FFe for updating -intel to 2.9.0

[Bryce Harrington]

Binary package hint: xserver-xorg-video-intel

[Request]
Update of xserver-xorg-video-intel to version 2.9.0.

[Rationale]
2.9.0 is almost entirely a bugfix-only release. It contains one new feature, which is the addition of support for a new chipset. No existing functionality is removed. There are no changes in ABI/API. There are no changes in dependency versions.

At UDS we knew the schedule for 2.9.0 placed it at around beta, and so set our requirements to 2.8.x, with a "maybe" for 2.9.0 if it was entirely bug-fix and was especially stable. In our evaluation, it does meet the criteria we required of it. It is proving to be quite stable, and aside from the one chipset feature (which we need in order to support customers) is entirely bug fixes. In fact it includes fixes for a number of bugs we have forwarded to them over the past few months, including solving some longstanding i8xx regressions that have plagued us for several releases.

[Testing]
In addition to going through Intel's QA testing procedures, we have carried git snapshots of the 2.9.0 driver and the release candidates leading up to it in our xorg-edgers repository. A number of people run this repository routinely, and report bugs to launchpad so we have had good visibility into the quality of this particular release.

Additionally, the specific package version we propose to incorporate is derived from Debian's xserver-xorg-video-intel (2:2.9.0-1), which is being tested in unstable presently.

[Contingency]
If this FFe is accepted, we will also place the current 2.8.x driver into the x-retro PPA at the same time, versioned in a way that enables reversion to the older driver. If by chance there are any serious regressions found in the 2.9.0 driver, we will be able to revert back to the prior 2.8.x driver with minimal effort.

If this FFe is not accepted, we can cherrypick individual patches from the release (indeed, we've already been doing this), although we probably will not have time to backport all the fixes we would like to see in karmic.

Here is the changelog and release notes:

Release 2.9.0 (2009-09-28)
==========================
We are pleased to announce the 2.9.0 release of the xf86-video-intel
driver. (If you have been following along at home, this release is
identical to the 2.8.99.902 release candidate other than the version
number).

New features in 2.9 compared to 2.8
===================================
* Support for the B43 chipset.

Major fixes in 2.9.0 compared to 2.8.0
======================================
* Multiple fixes to make the driver stable for 8xx chipsets, (855GM,
  865G, etc.). The 2.8 driver series was extremely unstable with many
  of these chipsets.

  https://bugs.freedesktop.org/show_bug.cgi?id=22904 (and many duplicates)
  https://bugs.freedesktop.org/show_bug.cgi?id=22947

* Add support for BACKLIGHT property when using kernel modesetting
  (KMS). This allows backlight adjustment with programs such as
  "xbacklight -set <percentage>" or "xrandr --set BACKLIGHT <value>".

  https://bugs.freedesktop.org/show_bug.cgi?id=20963

* Fix so that "xrandr --scale" works when using KMS.

  https://bugs.freedesktop.org/show_bug.cgi?id=22893

* Fix segfaults of X server when logging out.

  https://bugs.freedesktop.org/show_bug.cgi?id=20516

* Avoid falling back to software for 1-bit alpha-only masks.

  https://bugs.freedesktop.org/show_bug.cgi?id=23184

* Fix pixel sampling position for 8xx chipsets, (fixes some cairo-test
  suite failures).

All changes from 2.8.0 to 2.9.0
===============================

      Increment version to 2.8.99.902
      NEWS: Add notes for the 2.9.0 release.
      Increment version to 2.9.0

Chris Wilson (10):
      i830: do not use stale mask transform
      i830: remove padding NOOPs from composite
      i830: Trim composite setup
      i830: Update comments
      i830/i915: Set the sample position to the pixel center.
      i915: Restore nearest sampling
      Avoid fallbacks for compositing gradient patterns
      Avoid fallbacks for a1 src/mask
      Check the correct Picture for error during creation.
      Revert "8xx: Fallback for any non-affine transformation."

Dave Airlie (5):
      intel: remove unneeded includes
      intel: update for resources/RAC API removal
      intel: since driver depends on newer server don't ...

Ack'ed, this is part of intel Q3-2009 bugfix release (with kernel 2.6.31.2, libdrm 2.4.14, mesa 7.6), and it makes sense to have the whole stack in 9.10. Possible bugreports are easier to forward upstream when the baseline is well known to them.

[Bryce Harrington (bryce)]

I went ahead and uploaded this after getting a thumbs up from pitti, but I'd still like to see an official approval from the release team for this one, just for the sake of formality...

[Martin Pitt (pitti)]

As discussed on IRC, the changes are bug fixes and aren't too many of them either, and QA on intel's side looked very thorough. The package was tested in x-updates PPA before as well. The only new feature was support for b43 which we planned anyway.

Approved.
