20140115193 | METHOD AND DEVICE FOR ENUMERATING INPUT/OUTPUT DEVICES - Embodiments of the present disclosure relate to a method and a device for enumerating input/output devices (IO devices). The method for enumerating input/output devices includes: acquiring an identifier of each processor and an identifier of each input/output (IO) centralized controller in a system; separately instructing processors to simultaneously enumerate a specific IO centralized controller and an input/output IO device connected to the specific IO centralized controller, according to the identifier of each processor and the identifier of each IO centralized controller; and acquiring related information of IO devices enumerated by the instructed processors. According to the embodiments of the present disclosure, the work of enumerating the system IO devices may be allocated to multiple processors to be carried out simultaneously, so as to greatly reduce time consumed in the enumeration process, and to accelerate a system initialization process. | 04-24-2014 |
