7 bool "Watchdog Timer Support"
9 If you say Y here (and to one of the following options) and create a
10 character special file /dev/watchdog with major number 10 and minor
11 number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
12 subsequently opening the file and then failing to write to it for
13 longer than 1 minute will result in rebooting the machine. 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.
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
33 bool "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
40 config WATCHDOG_NOWAYOUT
41 bool "Disable watchdog shutdown on close"
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. It's always remotely possible that this process might
46 get killed. If you say Y here, the watchdog cannot be stopped once
49 config WATCHDOG_HANDLE_BOOT_ENABLED
50 bool "Update boot-enabled watchdog until userspace takes over"
53 The default watchdog behaviour (which you get if you say Y here) is
54 to ping watchdog devices that were enabled before the driver has
55 been loaded until control is taken over from userspace using the
56 /dev/watchdog file. If you say N here, the kernel will not update
57 the watchdog on its own. Thus if your userspace does not start fast
58 enough your device will reboot.
