Worked on optimizing CCS data migration performance within the linux-riscv/linux repository, focusing on kernel development and performance tuning using C and GPU programming skills. Addressed inefficiencies in the CCS-only data migration path by removing redundant emit_pte() calls, which reduced system overhead and improved migration throughput. The technical approach centered on streamlining the data copy process to enhance efficiency without compromising stability or maintainability. No major bugs were reported during this period, reflecting careful attention to code quality. The work demonstrated a targeted, performance-driven mindset, emphasizing maintainable improvements in kernel-level data migration for RISC-V architectures within a collaborative codebase.
