[Bug 1991761] Re: Backport packages for 22.04.2 HWE stack

[Łukasz Zemczak]

Hello Timo, or anyone else affected,

Accepted llvm-toolchain-15 into jammy-proposed. The package will build
now and be available at https://launchpad.net/ubuntu/+source/llvm-
toolchain-15/1:15.0.6-3~ubuntu0.22.04.2 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.

Bug description:
  [Impact
  The graphics HWE stack from kinetic needs to be backported for 22.04.2

  directx-headers
  - build-dep of the new Mesa

  libdrm
  - build-dep of the new Mesa

  llvm-15
  - new package in jammy
  - build-dep of the new Mesa

  mesa
  - new major release (22.2.x)
  - new HW support, like AMD RDNA3, Intel DG2

  spirv-headers
  - needed by s-l-t-15

  spirv-llvm-translator-14
  - needed to bootstrap libclc from llvm

  spirv-llvm-translator-15
  - needed for the actual libclc-15 after initial bootstrap

  Bootstrapping plan:
  - s-l-t-14 built from NEW
  - llvm-15 built with s-l-t-14
  - s-l-t-15 built against llvm-15
  - llvm-15 built again with s-l-t-15
  -> mesa ready for building

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

  spirv-headers:
  - test reverse-build-deps that they still build
  Reverse-Build-Depends
  * glslang
  * intel-graphics-compiler
  * spirv-llvm-translator-14
  * spirv-llvm-translator-15
  * spirv-tools
  * vkbasalt
  * vkd3d
  * vulkan-validationlayers

  [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 22.2.x in order to minimize the chance for those.
