   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).
  38
  39config 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.

1234          to have watchdog support enabled, say Y, otherwise say N.
1235
1236          As a side note, saying Y here will automatically boost HZ to 1000
1237          so that the timer has a chance to clear the overflow counter. On
1238          slower systems (such as the SH-2 and SH-3) this will likely yield
1239          some performance issues. As such, the WDT should be avoided here
