6 bool "Watchdog Timer Support"
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
14 on-line as fast as possible after a lock-up. There's both a watchdog
15 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
19 <file:Documentation/watchdog/watchdog-api.txt> in the kernel source.
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
31 config WATCHDOG_NOWAYOUT
32 bool "Disable watchdog shutdown on close"
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

51 A software monitoring watchdog. This will fail to reboot your system
52 from some situations that the hardware watchdog will recover

777 tristate "RIO Hardware Watchdog support"
778 depends on SPARC64 && PCI
780 Say Y here to support the hardware watchdog capability on Sun RIO
781 machines. The watchdog timeout period is normally one minute but
782 can be changed with a boot-time parameter.

799 This is the driver for the Berkshire Products ISA-PC Watchdog card.
800 This card simply watches your kernel to make sure it doesn't freeze,
801 and if it does, it reboots your computer after a certain amount of
802 time. This driver is like the WDT501 driver but for different
803 hardware. Please read <file:Documentation/watchdog/pcwd-watchdog.txt>. The PC
804 watchdog cards can be ordered from <http://www.berkprod.com/>.
806 To compile this driver as a module, choose M here: the
807 module will be called pcwd.
809 Most people will say N.

826 tristate "WDT Watchdog timer"
829 If you have a WDT500P or WDT501P watchdog board, say Y here,
830 otherwise N. It is not possible to probe for this board, which means
831 that you have to inform the kernel about the IO port and IRQ that
832 is needed (you can do this via the io and irq parameters)
834 To compile this driver as a module, choose M here: the
835 module will be called wdt.
838 bool "WDT501 features"
841 Saying Y here and creating a character special file /dev/temperature
842 with major number 10 and minor number 131 ("man mknod") will give
843 you a thermometer inside your computer: reading from
844 /dev/temperature yields one byte, the temperature in degrees
845 Fahrenheit. This works only if you have a WDT501P watchdog board
848 If you want to enable the Fan Tachometer on the WDT501P, then you
849 can do this via the tachometer parameter. Only do this if you have a
850 fan tachometer actually set up.
