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

17 reboot the machine) and a driver for hardware watchdog boards, which

Linus Torvalds1da177e2005-04-16 15:20:36 -070021
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

348 Note: The IOP13XX watchdog does an Internal Bus Reset which will
349 affect both cores and the peripherals of the IOP. The ATU-X
350 and/or ATUe configuration registers will remain intact, but if
351 operating as an Root Complex and/or Central Resource, the PCI-X
352 and/or PCIe busses will also be reset. THIS IS A VERY BIG HAMMER.

738 It`s possible to enable watchdog timer either from BIOS (F2) or from booted Linux.
739 When "Watchdog Timer Value" enabled one can set 31-255 s operational range.
740
741 Entering BIOS setup temporary disables watchdog operation regardless to current state,
742 so system will not be restarted while user in BIOS setup.
743
744 Once watchdog was enabled the system will be restarted every
745 "Watchdog Timer Value" period, so to prevent it user can restart or

1493 to have watchdog support enabled, say Y, otherwise say N.

1496 so that the timer has a chance to clear the overflow counter. On
1497 slower systems (such as the SH-2 and SH-3) this will likely yield
1498 some performance issues. As such, the WDT should be avoided here
