6	bool "Watchdog Timer Support"
7	---help---
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.
20
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
25	  table is full.
26
27	  If unsure, say N.

31config WATCHDOG_CORE
32	bool "WatchDog Timer Driver Core"
33	---help---
34	  Say Y here if you want to use the new watchdog timer driver core.
35	  This driver provides a framework for all watchdog timer drivers
36	  and gives them the /dev/watchdog interface (and later also the
37	  sysfs interface).
38
39config WATCHDOG_NOWAYOUT
40	bool "Disable watchdog shutdown on close"
41	help
42	  The default watchdog behaviour (which you get if you say N here) is
43	  to stop the timer if the process managing it closes the file
44	  /dev/watchdog. It's always remotely possible that this process might
45	  get killed. If you say Y here, the watchdog cannot be stopped once
46	  it has been started.

1040	  Enables the watchdog for all cores running Linux. It
1041	  installs a NMI handler and pokes the watchdog based on an
1042	  interrupt.  On first expiration of the watchdog, the
1043	  interrupt handler pokes it.  The second expiration causes an
1044	  NMI that prints a message. The third expiration causes a
1045	  global soft reset.
