Currently, we call ioapic_service() immediately when we find the irq is still
active during eoi broadcast. But for real hardware, there's some dealy between
the EOI writing and irq delivery (system bus latency?). So we need to emulate
this behavior. Otherwise, for a guest who haven't register a pro

Currently, we call ioapic_service() immediately when we find the irq is still
active during eoi broadcast. But for real hardware, there's some dealy between
the EOI writing and irq delivery (system bus latency?). So we need to emulate
this behavior. Otherwise, for a guest who haven't register a pro
