Hi all,

Is it possible to run, or perhaps build Xenomai/SOLO to run without 
superuser privileges?  I don't need real-time performance guarantees for 
this particular application.

Thanks,
Mike Buksas

No, this won't work. The entire emulation engine assumes that your
threads may be given different static priorities above 0; the current
implementation won't work with SCHED_OTHER threads. Besides, this does
not make much sense to emulate a priority-based scheduler without any
consideration for priority levels.

/etc/security/limits.conf may help to allow selected non-root users to
gain RT priority.
