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.
