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.

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

375 The TCO (Total Cost of Ownership) timer is a watchdog timer
376 that will reboot the machine after its second expiration. The
377 expiration time can be configured with the "heartbeat" parameter.
378
379 On some motherboards the driver may fail to reset the chipset's
380 NO_REBOOT flag which prevents the watchdog from rebooting the

720 Say Y here to support the hardware watchdog capability on Sun RIO
721 machines. The watchdog timeout period is normally one minute but
722 can be changed with a boot-time parameter.

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

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

781 Saying Y here and creating a character special file /dev/temperature
782 with major number 10 and minor number 131 ("man mknod") will give
783 you a thermometer inside your computer: reading from
784 /dev/temperature yields one byte, the temperature in degrees
785 Fahrenheit. This works only if you have a WDT501P watchdog board
786 installed.
787
788 If you want to enable the Fan Tachometer on the WDT501P, then you
789 can do this via the tachometer parameter. Only do this if you have a
790 fan tachometer actually set up.
