Project Mu Basecore Repository

??? info "Git Details" Repository Url: {{mu_basecore.url}} Branch: {{mu_basecore.branch}} Commit: {{mu_basecore.commit}} Commit Date: {{mu_basecore.date}}

This repository is considered foundational and fundamental to Project Mu. The guiding philosophy is that this any code within this repository should be one or more of the following

  • Part of the build system
  • Common to any silicon architecture
  • Part of the "API layer" that contains protocol and library definitions including
    • Industry Standards
    • UEFI Specifications
    • ACPI Specifications
  • Part of the "PI" layer that contains driver dispatch logic, event/signaling logic, or memory management logic
    • This can also include central technologies like variable services

This repo, and Project Mu as a whole, also include support for Rust code. See the Rust section in the Project Mu features list for more information about how to use it and why Project Mu is adopting Rust.

Please see the Project Mu docs (https://github.com/Microsoft/mu) for more information.

This project has adopted the Microsoft Open Source Code of Conduct.

Releases

It is recommended to consume binaries built from the code in this repo (outside of development purposes) through a versioned release.

Releases are tagged in the repository and are visible in the Releases page. Each release contains release notes describing the changes since the last release with important changes such as breaking changes highlighted.

A semantic versioning process (version is <major.minor.patch>) is followed with the following rules:

  • Major Version

    • A major version change indicates a breaking change. This means that the release is not backward compatible with the previous release. This is typically a change to the API or ABI of a component.

    • The major version in Mu Basecore is broken down into the following components:

      • <Mu Release Version><Major Version>
        • Mu Release Version is 6 digits and corresponds to the edk2 stable tag the Mu release branch is based on.
        • Major Version is 4 digits and tracks the monotonically incrementing major version within the branch.
        • For example, 2022080001 would be the first major version value in the release/202208 branch.

  • Minor Version

    • A minor version change indicates a new feature or enhancement. This means that the release is backward compatible with the previous release but includes new functionality or a major rework of existing functionality.

  • Patch Version

    • A patch version change indicates a bug fix or any other change. This means that the release is backward compatible with the previous release and contains no new functionality.
