Abstract

The invention provides a method and system for SBR testing instead of XDP, including: inputting the BDF value of PCIe PORT to be tested, setting the number of cycles and delay value; time operation; execute the Linkdown subroutine, the SBR bit is enabled and set to 0, and the delay operation is performed; the above operations are performed cyclically until the set number of cycles is completed. The present invention realizes the SBR test by running the script, without changing any hardware resources, and can perform the SBR operation by running the script under the system, which can achieve the same effect as the XDP, and can not only save the cost of purchasing the XDP tool, It can also be more convenient to maintain, and you can also change the verification method according to your own needs, improve the speed of problem solving, and maintain the product image.

Description

technical field [0001] The invention relates to the technical field of SBR testing, in particular to a method and a system for performing SBR testing in place of XDP. Background technique [0002] In the current server, there are more and more devices on the PCIe bus on the motherboard, and the speed is getting faster and faster. When there is a problem on the PCIe bus, debugging the PCIe bus is a frequently used method, which can quickly reproduce and solve the problem. Therefore, the XDP interface will be reserved for debugging when the motherboard is designed. [0003] However, in the actual use process, XDP needs to be matched with the host computer software and tools, and the practicability of the tools is not very good, and it is often prone to the phenomenon that the connection cannot be connected, which leads to the situation that debugging cannot be performed. The currently adopted technical solution for PCIe bus SBR test is: use the XDP interface on the motherboar...
