Abstract

The invention discloses a PCIe-based hot-plug control method, which includes: a hot-plug management module detects whether a target module can respond to a hot-plug signal; if so, the hot-plug management module is located between the target module and a termination point. Act as a signal intermediary to realize the hot-plug power-on process; if not, the hot-plug management module sends an analog signal to the endpoint, where the analog signal is used to simulate the working signal sent by the target module to realize the hot-plug power-on process The embodiment of the present application also provides a hot-plug management module and a storage medium, which can use the hot-plug management module as a signal intermediary between the target module and the termination point to manage signal interaction in a unified manner when the system is working normally. During normal operation, an analog signal is generated to realize hot swapping, which simplifies the problem analysis workload in the process of debugging the system and improves the overall debuggability of the system.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a PCIe-based hot swap control method, device and storage medium. Background technique [0002] PCI-Express (peripheral component interconnect express, PCIe) is a high-speed serial computer expansion bus standard proposed by Intel Corporation. PCIe system includes root complex (root complex, RC), switch (switch, SW) and termination point (end point, EP) three types of devices, among them, RC is the PCIe root controller, which can be understood as a processor, generally composed of a CPU; EP is an end point, such as a general PCIe interface network card device, serial port card device, memory card During the working process, the EP is connected to the RC and accepts the work instructions of the RC. When multiple EPs need to be connected to one RC at the same time, multiple EPs are connected to the SW respectively, and then the SW is connected to the RC, and the SW passes the abov...
