dummy interrupt handler using timer

[Pintu Kumar]

Hi,

I wanted to develop a dummy interrupt handler for an ARM board which
is connected to a remote location. This is required for some debugging
purpose during the interrupt context.
It does not have a keyboard or any GPIO pins.

So, I wonder how to develop a custom interrupt handler, may be using
timer invocation.

If anybody can give some pointers or reference, it will be of great help.

Thanks,
Pintu
