Winix is a minimal, hobbyist, educational and UNIX-style Operating System for the Waikato RISC Architecture Microprocessor (WRAMP). It is a hybrid kernel with usability and performance in mind. Winix is mainly inspired by Minix1, which is the OS I learnt when I was in university.
Winix includes full-featured kernel with process and memory management, in-memory file system, exception control and user space bourne shell with interactive command line. Yes, you can even play snake on it by typing snake in the command line
- Kernel Memory Management: virtual memory, page mapping
- Process Management: Kernel thread, process creation
- Exception control and interrupt handler
- In-memory file system that supports most of the POSIX api
- A Bourne shell supporting multiple pipes and redirection
- User memory management: malloc() free()
- User coroutine with
ucontext.hsupport - Stacktrace dump, segfault analysis

Similar to linux kbuild, Winix supports verbose option, you can debug Makefile by setting verbose to 1
make V=1
kprintf() is your friend.
