        Enabling this option allows the NMI watchdog to be used in order
        to debug abnormal (timer) interrupt latencies.

        The NMI watchog is programmed in order to expire a certain time 
        after the currently awaited timer shot, and triggers if the shot 
        did not happen as expected. This allowed amount of jitter is 
        configurable. When triggered, the NMI watchdog prints the call
        stack and causes a kernel panic, which should hopefully allow to
        find out why the timer got delayed.

        This option is mainly useful for debugging Xenomai internals, and 
        not meant for debugging applications.

config XENO_HW_NMI_DEBUG_LATENCY_MAX
        depends XENO_HW_NMI_DEBUG_LATENCY
        int "NMI watchdog latency threshold (us)"
        default 100
        help
        When the timer interrupt latency goes above this threshold, the
        NMI watchdog pulls the handbrake.
