Contributed to kernel development on the torvalds/linux and geerlingguy/linux repositories, focusing on RISC-V KVM enhancements and documentation accuracy. Refactored the KVM self-test suite to consolidate RISCV_FENCE macro usage, reducing code duplication and improving maintainability for future architectural changes. Expanded the RISC-V test suite with additional cases, strengthening validation and onboarding for new contributors. Addressed documentation clarity by correcting function references in RISC-V KVM comments, minimizing confusion for maintainers. Work was implemented in C and Makefile, leveraging expertise in system programming, kernel development, and system testing to improve code quality, reliability, and contributor experience across both repositories.
