This parameter can be used to control the soft lockup detector.
The soft lockup detector monitors CPUs for threads that are hogging the CPUs without rescheduling voluntarily, and thus prevent the ‘watchdog/N’ threads from running. The mechanism depends on the CPUs ability to respond to timer interrupts which are needed for the ‘watchdog/N’ threads to be woken up by the watchdog timer function, otherwise the NMI watchdog - if enabled - can detect a hard lockup condition.
