AI Technical Summary

Technical Problem

In the process of fixing Linux kernel configuration items, existing technologies have problems such as complex configuration constraints, difficulty in error location, reliance on manual experience for repair, high iteration costs, insufficient stability assurance, and lack of engineering-based methods for locating cross-version regressions.

Method used

Candidate configuration files are generated using randomization or batching strategies. A closed-loop approach is adopted, combining reproducible startup testing, Kconfig semantic constraint modeling, automated repair decision-making, and stability verification. Automated repair is achieved through structured log parsing, unified dependency graph construction, and configuration item classification.

Benefits of technology

It significantly improves the efficiency and stability of configuration item repair, reduces reliance on manual experience, reduces redundant attempts, increases repair convergence speed, and reduces runtime instability risks through coverage-guided kernel fuzzing, while providing an engineering-based path for cross-version regression localization.

Abstract

This invention discloses a Linux kernel boot testing and configuration consistency intelligent repair method for configuration item repair, comprising: collecting compilation logs, boot logs, and running status; segmenting, pattern matching, and field extraction of the logs to standardize error information into structured error entries, and distinguishing between dependency missing, mutual exclusion conflict, and other compilation failure categories; preprocessing and parsing the Kconfig file to extract configuration item attributes and constraints, constructing a unified dependency graph, and generating a configuration item metadata table; classifying and labeling configuration items based on metadata and calculating criticality scores; generating repair actions based on structured error entries, the unified dependency graph, and criticality scores, and iteratively executing them, with recompilation and reboot verification after each iteration until a compileable and bootable repaired configuration file is obtained or a preset iteration limit is reached; this invention improves cross-version adaptation and problem closure efficiency.
