Then I don't get its IRQ logic. Does it mean an IRQ to be edge-triggered?
Its model should use qemu_irq_pulse then instead of qemu_irq_raise and
its IRQ line should be connected to edge-sensing input of interrupt controller.
Input that you have used is also used to sense PCI IRQ and is level-sensing.
