Abstract

Embodiments of the present invention provide a method and device for interconnection and enumeration of external devices in a multi-node system. The multi-node system includes a master node and at least one slave node, and the method includes: the master node obtains the first external device interconnection PCI enumeration result of the master node; the master node obtains each slave node in the multi-node system The corresponding second PCI enumeration result: the master node generates the PCI tree of the multi-node system according to the first PCI enumeration result and the second PCI enumeration result corresponding to the slave nodes. The method provided by the embodiment of the present invention improves the start-up speed of the multi-node system, and further shortens the start-up time of the multi-node system.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a method and device for interconnecting and enumerating external devices in a multi-node system. Background technique [0002] Peripheral Component Interconnect (hereinafter referred to as PCI) is an interconnection bus whose transmission rate is greatly improved compared with traditional buses. A device that uses the PCI bus as a standard is called a PCI device. For the Basic Input / Output System (BIOS) of the Unified Extensible Firmware Interface (hereinafter referred to as UEFI), it is necessary to pass the PCI Enumeration enables these PCI devices. Among them, PCI enumeration is to dynamically query the PCI bridges and PCI devices of the system, and assign bus (BUS) numbers to the queried bridges, and allocate resources to bridges and devices; finally load Option Rom and drivers to complete the initialization of PCI devices , and then...
