Until the latest TORO's source, I was using 8259 controller to catch interrupts, but the problem was all the interrupts were captured by the Boot Strap Processor (or core #0). This is not agree with the dedicate hardware model.
In this way, I have started to use the IOAPIC instance of 8259 when TORO runs in a multicore environment. Thus, I can redirect the IRQ to the core where the hardware was dedicated. The dedication must be performed by the user.
This is a new step toward a real multicore kernel.
