Hi,
I would like to somehow obtain local CPU core ID in the interrupt handler function. I want to see how my interruptions are distributed among different CPU cores under different conditions.
How should I do that?
To answer strictly your question, like Nick said, smp_processor_id() will work fine. However, you can do exactly what you want be reading /proc/interrupts, that already provide the informations you are looking for.
