   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.

1207          This driver adds watchdog support for the integrated watchdog in the
1208          SuperH processors. If you have one of these processors and wish
1209          to have watchdog support enabled, say Y, otherwise say N.
1210
1211          As a side note, saying Y here will automatically boost HZ to 1000
1212          so that the timer has a chance to clear the overflow counter. On
1213          slower systems (such as the SH-2 and SH-3) this will likely yield
1214          some performance issues. As such, the WDT should be avoided here
1215          unless it is absolutely necessary.
