   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
  39 config 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.

 787           This driver can be used with the watchdog timer found on some
 788           single board computers, namely the 6010 PII based computer.
 789           It may well work with other cards.  It reads port 0x443 to enable
 790           and re-set the watchdog timer, and reads port 0x45 to disable
 791           the watchdog.  If you have a card that behave in similar ways,
 792           you can probably make this driver work with your card as well.

1158           This driver is for a SoC level watchdog that exists on some
1159           Freescale PowerPC processors. So far this driver supports:
1160           - MPC8xx watchdogs
1161           - MPC83xx watchdogs
1162           - MPC86xx watchdogs
1163
1164           For BookE processors (MPC85xx) use the BOOKE_WDT driver instead.

1253
1254           As a side note, saying Y here will automatically boost HZ to 1000
1255           so that the timer has a chance to clear the overflow counter. On
1256           slower systems (such as the SH-2 and SH-3) this will likely yield
1257           some performance issues. As such, the WDT should be avoided here
