Thanks, a new version with the explanation added to d/changelog is now
uploaded.
I'll move migration to llvm-20 to bug 2111265, it will be handled
separately.

[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-20
- - 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
+ spirv-headers
+ - backport from plucky
+ - build-dep of new spirv-tools
spirv-tools
- backport from plucky
- has a bugfix that the intel shader compiler needs
+ - NOTE! the current version in noble FTBFS due to some toolchain issue, but
this version builds, hence the full backport instead of just patching the
current one
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
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
+ - new HW support, bugfixes
[Test case]
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.
