This 15 could be useful for a networked machine that needs to come back 16 on-line as fast as possible after a lock-up. There's both a watchdog 17 implementation entirely in software (which can sometimes fail to 18 reboot the machine) and a driver for hardware watchdog boards, which 19 are more robust and can also keep track of the temperature inside 20 your computer. For details, read 21 <file:Documentation/watchdog/watchdog-api.txt> in the kernel source. 22 23 The watchdog is usually used together with the watchdog daemon 24 which is available from 25 <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can 26 also monitor NFS connections and can reboot the machine when the process 27 table is full. 28 29 If unsure, say N. 30 31if WATCHDOG 32 33config WATCHDOG_CORE 34 tristate "WatchDog Timer Driver Core" 35 ---help--- 36 Say Y here if you want to use the new watchdog timer driver core. 37 This driver provides a framework for all watchdog timer drivers 38 and gives them the /dev/watchdog interface (and later also the 39 sysfs interface). 40 41config WATCHDOG_NOWAYOUT 42 bool "Disable watchdog shutdown on close" 43 help 44 The default watchdog behaviour (which you get if you say N here) is 45 to stop the timer if the process managing it closes the file 46 /dev/watchdog.
