Tue Sep 9 14:00:00 2014 tobias.johannes.klausmannAATTmni.thm.de
- Update to 3.0 prerelease 2.99.916:
A Quick update for MST in UXA - we need to hook up the RandR outputs
for dynamicaly added connectors.

Tue Sep 9 14:00:00 2014 tobias.johannes.klausmannAATTmni.thm.de
- Update to 3.0 prerelease 2.99.915:
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=81886
https://bugs.freedesktop.org/show_bug.cgi?id=82273
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=82193
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).
https://bugs.freedesktop.org/show_bug.cgi?id=81973
- Remove upstreamed patch:
Patch1: U_Erase-cursor-image-when-changing-rotation.patch

- u_Erase-cursor-image-when-changing-rotation.patch
- > U_Erase-cursor-image-when-changing-rotation.patch

Fri Aug 29 14:00:00 2014 eichAATTsuse.com
- u_Erase-cursor-image-when-changing-rotation.patch
Erase cursor image when changing rotation:
The rotated cursor image will be at a different location
in the 64x64 bit block and won\'t overlap with the unrotated
image. Therefore it will not be overwritten if the real image
is smaller (bnc#893752).

Fri Aug 29 14:00:00 2014 eichAATTsuse.com
- u_sna_dri3_mesa_relies_upon_implicit_fences.patch
- > U_sna_dri3_mesa_relies_upon_implicit_fences.patch
Patches from upstream should be flagged with \'U\'.

Wed Jul 23 14:00:00 2014 tobias.johannes.klausmannAATTmni.thm.de
- Update to version 2.99.914:
A brown paper bag to hide the rebuilding from the tarball with
\'autoreconf -fi\' error that arose from not distributing the libobj/
directory.

Wed Jul 23 14:00:00 2014 tobias.johannes.klausmannAATTmni.thm.de
- Update to 3.0 prerelease 2.99.913: (Tarball from Git, Release Tarball is broken)
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
https://bugs.freedesktop.org/show_bug.cgi?id=80191
+ Fix framebuffer creation on kernels older than 3.11
Regression in 2.99.912
+ Check that the damage still exists after implicit reduction
Regression in 2.99.912
https://bugs.freedesktop.org/show_bug.cgi?id=77436
+ 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
https://bugs.freedesktop.org/show_bug.cgi?id=79992
+ Check clipping on PolyRect before discarding the clipped damage
Regression from 2.99.903
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.
- Remove upstream patches:
+ Patch1: U_sna_fix_scanout_creation_routine_for_old_kernels_3_11.patch
+ Patch2: U_sna-Clear-our-private-hints-about-front-rendering-ex.patch

Wed Jul 23 14:00:00 2014 tobias.johannes.klausmannAATTmni.thm.de

* sna: Clear our private hints about front rendering exported bo
(fdo#79999)

Wed Jun 11 14:00:00 2014 tobias.johannes.klausmannAATTmni.thm.de
- Add patch U_sna_fix_scanout_creation_routine_for_old_kernels_3_11.patch
Make this driver-version usable with kernel <= 3.11

Tue Jun 10 14:00:00 2014 sndirschAATTsuse.com
- Update to 3.0 prerelease 2.99.912:
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.

Wed Apr 2 14:00:00 2014 sndirschAATTsuse.com
- disable build of backlight-helper for now; just too much trouble
with policykit; and as long as there are GPUs considered supported
on our distribution without a proper KMS driver it\'s useless having
this anyway ...

Wed Mar 19 13:00:00 2014 tobias.johannes.klausmannAATTmni.thm.de
- Update to 3.0 prerelease 2.99.911:
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.
Regression from 2.99.903, but requires

- Add rpmlinrc file

Mon Feb 10 13:00:00 2014 sndirschAATTsuse.com
- Update to 3.0 prerelease 2.99.910

* 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).

Sat Feb 1 13:00:00 2014 tobias.johannes.klausmannAATTmni.thm.de
- Update to 3.0 prerelease 2.99.908:
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.
https://bugs.freedesktop.org/show_bug.cgi?id=73981
+ Fix rendering of dashed zero-width lines onto 24bit buffers
https://bugzilla.redhat.com/show_bug.cgi?id=1059152
+ Cap the freed Pixmap cache and reuse it more often
Fixes a regression in 2.99.907 that caused the memory used by X to
grow until it was cleaned up during server regreneration

- disable support for legacy User Mode Setting (for i810) on
!%ix86 systems, while other distros currently disable this feature
unconditionally, I am only suggesting this change for architectures
that do not or cannot have this hardware.

Mon Dec 30 13:00:00 2013 tobias.johannes.klausmannAATTmni.thm.de
- Update to 3.0 prerelease 2.99.907:
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!
+ Acceleration support for Intel\'s next generation of
integrated processor graphics has landed, codenamed Broadwell.
+ Fix potential X server infinite recursion (crash) from a gen2 bug fix
Regression in 2.99.906
https://bugs.freedesktop.org/show_bug.cgi?id=71605
+ Workaround a missing pipeline flush within Ivybridge, that would
leave black rectangles randomly over the output

+ Fix VSync on Haswell. (fdo#69119)
+ Disable Y-tiling on gen4 - (lp#1222203)
+ Disable same EDID detection based on property id - the kernel
likes to reuse ids leading to a failure to detect the right

to multiple connectors) to avoid upsetting Haswell and
leaving the screens blank
+ Honour the user preferrence for the initial mode, even if they

Wed Aug 21 14:00:00 2013 tobias.johannes.klausmannAATTmni.thm.de
- Update to version 2.21.15:
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.
- Packaging changes:
+ Remove xf86-video-intel-copyfb.diff (patch1)
Remove this old and long disabled patch. We shipped at least 12.3
wihout it!

Wed Aug 7 14:00:00 2013 tobias.johannes.klausmannAATTmni.thm.de
- Remove xf86-video-intel-dell_backlight.diff (patch0)

Sun Aug 4 14:00:00 2013 tobias.johannes.klausmannAATTmni.thm.de
- Update to version 2.21.14:
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.

Included in ths release

Sun Jul 28 14:00:00 2013 tobias.johannes.klausmannAATTmni.thm.de
- Update to version 2.21.13:
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.

Sun Jul 14 14:00:00 2013 tobias.johannes.klausmannAATTmni.thm.de
- Update to version 2.21.12:
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)

Mon Jul 1 14:00:00 2013 tobias.johannes.klausmannAATTmni.thm.de
- Update to version 2.21.11:
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

Sun Jun 23 14:00:00 2013 tobias.johannes.klausmannAATTmni.thm.de
- Update to version 2.21.10:
Fixes missing support for Xv (with the textured video adaptor) on

the regressions.
+ Restore vsync on textured videos. [regression from 2.21.8]
https://bugs.freedesktop.org/show_bug.cgi?id=65048
+ Fix incorrect ordering of possible_clones with certain outputs, which
can lead to attempting to incorrectly clone 2 outputs and failing to
light them up. [regression from 2.20.10]
+ Fix performance regression from not promoting large fills to the GPU
[regression from 2.21.7]
+ Undo the pixmap clone before performing a DRI2CopyRegion

Mon May 27 14:00:00 2013 tobias.johannes.klausmannAATTmni.thm.de
- Update to version 2.21.8:
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
https://bugs.freedesktop.org/show_bug.cgi?id=64841
+ Prevent potential NULL dereference of damage when checking COW support
+ Fix invalidation of clone after dirtying the pixmap via the CPU

Tue May 21 14:00:00 2013 tobias.johannes.klausmannAATTmni.thm.de
- Update to version 2.21.7:
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

+ 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.

Mon Apr 8 14:00:00 2013 tobias.johannes.klausmannAATTmni.thm.de
- Update to version 2.21.6:
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.

for muxed setups).
+ Fix the tests for AVX/AVX2 support in CPUID and remember to check for
OS support as well.

Sat Mar 23 13:00:00 2013 zaitorAATTopensuse.org
- Update to version 2.21.5:
+ 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
(fdo#62198).
+ Prevent Glamor from crashing if misconfigured.
+ Prevent UXA from crashing if torn down during PreInit.
+ Prevent miscompilation with different functional units having
different compiler flags. (fdo#62198)
+ Fix rendering of CompositeTriFan with recent Xorg.
+ Apply the video src-offset fix highlighted in the last release
(fdo#62343).
+ Fix rendering of multiple glyphs to very large destination
surfaces (lp#1156387).
+ Fix scanline waits for Haswell (lp#1156679).

+ Correct GPU limits for early gen2 and gen3 architectures and prevent
an infinite recursion for particular image sizes.

Thu Feb 21 13:00:00 2013 tobias.johannes.klausmannAATTmni.thm.de
- Update to version 2.21.3:
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.

Sun Feb 10 13:00:00 2013 tobias.johannes.klausmannAATTmni.thm.de
- Update to version 2.21.2:
Pass the brown paper bags, I need half a dozen or so. That seemingly
innocuous build fix with xorg-1.13 happned to have the little side-effect
of breaking glyph rendering with xorg-1.12 and older on 64-bit machines.

Sun Feb 10 13:00:00 2013 tobias.johannes.klausmannAATTmni.thm.de
- Update to version 2.21.1:
A fix for a potential GPU hang on 945gm (GMA3100) 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
+ Repair build against Xorg-1.6 and contemporary packages.

Fri Feb 1 13:00:00 2013 tobias.johannes.klausmannAATTmni.thm.de
- Update to version 2.21.0:
- A few new features:
+ Enable render acceleration for Haswell GT1/GT2.
+ Enable multi-threaded rasterisation of trapezoids and fallback composition
+ Utilile 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

+ Correctly handle the composition of rotated displays too large for the
3D pipeline

Mon Jan 21 13:00:00 2013 sndirschAATTsuse.com
- Update to version 2.20.19:
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.

Wed Jan 16 13:00:00 2013 tobias.johannes.klausmannAATTmni.thm.de
- Update to version 2.20.18:
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.
- Bugs fixed since 2.20.17:
+ 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.

Wed Dec 26 13:00:00 2012 tobias.johannes.klausmannAATTmni.thm.de
- Update to 2.20.17:
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.
- Bugs fixed since 2.20.16:
+ 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

Sun Dec 16 13:00:00 2012 tobias.johannes.klausmannAATTmni.thm.de
- Update to 2.20.16:
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!
- Bugs fixed since 2.20.15:
+ 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

And lo, enabling more of the common acceleration paths for gen4 revealed
another lurking bug - something is wrong with how we prepare Y-tiling

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

- Update to version 2.20.14:
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

Sat Oct 20 14:00:00 2012 tobias.johannes.klausmannAATTmni.thm.de
- Update to 2.20.12:
More bug reports, more bug fixes! Perhaps the headline feature is
that with 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+.
- Bugs fixed since 2.20.10:
+ 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.]

Sun Oct 14 14:00:00 2012 tobias.johannes.klausmannAATTmni.thm.de
- Update to version 2.20.10:
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.
- Bugs fixed since 2.20.9:
+ Release DRM master earlier during shutdown so switching between
multiple X servers works automatically.
https://bugs.freedesktop.org/show_bug.cgi?id=55446

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.

Sat Sep 29 14:00:00 2012 tobias.johannes.klausmannAATTmni.thm.de
- Update to version 2.20.9:
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.

+ Prepare for xorg-1.4, the api is being tweaked again.

Sun Sep 16 14:00:00 2012 tobias.johannes.klausmannAATTmni.thm.de
- Update to version 2.20.8:
+ Some bugs fixed, see below
+ Enabling ValleyView SDV
- Bugs fixed since 2.20.7:
+ 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 is being replaced.
This is most evident when combining software renders like Opera with
accelerated rendering.

Sat Sep 8 14:00:00 2012 tobias.johannes.klausmannAATTmni.thm.de
- Update to version 2.20.7:
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

Mon Sep 3 14:00:00 2012 tobias.johannes.klausmannAATTmni.thm.de
- Update to version 2.20.6:
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.
- Bugs fixed since 2.20.5:
+ 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
+ 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.

Mon Sep 3 14:00:00 2012 tobias.johannes.klausmannAATTmni.thm.de
- Update to version 2.20.5:
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

Sat Aug 18 14:00:00 2012 tobias.johannes.klausmannAATTmni.thm.de
- Update to version 2.20.4:
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.

Sat Aug 4 14:00:00 2012 tobias.johannes.klausmannAATTmni.thm.de
- Update to version 2.20.3:
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 performance
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.

Fri Jul 27 14:00:00 2012 tobias.johannes.klausmannAATTmni.thm.de
- Update to version 2.20.2:
+ FixedIvyBridge GT1 systems (HD2500 graphics) GPU hang
+ 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

Mon Jul 23 14:00:00 2012 tobias.johannes.klausmannAATTmni.thm.de
- Update to version 2.20.1:
- Restore DRI for i810
- Fixed the SNA fallbacks on 64 bit causing screen corruption
- Bug fixes:
+ 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.

Sun Jul 15 14:00:00 2012 tobias.johannes.klausmannAATTmni.thm.de
- Update to version 2.20.0:
- A new acceleration method \"sna\" that aims to be faster and
consume far less CPU than UXA is now available for selection at runtime.
- 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.

Tue Jun 12 14:00:00 2012 sndirschAATTsuse.com
- let require glamor package instead of recommending it, since the
driver is linked against this library (there is not only a glamor
Xserver module as I believed first!)

Fri Jun 1 14:00:00 2012 sndirschAATTsuse.com
- updated to latest git version 2.19.0_20120601_8eed569 with a lot
of fixes for SNA and the configuration possibility to use UXA,
SNA or GLAMOR 2D acceleration
- make again UXA the default, but als build SNA and GLAMOR backends
- recommend instead of require glamor package

Wed May 30 14:00:00 2012 sndirschAATTsuse.com
- apparently building with \"--disable-uxa --enable-glamor\" is
different from building with \"--enable-glamor\". The former
resulted in an intel driver no longer working at all. The latter
results in an \"glamor\"-enabled intel driver. So use the latter
one. ;-)

Wed May 30 14:00:00 2012 sndirschAATTsuse.com
