Do you observe the same problem with xenomai "latency" test? If yes, then using the I-pipe tracer should help you. Note that all that is documented in the "troubleshooting" guide: http://xenomai.org/troubleshooting-a-dual-kernel-configuration/#the_latency_test_shows_high_latencies -- Gilles. https://click-hack.org _______________________________________________ Xenomai mailing list [email protected] http://xenomai.org/mailman/listinfo/xenomai
