Public review of Fast Track extension Zihintntl
We are delighted to announce the start of the public review period for the proposed Fast-Track extension Zihintntl to the RISC-V ISA. This extension adds non-temporal locality hints, which affect the performance characteristics of memory-access instructions.
The review period begins today, February 14, 2023, and ends on March 31, 2023.
This extension is part of the Unprivileged Specification.
These extensions are described in the PDF spec available at https://drive.google.com/file/d/1QfGFllFivV1cVM899TCRMfpBNwhhZjWp/view?usp=share_link which was generated from the source available in the following GitHub repo: https://github.com/riscv/riscv-isa-manual
To respond to the public review, please either email comments to the public isa-dev mailing list or add issues and/or pull requests to the RISC-V ISA Manual GitHub repo, https://github.com/riscv/riscv-isa-manual. We welcome all input and appreciate your time and effort in helping us by reviewing the specification.
During the public review period, corrections, comments, and suggestions, will be gathered for review by the Unprivileged Spec ISA Committee. Any minor corrections and/or uncontroversial changes will be incorporated into the specification. Any remaining issues or proposed changes will be addressed in the public review summary report. If there are no issues that require incompatible changes to the public review specification, the Unprivileged ISA Committee will recommend the updated specifications be approved and ratified by the RISC-V Technical Steering Committee and the RISC-V Board of Directors.
Thanks to all the contributors for all their hard work.
Vice-Chair, Privileged ISA Committee
