Gila v0.3.1 - a Rust Microkernel

Gila is a Rust microkernel OS, inspired by microkernel projects such as seL4 and Redox. I aim to implement multitasking, userspace drivers, IPC, and sandboxing. I do not aim to make it POSIX-compatible, but it will likely end up sharing many features with POSIX operating systems. Its design philosophy is focused around simplicity, isolation, modularity, and minimal privilege.

Development

Information on the build system, repo structure, features, configuration options, supported architectures, design philosophies, and more, is available in the docs folder. If you want to build Gila for yourself, consider reading DEVELOPMENT.md for explicit instructions.
