Hello Remy, I tried today Xenomai (2.6.20.21 kernel, that is the last supported by I-Pipe patch), the same example program (recompiled with Xenomai libpthread_rt). Results are a little bit better (worst-case latency is around 150us). Using Xenomai in native skin (as kernel module) produces much better results (worst-case latency is around 50us). Currently, I am looking for the best way to "transfer" application to user land/posix. > FWIW: For getting the most accurate realtime response for periodic > timers, I used a TC block to generate a periodic interrupt, that only > needs to wake up a RT-thread.

May you give me a bit more details on this? Thanks :) Cheers! -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
