[Bug 2095074] Re: [SRU] Upgrade to media driver version 24.3.4 in Noble

[Dave Jones]

Looking at this during my patch pilot shift.

I'm probably not the best person to review this -- I suspect someone on
the desktop team would be better, but from a quick look at the
associated PPA, and the current status of the packages in question,
would I be right in thinking this is basically bumping noble to the
oracular versions of the affected packages? I haven't checked if the
versions are entirely equivalent -- this is based purely on the version
numbers involved.

The patches are sufficiently large that it's probably impossible to
review on that basis, but if it can be verified that these equivalent to
the oracular versions then that's probably sufficient. The question then
becomes whether there are other dependencies potentially affected, but
that's where I'd like to see the input of someone more familiar with the
media stack.

Bug description:
  [ Description ]
  Intel has requested us to update the media driver (free and non-free) to 24.3.4 due to the need to have Lunar Lake (LNL) and Battle Mage (BMG) support.

  This request has a strong dependency on an intel-gmmlib version bump
  to 22.5.2 and a libva version bump to 2.22.0.

  [ Impact ]

   * Users with Lunar Lake or Battlemage currently do not have an LTS support option, which is not a good option for some users, as seen here:
  https://github.com/canonical/intel-graphics-preview/issues/8

   * Users with Lunar Lake or Battlemage hardware will not have
  hardware-enabled media support, which can effect the power consumption
  and CPU utilization of the machine during encode/decode/transcode
  operations, video calls, streaming, etc.

  [ Test Plan ]

  # On a Lunar Lake or Battlemage machine

  # Required at this time to get baseline enablement
  sudo add-apt-repository ppa:kobuk-team/intel-graphics-testing
  sudo apt update

  # Get the original versions back
  sudo apt install -y intel-media-va-driver-non-free=24.1.0+ds1-1  libva2=2.20.0-2build1 libigdgmm12=22.3.17+ds1-1  vainfo=2.12.0+ds1-1 libva-drm2=2.20.0-2build1 libva-wayland2=2.20.0-2build1 libva-x11-2=2.20.0-2build1

  # This should result in an error
  sudo vainfo

  sudo add-apt-repository -y ppa:mckeesh/testing && sudo apt -y update
  # Only upgrade the media packages
  sudo apt install -y intel-media-va-driver-non-free=24.3.4+ds1-0ubuntu1  libva2=2.22.0-1ubuntu1 libigdgmm12=22.5.2-0ubuntu1 libva-drm2=2.22.0-1ubuntu1 libva-wayland2=2.22.0-1ubuntu1 libva-x11-2=2.22.0-1ubuntu1 vainfo=2.12.0+ds1-1

  # This should no longer result in an error
  sudo vainfo

  [ Where problems could occur ]

   * This is a sizable change, and while significant testing goes into
  making sure the media stack does not regress, it's always a risk.
  Ubuntu has a large user base with many, many corner cases, and media
  stack bumps can always accidentally regress a less popular codec on an
  older platform. However, we can address any smaller regressions that
  might arise when the benefit is enablement of LNL and BMG.

  * Beyond Intel's extensive in-house testing, we have done our own
  testing via FFMPEG to check for AV1, VP9, and H264 hardware
  acceleration for encode and decode at 1080p and 4K. In addition to
  Lunar Lake and Battlemage, we have also tested Alder Lake, Comet Lake,
  and Gemini Lake and found no regressions across these platforms
