config WATCHDOG
	bool "Watchdog Timer Support"
	---help---
	  If you say Y here (and to one of the following options) and create a
	  character special file /dev/watchdog with major number 10 and minor
	  number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
	  subsequently opening the file and then failing to write to it for
	  longer than 1 minute will result in rebooting the machine. This
	  could be useful for a networked machine that needs to come back
	  on-line as fast as possible after a lock-up. There's both a watchdog
	  implementation entirely in software (which can sometimes fail to
	  reboot the machine) and a driver for hardware watchdog boards, which
	  are more robust and can also keep track of the temperature inside
	  your computer. For details, read <file:Documentation/watchdog/watchdog.txt>
	  in the kernel source.

	  The watchdog is usually used together with the watchdog daemon
	  which is available from
	  <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
	  also monitor NFS connections and can reboot the machine when the process
	  table is full.

	  If unsure, say N.

config WATCHDOG_NOWAYOUT
	bool "Disable watchdog shutdown on close"
	depends on WATCHDOG
	help
	  The default watchdog behaviour (which you get if you say N here) is
	  to stop the timer if the process managing it closes the file
	  /dev/watchdog. It's always remotely possible that this process might
	  get killed. If you say Y here, the watchdog cannot be stopped once
	  it has been started.

config SOFT_WATCHDOG
	tristate "Software watchdog"
	depends on WATCHDOG
	help
	  A software monitoring watchdog. This will fail to reboot your system
	  from some situations that the hardware watchdog will recover
	  from. Equally it's a lot cheaper to install.

	  To compile this driver as a module, choose M here: the
	  module will be called softdog.

	help
	  The Intel Footbridge chip contains a built-in watchdog circuit. Say Y
	  here if you wish to use this. Alternatively say M to compile the
	  driver as a module, which will be called wdt285.

	  This driver does not work on all machines. In particular, early CATS
	  boards have hardware problems that will cause the machine to simply
	  lock up if the watchdog fires.

	  "If in doubt, leave it out" - say N.

	  Note: The internal IXP4xx watchdog does a soft CPU reset
	  which doesn't reset any peripherals. There are circumstances
	  where the watchdog will fail to reset the board correctly
	  (e.g., if the boot ROM is in an unreadable state).

	help
	  Watchdog timer block in the Samsung S3C2410 chips. This will
	  reboot the system when the timer expires with the watchdog
	  enabled.

	  The driver is limited by the speed of the system's PCLK
	  signal, so with reasonably fast systems (PCLK around 50-66MHz)
	  then watchdog intervals of over approximately 20seconds are

	  This watchdog simply watches your kernel to make sure it doesn't
	  freeze, and if it does, it reboots your computer after a certain

	  Hardware driver for the TCO timer built into the Intel 82801
	  I/O Controller Hub family.  The TCO (Total Cost of Ownership)
	  timer is a watchdog timer that will reboot the machine after
	  its second expiration. The expiration time can be configured
	  with the "heartbeat" parameter.

	  On some motherboards the driver may fail to reset the chipset's
	  NO_REBOOT flag which prevents the watchdog from rebooting the
	  machine. If this is the case you will get a kernel message like
	  "failed to reset NO_REBOOT flag, reboot disabled by hardware".

	  To compile this driver as a module, choose M here: the

	help
	  This driver can be used with the watchdog timer found on some

	  It may well work with other cards.  It reads port 0x443 to enable
	  and re-set the watchdog timer, and reads port 0x45 to disable
	  the watchdog.  If you have a card that behave in similar ways,
	  you can probably make this driver work with your card as well.

	  *Note*: This hardware watchdog is not probeable and thus there
	  is no way to know if writing to its IO address will corrupt
	  your system or have any real effect.  The only way to be sure
	  that this driver does what you want is to make sure you
	  are running it on an EPX-C3 from Winsystems with the watchdog
	  timer at IO address 0x1ee and 0x1ef.  It will write to both those
	  IO ports.  Basically, the assumption is made that if you compile
	  this driver into your kernel and/or load it as a module, that you
	  know what you are doing and that you are in fact running on an

	  you a thermometer inside your computer: reading from
	  /dev/temperature yields one byte, the temperature in degrees
	  Fahrenheit. This works only if you have a WDT501P watchdog board
	  installed.

	  If you want to enable the Fan Tachometer on the WDT501P, then you
	  can do this via the tachometer parameter. Only do this if you have a
	  fan tachometer actually set up.

	  This is the driver for the Berkshire Products PCI-PC Watchdog card.
	  This card simply watches your kernel to make sure it doesn't freeze,
	  and if it does, it reboots your computer after a certain amount of
	  time. The card can also monitor the internal temperature of the PC.
	  More info is available at <http://www.berkprod.com/pci_pc_watchdog.htm>.

	  To compile this driver as a module, choose M here: the
	  module will be called pcwd_pci.

	  Most people will say N.

	  If you have a PCI-WDT500/501 watchdog board, say Y here, otherwise N.

	  Saying Y here and creating a character special file /dev/temperature
	  with major number 10 and minor number 131 ("man mknod") will give
	  you a thermometer inside your computer: reading from
	  /dev/temperature yields one byte, the temperature in degrees
	  Fahrenheit. This works only if you have a PCI-WDT501 watchdog board
	  installed.

	  If you want to enable the Fan Tachometer on the PCI-WDT501, then you
