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.rst> in the kernel source.
|
|
|
|
The watchdog is usually used together with the watchdog daemon
|
|
which is available from
|
|
<https://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.

Say Y here if you want to use the new watchdog timer driver core.

|

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.

The default watchdog behaviour (which you get if you say Y here) is
|
|
to ping watchdog devices that were enabled before the driver has
|
|
been loaded until control is taken over from userspace using the
|
|
/dev/watchdog file. If you say N here, the kernel will not update

the watchdog on its own. Thus if your userspace does not start fast

enough your device will reboot.

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.
