I notice about 8% cpu usage if I call rt_timer_set_mode(125000); and load up a couple of tasks which do nothing but block on conditional variables. (The tasks are using 0%.) I didn't have this issue (as far as I know) with RTAI, and I didn't have this issue when using aperiodic timing mode. What I need is to have all my tasks locked to some timebase, and was told in a previous discussion that this was the way to go.
Is there any reason it should use so much CPU time? Thanks, Steven
