1# 2# Watchdog device configuration 3# 4 5menuconfig WATCHDOG 6 bool "Watchdog Timer Support" 7 ---help--- 8 If you say Y here (and to one of the following options) and create a 9 character special file /dev/watchdog with major number 10 and minor 10 number 130 using mknod ("man mknod"), you will get a watchdog, i.e.: 11 subsequently opening the file and then failing to write to it for 12 longer than 1 minute will result in rebooting the machine. This 13 could be useful for a networked machine that needs to come back 14 on-line as fast as possible after a lock-up. There's both a watchdog 15 implementation entirely in software (which can sometimes fail to 16 reboot the machine) and a driver for hardware watchdog boards, which 17 are more robust and can also keep track of the temperature inside 18 your computer. For details, read 19 <file:Documentation/watchdog/watchdog-api.txt> in the kernel source. 20 21 The watchdog is usually used together with the watchdog daemon 22 which is available from 23 <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can 24 also monitor NFS connections and can reboot the machine when the process 25 table is full. 26 27 If unsure, say N. 28 29if WATCHDOG 30 31config WATCHDOG_NOWAYOUT 32 bool "Disable watchdog shutdown on close" 33 help 34 The default watchdog behaviour (which you get if you say N here) is 35 to stop the timer if the process managing it closes the file 36 /dev/watchdog. It's always remotely possible that this process might 37 get killed. If you say Y here, the watchdog cannot be stopped once 38 it has been started. 39 40# 41# General Watchdog drivers 42# 43 44comment "Watchdog Device Drivers" 45 46# Architecture Independent 47 48config SOFT_WATCHDOG 49 tristate "Software watchdog" 50 help 51 A software monitoring watchdog.
