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.
21
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.

32config 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).

40config 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.
48
49config WATCHDOG_HANDLE_BOOT_ENABLED
50	bool "Update boot-enabled watchdog until userspace takes over"
51	default y
52	help
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.
59
60config WATCHDOG_SYSFS
