Thanks for your review, Paolo. In my understanding, irq comes from the producer side, while gsi belongs to the consumer, so we need to get the irq from the producer somewhere. I am not sure adding irq here is the good way, but what I need is in the 'update' function, I have irq, gsi in hand. :) Thanks, Feng > > Paolo -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
