[virtio] [PATCH 1/2] ccw: be more precise the semantic of revision 1

[Halil Pasic]

Revision 1 of the CCW transport is currently defined as virtio 1.0. This
could become confusing when we bump the version of the virtio
specification to 1.1, in a sense that it could be interpreted like one
can not use any features not part of the 1.0 specification.

So let us try to avoid confusion regarding the semantic of virtio-ccw
revision 1.

Nod. Should I spin a v2 or is it better handled
via fixup by maintainer?

I prefer a respin. How about that jira issue(s)?
You could then also include the # in the patch commit log then.
Just say

VIRTIO-XXXX

in the commit log

[virtio] [PATCH 2/2] introduction: simplify the designation of legacy

[Halil Pasic]

The sentence designating the documents defining what later
became known as the legacy virtio interface had the most
important piece of information placed in parenthesis.

Let's reword this sentence so we avoid using an ambiguous designation
based on a relative anchor (i.e. 'earlier drafts of this specification')
and just use the absolute anchor (version 1.0).

Fine by me. Can you please open an issue to track it?
This makes it easier for me to start voting.

If you would rather use github issues,
that'd be great. There seem to be easy tools
to work with their API, e.g.
http://search.cpan.org/~fayland/Net-GitHub-0.93/lib/Net/GitHub/V3/Issues.pm

We need to come up with a schema to keep the following info in github:
- what is the issue title/short description
- which version fixes the issue?
- what is the proposed spec change?

and then send a script that can get an issue # and
print that, similar to virtio-jira.pl in virtio-admin.

Help with that is very welcome but if you'd rather not you
can just use jira for now.
Pls remember to set fixed in to 1.1 and environment to
reporter name and email (yourself).

I'd vote (heh) to just use jira for now. Especially as I'd like to get
the big batch of the packed ring updates out of the way before we start
to tweak our tooling...

I had a look at the script mentioned above and the GitHub API. I'm not
too eager to do this GitHub issues support at the moment, so I'm going
to stick with Jira.
