About the xPack QEMU RISC-V

The project​

The xPack QEMU RISC-V project is part of the xPack Reproducible Build Framework and is hosted on GitHub as xpack-dev-tools/qemu-riscv-xpack, part of the xPack Binary Development Tools.

The main goal of this project is to streamline the development of embedded projects. µOS++ is the first cross-platform project to benefit from the xPack tools.

Project history​

The project was created in December 2021, with the initial content copied from qemu-arm-xpack.

May 2022​

The first xPack QEMU RISC-V release was v7.0.0-1.

December 2022​

The project received a significant update by transitioning the build scripts from the cumbersome monolithic XBB Docker images to the more flexible and modular xPacks. XBB version 5.0.0 marked a major milestone for the xPack project, as it was the first self-sustained release. This version enabled the creation of new binary xPacks using existing binary xPacks, eliminating the need for custom Docker images or other compiled tools.

August 2024​

The project underwent a comprehensive restructuring. To streamline the top package.json by showcasing only user-related definitions and concealing build-related ones, all build-related files were relocated to the build-assets folder. Furthermore, the development Git branch was renamed to xpack-development for enhanced clarity.

The web site​

The initial web site was launched in July 2022 as a sub-site in the xPack web site. It used the Jekyll Doc Theme 6.0 by Tom Johnson.

In August 2024, as part of the project restructuring, the website content was migrated from the xPack Jekyll sub-site to a local Docusaurus configuration stored in the website folder. To ensure continuity, HTML <meta> redirects were added to the old pages. Additionally, a GitHub Action was implemented to automatically publish the site upon any pushes to the website Git branch.
