Raw Normal View History

Update to xf86-video-intel 2.20.19. A recent kernel with kernel modesetting support is required. Thanks to jsg@ and kettenis@ for their work.
2013-03-18 12:38:18 -06:00
Release 2.20.19 (2013-01-20)
============================
A quick release as the last broke USB DisplayLink slave outputs badly. The
performance of those displays was unusable due to a inadvertent change that
caused us to flush the entire scanout over the USB for every drawing
operation.
* Implement the GNOME Build API. A couple of minor changes to make
integrators and distributors lives a little easier, or at least more
consistent.
* Correctly offset inplace trapezoids for subwindows, such as the GTK+
close button after it has a background image uploaded.
* Explicitly prevent ring-switching for synchronized rendering to
scanouts (for vsync).
* Clip dirty region to slave pixmaps (otherwise UDL is nigh unusuable)
https://bugs.freedesktop.org/show_bug.cgi?id=59539
Release 2.20.18 (2013-01-16)
============================
A bunch of miscellaneous fixes for assertion failures and various
performance regressions when mixing new methods for offloads, along with
a couple of improvements for rendering with gen4.
* Remove use of packed unnormalized texture coordinates on gen4/5 as
these GPUs do not support unnormalized coordinates in the sampler.
* Remove dependency upon x86 asm for cross-building to unsupported
architectures.
https://bugs.gentoo.org/show_bug.cgi?id=448570
* Apply damage around PRIME updates in the correct order.
* Correctly read the initial backlight level for when the user
overrides UXA's choice of backlight controller.
* Throttle UXA and prevent it queuing work much faster than the GPU can
complete it. This realised itself in impossible performance figures and
the entire display freezing for several seconds whlist the GPU caught
up. One side effect is that it also caused the DDX to consume more
memory than was required as it could not recycle buffers quick
enough, and in some cases this produces a marked improvement in
performance. Also note on gen2/3 this requires a new libdrm [2.4.41]
in order to prevent a bug causing the DDX to fallback to swrast.
Release 2.20.17 (2012-12-26)
============================
A minor update to prepare for co-operating with the kernel over managing
stability on 830gm/845g. On this pair of chipsets, the kernel will perform
an extra copy of the batchbuffer into reserved memory, which prevents them
from randomly dying. However, that extra copy does have a noticeable
impact upon throughput, so we also have a mechanism for userspace to
opt-out of the kernel workaround and take responsibility for ensuring its
batches are coherent.
* Build fixes against xorg-1.14
https://bugs.freedesktop.org/show_bug.cgi?id=58552
https://bugs.freedesktop.org/show_bug.cgi?id=58406
* Fixed the origin of cropped (textured) video windows (Xv and XvMC)
https://bugs.freedesktop.org/show_bug.cgi?id=23033
* Fix potential corruption when using images larger than ~1GiB
Release 2.20.16 (2012-12-15)
============================
Rejoice! We have found a trick to make 830gm/845g stable at long last.
Ever since the switch to GEM and dynamic video memory, those early
second generation chipsets have been plagued by instability. The lack of
flushing cachelines from the CPU to GMCH was eventually solved by using
an undocmented bit, but 830/845 were still hanging under memory pressure.
These deaths were all due to garbage finding its way into the command
streamer, and they go away if we take a leaf out of the original driver
and never reuse those pages for anything else. So for the first time
ever, I have been able to complete running the test suite on an 845g,
even whilst thrashing the page and buffer caches!
* Run the SF stage as single-threaded on gen4 to workaround a few issues
https://bugs.freedesktop.org/show_bug.cgi?id=57410
* Keep the scanout SURFACE_STATE separate to avoid overriding its
memory access control on gen6/7 (i.e. writes to the scanout need to
be kept out of the render cache)
* Tune batch flushing after an operation to an exported surface under a
compositor.
* Make sure the source is on the CPU for inplace composition of trapezoids
using the CPU
https://bugs.freedesktop.org/show_bug.cgi?id=56825
* Immediately flush in the block hander after a split batch to reduce
latency between the two halves of an operation.
https://bugs.freedesktop.org/show_bug.cgi?id=51718
* Install a fallback config if we fail to install the desired config
at VT switch (i.e. booting, after resume with 3 incompatible pipes on
Ivybridge)
* Pin batches to avoid CS incoherence on 830/845
https://bugs.freedesktop.org/show_bug.cgi?id=26345
Release 2.20.15 (2012-12-03)
============================
And lo, enabling more of the common acceleration paths for gen4 revealed
another lurking bug - something is wrong with how we prepare Y-tiling
surfaces for rendering. For the time being, we can surreptiously disable
them for gen4 and avoid hitting GPU hangs.
* Avoid clobbering the render state after failing to convert the
operation to use the blitter.
https://bugs.freedesktop.org/show_bug.cgi?id=57601
* Disable shadow tracking upon server regeneration, and so fix a crash
if you restart the server whilst a RandR transform (e.g. rotation) is
in effect.
https://bugs.freedesktop.org/show_bug.cgi?id=52255
https://bugs.freedesktop.org/show_bug.cgi?id=56608
Release 2.20.14 (2012-11-26)
============================
The highlight of this release is gen4, from 965g to gm45. Quite an old
bug surfaced in the shader assembly, sparking a chance to review a few
design choices within that backend and experiment on fresh ways to
workaround the remaining issues.
* Avoid using inplace XOR'ed uploads for very large buffers
https://bugs.freedesktop.org/show_bug.cgi?id=57031
* Fix the gen4/5 opacity shader
https://bugs.freedesktop.org/show_bug.cgi?id=57054
* Queue a pending vblank request after flip completion
https://bugs.freedesktop.org/show_bug.cgi?id=56423
* Avoid migrating an uninitialised pixmap for use as a render source
https://bugs.freedesktop.org/show_bug.cgi?id=47597
* Improve handing of texture fallbacks for 830/845.
https://bugs.freedesktop.org/show_bug.cgi?id=57392
Release 2.20.13 (2012-11-11)
============================
Nothing but bug fixes. Many thanks to everyone who took the time to
report their issues, and for their help in improving the driver.
* Sanity check the platform probe points to our expected i915 device
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1069031
* Prevent 16-bit overflow for computing the sample area to upload of
sources for render operations
https://bugs.freedesktop.org/show_bug.cgi?id=56324
* Clamp the drawable box for migration to prevent 16-bit overflow
https://bugs.freedesktop.org/show_bug.cgi?id=56591
* Disable RandR hotplug events if Xinerama is enabled and thereby prevent
a crash upon hotplug
https://bugs.freedesktop.org/show_bug.cgi?id=55260
* Call ValidatePicture before attempting to flatten the alphamaps
https://bugs.freedesktop.org/show_bug.cgi?id=56367
* Clip the trapezoid correctly if it ends on the boundary pixel
https://bugs.freedesktop.org/show_bug.cgi?id=56395
* Make sure the pipeline choice is propagated to the scanline wait
across a batch flush
https://bugs.freedesktop.org/show_bug.cgi?id=47597
* Set the valid drawable box when choosing placement of BLT composite ops
https://bugs.freedesktop.org/show_bug.cgi?id=47597
* Prevent use-after-free when promoting a partial-GPU bo to a full-GPU bo
https://bugs.freedesktop.org/show_bug.cgi?id=56591
* gen4 opacity spans require the per-rectangle workaround
https://bugs.freedesktop.org/show_bug.cgi?id=55500
* Prevent use of invalid damage pointers when redirecting rendering
https://bugs.freedesktop.org/show_bug.cgi?id=56785
Release 2.20.12 (2012-10-20)
============================
More bug reports, more bug fixes! Perhaps the headline feature is
that with a secure batches, coming to a 3.8 kernel near you, we may
finally have the ability to perform updates to the scanout synchronized
to the refresh rate on later SandyBridge and IvyBridge chipsets. It comes
at quite a power cost as we need to keep the GPU out of its power saving
modes, but it should allow legacy vsync to function at last. But this
should allow us to address a longstanding issue with tearing on
SandyBridge+.
* Fix component-alpha rendering on IvyBridge, for example subpixel
antialiased glyphs.
https://bugs.freedesktop.org/show_bug.cgi?id=56037
* Flush before some "pipelined" state changes on gen4. The evidence is
that the same flushes as required on gen5+ are also required for gen4.
https://bugs.freedesktop.org/show_bug.cgi?id=55627
* Prevent a potential crash when forcing a stall on a busy CPU bo
https://bugs.freedesktop.org/show_bug.cgi?id=56180
[Release 2.20.11 contained a typo causing UXA to fail immediately.]
Release 2.20.10 (2012-10-14)
============================
The last couple of weeks have been fairly retrospective, a dive into
prehistory tidying up the earlier generations which lay languishing as
the core progressed and lead to a number of annoying core bugs being
fixed.
* Release DRM master earlier during shutdown so switching between
multiple X servers works automatically.
https://bugs.freedesktop.org/show_bug.cgi?id=55446
* Suppress error propagation from DRI2GetMSC and behave as if the pipe
was simply off to avoid unexpected errors in the clients
https://bugs.freedesktop.org/show_bug.cgi?id=55395
* A few fixes to i8xx batch emission, ensuring that the GPU is always
in a valid state.
https://bugs.freedesktop.org/show_bug.cgi?id=55455
* Prevent a use-after-free during UXA shutdown due to inspecting
the glamor flags after the glamor interface had been freed.
* Prevent a crash combining TearFree and rotations.
https://bugs.freedesktop.org/show_bug.cgi?id=55527
* Correct a missing damage upload along PutImage after using the CPU bo
as a source for the GPU.
https://bugs.freedesktop.org/show_bug.cgi?id=55508
* Fix compilation for older glibc without O_CLOEXEC
https://bugs.freedesktop.org/show_bug.cgi?id=55577
* Fix out-of-tree builds failing to recompile the gen4 assemblies
https://bugs.freedesktop.org/show_bug.cgi?id=55645
* Fix non-standard build host configuration handling for intel-gen4asm
https://bugs.freedesktop.org/show_bug.cgi?id=55646
* Fix a potential batch buffer overflow when replacing the last BLT fill
operation with a copy
https://bugs.freedesktop.org/show_bug.cgi?id=55700
* Flush the render pipeline more frequently on Ironlake as not all
pipelined state changes are.
https://bugs.freedesktop.org/show_bug.cgi?id=51422
* Detect when we need to read the destination for the background raster
op during fallbacks.
https://bugs.freedesktop.org/show_bug.cgi?id=55810
* Avoid a potential deference of an invalid CPU mmap after doing an
inplace tiled upload.
https://bugs.freedesktop.org/show_bug.cgi?id=55812
* Prevent sign extension when packing the upload data for CopyPlane
https://bugs.freedesktop.org/show_bug.cgi?id=55823
* Fix some render corruption with a UDL slave output and pageflipping
Release 2.20.9 (2012-09-29)
===========================
And so it came to pass that a critical bug was uncovered in UXA. The
kernel does not like to pageflip when the pipe is off, yet due to the
delayed nature of a pageflip and the relaxed checking performed by UXA,
we could request a pageflip after turning off the display (DPMS). The
kernel rejected that pageflip and the error handling path failed to
restore sanity, and when the screen came back it was stuck on the image
seen before it went to sleep. (Note that there are also some related
kernel bugs, but this update should prevent the most conspicious of the
freezes.) Many thanks to Timo Aaltonen for his efforts in tracking down
the issue.
In other news:
* Prepare for xorg-1.14, the api is being tweaked again.
* Handle early FreeScreen in UXA.
https://bugs.freedesktop.org/show_bug.cgi?id=55346
* Reenable XvMC support
* Do not replace the GPU bo when uploading into the shadow/CPU copy
https://bugs.freedesktop.org/show_bug.cgi?id=54978
* Fix use of an uninitialised GC when drawing glyphs to a depth=1 pixmap
Release 2.20.8 (2012-09-16)
===========================
Another new small feature, another new release. And a few more bugs
fixed as well! But what is this new feature, do I hear you ask? Why, it
is nothing less than enabling the ValleyView SDV! The lucky person to
have their hands on one will now be able to enjoy X in full TechniColor.
For the rest of us, a few more bugs were fixed with interesting
combinations of software and rendering patterns.
* Add an extra layer of defence against trying to use a non-GEM device
with UXA. This should already be taken care of with the new probe,
but the extra sanity check already existed in the code but was doing
nothing.
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/962892
* Fix computation of valid CRTCs bitmask for ZaphodHead
Some systems can only handle certain outputs on certain pipes
(Screens), and this information was not being propagated through to X
and randr correctly, breaking valid configurations and not detecting
invalid configurations correctly.
* Disable global glyph caching with ZaphodHeads.
The glyph privates need to be Screen private, but at the moment are
global leading to conflicts and invalid rendering with multiple heads.
https://bugs.freedesktop.org/show_bug.cgi?id=54707
* Prevent direct read back of unmappable buffers
https://bugs.freedesktop.org/show_bug.cgi?id=54808
* Tile large uploads whilst replacing the alpha channel
https://bugs.freedesktop.org/show_bug.cgi?id=54808
* Correct the source offset when converting a RENDER composite
operation into a BLT composite operation.
https://bugs.freedesktop.org/show_bug.cgi?id=54868
* Correct a minor typo in flattening alphamaps which caused the
replacement pixmap to often end up with a height of zero.
https://bugs.gentoo.org/show_bug.cgi?id=434860
* Don't discard the CPU damage if only part of is being replaced.
This is most evident when combining software renders like Opera with
accelerated rendering.
https://bugs.freedesktop.org/show_bug.cgi?id=54937
Release 2.20.7 (2012-09-08)
===========================
Continuing the flurry of releases, this week saw the release of
xorg-1.13 bringing with it the first steps towards hotpluggable gpu
support and the ability to offload DRI rendering onto other GPUs. In
light of that advance, this release includes the support code by Dave
Airlie to integrate PRIME into xf86-video-intel and make those new
features available.
Aside from landing PRIME, a few other bugs were fixed since 2.20.6:
* Fix framebuffer leak on server regeneration
* Fix texture cache flushing on IvyBridge and Kwin with plastique
https://bugs.freedesktop.org/show_bug.cgi?id=54488
* Redirect large solid fills on SandyBridge+. By large I mean greater
than 8192 or 16384 pixels on SandyBridge and IvyBridge respectively.
https://bugs.freedesktop.org/show_bug.cgi?id=54134
* Fix up backlight option handling in the manpage and uxa.
https://bugs.freedesktop.org/show_bug.cgi?id=54397
* Unbreak ZaphodHeads.
https://bugs.freedesktop.org/show_bug.cgi?id=52438
Release 2.20.6 (2012-09-02)
===========================
A serious bug that caused a crash on SandyBridge and IvyBridge when
mixing CPU and GPU operations on the same buffer, and an annoyance from
bad scheduling of windowed swapbuffer updates causing low framerates and
jitter. Plus the usual smattering of assertion fixes and a long standing
issue with incoherent page access to a streaming buffer.
* Low frame rates in Blobby Valley when "fullscreen"
https://bugs.freedesktop.org/show_bug.cgi?id=54274
* Incoherent concurrent access with the CPU and GPU
https://bugs.freedesktop.org/show_bug.cgi?id=51422
https://bugs.freedesktop.org/show_bug.cgi?id=52299
* Add Option "Backlight" to override automatic selection of the
backlight interface.
* Avoid overwriting the composite operation info when testing if we
can transfer the operation to the BLT.
Release 2.20.5 (2012-08-26)
===========================
Another silly bug found, another small bugfix release. The goal was for
the driver to bind to all Intel devices supported by the kernel.
Unfortunately we were too successful and started claiming Pouslbo,
Medfield and Cedarview devices which are still encumbered by propietary
IP and not supported by this driver.
Bugs fixed since 2.20.4:
* Only bind to Intel devices using the i915 kernel module
* Regression in the bitmap-to-region code, e.g. icewm window buttons
https://bugs.freedesktop.org/show_bug.cgi?id=53699
Release 2.20.4 (2012-08-18)
===========================
Continuing the small bugfix releases, the only real feature is initial
enabling for Haswell for the purpose of rendering verification and
validation - by no means is it complete!
Bugs fixed since 2.20.3:
* Some potential errors along failure paths found by a static analyser
with the help of Zdenek Kablac.
* Eliminate zero-sized rectangles from PolyFillRectangles as the code
assumes that they did not exist and so caused corruption.
* Remove the UXA warning for failing to tile the front buffer if it is
disallowed by hardware, and so expected.
* Fix the validation of the XV pipe parameter.
* Fix 8x8 tiled pattern fills
https://bugs.freedesktop.org/show_bug.cgi?id=53353
* Fix compile failure when using --with-builderstring
* Restore w/a flush for gen4 fill/copy/video, fortunately rare
operations as at least for fill/copy we prefer to use the BLT.
https://bugs.freedesktop.org/show_bug.cgi?id=53119
* Restore preferred use of the RENDER ring for SNB+ DRI copies.
Release 2.20.3 (2012-08-04)
===========================
Just a minor bugfix for gen4 chipsets (965gm, gm45 and friends) that
crept into 2.20.2. As an added bonus, the pessimistic workaround for a
GPU hang on gen4 has been relaxed and the shaders have been overhauled
which should pave the way to eliminating the last of the uncommon CPU
operations, along with immediately realising a small perforamnce
improvement.
Bugs fixed since 2.20.2:
* Update DPMS bookkeeping after modeset
https://bugs.freedesktop.org/show_bug.cgi?id=52142
* Avoid overlapping gpu/cpu damage after ignoring cpu damage in the
consideration of placement for the operation.
* Enable acceleration by default on 830gm/845g. The GMCH on this pair
of chipsets is notoriously incoherent, so the GPU is almost certainly
going to hang at some point, though unlikely to hang the system and
should automatically disable acceleration (and thence behave
identically as if the acceleration was disabled from the start).
Option "NoAccel" can be used to disable all 2D acceleration and
Option "DRI" can be used to disable all 3D acceleration.
https://bugs.freedesktop.org/show_bug.cgi?id=52624
* Fix vertex bookkeeping for gen4 that was causing corruption in the
command stream.
Release 2.20.2 (2012-07-27)
===========================
For the last 9 months, since 2.16.901, we have been shipping a driver that
does not work on IvyBridge GT1 systems (HD2500 graphics); we were telling
the GPU to use an invalid number of threads for the pixel shader and this
in turned caused the GPU to hang.
Also fixed since the last release just a few days ago:
* Support for the gmux backlight controller on Apple laptops
https://bugs.freedesktop.org/show_bug.cgi?id=52423
* Fix X -configure not to list this driver as matching any Intel device,
just the VGA class devices will do!
* A crash in SNA when repeatedly switching xrandr rotations
* Corruption in SNA observed in kwin on IvyBridge
https://bugs.freedesktop.org/show_bug.cgi?id=52473
Release 2.20.1 (2012-07-22)
===========================
A week in, grab the brown paper bags, for it is time to reveal a couple
of critical bugs that spoilt the 2.20.0 release.
Firstly we have the restoration of DRI for i810. I am sure that the
solitary user will be overjoyed in a couple of years when a new xserver
is forced upon him. That enjoyment will be short-lived when as no actual
acceleration remains, not even shadow, for the chipset.
Perhaps a little more wildly felt, I hope!, will be that the SNA
fallbacks were broken on 64-bit machines if they required clipping. One
little misplaced cast of a pointer, and the screen is filled with
corruption.
Among the other tweaks this week:
* A bug affecting gen4 handling of trapezoids was fixed, and CPU
overhead reduced.
https://bugs.freedesktop.org/show_bug.cgi?id=52158
* A fix for a bug causing corruption of a DRI2 unredirected client
window that was resized whilst under a compositor.
* Support for snoopable buffers on non-LLC architectures, coming to
a future kernel. The aim to accelerate transfers between the CPU
and the GPU, in particular to dramatically improve readback
performance, and to further minimise clflushes.
* Improvement to the composite performance on GT2 SandyBridge and
IvyBridge devices, in particular the render copy is significantly
improved.
* Improved handling for when acceleration is disabled, including
permitting DRI2 to remain supported even if the X server believes
the GPU wedged.
* Shadow support was dropped from UXA as it was neither complete nor
correct, use SNA instead.
Release 2.20.0 (2012-07-15)
===========================
First the big news, a new acceleration method that aims to be faster and
consume far less CPU than UXA is now available for selection at runtime.
This snazzy new architecture can be selected through use of
Option "AccelMethod" "sna"
in your xorg.conf. Whilst it has been under development for some time, it
has not yet had the same degree of widespread testing of UXA, so tread
lightly. Try it and if you spot anything that can be improved, please do
report a bug.
Otherwise we have the usual smattering of bug fixes for UXA:
* Use a white source whilst adding glyphs to the glyph mask
(This fixes blank glyphs if using a font that mixes ARGB and A glyphs.)
* Avoid fallbacks for glyph-to-dst in e.g. gnome-terminal
https://bugs.freedesktop.org/show_bug.cgi?id=50508
* Force unused outputs off when VT switching
https://bugs.freedesktop.org/show_bug.cgi?id=50772
* Copy the fbcon across to the Screen pixmap at startup.
(This patch has been kicking around in the distributions for years.)
* Many missed malloc failures checks and forgotten frees found by a static
analyzer. Thanks Zdenek Kabelac!
* Leak of the back buffer when terminating an application after pageflipping
https://bugs.freedesktop.org/show_bug.cgi?id=50670
* Double check that the pipe is on before emitting a WAIT_ON_EVENT.
In conjunction with an uptodate kernel, this should eliminate any
hangs when changing resolutions or adding/removing displays.
https://bugs.freedesktop.org/show_bug.cgi?id=50668
* Update to new Xorg APIs. Future proofing for the next generation of
hotplug Xorg display servers.
Many thanks to everyone who has reported a bug and otherwise helped to
improve the driver.
Release 2.19.0 (2012-04-29)
===========================
More stability fixes for UXA and support for another variant of IvyBridge.
Given the severity of the stability fixes, I strongly recommend everybody
to upgrade to 2.19.0.
* Prevent waiting on scanlines whilst not in control of the VT and therefore
whilst referencing foreign CRTC configurations.
* Pixmap (and bo leak) during fallback glyph composition
* Remove broken acceleration for rendering glyphs directly upon the
destination pixmap, exposed by cairo-1.12.0 (and coincidentally fix
another Pixmap leak upon fallback handling).
* Add support for Ivy Bridge GT2 Server chipset [PCI id 0x016a]
* Remove broken damage flushing with CompositeRectangles
https://bugs.freedesktop.org/show_bug.cgi?id=32547
* Fix crash upon server start with multiple monitors
https://bugs.freedesktop.org/show_bug.cgi?id=47395
* Fix composition issues resulting from overly aggressive Pixmap reuse
https://bugs.freedesktop.org/show_bug.cgi?id=47345
Release 2.18.0 (2012-02-24)
===========================
Time passes, a few more bugs have crept out of the woodwork that are a
compelling reason to update.
Bugs fixed in this release (compared to 2.17.0)
-----------------------------------------------
* Limit maximum object size so that all of the source, mask and
destination can be mapped into the aperture simultaneously by basing the
limit on the mappable aperture size rather than the size of the total
GATT.
* Incorrect clipping of polygons
https://bugs.freedesktop.org/show_bug.cgi?id=43649
Regression from 2.15.901
* Limit number of VMA cached to avoid hitting the per-process VMA limit
There still is a residual bug in that we seem to have so many objects
floating around in the first place and that still leads to exhaustion
of system limits.
https://bugs.freedesktop.org/show_bug.cgi?id=43075
https://bugs.freedesktop.org/show_bug.cgi?id=40066
* Latency in processing user-input during continuous rendering
Release 2.17.0 (2011-11-16)
==============================
A few months have passed, and we have accumulated a surprising number of
bug fixes. Oops! We would strongly encourage everyone to upgrade.
Bugs fixed in this snapshot (compared to 2.16.902)
--------------------------------------------------
* Video clobbering composite batch state
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=635953
Snapshot 2.16.902 (2011-11-13)
==============================
This is the second release candidate in preparation for the upcoming
2.17.0 release. We will appreciate any feedback we can get from
testing of this snapshot, and thanks to everyone who tested and reported
upon issues in the last snapshot.
A very old bug demonstrating that nobody has ever used alpha maps, and a
couple of more recent mistakes were found.
Bugs fixed in this snapshot (compared to 2.16.901)
--------------------------------------------------
* Incorrect reuse of surface bindings within a batch for multiple formats

https://bugs.freedesktop.org/show_bug.cgi?id=31819
* Handle fallbacks involving alpha maps
Snapshot 2.16.901 (2011-10-30)
==============================
This is the first release candidate in preparation for the upcoming
2.17.0 release. We will appreciate any feedback we can get from
testing of this snapshot.
The basis of this release are to push out a couple of critical stability
fixes for SandyBridge and IvyBridge. There is very little else to see
here. Those 200+ other commits do not exist...
Bugs fixed in this snapshot (compared to 2.16.0)

Release 2.16.0 (2011-08-09)
==============================
A new quarter, a new release! The key feature of this release, looking past
the bug fixes, is the enabling of IvyBridge acceleration. We have also fixed
many bugs and graphical glitches and would encourage everyone to upgrade.
Update the intel driver to 2.9.1 plus backports. 2.9.1 is the last version of the intel DDX that supports UMS (User modesetting), with 2.10 onwards being purely KMS only. As such, this driver contains backports of almost every correctness or performance related fix to the rendering layer in later intel drivers. This driver *REQUIRES* a GEM enabled kernel. it claims to support non-gem mode but this is essentially unmaintained and due to the way the abstraciton works is slow, if it works at all (it often does not). You have been warned. tested by many many people on tech over the last few weeks.
2010-05-10 16:32:28 -06:00
Update to xf86-video-intel 2.20.19. A recent kernel with kernel modesetting support is required. Thanks to jsg@ and kettenis@ for their work.

Bugs fixed in this snapshot (compared to 2.15.901)
--------------------------------------------------
* Build fix for xserver-1.7.7
Snapshot 2.15.901 (2011-07-30)
==============================
This is the first release candidate in preparation for the upcoming
2.16.0 release. We will appreciate any feedback we can get from
testing of this snapshot.
The highlight of this snapshot is the full enabling of IvyBridge with
acceleration for Render and Xv, along with handling of the shared render
buffer allocations required for Mesa. Also of note is that deep-color
support is enabled (for all chipsets), which allows you to drive your
30-bit monitor at its native colour depth.
Bugs fixed in this snapshot (compared to 2.15.0)

https://bugs.freedesktop.org/show_bug.cgi?id=36319
Release 2.15.0 (2011-04-14)
==============================
We are pleased to announce this major release of the xf86-video-intel
driver, roughly on schedule at 3 months since 2.14.0. With the many bug
fixes in this release, we encourage everyone to upgrade to 2.15.
The priority for this quarter has been simply to be unexciting and stabilise
the driver further, seeking to capitalise upon the improvements elsewhere
in the stack.
Bugs fixed in this snapshot (compared to 2.14.903)
--------------------------------------------------
* Turn off relaxed fencing by default for older chipsets
This was continuing to destabilize those system, so for the release
we disabled the feature. If you wish to help us debug this, you can
re-enable the optimisation with Option "RelaxedFencing" "True".
Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=36147
* Build fix for xserver-1.7.7
* KDE glitches on SNB
[Technically fixed in the previous snapshot, but I'm really pleased
that this got fixed in time for the release!]
https://bugs.freedesktop.org/show_bug.cgi?id=35808
Snapshot 2.14.903 (2011-04-11)
==============================
This is the third release candidate in preparation for the upcoming
2.15.0 release. We will appreciate any feedback we can get from
testing of this snapshot.
There was a bit of churn since 2.14.902 as a potential fix for a
performance regression was tried but had to reverted when it was found to
cause glitches running Compiz on SandyBridge. Otherwise, there were just a
couple of fixes for building against old xservers and running on an
obscure chipset.
Bugs fixed in this snapshot (compared to 2.14.902)
--------------------------------------------------
* Prevent issuing an invalid scanline wait command
https://bugs.freedesktop.org/show_bug.cgi?id=35576
* The 946GZ in not a 945, but a 965.
https://bugs.freedesktop.org/show_bug.cgi?id=35854
* Fix tile sizes for gen2 (finally).
* Allow building of recent dri2 changes against old xservers.
Snapshot 2.14.902 (2011-03-29)
==============================
This is the second release candidate in preparation for the upcoming
2.15.0 release. We will appreciate any feedback we can get from
testing of this snapshot.
As befits testing of release candidates, no major regression was found and
a couple more bugs have been fixed.
Bugs fixed in this snapshot (compared to 2.14.901)
--------------------------------------------------
* Clients disappearing with pending swaps
* Incorrect clipping of Xv output on i915 across extended desktops
https://bugs.freedesktop.org/show_bug.cgi?id=35346
* Introduction of a LinearFramebuffer option. (Defaults to tiled for
performance and power saving.)
Snapshot 2.14.901 (2011-03-02)
==============================
This is the first release candidate in preparation for the upcoming
2.15.0 release. We will appreciate any feedback we can get from
testing of this snapshot.
Still no further along my grandiose plans to improve Render performance,
aside from the performance tuning lower in the stack, instead we have had
a steady stream of bug fixes.
Bugs fixed in this snapshot (compared to 2.14.0)
------------------------------------------------
* Green pixels within partially off-screen video playback
https://bugs.freedesktop.org/show_bug.cgi?id=24767
* Defer creation of the glyph cache to generation startup
https://bugs.freedesktop.org/show_bug.cgi?id=33412
* Incorrect maximum addresses for video decoder state
https://bugs.freedesktop.org/show_bug.cgi?id=34017
* Failure to handle oversized temporary surfaces
https://bugs.freedesktop.org/show_bug.cgi?id=34399
* Relaxed tiling corruption on gen2
* Crash when destroying a foreign DRI drawable
https://bugs.freedesktop.org/show_bug.cgi?id=34787
Release 2.14.0 (2011-01-07)
===========================
We are pleased to announce this major release of the xf86-video-intel
driver, on schedule at 3 months since 2.13.0. With the many bug fixes
in this release, we encourage everyone to upgrade to 2.14.
The most notable feature of this release is the inclusion of acceleration
support, both RENDER and XVIDEO, for Sandy Bridge; note that this requires
a 2.6.37 kernel. In improving the acceleration code paths to support Sandy
Bridge, we were also able to improve the performance of the general i965+
RENDER acceleration. For example on i3, glyph (aa10 and rgb10) performance
is about 3x faster, as is performing small copies between windows, with the
improvement becoming negligible once you hit around 100 pixels square.
Snapshot 2.13.903 (2010-01-04)
==============================
This is the second release candidate in preparation for the upcoming
2.14.0 release, and if no showstoppers turn up in wider testing will
become the next release. Besides the usual bug fixes, we've included
patches by Mario Kleiner to improve vblank handing which both improve the
timing accuracy and remove a few potential races -- provided you also
have the corresponding fixes in the kernel.
Bug fixes
---------
* Crash on hot-unpluging with an active fullscreen GL application, e.g. a
compositing WM or video player
https://bugs.freedesktop.org/show_bug.cgi?id=32770
* Freeze upon maximising client-side software renderers, e.g. flash.
https://bugs.freedesktop.org/show_bug.cgi?id=31367
* Fix confusion over G35 generation
https://bugs.freedesktop.org/show_bug.cgi?id=32478
Snapshot 2.13.902 (2010-12-10)
==============================
This is the first release candidate in preparation for the upcoming
2.14.0 release. Sandybridge support should be now be ready for use,
and we will appreciate any feedback we can get from this snapshot.
Improving the code base for Sandybridge should also have had knock
on effects for earlier chips as well, in particular Ironlake and to
a lesser extent i965.
New requirements compared to 2.13
---------------------------------
* Librdrm >= 2.4.23
Bug fixes
---------
* Crash after failing to allocate memory
https://bugs.freedesktop.org/show_bug.cgi?id=31487
* EFAULT during pwrite
https://bugs.freedesktop.org/show_bug.cgi?id=29752
* Mark outputs as on and restore backlight after mode-set
* A hang with i965+ with newer kernels.
Snapshot 2.13.901 (2010-11-05)
==============================
This is an intermediate snapshot of ongoing driver development. The
primary purpose of this snapshot is to capture some recent
improvements, (particularly in Sandybridge support), for further
testing.
Release 2.13.0 (2010-09-30)
===========================
We are pleased to announce this major release of the xf86-video-intel
driver, on schedule at 3 months since 2.12.0. With the many bug fixes
in this release, we encourage everyone using 2.12 to upgrade to 2.13.
[This release is functionally identical to the earlier 2.12.902
release candidate.]

Snapshot 2.12.902 (2010-09-28)
==============================
This is the second release candidate in preparation for the upcoming
2.13.0 release. The comes exactly one week after 2.12.902 and includes
only a handful of changes.
One significant change is that the drive now requires libdrm 2.4.22
(or newer), as several people reported compilation failures of
xf86-video-intel 2.12.901 with libdrm 2.4.21.
Other changes include a fix to compile for the 1.6 series X server, a
fix to retry framebuffer allocation after an initial failure, and a
fix to disable dri2 after fallbacks are forced on.

Release 2.12.0 (2010-06-24)
===========================
We are pleased to announce this major release of the xf86-video-intel
2D driver. It contains many correctness and performance improvements
compared to the 2.11 releases. We encourage everyone using 2.11 to
upgrade to 2.12.
[This release contains several bug fixes since the earlier 2.11.901
release candidate---see below for details.]
New requirements compared to 2.11
---------------------------------
* Libdrm >= 2.4.21
Major performance improvements
------------------------------
There have been many performance improvements targeting the
915G/945G/Pineview graphics chipsets (thank to Chris Wilson!). Areas
improved include:
* Major improvements to glyph rendering
* Avoid software fallback when using extended desktops, (for example,
video playback)
* Better performance when using large windows, (for example with
firefox scrolling)
* Avoiding migration ping-pong with gigantic drawing
The following speedups (measured with cairo-perf-trace/cairo-traces)
capture some of the improvements. These were measured on a Pineview
system with X server 1.8.1. This compares how this 2.12 release
improves performance compared to 2.11.0:
Trace Speedup
----- -------
ocitysmap 5.41x speedup
firefox-talos-gfx 2.41x speedup
gnome-terminal-vim 2.15x speedup
poppler 1.86x speedup
firefox-planet-gnome 1.43x speedup
midori-zoomed 1.39x speedup
swfdec-giant-steps 1.36x speedup
xfce4-terminal-a1 1.17x speedup
evolution 1.09x speedup
swfdec-youtube 1.06x speedup
Other improvements
------------------
Daniel Vetter improved Xvmc and overlay, adding GEM support.
Bug fixes
---------
There have been many conformance improvements targeting the
915G/945G/Pineview graphics chipsets. The rendercheck test suite
passes once again and there has been a significant reduction in the
number of errors detected by the cairo test suite (notably center
sampling and EXTEND_NONE behaviors are fixed).
Other notable bug fixes include:
* Fix for bug 28446 Garbled fonts with Mathematica
https://bugs.freedesktop.org/show_bug.cgi?id=28446
* Fixes for page-flipping and other DRI2-handling bugs, (Thanks Jesse
Barnes, and Kristian Høgsberg)
* Avoid corruption when using extended desktops, (for example, video
playback)
(The bug fixes below are new since the 2.11.901 release candidate)
* Fix corrupted output when screen rotated
https://bugs.freedesktop.org/show_bug.cgi?id=28461
* Fix corrupted rendering in KDE due to missing flush.
* Fixes i830_uxa_put_image for the following issues:
Bug 28569 - [i965] IGN's flash-based video player crashes X
https://bugs.freedesktop.org/show_bug.cgi?id=28569
Bug 28573 - [i965] Fullscreen flash and windowed SDL games fail to
update the screen
https://bugs.freedesktop.org/show_bug.cgi?id=28573
* Fix visual corruption of scrollbar in Chromium
* Fix tiling limits to resolve this issue:
Bug 28497 - Graphics corruption after opening a specific website
https://bugs.freedesktop.org/show_bug.cgi?id=28497
Snapshot 2.11.901 (2010-06-14)
==============================
This is the first release candidate in preparation for the upcoming
2.12.0 release. We will appreciate any feedback we can get from
testing of this snapshot to improve the 2.12.0 release.
New requirements compared to 2.10

Release 2.11.0 (2010-03-29)
===========================
New in 2.11: DRI2 and page flipping
-----------------------------------
The most significant new feature of this release is support for new
DRI2 APIs, allowing page flipping to occur for swaps that are
full-screen and not rotated.
Performance improvements in 2.11 compared to 2.10
Update the intel driver to 2.9.1 plus backports. 2.9.1 is the last version of the intel DDX that supports UMS (User modesetting), with 2.10 onwards being purely KMS only. As such, this driver contains backports of almost every correctness or performance related fix to the rendering layer in later intel drivers. This driver *REQUIRES* a GEM enabled kernel. it claims to support non-gem mode but this is essentially unmaintained and due to the way the abstraciton works is slow, if it works at all (it often does not). You have been warned. tested by many many people on tech over the last few weeks.
2010-05-10 16:32:28 -06:00
-------------------------------------------------
Update to xf86-video-intel 2.20.19. A recent kernel with kernel modesetting support is required. Thanks to jsg@ and kettenis@ for their work.
2013-03-18 12:38:18 -06:00
Dramatically improved performance of large pixmaps on
memory-constrained hardware, (such as 945), by using tiling.
Note that this fix is new since the most recent release
candidate for this release (2.10.903).
https://bugs.freedesktop.org/show_bug.cgi?id=25375
Elimination of software fallback with alpha-only pixmap (a fix which
eliminated a full second from the Moblin boot time):
https://bugs.freedesktop.org/show_bug.cgi?id=26189
Notable bug fixes in 2.11 compared to 2.10
------------------------------------------
Fix for undesired black borders on some images, (caued several
problems with firefox):
http://bugs.freedesktop.org/show_bug.cgi?id=17933
And other fixes to provide more conformance with existing
software-rendering, (as measures by the cairo test suite), such as the
sampling location for nearest-neighbor sampling.
Other changes
-------------
Eric Anholt and Daniel Vetter both removed large piles of old and
useless code now that the driver requires kernel modesetting
(KMS). This continues to reduce the mainteance burden of the driver,
making it easier to isolate and fix bugs.
Snapshot 2.10.903 (2010-03-22)
==============================
Some notable bug fixes
----------------------
* Fix unpredictable results in page-flipping code due to access of an
uninitialized variable.
* Two fixes that address a number of long-outstanding failures in the
cairo test suite:
Remove coord-adjust for nearest centre-sampling.
Fill alpha on xrgb images. Closes:
Bug 17933 - x8r8g8b8 doesn't sample alpha=0 outside surface bounds
http://bugs.freedesktop.org/show_bug.cgi?id=17933
* Fix a regression introduced in 2.10.902:
Fatal server error:
i915_emit_composite_setup: ADVANCE_BATCH:
under-used allocation 100/104
Bug 21723 [i915 bisected] rendering makes X crash
http://bugs.freedesktop.org/show_bug.cgi?id=27123
Other minor fixes (avoid trying to print an error message with a freed
string, set a variable to NULL after freeing), and documentation
updates are also included.
Snapshot 2.10.902 (2010-03-15)
==============================
Some significant bug fixes
--------------------------
Fix video color problems due to YUV plane ordering issue. This fixed a
regression that showed up recently (only in these release candidates).
Fix recent regression leading to corruption under compiz:
https://bugs.freedesktop.org/show_bug.cgi?id=26814
Further DRI2 improvements/fixes from Mario Kleiner and Jesse Barnes,
(including support for SwapBuffers request with divisor != 0).
Fix build against X server 1.6 branch.
Avoid flooding logs after an error occurs.
And dramatic code cleanups
--------------------------
Eric Anholt removed several cases of old, useless code, (conditions
that could not occur now that we require KMS, etc.).
Daniel Vetter eliminated piles of code by modernizing the XvMC
memory-management and completely removing the old i830_memory
allocator (i830_allocate_memory, i830_free_memory), etc.
Snapshot 2.10.901 (2010-02-26)
==============================
The most significant new feature of this release is support for new
DRI2 APIs, allowing page flipping to occur for swaps that are
full-screen and not rotated.
Some significant bug fixes
--------------------------
* Avoid fallback due to failing to extract pixel value from an
alpha-only solid, (this fix eliminated 1 second from Mobilin boot
time).
https://bugs.freedesktop.org/show_bug.cgi?id=26189
* Handle full-height blits without tearing in CopyRegion
https://bugs.freedesktop.org/show_bug.cgi?id=22475
Several other fixes and cleanups are included as well, (including the
removal of stale utility code that is now maintained in the separate
intel-gpu-tools module).
Release 2.10.0 (2010-01-04)
===========================
New requirements of 2.10 compared to 2.9
----------------------------------------
* Linux kernel with kernel-modesetting (KMS)
All user-modesetting code has now been removed from the driver.
We highly recommend kernel version 2.6.32 or later.
* Libdrm >= 2.4.16
New features in 2.10 compared to 2.9
------------------------------------
* New driver debugging options available in xorg.conf
(DebugFlushBatches, DebugFlushCaches, DebugWait). See "man intel"
for more details.
* Video overlay support with KMS. This currently requires Linux
2.6.33, but a backport to 2.6.32 is available here:
http://gitorious.org/daniel-s-linux-stuff/linux-kernel/commits/intel-kms-overlay-for-2.6.32
Notable fixes in 2.10 compared to 2.9
-----------------------------------
* Fix crash when XRenderComposite is called with a -1 value for
width/height, (crash at login when using compiz).
http://bugs.freedesktop.org/show_bug.cgi?id=24724
* Fix to support larger extended desktops, (such as a 2560x1600 plus a
1920x1200 monitor).
* Fix glyph corruption due to insufficient cache flushing:
https://bugs.freedesktop.org/show_bug.cgi?id=24315
Several other correctness and performance fixes are also included.
Note: The driver code of the 2.10.0 release is identical to that of
the 2.9.99.901 release candidate. The only changes in 2.10.0 compared
to 2.9.99.902 are a minor change to the configure script, and some
small updates to the documentation.
Update the intel driver to 2.9.1 plus backports. 2.9.1 is the last version of the intel DDX that supports UMS (User modesetting), with 2.10 onwards being purely KMS only. As such, this driver contains backports of almost every correctness or performance related fix to the rendering layer in later intel drivers.

2013-03-18 12:38:18 -06:00
Snapshot 2.9.99.902 (2009-12-10)
================================
This is the second release candidate in preparation for the upcoming
2.10.0 release. We will appreciate any feedback we can get from
testing of this snapshot to improve the 2.10.0 release.

Update to xf86-video-intel 2.20.19. A recent kernel with kernel modesetting support is required. Thanks to jsg@ and kettenis@ for their work.

Compared to the previous snapshot, this snapshot now correctly
verifies that libdrm 2.4.16 (or newer) is available. The previous
snapshot also required libdrm 2.4.16 for correct functionality, but
neglected to notify the user of this at configure, compile, or install
time and would instead simply fail to run.
Update the intel driver to 2.9.1 plus backports. 2.9.1 is the last version of the intel DDX that supports UMS (User modesetting), with 2.10 onwards being purely KMS only. As such, this driver contains backports of almost every correctness or performance related fix to the rendering layer in later intel drivers. This driver *REQUIRES* a GEM enabled kernel. it claims to support non-gem mode but this is essentially unmaintained and due to the way the abstraciton works is slow, if it works at all (it often does not). You have been warned. tested by many many people on tech over the last few weeks.

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).
Snapshot 2.8.99.901 (2009-09-09)
================================
This is the first release candidate in preparation for the upcoming
2.9.0 release. We will appreciate any feedback we can get from testing
of this snapshot to improve the 2.9.0 release.
See the commit log for changes in this release, and developers, please
provide me summaries for any major features in this release that you
think should appear in NEWS and in the 2.9.0 release notes.
Note: We are still investigating failures with 865G chipsets, (these
failures existed in the 2.8 series as well). We are hoping to fix
these failures before the 2.9.0 release.
Release 2.8.0 (2009-07-20)
==========================
We are pleased to present this major release of the xf86-video-intel
driver. This release is very similar to the 2.7.99.902 release
candidate but includes a couple of additional bug fixes, (for bugs
#22760 and @22483).
Compared to the 2.7 releases this driver contains several new features
and many bug fixes. The driver now depends on X server 1.6 or later,
and eliminates several obsolete code paths, (XAA and EXA removed in
favor of UXA, DRI1 support eliminated). The driver certainly will work
best with an i915 module from a recent kernel (2.6.31) and with
kernel-modesetting (KMS, specified by loading i915 with the option
"modeset=1").
New features in 2.8.0 compared to 2.7
-------------------------------------
* Remove XAA/EXA/DRI1 and NoAccel, and only support UXA/DRI2 now
(requiring xserver 1.6).
* VLD support added into XvMC for Mpeg2, which decreases CPU usage
when playing video.
Major fixes in 2.8.0 compared to 2.7
------------------------------------
* Fix broken front-buffer rendering
https://bugs.freedesktop.org/show_bug.cgi?id=19174
* Fix disabling of XvMC disabled
https://bugs.freedesktop.org/show_bug.cgi?id=20790
* Fix broken VT switch on some machines
https://bugs.freedesktop.org/show_bug.cgi?id=19578
* Improve performance of trapezoid rendering for UXA
https://bugs.freedesktop.org/show_bug.cgi?id=21376
* Vblank sync'd GL buffer swap (fixing video tearing under composite)
https://bugs.freedesktop.org/show_bug.cgi?id=20664
* Fix G41 DRM support
https://bugs.freedesktop.org/show_bug.cgi?id=21095
* Fix crash on some 8xx
https://bugs.freedesktop.org/show_bug.cgi?id=18974
Various fixes for GPU hangs, and more...
Snapshot 2.7.99.902 (2009-07-13)
--------------------------------
This is the first release candidate in preparation for the upcoming
2.8.0 release. Most major and critical bugs should be fixed, but some
minor bugs may still be present. We will appreciate any feedback we
can get from testing of this snapshot to improve the 2.8.0 release.
Snapshot 2.7.99.901 (2009-06-10)
--------------------------------
This is the first release candidate in preparation for the upcoming
2.8.0 release. Most critical bugs should be fixed, but some major
bugs may still be present. We will appreciate any feedback we can
get from testing of this snapshot to improve the 2.8.0 release.
Some of the major fixes in this snapshot include:
* Several fixes for intermittent GPU hangs/crashes, (some of
which already appeared in the 2.7.1 release)
* Fix to avoid X crash when viewing large images in browser
* Fix X server failure when running old (non-GEM) kernel
* Fixes for SDVO LVDS mode detection
* Fix major performance regression of trapezoid rendering
compared to XAA/EXA
* New support for tear-free video when using KMS
* New support for tear-free DRI2 CopyRegion
Snapshot 2.7.99.1 (2009-04-28)
------------------------------
This is a development snapshot very early in the process toward
developing 2.8. There have been some big changes to the code, and
we're anxious to get feedback on these changes as early as possible.
Here is a summary of the biggest changes:
* Driver now depends on X server 1.6 or later
* Eliminate XAA and EXA support (in favor of UXA)
* Eliminate DRI1 support
* Fixes for running without DRI at all
These code removals represent a deletion of a substantial amount of
code, (and hopefully piles of bugs), as well as reduce the maintenance
effort going forward as the number of combinatorial configurations for
the driver are greatly reduced. This means that users are much more
likely to be running code that has actually been tested, and it will
be much easy for developers to replicate bugs that users experience.
One of the things that would be most useful in testing this release is
to revisit any outstanding bugs that you have previously reported. If
the buggy behavior is gone, (or the bug is no longer relevant---such
as a bug that's specific to XAA only), please feel free to indicate so
in bugzilla or even just close the bug.
If you confirm that the bug is still present, please indicate so in
the bug report. (I was going to ask that you select a 1.7.99 version,
but it looks like bugzilla only has versions for products not
compoenents, while we use a "xorg" product and a "driver/intel"
component.) We definitely want to make any such confirmed bugs a
priority, so it would be nice to have a consistent mechanism to search
for these bugs. Suggestions are welcome on the best approach.
Thanks in advance for any testing or feedback on this snapshot.
update to xf86-video-intel 2.7.1. Tested by many.

Release 2.7.0 (2009-04-15)
--------------------------
Compared to the 2.6 series, 2.7.0 has a large number of bug fixes, but
also a few significant features, such as:
SDVO-TV support, available on ADD2 card (bug#9992) and
D945GCLF2 board (bug#17776).
Basic SDVO-LVDS support
XV video display without tearing
[Though this isn't working for all users yet, see
https://bugs.freedesktop.org/show_bug.cgi?id=21076 ]
Various fixes for UXA, DRI2, and Kernel modesetting.
We encourage users to use kernel modesetting and UXA acceleration with
this release, which should give the best performance and
robustness. When KMS is available, UXA is the default acceleration
used by the driver, (EXA is the default otherwise).
Known issue:
Some Linux kernel versions (such as 2.6.29) are known to have
broken PAT code that causes recent versions of this driver to
fail, (which can manifest as the X server simply not
starting). This can be verified by adding the "nopat" option
to the kernel command-line and seeing the failure go away. We
hope that newer kernels in the 2.6.29.x as well as 2.6.30 and
above will have working PAT code.
Some of the most notable bugs fixed in 2.7.0 include:
