7 bool "Watchdog Timer Support"
9 If you say Y here (and to one of the following options) and create a
10 character special file /dev/watchdog with major number 10 and minor
11 number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
12 subsequently opening the file and then failing to write to it for
13 longer than 1 minute will result in rebooting the machine. This
14 could be useful for a networked machine that needs to come back
15 on-line as fast as possible after a lock-up. There's both a watchdog
16 implementation entirely in software (which can sometimes fail to
17 reboot the machine) and a driver for hardware watchdog boards, which
18 are more robust and can also keep track of the temperature inside
19 your computer. For details, read
20 <file:Documentation/watchdog/watchdog-api.txt> in the kernel source.
22 The watchdog is usually used together with the watchdog daemon
23 which is available from
24 <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
25 also monitor NFS connections and can reboot the machine when the process
33 bool "WatchDog Timer Driver Core"

36 This driver provides a framework for all watchdog timer drivers
37 and gives them the /dev/watchdog interface (and later also the
40 config WATCHDOG_NOWAYOUT
41 bool "Disable watchdog shutdown on close"
43 The default watchdog behaviour (which you get if you say N here) is
44 to stop the timer if the process managing it closes the file
45 /dev/watchdog. It's always remotely possible that this process might
46 get killed. If you say Y here, the watchdog cannot be stopped once
49 config WATCHDOG_HANDLE_BOOT_ENABLED
50 bool "Update boot-enabled watchdog until userspace takes over"
53 The default watchdog behaviour (which you get if you say Y here) is
54 to ping watchdog devices that were enabled before the driver has
55 been loaded until control is taken over from userspace using the
56 /dev/watchdog file. If you say N here, the kernel will not update
57 the watchdog on its own. Thus if your userspace does not start fast
58 enough your device will reboot.

305 here if you wish to use this. Alternatively say M to compile the
306 driver as a module, which will be called wdt285.

447 and/or ATUe configuration registers will remain intact, but if
448 operating as an Root Complex and/or Central Resource, the PCI-X
