6 bool "Watchdog Timer Support"
7 ---help---
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
14 on-line as fast as possible after a lock-up. There's both a watchdog
15 implementation entirely in software (which can sometimes fail to
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
18 your computer. For details, read
19 <file:Documentation/watchdog/watchdog-api.txt> in the kernel source.
20
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.

33 help
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.

585 This is the driver for the built-in watchdog timer on the EPX-C3
586 Single-board computer made by Winsystems, Inc.
587
588 *Note*: This hardware watchdog is not probeable and thus there
589 is no way to know if writing to its IO address will corrupt
590 your system or have any real effect. The only way to be sure
591 that this driver does what you want is to make sure you
592 are running it on an EPX-C3 from Winsystems with the watchdog
593 timer at IO address 0x1ee and 0x1ef. It will write to both those
594 IO ports. Basically, the assumption is made that if you compile
595 this driver into your kernel and/or load it as a module, that you
596 know what you are doing and that you are in fact running on an
597 EPX-C3 board!

704 As a side note, saying Y here will automatically boost HZ to 1000
705 so that the timer has a chance to clear the overflow counter. On
706 slower systems (such as the SH-2 and SH-3) this will likely yield
