Problems solved by technology

Generally speaking, when replacing the PCI-E adapter card, the system must be shut down, and then the original PCI-E adapter card must be pulled out. For users who need to frequently replace the PCI-E adapter card for testing quite inconvenient
[0003] On the other hand, the PCI-E adapter card on the main board of the server may also be loosened from the PCI-E slot due to the operator's mistaken touch, which may suddenly interrupt the communication connection and cause the system to crash.

Abstract

A PCI-E interface control system, including a PCI-E slot, a central processing unit, a memory unit and a control unit, the PCI-E slot is connected to a PCI-E adapter card, and the central processing unit passes through the PCI-E slot Communicate with the PCI-E interface card and access the data packets of the PCI-E adapter card; the memory unit temporarily stores the data packets received from the PCI-E adapter card; the PCI-E adapter card receives from the PCI-E slot When detached, the control unit sends a detachment warning message to the central processing unit; when the central processing unit receives the detachment warning message and has not completed receiving and accessing the data packets of the PCI-E adapter card, it records the data packets being accessed access identifier, and disable the communication connection with the PCI‑E adapter card.

Description

technical field [0001] The invention relates to a PCI-E interface control system, in particular to a control system for managing PCI-E hot insertion. Background technique [0002] PCI Express (hereinafter referred to as PCI-E) is a computer bus external connection standard (PCI; Peripheral Component Interconnect), which follows the old PCI programming concepts and communication standards, but greatly improves the transmission rate . At present, PCI-E adapter cards (such as network cards, I / O expansion cards, display adapters, etc.) have been widely used in personal computers and server motherboards to provide more functional expansion. Generally speaking, when replacing the PCI-E adapter card, the system must be shut down, and then the original PCI-E adapter card must be pulled out. For users who need to frequently replace the PCI-E adapter card for testing It's quite inconvenient. [0003] On the other hand, the PCI-E adapter card on the mainboard of the server may also ...
