Just a quick note on the "linked issue (if applicable)" checklist item: I think it should always be applicable, given that the contributing guide requires us to create an issue if one does not exist. Though it is functionally an honesty/due diligence check for your first checklist item, so you may prefer to keep it as is :) |

Thank you for moving this across. As well as https://code.launchpad.net/~mckeesh/sru-docs/+git/sru-docs/+merge/491986 that you linked there's also https://lists.ubuntu.com/archives/ubuntu-release/2025-February/006315.html and discussion over subsequent months, and https://wiki.ubuntu.com/IntelGraphicsUpdates. All should be checked for anything outstanding before landing this. |

Aargh, sorry I didn't catch this before - libva is used by AMD video acceleration, as well, and any regression there is not likely to be caught by Intel internal testing (I presume?).
libva looks mostly un-scary, but we should probably at least do a smoke test; even something as simple as running vainfo on a couple of AMD GPUs.

Yes, good point. Libva is quite reliable, but testing the integration makes sense. I've gone a step further and found that our ffmpeg testing works on an AMD machine, so we should run that.
Gstreamer testing currently appears to be Intel specific, but the goal of this testing is to be more broadly applicable (especially as I start merging media testing to checkbox). Since the testing relies heavily on libva tracing, I suspect AMD support will be a small gap to fill in over time.

Description
Previous review here:

This PR proposes a process for allowing full-stack upgrades for Intel GPU enablement in LTS releases. This is needed because aside from Mesa and the kernel, our LTS releases do not have support for new Intel hardware. This leaves important cases such as compute, media, and raytracing completely broken for products released over a year ago in Noble.
