Problems solved by technology

Simply reading the information speed and bandwidth information of the PCIE device can only show that the PCIE device is in a normal working state in the static state, and the bandwidth and information speed obtained in the static state are the response to the state of the PCIE device after the system starts. changes, the static acquisition method cannot detect the dynamically changing link connection status, which will result in incomplete detection of the link connectivity of the PCIE device

Embodiment Construction

[0021] Please refer to figure 1 , is an operating environment diagram of the link connectivity detection system 100 in an embodiment of the present invention. The system 100 runs on an electronic device 200, which can be a personal computer or a server. The electronic device 200 includes a storage unit 10 , a processing unit 20 , at least one PCIE device 30 and a downstream device 40 connected to and communicating with the PCIE device 30 . The link connectivity detection system 100 is stored in the storage unit 10 and can be called and executed by the processing unit 20 . In other implementations, the system 100 is a program solidified in the processing unit 20 . The relevant driver of this PCIE device 30 searches for the PCIE device 30 according to the method of recursively scanning the PCI (Peripheral Component Interconnect) bus during the operation of the operating system of the electronic device 200, and simultaneously in the process of scanning the PCIE device 30, each ...

Abstract

The invention relates to the field of automated testing, in particular to a PCIE (Peripheral Component Interconnect Express) equipment link connectivity detection system and method. The method comprises the following steps: reading link state information in an attribute file of PCIE equipment to detect link connectivity between the PCIE equipment and downstream equipment, and performing control to realize an action process in which a link state between the PCIE equipment and the downstream equipment becomes disconnected from a stable connection and then recovers; and judging whether link state information values between the PCIE equipment and the downstream equipment before and after an action are equal or not to verify whether a link connection of the PCIE equipment succeeds or fails. Through adoption of the system and the method, dynamically-varying link connectivity of the PCIE equipment can be verified rapidly and accurately, and a testing aim is fulfilled more effectively.

Description

technical field [0001] The invention relates to the field of automated testing, in particular to a PCIE (Peripheral Component Interconnect Express, peripheral component interconnection standard) device link connectivity detection system and method. Background technique [0002] At this stage, it is often used to read the current information speed and current bandwidth information of the PCIE device to verify the working status of the PCIE device. Simply reading the information speed and bandwidth information of the PCIE device can only show that the PCIE device is in a normal working state in the static state, and the bandwidth and information speed obtained in the static state are the response to the state of the PCIE device after the system starts. changes, the static acquisition method cannot detect the dynamically changing link connection state, which will cause incomplete detection of the link connectivity of the PCIE device. Contents of the invention [0003] In vie...
