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_CORE 32 bool "WatchDog Timer Driver Core" 33 ---help--- 34 Say Y here if you want to use the new watchdog timer driver core. 35 This driver provides a framework for all watchdog timer drivers 36 and gives them the /dev/watchdog interface (and later also the 37 sysfs interface). 38 39config WATCHDOG_NOWAYOUT 40 bool "Disable watchdog shutdown on close" 41 help 42 The default watchdog behaviour (which you get if you say N here) is 43 to stop the timer if the process managing it closes the file 44 /dev/watchdog.

This 1247 watchdog simply watches your kernel to make sure it doesn't freeze, 1248 and if it does, it reboots your computer after a certain amount of 1249 time. 1250 1251 To compile this driver as a module, choose M here: the 1252 module will be called mixcomwd. 1253 1254 Most people will say N. 1255 1256config WDT 1257 tristate "WDT Watchdog timer" 1258 depends on ISA 1259 ---help--- 1260 If you have a WDT500P or WDT501P watchdog board, say Y here, 1261 otherwise N. It is not possible to probe for this board, which means 1262 that you have to inform the kernel about the IO port and IRQ that 1263 is needed (you can do this via the io and irq parameters) 1264 1265 To compile this driver as a module, choose M here: the 1266 module will be called wdt. 1267 1268# 1269# PCI-based Watchdog Cards 1270# 1271 1272comment "PCI-based Watchdog Cards" 1273 depends on PCI 1274 1275config PCIPCWATCHDOG 1276 tristate "Berkshire Products PCI-PC Watchdog" 1277 depends on PCI 1278 ---help--- 1279 This is the driver for the Berkshire Products PCI-PC Watchdog card. 1280 This card simply watches your kernel to make sure it doesn't freeze, 1281 and if it does, it reboots your computer after a certain amount of 1282 time.
