RISC V CMO proposal - riscvarchive/riscv-CMOs-discuss GitHub Wiki

This proposal for CMOs was prepared by Andy Glew, and is a start for discussion of the CMO TG.

There may be other proposals from opthe TG members. TBD: copy here and/or link there.

The https://github.com/riscv/riscv-CMOs/ repo and wiki were forked from a personal repo and wiki https://github.com/AndyGlew/Ri5-stuff that also contained non-CMO stuff.

"Released" Proposal - what you are probably looking for

As of Sept 2020 there is not really a "release" procedure. PDF and HTML are preparted in an offline clone of the repo+wiki, and pushed to GitHub.

TBD: imitate the main and V specs, automatically generating PDF and HTML on the GitHub servers on checkin/push. (Not just push, as long as we continue to use a proposal embedded in the wiki.)

TBD: fix the tools so that the work on systems other than Andy Glew's personal PC with cygwin.

Work in Progress (WIP)

• mailing list running - lots of traffic
