Over a two-month period, Oliver Steffen enhanced boot-time reliability and development workflows across acidanthera/audk and microsoft/mu_tiano_plus. He addressed network boot sequencing by ensuring network modules initialize only after virtio-rng is available, reducing startup flakiness through dispatcher reruns during the BDS phase. In acidanthera/audk, he improved code coverage collection by adding LCOV v2 compatibility and aligned local development with CI using Fedora 40 containers. For microsoft/mu_tiano_plus, he consolidated TPM2 PTP API headers to streamline code organization. His work demonstrated depth in C and Python, leveraging skills in embedded systems, firmware development, build systems, and containerization.
