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

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.

42 The default watchdog behaviour (which you get if you say N here) is
43 to stop the timer if the process managing it closes the file
44 /dev/watchdog. It's always remotely possible that this process might
45 get killed. If you say Y here, the watchdog cannot be stopped once

699 This driver can be used with the watchdog timer found on some
700 single board computers, namely the 6010 PII based computer.
701 It may well work with other cards. It reads port 0x443 to enable
702 and re-set the watchdog timer, and reads port 0x45 to disable
703 the watchdog. If you have a card that behave in similar ways,
704 you can probably make this driver work with your card as well.

706 You can compile this driver directly into the kernel, or use
707 it as a module. The module will be called sbc60xxwdt.

1138 to have watchdog support enabled, say Y, otherwise say N.
1139
1140 As a side note, saying Y here will automatically boost HZ to 1000
1141 so that the timer has a chance to clear the overflow counter. On
1142 slower systems (such as the SH-2 and SH-3) this will likely yield
1143 some performance issues. As such, the WDT should be avoided here
