How to detect interrupt handle routine of a device driver?

Question

Hi,

I'm using Linux platform to program in embedded device.

Is there any way that a kernel module can detect the interrupt handler routine of an another device driver module?

Like for example, I have a kernel module(.ko), then I want this kernel module detect if a particular device driver execute its interrupt handle routine?

Is this possible?

Many thanks.

Answer 1

The simplest way to do this would be to modify the device driver to allow your module to register a callback, which the device driver calls during its interrupt routine or similar.
