bool "Watchdog Timer Support"
|
|
---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
|

bool "WatchDog Timer Driver Core"
|
|
---help---
|
|
Say Y here if you want to use the new watchdog timer driver core.
|
|
This driver provides a framework for all watchdog timer drivers
|
|
and gives them the /dev/watchdog interface (and later also the
|
|
sysfs interface).
|
|
|
|
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.

---help---
|
|
This is the driver for the built-in watchdog timer on the EPX-C3
|
|
Single-board computer made by Winsystems, Inc.
|
|
|
|
*Note*: This hardware watchdog is not probeable and thus there
|
|
is no way to know if writing to its IO address will corrupt
|
|
your system or have any real effect. The only way to be sure
|
|
that this driver does what you want is to make sure you
|
|
are running it on an EPX-C3 from Winsystems with the watchdog
|
|
timer at IO address 0x1ee and 0x1ef. It will write to both those
|
|
IO ports. Basically, the assumption is made that if you compile
|
|
this driver into your kernel and/or load it as a module, that you
|
|
know what you are doing and that you are in fact running on an
|
|
EPX-C3 board!

module will be called sbc_epx_c3.
