 and, on the mid-term, even to RTLinux/GPL (they also plan
to adopt RTDM). Anyway, I cannot say yet if and when this port will be done.

If your driver is stand-alone at least for one of both supported
real-time Linux versions, then it should already be possible to port it
over a similar API skin of Xenomai (native for RTAI, POSIX for RTLinux).
This is not the preferred way (RTDM / Comedi would be cleaner), but it
is a pragmatic one.

Well, with the sources available and if the programming model of the
hardware is not complicated, you can still try to develop your own
specific interface - option three...
