Worked on the tenstorrent/tt-kmd repository to enhance kernel memory management compatibility, focusing on long-term maintainability. Addressed a kernel upgrade challenge by replacing zap_vma_ptes with zap_special_vma_range to support Linux kernel 7.1.0, while introducing a backward-compatibility macro to ensure seamless operation with older kernel versions. This update reduced risk during future kernel upgrades and stabilized the memory management path. The work involved C programming and kernel development, emphasizing careful code review and maintainability. By capturing changes in a precise, review-friendly commit, the developer improved codebase resilience and minimized maintenance burden, contributing to the ongoing stability of kernel memory management.
