The -ati box has turned out to be DOA due to a bad motherboard, so I've
been unsuccessful getting tests on that.

However, I've posted the nouveau and intel tests here:

  http://people.canonical.com/~bryce/mesa804-piglit/

Note this set of runs uses a newer piglit checkout than my previous runs
against mesa 8.0.3.

The Intel results look good, with a number of passed tests increasing by
+10 from 6463/6618 to 6473/6618.  However, note that there are four
tests which regress (see at
http://people.canonical.com/~bryce/mesa804-piglit/intel/regressions.html).
I'm not certain what to make of that, it's not clear why they failed.
Maybe these are unimportant, but I'll follow up on them.

The nouveau results look even better, at +705 passing from 478 to 1183,
however note that the low initial number is due to one of the earlier
tests triggering a kernel oops (bug #1047710); with the newer mesa, that
bug doesn't get tripped but a later test trips a GPU lockup (bug
#1050035).  So we can say that mesa 8.0.4 improves things significantly,
but bugs remain.


** Description changed:

  [Impact]
  Fixes graphics corruption, application crashes, and xserver crashes across a 
wide array of hardware.  Several of these issues  have been reported against 
mesa.  Others are likely affecting users but they don't realize it's mesa at 
fault so we haven't seen their bug reports.
  
  The release notes for 8.0.3 (http://www.mesa3d.org/relnotes-8.0.3.html)
  indicates it contains over 20 bug fixes.  Some of those are fixes to
  make tests pass or fix build issues and may or may not be actually
  relevant to end users.  At least two bugs (#952896 and #988343) reported
  in Launchpad.  Others fix corruption issues and xserver crashes seen
  while running games, memory leaks, and swrast problems.
  
  Of particular note, this includes fixes for GPU hangs in 3D
  functionality.  We've had numerous reports of Intel hangs that are
  difficult for users to reliably reproduce, and it's my hope these fixes
  will help alleviate some of those hangs.
  
  8.0.4 fixes 8 more bugs on top of that (http://upstream-
  tracker.org/changelogs/mesa/8.0.4/changelog.html).
  
  [Fix]
  8.0.3 was uploaded to Quantal prior to Alpha-2.  8.0.4 was also added to 
Quantal and was in the archive for 4 days prior to us moving to the 9.0 branch. 
 This proposal is targeting the 8.0.4-0ubuntu1 package we used in Quantal for 
Precise.
  
  [Test Case]
  See the individually mentioned bugs for test cases of the specific bugs.
  
  For general validation of the point update of mesa, the piglit test
  suite can be used.
  
  1.  Install prerequisites:
       sudo apt-get --yes install cmake g++ mesa-common-dev libgl1-mesa-dev \
          libtiff4-dev zlib1g-dev libpng12-dev python-numpy \
          freeglut3-dev x11proto-gl-dev libxrender-dev
  2.  Checkout the piglit test suite from upstream
       git clone git://anongit.freedesktop.org/git/piglit
       cd piglit; cmake . ; make
  3.  DISPLAY=:0 piglit-run.py tests/all.tests mesa802.results
- 4.  Install mesa 8.0.3
- 5.  DISPLAY=:0 piglit-run.py tests/all.tests mesa803.results
- 6.  piglit-summary-html.py summary/compare mesa802.results mesa803.results
+ 4.  Install mesa 8.0.4
+ 5.  DISPLAY=:0 piglit-run.py tests/all.tests mesa804.results
+ 6.  piglit-summary-html.py summary/compare mesa802.results mesa804.results
  
  The tests take several hours to run.
  
  Note:  Piglit is not a comprehensive test suite and cannot guarantee
  that there are no regressions.  However, it is being actively maintained
  and updated with new tests by the driver maintainers as they add
  features and fix bugs in mesa, so should have decent coverage for
  recently made code changes (which is where regressions are more likely
  to live).
  
  [Regression Potential]
  A/B testing was done on the three major open source drivers.  This testing 
found that the new version did not cause regressions, and actually a number of 
tests passed that had failed or been skipped in 8.0.2.  Results are posted at:
  
-   TBD
+   http://people.canonical.com/~bryce/mesa804-piglit/
  
  mesa provides 3D acceleration functionality for all of the open source
  video drivers.  Thus, the types of regressions to watch for with this
  change are:
  
    * X.org crashes, freezes, or errors
    * Graphical corruption when using compositing desktops
    * Crashes, graphical corruption or other failures in 3D applications and 
screensavers
    * Performance regressions in 3D functionality, measured by dropped FPS 
rates in unity or 3D games
  
  For such bugs, the diagnostic process would be to downgrade mesa back to
  8.0.2 (without any other system changes), log out and back in, and
  verify the problem as not reproducible.
