Dec 1, 2024December 2024 monthly summary for OpenXiangShan/XiangShan focused on hardware-prioritized performance improvements in CSR read paths. Key feature delivered: CSRR Instruction Reordering for CSR Reads, enabling most CSR reads to be issued and executed out-of-order and introducing an in-order list for CSR reads sensitive to user-level instructions without fences. This reduces stalls and improves pipeline efficiency for read-only CSR operations. Commit reference for the change is 075d493727e8b112c3e7bd97b06b5e1d167aba73. No major bug fixes were documented this month.
