The redshirt operating system is an experiment to build some kind of operating-system-like environment where executables are all in Wasm and are loaded from an IPFS-like decentralized network.
docs/introduction.md file for an introduction.
How to test
Important: At the moment, most of the compilation requires a nightly version of Rust. See also #300. Your C compiler must be recent enough to be capable of compiling to WebAssembly. This is for example the case for clang 9. See also #257.
You also need to install the
wasm32-wasi target, as the Wasm programs are compiled for Wasi, and the
rust-src component in order to build the standalone kernel.
rustup toolchain install --target=wasm32-wasi nightly rustup component add --toolchain=nightly rust-src
Building the freestanding kernel is then done through the utility called
cd kernel-standalone-builder cargo +nightly run -- emulator-run --emulator qemu --target x86_64-multiboot2
Short overview of the structure of the repository:
docscontains a description of what redshirt is and how it works. Start with
interfacescontains crates that provide definitions and helpers for Wasm programs to use (examples:
kernelcontains the code required to run the kernel.
kernel-standalone-kernelcontains a utility allowing to run and test the standalone kernel.
programscontains Wasm programs.
