PCIE path configuration method and device, terminal and medium

Abstract

The embodiment of the invention provides a PCIE path configuration method and device, a terminal and a medium which relate to a computer technology, and are used for solving the problem that in the related art, one type of graphics card firmware is only fixedly configured with a lane of one type of corresponding PCIE slot, so that some types of PCIE graphics cards cannot be used in lower slots andcorresponding systems. The method comprises the following steps: configuring a PCIE path of a current PCIE slot into a first type of path through video card firmware; when that the PCIE display cardinstalled in the current PCIE slot is not successfully connected is determined, controlling a PCIE controller to reset through the display card firmware, and configuring the PCIE path as a second typeof path, wherein the number of the channels of the second kind of channels is smaller than that of the channels of the first kind of channels.

Description

technical field [0001] The present application relates to computer technology, in particular to a PCIE channel configuration method, device, terminal and medium. Background technique [0002] PCIE (peripheral component interconnect express, high-speed serial computer expansion bus) graphics cards are suitable for PCIE slots on embedded and desktop system platforms. Since there are different types of PCIE slots, there are also different types of PCIE graphics cards. PCIE slots are divided into x1, x2, x4, x8 and other types according to the number of lanes; corresponding PCIE graphics cards are also divided into x1, x2, x4, x8, and the types of graphics card firmware of PCIE graphics cards are also divided into x1, x2, x4, x8 version. [0003] In related technologies, PCIE graphics cards and PCIE slots are upwardly compatible; for example, x1 PCIE graphics cards can be used on all PCIE slots, and x2 PCIE graphics cards can be used on PCIE slots corresponding to x1. And so ...
