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_IRQ_COUNT line.
You can then use command 'info irq' in the monitor console. This will show
you a count of interrupts for each IRQ.
Regards,
Roger
For example, I wrote a module of a simple memory without implementing
IRQ...
I think it is an error but it works fine... are IRQ raise in any case???
I look at other code source of implemented hw but for each device there is
a
differeny way to raise an interrupt (i see).
Is there a standard way to do this?
The following is an excerpt of my simple memory, please can you describe
me
fastly how can I manage this?
Thank you
