Description

Technical Field

[0001] The present invention relates to the field of computer technology, and more particularly to a test method, system, device and storage medium for the BIOS EDPC function. Background Art

[0002] EDPC, full name Enhanced Downstream Port Containment, will trigger the EDPC mechanism function only when errors such as error occur, directly disable the link, and restore the link after the trigger state is cleared.

[0003] With the rapid development of computer technology, servers have gradually become high-performance computers in the network platform. With the wide application and continuous development of scientific and technological progress, there is an increasing demand for the performance upgrade of servers. PCIE devices are used for data input and output of servers, and the quality of PCIE devices will directly affect the integrity of data transmission for customers.

[0004] Currently, when an external device fails, the main processing methods include:

[0005] 1. By replacing the failed device with a new device of the same model, the server can be restarted, and then functions such as PXE function, data transmission, and protocols can be obtained again.

[0006] 2. By disabling the use of this external device in the BIOS menu, this device cannot be viewed under the OS and web, and then functions such as PXE function, data transmission, and protocols cannot be used one after another.

[0007] Since most customers will insert multiple external devices to save costs when using servers, and when an external device fails, the system will report a large number of device failure information logs, which will seriously affect the operation of the server. If the existing processing methods are used for fault handling, it is necessary to power off and replace the faulty device, which seriously affects the customer experience. At the same time, the faulty device can only be replaced with a new device of the same model, resulting in the idleness of the faulty device and increased costs. At this time, if the BIOS has the EDPC function, it can well recover the faulty device without shutting down the computer to ensure that the functions of this device (such as PXE function, data transmission, and protocols) are still normal.

[0008] Therefore, it is an urgent problem for us to effectively test and verify the EDPC function of the BIOS. Summary of the Invention

Specific Embodiments

[0056] In order to enable those skilled in the art of this technology to better understand the solution of the present invention, the following will further describe the present invention in detail with reference to the drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0057] Embodiment 1:

[0058] Such as Figure 1As shown in the figure, this embodiment provides a test method for the BIOS EDPC function, including the following steps:

[0059] S1: Under the AMD platform, remove all externally plugged PCIE devices, obtain PCIE device information, and record it as X.

[0060] Specifically, remove all externally plugged PCIE devices, execute the AMD platform command under the current operating system to output PCIE device-related information, and record it as X.

[0061] Among them, the PCIE device-related information includes socket information, PCIE core information, PCIE port information, and NBIO information.

[0062] S2: Insert an externally plugged PCIE device, obtain PCIE device information, and record it as Y.

[0063] Specifically, insert an externally plugged PCIE device, execute the AMD platform command under the current operating system to output PCIE device-related information, and record it as Y.

[0064] S3: Compare X with Y, and take the different part as the NBIO information of the externally plugged PCIE device, and record it as parameter Z.

[0065] S4: Confirm that the current operating system supports the BERT function.

[0066] Among them, the BERT function is a table plugin under the OS. For low-version OS, this plugin is not available and needs to be installed separately; for high-version OS, this plugin will be automatically installed during the installation process. Therefore, in this method, it is necessary to first confirm whether this plugin exists, otherwise the next function verification cannot be carried out.

[0067] Specifically: Judge whether the current operating system supports the BERT function by reading the BIOS serial port information. If it supports, continue to execute the next step. If it does not support, install the BERT component under the current operating system, and continue to judge whether the current operating system supports the BERT function.

[0068] S5: Confirm that the externally plugged PCIE device supports the ACS function.

[0069] Specifically, judge whether the ACS function of the BIOS is enabled by reading the BIOS serial port information. If it is enabled, continue to execute the next step. If it is not enabled, replace the externally plugged PCIE device, and continue to judge whether the ACS function of the BIOS is enabled.

[0070] It should be noted specifically that: The ACS function, whose full name is Access Control Service, is supported by some devices in the external plug-in devices.

[0071] S6: Modify the EDPC-related function options under BIOS SETUP, save and restart, and enter the operating system interface.

[0072] S7: Use the AMD platform debugging tool, in combination with the preset script, input the parameter Z into the first simulated error injection command to simulate the failure of the external plug-in PCIE device.

[0073] Use the AMD platform debugging tool AMD System Debugger NDA, in combination with the CScripts script, input the parameter Z into the first simulated error injection command. At this time, the serial port will continuously print information. If the error injection is successful, the "pass" information will be displayed. At the same time, the system information module will report the "PCIE uncorrectable error log", and the data transmission link under the operating system will be interrupted and unable to output continuously normally; if the error injection fails, the "fail" information will be displayed. At this time, it is necessary to continuously inject errors until the "pass" information is displayed.

[0074] S8: When the external plug-in PCIE device has failed successfully, input the parameter Z into the second simulated error injection command to repair the failure of the external plug-in PCIE device.

[0075] S9: Check the output information to confirm whether the BIOS supports the EDPC function.

[0076] When the external plug-in PCIE device has failed successfully, after inputting the parameter Z into the second simulated error injection command 2, the serial port will continuously print output information. If the device repair is successful, the "EDPC repair" information will be displayed. At the same time, the system information module will report the "PCIE RECOVERY recovery log", and the data transmission link under the operating system will be reconnected and the data will be output continuously normally. At this time, it indicates that the BIOS supports the EDPC function, that is, the EDPC function verification is completed; if the device repair fails, the "no EDPCrepair" information will be displayed, indicating that the BIOS does not support the EDPC function, that is, the EDPC function verification is completed.

[0077] This embodiment provides a test method for the BIOS EDPC function. By capturing the NBIO-related information parameters, commands are input to the externally plugged PCIE device to simulate a fault. When the device has successfully failed, commands are input to this device again through the captured NBIO-related information parameters to recover the fault. In this way, it is verified whether the BIOS has the EDPC function. If the BIOS has this function, it will enable the recovery of the PCIE device when the server is running normally, so as to ensure the normal operation of functions such as the PXE function, data transmission, and protocols of this device. This method can greatly save the cost of device replacement, highlight the highlights of server performance, and improve the user experience.

[0092] The second error injection unit 8 is used to input the parameter Z into the second simulated error injection command to repair the failure of the externally inserted PCIE device when the externally inserted PCIE device has successfully failed.

[0093] The determination unit 9 is used to confirm whether the BIOS supports the EDPC function by viewing the output information.

[0094] Specifically, if the "EDPC repair" information is displayed and the PCIE RECOVERY recovery log is reported, it indicates that the BIOS supports the EDPC function; if the "no EDPC repair" information is displayed, it indicates that the BIOS does not support the EDPC function.

[0095] This embodiment provides a test system for the BIOS EDPC function. By capturing the NBIO - related information parameters, commands are input to the externally - plugged PCIE device to simulate a fault. When the device has successfully failed, commands are input to this device again through the captured NBIO - related information parameters to recover the fault.
