11 character special file /dev/watchdog with major number 10 and minor
12 number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:

23 The watchdog is usually used together with the watchdog daemon
24 which is available from
25 <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
26 also monitor NFS connections and can reboot the machine when the process

372 ARM SBSA Generic Watchdog has two stage timeouts:
373 the first signal (WS0) is for alerting the system by interrupt,
374 the second one (WS1) is a real hardware reset.
375 More details: ARM DEN0029B - Server Base System Architecture (SBSA)
376
377 This driver can operate ARM SBSA Generic Watchdog as a single stage
378 or a two stages watchdog, it depends on the module parameter "action".
379
380 Note: the maximum timeout in the two stages mode is half of that in
381 the single stage mode.

383 To compile this driver as module, choose M here: The module
384 will be called sbsa_gwdt.

1137 It`s possible to enable watchdog timer either from BIOS (F2) or from booted Linux.
1138 When "Watchdog Timer Value" enabled one can set 31-255 s operational range.
1139
1140 Entering BIOS setup temporary disables watchdog operation regardless to current state,
1141 so system will not be restarted while user in BIOS setup.
1142
1143 Once watchdog was enabled the system will be restarted every
1144 "Watchdog Timer Value" period, so to prevent it user can restart or
1145 disable the watchdog.

1743 Hardware driver for OCTEON's on chip watchdog timer.
1744 Enables the watchdog for all cores running Linux. It
1745 installs a NMI handler and pokes the watchdog based on an
1746 interrupt. On first expiration of the watchdog, the
1747 interrupt handler pokes it. The second expiration causes an
1748 NMI that prints a message. The third expiration causes a
1749 global soft reset.
1750

1752 from the first interrupt, it is then only poked when the
1753 device is written.

1935 Select the default watchdog timer period to be used by the PowerPC
1936 Book-E watchdog driver. A watchdog "event" occurs when the bit
1937 position represented by this number transitions from zero to one.
1938
1939 For Freescale Book-E processors, this is a number between 0 and 63.
1940 For other Book-E processors, this is a number between 0 and 3.

1993 to have watchdog support enabled, say Y, otherwise say N.

1995 As a side note, saying Y here will automatically boost HZ to 1000
1996 so that the timer has a chance to clear the overflow counter. On
1997 slower systems (such as the SH-2 and SH-3) this will likely yield
1998 some performance issues. As such, the WDT should be avoided here
