Thanks Peter.
I have set it up such that master device has qemu_irq array which it
initializes using qdev_init_gpio_out with number of gpio lines going
out and slave device calls qdev_init_gpio_in with a callback that
should be called when irq is raised. Then I connect them together at
higher leve

I'd like to add a virtual device that is controlled by a couple of
GPIO pins on my controller (cortex-m4) and a serial port. I suppose I
can derive it from SSISlaveClass to make the new device a serial
slave.
But how do I connect GPIOs?
I want the slave device to be notified when guest firmware t
