I think I did not tell it clearly: I want to replace a running Xenomai/RTNET approach by completely using the RT_PREEMPT patch. I do not want to do any mix of Xenomai and = RT_PREEMPT. The target is to have a RT_PREEMPT only system that performs similar to= the Xenomai/rtnet approach. Sorry for any confusion here... Thus, the concrete question (in short) is: - Which (user/kernel) threads (prio, affinity) are relevant for using E= thernet (UDP/IP) communication with the RT_PREEMPT patch. > I think you have a point it certainly needs to be checked whether > the RT_PREEMPT patch behaves with an package like Xenomai. > My initial reaction is just that in the case of Xenomai, it just appl= ies > an Hard Real time constraint on the RT_PREEMPT patch. >=20 > But it is certainly much better to investigate what happens when we > have an Xenomai like RT System behave otherwise.
