PROFILE

Marcin Wcisło

Worked on the ctrliq/kernel-src-tree repository to enhance kernel self-test infrastructure, focusing on documentation, onboarding, and test reliability. Consolidated and clarified kselftests documentation, introduced directory-specific READMEs, and improved Makefile logic using Shell and Makefile scripting to ensure accurate test discovery. Developed a comprehensive kernel test documentation suite, including a Rocky Linux test availability matrix, to support cross-version and cross-platform validation. Authored detailed guidance for Breakpoints KTests, covering compilation and troubleshooting for x86_64 and arm64. These efforts improved test reproducibility, reduced onboarding friction, and streamlined troubleshooting, demonstrating depth in build systems, kernel testing, and documentation best practices.
