I tried with both pic_set_irq and pic_set_irq_new but nothing happen
(the irq number is 13 and I verified with info irq in qemu monitor).
I tried also to hack i8259.c and the function is not called (I think).
What the first parameter of pic_set_irq_new is referred to?
Another question: why a new v
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 pi
Thank you very much for the answer,so the only think to do to raise correctly an interrupt (I think) is only to raise it when a read funciton is completed (in case of my simple memory) because it will alarm the process in waiting status to read the value in the register.

No. You should
Alessandro,
All you should need to do to raise an IRQ in your code is:
pic_set_irq(s->irq,1);
When the irq is serviced (in one of your ioport traps, I would assume),
knock the irq down:
pic_set_irq(s->irq,0);
For debugging, you might want to go into i8259.c and uncomment the #define
DEBUG_IR
