Gila v0.2.0 - a Rust Microkernel

Gila is a Rust microkernel OS, inspired by the Xinu embedded OS. It will hopefully be capable of multitasking some day. I do not intend for Gila to be POSIX-like or compatible.

Work In Progress

Gila does nothing at all right now. Check back later. Or contribute.

Navigating

• boot.rs: Handles bootloader handoff. Gila uses Limine. Other bootloaders are NOT supported.
• display.rs: Handles text-mode display via the VGA buffer.
• lib.rs: Glue to make all files accessible from main.rs.
• main.rs: The entry point that gets called by the bootloader.
• memory.rs: Types relating to memory regions and allocation.
• panic.rs: The panic handler and associated functionality.
• process.rs: Process types and functions.
• resources.rs: Resources that are accessible from multiple parts of the code.

Building and running

To build an ISO image that you can boot, there are several prerequisites:

• limine command installed
• xorriso command installed

Then run the build_iso.sh script. It will generate gila.iso.

Running the kernel requires qemu-system-{ARCH}.

You can install all these dependencies automatically by using nix-shell and supplying shell.nix as an argument.
