429  data等于q_domain_get_irq_data - Get irq_data associated with @virq and @domain*@domain: domain to match*@virq: IRQ number to get irq_data
430  dgc等于gc
431  hw_irq等于硬件中断号
435  gc等于q_get_domain_generic_chip - Get a pointer to the generic chip of a hw_irq*@d: irq domain pointer*@hw_irq: Hardware interrupt number
