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.
27
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).
39
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.

1566	  If you have a PCI-WDT501 watchdog board then you can enable the
1567	  temperature sensor by setting the type parameter to 501.
1568
1569	  If you want to enable the Fan Tachometer on the PCI-WDT501, then you
1570	  can do this via the tachometer parameter. Only do this if you have a

1587	  This is the driver for the Berkshire Products USB-PC Watchdog card.
1588	  This card simply watches your kernel to make sure it doesn't freeze,
1589	  and if it does, it reboots your computer after a certain amount of
1590	  time. The card can also monitor the internal temperature of the PC.
