A toy OS

Qux is a toy operating system for x64 written in zig.

Build and run

• can only be built in Linux on x64 with grub installed.
• the kernel directory contains the kernel source code
• the boot directory contains some utility for bootstrap. steps to build:
  • run zig build under kernel to build the kernel
  • mkimg test.img make a disk image named test.img with grub installed to boot the OS with multiboot2.
  • build build everything under boot directory and copy the kernel to the disk image built above and start QEMU to run it

What's implemented

memory management
basic process management/scheduling
basic ATA driver
ext2 file system, read only so far
syscalls, trying to implement Linux syscalls, so that userspace programs for Linux could hopefully run on Qux
basic ELF loader
can run doom(doomgeneric), kind of :), key handling is still to be done

TODO

network stack
SMP support
more syscalls
port some usefull userspace programs
