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

49 tristate "Software watchdog"
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.
55 To compile this driver as a module, choose M here: the
56 module will be called softdog.
58 config WM831X_WATCHDOG
59 tristate "WM831x watchdog"

70 the watchdog triggers the system will be reset.
76 config AT91RM9200_WATCHDOG
77 tristate "AT91RM9200 watchdog"
78 depends on ARCH_AT91RM9200
80 Watchdog timer embedded into AT91RM9200 chips. This will reboot your
81 system when the timeout is reached.

94 The Intel Footbridge chip contains a built-in watchdog circuit. Say Y
95 here if you wish to use this. Alternatively say M to compile the
96 driver as a module, which will be called wdt285.
98 This driver does not work on all machines. In particular, early CATS

100 lock up if the watchdog fires.
102 "If in doubt, leave it out" - say N.
105 tristate "NetWinder WB83C977 watchdog"
106 depends on FOOTBRIDGE && ARCH_NETWINDER
108 Say Y here to include support for the WB977 watchdog included in

135 which doesn't reset any peripherals. There are circumstances

787 This is the driver for the built-in watchdog timer on the EPX-C3
788 Single-board computer made by Winsystems, Inc.
790 *Note*: This hardware watchdog is not probeable and thus there
791 is no way to know if writing to its IO address will corrupt
792 your system or have any real effect. The only way to be sure
793 that this driver does what you want is to make sure you
794 are running it on an EPX-C3 from Winsystems with the watchdog
795 timer at IO address 0x1ee and 0x1ef. It will write to both those
796 IO ports. Basically, the assumption is made that if you compile

976 to have watchdog support enabled, say Y, otherwise say N.
978 As a side note, saying Y here will automatically boost HZ to 1000
979 so that the timer has a chance to clear the overflow counter. On
980 slower systems (such as the SH-2 and SH-3) this will likely yield
981 some performance issues. As such, the WDT should be avoided here
