This parameter can be used to disable or enable the soft lockup detector and the NMI watchdog (i.e. the hard lockup detector) at the same time.
The soft lockup detector and the NMI watchdog can also be disabled or enabled individually, using the soft_watchdog and nmi_watchdog parameters. If the watchdog parameter is read, for example by executing
cat /proc/sys/kernel/watchdog
the output of this command (0 or 1) shows the logical OR of soft_watchdog and nmi_watchdog.
