C++ (Cpp) cpu_nmi_callback Examples

Example #1

File: nmi.c Project: caobosco/libxlPVUSB

int __init watchdog_setup(void)
{
    unsigned int cpu;

    /*
     * Activate periodic heartbeats. We cannot do this earlier during 
     * setup because the timer infrastructure is not available.
     */
    for_each_online_cpu ( cpu )
        cpu_nmi_callback(&cpu_nmi_nfb, CPU_UP_PREPARE, (void *)(long)cpu);
    register_cpu_notifier(&cpu_nmi_nfb);

    watchdog_enable();
    return 0;
}

Example #2
