Subject: Public Review for RISC-V Hart to Trace Interface (RHTI) Specification and TrcState Extension

 

Greetings!

We are delighted to announce the commencement of the public review period for the RISC-V Hart to Trace Interface (RHTI) Specification and the TrcState Extension to this.   The RHTI specification is being spun out of the Efficient Trace for RISC-V spec into a standalone spec as a non-ISA fast-track.

This 30-day review period begins today, 15-May-2026, and concludes on 14-Jun-2026.

The source for this document is available on GitHub: https://github.com/riscv-non-isa/hart-trace-interface

The specification document is available for download as a PDF at the following link: https://github.com/riscv-non-isa/riscv-hart-trace-interface/releases/download/v0.9/hart-trace-interface.pdf

How to Provide Feedback:
To participate in the review, you may either:

• Reply to this thread on isa-dev (https://groups.google.com/a/groups.riscv.org/g/isa-dev), and/or
• Submit issues directly on the GitHub repository here: https://github.com/riscv-non-isa/hart-trace-interface/issues

If you experience any difficulty accessing the document or GitHub links, please contact he...@riscv.org or the sender of this message directly. We will be happy to assist you or provide the document in an alternative format upon request.

Your Feedback Matters:
During the review period, we will gather corrections, comments, and suggestions for review by the SoC Horizontal Committee. Minor corrections and non-controversial changes will be directly incorporated. Any unresolved issues or significant proposed modifications will be summarized in the public review report. Provided no major changes are required, the SoC Horizontal Committee will recommend ratification by both the RISC-V Technical Steering Committee and the RISC-V Board of Directors.

We greatly appreciate your contributions and feedback in refining this specification.

Warm regards,

Iain Robertson (Fast-track author, DTPM SIG chair)
