As we have almost 80 irq lines and 40-45 NVIC_irq's.= =C2=A0

Where can I define them= ?

QOM: "QEMU Object Model"

See https://qemu-project.git= lab.io/qemu/devel/qom.html

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_gi= c.h#L22

Hope that helps.

Regards,

Phil.
