- * A Watchdog Timer (WDT) is a hardware circuit that can
- * reset the computer system in case of a software fault.

*
- * Usually a userspace daemon will notify the kernel WDT driver
- * via the /dev/watchdog special device file that userspace is
- * still alive, at regular intervals. When such a notification
- * occurs, the driver will usually tell the hardware watchdog
- * that everything is in order, and that the watchdog should wait
- * for yet another little while to reset the system.
- * If userspace fails (RAM error, kernel bug, whatever), the
- * notifications cease to occur, and the hardware watchdog will
- * reset the system (causing a reboot) after the timeout occurs.
