This 14 could be useful for a networked machine that needs to come back 15 on-line as fast as possible after a lock-up. There's both a watchdog 16 implementation entirely in software (which can sometimes fail to 17 reboot the machine) and a driver for hardware watchdog boards, which 18 are more robust and can also keep track of the temperature inside 19 your computer. For details, read 20 <file:Documentation/watchdog/watchdog-api.txt> in the kernel source. 21 22 The watchdog is usually used together with the watchdog daemon 23 which is available from 24 <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can 25 also monitor NFS connections and can reboot the machine when the process 26 table is full. 27 28 If unsure, say N. 29 30if WATCHDOG 31 32config WATCHDOG_CORE 33 bool "WatchDog Timer Driver Core" 34 ---help--- 35 Say Y here if you want to use the new watchdog timer driver core. 36 This driver provides a framework for all watchdog timer drivers 37 and gives them the /dev/watchdog interface (and later also the 38 sysfs interface). 39 40config WATCHDOG_NOWAYOUT 41 bool "Disable watchdog shutdown on close" 42 help 43 The default watchdog behaviour (which you get if you say N here) is 44 to stop the timer if the process managing it closes the file 45 /dev/watchdog.

If you say N here, the kernel will not update 57 the watchdog on its own.
