Worked on stabilizing keyboard input for the NVIDIA/edk2-platforms repository by addressing a bug in the VirtualKeyboardDxe driver. Focused on improving key registration and handling for function and control keys during boot, the developer iterated through scan code and Unicode ranges to ensure F1-F12, Backspace, and Tab were correctly processed. By initializing UnicodeChar to CHAR_NULL instead of SCAN_NULL, the fix reduced the risk of KeyBuffer corruption and undefined behavior. Leveraging expertise in C, driver development, and embedded systems, the work enhanced boot-time keyboard reliability and maintainability, with all changes tracked through targeted commits for future traceability.
