My initial reaction is just that in the case of Xenomai, it just applie= s an Hard Real time constraint on the RT_PREEMPT patch. But it is certainly much better to investigate what happens when we have an Xenomai like RT System behave otherwise. Does it change the RT_PREEMPT patch. On Thu, Apr 30, 2009 at 4:11 PM, M.
