RISC-V Architecture Adaptation Knowledge Base

A guide for software developers and architecture adaptation engineers on adapting to the RISC-V architecture.

What?

This knowledge base aims to summarize common issues and solutions when adapting general software to the RISC-V architecture.

Key features of this knowledge base include:

End-to-End Coverage: Encompassing multiple stages such as software coding, compilation, building, and testing, covering the entire software development process.
Multiple Programming Languages: Inducing common architecture-related code patterns for various programming languages, with a focus on C/C++.
Example Analysis Guidance: Using a large number of actual software project codes, guiding developers to understand software adaptation knowledge through example analysis.
Encouraging Open Collaboration: Following the MulanOWL BY-SA license for open sharing. Encouraging suggestions and contributions while referring to this knowledge base.

As an open and freely usable instruction set architecture, RISC-V has garnered widespread attention since its introduction. Numerous RISC-V architecture-based development boards and hardware devices have been introduced globally for different scenarios. However, the RISC-V architecture is still in its early stages, with the software ecosystem needing further development, and developers requiring time and effort to learn.

This knowledge base aims to formalize and document the explorations and efforts made by predecessors in the early stages of RISC-V architecture development, reducing the learning curve and difficulty for developers and accelerating the improvement of the RISC-V software ecosystem.

How?

If you are one of the following:

Software Development Engineer: Your software currently runs on platforms with mainstream architectures, but you are facing difficulties or don't know where to start when trying to run it on the RISC-V architecture.
Software Migration Engineer: You are adapting software to the RISC-V architecture but are unsure about what needs to be modified and how.
Software Tester: You have conducted software testing on platforms with other architectures and now want to understand the essentials of software testing on the RISC-V architecture.
Beginner and Novice Developers: You want to understand various aspects of the RISC-V architecture and how to make software support multiple architectures such as RISC-V.

Then, this knowledge base can:

Serve as a tutorial to quickly help you understand and master software development for the RISC-V architecture.
Act as a reference book to assist you in solving challenging issues related to software adaptation to the RISC-V architecture.
Provide a set of checklists to guide you through the step-by-step process of adapting software to the RISC-V architecture.
...

Feel free to explore and use the various RISC-V architecture adaptation knowledge contents within this knowledge base in different ways.
