Worked on enhancing portability, performance, and build efficiency across the au-ts/sddf and au-ts/lionsos repositories. Addressed cross-compiler compatibility in C by inlining header function declarations, reducing runtime overhead and compilation errors between gcc-15 and clang-19. Improved network driver development by ensuring unique NIC naming and per-NIC hash files, preventing configuration conflicts. Fixed QEMU I2C misconfigurations by explicitly disabling or setting I2C to None. Modernized the Makefile build system using Makefile scripting, enabling parallel updates and clarifying CFLAGS, while refactoring for maintainability. Added static inline directives to header-scope functions, suppressing compiler warnings and improving compile-time performance.
