Abstract

The invention discloses a linux-based PCIE error processing method and system; the method comprises the following steps: making statistics on occurrence frequency of event types of each error event in a PCIE event source; if the event type with occurrence frequency bigger than N is detected in a first preset period, tagging the error event corresponding to the event type with occurrence frequency bigger than N as a PCIE fault format event, wherein N is a positive integer; if the event type of the PCIE fault format event is determined as a non-correctable error, resetting a PCIE link corresponding to the PCIE fault format event. The method can make classification statistics on error events in the PCIE event source, and can make corresponding treatments, thus ensuring linux PCIE error events to be corrected processed, and reducing system unreliability caused by PCIE faults.

Description

technical field [0001] The present invention relates to the technical field of error diagnosis, more specifically, to a processing method and system based on PCIE errors in linux. Background technique [0002] With the progress of the times, the rapid development of the Internet, and the improvement of people's living standards, computers have become an indispensable part of people. No matter in work, study or life, computers are inseparable. It stores important data and also Complicated calculations can be performed. The PCIE bus in the computer provides various services as an I / O interface. The PCIE bus has the characteristics of high performance and high bandwidth, and can provide network services, storage services, etc. Therefore, the reliability of the PCIE bus is an important part of the reliability of the computer system. Once an error or failure occurs in the PCIE, the system cannot provide reliable services. [0003] Therefore, how to process the PCIE error event...
