[Bug 1716203] Re: Backport packages for 16.04.4 HWE stack

[Pranav Sharma]

Sorry about this silly question, but will this update be shipped in
February? If it isn't tied to the HWE release schedule and can be
released earlier, is there any way I can help test?

Bug description:
  [Impact]

  *** hwe-16.04 refresh for 16.04.4 ***

  A minor update, only some driver updates plus a newer Mesa.

  Mesa needs llvm-toolchain-5.0 and libclc, libdrm, wayland-protocols
  updates.

  [Test case]

  upgrade from/to stock & old hwe stack, test desktop usage

  [Regression potential]

  libdrm:
  Slim to none, changes from 2.4.76 to 2.4.83
  - amdgpu: pci-id handling moved here, new pci-ids, bugfixes, tests
  - intel: new pci-ids
  - drm: leak fixes, manpage updates
  - exynos, etnaviv, freedreno, android: fixes, new stuff

  wayland-protocols:
  None, just adds a few protocol definitions (xml files)

  llvm-toolchain-5.0:
  None, a new package

  libclc:
  I'd say none, very little has changed, added support for llvm-5 is the main reason for this slightly newer snapshot

  xorg-server:
  Slim, it's an upstream bugfix release, changes from 1.19.3 to 1.19.5 include:
  - security fixes
  - backported bugfixes to glamor, modesetting driver, xwayland etc

  mesa:
  New major release plus a few bugfix updates after that. Regressions at this point are less likely. Upstream is tested by Intel CI system for instance. And we're already testing it via a ppa on OEM systems for 16.04.4. Tracking bug for the bugfix release (xenial & artful) is bug 1727390

  [Other information]

  build order: [libdrm, wayland-protocols, llvm-toolchain-5.0], [libclc,
  xorg-server], mesa
