A PCIE device error correction method and device

Abstract

The invention discloses a PCIE device error correction method and device. The method comprises the following steps: connecting to a server with correctable error through an ITP interface, and scanningeach PCIE device of the server; reading a correctable error state in a register of each PCIE device, and determining a PCIE device in which the register having correctable error is located as an error PCIE device; modifying the parameter of the link corresponding to the error PCIE device in the CPU so that the packet damage phenomenon of the error PCIE device does not occur again. The technical proposal of the invention can carry out error correction processing for different PCIE devices or different types of PCIE devices plugged on the server, eliminate correctable errors of the PCIE devices, and maintain stable operation of the server.

Description

technical field [0001] The present invention relates to the field of data transmission, and more specifically, to a PCIE device error correction method and device. Background technique [0002] PCIE is used as the main IO (input output) bus connecting the CPU (central processing unit) and various devices on the server because of its fast speed and high bandwidth. As a standard PCIE device, PCIE (High Speed ​​Serial Computer Expansion Bus Standard) card is widely used and can be plugged into any PCIE slot of the server, so a server can be equipped with multiple PCIE cards. However, there are PCIE cards of multiple formats and channels in the prior art, and various correctable errors (such as compatibility issues) may occur in the process of matching with the server, and the prior art lacks a correctable error Error correction scheme. [0003] There is no effective solution to the problem of the lack of error correction schemes for correctable errors in the prior art. Cont...
