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
26 table is full.

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

1398 Select the default watchdog timer period to be used by the PowerPC
1399 Book-E watchdog driver. A watchdog "event" occurs when the bit
1400 position represented by this number transitions from zero to one.
1401
1402 For Freescale Book-E processors, this is a number between 0 and 63.
1403 For other Book-E processors, this is a number between 0 and 3.

1455 SuperH processors. If you have one of these processors and wish
1456 to have watchdog support enabled, say Y, otherwise say N.
1457
1458 As a side note, saying Y here will automatically boost HZ to 1000
1459 so that the timer has a chance to clear the overflow counter. On
1460 slower systems (such as the SH-2 and SH-3) this will likely yield
1461 some performance issues. As such, the WDT should be avoided here
