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

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.

1471 This driver adds watchdog support for the integrated watchdog in the
1472 SuperH processors. If you have one of these processors and wish
1473 to have watchdog support enabled, say Y, otherwise say N.
1474
1475 As a side note, saying Y here will automatically boost HZ to 1000
1476 so that the timer has a chance to clear the overflow counter. On
1477 slower systems (such as the SH-2 and SH-3) this will likely yield
1478 some performance issues. As such, the WDT should be avoided here
