What you mean to say is the pthread library. http://en.wikipedia.org/wiki/POSIX_Threads http://www.net.t-labs.tu-berlin.de/~gregor/tools/pthread-scheduling.html How will you replace Xenomai/RTNET Completely. You don't even know how it behaves with RT_PREEMPT patch. Also why do you think it necessary to have an common guide line on Priorities on thread's. I dont think they follow any standard on this regard. For Example QT might be following some other Thread Priority standard in regards to number of levels, thread nomenclature etc. > Sorry for any confusion here... > > Thus, the concrete question (in short) is: > - Which (user/kernel) threads (prio, affinity) are relevant for using Ethernet (UDP/IP) communication > with the RT_PREEMPT patch. you could look up these articles. based on what i have discussed. http://lists.trolltech.com/qt-interest/2007-05/thread00746-0.html On Thu, Apr 30, 2009 at 4:47 PM, M.
