  8         ---help---
  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.
 21 
 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
 26           table is full.

 28           If unsure, say N.

 34         ---help---
 35           Say Y here if you want to use the new 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
 38           sysfs interface).
 39 
 40 config WATCHDOG_NOWAYOUT
 41         bool "Disable watchdog shutdown on close"
 42         help
 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
 47           it has been started.

807           The TCO (Total Cost of Ownership) timer is a watchdog timer
808           that will reboot the machine after its second expiration. The
809           expiration time can be configured with the "heartbeat" parameter.
810 
811           On some motherboards the driver may fail to reset the chipset's
812           NO_REBOOT flag which prevents the watchdog from rebooting the

1549           This is the driver for the Berkshire Products PCI-PC Watchdog card.
1550           This card simply watches your kernel to make sure it doesn't freeze,
1551           and if it does, it reboots your computer after a certain amount of
1552           time. The card can also monitor the internal temperature of the PC.
1553           More info is available at <http://www.berkprod.com/pci_pc_watchdog.htm>.
1554 
1555           To compile this driver as a module, choose M here: the
1556           module will be called pcwd_pci.
1557 
1558           Most people will say N.

1564           If you have a PCI-WDT500/501 watchdog board, say Y here, otherwise N.
1565 
1566           If you have a PCI-WDT501 watchdog board then you can enable the
1567           temperature sensor by setting the type parameter to 501.
1568 
1569           If you want to enable the Fan Tachometer on the PCI-WDT501, then you
1570           can do this via the tachometer parameter. Only do this if you have a
1571           fan tachometer actually set up.
1572 
1573           To compile this driver as a module, choose M here: the
1574           module will be called wdt_pci.
