  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.

 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.

778           Hardware driver for the TCO timer built into the nVidia Hub family
779           (such as the MCP51).  The TCO (Total Cost of Ownership) timer is a
780           watchdog timer that will reboot the machine after its second
781           expiration. The expiration time can be configured with the
782           "heartbeat" parameter.
783 
784           On some motherboards the driver may fail to reset the chipset's
785           NO_REBOOT flag which prevents the watchdog from rebooting the
786           machine. If this is the case you will get a kernel message like
787           "failed to reset NO_REBOOT flag, reboot disabled by hardware".
