Subject: [Xenomai-core] False positive XENO_BUGON(NUCLEUS, need_resched == 0)?
Date: Fri, 27 Aug 2010 11:22:17 +0200	[thread overview]
Message-ID: <4C7783C9.5090501@domain.hid> (raw)

Hi,

I'm hitting that bug check in __xnpod_schedule after
xnintr_clock_handler issued a xnpod_schedule like this:

	if (--sched->inesting == 0) {
		__clrbits(sched->status, XNINIRQ);
		xnpod_schedule();
	}

Either the assumption behind the bug check is no longer correct (no call
to xnpod_schedule() without a real need), or we should check for
__xnpod_test_resched(sched) in xnintr_clock_handler (but under nklock then).

Comments?
