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
17 are more robust and can also keep track of the temperature inside

Linus Torvalds1da177e2005-04-16 15:20:36 -070020
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
46 it has been started.

1385 If you have a WDT500P or WDT501P watchdog board, say Y here,
1386 otherwise N. It is not possible to probe for this board, which means
1387 that you have to inform the kernel about the IO port and IRQ that
1388 is needed (you can do this via the io and irq parameters)
1389
1390 To compile this driver as a module, choose M here: the
1391 module will be called wdt.

1404 This is the driver for the Berkshire Products PCI-PC Watchdog card.
1405 This card simply watches your kernel to make sure it doesn't freeze,
1406 and if it does, it reboots your computer after a certain amount of
1407 time. The card can also monitor the internal temperature of the PC.

Wim Van Sebroeck9b901ee2009-06-19 09:32:57 +00001421 If you have a PCI-WDT501 watchdog board then you can enable the
1422 temperature sensor by setting the type parameter to 501.

1424 If you want to enable the Fan Tachometer on the PCI-WDT501, then you
1425 can do this via the tachometer parameter. Only do this if you have a
1426 fan tachometer actually set up.
