Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a National Stage Application of PCT/CN2022/122738, filed Sep. 29, 2022, which claims priority to Chinese Patent Application No. 202210131438.8, filed Feb. 14, 2022 in China, and which applications are incorporated herein by reference. To the extent appropriate, a claim of priority is made to each of the above-disclosed applications. TECHNICAL FIELD This present disclosure relates to the technical field of servers, and in particular to a startup control method, apparatus and device for Peripheral Component Interconnect (PCI) devices in an ARM server and a non-transitory computer-readable storage medium. BACKGROUND With continuous innovations and technical breakthroughs in the chip manufacturing process, a 5 nm manufacturing process has been used for advanced RISC machine (hereinafter referred to as ARM) servers, and the slogan that an ARM server itself focuses on low power consumption and high performance is increasingly accepted by more and more customers. Besides, the present disclosure of ARM servers is becoming more and more mature and breaking the monopoly of traditional servers to enter data centers of Internet customers. Thanks to the improvement of the manufacturing process, the number of cores of an ARM server has increased to 80. With the advantage of the number of cores of a single processor, ARMs have overtaken products from other chip manufacturers, and their performance has been qualitatively improved compared with products from other manufacturers. There are vast customer needs especially in the fields of public cloud, cloud games, cloud mobile phones, videos, artificial intelligence (hereinafter referred to as AI), etc. Based on the advantage that a single processor of an ARM has 80 cores, Internet customers have made great profits in deployment of the above services, and the cost performance of such servers has been greatly improved compared with servers based on other architectures, which increases benefits for more and more Internet customers. However, as server products based on emerging architectures, ARM servers have a limited number of deployed present disclosures, and will encounter a variety of problems in the process of deploying present disclosures by various Internet customers. For example, for a NVIDIA TESLA T4 graphics card from NVIDIA (hereinafter referred to as T4 graphics card), failure to be supported by a virtualization container occurs in adaptation to a video service; but under servers based on other architectures, this problem never occurs. As could be seen from the above problem occurring during the adaptation of the ARM server to the T4 graphics card, what must be solved in the process of applying ARM servers to satisfy the requirements of Internet services is an anomaly occurring in adaptation to a peripheral component interconnect (hereinafter referred to as PCI) device under a server based on an ARM architecture.

Optionally, configuring the segment number corresponding to each of the PCI link bridge bus serial numbers in the advanced configuration and power management interface protocol according to the segment number corresponding to each of the PCI devices and the PCI link bridge bus serial number corresponding to each of the PCI devices includes: keeping the segment numbers in the advanced configuration and power management interface protocol unchanged when both the segment numbers and the PCI link bridge bus serial numbers corresponding to same PCI devices match a pre-established initial correspondence between each of the segment numbers and each of the PCI link bridge bus serial numbers in the advanced configuration and power management interface protocol; andupdating the segment numbers corresponding to the PCI link bridge bus serial numbers in the advanced configuration and power management interface protocol in accordance with the segment numbers corresponding to the same PCI devices and the PCI link bridge bus serial numbers corresponding to the same PCI devices so as to satisf
