Worked on enhancing device discovery in the u-root/u-root repository, focusing on improving the FindDrive tool for Linux environments. Addressed the challenge of reliably identifying block devices within nested PCIe topologies by shifting from prefix to substring matching of BDFs in device paths. Introduced Linux-specific file naming and implementation refactors to align with system conventions, increasing maintainability and traceability. Expanded automated test coverage by adding targeted cases for complex PCIe scenarios, ensuring robust validation using Go’s testing framework. Leveraged skills in Go, Linux development, and system programming to deliver a feature that improves system initialization and device enumeration accuracy in production deployments.
