can't you have different IRQs for each pad ? I mean, allocate one irq_desc for each pad and let drivers request a pad/pin as an IRQ source. Then, when you detect a pad wakeup, you can: unsigned pad_irq = pad_number - pad->irq_base; handle_nested_thread(pad_irq); this will make use of threaded IRQ handlers even. Could it be something like that ? -- balbi
