   7         bool "Watchdog Timer Support"
   8         ---help---
   9           If you say Y here (and to one of the following options) and create a
  10           character special file /dev/watchdog with major number 10 and minor
  11           number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
  12           subsequently opening the file and then failing to write to it for
  13           longer than 1 minute will result in rebooting the machine. This
  14           could be useful for a networked machine that needs to come back
  15           on-line as fast as possible after a lock-up. There's both a watchdog
  16           implementation entirely in software (which can sometimes fail to
  17           reboot the machine) and a driver for hardware watchdog boards, which
  18           are more robust and can also keep track of the temperature inside
  19           your computer. For details, read
  20           <file:Documentation/watchdog/watchdog-api.txt> in the kernel source.
  21
  22           The watchdog is usually used together with the watchdog daemon
  23           which is available from
  24           <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
  25           also monitor NFS connections and can reboot the machine when the process
  26           table is full.
  27
  28           If unsure, say N.

  35           Say Y here if you want to use the new watchdog timer driver core.
  36           This driver provides a framework for all watchdog timer drivers

  43           The default watchdog behaviour (which you get if you say N here) is
  44           to stop the timer if the process managing it closes the file
  45           /dev/watchdog. It's always remotely possible that this process might
  46           get killed. If you say Y here, the watchdog cannot be stopped once
  47           it has been started.

1202           is no way to know if writing to its IO address will corrupt
1203           your system or have any real effect.  The only way to be sure
1204           that this driver does what you want is to make sure you
1205           are running it on an EPX-C3 from Winsystems with the watchdog
1206           timer at IO address 0x1ee and 0x1ef.  It will write to both those
1207           IO ports.  Basically, the assumption is made that if you compile
1208           this driver into your kernel and/or load it as a module, that you

1595           This is the driver for the Berkshire Products ISA-PC Watchdog card.
1596           This card simply watches your kernel to make sure it doesn't freeze,
1597           and if it does, it reboots your computer after a certain amount of
1598           time. This driver is like the WDT501 driver but for different
1599           hardware. Please read <file:Documentation/watchdog/pcwd-watchdog.txt>. The PC
1600           watchdog cards can be ordered from <http://www.berkprod.com/>.

1626           otherwise N. It is not possible to probe for this board, which means
1627           that you have to inform the kernel about the IO port and IRQ that
1628           is needed (you can do this via the io and irq parameters)

1660
1661           If you have a PCI-WDT501 watchdog board then you can enable the
1662           temperature sensor by setting the type parameter to 501.
1663
1664           If you want to enable the Fan Tachometer on the PCI-WDT501, then you
1665           can do this via the tachometer parameter. Only do this if you have a
1666           fan tachometer actually set up.
