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

[Chris Halse Rogers]

Right, but as far as the archive is concerned, libdrm-tegra0 itself is
unused :)

What code *does* use libdrm-tegra0, and how sure are we that it doesn't
use those symbols (even accidentally)?

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.
