---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
|
|
online 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.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.
|
|
|

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.

Saying Y here and creating a character special file /dev/temperature
|
|
with major number 10 and minor number 131 ("man mknod") will give
|
|
you a thermometer inside your computer: reading from
|
|
/dev/temperature yields one byte, the temperature in degrees
|
|
Fahrenheit. This works only if you have a PCI-WDT501 watchdog board
|
|
installed.
|
|
|
|
If you want to enable the Fan Tachometer on the PCI-WDT501, then you
|
|
can do this via the tachometer parameter. Only do this if you have a
|
|
fan tachometer actually set up.

This is the driver for the Berkshire Products USB-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. The card can also monitor the internal temperature of the PC.
