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.

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.

395 This driver can be used with the watchdog timer found on some
396 single board computers, namely the 6010 PII based computer.
397 It may well work with other cards. It reads port 0x443 to enable
398 and re-set the watchdog timer, and reads port 0x45 to disable
399 the watchdog. If you have a card that behave in similar ways,
400 you can probably make this driver work with your card as well.
401
402 You can compile this driver directly into the kernel, or use
403 it as a module. The module will be called sbc60xxwdt.

724 can do this via the tachometer parameter. Only do this if you have a
725 fan tachometer actually set up.

738 This is the driver for the Berkshire Products PCI-PC Watchdog card.
739 This card simply watches your kernel to make sure it doesn't freeze,
740 and if it does, it reboots your computer after a certain amount of
741 time. The card can also monitor the internal temperature of the PC.
742 More info is available at <http://www.berkprod.com/pci_pc_watchdog.htm>.

744 To compile this driver as a module, choose M here: the
745 module will be called pcwd_pci.

747 Most people will say N.

753 If you have a PCI-WDT500/501 watchdog board, say Y here, otherwise N.

762 Saying Y here and creating a character special file /dev/temperature
763 with major number 10 and minor number 131 ("man mknod") will give
764 you a thermometer inside your computer: reading from
765 /dev/temperature yields one byte, the temperature in degrees
766 Fahrenheit. This works only if you have a PCI-WDT501 watchdog board
767 installed.
768
769 If you want to enable the Fan Tachometer on the PCI-WDT501, then you
770 can do this via the tachometer parameter. Only do this if you have a
771 fan tachometer actually set up.
