8 If you say Y here (and to one of the following options) and create a
9 character special file /dev/watchdog with major number 10 and minor
10 number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
11 subsequently opening the file and then failing to write to it for
12 longer than 1 minute will result in rebooting the machine. This
13 could be useful for a networked machine that needs to come back

16 reboot the machine) and a driver for hardware watchdog boards, which
17 are more robust and can also keep track of the temperature inside

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

34 The default watchdog behaviour (which you get if you say N here) is
35 to stop the timer if the process managing it closes the file
36 /dev/watchdog. It's always remotely possible that this process might
37 get killed. If you say Y here, the watchdog cannot be stopped once
38 it has been started.

1073 This driver adds watchdog support for the integrated watchdog in the
1074 SuperH processors. If you have one of these processors and wish
1075 to have watchdog support enabled, say Y, otherwise say N.
1076
1077 As a side note, saying Y here will automatically boost HZ to 1000
1078 so that the timer has a chance to clear the overflow counter. On
1079 slower systems (such as the SH-2 and SH-3) this will likely yield
1080 some performance issues. As such, the WDT should be avoided here
1081 unless it is absolutely necessary.
