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.

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.

1554	The driver can also be built as a module. If so, the module will be
1555	called mena21_wdt.

1577	  IBM s/390 and zSeries machines running under z/VM 5.1 or later
1578	  provide a virtual watchdog timer to their guest that cause a
1579	  user define Control Program command to be executed after a
1580	  timeout.
1581	  LPAR provides a very similar interface. This driver handles
1582	  both.

1594	  This driver adds watchdog support for the integrated watchdog in the
1595	  SuperH processors. If you have one of these processors and wish
1596	  to have watchdog support enabled, say Y, otherwise say N.
1597
1598	  As a side note, saying Y here will automatically boost HZ to 1000
1599	  so that the timer has a chance to clear the overflow counter. On
1600	  slower systems (such as the SH-2 and SH-3) this will likely yield
1601	  some performance issues. As such, the WDT should be avoided here
1602	  unless it is absolutely necessary.

1605	  module will be called shwdt.
