Link communication method, device and equipment, and computer readable storage medium

Abstract

The invention discloses a link connection method, device and equipment, and a computer readable storage medium. Researches find that under the condition that PCIe equipment is normally connected withcomputer equipment, training of all links can be quickly and accurately completed in a mode of enabling after an uplink port of the PCIe equipment is controlled to be disabled, so that all the links are in normal communication, so the link width of the uplink port is firstly reduced, and the number of links needing to be trained is reduced; and after the down-regulated links are quickly trained and the PCIe equipment is normally communicated with the computer equipment, all the links of the uplink port of the PCIe equipment are quickly completed in a mode of enabling after the uplink port of the PCIe equipment is controlled to be disabled, so the PCIe device is quickly put into use, and the user experience and the working efficiency are improved.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a link communication method, and also relates to a link communication device, equipment, and computer-readable storage medium. Background technique [0002] There are various types of PCIe devices, which can be flexibly connected to the CPU to expand the functions of computer devices. When a PCIe device is working, it may need to reset some of its own registers due to abnormalities and other reasons. At this time, the CPU can control the PCIe device to Hot Reset is used to reset to achieve this purpose. After the PCIe device is reset, the link training between the CPU and the PCIe device needs to be re-trained to achieve normal data interaction, but the link training in this case It often takes a long time, resulting in that the PCIe device cannot be put into use in time, which affects the user experience and reduces the work efficiency. [0003] Therefore, how to provide a solu...

At this time, the CPU can control the PCIe device to Hot Reset is used to reset to achieve this purpose. After the PCIe device is reset, the link training between the CPU and the PCIe device needs to be re-executed to achieve normal data interaction, but the link training in this case It often takes a long time, resulting in the failure of PCIe devices to be put into use in time, affecting user experience and reducing work efficiency
