To respond to the public review, please either E-mail comments to the
public RISC-V isa-dev mailing list,
or add issues to the RISC-V AIA GitHub repo:
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 AIA Task Group. 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 Privileged Software HC 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, AIA Task Group
