I suppose you are trying to connect a device gpio/irq output line to another device input, likely using sysbus_connect_irq(). The API is "connect the N-th output line from the SysBus device to this qemu_irq handler", where qemu_irq is the input line. Apparently your SysBus device doesn't have any output line registered. These are registered using sysbus_init_irq(). The first call register the first output IRQ, and so on. Some objects have their QOM interface documented, for example to use the ARM GIC see: https://gitlab.com/qemu-project/qemu/-/blob/master/include/hw/intc/arm_gic.h#L22 Hope that helps. Regards, Phil.
