Worked on a comprehensive modernization of the Display Controller Macro subsystem within the torvalds/linux repository, focusing on the Linux DRM stack’s DISPC component. The project involved refactoring register access macros using C, transitioning from legacy FLD_* macros to FIELD_* and GENMASK, and adopting mask-based REG_GET and REG_MOD patterns for safer, more consistent device driver development. Unused and obsolete code was removed to streamline maintenance, while explicit field masks were defined and documented to enhance code readability and correctness. This effort established a cleaner, more maintainable display path, aligning the graphics driver codebase with modern Linux kernel development practices.

Aug 1, 2025August 2025: Delivered a major Display Controller Macro Modernization and Cleanup for the Linux DRM stack (DISPC) in torvalds/linux. Implemented a broad refactor to modernize register access macros, switched to mask-based operations, migrated from legacy FLD_* macros to FIELD_* and GENMASK, removed unused code, and defined explicit field masks for readability and maintainability. The work was executed through a sequence of commits that progressively converted accessors to macros, moved REG_GET/REG_MOD to mask-based patterns, and established explicit field masks, providing safer and clearer code for the display path and setting a solid foundation for future improvements.
