   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.

  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).

  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".

 808           It may well work with other cards.  It reads port 0x443 to enable
 809           and re-set the watchdog timer, and reads port 0x45 to disable
 810           the watchdog.  If you have a card that behave in similar ways,
