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.
Maxime Good point, I totally forgot about that file in the proc directory. ☺ That was my fault. Nick
