** Description changed:
[Impact]
The graphics HWE stack from questing needs to be backported for 24.04.4
builds available on
https://launchpad.net/~canonical-x/+archive/ubuntu/x-staging/+packages
rust-annotate-snippets-0.11
- bumped runtime dep of rust-bindgen-0.71
- forked as a new versioned source package
rust-proc-macro2-1.0
- bumped build-dep of rust-bindgen-0.71
- forked as a new versioned source package
meson-1.7
rust-bindgen-0.71
rust-bindgen-cli-0.71
- bumped build-deps of mesa
- forked as a new versioned source package
rust-no-panic-0.1
- bumped build-dep of mesa
- forked as a new versioned source package
rust-rustc-hash-2
- new build-dep of nvk driver
- new source in noble
libdrm
- bumped build-dep of mesa
wayland-protocols
- bumped build-dep of mesa
- this is a full backport, but with tests disabled so that we don't need
to backport a newer wayland as well (due to the need for wayland-scanner)
mesa-compat
- a new source package based on 25.1.7 plus a revert bringing osmesa back
- builds libxatracker and libosmesa which got removed from main mesa
mesa
- new major release, last of the series (25.2.x) so it has accumulated all
the fixes upstream considered worthy for it
- new HW support, bugfixes
+ xwayland
+ - mesa dropped support for (deprecated) wl_drm, so make it optional in
xwayland
+ and use linux-dmabuf instead
+
[Test case]
For the rusty build-depends, the only test needed is to see that they
build, and they allow mesa to build.
For mesa, 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.
Also test WebGL on a browser like Firefox/Chromium
- open https://webglsamples.org and run some demos
Note that upstream releases have already been tested for OpenGL and
Vulkan conformance by their CI.
+ For xwayland the test case is running 'glxinfo -B' after installing it
+ with the mesa update, it should list the native driver instead of
+ llvmpipe.
+
[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.
