PROFILE
Xiaokun-pei
Pei Xiaokun worked on the OpenXiangShan/XiangShan repository, focusing on enhancing the robustness of memory address translation in virtualized environments. He addressed edge-case faults in the Page Table Walker by refining high-bit checks for guest physical address translation, particularly in Sv39x4 and Sv48x4 modes. Using Scala and leveraging expertise in low-level programming and memory management, Pei aligned GVPN length checks with page table configuration to ensure correctness during the first stage of address translation. His targeted fixes improved system architecture reliability, demonstrated clear code health practices, and contributed to the maturation of low-level memory translation logic within the project.
