Hi,
Xenomai will use a timer only if it has not been shutdown by Linux. So,
if enabling the PM_TIMER causes the APIC to be shut down then yes, you
should disable PM_TIMER. Though with CONFIG_SMP, there is one LAPIC
timer whereas there is only one PM_TIMER.
What is the result of cat /proc/timer_list when the APIC was disabled?
Regards.
