Worked on the hermit-os/kernel repository to enhance the reliability of memory management diagnostics, focusing on debugging support for huge pages. Addressed a bug in the page table entry debug function by updating the address extraction logic, ensuring accurate retrieval of physical addresses when large page sizes are used. This targeted patch improved the consistency and clarity of debug output across both standard and huge pages, reducing diagnostic noise and deployment risk. The work demonstrated strong skills in low-level programming, memory management, and operating system development using Rust, with a careful approach that minimized regression risk and maintained clear code boundaries.
