7 bool "Watchdog Timer Support"
8 ---help---
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
26 table is full.
28 If unsure, say N.

32 config WATCHDOG_CORE
33 bool "WatchDog Timer Driver Core"
34 ---help---
35 Say Y here if you want to use the new 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
38 sysfs interface).
40 config WATCHDOG_NOWAYOUT
41 bool "Disable watchdog shutdown on close"
42 help
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
47 it has been started.

1261 Hardware driver for OCTEON's on chip watchdog timer.
1262 Enables the watchdog for all cores running Linux. It
1263 installs a NMI handler and pokes the watchdog based on an
1264 interrupt. On first expiration of the watchdog, the
1265 interrupt handler pokes it. The second expiration causes an
1266 NMI that prints a message. The third expiration causes a
1267 global soft reset.
1269 When userspace has /dev/watchdog open, no poking is done
1270 from the first interrupt, it is then only poked when the
1271 device is written.
