Abstract

The invention provides a method and a system for replacing XDP for SBR testing. The method comprises the steps of inputting a BDF value of PCIe PORT to be tested, and setting the number of cycles anda delay value; executing a Linkup subprogram, setting SBR bit enable 1, and carrying out delay operation; executing a Linkdown subprogram, setting SBR bit enabling 0, and performing delay operation; and circularly executing the operation until the set number of cycles is completed. According to the invention, the SBR test is realized in a script running manner; any hardware resource does not needto be changed; the SBR operation is carried out in a script running mode under the system, the effect same as that of XDP can be achieved, the cost for purchasing an XDP tool can be saved, maintenancecan be carried out more conveniently, the verification mode and the like can be changed according to the needs of a user, the problem solving speed is increased, and a product image is maintained.

Description

technical field [0001] The invention relates to the technical field of SBR testing, in particular to a method and system for performing SBR testing instead of XDP. Background technique [0002] In current servers, 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 often used, which can quickly reproduce and solve it. Therefore, the XDP interface will be reserved in the design of the motherboard for Debug use. [0003] However, in the actual use process, XDP needs to be equipped with host computer software and tools, but the practicability of the tools is not very good, and it is often easy to fail to connect, resulting in failure to debug. The technical scheme of the PCIe bus SBR test currently adopted is: use the XDP interface on the main board, enter the corresponding command on the host computer software, connect to the main board interface thro...
