Show HN: Xv6OS – A modified MIT xv6 with GUI I've been working on a hobby project to transform the traditional xv6 teaching OS into a graphical environment. Key Technical Features: GUI Subsystem: I implemented a kernel-level window manager and drawing primitives. Mouse Support: Integrated a PS/2 mouse driver for navigation. Custom Toolchain: I used Python scripts (Pillow) and Go to convert PNG assets and TTF fonts into C arrays for the kernel. Userland: Includes a terminal, file explorer, text editor, and a Floppy Bird game. The project is built for i386 using a monolithic kernel design.
