How to use watchdog in user application

["RIEM-VIS Ruud" <Ruud.RIEM-VIS@xxxxxxxx>]

Hello,

I'm looking for a way to have an application in user space (e.g. daemon) to force a hardware reset if other user applications do not fire the watchdog.
This would allow us to restart even on hangups which we have sometimes in the field.

I've enabled the watchdog in the kernel:

    CONFIG_ETRAX_WATCHDOG=y
    CONFIG_ETRAX_WATCHDOG_NICE_DOGGY=y

but under "watchdog cards"

#   CONFIG_WATCHDOG is not set

Could anyone give me a hint how to achieve this?

Thanks,
