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.

374 The TCO (Total Cost of Ownership) timer is a watchdog timer
375 that will reboot the machine after its second expiration. The
376 expiration time can be configured with the "heartbeat" parameter.
377
378 On some motherboards the driver may fail to reset the chipset's
379 NO_REBOOT flag which prevents the watchdog from rebooting the
380 machine. If this is the case you will get a kernel message like
381 "failed to reset NO_REBOOT flag, reboot disabled by hardware".

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

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

774 Saying Y here and creating a character special file /dev/temperature
775 with major number 10 and minor number 131 ("man mknod") will give
776 you a thermometer inside your computer: reading from
777 /dev/temperature yields one byte, the temperature in degrees
778 Fahrenheit. This works only if you have a WDT501P watchdog board
779 installed.
780
781 If you want to enable the Fan Tachometer on the WDT501P, then you
782 can do this via the tachometer parameter. Only do this if you have a
783 fan tachometer actually set up.
