Lixu Xu developed comprehensive usage documentation for the OpenXiangShan/GEM5 repository, focusing on integrating NEMU with XS-GEM5. The work detailed setup procedures, environment configuration, and workload generation, aiming to streamline onboarding and improve reproducibility for users deploying NEMU-based GEM5 workflows. Leveraging skills in Linux, RISC-V, and technical writing, Lixu consolidated and aligned documentation with current tooling to support faster test cycles. The documentation, written in Markdown, addressed common setup challenges and clarified process steps, reducing setup time for new users. While no bugs were fixed, the contribution demonstrated depth in system setup and workflow optimization within the project.
