Snapshot 2.99.916 (2014-09-08)
|
|
==============================
|
|
Quick update for MST in UXA - we need to hook up the RandR outputs for
|
|
dynamicaly added connectors.
|
|
|
|
|
|
Snapshot 2.99.915 (2014-09-08)
|
|
==============================
|
|
A significant change to UXA to enable MST and to keep it working on recent
|
|
kernels needs some soaking before a major release, and the usual
|
|
plethora of bugfixes. One other feature is the support for hardware
|
|
rotations on very recent kernels.
|
|
|
|
* Handle rotated scanouts that are all clear correctly. The region to
|
|
update was not being computed correctly, overdrawing the wrong CRTC.
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=81820
|
|
|
|
* Reset cursor images after rotation and size changes

https://bugs.freedesktop.org/show_bug.cgi?id=82337
|
|
|
|
* Handle stale DRI2 buffers and Client errors more gracefully
|
|
|
|
* Fallback if we fail to render a glyph onto a too-large surface, e.g.
|
|
direct rendering of glyphs onto extended desktops with gen2/gen3.
|
|
https://bugs.archlinux.org/task/40949
|
|
|
|
* Further work to enable tiled rendering onto large surfaces in
|
|
severely aperture and memory constrained devices (e.g. gen2/gen3)
|
|
|
|
* Honour the Primary option from xorg.conf and mark that as the RandR
|
|
primary.

|
|
https://bugs.freedesktop.org/show_bug.cgi?id=82205

|
|
* Fix another Client-Window DRI2 close race
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=82979
|
|
|
|
* Fix incorrect discarding of GPU damage when copying over the TearFree
|
|
scanout - which caused a flicker in rapidly updated elements (like
|
|
simple video panes).

Snapshot 2.99.914 (2014-07-23)
|
|
==============================
|
|
And a brown paper bag to hide the rebuilding from the tarball with
|
|
'autoreconf -fi' error that arose from not distributing the libobj/
|
|
directory.
|
|
|
|
|
|
Snapshot 2.99.913 (2014-07-23)
|
|
==============================
|
|
This should be it... A few fixes from testing the new code, we should be
|
|
ready for the final release. However, we do have one standout feature in
|
|
this snapshot, we now officially recognise HD Graphics 5300/5500/5600,
|
|
Iris Graphics 6100 and Iris Pro Graphics 6200/P6300 (formerly known as
|
|
Broadwell).
|
|
|
|
* Check the window actually covers the CRTC before doing a single CRTC flip,
|
|
and then restore the right framebuffer after completing CRTC flips.
|
|
Otherwise we would detect an error and disable an output under TearFree
|
|
Regression in 2.99.912

|
* Check that the damage still exists after implicit reduction
|
|

|
|
|
|
* Fix direction flags for fallback composited CopyAreas which
|
|
caused scrolling corruption in a few configurations
|
|
Regression from 2.20.0
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=79843
|
|
|
|
* Do not throw away damage if there is no redundant copy

|
* Check clipping on PolyRect before discarding the clipped damage
|
|

|
|
https://bugs.freedesktop.org/show_bug.cgi?id=79992
|
|
|
|
* Fix hints for GLXPixmapa, as these are never swapped and so
|
|
miss invalidating the hints on SwapBuffers with the result
|
|
that they are often presumed blank
|
|
Regression in 2.99.912
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=79999
|
|
|
|
* Fix incoherent choice of source bo when constructing 8x8 tiles,
|
|
incorrect pattern origin when extracting, and then fix the
|
|
alignment of colour patterns for BLT operations
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=80033
|
|
|
|
* Disable blending with the render engine on snoopable buffers
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=80253
|
|
|
|
* Restore throttling to prevent client lag under heavy GPU load
|
|
Regression from 2.21.10
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=77436
|
|
|
|
* Use ClientGone for notifications on shared DRI2 windows to prevent
|
|
rare crashes due to use-after-free of the swap requests
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=80157
|
|
|
|
* Ensure the mmaped CPU bo is idle before migrating damage
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=80560
|
|
|
|
* Fix incorrect clipping by the render engine for large DRI2 windows
|
|
|
|
* Ensure that the aperture tiling fallbacks are bounded
|
|
|
|
* Validate parameter to xf86-video-intel-backlight-helper more carefully
|
|
(CVE-2014-4910)
|
|
|
|
* Fix slaved scanouts for reverse optimus, though rotated slaves will
|
|
require further patches to Xorg.
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=81383
|
|
|
|
* Fix build without Composite extension.
|
|
|
|
* Fix build without gettline().
|
|
|
|
* UXA: Allocate and resize frontbuffer consistently to pass sanity checks
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=80088
|
|
|
|
* UXA: Report cached backlight value when the output is off (like sna)
|
|
https://bugzilla.redhat.com/show_bug.cgi?id=1032978
|
|
|
|
* UXA: Mark outputs as off before the kernel does (like sna)
|
|
This will prevent the internal panel from starting up blank in some
|
|
multi-monitor configurations
|
|
https://bugzilla.redhat.com/show_bug.cgi?id=1103806
|
|
|
|
Note that the DRI2 exchange mechanism introduced in 2.99.912 exposes bugs
|
|
in some compositors, at least kwin and comptom, which discard DRI2 buffer
|
|
invalidates rather than resourcing their texture. For example,
|
|
https://bugs.kde.org/show_bug.cgi?id=336589
|
|
|
|
Note that the improved triple buffering introduced in DRI2 requires a patch
|
|
to Xorg (now released upstream) to prevent crashes with DRI_PRIME.
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=80001
|
|
|
|
Note that DRI3/Present require tracking the relevant development trees for
|
|
mesa and the xserver as they are very much still under early testing. Also
|
|
be aware that Mesa provides no support for explicit fencing so Damage
|
|
tracking between compositors and clients is unserialised.
|
|
|
|
|
|
Snapshot 2.99.912 (2014-06-10)
|
|
==============================
|
|
A final round of features. We have everything from support for variable
|
|
cursor sizes, support for the DRI3 and Present extensions, improved DRI2
|
|
support, support for Xserver 1.16, userptr from kernel 3.16, and
|
|
precursory support for DP multistream transport,
|
|
|
|
* Avoid discarding dirty pixels when promoting a migration to cover the
|
|
whole pixmap.
|
|
Regression in 2.99.911
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=77063
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=77178
|
|
|
|
* Avoid overextending degenerate lines (and consequentially accessing
|
|
pixels outside of our damaged area).
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=77074
|
|
|
|
* Fix subpixel glyph rendering on gen2 devices (830-865 chipsets)
|
|
Regression in 2.99.911
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=77201
|
|
|
|
* Share the global pixman glyph cache between ZaphodHeads
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=54707
|
|
|
|
* Light up all connected outputs, even if their status is unknown, on
|
|
takeover from fbcon. This prevents loss of display after a resume
|
|
on recent kernels, for example.
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=77768
|
|
|
|
* Show the video overlay (when supported by the hardware) across all
|
|
outputs.
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=77802
|
|
|
|
* Do not discard damage when performing "BLT" spans inplace with the CPU.
|
|
Regression from 2.20.10
|
|
|
|
* Avoid discarding IO buffers too early during their preparation for a
|
|
new batch
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=79238
|
|
|
|
* Fix fallback handling for displaying large scaled framebuffers (that
|
|
are too large to be scaled by the GPU in a single pass)
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=79320
|
|
|
|
* Listen to external modifications of backlight value and propagate
|
|
the notifications to RandR clients. This should make the GUI report
|
|
ACPI keypresses to change the backlight correctly.
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=79699
|
|
|
|
* UXA: fix pageflips with 3 heads.
|
|
|
|
* UXA: do not report a BadMatch error for DRI2GetMsc - as clients are
|
|
often unprepared and die when they get the unexpected error.

Snapshot 2.99.911 (2014-03-19)
|
|
==============================
|
|
Hans de Geode has been working on making the Xserver work without
|
|
privileges under the supervision of systemd/logind. This necessitated a
|
|
few new features for us: server fds (where we are passed which fd to use
|
|
to talk to our device by the Xserver who may in turn receive it from
|
|
logind or other host) and a small backlight helper so that we can continue
|
|
to provide a RandR backlight property when running without root privileges.
|
|
|
|
* Flush when changing blend modes on Ironlake, or else single glyphs
|
|
are sometimes rendered incorrectly
|
|
Regression from 2.20.15
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=74882
|
|
|
|
* Fix pixmap offsets for pixman fallbacks onto Composite redirected
|
|
windows
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=73811
|
|
|
|
* Fix blending onto 8-bit destinations, typically used for generating
|
|
masks in complex Render operations, on gen2
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=75818
|
|
|
|
* Handle failure to create DRI bo more carefully. For example on gen3,
|
|
the DDX supports pixmaps that are much, much larger than OpenGL can
|
|
use and do not support the tiling modes that we request for OpenGL.
|
|
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1289049
|
|
|
|
* Fix a bookkeeping bug with proxy buffers that are marked active but
|
|
not actually inserted into a request (so they end up permanently
|
|
active and confuse everybody).
|
|
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1289923
|
|
|
|
* Actually turn off displays with DPMS off for UXA.

Snapshot 2.99.910 (2014-02-10)
|
|
==============================
|
|
Another latent bug exposed by recent changes merit another snapshot for
|
|
final testing.
|
|
|
|
* Only discard damage when overwriting the dirty CPU bo, instead
|
|
of discarding damage that will be shown!
|
|
|
|
* Reset operation state when switching between glyph caches.
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=74494
|
|
|
|
* Fully reinitialise pixmaps allocated from the freed cache. Fixes
|
|
a potential issue (crash or misrendering) when using some compositors.
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=74550
|
|
|
|
* Do not expose the TexturedVideo adaptor in UXA when it is disabled
|
|
either due to a hung GPU or explicitly disabled by the user.
|
|
|
|
* Restore the pipe stall when changing CC state on gen6, otherwise
|
|
the GPU may not flush intermediate results from all EU resulting
|
|
in render corruption (usually the occasional black box).

Snapshot 2.99.909 (2014-02-01)
|
|
==============================
|
|
Pass the brown paper bag. Ridiculously stupid bug in last minute coding.
|
|
|
|
* Add Xv support using glamor acceleration in addition to adaptors
|
|
provided by the UXA backend.
|
|
|
|
* Fix overeager discarding of CPU damage

|
Snapshot 2.99.908 (2014-01-31)
|
|
==============================
|
|
A couple of regressions dashed the hopes that .907 was to be the final
|
|
release candidate, so time to start the cycle again after applying a few
|
|
more bugfixes.
|
|
|
|
* Fix invalid pageflipping of GLXPixmaps by UXA.
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=73282
|
|
|
|
* Consistently treat DPMS Suspend/Standy as Off, otherwise we may
|
|
incorrectly restore the backlight in UXA.
|
|
|
|
* Fix disabling the backlight in UXA when querying the value whilst off
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=73181.
|
|
|
|
* Invalidate between every operation if rendering into the source or mask.
|
|
Fixes regression in 2.99.907 on Ivybridge (seen in KDE)
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=73208
|
|
|
|
* Check for available batch buffer state before restoring state on gen4,
|
|
otherwise we overwrite surface state with commands and cause a GPU hang.
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=73348
|
|
|
|
* Prevent an invalid free by TearFree
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=73469
|
|
|
|
* Fix confusion in TearFree when it tried to pageflip to a stale bo
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=70905
|
|
|
|
* Initialise TearFree contents with the current frontbuffer upon creation,
|
|
otherwise old content may be visible for significant fractions of a
|
|
second after resume or DPMS on
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=73842
|
|
|
|
* Nullify the old pointer into a CPU mmapping of the bo when promoting it
|
|
on the GPU. Eventually that old pointer becomes invalid and will cause
|
|
the Xserver to crash.
|
|
Fixes regression in 2.99.906
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=73351
|
|
|
|
* Restore the serialNumber on the GC correctly after falling back to
|
|
software. This was seen to cause corruption with Wine.
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=73856
|
|
|
|
* Do not ignore CPU damage on a pixmap unless the Composite operation
|
|
will completely overwrite it. This was observed in xfce4.
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=69528
|
|
|
|
* Skip fake outputs during initial probe as they can cause a NULL pointer
|
|
dereference.

|
|
==============================
|
|
The highlight here is that things seem to be quietening down on the bug
|
|
reporting front. All is not quiet as you will see below, and maybe it is
|
|
just the holiday season that is approaching*, but there has been a
|
|
remarkable falloff in bug reports. Lets hope this trend holds and we can
|
|
make a stable release shortly!
|

Snapshot 2.99.905 (2013-10-23)
|
|
==============================
|
|
The highlight for this snapshot is the extension of TearFree to support
|
|
transformed outputs, along with some polishing to eliminate its impact
|
|
upon input and output latency. As always, thanks to everyone who have
|
|
been testing, reporting bugs and helping to improve the stability before
|
|
release.

Snapshot 2.99.904 (2013-10-09)
|
|
==============================
|
|
There is one more feature planned to be completed for 3.0, so time for a
|
|
snapshot beforehand to push out the bug fixes from the last week.
|
|
|
|

|
|
|
|
* Apply more restrictive tile constaints for 915g class devices
|
|
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1232546

|
|
|
|
* Prevent discarding active upload buffers, causing glitches in chromium
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=66990
|
|
|
|
* Prevent specifying a negative timeout to select if the BlockHandler
|
|
takes too long to update the display
|
|
|
|
* Promote the Ironlake pipecontrol to be a full pipeline flush to
|
|
prevent render cache corruption

|
|
|
|
|
|
Snapshot 2.99.903 (2013-09-28)
|
|
==============================
|
|
Lots more stabilization work, not yet peaceful enough to christen 3.0. We
|
|
have everything ranging from build fixes for systems like Suse Linux
|
|
Enterprise Desktop that like to backport hardware enablement to ancient
|
|
packages, to fixes for hardware enabling, and some more performance tuning.
|
|
|
|
* Fix VSync on Haswell.
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=69119
|
|
|
|
* Disable Y-tiling on gen4 - it too frequently leads to instability.
|
|
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1222203
|
|
|
|
* Disable same EDID detection based on property id - the kernel likes
|
|
to reuse ids leading to a failure to detect the right modes on a monitor
|
|
change.
|
|
|
|
* Avoid issuing multiple DPMS requests to the same encoder (alised to
|
|
multiple connectors) to avoid upsetting Haswell and leaving the
|
|
screens blank.
|
|
|
|
* Honour the user preferrence for the initial mode, even if they are
|
|
being silly
|
|
https://bugzilla.novell.com/show_bug.cgi?id=841696
|
|
|
|
* Clear the clear hint when apply DRI updates - to prevent some
|
|
screenshots from GL windows being left blank.
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=69730
|
|
|
|
* Prevent a NULL dereference from trying to undo an non-existent buffer
|
|
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1228677
|
|
|
|
* Handle out-of-memory conditions far more gracefully. If the system is
|
|
hard against the memory wall, then the kernel will start issuing
|
|
SIGBUS even for CPU mmaps. Untrapped these will cause X to die.

Snapshot 2.99.902 (2013-09-07)
|
|
==============================
|
|
We do not condone or support Canonical in the course of action they have
|
|
chosen, and will not carry XMir patches upstream.
|
|
-The Management
|
|
|
|
Snapshot 2.99.901 (2013-09-04)
|
|
==============================
|
|
What's this? A pre-release snapshot of an upcoming 3.0 major release?
|
|
What could be the big new feature about to land? SNA by default!
|
|
Not only that, we also have a preview of the XMir integration patches.
|
|
|
|
Whilst we consider the SNA acceleration method to be ready to take over
|
|
from UXA (the current acceleration method), it still remains possible to
|
|
switch over to the old method with the following xorg.conf snippet:
|
|
Section "Device"
|
|
Identifier "Device0"
|
|
Driver "intel"
|
|
Option "AccelMethod" "UXA"
|
|
EndSection
|
|
|
|
The promise of SNA is that it improves the user experience by providing a
|
|
faster, more fluid, desktop, that is both more power efficient and less
|
|
prone to crashes than UXA. If it still fails to meet your expections,
|
|
please file bugs!
|
|
|
|
|
|
Release 2.21.15 (2013-08-21)
|
|
============================
|
|
Some build fixes for the BSDs and alternate compiler, and conflicting
|
|
configure options and a critcial fix for some PRIME setups.
|
|
|
|
* Don't fail to configure if DRI1 is not available and the user asks
|
|
for both DRI and KMS-only
|
|
[Regression from 2.21.14]
|
|
|
|
* Lots of miscellaneous fixes for older gcc, other compilers and BSD.
|
|
|
|
* Initial framework support for hosted X.
|
|
|
|
* Improve transition from fbcon to X with multiple outputs and extended
|
|
desktops.
|
|
|
|
* Ensure the framebuffer exists before checking it against the CRTC
|
|
constraints.
|
|
https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/121234
|
|
[Regression from 2.21.10]
|
|
|
|
* Add RGB overlay support for Ironlake and later.
|
|
|
|
* Don't release the overlay buffer too early, i.e. before the client
|
|
disables the Xv image.
|
|
|
|
* Tweak the ring switching logic to reduce use of semaphores on
|
|
Sandybridge and later - a delicate balancing act between trying to
|
|
use the faster engine for the task and preventing concurrent use of
|
|
multiple rings.
|
|
|
|
|
|
Release 2.21.14 (2013-08-04)
|
|
============================
|
|
A few updates for the top-end Haswell systems (notably GT3 and GT3e
|
|
systems), in particular, setting the appropriate thread counts for the
|
|
larger GPU and handling a few scaling issues with the emedded DRAM. More
|
|
important than the performance tuning though is a fix for a critical
|
|
issue encountered by a few people on gen4/gen5 systems.
|
|
|
|
* Initial performance tuning for HSW:GT3e
|
|
|
|
* Fix a crash with Planetary Annihilation
|
|
|
|
* Disable triple buffering for compositors
|
|
|
|
* Reserve space in the exec buffer array for deferred VBOs.
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=67504
|
|
|
|
|
|
Release 2.21.13 (2013-07-27)
|
|
============================
|
|
A minor release to repair the build for non-Linux systems, and to undo a
|
|
few more regressions.
|
|
|
|
* Avoid potential memory corruption with allocations of very small
|
|
depth 1 bitmaps.
|
|
|
|
* Fix source clipping whilst computing copy extents and exposures.
|
|
[Regression from 2.21.12]
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=66970
|
|
|
|
* Use /proc/cpuinfo if cpuid4 is not available (old hardware or old
|
|
gcc), and repair the build on systems without cpuid.
|
|
[Regression from 2.21.12]
|
|
|
|
* Fix performance regression on Ironlake from inadvertently flushing
|
|
after every operation.
|
|
[Regression from 2.21.11]
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=67157
|
|
|
|
* Fix conflict handling when probing initial KMS configuration for
|
|
ZaphodHeads.
|
|
[Regression from 2.21.11]
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=67176
|
|
|
|
* Stop being overly restrictive and rejecting stale DRI2 buffers.
|
|
(DRI2 is inherently racy in that the client may have completed and
|
|
submitted rendering to buffers that are now invalid on the server.
|
|
This race is magnified by bugs within the Xserver where it forgets
|
|
to notify the DRI2 clients of certain invalidation events.)
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=67210
|
|
|
|
* Handle a failure to use a GTT mmap for a pixmap upload and try
|
|
an alternative method before giving up.
|
|
|
|
|
|
Release 2.21.12 (2013-07-14)
|
|
============================
|
|
In this release, we clear up the teething troubles from preserving the KMS
|
|
configuration, notably external connections on Haswell and plugging in new
|
|
outputs after startup were broken. Besides these regression fixes, there
|
|
are a couple of fixes for some long standing issues, such as incorrect
|
|
rendering on gen2, an infinite loop with very, very large pixmaps and a
|
|
slight improvement to the tempermental gen4.
|
|
|
|
* Allow untiled scanouts again (required for large extended desktops on
|
|
gen2 and gen3).
|
|
[Regression from 2.21.11]
|
|
|
|
* Use the correct count of the number of dirty damage boxes for the quick
|
|
check on whether the existing damage contains the requested area.
|
|
The danger is that we may get a false result and skip migration and so
|
|
cause pixmap corruption (in the unlikely event that the application
|
|
frequently causes fallbacks).
|
|
[Regression from 2.21.11]
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=66430
|
|
|
|
* Fix initial connection probing for multi-function encoders, such as the
|
|
external connections on Haswell.
|
|
[Regression from 2.21.11, initial connection probing]
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=66488
|
|
|
|
* Fix gen2 rendercopy into a8 surfaces, for example, glyph uploads into
|
|
the glyph cache.
|
|
|
|
* Fix detection of user overrides for initial connection configuration.
|
|
The code used the xorg-server-1.15 values, having missed the
|
|
introduction of ZoomModes into that release.
|
|
[Regression from 2.21.11, initial connection probing]
|
|
|
|
* Always initialise the gamma ramp, even on unconnected CRTCs.
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=66563
|
|
[Regression from 2.21.11, initial connection probing]
|
|
|
|
* Some more tuning of the gen4 vertex corruption workaround. The root
|
|
cause behind the GPU using incorrect texture coordinates is still
|
|
not solved, but by reducing the maximum number or rectangles in
|
|
flight through the GPU we reduce the likelihood of corruption.
|
|
|
|
* Fix compilation with gcc-4.5
|
|
[Regression from 2.21.11]
|
|
|
|
* Avoid integer overflow when performing tiled uploads and operations
|
|
on very large (>28k pixels wide or tall pixmaps)

Release 2.21.11 (2013-06-30)
|
|
============================
|
|
An eventful week. What started with a regression with some builds of
|
|
firefox on some machines lead ultimately to the discovery of an older
|
|
kernel bug. Aside from the work to fix the image bug and a few other
|
|
older bugs that were reported and resolved this week, there is also a
|
|
(hopefully) subtle change to the initial configuration of displays. In
|
|
the absence of user overrides in xorg.conf, the DDX will try to preserve
|
|
the same display configuration as used by the kernel, which hopefully
|
|
will be the same configuration as setup by the BIOS. The result should
|
|
be a boot sequence that does not resize at all (aka fastboot) - until
|
|
the display manager takes over and loads a completely different
|
|
configuration!
|
|
|
|
* Add reference counting of drmMaster for ZaphodHeads
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=66041
|
|
|
|
* Add a GPU flush before changing blend modes on Ironlake

|
* Fix compilation of UXA with xorg-xserver < 1.10
|
|
[regression from 2.20.0]
|
|
|
|
* Fix consideration of gradients for deciding when to migrate render
|
|
operations

which affects kernels 3.7 - 3.10, coming to a stable kernel near you soon.
|
|
|
|
|
|
Release 2.21.10 (2013-06-22)
|
|
============================
|
|
Fixes missing support for Xv (with the textured video adaptor) on
|
|
Haswell, and an old bug with wide monitors on various generation. Along
|
|
with a few other regression fixes and performance tweaks for various
|
|
corner cases.
|
|
|
|
* Do not lose track of fast pageflips across mode changes
|
|

Release 2.21.9 (2013-06-06)
|
|
===========================
|
|
Consolidating the copy-on-write support, hopefully cleaning up the last of
|
|
the regressions.
|
|
|
|
* Restore vsync on textured videos.
|
|

|
|

|
|
light them up.

Release 2.21.8 (2013-05-27)
|
|
===========================
|
|
A quick release to cleanup a few regressions from the introduction of
|
|
copy-on-write support, notably hitting wine applications and a memory
|
|
leak for firefox.
|
|
|
|
* Only mark a PolyFillRect operation as replacing if it is unclipped

|
|
|
Release 2.21.7 (2013-05-21)
|
|
===========================
|
|
A couple of weeks turned into a month and a couple of weeks... Amidst
|
|
the usual bug fixes, we have added the complete set of Haswell PCI IDs -
|
|
hopefully future proofing ourselves against being surprised by new
|
|
products. We can also now use the correct term for the top of the range
|
|
Haswell variants, GT3.
|
|
|
|
* Fix several assertion failures hit by Jiri Slaby.
|
|
|
|
* Allow XvMC to also target overlay/sprite planes.
|
|
|
|
* Throw in a paranoid MI_FLUSH between BLT and RENDER operations on
|
|
Ironlake.
|
|
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1168066
|
|
|
|
* Prevent reuse of old framebuffers after a resize.
|
|
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1157678
|
|
|
|
* Fix compilation with --enable-valgrind and no --enable-debug
|
|
|
|
* Improve partial migration of render sources.
|
|
|
|
* Fix origin of trapezoids.
|
|
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1178020
|
|
|
|
* Introduce copy-on-write support for cloning pixmaps. The ultimate
|
|
goal here is to efficiently support the TearFree mode of operation,
|
|
but this provides immediate benefits with firefox - most importantly
|
|
because of the inefficient way it now implements scrolling.
|
|
|
|
|
|
Release 2.21.6 (2013-04-06)
|
|
===========================
|
|
A surprising highlight of this release is a little refresh to the KMS
|
|
support for OpenBSD. OpenBSD now has its own KMS implementation which is
|
|
mostly compatible with the interface in Linux, with one or two tweaks
|
|
supplied by Mark Kettenis. This release continues to cleanup behaviour
|
|
for Haswell.
|
|
|
|
* Workaround a failure by the xserver to invalidate DRI buffers
|
|
following a pixmap change for XComposite redirection.
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=62614
|
|
|
|
* Fix computation of clip extents for stippling
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=62618
|
|
|
|
* Support KMS on OpenBSD, by Mark Kettenis
|
|
|
|
* Clean up sockets upon CloseScreen (making ourselves better behaved
|
|
for muxed setups).
|
|
|
|
* Fix the tests for AVX/AVX2 support in CPUID and remember to check for
|
|
OS support as well.
|
|
|
|
* Report a monotonic UST value for undisplayed drawables rather than 0
|
|
by Daniel Kurtz
|
|
|
|
* Fix video playback on gen4 through a complex clip (more gen4 GPU woes)
|
|
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1162046
|
|
|
|
|
|
Release 2.21.5 (2013-03-21)
|
|
===========================
|
|
Haswell reintroduces a command to load the scanline window from the
|
|
command stream and so requires its own specialised wait-for-vsync routine
|
|
- failure to do so was then causing hangs when trying to do tearfree video
|
|
or use a compositor.
|
|
|
|
* Prevent buffer leak if a non-fullscreen Window is closed with multiple
|
|
pending swap events.
|
|
|
|
* Fix offset transformation for fallback gradient paths.
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=62198
|
|
|
|
* Prevent Glamor from crashing if misconfigured.
|

|
|
* Prevent UXA from crashing if torn down during PreInit.
|
|
Thanks to Aaron Plattner.
|
|
|
|
* Prevent miscompilation with different functional units having different
|
|
compiler flags. Some functions were expected to be inlined and so
|
|
recompiled with the current target. However, some compilers were
|
|
choosing to emit subroutine calls instead without noticing that the
|
|
ABI was different between the caller and callee - causing corruption.

Release 2.21.4 (2013-03-11)
|
|
===========================
|
|
More bugs, more fixes, more releases. A minor new feature being introduced
|
|
is the runtime detection of CPU instructions sets along with specialised
|
|
paths to take advantage of the available CPU.
|
|
|
|
* Honour LinearFramebuffer for clumsy PowerXpress integration
|
|
|
|
* Disable read-read optimisations of mappings whilst the root
|
|
cause of a corruption issue remains elusive.
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=61628
|
|
|
|
* Disable 8-bpp framebuffers in UXA as the regressions therein
|
|
remain unfixed.
|
|
|
|
* Restart vertex checks after lock contention
|
|
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1124576
|
|
|
|
* Handle Screen Pixmap recreation whilst exported via PRIME.
|
|
|
|
* Correct application of scale factors to video source offsets.
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=61610
|
|
|
|
* Chain up CloseScreen so that resources are actually freed across regen
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=56608
|
|
|
|
* Fix Haswell CRW PCI-IDs
|
|
|
|
* Handle batch submission failure during DRI copies
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=61708
|
|
|
|
* Probe for kernel support of requested Screen depth
|
|
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1135403
|
|
|
|
* Correct GPU limits for early gen2 and gen3 architectures and prevent
|
|
an infinite recursion for particular image sizes.
|
|
|
|
|
|
Release 2.21.3 (2013-02-20)
|
|
===========================
|
|
A few minor bugfixes, another point release.
|
|
|
|
* Fix tracking of DRI pixmaps and their backing bo across reparenting. If
|
|
we tried to execute a SwapBuffers after a Window was reparented, but
|
|
before the DRI client has updated its references, then we would end up
|
|
manipulating an exported pixmap without a flush flag set. In the worst
|
|
case, this would culminate in a segfault in the driver.
|
|
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1127497
|
|
|
|
* Restore the gen4 workarounds for flickering rendering - a few cases still
|
|
remain, as the root cause persists.
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=60402
|
|
|
|
* Double check that the device has KMS enabled before claiming. This allows
|
|
X to gracefully fallback to VESA/fbdev rather than bailing out.
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=60987
|
|
|
|
* Fix the UXA render programs for projective transforms on Ivybridge.
|
|
|
|
|
|
Release 2.21.2 (2013-02-10)
|
|
===========================
|
|
Pass the brown paper bags, I need half a dozen or so. That seemingly
|
|
innocuous build fix with xorg-1.13 happened to have the little side-effect
|
|
of breaking glyph rendering with xorg-1.12 and older on 64-bit machines.
|
|
|
|
|
|
Release 2.21.1 (2013-02-10)
|
|
===========================
|
|
A fix for a potential GPU hang on 945gm (GMA950) and earlier chipsets,
|
|
along with backporting SNA to the packages found in stable distributions
|
|
like Debian 6.0 (Squeeze).
|
|
|
|
* Cleanup compilation warnings from deblint, thanks to Paul Menzel
|
|
|
|
* Minor build improvements by Damien Lespiau.
|
|
|
|
* Disable generating span geometry for non-rectilinear spans on gen4
|
|
in order to work around and prevent one class of render corruption.
|
|
|
|
* Prevent cache thrashing and severe performance degradation on LLC
|
|
machines for streaming texture updates. However, note the effect was
|
|
only observed on just one particular laptop.
|
|
|
|
* Fix alignment of subsurface proxies for old chipsets.
|
|
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1120108
|
|
|
|
* Repair build against Xserver-1.6 and contemporary packages.
|
|
|
|
|
|
Release 2.21.0 (2013-02-01)
|
|
===========================
|
|
A few new features:
|
|
|
|
* Enable render acceleration for Haswell GT1/GT2.
|
|
|
|
* Enable multi-threaded rasterisation of trapezoids and fallback composition
|
|
|
|
* Utilise a new kernel interface (v3.9) for processing relocations
|
|
|
|
along with a few older features from the 2.20.x series:
|
|
|
|
* PRIME support for hotplug GPUs and hybrid systems
|
|
|
|
* Support for IvyBridge GT1 machines, aka HD2500 graphics.
|
|
|
|
* Stable 830gm/845g support, at last!
|
|
|
|
As usual we have a large number of bug fixes since the last release:
|
|
|
|
* Prevent a stray relocation being left after a buffer is removed from
|
|
a batch, leading to GPU hangs.
|
|
|
|
* Make the driver more robust against its own failures to submit batches
|
|
by falling back to software rendering.
|
|
|
|
* Fix emission of scanline waits for secondary pipes on gen6/7. Otherwise
|
|
you may encounter GPU hangs in MI_WAIT_FOR_EVENT.
|
|
|
|
* Fix a missing corner pixel when drawing rectangles with PolyLines
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=55484
|
|
|
|
* Don't try to use Y-tiling colour buffers with mesa/i915c as mesa
|
|
doesn't support them and wil fallback to software rendering
|
|
|
|
* Ensure that any cached mmaps are invalidated for a SwapBuffers
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=60042
|
|
|
|
* Correctly handle the composition of rotated displays too large for the
|
|
3D pipeline
|
|
https://bugs.freedesktop.org/show_bug.cgi?id=60124
|
|
|
|
* Fix the computation of the planar video frame size
|
|
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1104180
|
|
|
|
|
|
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 an 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.

|
|
============================
|
|
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.

|
|
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.
|

that the same flushes as required on gen5+ are also required for gen4.

prehistory tidying up the earlier generations which lay languishing as

|
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.
|
|

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.

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.
|
|
|
|

==============================
|
|
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.
|

|
|
==============================
|
|
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...
|
|
|

|
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.
|
|
|
|
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)

|
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

that this got fixed in time for the release!]

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)

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

|
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

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.
|
|
|
|

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:
|
|
|
|

---------
|
|
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

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
|
|
-------------------------------------------------
|
|
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:

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.

(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.
|
|
|
|
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.
|
|
|
|
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.
|
|
|
|
Snapshot 2.9.99.901 (2009-11-30)
|
|
================================
|
|
This is the first 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.
|
|
|
|
With this snapshot, the xf86-video-intel driver requires kernel
|
|
modesetting (KMS) as all of the user modesetting (UMS) support has
|
|
been removed from the driver.
|
|
|
|
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

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.
|
|
|
|
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.
|
|
|
|
