+	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-api.rst> 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_CORE
+	tristate "WatchDog Timer Driver Core"
+	help
+	  Say Y here if you want to use the new watchdog timer driver core.
+	  This driver provides a framework for all watchdog timer drivers
+	  and gives them the /dev/watchdog interface (and later also the
+	  sysfs interface).
+
+config WATCHDOG_NOWAYOUT
+	bool "Disable watchdog shutdown on close"
+	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 WATCHDOG_HANDLE_BOOT_ENABLED
+	bool "Update boot-enabled watchdog until userspace takes over"
+	default y
+	help
+	  The default watchdog behaviour (which you get if you say Y here) is
+	  to ping watchdog devices that were enabled before the driver has
+	  been loaded until control is taken over from userspace using the
+	  /dev/watchdog file. If you say N here, the kernel will not update
+	  the watchdog on its own. Thus if your userspace does not start fast
+	  enough your device will reboot.
+
+config WATCHDOG_OPEN_TIMEOUT
+	int "Timeout value for opening watchdog device"
+	default 0
+	help
+	  The maximum time, in seconds, for which the watchdog framework takes
+	  care of pinging a hardware watchdog.  A value of 0 means infinite. The
+	  value set here can be overridden by the commandline parameter
+	  "watchdog.open_timeout".

+	  to have watchdog support enabled, say Y, otherwise say N.
+
+	  As a side note, saying Y here will automatically boost HZ to 1000
+	  so that the timer has a chance to clear the overflow counter. On
