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
53 from. Equally it's a lot cheaper to install.

99 depends on FOOTBRIDGE && ARCH_NETWINDER

735 tristate "Winsystems SBC EPX-C3 watchdog"
738 This is the driver for the built-in watchdog timer on the EPX-C3
739 Single-board computer made by Winsystems, Inc.
741 *Note*: This hardware watchdog is not probeable and thus there
742 is no way to know if writing to its IO address will corrupt
743 your system or have any real effect. The only way to be sure
744 that this driver does what you want is to make sure you
745 are running it on an EPX-C3 from Winsystems with the watchdog
746 timer at IO address 0x1ee and 0x1ef. It will write to both those
747 IO ports. Basically, the assumption is made that if you compile
748 this driver into your kernel and/or load it as a module, that you
749 know what you are doing and that you are in fact running on an

912 tristate "SuperH Watchdog"
913 depends on SUPERH && (CPU_SH3 || CPU_SH4)
915 This driver adds watchdog support for the integrated watchdog in the
916 SuperH processors. If you have one of these processors and wish
917 to have watchdog support enabled, say Y, otherwise say N.
919 As a side note, saying Y here will automatically boost HZ to 1000
920 so that the timer has a chance to clear the overflow counter. On
921 slower systems (such as the SH-2 and SH-3) this will likely yield
922 some performance issues. As such, the WDT should be avoided here
923 unless it is absolutely necessary.

958 Say Y here to support the hardware watchdog capability on Sun RIO
959 machines. The watchdog timeout period is normally one minute but

1007 that you have to inform the kernel about the IO port and IRQ that
1008 is needed (you can do this via the io and irq parameters)
