** Description changed:

  [Impact]
  The graphics HWE stack from plucky needs to be backported for 24.04.3
  
  directx-headers
  - bumped build-dep of mesa
  
  spirv-llvm-translator
  - build-dep of llvm
  - note that some symbols changed/added/dropped on certain archs due to older
    gcc/toolchain, so dh_makeshlibs was overridden to not care about those
  
  llvm-toolchain-20
  - new source in noble
  - build-dep of mesa
  - required for new AMD platforms
  - needs two uploads:
    * 1st stage bootstrap build
    * 2nd stage after spirv-llvm-translator has built against 1st stage
  
- mesa
- - new major release, last of the series (25.0.7) so it has accumulated all
-   the fixes upstream considered worthy for it
- - new HW support, FIXME
+ spirv-tools
+ - backport from plucky
+ - has a bugfix that the intel shader compiler needs
  
  wayland-protocols
  - bumped build-dep of mesa
  - note: this is NOT the version from plucky, which would require a newer wayland
    as well, but instead the oldest update to make mesa happy

  We want to cover at least 2-3 different, widely used and already previously supported GPU generations from both AMD and Intel which are supported by this release, as those are the ones that cover most bases; nouveau users tend to switch to the NVIDIA driver after installation. No need to test ancient GPU's supported by mesa-amber. And best to focus on the newer generations (~5y and newer) as the older ones are less likely to break at this point.
  - AMD: Vega, Navi1x (RX5000*), Navi2x (RX6000*), Navi3x (RX7000*)
  - Intel: gen9 (SKL/APL/KBL/CFL/WHL/CML), gen11 (ICL), gen12 (TGL/ADL/RKL/RPL/DG2)
  
  Install the new packages and run some tests:
  - check that the desktop is still using hw acceleration and hasn't fallen back to swrast/llvmpipe
  - run freely available benchmarks that torture the GPU (Unigine Heaven/Valley/Superposition)
  - run some games from Steam if possible
  
  and in each case check that there is no gfx corruption happening or
  worse.
  
  Note that upstream releases have already been tested for OpenGL and
  Vulkan conformance by their CI.
  
  [Where things could go wrong]
  This is a major update of Mesa, there could be regressions but we'll try to catch any with testing. And since it shares bugs with plucky, we'd already know if there are serious issues.
