# Chroma
|
|
The Chromatic OS
|
|
|
|
## About
|
|
Chroma is an x86_64 kernel, soon to be Operating System.
|
|
It uses the [bootboot](https://gitlab.com/bztsrc/bootboot) bootloader.
|
|
|
|
## Features
|
|
It can currently:
|
|
- [x] read keyboard input
|
|
- [x] draw to the screen, including text and basic images.
|
|
- [x] output audio over the PC Speaker
|
|
- [x] manage physical memory
|
|
- [ ] manage virtual memory
|
|
- [ ] switch to ring 3
|
|
- [ ] switch tasks
|
|
- [ ] schedule tasks
|
|
- [ ] handle processes and threads
|
|
- [ ] handle mouse input
|
|
- [ ] display a basic 3D object
|
|
- [ ] display a basic 3D world
|
|
- [ ] display a basic 3D world *in VR*
|
|
|
|
Once we reach this point... well, the world is our oyster.

## Building
|
|
|
|
Chroma can be built on Windows or Linux.
|
|
|
|
### Windows
|
|
I (Curle) use Windows for developing Chroma.
|
|
Simply have an [x86_64-elf-gcc](https://github.com/lordmilko/i686-elf-tools) and ld (included!) in your PATH, and run setup.bat.
|
|
You will need to use WSL to generate the iso; copy the created kernel.elf file to iso/boot/ as `initrd`, and run `grub-mkrescue -o chroma.iso iso/`.
|
|
A new system is in the works for creating this ISO natively on Windows.
|
|
|
|
The generated ISO works in QEMU, or on a physical test device (unlike a lot of other hobby OSes!)
|
|
|
|
### Linux
|
|
|
|
The system for linux is a lot easier, but you *do* need an x86_64-elf-gcc cross compiler. You can get one from the AUR on Arch-based distros (like Manjaro), or make one yourself using [the OSDev Wiki guide](https://wiki.osdev.org/GCC_Cross-Compiler)
|
|
Simply run the `init.sh` to generate a makefile, then `make` to create the kernel.elf file.
|
|
Same thing applies as Windows now - copy the kernel.elf file to iso/boot/ as `initrd` and run `grub-mkrescue -o chroma.iso iso/`.
