Worked on integrating RV64 JIT support and profiling capabilities into the oneapi-src/oneDNN repository, focusing on backend development and performance optimization. Leveraged C++ and CMake to register JIT code with cpu::jit_utils, enabling JIT dump functionality and enhancing runtime observability for the RV64 backend. Updated build system configurations, including CMakeLists and jit_generator.hpp, to ensure comprehensive profiling readiness and seamless JIT code registration. The work established an end-to-end JIT code path for RV64, allowing for improved performance tuning and backend profiling. No bugs were addressed during this period, with efforts concentrated on feature development and infrastructure enhancements.
