Titanos an exercise in writing OS kernel in Rust programming language.

Titanos

Titanos is an exercise in writing a kernel in Rust programming language.

Immediate goal is to complete basic functionality targeting ARMv8 (aarch64) and Vexpress board emulated by Qemu as a testing platform.

Everything is developed under Linux.

See status page for project status.

Building

Follow .travis.yml to understand how to set up toolchain and external requirements.

• make builds everything
• make run to start the kernel inside Qemu
• make debug to start the kernel inside Qemu waiting for GDB connection
• make gdb to connect to Qemu instance started by make debug
• make objdump to dump assembler from the binary

To build in release mode, use export RELEASE=1.

Design

Components:

• src/: source code
• rt/: basic C/ASM runtime
• titanium.rs: Titanos is based on this collection of low-level macros, functions and constants that can be reused by other software targeting bare-metal development in Rust.
• arm_pl011.rs - Titanium.rs based PL011 uart driver.
