Worked on enhancing the reliability of performance testing within the linux-riscv/linux repository by addressing issues with flaky test executions. Focused on refactoring shell scripts used in the perf tool test suite, the approach involved converting all relative paths to absolute paths to decouple test execution from the current working directory. This change ensured that script inclusions and command references remained consistent across different environments, reducing the likelihood of test failures due to path discrepancies. Utilized shell scripting, performance analysis, and testing skills to improve the robustness of the testing suite, enabling more dependable performance metrics for ongoing development and decision-making.
