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_NOWAYOUT
32	bool "Disable watchdog shutdown on close"
33	help
34	  The default watchdog behaviour (which you get if you say N here) is
35	  to stop the timer if the process managing it closes the file
36	  /dev/watchdog. It's always remotely possible that this process might
37	  get killed. If you say Y here, the watchdog cannot be stopped once
38	  it has been started.

1057	  This is the driver for the Berkshire Products ISA-PC Watchdog card.
1058	  This card simply watches your kernel to make sure it doesn't freeze,
1059	  and if it does, it reboots your computer after a certain amount of
1060	  time. This driver is like the WDT501 driver but for different
1061	  hardware. Please read <file:Documentation/watchdog/pcwd-watchdog.txt>. The PC
1062	  watchdog cards can be ordered from <http://www.berkprod.com/>.
1063
1064	  To compile this driver as a module, choose M here: the
1065	  module will be called pcwd.

1073	  This is a driver for the Mixcom hardware watchdog cards.  This

1086	---help---
1087	  If you have a WDT500P or WDT501P watchdog board, say Y here,
1088	  otherwise N. It is not possible to probe for this board, which means
1089	  that you have to inform the kernel about the IO port and IRQ that
1090	  is needed (you can do this via the io and irq parameters)

1121	  If you have a PCI-WDT500/501 watchdog board, say Y here, otherwise N.
1122
1123	  If you have a PCI-WDT501 watchdog board then you can enable the
1124	  temperature sensor by setting the type parameter to 501.
1125
1126	  If you want to enable the Fan Tachometer on the PCI-WDT501, then you
1127	  can do this via the tachometer parameter. Only do this if you have a
1128	  fan tachometer actually set up.
