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

735 that will reboot the machine after its second expiration. The
736 expiration time can be configured with the "heartbeat" parameter.

1352 so that the timer has a chance to clear the overflow counter. On
1353 slower systems (such as the SH-2 and SH-3) this will likely yield

1394 Say Y here to support the hypervisor watchdog capability provided
1395 by Xen 4.0 and newer. The watchdog timeout period is normally one
1396 minute but can be changed with a boot-time parameter.

1413 This is the driver for the Berkshire Products ISA-PC Watchdog card.
1414 This card simply watches your kernel to make sure it doesn't freeze,
1415 and if it does, it reboots your computer after a certain amount of
1416 time. This driver is like the WDT501 driver but for different
1417 hardware. Please read <file:Documentation/watchdog/pcwd-watchdog.txt>. The PC
1418 watchdog cards can be ordered from <http://www.berkprod.com/>.

1421 module will be called pcwd.

1443 If you have a WDT500P or WDT501P watchdog board, say Y here,
1444 otherwise N. It is not possible to probe for this board, which means
1445 that you have to inform the kernel about the IO port and IRQ that
1446 is needed (you can do this via the io and irq parameters)

1448 To compile this driver as a module, choose M here: the
1449 module will be called wdt.

Wim Van Sebroeck9b901ee2009-06-19 09:32:57 +00001479 If you have a PCI-WDT501 watchdog board then you can enable the
