DeltaOS

A hobby desktop-oriented operating system for AMD64, written in C and x86 assembly with a UEFI bootloader and a monolithic object-based capability-oriented (Currently it's basic but will be expanded) kernel

What it does

• Boots via UEFI with a custom bootloader
• Preemptive multitasking with a RR scheduler
• Virtual memory with paging
• Dynamically linked userspace
• Shell with basic commands (dir, read, echo, cd, pwd)
• Framebuffer graphics and a window manager (WIP)

Building

You need:

• GCC (x86-64 cross-compiler or native)
• NASM
• GNU Make (BSD make WILL NOT work)
• mtools
• QEMU + OVMF (for running)

make        # build everything
make run    #run in QEMU

Status

It boots, runs programs,has some drivers and has a working shell. The window manager exists but is incomplete.

Goals (Roughly in order but not):

• A basic true GPU driver
• USB support
• Flesh out userspace libc fully
• Finish the coreutils
• Expand the Init system
• Flesh out the capability system
• AArch64 support (Later down the line)

Not promises just where we're probably headed
