radv is broken for nearly all commercial games in 17.3.4. The cause is

ac/nir: Use instance_rate_inputs per attribute, not per variable.
This did the wrong thing if we had e.g. an array for which only some
of the attributes use the instance index. Tripped up some new CTS

(cherry picked from commit 5a4dc285002e1924dbc8c72d17481a3dbc4c0142)
A typo was introduced during the conflict resolution while
cherrypicking to 17.3.
First things first, can we mitigate this? Would it be possible to get
a 17.3.5 with this fixed ASAP? This can be fixed by either rolling
back ad764e365beb8a119369b97f22225cb95fc7ea8c or by applying
https://patchwork.freedesktop.org/patch/204260/ (obviously not applied
to master as the issue did not occur there).
Secondly, I'd like to talk about process and how to prevent this in
the future. Bugfix releases are supposed to be stable so downstream
maintainers don't have to to deal with this kind of stuff happening,
so I think that breaking radv pretty much completely is particularly
egregious and we should look at how to prevent this happnening another
First a short summary of what happened and when (all times in UTC):
2018-02-09 4:47: Emil sends out the pre-release announcement, git
branch contains the faulty commit
2018-02-13 16:05: James Legg replies to the pre-release announcement:
2018-02-13 16:06: James Legg sends a patch to fix it:
2018-02-13 16:33: Bas reviews the patch.
2018-02-15 12:56: Emil releases 17.3.4 without the fix:
2018-02-16 21:09: Someone else replies with a fix to the pre-release
2018-02-17 ~13:00: Bas notices the attached fix has "mismerge" in the
name and decides to investigate the issue
So I think there have been a couple of issues in communication here:
1) Essentially none of the communication talked about this being an
issue on the branch only. This made me underestimate the severity of
the issue, since the games kept working on master. This also meant no
manual pings from my side to the release manager for not applying this
to master first.
2) The reply to the pre-release announcement only said there was an
issue, not that there was a fix sent out, nor any details like
3) As far as I can tell no action had been taken by the release
manager. James' reply did not get a response nor was the fix included
in the release.
My question would be how to improve the communication here. Could you
elaborate the reason for (3)? Was it because you thought it would have
to be picked up by the radv developers first? Would it help if I
replied to James' reply in the announcement to link to the patch?
The remaining issue is mainly about testing. The initial detection of
this issue by James was already more than the 24-48 hours after the
pre-release announcement that is recommended between the announcement
and release, so a faster release would have prevented timely detection
in the first place. I suspect radv does not get tested at all on
releases except maybe a build test?
Since manually testing all games on every release is not scalable for
either the radv developers or the release manager I'm thinking of
getting the automated tests from the vulkan CTS and crucible running
before a release. That said I don't think keeping track of what tests
are supposed to pass is something we should be pushing on the release
manager, so I suppose we should be setting up our own CI and surfacing
results of the stable branches to the release manager?
I'm assuming there is already a similar arrangement with intel? Is
this something were the release manager triggers their CI specifically
when doing a pre-release or are they just continuously watching stable
branches? Also how do the results get surfaced back to the release
Apologies for the barrage of questions!
