  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.

 27           If unsure, say N.

 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).

 39 config 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. It's always remotely possible that this process might
 45           get killed. If you say Y here, the watchdog cannot be stopped once
 46           it has been started.
