On some motherboards the it8712f watchdog does not work unless the game port was enabled. see Bug 13140. We therefor add a note to Kconfig. Signed-off-by: Wim Van Sebroeck <wim@iguana.be>

---help---
|
|
If you say Y here (and to one of the following options) and create a
|
|
character special file /dev/watchdog with major number 10 and minor
|
|
number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
|
|
subsequently opening the file and then failing to write to it for
|
|
longer than 1 minute will result in rebooting the machine. This
|
|
could be useful for a networked machine that needs to come back
|
|
on-line as fast as possible after a lock-up. There's both a watchdog
|
|
implementation entirely in software (which can sometimes fail to
|
|
reboot the machine) and a driver for hardware watchdog boards, which
|
|
are more robust and can also keep track of the temperature inside
|
|
your computer. For details, read
|
|
<file:Documentation/watchdog/watchdog-api.txt> in the kernel source.
|
|
|
|
The watchdog is usually used together with the watchdog daemon
|
|
which is available from
|
|
<ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
|
|
also monitor NFS connections and can reboot the machine when the process
|
|
table is full.
|
|
|
|
If unsure, say N.
|
|
|
|
if WATCHDOG
|
|
|
|
config WATCHDOG_NOWAYOUT
|
|
bool "Disable watchdog shutdown on close"
|
|
help
|
|
The default watchdog behaviour (which you get if you say N here) is
|
|
to stop the timer if the process managing it closes the file
|
|
/dev/watchdog. It's always remotely possible that this process might
|
|
get killed. If you say Y here, the watchdog cannot be stopped once
|
|
it has been started.

IBM s/390 and zSeries machines running under z/VM 5.1 or later

provide a virtual watchdog timer to their guest that cause a

user define Control Program command to be executed after a

timeout.

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

This is the driver for the Berkshire Products ISA-PC Watchdog card.
|
|
This card simply watches your kernel to make sure it doesn't freeze,
|
|
and if it does, it reboots your computer after a certain amount of
|
|
time. This driver is like the WDT501 driver but for different
|
|
hardware. Please read <file:Documentation/watchdog/pcwd-watchdog.txt>. The PC
|
|
watchdog cards can be ordered from <http://www.berkprod.com/>.

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

If you have a PCI-WDT501 watchdog board then you can enable the

|
temperature sensor by setting the type parameter to 501.
|
|
|
|
If you want to enable the Fan Tachometer on the PCI-WDT501, then you

fan tachometer actually set up.
