Submissions of extensions to the Unpriv and Priv ICs for official Architecture Review and for Opcode/CSR Assignment Review (and official allocation) should be emailed to  tech-opcode-and-consistency-reviewarch-review@lists.riscv.org.  A row for your submission must also be added to the bottom of the Arch Review Status table below, and please fill in all fields except for the Status/ETA field. 

Once arch review results have been provided back to the TG, spec changes corresponding to requested changes/corrections/etc. do not need to be re-reviewed.  But any other substantive post-review architectural changes must be presented back to the Arch Review committee (using the above email) for approval.  Ideally there should not be any such changes, but a simple email summarizing the what and why of any changes is sufficient.

In addition to the extension spec, please submit information about the PoCs and about utility/efficiency (although we don't need all the gory detail - a paragraph or so for each can be fine).  For items considered to not be consequential, a sentence or so explaining why should suffice.
