An open, rolling Linux distribution project for RISC-V

openRuyi is an open source Linux distribution, initiated and long-term maintained by Institute of Software, Chinese Academy of Sciences, to provide a technical foundation for the RISC-V software ecosystem and real-world adoption.

Designed natively for RISC-V, it integrates new RISC-V features early and helps move them upstream, giving developers and industry partners a practical platform to build, validate, and deliver RISC-V software.

• Rolling releases for real-world development and validation
• Early integration of new RISC-V features and upstream collaboration
• Ongoing optimization for cloud-native, AI, and modern Linux systems
• Strong focus on performance, security, and compatibility

• RVCK RISC-V Common Kernel Project
• openRuyi-Tutorials Beginner-friendly learning materials and hands-on examples for the RISC-V Linux ecosystem.
• RuyiAI AI System Software Stack for RISC-V Architecture
• RuyiSDK A product plan for an all-in-one RISC-V integrated development environment.

We welcome hardware vendors, upstream developers, maintainers, researchers, and open source contributors working to advance the RISC-V software ecosystem together.
