Kernel\n\n[![Documentation](https://img.shields.io/badge/docs-latest-blue.svg)](https://hermit-os.github.io/kernel/hermit/)\n![License](https://img.shields.io/badge/license-MIT%2FApache--2.0-blue)\n[![Zulip Badge](https://img.shields.io/badge/chat-hermit-57A37C?logo=zulip)](https://hermit.zulipchat.com/)\n[![DOI](https://zenodo.org/badge/DOI/10.5281/zenodo.14645534.svg)](https://doi.org/10.5281/zenodo.14645534)\n\nThis is the kernel of the [Hermit](https://github.com/hermit-os) unikernel project.\n\n## Requirements\n\n* [`rustup`](https://www.rust-lang.org/tools/install)\n\n## Building the kernel\n\nUsually the kernel will be linked as static library to your applications.\n\n- **Rust applications:** Instructions can be found in the [hermit-rs](https://github.com/hermit-os/hermit-rs) repository.\n- **For C/C++ applications:** Instructions can be found in the [hermit-playground](https://github.com/hermit-os/hermit-playground) repository.\n \n\n### Standalone static library build\n\n```sh\ncargo xtask build --arch x86_64\n```\n\nOn completion, the script will print the path of `libhermit.a`.\nIf you want to build the kernel for aarch64, please replace `x86_64` by `aarch64`.\nIf you want to build the kernel for riscv64, please use `riscv64`. \n\n### Control the kernel messages verbosity\n\nThis kernel uses the lightweight logging crate [log](https://github.com/rust-lang/log) to print kernel messages.\nThe environment variable `HERMIT_LOG_LEVEL_FILTER` controls the verbosity. \nYou can change it by setting it at compile time to a string matching the name of a [LevelFilter](https://docs.rs/log/0.4.8/log/enum.LevelFilter.html).\nIf the variable is not set, or the name doesn't match, then `LevelFilter::Info` is used by default.\n\n```sh\n$ HERMIT_LOG_LEVEL_FILTER=Debug cargo xtask build --arch x86_64\n```\n\n## Credits\n\nThis kernel is derived from following tutorials and software distributions:\n\n1. Philipp Oppermann's [excellent series of blog posts][opp].\n2. Erik Kidd's [toyos-rs][kidd], which is an extension of Philipp Opermann's kernel.\n3. The Rust-based teaching operating system [eduOS-rs][eduos].\n\n[opp]: http://blog.phil-opp.com/\n[kidd]: http://www.randomhacks.net/bare-metal-rust/\n[eduos]: http://rwth-os.github.io/eduOS-rs/\n\n## License\n\nLicensed under either of\n\n* Apache License, Version 2.0, ([LICENSE-APACHE](LICENSE-APACHE) or http://www.apache.org/licenses/LICENSE-2.0)\n* MIT license ([LICENSE-MIT](LICENSE-MIT) or http://opensource.org/licenses/MIT)\n\nat your option.\n\n## Contribution\n\nUnless you explicitly state otherwise, any contribution intentionally submitted for inclusion in the work by you, as defined in the Apache-2.0 license, shall be dual licensed as above, without any additional terms or conditions.\n\nThe kernel is being developed on [hermit-os/kernel](https://github.com/hermit-os/kernel).\nCreate your own fork, send us a pull request, and chat with us on [Zulip](https://hermit.zulipchat.com/).\n","funding_links":[],"categories":["Rust"],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhermit-os%2Fkernel","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fhermit-os%2Fkernel","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhermit-os%2Fkernel/lists"}
