Method and apparatus for identifying pci devices, electronic device and readable storage medium

Abstract

The present application relates to the technical field of computers, and provides a method and apparatus for identifying PCI devices, an electronic device and a nonvolatile readable storage medium. The method comprises: acquiring a configuration file of a processor; on the basis of the configuration file, determining an identification sequence of interfaces, and generating an identification sequence list; in response to an identification sequence position modification request, modifying in a basic input output system the identification sequence position of a target interface in the identification sequence list, and adjusting the sequence position of a port resource identifier corresponding to the interface of which the identification sequence position has changed, so as to generate a new identification sequence list; and, according to the new identification sequence list, scanning PCI devices connected to the processor.
