929  fasteoi = true
930  否则
931  irq_clear_status_flags(irq, IRQ_LEVEL)
932  fasteoi = false
935  hdl等于如果fasteoi则handle_fasteoi_irq - irq handler for transparent controllers*@desc: the interrupt description structure for this irq* Only a single callback will be issued to the chip: an ->eoi()* call when the interrupt has been serviced否则handle_edge_irq - edge type IRQ handler*@desc: the interrupt description structure for this irq* Interrupt occures on the falling and/or rising edge of a hardware* signal.
