In February 2026, Maciej Sobkowski focused on enhancing instrumentation within the Zephyr4Microchip/zephyr repository by refactoring the zaru script using Python. He removed code duplication and transitioned the tracing output from the Perfetto format to Trace Event, improving both the clarity and maintainability of the instrumentation code. This upgrade facilitated better compatibility with trace viewers and streamlined future performance analysis. Although no bugs were fixed during this period, the work demonstrated depth in scripting and performance analysis, laying a foundation for easier onboarding and faster enhancements. The changes were reviewed and signed off by multiple contributors, reflecting collaborative engineering standards.
