ASPM test method, system, device and medium

Abstract

The invention discloses an ASPM test method. The method comprises the following steps: acquiring an recognition number of a device to be tested and an recognition number of a root port corresponding to the device to be tested; obtaining a value of a first register corresponding to the to-be-tested equipment according to the recognition number of the to-be-tested equipment, and obtaining a value of a second register corresponding to the root port according to the recognition number of the root port; judging whether the value of the first register is not less than the value of the second register; responding to the condition that the value of the first register is not smaller than the value of the second register, and confirming that the test passes. The invention further discloses a system, computer equipment and a readable storage medium. According to the scheme provided by the invention, the relationship between the L1 exit time of the root port and the L1 exit time of the to-be-tested equipment is positioned by checking the register, so that the test accuracy is ensured, and the test time is greatly saved.

Description

technical field [0001] The invention relates to the testing field, in particular to an ASPM testing method, system, equipment and storage medium. Background technique [0002] Many PCIE devices in the server, such as network cards, graphics cards, and NVME, support the ASPM function. Currently, the Whitley platform supports two modes of ASPM: L0s and L1. Among them, L0s is the link standby mode, and L1 is the low power consumption standby mode. Due to the large number of PCIE devices, when performing ASPM tests on PCIE devices, generally under Linux, run the lspci-sxxx–vvv command (xxx represents the BDF number of the PCIE device), and then view the device to be tested in the output content ASPM-related information under LnkCap and Device LnkCtl to determine whether the setting takes effect. [0003] However, existing testing methods have the following problems: [0004] 1. The Linux OS itself has its own power management, which will have a certain impact on the ASPM fun...

Problems solved by technology

[0004]1. The Linux OS itself has its own power management, which will have a certain impact on the ASPM function of the PCIE device, so the results may be inaccurate;

[0005]2. Every time a PCIE device is replaced, the BDF number of the device must be searched again, and then execute the lspci –s BDF vvv command. Each PCIE device supports different functions. Search There are many lines in the ASPM information, and it is easy to find the wrong line in the position

Especially when it is set to Per-Port, it is necessary to set ASPM separately for a s
