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
Wim Van Sebroecke0845bf2006-09-02 17:59:54 +020014 on-line as fast as possible after a lock-up. There's both a watchdog
Linus Torvalds1da177e2005-04-16 15:20:36 -070015 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 <file:Documentation/watchdog/watchdog.txt>
19 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.
26
27 If unsure, say N.

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.

724 This is a driver for the Mixcom hardware watchdog cards. This
725 watchdog simply watches your kernel to make sure it doesn't freeze,
726 and if it does, it reboots your computer after a certain amount of
727 time.

729 To compile this driver as a module, choose M here: the
730 module will be called mixcomwd.

738 If you have a WDT500P or WDT501P watchdog board, say Y here,
739 otherwise N. It is not possible to probe for this board, which means
740 that you have to inform the kernel about the IO port and IRQ that
741 is needed (you can do this via the io and irq parameters)

750 Saying Y here and creating a character special file /dev/temperature
751 with major number 10 and minor number 131 ("man mknod") will give
752 you a thermometer inside your computer: reading from
753 /dev/temperature yields one byte, the temperature in degrees
754 Fahrenheit. This works only if you have a WDT501P watchdog board
755 installed.
756
757 If you want to enable the Fan Tachometer on the WDT501P, then you
758 can do this via the tachometer parameter. Only do this if you have a
759 fan tachometer actually set up.
