Hi,
     I wonder that whether the xenomai regular thread whose schedule policy
is *SCHED_OTHER* *has more opportunities to occupy the cpu resources*
then the normal linux thread which managed by linux?
     Even if the linux thread with *SCHED_FIFO * schedule policy?

Yes, that happens for Xenomai-attached thread when they enter the real-time domain, e.g. while holding a Xenomai lock. At that point, they are above any regular Linux thread by nature - because they have to in order to not break the scheduling requirements of the RT domain.
