Hi Alexander, I still strongly think we should use toggle events to achieve that: https://lkml.org/lkml/2013/9/25/227 This will let us count not just IRQs (-e 'cycles,irq_entry/on=cycles/,irq_exit/off=cycles/') but much more. The patchset still needs some polishing but I think that's a better diection.
