Re: [Qemu-devel] Interrupt request info

[Alessandro Corradi]

Thank you very much,
But I don't understand what the first parameter is on pic_set_irq_new...
I tried anyway to implement my hw with pic_set_irq, but in qemu console I didn't see my irq (13) with info irq.
I tried to raise it: pic_set_irq(s->irq,1);

What I need to do to raise irq correctly with pic_set_irq_new specially the first parameter)?

Thank you

No. You should use pic_set_irq_new. Otherwise your code will break on machines
with multiple interrupt controllers.
