[virtio-dev] [RFC] virtio 1.3 schedule

[virtio-dev] [RFC] virtio 1.3 schedule

[Cornelia Huck]

The virtio 1.2 spec has been released on July 1st, 2022, so I think we
should come up with a plan for the 1.3 release. Given that it took us
several months last time, we need to think about declaring freeze during
(northern hemisphere) summer if we want to have a release ready before
the end-of-year holiday season starts.

We have some things currently under discussion/review that we should
still consider for 1.3:

- vq index etc. naming cleanup
- admin vq
- virtio-video
- some things we deferred for 1.2 (see
  https://github.com/oasis-tcs/virtio-spec/issues?q=is%3Aissue+is%3Aopen+label%3Adeferred-in-v1.2-csprd01)
- other things that are not on my personal list (please mention whatever
  you think is important)

Please also keep in mind that 1.3 will not be the last virtio release,
and many projects like Linux or QEMU consider features stable and ready
for inclusion once the spec has hit the git tree, but not neccessarily a
virtio spec release.

That said, let me propose the following timeline:

- July 1st 2023: enter feature freeze; all proposed changes must at
  least have an open github issue that refers to a proposal on-list
- August 1st 2023: enter change freeze; everything needs to have been
  voted upon (i.e. we can start with preparations for a release like
  compiling the change log)
- at the same time, fork virtio-next, which can be used for development
  while we're working on the release
- August/September 2023: prepare draft, initiate initial voting etc.
- by September/October 2023: have the final 1.3 spec ready, voted upon,
  and released
- virtio-next can be merged into mainline, and we continue with business
  as usual

Thoughts? We might want to move things a tad earlier, but I don't think
we should push the schedule out much further.

Please included transitional VF device support to the list whose proposal is already in progress.
It has matching github issue.

Sounds good to me. If the date is earlier then it will be necessary to
scrutinize the list of features for 1.3 and think hard about which ones
fit, but freezing on July 1st sounds realistic to me.

Hmm looks like you forgot a 30 day the public review period (or is that
included in the "etc"? ).  During this period we will likely receive
review comments which we have to address. Should the changes turn out to
be material, another public review period will be required.
Let's spell it out please.

Yeah, that's what I meant with "etc"... let's make this:

- August 2023: prepare draft, aim to have it ready and voted upon by
  August 31 the latest (preferrably earlier)
- September 2023: public review period (30 days)
- October 2023: another public review period, if needed; otherwise, get
  comittee specification ready and voted upon
- October (maybe November, if we're running late) 2023: virtio 1.3
  released

The most important dates are feature freeze on Jul 1 and change freeze
on Aug 1, I guess; for the rest, we depend on whether people are out on
PTO, which kind of feedback we get, etc. -- but as long as we release
1.3 in 2023, I'll be happy enough.

We have two extension features that has gone through several reviews and are in advance stage (and also late) for 1.3. :)

1. inner hash v19, rolling to v20 anytime this week. 1 Patch.
[1] https://lists.oasis-open.org/archives/virtio-comment/202306/msg00490.html

2. first user of aq for legacy access at v7.
2 patches. First 2 are Fixes.
[2] https://lists.oasis-open.org/archives/virtio-comment/202306/msg00491.html

Both need few more days of review and vote.
Shall we please have few days in July for them so that it can be part of 1.3? 
or whole July is needed to prepare the draft spec?

I think it's not too bad, projects that do releases every couple of
months can afford to be strict, we do them ones a year and a half
it makes sense to be flexible.

Yes, my only concern is to avoid slipping too badly -- and the "feature
freeze" period was actually intended to give us some time to wrap up
outstanding features.

For the inner header hash, I see there's already an issue (#173), so
it's good. I have not followed the aq legacy access feature -- if
everyone agrees that we should be able to vote on it in July, we should
have an issue for it as well (I cannot find one just by looking at
titles.)

Any other features that people are aware of?

Was hoping for virtio-can but it looks like it's still in RFC stage.
I am guessing the spec should be copied to people who reviewed
the driver.
