Backport packages for 22.04.3 HWE stack

[Timo Aaltonen]

[Impact]
The graphics HWE stack from lunar needs to be backported to jammy for 22.04.3

mesa
- new major release (23.0.4)

mesa-amber
- a minor update from upstream mesa (21.3.7 -> 21.3.9), though there were no
  changes to the classic dri drivers
- drops old i915 driver, while mesa provides the more modern i915_dri.so called
  i915g
- fixes installation (LP: #2006744) and image build

[Test case]
mesa:
Install the new mesa on various hw configs, check that everything still works like before or better.

mesa-amber:
no need to test anything besides checking that the packages can be installed next to mesa and image build is fixed

[Where things could go wrong]
This is a major update of Mesa, there could be regressions but we'll backport the final stable release of 23.0.x in order to minimize the chance for those.

Hello Timo, or anyone else affected,

Accepted mesa into jammy-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/mesa/23.0.4-0ubuntu1~22.04.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-jammy to verification-done-jammy. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-jammy. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

After testing packages from the proposed repository for the pending 22.04.3 point release I noticed that color management profiles are no longer being applied in an Xorg session. I suspect this may be related to the mesa packages as I noticed the breakage when rebooting shortly after updating to the 23.0.4 version, though it's possible that there were other proposed packages installed at the same time. Re-applying the icc profile or e.g. switching to the red/green 'inverted' test icc profile no longer have any effect after the update.

[Harm van Bakel (hvbakel)]

Actually, looks like I was wrong. After reverting the proposed repository, reinstalling only the new mesa and mesa-amber packages, and rebooting, color management is working properly. The breakage must have been due to another package update.

[Ubuntu SRU Bot (ubuntu-sru-bot)]

All autopkgtests for the newly accepted mesa (23.0.4-0ubuntu1~22.04.1) for jammy have finished running.
The following regressions have been reported in tests triggered by the package:

gtk4/blacklisted (s390x)

Please visit the excuses page listed below and investigate the failures, proceeding afterwards as per the StableReleaseUpdates policy regarding autopkgtest regressions [1].

Thank you!

[Timo Aaltonen (tjaalton)]

autopkgtests have cleared, and testing completed via 2021948

[Harm van Bakel (hvbakel)]

After some more testing it looks like color management in an Xorg session may be broken when using mesa 23.0.4 in combination with the 6.2 kernel on 22.04 LTS. On two different systems I've noticed that color management works when using kernel 6.2 with mesa 22.2.5, as does the combination of kernel 5.15.0 or 5.19.0 with mesa 23.0.4. However, when I use kernel 6.2 in combination with mesa 23.0.4, color management on an Xorg session is broken. See also https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2023910 for more information on a similar issue reported using kernel 6.2 on 23.04.

[Timo Aaltonen (tjaalton)]

I wouldn't call that "broken" but different, and looks like it only affects (some?) AMD GPU's.

[Andreas Hasenack (ahasenack)]

What's the conclusion here? Should we stop this update until we understand better why the color management changed?

[Łukasz Zemczak (sil2100)]

We discussed this with Timo, and since this update is required for HWE of 22.04.3 and the issue is not considered a blocker, I would like to proceed with releasing this before we build our first image candidates.

[Łukasz Zemczak (sil2100)]

The verification of the Stable Release Update for mesa has completed successfully and the package is now being released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.
