[0056] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to specific examples and the accompanying drawings.

[0057] Based on the above objectives, a first aspect of the embodiments of the present invention provides an embodiment of a method for diagnosing a data processor. Figure 1 The diagram shown is a schematic flowchart of the method.

[0058] like Figure 1 As shown, the method may include the following steps:

[0059] S1 connects the server and data processor to the diagnostic network separately and initiates server performance testing. The server and DPU are then connected to the diagnostic PXE (Preboot Execution Environment) network, booting into the diagnostic OS (system) via the PXE network to begin the diagnostic process. After the DPU enters the diagnostic OS, it remains stationary until the server completes firmware updates and cycle testing, reaching a stable state before starting DPU diagnostic testing. Server cycle testing includes AC cycle (power-on / off cycle), DC cycle (power-on / off cycle), and reboot cycle tests to prevent DPU testing interruption due to server power loss during cycle testing. Server performance testing includes firmware updates, including updates to the BMC, BIOS, CPLD, hard drive, network card, HCA card, and GPU firmware. Server configuration checks include DPU presence checks. Server health checks include DPU bandwidth rate checks and sensor information checks. The server cycle test includes AC cycle, DC cycle, and reboot cycle tests. After each cycle, the server restarts and checks the DPU's presence and health status. The server undergoes stress tests on components such as CPU, memory, and hard drive. If all the above tests are normal, the server waits for the DPU test to begin.

[0060] In response to the completion of server performance testing, S2 updates the firmware of each data processor component. After the server test is completed, the DPU performs the update process first, including updating the DPU's FRU, BMC, BIOS, and FPGA firmware. After the update is complete, the power cycle takes effect.

[0061] In response to the completion of firmware updates for the data processor, S3 performs diagnostic tests on all internal components of the data processor. Once the DPU's components have been updated, diagnostic tests are initiated on all internal components of the DPU, including on-premises status checks, health checks, stress tests, and performance tests for each component (CPU, memory, hard drive, network card, FPGA chip, etc.). Server-side stress testing of the DPU is added, as well as interaction tests between the server and the DPU. During the diagnostic process, the DPU periodically checks the server's power-on / off status. If the server is powered off and is undergoing tests such as AC cycle testing or firmware update, a power-on command is sent out-of-band to power on the server.

[0062] In response to the successful diagnostic tests of all components within the data processor, S4 performs a direct memory access stress test on the server side and outputs a test report. After the diagnostic tests of all components of the DPU pass, a DPU DMA (Direct Memory Access) stress test is performed on the server side. After the stress test is completed, the configuration information and health status of the DPU are checked. If the configuration information and health status of the data processor are normal, a test report is output.

[0063] By using the technical solution of the present invention, the diagnostic test coverage of the server paired with the data processor can be improved, further ensuring the quality of product shipment. The method of the present invention can realize automated testing and effectively save labor costs.

[0064] In a preferred embodiment of the present invention, such as Figure 2 As shown, in response to the completion of each firmware update for the data processor, diagnostic tests are performed on each component within the data processor, including:

[0065] Check whether the configuration information and health status of the data processor are normal;

[0066] In response to the normal configuration information and health status of the data processor, check whether the consistency of the data processor's firmware and component configuration is correct;

[0067] In response to the consistency and correctness of the firmware and component configuration of the data processor, the alarm thresholds in the data processor's BIOS options are modified to the default values, and the DPU's BIOS setup options are modified to lower the alarm thresholds in order to expose more problems during stress testing and improve diagnostic quality. Modifications are made to options such as memory ECC threshold and PCIE CE threshold.

[0068] After the various alarm thresholds in the data processor's BIOS options have been modified, the CPU stress test of the data processor is performed. After the CPU stress test is completed, the configuration information and health status of the data processor are checked to see if they are normal. The power consumption test can be performed using the PTU tool (PTU-Y-CT 8-T60). After the test is completed, check the test results.

[0069] In response to the normal CPU stress test and the normal configuration information and health status of the data processor, a power-on cycle test of the data processor is performed for the first threshold number of times, and the configuration information and health status of the data processor are checked after each power-on cycle test.

[0070] In response to the normal power-on / off cycle test and the normal configuration information and health status of the data processor, a second threshold number of reboot cycle tests are performed on the data processor, and the configuration information and health status of the data processor are checked after each reboot cycle test.

[0071] In response to the normal reboot cycle test and the normal configuration information and health status of the data processor, a mixed stress test is performed on the memory and CPU of the data processor. After the mixed stress test is completed, the configuration information and health status of the data processor are checked to see if they are normal. The mprime tool can be used for CPU stress test and the stressapp tool can be used for memory stress test.

[0072] In response to the normal performance of the hybrid stress test and the normal configuration and health status of the data processor, stress test the hard drive of the data processor, and check whether the configuration and health status of the data processor are normal after the hard drive stress test is completed. The fio tool can be used to stress test the hard drive of the DPU.

[0073] In response to the normal hard drive stress test and the normal configuration information and health status of the data processor, a storage performance test is performed on the data processor. After the storage performance test is completed, the configuration information and health status of the data processor are checked to see if they are normal. The storage performance test includes DMA test and DDR test.

[0074] In response to the normal performance of the storage test and the normal configuration information and health status of the data processor, a stress test is performed on the network card of the data processor, and the configuration information and health status of the data processor are checked after the network card stress test is completed.

[0075] In response to the network card stress test being normal and the data processor's configuration information and health status being normal, the alarm thresholds in the data processor's BIOS options are modified back to their original values.

[0076] In response to the completion of various alarm threshold modifications in the data processor's BIOS options, the connectivity between the data processor and the server is detected;

[0077] In response to the normal connectivity between the data processor and the server, the system collects and outputs the data processor's profile information. This testing process includes testing of all components within the DPU. These tests can be performed automatically. If any test fails to meet requirements, an alarm is triggered and a test report is output. This testing improves the diagnostic test coverage of the server and data processor, further ensuring product quality and effectively saving labor costs.

[0078] In a preferred embodiment of the present invention, detecting whether the configuration information and health status of the data processor are normal includes:

[0079] The configuration information of the data processor is checked, including whether the model, quantity and parameters of the CPU, memory and hard drive of the data processor are normal, and whether the network card model, network card parameters and number of network ports of the data processor are normal.

[0080] Checking the health status of the data processor includes verifying the normality of the BMC SEL logs, BMC sensor information, system logs, and PCIe device bandwidth. This includes checking for alarms, errors, and failures in the DPU BMC SEL logs; verifying the normality of temperature, voltage, and power information in the BMC sensor information; inspecting demsg, messages, and mcelog in the DPU OS logs; and checking the PCIe device bandwidth.

[0081] In a preferred embodiment of the present invention, in response to the normal configuration information and health status of the data processor, detecting whether the consistency of the firmware and component configuration of the data processor is correct includes:

[0082] Use the configuration files of a preset number of data processors with the same configuration in the same order as the baseline configuration files;

[0083] The configuration files of the remaining data processors in the order are compared with the baseline configuration file. The file systems (FW) and component configurations of DPUs with the same configuration in the same order are identical. Therefore, the configuration of the first three DPUs can be used as a baseline to generate the order's baseline configuration file, which is then compared with the configuration files of the other DPUs in the order.

[0084] In a preferred embodiment of the present invention, in response to the storage performance test being normal and the configuration information and health status of the data processor being normal, a stress test is performed on the network card of the data processor, and after the network card stress test is completed, the detection of whether the configuration information and health status of the data processor are normal includes:

[0085] Use the two ports of the data processor's network card as the server and client respectively;

[0086] Use the iperf tool to perform a flow test on the two ports and compare the test results with the standard values.

[0087] In a preferred embodiment of the present invention, in response to the completion of modifications to various alarm thresholds in the BIOS options of the data processor, detecting the connectivity between the data processor and the server includes:

[0088] Connect the management port of the server BMC to the network port of the data processor;

[0089] Set the IP address and routing of the data processor's network port and the server BMC's management network port to static IP addresses on the same network segment;

[0090] Ping the static IP address of the BMC server's management port from the data processor's system.

[0092] The stress test of direct memory access by the data processor on the server side has passed, and the configuration information and health status of the data processor have been checked to see if they are normal.

[0093] If the data processor's configuration information and health status are normal, a test report will be output.
