Concise monthly summary for 2026-05 focused on delivering performance-oriented LSX optimizations for Loongson hardware across two repos (llama.cpp and ggml). Emphasizes features delivered, impact on ML workloads, and the technical skills demonstrated.

Monthly summary for 2025-11 focusing on LoongArch quantization fixes across llama.cpp and ggml, delivering cross-repo stability and performance improvements for quantized models.

June 2025 focused on improving relocation correctness for the LoongArch target in llvm/clangir. Delivered a critical bug fix for cross-section relocation handling in the LoongArch Assembler, addressing scenarios with linker relaxation enabled or disabled. Introduced isPCRelFixupResolved to determine PC-relative fixup resolution and refined the addReloc logic to either record or resolve directly based on section context, significantly boosting correctness and reliability of relocation processing.

April 2025: Delivered a critical stability patch for ONNX Runtime on LoongArch by fixing a strict aliasing warning and correcting the transpose store operation. This patch enhances correctness and reliability of matrix operations, aligns with MLAS optimizations, and reduces production risk on LoongArch deployments. The change is tracked under commit c29c9b5a33afe01b2b1befd43005bc4e75fa0181 (Fix warning and fix transpose store op for LoongArch) as part of (#24578).

February 2025 monthly summary highlighting key deliverables across ggml-based repos. Delivered LoongArch performance optimizations in llama.cpp and whisper.cpp with enhanced floating-point conversions, extended integer handling, and accelerated vector dot products across multiple quantization schemes. Addressed build warnings on LoongArch CI, improving CI reliability. Result: faster on-device inference and better efficiency for quantized workloads, with cross-repo consistency and maintainability improvements.
