Public bug reported:
[Impact]
The graphics HWE stack from noble needs to be backported for 22.04.5
directx-headers
- build-dep of the new Mesa
mesa
- new major release (24.0.9)
- new HW support, Meteor Lake..
[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 noble, we'd already know
if there are serious issues.
