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

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

1387 This is a driver for the Mixcom hardware watchdog cards. This
1388 watchdog simply watches your kernel to make sure it doesn't freeze,
1389 and if it does, it reboots your computer after a certain amount of
1390 time.
1391
1392 To compile this driver as a module, choose M here: the
1393 module will be called mixcomwd.

1401 If you have a WDT500P or WDT501P watchdog board, say Y here,
1402 otherwise N. It is not possible to probe for this board, which means
1403 that you have to inform the kernel about the IO port and IRQ that
1404 is needed (you can do this via the io and irq parameters)

1421 This card simply watches your kernel to make sure it doesn't freeze,
1422 and if it does, it reboots your computer after a certain amount of

Wim Van Sebroeck9b901ee2009-06-19 09:32:57 +00001437 If you have a PCI-WDT501 watchdog board then you can enable the
1438 temperature sensor by setting the type parameter to 501.

1440 If you want to enable the Fan Tachometer on the PCI-WDT501, then you
1441 can do this via the tachometer parameter. Only do this if you have a
1442 fan tachometer actually set up.
