Zhang Haoyu 184564efae kvm: ioapic: conditionally delay irq delivery duringeoi broadcast ... Currently, we call ioapic_service() immediately when we find the irq is still active during eoi broadcast. But for real hardware, there's some delay between the EOI writing and irq delivery. If we do not emulate this behavior, and re-inject the interrupt immediately after the guest sends an EOI and re-enables interrupts, a guest might spend all its time in the ISR if it has a broken handler for a level-triggered interrupt. Such livelock actually happens with Windows guests when resuming from hibernation. As there's no way to recognize the broken handle from new raised ones, this patch delays an interrupt if 10.000 consecutive EOIs found that the interrupt was still high. The guest can then make a little forward progress, until a proper IRQ handler is set or until some detection routine in the guest (such as Linux's note_interrupt()) recognizes the situation.
