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

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

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.

438 When "Watchdog Timer Value" enabled one can set 31-255 s operational range.

Wim Van Sebroeck9b901ee2009-06-19 09:32:57 +00001082 If you have a PCI-WDT501 watchdog board then you can enable the
1083 temperature sensor by setting the type parameter to 501.

1085 If you want to enable the Fan Tachometer on the PCI-WDT501, then you
1086 can do this via the tachometer parameter. Only do this if you have a
1087 fan tachometer actually set up.

1103 This is the driver for the Berkshire Products USB-PC Watchdog card.
1104 This card simply watches your kernel to make sure it doesn't freeze,
1105 and if it does, it reboots your computer after a certain amount of
1106 time. The card can also monitor the internal temperature of the PC.
