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.

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.

50	bool "Update boot-enabled watchdog until userspace takes over"

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.

2066	  This is the driver for the Berkshire Products PCI-PC Watchdog card.
2067	  This card simply watches your kernel to make sure it doesn't freeze,
2068	  and if it does, it reboots your computer after a certain amount of
2069	  time. The card can also monitor the internal temperature of the PC.
2070	  More info is available at <http://www.berkprod.com/pci_pc_watchdog.htm>.

2072	  To compile this driver as a module, choose M here: the
2073	  module will be called pcwd_pci.

2081	  If you have a PCI-WDT500/501 watchdog board, say Y here, otherwise N.
2082
2083	  If you have a PCI-WDT501 watchdog board then you can enable the
2084	  temperature sensor by setting the type parameter to 501.
2085
2086	  If you want to enable the Fan Tachometer on the PCI-WDT501, then you
2087	  can do this via the tachometer parameter. Only do this if you have a
2088	  fan tachometer actually set up.
