Harini Kumaran modernized constants usage in the intel/compute-runtime repository by refactoring system interfaces to use inline constexpr and std::string_view within the L0 namespace. Focusing on C++ and low-level programming, Harini centralized constant declarations across firmware, global operations, and PCI configurations, replacing macro-driven patterns to improve maintainability and consistency. The work aligned the codebase with modern C++ practices, reducing reliance on macros and preparing the groundwork for future performance enhancements. This targeted refactor in level_zero/tools demonstrated a thoughtful approach to system management and code quality, addressing technical debt and enabling more efficient future development within the project.
