I just recognized that "top" doesn't start if the RTDM demo http://www.captain.at/xenomai-real-time-driver-example.php runs. => "user" runs, "top" is started: "top" doesn't start as long as "user" is running. When "user" is terminated, "top" displays the ncurses screen. xeno-2.1-rc3 K2.6.15 Anyone got an idea ? Thanks & best regards, Hannes. ^ permalink raw reply [flat|nested] 2+ messages in thread

That's because you grab the standard timer but do not propagate it to Linux (all timed activity of Linux freezes, not just top). Moreover, this demo only works in case Xenomai is using the APIC timer. Otherwise, that IRQ is blocked for RT drivers (Dmitry's shared IRQ patch is not yet merged).
