Hello, I am beginner with RT patch, and cyclictest. I have installed ubuntu 12.04 lts, and used the binary of 3.18 kernel from: https://bitbucket.org/thismaechler/ubuntustudio-14.04-realtimeaudio/src/65ac2d9fce70f63479ef4a8f4764743cc7dc9b11/rt-kernel/HOWTO?at=master&fileviewer=file-view-default I have verified with uname -a that it is linux-rt version. I then tested with cyclictest , for interval of 1msec (1000usec) cyclictest -t1 -p 80 -n -i 1000 -l 10000 and got max value of 180usec. On comparing my results to resuls examples given in https://rt.wiki.kernel.org/index.php/Cyclictest it seems like a very large number. I know it depends on hardware (I am using Atom, one core only.), yet becuase I'm not too experienced with it, I am not sure if my real problem is HW or doing wrong testing/RTpatch. I also see that it is much better then results before applying RT patch (3000usec) Another thing is that I also noticed that cpu load of 100% gives same max value as if I just interrupt the console with several enter clicks, from this I assume that load of 50% will probably won't change this max value to a lower one.
