Embodiment 1

[0033] Such as figure 1 As shown, the technical solution of the present invention provides a detection method of PCIe network card error information on the one hand, comprising:

[0034] S101, using the lspci tool to obtain the information of the PCIe device and the PCIe network card of the server product.

[0035] S102. Use the lspci tool to read the first 288 bytes of data in the PCIe configuration space of the PCIe network card.

[0036] S103. According to the first correspondence, judge whether the value of the bit corresponding to the error in the uncorrectable error mask register is 0. If the judgment result is yes, execute step S105; if the judgment result is no, execute step S104.

[0037] S104, set the corresponding bit to 0 through the setpci tool to enable it, and turn to step S102.

[0038]S105, judging whether the value of the bit corresponding to the error in the uncorrectable error status register is 1. If the judging result is yes, go to step S106; if the j...

Embodiment 2

[0061] Such as figure 2 As shown, the technical solution of the present invention provides a detection device for PCIe network card error information on the one hand, comprising:

[0062] The network card information acquisition module 101 utilizes the lspci tool to obtain PCIe equipment and PCIe network card information in the server product;

[0063] Configuration data reading module 102 utilizes the lspci tool to read the data of the first 288 bytes of the PCIe configuration space of the PCIe network card;

[0064] Uncorrectable mask register judging module 103, according to the first correspondence, judges whether the value of the bit corresponding to the error in the uncorrectable mask register is 0, if it is 0, it means that its error is normally obtained, and transfers to If the uncorrectable status register judging module 104 is 1, it means that its error is shielded, and its corresponding bit position needs to be set to 0 by the setpci tool, and then transferred to ...

Abstract

The invention innovatively provides a method and a device for detecting error information of a PCIe network card. according to the first correspondence and the second correspondence, By determining The the corresponding bit value of the uncorrectable mask register, uncorrectable status register, error correctable mask register, the error correctable status register, getting PCIe NIC error information, the invention can effectively solve the problems of poor soldering (such as false soldering) of PCIe slots and components of ancillary circuits on the motherboard or poor network card of PCIe interface, the link connection and data transmission of PCIe interface NIC are unstable, and the bandwidth and the connection speed meet the design requirements of the network card, but the performanceof the link connection and the transmission data of the interface of the network card is greatly degraded, at the same time, various defects of the data link layer and the transaction processing layercan be obtained, the requirement of the shipment is met, and the detection efficiency and the yield of the product are improved.

Description

technical field [0001] The invention relates to the field of test evaluation, in particular to a method and device for detecting error information of a PCIe network card. Background technique [0002] At present, in the server system assembly factory, after the PICe interface network card is assembled, the bandwidth (link width) and connection speed (link speed) of the PCIe network card are generally simply read from the PCIe configuration space, and the PCIe network card is determined to be real-time at this time. Whether it is working in a normal state. However, the PCIe slot on the main board and the components of its auxiliary circuit may cause unstable link connection and data transmission of the PCIe interface network card due to poor soldering (such as false soldering) or poor performance of the PCIe interface network card itself. Sometimes the bandwidth and connection speed meet the design requirements of the network card, but the link connection and data transmissi...
