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.

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

1737 interrupt. On first expiration of the watchdog, the
1738 interrupt handler pokes it. The second expiration causes an

1740 global soft reset.

1984 to have watchdog support enabled, say Y, otherwise say N.

1986 As a side note, saying Y here will automatically boost HZ to 1000
1987 so that the timer has a chance to clear the overflow counter. On
1988 slower systems (such as the SH-2 and SH-3) this will likely yield
