PCIe Error Reporting Filtering for Debugging Complexity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current PCIe device error reporting systems only display error log data types, lacking information on error triggering events, which increases debugging complexity for engineers.
Innovation Solution
The PCIe device error reporting optimization method and system acquire advanced error reporting data, execute a removal detection process to determine if the device is plugged into a connector, and filter error log data to exclude irrelevant events, allowing only relevant error data to be transmitted to the BMC and ACPI.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all error log data is transmitted to BMC and ACPI, then complete error information is provided, but debugging complexity increases due to irrelevant error messages
Solution Approach 1:
The patent extracts and removes irrelevant error log data (specifically unplugging events) from the error reporting stream. The processor identifies error logs corresponding to unplugging events and filters them out before transmission to BMC and ACPI, leaving only relevant error information that aids debugging.
Solution Approach 2:
The patent segments the error log data transmission process into two distinct paths: one for plugged devices (transmit all error logs) and one for unplugged devices (filter out unplugging events). This segmentation allows selective filtering based on device connection status, reducing unnecessary information while maintaining completeness where needed.
2Productivity
If error filtering is implemented, then debugging efficiency is improved, but system complexity increases due to additional processing requirements
Solution Approach 1:
The system performs self-service by automatically detecting device plugging status and autonomously filtering error logs without external intervention. The processor executes the removal detection process and automatically determines which error logs to filter, eliminating the need for manual configuration or complex external filtering mechanisms.
Solution Approach 2:
The patent implements preliminary action by executing the removal detection process before error log transmission. The system proactively identifies unplugged devices and pre-filters their error logs, so that only relevant errors are transmitted to BMC and ACPI, improving debugging efficiency before issues are reported.
3Loss of information
If removal detection process is added, then irrelevant error messages are filtered, but processing time increases
Solution Approach 1:
The patent replaces complex mechanical or manual error filtering mechanisms with an automated electronic detection and filtering system. The processor electronically executes the removal detection process and automatically filters error logs based on device status, reducing processing time compared to manual or mechanical approaches.
