Hi, This is an experimental series to reduce calls to the cpu_interrupt() API from generic HW/. I'm trying to use the ICH9 chipset from a non-x86 machine. Without this experiment, we can not because cpu_interrupt() is target specific. Here the interrupt is decoupled using the QDev GPIO API. Even if the SMI# line is left unconnected, the device is still usable by a guest.
