      1  1.1  mrg Snapshot 2.99.917 (2014-12-21)
      2  1.1  mrg ==============================
      3  1.1  mrg 3 months drifted by whilst I looked elsewhere for bugs.. The highlight of
      4  1.1  mrg bugs fixed here are a couple of workarounds required for Broadwell and
      5  1.1  mrg making sure that the rasterisation code is symmetric under inversions.
      6  1.1  mrg However, as a couple of crashers slipped through into 2.99.916 (though
      7  1.1  mrg not actual regressions in 2.99.916 per se) and 3 months have passed, we
      8  1.1  mrg should make one more snapshot before an imminent release.
      9  1.1  mrg 
     10  1.1  mrg  * Beware of recomputing the clear hint in the middle of MI recursion
     11  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=77074
     12  1.1  mrg 
     13  1.1  mrg  * Fix crash from rendering an empty Glyph string under PRIME as the
     14  1.1  mrg    secondary driver
     15  1.1  mrg 
     16  1.1  mrg  * Restore application of default monitor options to the first output,
     17  1.1  mrg    a regression in 2.99.915 and the MST support
     18  1.1  mrg    https://bugs.gentoo.org/show_bug.cgi?id=522500
     19  1.1  mrg 
     20  1.1  mrg  * Finally fix ZaphodHeads blocking on waiting for flip completion events.
     21  1.1  mrg    Before kernel 3.19, O_NONBLOCK support is broken and so we must avoid
     22  1.1  mrg    reading if we are not expecting an event.
     23  1.1  mrg 
     24  1.1  mrg  * Backwards compatibilty fix for fake triple buffering with PRIME and
     25  1.1  mrg    Xorg-1.15
     26  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=85144#c12
     27  1.1  mrg 
     28  1.1  mrg  * Fix a rendering issue with output rotation and software fallbacks.
     29  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=84653
     30  1.1  mrg 
     31  1.1  mrg  * Enable MST discovery even without udev support

     36  1.1  mrg 
     37  1.1  mrg  * Fix projective sampling on gen6+.
     38  1.1  mrg 
     39  1.1  mrg  * Fix rendering and corruption with gen8.
     40  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=84958
     41  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=83207

     48  1.1  mrg  * Fix rendering of right-to-left or bottom-to-top PolySegments in UXA
     49  1.1  mrg 
     50  1.1  mrg 
     51  1.1  mrg Snapshot 2.99.916 (2014-09-08)
     52  1.1  mrg ==============================
     53  1.1  mrg Quick update for MST in UXA - we need to hook up the RandR outputs for
     54  1.1  mrg dynamicaly added connectors.
     55  1.1  mrg 
     56  1.1  mrg 
     57  1.1  mrg Snapshot 2.99.915 (2014-09-08)
     58  1.1  mrg ==============================
     59  1.1  mrg A significant change to UXA to enable MST and to keep it working on recent
     60  1.1  mrg kernels needs some soaking before a major release, and the usual
     61  1.1  mrg plethora of bugfixes. One other feature is the support for hardware
     62  1.1  mrg rotations on very recent kernels.
     63  1.1  mrg 
     64  1.1  mrg  * Handle rotated scanouts that are all clear correctly. The region to
     65  1.1  mrg    update was not being computed correctly, overdrawing the wrong CRTC.
     66  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=81820
     67  1.1  mrg 
     68  1.1  mrg  * Reset cursor images after rotation and size changes
     69  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=81886
     70  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=82273
     71  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=82337
     72  1.1  mrg 
     73  1.1  mrg  * Handle stale DRI2 buffers and Client errors more gracefully
     74  1.1  mrg 
     75  1.1  mrg  * Fallback if we fail to render a glyph onto a too-large surface, e.g.
     76  1.1  mrg    direct rendering of glyphs onto extended desktops with gen2/gen3.
     77  1.1  mrg    https://bugs.archlinux.org/task/40949
     78  1.1  mrg 
     79  1.1  mrg  * Further work to enable tiled rendering onto large surfaces in
     80  1.1  mrg    severely aperture and memory constrained devices (e.g. gen2/gen3)
     81  1.1  mrg 
     82  1.1  mrg  * Honour the Primary option from xorg.conf and mark that as the RandR
     83  1.1  mrg    primary.
     84  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=82193
     85  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=82205
     86  1.1  mrg 
     87  1.1  mrg  * Fix another Client-Window DRI2 close race
     88  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=82979
     89  1.1  mrg 
     90  1.1  mrg  * Fix incorrect discarding of GPU damage when copying over the TearFree
     91  1.1  mrg    scanout - which caused a flicker in rapidly updated elements (like
     92  1.1  mrg    simple video panes).
     93  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=81973
     94  1.1  mrg 
     95  1.1  mrg 
     96  1.1  mrg Snapshot 2.99.914 (2014-07-23)
     97  1.1  mrg ==============================
     98  1.1  mrg And a brown paper bag to hide the rebuilding from the tarball with
     99  1.1  mrg 'autoreconf -fi' error that arose from not distributing the libobj/
    100  1.1  mrg directory.
    101  1.1  mrg 
    102  1.1  mrg 
    103  1.1  mrg Snapshot 2.99.913 (2014-07-23)
    104  1.1  mrg ==============================
    105  1.1  mrg This should be it... A few fixes from testing the new code, we should be
    106  1.1  mrg ready for the final release. However, we do have one standout feature in
    107  1.1  mrg this snapshot, we now officially recognise HD Graphics 5300/5500/5600,
    108  1.1  mrg Iris Graphics 6100 and Iris Pro Graphics 6200/P6300 (formerly known as
    109  1.1  mrg Broadwell).
    110  1.1  mrg 
    111  1.1  mrg  * Check the window actually covers the CRTC before doing a single CRTC flip,
    112  1.1  mrg    and then restore the right framebuffer after completing CRTC flips.
    113  1.1  mrg    Otherwise we would detect an error and disable an output under TearFree
    114  1.1  mrg    Regression in 2.99.912
    115  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=80191
    116  1.1  mrg 
    117  1.1  mrg  * Fix framebuffer creation on kernels older than 3.11
    118  1.1  mrg    Regression in 2.99.912
    119  1.1  mrg 
    120  1.1  mrg  * Check that the damage still exists after implicit reduction
    121  1.1  mrg    Regression in 2.99.912
    122  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=77436
    123  1.1  mrg 
    124  1.1  mrg  * Fix direction flags for fallback composited CopyAreas which
    125  1.1  mrg    caused scrolling corruption in a few configurations
    126  1.1  mrg    Regression from 2.20.0
    127  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=79843
    128  1.1  mrg 
    129  1.1  mrg  * Do not throw away damage if there is no redundant copy
    130  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=79992
    131  1.1  mrg 
    132  1.1  mrg  * Check clipping on PolyRect before discarding the clipped damage
    133  1.1  mrg    Regression from 2.99.903
    134  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=79992
    135  1.1  mrg 
    136  1.1  mrg  * Fix hints for GLXPixmapa, as these are never swapped and so
    137  1.1  mrg    miss invalidating the hints on SwapBuffers with the result
    138  1.1  mrg    that they are often presumed blank
    139  1.1  mrg    Regression in 2.99.912
    140  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=79999
    141  1.1  mrg 
    142  1.1  mrg  * Fix incoherent choice of source bo when constructing 8x8 tiles,
    143  1.1  mrg    incorrect pattern origin when extracting, and then fix the
    144  1.1  mrg    alignment of colour patterns for BLT operations
    145  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=80033
    146  1.1  mrg 
    147  1.1  mrg  * Disable blending with the render engine on snoopable buffers
    148  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=80253
    149  1.1  mrg 
    150  1.1  mrg  * Restore throttling to prevent client lag under heavy GPU load
    151  1.1  mrg    Regression from 2.21.10
    152  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=77436
    153  1.1  mrg 
    154  1.1  mrg  * Use ClientGone for notifications on shared DRI2 windows to prevent
    155  1.1  mrg    rare crashes due to use-after-free of the swap requests
    156  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=80157
    157  1.1  mrg 
    158  1.1  mrg  * Ensure the mmaped CPU bo is idle before migrating damage
    159  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=80560
    160  1.1  mrg 
    161  1.1  mrg  * Fix incorrect clipping by the render engine for large DRI2 windows
    162  1.1  mrg 
    163  1.1  mrg  * Ensure that the aperture tiling fallbacks are bounded
    164  1.1  mrg 
    165  1.1  mrg  * Validate parameter to xf86-video-intel-backlight-helper more carefully
    166  1.1  mrg    (CVE-2014-4910)
    167  1.1  mrg 
    168  1.1  mrg  * Fix slaved scanouts for reverse optimus, though rotated slaves will
    169  1.1  mrg    require further patches to Xorg.
    170  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=81383
    171  1.1  mrg 
    172  1.1  mrg  * Fix build without Composite extension.
    173  1.1  mrg 
    174  1.1  mrg  * Fix build without gettline().
    175  1.1  mrg 
    176  1.1  mrg  * UXA: Allocate and resize frontbuffer consistently to pass sanity checks
    177  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=80088
    178  1.1  mrg 
    179  1.1  mrg  * UXA: Report cached backlight value when the output is off (like sna)
    180  1.1  mrg    https://bugzilla.redhat.com/show_bug.cgi?id=1032978
    181  1.1  mrg 
    182  1.1  mrg  * UXA: Mark outputs as off before the kernel does (like sna)
    183  1.1  mrg    This will prevent the internal panel from starting up blank in some
    184  1.1  mrg    multi-monitor configurations
    185  1.1  mrg    https://bugzilla.redhat.com/show_bug.cgi?id=1103806
    186  1.1  mrg 
    187  1.1  mrg Note that the DRI2 exchange mechanism introduced in 2.99.912 exposes bugs
    188  1.1  mrg in some compositors, at least kwin and comptom, which discard DRI2 buffer
    189  1.1  mrg invalidates rather than resourcing their texture. For example,
    190  1.1  mrg https://bugs.kde.org/show_bug.cgi?id=336589
    191  1.1  mrg 
    192  1.1  mrg Note that the improved triple buffering introduced in DRI2 requires a patch
    193  1.1  mrg to Xorg (now released upstream) to prevent crashes with DRI_PRIME.
    194  1.1  mrg https://bugs.freedesktop.org/show_bug.cgi?id=80001
    195  1.1  mrg 
    196  1.1  mrg Note that DRI3/Present require tracking the relevant development trees for
    197  1.1  mrg mesa and the xserver as they are very much still under early testing. Also
    198  1.1  mrg be aware that Mesa provides no support for explicit fencing so Damage
    199  1.1  mrg tracking between compositors and clients is unserialised.
    200  1.1  mrg 
    201  1.1  mrg 
    202  1.1  mrg Snapshot 2.99.912 (2014-06-10)
    203  1.1  mrg ==============================
    204  1.1  mrg A final round of features. We have everything from support for variable
    205  1.1  mrg cursor sizes, support for the DRI3 and Present extensions, improved DRI2
    206  1.1  mrg support, support for Xserver 1.16, userptr from kernel 3.16, and
    207  1.1  mrg precursory support for DP multistream transport,
    208  1.1  mrg 
    209  1.1  mrg  * Avoid discarding dirty pixels when promoting a migration to cover the
    210  1.1  mrg    whole pixmap.
    211  1.1  mrg    Regression in 2.99.911
    212  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=77063
    213  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=77178
    214  1.1  mrg 
    215  1.1  mrg  * Avoid overextending degenerate lines (and consequentially accessing
    216  1.1  mrg    pixels outside of our damaged area).
    217  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=77074
    218  1.1  mrg 
    219  1.1  mrg  * Fix subpixel glyph rendering on gen2 devices (830-865 chipsets)
    220  1.1  mrg    Regression in 2.99.911
    221  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=77201
    222  1.1  mrg 
    223  1.1  mrg  * Share the global pixman glyph cache between ZaphodHeads
    224  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=54707
    225  1.1  mrg 
    226  1.1  mrg  * Light up all connected outputs, even if their status is unknown, on
    227  1.1  mrg    takeover from fbcon. This prevents loss of display after a resume
    228  1.1  mrg    on recent kernels, for example.
    229  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=77768
    230  1.1  mrg 
    231  1.1  mrg  * Show the video overlay (when supported by the hardware) across all
    232  1.1  mrg    outputs.
    233  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=77802
    234  1.1  mrg 
    235  1.1  mrg  * Do not discard damage when performing "BLT" spans inplace with the CPU.
    236  1.1  mrg    Regression from 2.20.10
    237  1.1  mrg 
    238  1.1  mrg  * Avoid discarding IO buffers too early during their preparation for a
    239  1.1  mrg    new batch
    240  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=79238
    241  1.1  mrg 
    242  1.1  mrg  * Fix fallback handling for displaying large scaled framebuffers (that
    243  1.1  mrg    are too large to be scaled by the GPU in a single pass)
    244  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=79320
    245  1.1  mrg 
    246  1.1  mrg  * Listen to external modifications of backlight value and propagate
    247  1.1  mrg    the notifications to RandR clients. This should make the GUI report
    248  1.1  mrg    ACPI keypresses to change the backlight correctly.
    249  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=79699
    250  1.1  mrg 
    251  1.1  mrg  * UXA: fix pageflips with 3 heads.
    252  1.1  mrg 
    253  1.1  mrg  * UXA: do not report a BadMatch error for DRI2GetMsc - as clients are
    254  1.1  mrg    often unprepared and die when they get the unexpected error.
    255  1.1  mrg 
    256  1.1  mrg 
    257  1.1  mrg Snapshot 2.99.911 (2014-03-19)
    258  1.1  mrg ==============================
    259  1.1  mrg Hans de Geode has been working on making the Xserver work without
    260  1.1  mrg privileges under the supervision of systemd/logind. This necessitated a
    261  1.1  mrg few new features for us: server fds (where we are passed which fd to use
    262  1.1  mrg to talk to our device by the Xserver who may in turn receive it from
    263  1.1  mrg logind or other host) and a small backlight helper so that we can continue
    264  1.1  mrg to provide a RandR backlight property when running without root privileges.
    265  1.1  mrg 
    266  1.1  mrg  * Flush when changing blend modes on Ironlake, or else single glyphs
    267  1.1  mrg    are sometimes rendered incorrectly
    268  1.1  mrg    Regression from 2.20.15
    269  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=74882
    270  1.1  mrg 
    271  1.1  mrg  * Fix pixmap offsets for pixman fallbacks onto Composite redirected
    272  1.1  mrg    windows
    273  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=73811
    274  1.1  mrg 
    275  1.1  mrg  * Fix blending onto 8-bit destinations, typically used for generating
    276  1.1  mrg    masks in complex Render operations, on gen2
    277  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=75818
    278  1.1  mrg 
    279  1.1  mrg  * Handle failure to create DRI bo more carefully. For example on gen3,
    280  1.1  mrg    the DDX supports pixmaps that are much, much larger than OpenGL can
    281  1.1  mrg    use and do not support the tiling modes that we request for OpenGL.
    282  1.1  mrg    https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1289049
    283  1.1  mrg 
    284  1.1  mrg  * Fix a bookkeeping bug with proxy buffers that are marked active but
    285  1.1  mrg    not actually inserted into a request (so they end up permanently
    286  1.1  mrg    active and confuse everybody).
    287  1.1  mrg    https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1289923
    288  1.1  mrg 
    289  1.1  mrg  * Actually turn off displays with DPMS off for UXA.
    290  1.1  mrg    Regression from 2.99.903, but requires
    291  1.1  mrg

    295  1.1  mrg 
    296  1.1  mrg        drm/i915: Only apply DPMS to the encoder if enabled
    297  1.1  mrg 
    298  1.1  mrg    instead for correct behaviour on Haswell.

    301  1.1  mrg 
    302  1.1  mrg Snapshot 2.99.910 (2014-02-10)
    303  1.1  mrg ==============================
    304  1.1  mrg Another latent bug exposed by recent changes merit another snapshot for
    305  1.1  mrg final testing.
    306  1.1  mrg 
    307  1.1  mrg   * Only discard damage when overwriting the dirty CPU bo, instead
    308  1.1  mrg     of discarding damage that will be shown!
    309  1.1  mrg 
    310  1.1  mrg   * Reset operation state when switching between glyph caches.
    311  1.1  mrg     https://bugs.freedesktop.org/show_bug.cgi?id=74494
    312  1.1  mrg 
    313  1.1  mrg   * Fully reinitialise pixmaps allocated from the freed cache. Fixes
    314  1.1  mrg     a potential issue (crash or misrendering) when using some compositors.
    315  1.1  mrg     https://bugs.freedesktop.org/show_bug.cgi?id=74550
    316  1.1  mrg 
    317  1.1  mrg   * Do not expose the TexturedVideo adaptor in UXA when it is disabled
    318  1.1  mrg     either due to a hung GPU or explicitly disabled by the user.
    319  1.1  mrg 
    320  1.1  mrg   * Restore the pipe stall when changing CC state on gen6, otherwise
    321  1.1  mrg     the GPU may not flush intermediate results from all EU resulting
    322  1.1  mrg     in render corruption (usually the occasional black box).
    323  1.1  mrg     Regression from 2.99.906
    324  1.1  mrg     https://bugs.freedesktop.org/show_bug.cgi?id=7237
    325  1.1  mrg 
    326  1.1  mrg 
    327  1.1  mrg Snapshot 2.99.909 (2014-02-01)
    328  1.1  mrg ==============================
    329  1.1  mrg Pass the brown paper bag. Ridiculously stupid bug in last minute coding.
    330  1.1  mrg 
    331  1.1  mrg   * Add Xv support using glamor acceleration in addition to adaptors
    332  1.1  mrg     provided by the UXA backend.
    333  1.1  mrg 
    334  1.1  mrg   * Fix overeager discarding of CPU damage
    335  1.1  mrg     Regression in 2.99.908 :(
    336  1.1  mrg     https://bugs.freedesktop.org/show_bug.cgi?id=74327
    337  1.1  mrg 
    338  1.1  mrg 
    339  1.1  mrg Snapshot 2.99.908 (2014-01-31)
    340  1.1  mrg ==============================
    341  1.1  mrg A couple of regressions dashed the hopes that .907 was to be the final
    342  1.1  mrg release candidate, so time to start the cycle again after applying a few
    343  1.1  mrg more bugfixes.
    344  1.1  mrg 
    345  1.1  mrg   * Fix invalid pageflipping of GLXPixmaps by UXA.
    346  1.1  mrg     https://bugs.freedesktop.org/show_bug.cgi?id=73282
    347  1.1  mrg 
    348  1.1  mrg   * Consistently treat DPMS Suspend/Standy as Off, otherwise we may
    349  1.1  mrg     incorrectly restore the backlight in UXA.
    350  1.1  mrg 
    351  1.1  mrg   * Fix disabling the backlight in UXA when querying the value whilst off
    352  1.1  mrg     https://bugs.freedesktop.org/show_bug.cgi?id=73181.
    353  1.1  mrg 
    354  1.1  mrg   * Invalidate between every operation if rendering into the source or mask.
    355  1.1  mrg     Fixes regression in 2.99.907 on Ivybridge (seen in KDE)
    356  1.1  mrg     https://bugs.freedesktop.org/show_bug.cgi?id=73208
    357  1.1  mrg 
    358  1.1  mrg   * Check for available batch buffer state before restoring state on gen4,
    359  1.1  mrg     otherwise we overwrite surface state with commands and cause a GPU hang.
    360  1.1  mrg     https://bugs.freedesktop.org/show_bug.cgi?id=73348
    361  1.1  mrg 
    362  1.1  mrg   * Prevent an invalid free by TearFree
    363  1.1  mrg     https://bugs.freedesktop.org/show_bug.cgi?id=73469
    364  1.1  mrg 
    365  1.1  mrg   * Fix confusion in TearFree when it tried to pageflip to a stale bo
    366  1.1  mrg     https://bugs.freedesktop.org/show_bug.cgi?id=70905
    367  1.1  mrg 
    368  1.1  mrg   * Initialise TearFree contents with the current frontbuffer upon creation,
    369  1.1  mrg     otherwise old content may be visible for significant fractions of a
    370  1.1  mrg     second after resume or DPMS on
    371  1.1  mrg     https://bugs.freedesktop.org/show_bug.cgi?id=73842
    372  1.1  mrg 
    373  1.1  mrg   * Nullify the old pointer into a CPU mmapping of the bo when promoting it
    374  1.1  mrg     on the GPU. Eventually that old pointer becomes invalid and will cause
    375  1.1  mrg     the Xserver to crash.
    376  1.1  mrg     Fixes regression in 2.99.906
    377  1.1  mrg     https://bugs.freedesktop.org/show_bug.cgi?id=73351
    378  1.1  mrg 
    379  1.1  mrg   * Restore the serialNumber on the GC correctly after falling back to
    380  1.1  mrg     software. This was seen to cause corruption with Wine.
    381  1.1  mrg     https://bugs.freedesktop.org/show_bug.cgi?id=73856
    382  1.1  mrg 
    383  1.1  mrg   * Do not ignore CPU damage on a pixmap unless the Composite operation
    384  1.1  mrg     will completely overwrite it. This was observed in xfce4.
    385  1.1  mrg     https://bugs.freedesktop.org/show_bug.cgi?id=69528
    386  1.1  mrg 
    387  1.1  mrg   * Skip fake outputs during initial probe as they can cause a NULL pointer
    388  1.1  mrg     dereference.
    389  1.1  mrg     https://bugs.freedesktop.org/show_bug.cgi?id=73981
    390  1.1  mrg 
    391  1.1  mrg   * Fix rendering of dashed zero-width lines onto 24bit buffers
    392  1.1  mrg     https://bugzilla.redhat.com/show_bug.cgi?id=1059152
    393  1.1  mrg 
    394  1.1  mrg   * Cap the freed Pixmap cache and reuse it more often
    395  1.1  mrg     Fixes a regression in 2.99.907 that caused the memory used by X to
    396  1.1  mrg     grow until it was cleaned up during server regreneration
    397  1.1  mrg     https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1272338

    399  1.1  mrg 
    400  1.1  mrg Snapshot 2.99.907 (2013-12-30)
    401  1.1  mrg ==============================
    402  1.1  mrg The highlight here is that things seem to be quietening down on the bug
    403  1.1  mrg reporting front. All is not quiet as you will see below, and maybe it is
    404  1.1  mrg just the holiday season that is approaching*, but there has been a
    405  1.1  mrg remarkable falloff in bug reports. Lets hope this trend holds and we can
    406  1.1  mrg make a stable release shortly!
    407  1.1  mrg 
    408  1.1  mrg * This was intended to be sent a couple of weeks ago and the holiday season
    409  1.1  mrg has been very quiet....
    410  1.1  mrg 
    411  1.1  mrg Oh, and acceleration support for Intel's next generation of
    412  1.1  mrg integrated processor graphics has landed, codenamed Broadwell.
    413  1.1  mrg 
    414  1.1  mrg  * Fix potential X server infinite recursion (crash) from a gen2 bug fix
    415  1.1  mrg    Regression in 2.99.906
    416  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=71605
    417  1.1  mrg 
    418  1.1  mrg  * Workaround a missing pipeline flush within Ivybridge, that would
    419  1.1  mrg    leave black rectangles randomly over the output
    420  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=68410
    421  1.1  mrg 
    422  1.1  mrg  * Fix tiled fills. gen2-3 and gen4+ had two different bugs that
    423  1.1  mrg    both broke rendering with small 8x8 patterns in some circumstances
    424  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=71260
    425  1.1  mrg 
    426  1.1  mrg  * Fix reads from a cropped video image using a packed pixel format.
    427  1.1  mrg 
    428  1.1  mrg  * Another clear the clear hint after DRI2 SwapBuffers, like the bug fixed
    429  1.1  mrg    in 2.99.903. Failure to clear the hint would cause read backs of the
    430  1.1  mrg    frontbuffer (Xvnc) to be blank.
    431  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=72194
    432  1.1  mrg 
    433  1.1  mrg  * Disable VSync on Baytrail

    438  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=72430
    439  1.1  mrg 
    440  1.1  mrg  * Avoid recusing through DRI event handlers whilst processing TearFree,
    441  1.1  mrg    leading to a double free (and memory corruption)
    442  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=72690
    443  1.1  mrg 
    444  1.1  mrg  * Hide the gen4 render corruption by crippling the GPU
    445  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=55500
    446  1.1  mrg 
    447  1.1  mrg 
    448  1.1  mrg Snapshot 2.99.906 (2013-11-13)
    449  1.1  mrg ==============================
    450  1.1  mrg Several stability fixes required after the recent tweaking of the core
    451  1.1  mrg mechanics to handle the updated TearFree and attempting to make static
    452  1.1  mrg analyzers happy.
    453  1.1  mrg 
    454  1.1  mrg  * Fix damage handling when rendering to a partially damaged GPU surface.
    455  1.1  mrg    Regression in 2.99.905

    459  1.1  mrg    Regression in 2.99.905
    460  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=70835
    461  1.1  mrg 
    462  1.1  mrg  * Improve accounting for fence overallocation on older gen2/3, and
    463  1.1  mrg    improve the tiling mechanism to fit into the same aperture constraints
    464  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=70924

    473  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=71415
    474  1.1  mrg 
    475  1.1  mrg  * Fix various fail along the memcpy_xor paths, including inadequate error
    476  1.1  mrg    handling and integer overflow
    477  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=70527
    478  1.1  mrg 
    479  1.1  mrg  * Fix outside-of-target stipple uploads

    489  1.1  mrg 
    490  1.1  mrg Snapshot 2.99.905 (2013-10-23)
    491  1.1  mrg ==============================
    492  1.1  mrg The highlight for this snapshot is the extension of TearFree to support
    493  1.1  mrg transformed outputs, along with some polishing to eliminate its impact
    494  1.1  mrg upon input and output latency. As always, thanks to everyone who have
    495  1.1  mrg been testing, reporting bugs and helping to improve the stability before
    496  1.1  mrg release.
    497  1.1  mrg 
    498  1.1  mrg  * Prevent a crash when starting with a user specified mode or position

    519  1.1  mrg Snapshot 2.99.904 (2013-10-09)
    520  1.1  mrg ==============================
    521  1.1  mrg There is one more feature planned to be completed for 3.0, so time for a
    522  1.1  mrg snapshot beforehand to push out the bug fixes from the last week.
    523  1.1  mrg 
    524  1.1  mrg  * Fix video output using sprites when changing the image size
    525  1.1  mrg 
    526  1.1  mrg  * Apply more restrictive tile constaints for 915g class devices
    527  1.1  mrg    https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1232546
    528  1.1  mrg 
    529  1.1  mrg  * Ensure all overlapping rectangles are drawn for XRenderFillRectangles
    530  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=66313
    531  1.1  mrg 
    532  1.1  mrg  * Fix trapezoid clipping against the left-edge
    533  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=69469
    534  1.1  mrg 
    535  1.1  mrg  * Prevent discarding active upload buffers, causing glitches in chromium
    536  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=66990
    537  1.1  mrg 
    538  1.1  mrg  * Prevent specifying a negative timeout to select if the BlockHandler
    539  1.1  mrg    takes too long to update the display
    540  1.1  mrg 
    541  1.1  mrg  * Promote the Ironlake pipecontrol to be a full pipeline flush to
    542  1.1  mrg    prevent render cache corruption
    543  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=51422
    544  1.1  mrg 
    545  1.1  mrg  * Never pass an invalid trapezoid to pixman
    546  1.1  mrg    https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1197921

    554  1.1  mrg  * Build fixes for 1.14.99.2
    555  1.1  mrg 
    556  1.1  mrg 
    557  1.1  mrg Snapshot 2.99.903 (2013-09-28)
    558  1.1  mrg ==============================
    559  1.1  mrg Lots more stabilization work, not yet peaceful enough to christen 3.0. We
    560  1.1  mrg have everything ranging from build fixes for systems like Suse Linux
    561  1.1  mrg Enterprise Desktop that like to backport hardware enablement to ancient
    562  1.1  mrg packages, to fixes for hardware enabling, and some more performance tuning.
    563  1.1  mrg 
    564  1.1  mrg  * Fix VSync on Haswell.
    565  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=69119
    566  1.1  mrg 
    567  1.1  mrg  * Disable Y-tiling on gen4 - it too frequently leads to instability.
    568  1.1  mrg    https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1222203
    569  1.1  mrg 
    570  1.1  mrg  * Disable same EDID detection based on property id - the kernel likes
    571  1.1  mrg    to reuse ids leading to a failure to detect the right modes on a monitor
    572  1.1  mrg    change.
    573  1.1  mrg 
    574  1.1  mrg  * Avoid issuing multiple DPMS requests to the same encoder (alised to
    575  1.1  mrg    multiple connectors) to avoid upsetting Haswell and leaving the
    576  1.1  mrg    screens blank.
    577  1.1  mrg 
    578  1.1  mrg  * Honour the user preferrence for the initial mode, even if they are
    579  1.1  mrg    being silly
    580  1.1  mrg    https://bugzilla.novell.com/show_bug.cgi?id=841696
    581  1.1  mrg 
    582  1.1  mrg  * Clear the clear hint when apply DRI updates - to prevent some
    583  1.1  mrg    screenshots from GL windows being left blank.
    584  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=69730
    585  1.1  mrg 
    586  1.1  mrg  * Prevent a NULL dereference from trying to undo an non-existent buffer

    588  1.1  mrg 
    589  1.1  mrg  * Handle out-of-memory conditions far more gracefully. If the system is
    590  1.1  mrg    hard against the memory wall, then the kernel will start issuing
    591  1.1  mrg    SIGBUS even for CPU mmaps. Untrapped these will cause X to die.

    595  1.1  mrg Snapshot 2.99.902 (2013-09-07)
    596  1.1  mrg ==============================
    597  1.1  mrg We do not condone or support Canonical in the course of action they have
    598  1.1  mrg chosen, and will not carry XMir patches upstream.

    600  1.1  mrg 
    601  1.1  mrg Snapshot 2.99.901 (2013-09-04)
    602  1.1  mrg ==============================
    603  1.1  mrg What's this? A pre-release snapshot of an upcoming 3.0 major release?
    604  1.1  mrg What could be the big new feature about to land? SNA by default!
    605  1.1  mrg Not only that, we also have a preview of the XMir integration patches.
    606  1.1  mrg 
    607  1.1  mrg Whilst we consider the SNA acceleration method to be ready to take over
    608  1.1  mrg from UXA (the current acceleration method), it still remains possible to
    609  1.1  mrg switch over to the old method with the following xorg.conf snippet:
    610  1.1  mrg   Section "Device"
    611  1.1  mrg     Identifier "Device0"
    612  1.1  mrg     Driver "intel"
    613  1.1  mrg     Option "AccelMethod" "UXA"
    614  1.1  mrg   EndSection
    615  1.1  mrg 
    616  1.1  mrg The promise of SNA is that it improves the user experience by providing a
    617  1.1  mrg faster, more fluid, desktop, that is both more power efficient and less
    618  1.1  mrg prone to crashes than UXA. If it still fails to meet your expections,
    619  1.1  mrg please file bugs!

    622  1.1  mrg Release 2.21.15 (2013-08-21)
    623  1.1  mrg ============================
    624  1.1  mrg Some build fixes for the BSDs and alternate compiler, and conflicting
    625  1.1  mrg configure options and a critcial fix for some PRIME setups.
    626  1.1  mrg 
    627  1.1  mrg  * Don't fail to configure if DRI1 is not available and the user asks
    628  1.1  mrg    for both DRI and KMS-only
    629  1.1  mrg    [Regression from 2.21.14]
    630  1.1  mrg 
    631  1.1  mrg  * Lots of miscellaneous fixes for older gcc, other compilers and BSD.
    632  1.1  mrg 
    633  1.1  mrg  * Initial framework support for hosted X.
    634  1.1  mrg 
    635  1.1  mrg  * Improve transition from fbcon to X with multiple outputs and extended
    636  1.1  mrg    desktops.
    637  1.1  mrg 
    638  1.1  mrg  * Ensure the framebuffer exists before checking it against the CRTC
    639  1.1  mrg    constraints.
    640  1.1  mrg    https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/121234
    641  1.1  mrg    [Regression from 2.21.10]
    642  1.1  mrg 
    643  1.1  mrg  * Add RGB overlay support for Ironlake and later.
    644  1.1  mrg 
    645  1.1  mrg  * Don't release the overlay buffer too early, i.e. before the client
    646  1.1  mrg    disables the Xv image.
    647  1.1  mrg 
    648  1.1  mrg  * Tweak the ring switching logic to reduce use of semaphores on
    649  1.1  mrg    Sandybridge and later - a delicate balancing act between trying to
    650  1.1  mrg    use the faster engine for the task and preventing concurrent use of
    651  1.1  mrg    multiple rings.
    652  1.1  mrg 
    653  1.1  mrg 
    654  1.1  mrg Release 2.21.14 (2013-08-04)
    655  1.1  mrg ============================
    656  1.1  mrg A few updates for the top-end Haswell systems (notably GT3 and GT3e
    657  1.1  mrg systems), in particular, setting the appropriate thread counts for the
    658  1.1  mrg larger GPU and handling a few scaling issues with the emedded DRAM. More
    659  1.1  mrg important than the performance tuning though is a fix for a critical
    660  1.1  mrg issue encountered by a few people on gen4/gen5 systems.
    661  1.1  mrg 
    662  1.1  mrg  * Initial performance tuning for HSW:GT3e
    663  1.1  mrg 
    664  1.1  mrg  * Fix a crash with Planetary Annihilation
    665  1.1  mrg 
    666  1.1  mrg  * Disable triple buffering for compositors
    667  1.1  mrg 
    668  1.1  mrg  * Reserve space in the exec buffer array for deferred VBOs.

    670  1.1  mrg 
    671  1.1  mrg 
    672  1.1  mrg Release 2.21.13 (2013-07-27)
    673  1.1  mrg ============================
    674  1.1  mrg A minor release to repair the build for non-Linux systems, and to undo a
    675  1.1  mrg few more regressions.
    676  1.1  mrg 
    677  1.1  mrg  * Avoid potential memory corruption with allocations of very small
    678  1.1  mrg    depth 1 bitmaps.
    679  1.1  mrg 
    680  1.1  mrg  * Fix source clipping whilst computing copy extents and exposures.

    682  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=66970
    683  1.1  mrg 
    684  1.1  mrg  * Use /proc/cpuinfo if cpuid4 is not available (old hardware or old
    685  1.1  mrg    gcc), and repair the build on systems without cpuid.
    686  1.1  mrg    [Regression from 2.21.12]
    687  1.1  mrg 
    688  1.1  mrg  * Fix performance regression on Ironlake from inadvertently flushing
    689  1.1  mrg    after every operation.
    690  1.1  mrg    [Regression from 2.21.11]
    691  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=67157
    692  1.1  mrg 
    693  1.1  mrg  * Fix conflict handling when probing initial KMS configuration for
    694  1.1  mrg    ZaphodHeads.
    695  1.1  mrg    [Regression from 2.21.11]
    696  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=67176
    697  1.1  mrg 
    698  1.1  mrg  * Stop being overly restrictive and rejecting stale DRI2 buffers.
    699  1.1  mrg    (DRI2 is inherently racy in that the client may have completed and
    700  1.1  mrg    submitted rendering to buffers that are now invalid on the server.
    701  1.1  mrg    This race is magnified by bugs within the Xserver where it forgets
    702  1.1  mrg    to notify the DRI2 clients of certain invalidation events.)
    703  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=67210
    704  1.1  mrg 
    705  1.1  mrg  * Handle a failure to use a GTT mmap for a pixmap upload and try
    706  1.1  mrg    an alternative method before giving up.
    707  1.1  mrg 
    708  1.1  mrg 
    709  1.1  mrg Release 2.21.12 (2013-07-14)
    710  1.1  mrg ============================
    711  1.1  mrg In this release, we clear up the teething troubles from preserving the KMS
    712  1.1  mrg configuration, notably external connections on Haswell and plugging in new
    713  1.1  mrg outputs after startup were broken. Besides these regression fixes, there
    714  1.1  mrg are a couple of fixes for some long standing issues, such as incorrect
    715  1.1  mrg rendering on gen2, an infinite loop with very, very large pixmaps and a
    716  1.1  mrg slight improvement to the tempermental gen4.
    717  1.1  mrg 
    718  1.1  mrg  * Allow untiled scanouts again (required for large extended desktops on
    719  1.1  mrg    gen2 and gen3).
    720  1.1  mrg    [Regression from 2.21.11]
    721  1.1  mrg 
    722  1.1  mrg  * Use the correct count of the number of dirty damage boxes for the quick
    723  1.1  mrg    check on whether the existing damage contains the requested area.
    724  1.1  mrg    The danger is that we may get a false result and skip migration and so
    725  1.1  mrg    cause pixmap corruption (in the unlikely event that the application
    726  1.1  mrg    frequently causes fallbacks).
    727  1.1  mrg    [Regression from 2.21.11]
    728  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=66430
    729  1.1  mrg 
    730  1.1  mrg  * Fix initial connection probing for multi-function encoders, such as the
    731  1.1  mrg    external connections on Haswell.
    732  1.1  mrg    [Regression from 2.21.11, initial connection probing]
    733  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=66488
    734  1.1  mrg 
    735  1.1  mrg  * Fix gen2 rendercopy into a8 surfaces, for example, glyph uploads into
    736  1.1  mrg    the glyph cache.
    737  1.1  mrg 
    738  1.1  mrg  * Fix detection of user overrides for initial connection configuration.
    739  1.1  mrg    The code used the xorg-server-1.15 values, having missed the
    740  1.1  mrg    introduction of ZoomModes into that release.
    741  1.1  mrg    [Regression from 2.21.11, initial connection probing]
    742  1.1  mrg 
    743  1.1  mrg  * Always initialise the gamma ramp, even on unconnected CRTCs.
    744  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=66563
    745  1.1  mrg    [Regression from 2.21.11, initial connection probing]
    746  1.1  mrg 
    747  1.1  mrg  * Some more tuning of the gen4 vertex corruption workaround. The root
    748  1.1  mrg    cause behind the GPU using incorrect texture coordinates is still
    749  1.1  mrg    not solved, but by reducing the maximum number or rectangles in
    750  1.1  mrg    flight through the GPU we reduce the likelihood of corruption.
    751  1.1  mrg 
    752  1.1  mrg  * Fix compilation with gcc-4.5
    753  1.1  mrg    [Regression from 2.21.11]
    754  1.1  mrg 
    755  1.1  mrg  * Avoid integer overflow when performing tiled uploads and operations
    756  1.1  mrg    on very large (>28k pixels wide or tall pixmaps)
    757  1.1  mrg    https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1200766

    759  1.1  mrg 
    760  1.1  mrg Release 2.21.11 (2013-06-30)
    761  1.1  mrg ============================
    762  1.1  mrg An eventful week. What started with a regression with some builds of
    763  1.1  mrg firefox on some machines lead ultimately to the discovery of an older
    764  1.1  mrg kernel bug. Aside from the work to fix the image bug and a few other
    765  1.1  mrg older bugs that were reported and resolved this week, there is also a
    766  1.1  mrg (hopefully) subtle change to the initial configuration of displays. In
    767  1.1  mrg the absence of user overrides in xorg.conf, the DDX will try to preserve
    768  1.1  mrg the same display configuration as used by the kernel, which hopefully
    769  1.1  mrg will be the same configuration as setup by the BIOS. The result should
    770  1.1  mrg be a boot sequence that does not resize at all (aka fastboot) - until
    771  1.1  mrg the display manager takes over and loads a completely different
    772  1.1  mrg configuration!
    773  1.1  mrg 
    774  1.1  mrg  * Add reference counting of drmMaster for ZaphodHeads
    775  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=66041
    776  1.1  mrg

    778  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=51422
    779  1.1  mrg 
    780  1.1  mrg  * Fix occasional missing images for inplace uploads
    781  1.1  mrg    [regression from 2.21.10]
    782  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=66059
    783  1.1  mrg 
    784  1.1  mrg  * Add missing utility files to the tarball and remove a few unused ones
    785  1.1  mrg 
    786  1.1  mrg  * Initialise PolyPoint operand state before calling miWideDash
    787  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=66104
    788  1.1  mrg 
    789  1.1  mrg  * Fix redirection handling for rendering into large surfaces

    791  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=66249
    792  1.1  mrg 
    793  1.1  mrg  * Fix compilation of UXA with xorg-xserver < 1.10
    794  1.1  mrg    [regression from 2.20.0]
    795  1.1  mrg 
    796  1.1  mrg  * Fix consideration of gradients for deciding when to migrate render
    797  1.1  mrg    operations
    798  1.1  mrg    [performance regression from 2.21.10, the bug itself is older]

    863  1.1  mrg ===========================
    864  1.1  mrg A quick release to cleanup a few regressions from the introduction of

    882  1.1  mrg ===========================
    883  1.1  mrg A couple of weeks turned into a month and a couple of weeks... Amidst
    884  1.1  mrg the usual bug fixes, we have added the complete set of Haswell PCI IDs -
    885  1.1  mrg hopefully future proofing ourselves against being surprised by new
    886  1.1  mrg products. We can also now use the correct term for the top of the range
    887  1.1  mrg Haswell variants, GT3.
    888  1.1  mrg 
    889  1.1  mrg  * Fix several assertion failures hit by Jiri Slaby.

    898  1.1  mrg    https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1157678
    899  1.1  mrg

    901  1.1  mrg 
    902  1.1  mrg  * Improve partial migration of render sources.
    903  1.1  mrg 
    904  1.1  mrg  * Fix origin of trapezoids.

    906  1.1  mrg 
    907  1.1  mrg  * Introduce copy-on-write support for cloning pixmaps. The ultimate
    908  1.1  mrg    goal here is to efficiently support the TearFree mode of operation,
    909  1.1  mrg    but this provides immediate benefits with firefox - most importantly
    910  1.1  mrg    because of the inefficient way it now implements scrolling.
    911  1.1  mrg 
    912  1.1  mrg 
    913  1.1  mrg Release 2.21.6 (2013-04-06)
    914  1.1  mrg ===========================
    915  1.1  mrg A surprising highlight of this release is a little refresh to the KMS
    916  1.1  mrg support for OpenBSD. OpenBSD now has its own KMS implementation which is
    917  1.1  mrg mostly compatible with the interface in Linux, with one or two tweaks
    918  1.1  mrg supplied by Mark Kettenis. This release continues to cleanup behaviour
    919  1.1  mrg for Haswell.
    920  1.1  mrg 
    921  1.1  mrg  * Workaround a failure by the xserver to invalidate DRI buffers
    922  1.1  mrg    following a pixmap change for XComposite redirection.
    923  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=62614
    924  1.1  mrg 
    925  1.1  mrg  * Fix computation of clip extents for stippling
    926  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=62618
    927  1.1  mrg 
    928  1.1  mrg  * Support KMS on OpenBSD, by Mark Kettenis
    929  1.1  mrg 
    930  1.1  mrg  * Clean up sockets upon CloseScreen (making ourselves better behaved
    931  1.1  mrg    for muxed setups).
    932  1.1  mrg 
    933  1.1  mrg  * Fix the tests for AVX/AVX2 support in CPUID and remember to check for
    934  1.1  mrg    OS support as well.
    935  1.1  mrg 
    936  1.1  mrg  * Report a monotonic UST value for undisplayed drawables rather than 0
    937  1.1  mrg    by Daniel Kurtz
    938  1.1  mrg 
    939  1.1  mrg  * Fix video playback on gen4 through a complex clip (more gen4 GPU woes)
    940  1.1  mrg    https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1162046
    941  1.1  mrg 
    942  1.1  mrg 
    943  1.1  mrg Release 2.21.5 (2013-03-21)
    944  1.1  mrg ===========================
    945  1.1  mrg Haswell reintroduces a command to load the scanline window from the
    946  1.1  mrg command stream and so requires its own specialised wait-for-vsync routine
    947  1.1  mrg - failure to do so was then causing hangs when trying to do tearfree video
    948  1.1  mrg or use a compositor.
    949  1.1  mrg 
    950  1.1  mrg  * Prevent buffer leak if a non-fullscreen Window is closed with multiple
    951  1.1  mrg    pending swap events.
    952  1.1  mrg 
    953  1.1  mrg  * Fix offset transformation for fallback gradient paths.
    954  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=62198
    955  1.1  mrg 
    956  1.1  mrg  * Prevent Glamor from crashing if misconfigured.
    957  1.1  mrg    Thanks to Michel Dnzer.
    958  1.1  mrg 
    959  1.1  mrg  * Prevent UXA from crashing if torn down during PreInit.
    960  1.1  mrg    Thanks to Aaron Plattner.
    961  1.1  mrg 
    962  1.1  mrg  * Prevent miscompilation with different functional units having different
    963  1.1  mrg    compiler flags. Some functions were expected to be inlined and so
    964  1.1  mrg    recompiled with the current target. However, some compilers were
    965  1.1  mrg    choosing to emit subroutine calls instead without noticing that the
    966  1.1  mrg    ABI was different between the caller and callee - causing corruption.
    967  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=62198
    968  1.1  mrg 
    969  1.1  mrg  * Fix rendering of CompositeTriFan with recent Xorg.
    970  1.1  mrg 
    971  1.1  mrg  * Apply the video src-offset fix highlighted in the last release!
    972  1.1  mrg    A typo prevented the fix from working for gen4+.
    973  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=62343
    974  1.1  mrg 
    975  1.1  mrg  * Fix rendering of multiple glyphs to very large destination surfaces
    976  1.1  mrg    https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1156387
    977  1.1  mrg 
    978  1.1  mrg  * Fix scanline waits for Haswell
    979  1.1  mrg    https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1156679
    980  1.1  mrg 
    981  1.1  mrg 
    982  1.1  mrg Release 2.21.4 (2013-03-11)
    983  1.1  mrg ===========================
    984  1.1  mrg More bugs, more fixes, more releases. A minor new feature being introduced
    985  1.1  mrg is the runtime detection of CPU instructions sets along with specialised
    986  1.1  mrg paths to take advantage of the available CPU.
    987  1.1  mrg 
    988  1.1  mrg  * Honour LinearFramebuffer for clumsy PowerXpress integration
    989  1.1  mrg 
    990  1.1  mrg  * Disable read-read optimisations of mappings whilst the root
    991  1.1  mrg    cause of a corruption issue remains elusive.
    992  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=61628
    993  1.1  mrg 
    994  1.1  mrg  * Disable 8-bpp framebuffers in UXA as the regressions therein
    995  1.1  mrg    remain unfixed.
    996  1.1  mrg 
    997  1.1  mrg  * Restart vertex checks after lock contention
    998  1.1  mrg    https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1124576
    999  1.1  mrg 
   1000  1.1  mrg  * Handle Screen Pixmap recreation whilst exported via PRIME.
   1001  1.1  mrg 
   1002  1.1  mrg  * Correct application of scale factors to video source offsets.
   1003  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=61610
   1004  1.1  mrg 
   1005  1.1  mrg  * Chain up CloseScreen so that resources are actually freed across regen
   1006  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=56608
   1007  1.1  mrg 
   1008  1.1  mrg  * Fix Haswell CRW PCI-IDs
   1009  1.1  mrg 
   1010  1.1  mrg  * Handle batch submission failure during DRI copies
   1011  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=61708
   1012  1.1  mrg 
   1013  1.1  mrg  * Probe for kernel support of requested Screen depth
   1014  1.1  mrg    https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1135403
   1015  1.1  mrg 
   1016  1.1  mrg  * Correct GPU limits for early gen2 and gen3 architectures and prevent
   1017  1.1  mrg    an infinite recursion for particular image sizes.
   1018  1.1  mrg 
   1019  1.1  mrg 
   1020  1.1  mrg Release 2.21.3 (2013-02-20)
   1021  1.1  mrg ===========================
   1022  1.1  mrg A few minor bugfixes, another point release.
   1023  1.1  mrg 
   1024  1.1  mrg  * Fix tracking of DRI pixmaps and their backing bo across reparenting. If
   1025  1.1  mrg    we tried to execute a SwapBuffers after a Window was reparented, but
   1026  1.1  mrg    before the DRI client has updated its references, then we would end up
   1027  1.1  mrg    manipulating an exported pixmap without a flush flag set. In the worst
   1028  1.1  mrg    case, this would culminate in a segfault in the driver.
   1029  1.1  mrg    https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1127497
   1030  1.1  mrg 
   1031  1.1  mrg  * Restore the gen4 workarounds for flickering rendering - a few cases still
   1032  1.1  mrg    remain, as the root cause persists.
   1033  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=60402
   1034  1.1  mrg 
   1035  1.1  mrg  * Double check that the device has KMS enabled before claiming. This allows
   1036  1.1  mrg    X to gracefully fallback to VESA/fbdev rather than bailing out.
   1037  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=60987
   1038  1.1  mrg 
   1039  1.1  mrg  * Fix the UXA render programs for projective transforms on Ivybridge.
   1040  1.1  mrg 
   1041  1.1  mrg 
   1042  1.1  mrg Release 2.21.2 (2013-02-10)
   1043  1.1  mrg ===========================
   1044  1.1  mrg Pass the brown paper bags, I need half a dozen or so. That seemingly
   1045  1.1  mrg innocuous build fix with xorg-1.13 happened to have the little side-effect
   1046  1.1  mrg of breaking glyph rendering with xorg-1.12 and older on 64-bit machines.
   1047  1.1  mrg 
   1048  1.1  mrg 
   1049  1.1  mrg Release 2.21.1 (2013-02-10)
   1050  1.1  mrg ===========================
   1051  1.1  mrg A fix for a potential GPU hang on 945gm (GMA950) and earlier chipsets,
   1052  1.1  mrg along with backporting SNA to the packages found in stable distributions
   1053  1.1  mrg like Debian 6.0 (Squeeze).
   1054  1.1  mrg 
   1055  1.1  mrg  * Cleanup compilation warnings from deblint, thanks to Paul Menzel
   1056  1.1  mrg 
   1057  1.1  mrg  * Minor build improvements by Damien Lespiau.
   1058  1.1  mrg 
   1059  1.1  mrg  * Disable generating span geometry for non-rectilinear spans on gen4
   1060  1.1  mrg    in order to work around and prevent one class of render corruption.
   1061  1.1  mrg 
   1062  1.1  mrg  * Prevent cache thrashing and severe performance degradation on LLC
   1063  1.1  mrg    machines for streaming texture updates. However, note the effect was
   1064  1.1  mrg    only observed on just one particular laptop.
   1065  1.1  mrg 
   1066  1.1  mrg  * Fix alignment of subsurface proxies for old chipsets.
   1067  1.1  mrg    https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1120108
   1068  1.1  mrg 
   1069  1.1  mrg  * Repair build against Xserver-1.6 and contemporary packages.
   1070  1.1  mrg 
   1071  1.1  mrg 
   1072  1.1  mrg Release 2.21.0 (2013-02-01)
   1073  1.1  mrg ===========================
   1074  1.1  mrg A few new features:
   1075  1.1  mrg 
   1076  1.1  mrg  * Enable render acceleration for Haswell GT1/GT2.
   1077  1.1  mrg 
   1078  1.1  mrg  * Enable multi-threaded rasterisation of trapezoids and fallback composition
   1079  1.1  mrg 
   1080  1.1  mrg  * Utilise a new kernel interface (v3.9) for processing relocations
   1081  1.1  mrg 
   1082  1.1  mrg along with a few older features from the 2.20.x series:
   1083  1.1  mrg 
   1084  1.1  mrg  * PRIME support for hotplug GPUs and hybrid systems
   1085  1.1  mrg 
   1086  1.1  mrg  * Support for IvyBridge GT1 machines, aka HD2500 graphics.
   1087  1.1  mrg 
   1088  1.1  mrg  * Stable 830gm/845g support, at last!
   1089  1.1  mrg 
   1090  1.1  mrg As usual we have a large number of bug fixes since the last release:
   1091  1.1  mrg 
   1092  1.1  mrg  * Prevent a stray relocation being left after a buffer is removed from
   1093  1.1  mrg    a batch, leading to GPU hangs.
   1094  1.1  mrg 
   1095  1.1  mrg  * Make the driver more robust against its own failures to submit batches
   1096  1.1  mrg    by falling back to software rendering.
   1097  1.1  mrg 
   1098  1.1  mrg  * Fix emission of scanline waits for secondary pipes on gen6/7. Otherwise
   1099  1.1  mrg    you may encounter GPU hangs in MI_WAIT_FOR_EVENT.
   1100  1.1  mrg 
   1101  1.1  mrg  * Fix a missing corner pixel when drawing rectangles with PolyLines
   1102  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=55484
   1103  1.1  mrg 
   1104  1.1  mrg  * Don't try to use Y-tiling colour buffers with mesa/i915c as mesa
   1105  1.1  mrg    doesn't support them and wil fallback to software rendering
   1106  1.1  mrg 
   1107  1.1  mrg  * Ensure that any cached mmaps are invalidated for a SwapBuffers
   1108  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=60042
   1109  1.1  mrg 
   1110  1.1  mrg  * Correctly handle the composition of rotated displays too large for the
   1111  1.1  mrg    3D pipeline
   1112  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=60124
   1113  1.1  mrg 
   1114  1.1  mrg  * Fix the computation of the planar video frame size
   1115  1.1  mrg    https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1104180
   1116  1.1  mrg 
   1117  1.1  mrg 
   1118  1.1  mrg Release 2.20.19 (2013-01-20)
   1119  1.1  mrg ============================
   1120  1.1  mrg A quick release as the last broke USB DisplayLink slave outputs badly. The
   1121  1.1  mrg performance of those displays was unusable due to an inadvertent change that
   1122  1.1  mrg caused us to flush the entire scanout over the USB for every drawing
   1123  1.1  mrg operation.
   1124  1.1  mrg 
   1125  1.1  mrg  * Implement the GNOME Build API. A couple of minor changes to make
   1126  1.1  mrg    integrators and distributors lives a little easier, or at least more
   1127  1.1  mrg    consistent.
   1128  1.1  mrg 
   1129  1.1  mrg  * Correctly offset inplace trapezoids for subwindows, such as the GTK+
   1130  1.1  mrg    close button after it has a background image uploaded.
   1131  1.1  mrg 
   1132  1.1  mrg  * Explicitly prevent ring-switching for synchronized rendering to
   1133  1.1  mrg    scanouts (for vsync).
   1134  1.1  mrg 
   1135  1.1  mrg  * Clip dirty region to slave pixmaps (otherwise UDL is nigh unusuable)
   1136  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=59539
   1137  1.1  mrg 
   1138  1.1  mrg 
   1139  1.1  mrg Release 2.20.18 (2013-01-16)
   1140  1.1  mrg ============================
   1141  1.1  mrg A bunch of miscellaneous fixes for assertion failures and various
   1142  1.1  mrg performance regressions when mixing new methods for offloads, along with
   1143  1.1  mrg a couple of improvements for rendering with gen4.
   1144  1.1  mrg 
   1145  1.1  mrg  * Remove use of packed unnormalized texture coordinates on gen4/5 as
   1146  1.1  mrg    these GPUs do not support unnormalized coordinates in the sampler.
   1147  1.1  mrg 
   1148  1.1  mrg  * Remove dependency upon x86 asm for cross-building to unsupported
   1149  1.1  mrg    architectures.
   1150  1.1  mrg    https://bugs.gentoo.org/show_bug.cgi?id=448570
   1151  1.1  mrg 
   1152  1.1  mrg  * Apply damage around PRIME updates in the correct order.
   1153  1.1  mrg 
   1154  1.1  mrg  * Correctly read the initial backlight level for when the user
   1155  1.1  mrg    overrides UXA's choice of backlight controller.
   1156  1.1  mrg 
   1157  1.1  mrg  * Throttle UXA and prevent it queuing work much faster than the GPU can
   1158  1.1  mrg    complete it. This realised itself in impossible performance figures and
   1159  1.1  mrg    the entire display freezing for several seconds whlist the GPU caught
   1160  1.1  mrg    up. One side effect is that it also caused the DDX to consume more
   1161  1.1  mrg    memory than was required as it could not recycle buffers quick
   1162  1.1  mrg    enough, and in some cases this produces a marked improvement in
   1163  1.1  mrg    performance. Also note on gen2/3 this requires a new libdrm [2.4.41]
   1164  1.1  mrg    in order to prevent a bug causing the DDX to fallback to swrast.
   1165  1.1  mrg 
   1166  1.1  mrg Release 2.20.17 (2012-12-26)
   1167  1.1  mrg ============================
   1168  1.1  mrg A minor update to prepare for co-operating with the kernel over managing
   1169  1.1  mrg stability on 830gm/845g. On this pair of chipsets, the kernel will perform
   1170  1.1  mrg an extra copy of the batchbuffer into reserved memory, which prevents them
   1171  1.1  mrg from randomly dying. However, that extra copy does have a noticeable
   1172  1.1  mrg impact upon throughput, so we also have a mechanism for userspace to
   1173  1.1  mrg opt-out of the kernel workaround and take responsibility for ensuring its
   1174  1.1  mrg batches are coherent.
   1175  1.1  mrg 
   1176  1.1  mrg  * Build fixes against xorg-1.14
   1177  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=58552
   1178  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=58406
   1179  1.1  mrg 
   1180  1.1  mrg  * Fixed the origin of cropped (textured) video windows (Xv and XvMC)
   1181  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=23033
   1182  1.1  mrg 
   1183  1.1  mrg  * Fix potential corruption when using images larger than ~1GiB
   1184  1.1  mrg 
   1185  1.1  mrg 
   1186  1.1  mrg Release 2.20.16 (2012-12-15)
   1187  1.1  mrg ============================
   1188  1.1  mrg Rejoice! We have found a trick to make 830gm/845g stable at long last.
   1189  1.1  mrg Ever since the switch to GEM and dynamic video memory, those early
   1190  1.1  mrg second generation chipsets have been plagued by instability. The lack of
   1191  1.1  mrg flushing cachelines from the CPU to GMCH was eventually solved by using
   1192  1.1  mrg an undocmented bit, but 830/845 were still hanging under memory pressure.
   1193  1.1  mrg These deaths were all due to garbage finding its way into the command
   1194  1.1  mrg streamer, and they go away if we take a leaf out of the original driver
   1195  1.1  mrg and never reuse those pages for anything else. So for the first time
   1196  1.1  mrg ever, I have been able to complete running the test suite on an 845g,
   1197  1.1  mrg even whilst thrashing the page and buffer caches!
   1198  1.1  mrg 
   1199  1.1  mrg  * Run the SF stage as single-threaded on gen4 to workaround a few issues
   1200  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=57410
   1201  1.1  mrg 
   1202  1.1  mrg  * Keep the scanout SURFACE_STATE separate to avoid overriding its
   1203  1.1  mrg    memory access control on gen6/7 (i.e. writes to the scanout need to
   1204  1.1  mrg    be kept out of the render cache)
   1205  1.1  mrg 
   1206  1.1  mrg  * Tune batch flushing after an operation to an exported surface under a
   1207  1.1  mrg    compositor.
   1208  1.1  mrg 
   1209  1.1  mrg  * Make sure the source is on the CPU for inplace composition of trapezoids
   1210  1.1  mrg    using the CPU
   1211  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=56825
   1212  1.1  mrg 
   1213  1.1  mrg  * Immediately flush in the block hander after a split batch to reduce
   1214  1.1  mrg    latency between the two halves of an operation.
   1215  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=51718
   1216  1.1  mrg 
   1217  1.1  mrg  * Install a fallback config if we fail to install the desired config
   1218  1.1  mrg    at VT switch (i.e. booting, after resume with 3 incompatible pipes on
   1219  1.1  mrg    Ivybridge)
   1220  1.1  mrg 
   1221  1.1  mrg  * Pin batches to avoid CS incoherence on 830/845

   1225  1.1  mrg Release 2.20.15 (2012-12-03)
   1226  1.1  mrg ============================
   1227  1.1  mrg And lo, enabling more of the common acceleration paths for gen4 revealed
   1228  1.1  mrg another lurking bug - something is wrong with how we prepare Y-tiling
   1229  1.1  mrg surfaces for rendering. For the time being, we can surreptiously disable
   1230  1.1  mrg them for gen4 and avoid hitting GPU hangs.
   1231  1.1  mrg 
   1232  1.1  mrg  * Avoid clobbering the render state after failing to convert the
   1233  1.1  mrg    operation to use the blitter.
   1234  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=57601
   1235  1.1  mrg 
   1236  1.1  mrg  * Disable shadow tracking upon server regeneration, and so fix a crash
   1237  1.1  mrg    if you restart the server whilst a RandR transform (e.g. rotation) is
   1238  1.1  mrg    in effect.

   1243  1.1  mrg Release 2.20.14 (2012-11-26)
   1244  1.1  mrg ============================
   1245  1.1  mrg The highlight of this release is gen4, from 965g to gm45. Quite an old
   1246  1.1  mrg bug surfaced in the shader assembly, sparking a chance to review a few
   1247  1.1  mrg design choices within that backend and experiment on fresh ways to
   1248  1.1  mrg workaround the remaining issues.
   1249  1.1  mrg 
   1250  1.1  mrg  * Avoid using inplace XOR'ed uploads for very large buffers
   1251  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=57031
   1252  1.1  mrg 
   1253  1.1  mrg  * Fix the gen4/5 opacity shader

   1255  1.1  mrg 
   1256  1.1  mrg  * Queue a pending vblank request after flip completion

   1258  1.1  mrg 
   1259  1.1  mrg  * Avoid migrating an uninitialised pixmap for use as a render source
   1260  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=47597
   1261  1.1  mrg 
   1262  1.1  mrg  * Improve handing of texture fallbacks for 830/845.

   1264  1.1  mrg 
   1265  1.1  mrg 
   1266  1.1  mrg Release 2.20.13 (2012-11-11)
   1267  1.1  mrg ============================
   1268  1.1  mrg Nothing but bug fixes. Many thanks to everyone who took the time to
   1269  1.1  mrg report their issues, and for their help in improving the driver.
   1270  1.1  mrg 
   1271  1.1  mrg  * Sanity check the platform probe points to our expected i915 device
   1272  1.1  mrg    https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1069031
   1273  1.1  mrg 
   1274  1.1  mrg  * Prevent 16-bit overflow for computing the sample area to upload of
   1275  1.1  mrg    sources for render operations
   1276  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=56324
   1277  1.1  mrg 
   1278  1.1  mrg  * Clamp the drawable box for migration to prevent 16-bit overflow
   1279  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=56591
   1280  1.1  mrg 
   1281  1.1  mrg  * Disable RandR hotplug events if Xinerama is enabled and thereby prevent
   1282  1.1  mrg    a crash upon hotplug
   1283  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=55260
   1284  1.1  mrg 
   1285  1.1  mrg  * Call ValidatePicture before attempting to flatten the alphamaps
   1286  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=56367
   1287  1.1  mrg 
   1288  1.1  mrg  * Clip the trapezoid correctly if it ends on the boundary pixel
   1289  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=56395
   1290  1.1  mrg 
   1291  1.1  mrg  * Make sure the pipeline choice is propagated to the scanline wait
   1292  1.1  mrg    across a batch flush
   1293  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=47597
   1294  1.1  mrg 
   1295  1.1  mrg  * Set the valid drawable box when choosing placement of BLT composite ops
   1296  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=47597
   1297  1.1  mrg 
   1298  1.1  mrg  * Prevent use-after-free when promoting a partial-GPU bo to a full-GPU bo
   1299  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=56591
   1300  1.1  mrg 
   1301  1.1  mrg  * gen4 opacity spans require the per-rectangle workaround
   1302  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=55500
   1303  1.1  mrg 
   1304  1.1  mrg  * Prevent use of invalid damage pointers when redirecting rendering

   1306  1.1  mrg 
   1307  1.1  mrg 
   1308  1.1  mrg Release 2.20.12 (2012-10-20)
   1309  1.1  mrg ============================
   1310  1.1  mrg More bug reports, more bug fixes! Perhaps the headline feature is
   1311  1.1  mrg that with a secure batches, coming to a 3.8 kernel near you, we may
   1312  1.1  mrg finally have the ability to perform updates to the scanout synchronized
   1313  1.1  mrg to the refresh rate on later SandyBridge and IvyBridge chipsets. It comes
   1314  1.1  mrg at quite a power cost as we need to keep the GPU out of its power saving
   1315  1.1  mrg modes, but it should allow legacy vsync to function at last. But this
   1316  1.1  mrg should allow us to address a longstanding issue with tearing on
   1317  1.1  mrg SandyBridge+.
   1318  1.1  mrg 
   1319  1.1  mrg  * Fix component-alpha rendering on IvyBridge, for example subpixel
   1320  1.1  mrg    antialiased glyphs.
   1321  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=56037
   1322  1.1  mrg 
   1323  1.1  mrg  * Flush before some "pipelined" state changes on gen4. The evidence is
   1324  1.1  mrg    that the same flushes as required on gen5+ are also required for gen4.
   1325  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=55627
   1326  1.1  mrg 
   1327  1.1  mrg  * Prevent a potential crash when forcing a stall on a busy CPU bo
   1328  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=56180
   1329  1.1  mrg 
   1330  1.1  mrg [Release 2.20.11 contained a typo causing UXA to fail immediately.]
   1331  1.1  mrg 
   1332  1.1  mrg Release 2.20.10 (2012-10-14)
   1333  1.1  mrg ============================
   1334  1.1  mrg The last couple of weeks have been fairly retrospective, a dive into
   1335  1.1  mrg prehistory tidying up the earlier generations which lay languishing as
   1336  1.1  mrg the core progressed and lead to a number of annoying core bugs being
   1337  1.1  mrg fixed.
   1338  1.1  mrg 
   1339  1.1  mrg  * Release DRM master earlier during shutdown so switching between
   1340  1.1  mrg    multiple X servers works automatically.
   1341  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=55446
   1342  1.1  mrg 
   1343  1.1  mrg  * Suppress error propagation from DRI2GetMSC and behave as if the pipe
   1344  1.1  mrg    was simply off to avoid unexpected errors in the clients
   1345  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=55395
   1346  1.1  mrg 
   1347  1.1  mrg  * A few fixes to i8xx batch emission, ensuring that the GPU is always
   1348  1.1  mrg    in a valid state.
   1349  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=55455
   1350  1.1  mrg 
   1351  1.1  mrg  * Prevent a use-after-free during UXA shutdown due to inspecting
   1352  1.1  mrg    the glamor flags after the glamor interface had been freed.
   1353  1.1  mrg 
   1354  1.1  mrg  * Prevent a crash combining TearFree and rotations.
   1355  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=55527
   1356  1.1  mrg 
   1357  1.1  mrg  * Correct a missing damage upload along PutImage after using the CPU bo
   1358  1.1  mrg    as a source for the GPU.
   1359  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=55508
   1360  1.1  mrg 
   1361  1.1  mrg  * Fix compilation for older glibc without O_CLOEXEC
   1362  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=55577
   1363  1.1  mrg 
   1364  1.1  mrg  * Fix out-of-tree builds failing to recompile the gen4 assemblies
   1365  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=55645
   1366  1.1  mrg 
   1367  1.1  mrg  * Fix non-standard build host configuration handling for intel-gen4asm
   1368  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=55646
   1369  1.1  mrg 
   1370  1.1  mrg  * Fix a potential batch buffer overflow when replacing the last BLT fill
   1371  1.1  mrg    operation with a copy
   1372  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=55700
   1373  1.1  mrg 
   1374  1.1  mrg  * Flush the render pipeline more frequently on Ironlake as not all
   1375  1.1  mrg    pipelined state changes are.
   1376  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=51422
   1377  1.1  mrg 
   1378  1.1  mrg  * Detect when we need to read the destination for the background raster
   1379  1.1  mrg    op during fallbacks.
   1380  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=55810
   1381  1.1  mrg 
   1382  1.1  mrg  * Avoid a potential deference of an invalid CPU mmap after doing an
   1383  1.1  mrg    inplace tiled upload.
   1384  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=55812
   1385  1.1  mrg 
   1386  1.1  mrg  * Prevent sign extension when packing the upload data for CopyPlane
   1387  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=55823
   1388  1.1  mrg 
   1389  1.1  mrg  * Fix some render corruption with a UDL slave output and pageflipping
   1390  1.1  mrg 
   1391  1.1  mrg 
   1392  1.1  mrg Release 2.20.9 (2012-09-29)
   1393  1.1  mrg ===========================
   1394  1.1  mrg And so it came to pass that a critical bug was uncovered in UXA. The
   1395  1.1  mrg kernel does not like to pageflip when the pipe is off, yet due to the
   1396  1.1  mrg delayed nature of a pageflip and the relaxed checking performed by UXA,
   1397  1.1  mrg we could request a pageflip after turning off the display (DPMS). The
   1398  1.1  mrg kernel rejected that pageflip and the error handling path failed to
   1399  1.1  mrg restore sanity, and when the screen came back it was stuck on the image
   1400  1.1  mrg seen before it went to sleep. (Note that there are also some related
   1401  1.1  mrg kernel bugs, but this update should prevent the most conspicious of the
   1402  1.1  mrg freezes.) Many thanks to Timo Aaltonen for his efforts in tracking down
   1403  1.1  mrg the issue.
   1404  1.1  mrg 
   1405  1.1  mrg In other news:
   1406  1.1  mrg 
   1407  1.1  mrg   * Prepare for xorg-1.14, the api is being tweaked again.
   1408  1.1  mrg 
   1409  1.1  mrg   * Handle early FreeScreen in UXA.

   1419  1.1  mrg 
   1420  1.1  mrg Release 2.20.8 (2012-09-16)
   1421  1.1  mrg ===========================
   1422  1.1  mrg Another new small feature, another new release. And a few more bugs
   1423  1.1  mrg fixed as well! But what is this new feature, do I hear you ask? Why, it
   1424  1.1  mrg is nothing less than enabling the ValleyView SDV! The lucky person to
   1425  1.1  mrg have their hands on one will now be able to enjoy X in full TechniColor.
   1426  1.1  mrg 
   1427  1.1  mrg For the rest of us, a few more bugs were fixed with interesting
   1428  1.1  mrg combinations of software and rendering patterns.
   1429  1.1  mrg 
   1430  1.1  mrg  * Add an extra layer of defence against trying to use a non-GEM device
   1431  1.1  mrg    with UXA. This should already be taken care of with the new probe,
   1432  1.1  mrg    but the extra sanity check already existed in the code but was doing
   1433  1.1  mrg    nothing.

   1435  1.1  mrg 
   1436  1.1  mrg  * Fix computation of valid CRTCs bitmask for ZaphodHead
   1437  1.1  mrg    Some systems can only handle certain outputs on certain pipes
   1438  1.1  mrg    (Screens), and this information was not being propagated through to X
   1439  1.1  mrg    and randr correctly, breaking valid configurations and not detecting
   1440  1.1  mrg    invalid configurations correctly.
   1441  1.1  mrg 
   1442  1.1  mrg  * Disable global glyph caching with ZaphodHeads.
   1443  1.1  mrg    The glyph privates need to be Screen private, but at the moment are
   1444  1.1  mrg    global leading to conflicts and invalid rendering with multiple heads.

   1452  1.1  mrg

   1456  1.1  mrg 
   1457  1.1  mrg  * Correct a minor typo in flattening alphamaps which caused the
   1458  1.1  mrg    replacement pixmap to often end up with a height of zero.
   1459  1.1  mrg    https://bugs.gentoo.org/show_bug.cgi?id=434860
   1460  1.1  mrg 
   1461  1.1  mrg  * Don't discard the CPU damage if only part of is being replaced.
   1462  1.1  mrg    This is most evident when combining software renders like Opera with
   1463  1.1  mrg    accelerated rendering.

   1470  1.1  mrg support and the ability to offload DRI rendering onto other GPUs. In
   1471  1.1  mrg light of that advance, this release includes the support code by Dave
   1472  1.1  mrg Airlie to integrate PRIME into xf86-video-intel and make those new
   1473  1.1  mrg features available.
   1474  1.1  mrg 
   1475  1.1  mrg Aside from landing PRIME, a few other bugs were fixed since 2.20.6:
   1476  1.1  mrg 
   1477  1.1  mrg  * Fix framebuffer leak on server regeneration
   1478  1.1  mrg 
   1479  1.1  mrg  * Fix texture cache flushing on IvyBridge and Kwin with plastique
   1480  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=54488
   1481  1.1  mrg 
   1482  1.1  mrg  * Redirect large solid fills on SandyBridge+. By large I mean greater
   1483  1.1  mrg    than 8192 or 16384 pixels on SandyBridge and IvyBridge respectively.
   1484  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=54134
   1485  1.1  mrg 
   1486  1.1  mrg  * Fix up backlight option handling in the manpage and uxa.
   1487  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=54397
   1488  1.1  mrg 
   1489  1.1  mrg  * Unbreak ZaphodHeads.
   1490  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=52438
   1491  1.1  mrg 
   1492  1.1  mrg Release 2.20.6 (2012-09-02)
   1493  1.1  mrg ===========================
   1494  1.1  mrg A serious bug that caused a crash on SandyBridge and IvyBridge when
   1495  1.1  mrg mixing CPU and GPU operations on the same buffer, and an annoyance from
   1496  1.1  mrg bad scheduling of windowed swapbuffer updates causing low framerates and
   1497  1.1  mrg jitter. Plus the usual smattering of assertion fixes and a long standing
   1498  1.1  mrg issue with incoherent page access to a streaming buffer.
   1499  1.1  mrg 
   1500  1.1  mrg  * Low frame rates in Blobby Valley when "fullscreen"
   1501  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=54274
   1502  1.1  mrg 
   1503  1.1  mrg  * Incoherent concurrent access with the CPU and GPU
   1504  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=51422
   1505  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=52299
   1506  1.1  mrg 
   1507  1.1  mrg  * Add Option "Backlight" to override automatic selection of the
   1508  1.1  mrg    backlight interface.
   1509  1.1  mrg 
   1510  1.1  mrg  * Avoid overwriting the composite operation info when testing if we
   1511  1.1  mrg    can transfer the operation to the BLT.
   1512  1.1  mrg 
   1513  1.1  mrg Release 2.20.5 (2012-08-26)
   1514  1.1  mrg ===========================
   1515  1.1  mrg Another silly bug found, another small bugfix release. The goal was for
   1516  1.1  mrg the driver to bind to all Intel devices supported by the kernel.
   1517  1.1  mrg Unfortunately we were too successful and started claiming Pouslbo,
   1518  1.1  mrg Medfield and Cedarview devices which are still encumbered by propietary
   1519  1.1  mrg IP and not supported by this driver.
   1520  1.1  mrg 
   1521  1.1  mrg Bugs fixed since 2.20.4:
   1522  1.1  mrg 
   1523  1.1  mrg  * Only bind to Intel devices using the i915 kernel module
   1524  1.1  mrg 
   1525  1.1  mrg  * Regression in the bitmap-to-region code, e.g. icewm window buttons
   1526  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=53699
   1527  1.1  mrg 
   1528  1.1  mrg Release 2.20.4 (2012-08-18)
   1529  1.1  mrg ===========================
   1530  1.1  mrg Continuing the small bugfix releases, the only real feature is initial
   1531  1.1  mrg enabling for Haswell for the purpose of rendering verification and
   1532  1.1  mrg validation - by no means is it complete!
   1533  1.1  mrg 
   1534  1.1  mrg Bugs fixed since 2.20.3:
   1535  1.1  mrg 
   1536  1.1  mrg   * Some potential errors along failure paths found by a static analyser
   1537  1.1  mrg   with the help of Zdenek Kablac.
   1538  1.1  mrg 
   1539  1.1  mrg   * Eliminate zero-sized rectangles from PolyFillRectangles as the code
   1540  1.1  mrg   assumes that they did not exist and so caused corruption.
   1541  1.1  mrg 
   1542  1.1  mrg   * Remove the UXA warning for failing to tile the front buffer if it is
   1543  1.1  mrg   disallowed by hardware, and so expected.
   1544  1.1  mrg 
   1545  1.1  mrg   * Fix the validation of the XV pipe parameter.
   1546  1.1  mrg 
   1547  1.1  mrg   * Fix 8x8 tiled pattern fills
   1548  1.1  mrg   https://bugs.freedesktop.org/show_bug.cgi?id=53353
   1549  1.1  mrg 
   1550  1.1  mrg   * Fix compile failure when using --with-builderstring
   1551  1.1  mrg 
   1552  1.1  mrg   * Restore w/a flush for gen4 fill/copy/video, fortunately rare
   1553  1.1  mrg   operations as at least for fill/copy we prefer to use the BLT.
   1554  1.1  mrg   https://bugs.freedesktop.org/show_bug.cgi?id=53119
   1555  1.1  mrg 
   1556  1.1  mrg   * Restore preferred use of the RENDER ring for SNB+ DRI copies.
   1557  1.1  mrg 
   1558  1.1  mrg Release 2.20.3 (2012-08-04)
   1559  1.1  mrg ===========================
   1560  1.1  mrg Just a minor bugfix for gen4 chipsets (965gm, gm45 and friends) that
   1561  1.1  mrg crept into 2.20.2. As an added bonus, the pessimistic workaround for a
   1562  1.1  mrg GPU hang on gen4 has been relaxed and the shaders have been overhauled
   1563  1.1  mrg which should pave the way to eliminating the last of the uncommon CPU
   1564  1.1  mrg operations, along with immediately realising a small perforamnce
   1565  1.1  mrg improvement.
   1566  1.1  mrg 
   1567  1.1  mrg Bugs fixed since 2.20.2:
   1568  1.1  mrg 
   1569  1.1  mrg  * Update DPMS bookkeeping after modeset
   1570  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=52142
   1571  1.1  mrg 
   1572  1.1  mrg  * Avoid overlapping gpu/cpu damage after ignoring cpu damage in the
   1573  1.1  mrg    consideration of placement for the operation.
   1574  1.1  mrg 
   1575  1.1  mrg  * Enable acceleration by default on 830gm/845g. The GMCH on this pair
   1576  1.1  mrg    of chipsets is notoriously incoherent, so the GPU is almost certainly
   1577  1.1  mrg    going to hang at some point, though unlikely to hang the system and
   1578  1.1  mrg    should automatically disable acceleration (and thence behave
   1579  1.1  mrg    identically as if the acceleration was disabled from the start).
   1580  1.1  mrg    Option "NoAccel" can be used to disable all 2D acceleration and
   1581  1.1  mrg    Option "DRI" can be used to disable all 3D acceleration.
   1582  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=52624
   1583  1.1  mrg 
   1584  1.1  mrg  * Fix vertex bookkeeping for gen4 that was causing corruption in the
   1585  1.1  mrg    command stream.
   1586  1.1  mrg 
   1587  1.1  mrg Release 2.20.2 (2012-07-27)
   1588  1.1  mrg ===========================
   1589  1.1  mrg For the last 9 months, since 2.16.901, we have been shipping a driver that
   1590  1.1  mrg does not work on IvyBridge GT1 systems (HD2500 graphics); we were telling
   1591  1.1  mrg the GPU to use an invalid number of threads for the pixel shader and this
   1592  1.1  mrg in turned caused the GPU to hang.
   1593  1.1  mrg 
   1594  1.1  mrg Also fixed since the last release just a few days ago:
   1595  1.1  mrg 
   1596  1.1  mrg * Support for the gmux backlight controller on Apple laptops
   1597  1.1  mrg   https://bugs.freedesktop.org/show_bug.cgi?id=52423
   1598  1.1  mrg 
   1599  1.1  mrg * Fix X -configure not to list this driver as matching any Intel device,
   1600  1.1  mrg   just the VGA class devices will do!
   1601  1.1  mrg 
   1602  1.1  mrg * A crash in SNA when repeatedly switching xrandr rotations
   1603  1.1  mrg 
   1604  1.1  mrg * Corruption in SNA observed in kwin on IvyBridge
   1605  1.1  mrg   https://bugs.freedesktop.org/show_bug.cgi?id=52473
   1606  1.1  mrg 
   1607  1.1  mrg Release 2.20.1 (2012-07-22)
   1608  1.1  mrg ===========================
   1609  1.1  mrg A week in, grab the brown paper bags, for it is time to reveal a couple
   1610  1.1  mrg of critical bugs that spoilt the 2.20.0 release.
   1611  1.1  mrg 
   1612  1.1  mrg Firstly we have the restoration of DRI for i810. I am sure that the
   1613  1.1  mrg solitary user will be overjoyed in a couple of years when a new xserver
   1614  1.1  mrg is forced upon him. That enjoyment will be short-lived when as no actual
   1615  1.1  mrg acceleration remains, not even shadow, for the chipset.
   1616  1.1  mrg 
   1617  1.1  mrg Perhaps a little more wildly felt, I hope!, will be that the SNA
   1618  1.1  mrg fallbacks were broken on 64-bit machines if they required clipping. One
   1619  1.1  mrg little misplaced cast of a pointer, and the screen is filled with
   1620  1.1  mrg corruption.
   1621  1.1  mrg 
   1622  1.1  mrg Among the other tweaks this week:
   1623  1.1  mrg 
   1624  1.1  mrg * A bug affecting gen4 handling of trapezoids was fixed, and CPU
   1625  1.1  mrg   overhead reduced.
   1626  1.1  mrg   https://bugs.freedesktop.org/show_bug.cgi?id=52158
   1627  1.1  mrg 
   1628  1.1  mrg * A fix for a bug causing corruption of a DRI2 unredirected client
   1629  1.1  mrg   window that was resized whilst under a compositor.
   1630  1.1  mrg 
   1631  1.1  mrg * Support for snoopable buffers on non-LLC architectures, coming to
   1632  1.1  mrg   a future kernel. The aim to accelerate transfers between the CPU
   1633  1.1  mrg   and the GPU, in particular to dramatically improve readback
   1634  1.1  mrg   performance, and to further minimise clflushes.
   1635  1.1  mrg 
   1636  1.1  mrg * Improvement to the composite performance on GT2 SandyBridge and
   1637  1.1  mrg   IvyBridge devices, in particular the render copy is significantly
   1638  1.1  mrg   improved.
   1639  1.1  mrg 
   1640  1.1  mrg * Improved handling for when acceleration is disabled, including
   1641  1.1  mrg   permitting DRI2 to remain supported even if the X server believes
   1642  1.1  mrg   the GPU wedged.
   1643  1.1  mrg 
   1644  1.1  mrg * Shadow support was dropped from UXA as it was neither complete nor
   1645  1.1  mrg   correct, use SNA instead.
   1646  1.1  mrg 
   1647  1.1  mrg Release 2.20.0 (2012-07-15)
   1648  1.1  mrg ===========================
   1649  1.1  mrg First the big news, a new acceleration method that aims to be faster and
   1650  1.1  mrg consume far less CPU than UXA is now available for selection at runtime.
   1651  1.1  mrg This snazzy new architecture can be selected through use of
   1652  1.1  mrg   Option "AccelMethod" "sna"
   1653  1.1  mrg in your xorg.conf. Whilst it has been under development for some time, it
   1654  1.1  mrg has not yet had the same degree of widespread testing of UXA, so tread
   1655  1.1  mrg lightly. Try it and if you spot anything that can be improved, please do
   1656  1.1  mrg report a bug.
   1657  1.1  mrg 
   1658  1.1  mrg Otherwise we have the usual smattering of bug fixes for UXA:
   1659  1.1  mrg 
   1660  1.1  mrg  * Use a white source whilst adding glyphs to the glyph mask
   1661  1.1  mrg    (This fixes blank glyphs if using a font that mixes ARGB and A glyphs.)
   1662  1.1  mrg 
   1663  1.1  mrg  * Avoid fallbacks for glyph-to-dst in e.g. gnome-terminal
   1664  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=50508
   1665  1.1  mrg 
   1666  1.1  mrg  * Force unused outputs off when VT switching
   1667  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=50772
   1668  1.1  mrg 
   1669  1.1  mrg  * Copy the fbcon across to the Screen pixmap at startup.
   1670  1.1  mrg    (This patch has been kicking around in the distributions for years.)
   1671  1.1  mrg 
   1672  1.1  mrg  * Many missed malloc failures checks and forgotten frees found by a static
   1673  1.1  mrg    analyzer. Thanks Zdenek Kabelac!
   1674  1.1  mrg 
   1675  1.1  mrg  * Leak of the back buffer when terminating an application after pageflipping
   1676  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=50670
   1677  1.1  mrg 
   1678  1.1  mrg  * Double check that the pipe is on before emitting a WAIT_ON_EVENT.
   1679  1.1  mrg    In conjunction with an uptodate kernel, this should eliminate any
   1680  1.1  mrg    hangs when changing resolutions or adding/removing displays.
   1681  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=50668
   1682  1.1  mrg 
   1683  1.1  mrg  * Update to new Xorg APIs. Future proofing for the next generation of
   1684  1.1  mrg    hotplug Xorg display servers.
   1685  1.1  mrg 
   1686  1.1  mrg Many thanks to everyone who has reported a bug and otherwise helped to
   1687  1.1  mrg improve the driver.
   1688  1.1  mrg 
   1689  1.1  mrg Release 2.19.0 (2012-04-29)
   1690  1.1  mrg ===========================
   1691  1.1  mrg More stability fixes for UXA and support for another variant of IvyBridge.
   1692  1.1  mrg Given the severity of the stability fixes, I strongly recommend everybody
   1693  1.1  mrg to upgrade to 2.19.0.
   1694  1.1  mrg 
   1695  1.1  mrg * Prevent waiting on scanlines whilst not in control of the VT and therefore
   1696  1.1  mrg   whilst referencing foreign CRTC configurations.
   1697  1.1  mrg 
   1698  1.1  mrg * Pixmap (and bo leak) during fallback glyph composition
   1699  1.1  mrg 
   1700  1.1  mrg * Remove broken acceleration for rendering glyphs directly upon the
   1701  1.1  mrg   destination pixmap, exposed by cairo-1.12.0 (and coincidentally fix
   1702  1.1  mrg   another Pixmap leak upon fallback handling).
   1703  1.1  mrg 
   1704  1.1  mrg * Add support for Ivy Bridge GT2 Server chipset [PCI id 0x016a]
   1705  1.1  mrg 
   1706  1.1  mrg * Remove broken damage flushing with CompositeRectangles
   1707  1.1  mrg   https://bugs.freedesktop.org/show_bug.cgi?id=32547
   1708  1.1  mrg 
   1709  1.1  mrg * Fix crash upon server start with multiple monitors
   1710  1.1  mrg   https://bugs.freedesktop.org/show_bug.cgi?id=47395
   1711  1.1  mrg 
   1712  1.1  mrg * Fix composition issues resulting from overly aggressive Pixmap reuse
   1713  1.1  mrg   https://bugs.freedesktop.org/show_bug.cgi?id=47345
   1714  1.1  mrg 
   1715  1.1  mrg Release 2.18.0 (2012-02-24)
   1716  1.1  mrg ===========================
   1717  1.1  mrg Time passes, a few more bugs have crept out of the woodwork that are a
   1718  1.1  mrg compelling reason to update.
   1719  1.1  mrg 
   1720  1.1  mrg Bugs fixed in this release (compared to 2.17.0)
   1721  1.1  mrg -----------------------------------------------
   1722  1.1  mrg 
   1723  1.1  mrg * Limit maximum object size so that all of the source, mask and
   1724  1.1  mrg   destination can be mapped into the aperture simultaneously by basing the
   1725  1.1  mrg   limit on the mappable aperture size rather than the size of the total
   1726  1.1  mrg   GATT.
   1727  1.1  mrg 
   1728  1.1  mrg * Incorrect clipping of polygons
   1729  1.1  mrg   https://bugs.freedesktop.org/show_bug.cgi?id=43649
   1730  1.1  mrg   Regression from 2.15.901
   1731  1.1  mrg 
   1732  1.1  mrg * Limit number of VMA cached to avoid hitting the per-process VMA limit
   1733  1.1  mrg   There still is a residual bug in that we seem to have so many objects
   1734  1.1  mrg   floating around in the first place and that still leads to exhaustion
   1735  1.1  mrg   of system limits.
   1736  1.1  mrg   https://bugs.freedesktop.org/show_bug.cgi?id=43075
   1737  1.1  mrg   https://bugs.freedesktop.org/show_bug.cgi?id=40066
   1738  1.1  mrg 
   1739  1.1  mrg * Latency in processing user-input during continuous rendering
   1740  1.1  mrg 
   1741  1.1  mrg Release 2.17.0 (2011-11-16)
   1742  1.1  mrg ==============================
   1743  1.1  mrg A few months have passed, and we have accumulated a surprising number of
   1744  1.1  mrg bug fixes. Oops! We would strongly encourage everyone to upgrade.
   1745  1.1  mrg 
   1746  1.1  mrg Bugs fixed in this snapshot (compared to 2.16.902)
   1747  1.1  mrg --------------------------------------------------
   1748  1.1  mrg 
   1749  1.1  mrg * Video clobbering composite batch state
   1750  1.1  mrg   http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=635953
   1751  1.1  mrg 
   1752  1.1  mrg Snapshot 2.16.902 (2011-11-13)
   1753  1.1  mrg ==============================
   1754  1.1  mrg This is the second release candidate in preparation for the upcoming
   1755  1.1  mrg 2.17.0 release. We will appreciate any feedback we can get from
   1756  1.1  mrg testing of this snapshot, and thanks to everyone who tested and reported
   1757  1.1  mrg upon issues in the last snapshot.
   1758  1.1  mrg

   1798  1.1  mrg ==============================
   1799  1.1  mrg A new quarter, a new release! The key feature of this release, looking past
   1800  1.1  mrg the bug fixes, is the enabling of IvyBridge acceleration. We have also fixed
   1801  1.1  mrg many bugs and graphical glitches and would encourage everyone to upgrade.

   1811  1.1  mrg 2.16.0 release. We will appreciate any feedback we can get from
   1812  1.1  mrg testing of this snapshot.
   1813  1.1  mrg 
   1814  1.1  mrg The highlight of this snapshot is the full enabling of IvyBridge with
   1815  1.1  mrg acceleration for Render and Xv, along with handling of the shared render
   1816  1.1  mrg buffer allocations required for Mesa. Also of note is that deep-color
   1817  1.1  mrg support is enabled (for all chipsets), which allows you to drive your
   1818  1.1  mrg 30-bit monitor at its native colour depth.

   1839  1.1  mrg ==============================
   1840  1.1  mrg We are pleased to announce this major release of the xf86-video-intel
   1841  1.1  mrg driver, roughly on schedule at 3 months since 2.14.0. With the many bug
   1842  1.1  mrg fixes in this release, we encourage everyone to upgrade to 2.15.
   1843  1.1  mrg 
   1844  1.1  mrg The priority for this quarter has been simply to be unexciting and stabilise
   1845  1.1  mrg the driver further, seeking to capitalise upon the improvements elsewhere
   1846  1.1  mrg in the stack.
   1847  1.1  mrg

   1849  1.1  mrg --------------------------------------------------
   1850  1.1  mrg 
   1851  1.1  mrg * Turn off relaxed fencing by default for older chipsets
   1852  1.1  mrg   This was continuing to destabilize those system, so for the release
   1853  1.1  mrg   we disabled the feature. If you wish to help us debug this, you can
   1854  1.1  mrg   re-enable the optimisation with Option "RelaxedFencing" "True".

   1867  1.1  mrg This is the third release candidate in preparation for the upcoming
   1868  1.1  mrg 2.15.0 release. We will appreciate any feedback we can get from
   1869  1.1  mrg testing of this snapshot.
   1870  1.1  mrg 
   1871  1.1  mrg There was a bit of churn since 2.14.902 as a potential fix for a
   1872  1.1  mrg performance regression was tried but had to reverted when it was found to
   1873  1.1  mrg cause glitches running Compiz on SandyBridge. Otherwise, there were just a
   1874  1.1  mrg couple of fixes for building against old xservers and running on an
   1875  1.1  mrg obscure chipset.
   1876  1.1  mrg

   1917  1.1  mrg 
   1918  1.1  mrg Still no further along my grandiose plans to improve Render performance,
   1919  1.1  mrg aside from the performance tuning lower in the stack, instead we have had
   1920  1.1  mrg a steady stream of bug fixes.

   1944  1.1  mrg ===========================
   1945  1.1  mrg We are pleased to announce this major release of the xf86-video-intel
   1946  1.1  mrg driver, on schedule at 3 months since 2.13.0. With the many bug fixes
   1947  1.1  mrg in this release, we encourage everyone to upgrade to 2.14.
   1948  1.1  mrg 
   1949  1.1  mrg The most notable feature of this release is the inclusion of acceleration
   1950  1.1  mrg support, both RENDER and XVIDEO, for Sandy Bridge; note that this requires
   1951  1.1  mrg a 2.6.37 kernel. In improving the acceleration code paths to support Sandy
   1952  1.1  mrg Bridge, we were also able to improve the performance of the general i965+
   1953  1.1  mrg RENDER acceleration. For example on i3, glyph (aa10 and rgb10) performance
   1954  1.1  mrg is about 3x faster, as is performing small copies between windows, with the
   1955  1.1  mrg improvement becoming negligible once you hit around 100 pixels square.

   1960  1.1  mrg This is the second release candidate in preparation for the upcoming
   1961  1.1  mrg 2.14.0 release, and if no showstoppers turn up in wider testing will
   1962  1.1  mrg become the next release. Besides the usual bug fixes, we've included
   1963  1.1  mrg patches by Mario Kleiner to improve vblank handing which both improve the
   1964  1.1  mrg timing accuracy and remove a few potential races -- provided you also
   1965  1.1  mrg have the corresponding fixes in the kernel.

   1986  1.1  mrg Improving the code base for Sandybridge should also have had knock

   2291  1.1  mrg ===========================
   2292  1.1  mrg New in 2.11: DRI2 and page flipping
   2293  1.1  mrg -----------------------------------
   2294  1.1  mrg The most significant new feature of this release is support for new
   2295  1.1  mrg DRI2 APIs, allowing page flipping to occur for swaps that are
   2296  1.1  mrg full-screen and not rotated.
   2297  1.1  mrg 
   2298  1.1  mrg Performance improvements in 2.11 compared to 2.10

   2300  1.1  mrg Dramatically improved performance of large pixmaps on
   2301  1.1  mrg memory-constrained hardware, (such as 945), by using tiling.
   2302  1.1  mrg Note that this fix is new since the most recent release
   2303  1.1  mrg candidate for this release (2.10.903).
   2304  1.1  mrg 
   2305  1.1  mrg     https://bugs.freedesktop.org/show_bug.cgi?id=25375
   2306  1.1  mrg 
   2307  1.1  mrg Elimination of software fallback with alpha-only pixmap (a fix which
   2308  1.1  mrg eliminated a full second from the Moblin boot time):
   2309  1.1  mrg 
   2310  1.1  mrg     https://bugs.freedesktop.org/show_bug.cgi?id=26189
   2311  1.1  mrg 
   2312  1.1  mrg Notable bug fixes in 2.11 compared to 2.10
   2313  1.1  mrg ------------------------------------------
   2314  1.1  mrg Fix for undesired black borders on some images, (caued several
   2315  1.1  mrg problems with firefox):
   2316  1.1  mrg 
   2317  1.1  mrg     http://bugs.freedesktop.org/show_bug.cgi?id=17933
   2318  1.1  mrg 
   2319  1.1  mrg And other fixes to provide more conformance with existing
   2320  1.1  mrg software-rendering, (as measures by the cairo test suite), such as the
   2321  1.1  mrg sampling location for nearest-neighbor sampling.
   2322  1.1  mrg 
   2323  1.1  mrg Other changes
   2324  1.1  mrg -------------
   2325  1.1  mrg Eric Anholt and Daniel Vetter both removed large piles of old and
   2326  1.1  mrg useless code now that the driver requires kernel modesetting
   2327  1.1  mrg (KMS). This continues to reduce the mainteance burden of the driver,
   2328  1.1  mrg making it easier to isolate and fix bugs.

   2361  1.1  mrg ==============================
   2362  1.1  mrg Some significant bug fixes
   2363  1.1  mrg --------------------------
   2364  1.1  mrg Fix video color problems due to YUV plane ordering issue. This fixed a
   2365  1.1  mrg regression that showed up recently (only in these release candidates).
   2366  1.1  mrg 
   2367  1.1  mrg Fix recent regression leading to corruption under compiz:

   2369  1.1  mrg   https://bugs.freedesktop.org/show_bug.cgi?id=26814
   2370  1.1  mrg 
   2371  1.1  mrg Further DRI2 improvements/fixes from Mario Kleiner and Jesse Barnes,
   2372  1.1  mrg (including support for SwapBuffers request with divisor != 0).
   2373  1.1  mrg 
   2374  1.1  mrg Fix build against X server 1.6 branch.
   2375  1.1  mrg 
   2376  1.1  mrg Avoid flooding logs after an error occurs.
   2377  1.1  mrg 
   2378  1.1  mrg And dramatic code cleanups
   2379  1.1  mrg --------------------------
   2380  1.1  mrg Eric Anholt removed several cases of old, useless code, (conditions
   2381  1.1  mrg that could not occur now that we require KMS, etc.).
   2382  1.1  mrg 
   2383  1.1  mrg Daniel Vetter eliminated piles of code by modernizing the XvMC
   2384  1.1  mrg memory-management and completely removing the old i830_memory
   2385  1.1  mrg allocator (i830_allocate_memory, i830_free_memory), etc.
   2386  1.1  mrg 
   2387  1.1  mrg Snapshot 2.10.901 (2010-02-26)
   2388  1.1  mrg ==============================
   2389  1.1  mrg The most significant new feature of this release is support for new
   2390  1.1  mrg DRI2 APIs, allowing page flipping to occur for swaps that are
   2391  1.1  mrg full-screen and not rotated.
   2392  1.1  mrg 
   2393  1.1  mrg Some significant bug fixes
   2394  1.1  mrg --------------------------
   2395  1.1  mrg * Avoid fallback due to failing to extract pixel value from an
   2396  1.1  mrg   alpha-only solid, (this fix eliminated 1 second from Mobilin boot
   2397  1.1  mrg   time).
   2398  1.1  mrg 
   2399  1.1  mrg   https://bugs.freedesktop.org/show_bug.cgi?id=26189
   2400  1.1  mrg 
   2401  1.1  mrg * Handle full-height blits without tearing in CopyRegion
   2402  1.1  mrg 
   2403  1.1  mrg   https://bugs.freedesktop.org/show_bug.cgi?id=22475
   2404  1.1  mrg 
   2405  1.1  mrg Several other fixes and cleanups are included as well, (including the
   2406  1.1  mrg removal of stale utility code that is now maintained in the separate
   2407  1.1  mrg intel-gpu-tools module).
   2408  1.1  mrg 
   2409  1.1  mrg Release 2.10.0 (2010-01-04)
   2410  1.1  mrg ===========================
   2411  1.1  mrg New requirements of 2.10 compared to 2.9
   2412  1.1  mrg ----------------------------------------
   2413  1.1  mrg  * Linux kernel with kernel-modesetting (KMS)
   2414  1.1  mrg 
   2415  1.1  mrg    All user-modesetting code has now been removed from the driver.
   2416  1.1  mrg    We highly recommend kernel version 2.6.32 or later.
   2417  1.1  mrg 
   2418  1.1  mrg  * Libdrm >= 2.4.16
   2419  1.1  mrg 
   2420  1.1  mrg New features in 2.10 compared to 2.9
   2421  1.1  mrg ------------------------------------
   2422  1.1  mrg  * New driver debugging options available in xorg.conf
   2423  1.1  mrg    (DebugFlushBatches, DebugFlushCaches, DebugWait). See "man intel"
   2424  1.1  mrg    for more details.
   2425  1.1  mrg 
   2426  1.1  mrg  * Video overlay support with KMS. This currently requires Linux
   2427  1.1  mrg    2.6.33, but a backport to 2.6.32 is available here:
   2428  1.1  mrg 
   2429  1.1  mrg    http://gitorious.org/daniel-s-linux-stuff/linux-kernel/commits/intel-kms-overlay-for-2.6.32
   2430  1.1  mrg 
   2431  1.1  mrg Notable fixes in 2.10 compared to 2.9
   2432  1.1  mrg -----------------------------------
   2433  1.1  mrg  * Fix crash when XRenderComposite is called with a -1 value for
   2434  1.1  mrg    width/height, (crash at login when using compiz).
   2435  1.1  mrg 
   2436  1.1  mrg    http://bugs.freedesktop.org/show_bug.cgi?id=24724
   2437  1.1  mrg 
   2438  1.1  mrg  * Fix to support larger extended desktops, (such as a 2560x1600 plus a
   2439  1.1  mrg    1920x1200 monitor).
   2440  1.1  mrg 
   2441  1.1  mrg 
   2442  1.1  mrg  * Fix glyph corruption due to insufficient cache flushing:
   2443  1.1  mrg 
   2444  1.1  mrg    https://bugs.freedesktop.org/show_bug.cgi?id=24315
   2445  1.1  mrg 
   2446  1.1  mrg Several other correctness and performance fixes are also included.
   2447  1.1  mrg 
   2448  1.1  mrg Note: The driver code of the 2.10.0 release is identical to that of
   2449  1.1  mrg the 2.9.99.901 release candidate. The only changes in 2.10.0 compared
   2450  1.1  mrg to 2.9.99.902 are a minor change to the configure script, and some
   2451  1.1  mrg small updates to the documentation.
   2452  1.1  mrg 
   2453  1.1  mrg Snapshot 2.9.99.902 (2009-12-10)
   2454  1.1  mrg ================================
   2455  1.1  mrg This is the second release candidate in preparation for the upcoming
   2456  1.1  mrg 2.10.0 release. We will appreciate any feedback we can get from
   2457  1.1  mrg testing of this snapshot to improve the 2.10.0 release.
   2458  1.1  mrg 
   2459  1.1  mrg Compared to the previous snapshot, this snapshot now correctly
   2460  1.1  mrg verifies that libdrm 2.4.16 (or newer) is available. The previous
   2461  1.1  mrg snapshot also required libdrm 2.4.16 for correct functionality, but
   2462  1.1  mrg neglected to notify the user of this at configure, compile, or install
   2463  1.1  mrg time and would instead simply fail to run.
   2464  1.1  mrg 
   2465  1.1  mrg Snapshot 2.9.99.901 (2009-11-30)
   2466  1.1  mrg ================================
   2467  1.1  mrg This is the first release candidate in preparation for the upcoming
   2468  1.1  mrg 2.10.0 release. We will appreciate any feedback we can get from
   2469  1.1  mrg testing of this snapshot to improve the 2.10.0 release.
   2470  1.1  mrg 
   2471  1.1  mrg With this snapshot, the xf86-video-intel driver requires kernel
   2472  1.1  mrg modesetting (KMS) as all of the user modesetting (UMS) support has
   2473  1.1  mrg been removed from the driver.
   2474  1.1  mrg 
   2475  1.1  mrg Release 2.9.0 (2009-09-28)
   2476  1.1  mrg ==========================
   2477  1.1  mrg We are pleased to announce the 2.9.0 release of the xf86-video-intel
   2478  1.1  mrg driver. (If you have been following along at home, this release is
   2479  1.1  mrg identical to the 2.8.99.902 release candidate other than the version
   2480  1.1  mrg number).
   2481  1.1  mrg 
   2482  1.1  mrg New features in 2.9 compared to 2.8
   2483  1.1  mrg -----------------------------------
   2484  1.1  mrg * Support for the B43 chipset.
   2485  1.1  mrg 
   2486  1.1  mrg Major fixes in 2.9.0 compared to 2.8.0
   2487  1.1  mrg --------------------------------------
   2488  1.1  mrg * Multiple fixes to make the driver stable for 8xx chipsets, (855GM,
   2489  1.1  mrg   865G, etc.). The 2.8 driver series was extremely unstable with many
   2490  1.1  mrg   of these chipsets.
   2491  1.1  mrg 
   2492  1.1  mrg   https://bugs.freedesktop.org/show_bug.cgi?id=22904 (and many duplicates)
   2493  1.1  mrg   https://bugs.freedesktop.org/show_bug.cgi?id=22947
   2494  1.1  mrg 
   2495  1.1  mrg * Add support for BACKLIGHT property when using kernel modesetting
   2496  1.1  mrg   (KMS). This allows backlight adjustment with programs such as
   2497  1.1  mrg   "xbacklight -set <percentage>" or "xrandr --set BACKLIGHT <value>".
   2498  1.1  mrg 
   2499  1.1  mrg   https://bugs.freedesktop.org/show_bug.cgi?id=20963
   2500  1.1  mrg 
   2501  1.1  mrg * Fix so that "xrandr --scale" works when using KMS.
   2502  1.1  mrg 
   2503  1.1  mrg   https://bugs.freedesktop.org/show_bug.cgi?id=22893
   2504  1.1  mrg 
   2505  1.1  mrg * Fix segfaults of X server when logging out.
   2506  1.1  mrg 
   2507  1.1  mrg   https://bugs.freedesktop.org/show_bug.cgi?id=20516
   2508  1.1  mrg 
   2509  1.1  mrg * Avoid falling back to software for 1-bit alpha-only masks.
   2510  1.1  mrg 
   2511  1.1  mrg   https://bugs.freedesktop.org/show_bug.cgi?id=23184
   2512  1.1  mrg 
   2513  1.1  mrg * Fix pixel sampling position for 8xx chipsets, (fixes some cairo-test
   2514  1.1  mrg   suite failures).
   2515  1.1  mrg 
   2516  1.1  mrg Snapshot 2.8.99.901 (2009-09-09)
   2517  1.1  mrg ================================
   2518  1.1  mrg This is the first release candidate in preparation for the upcoming
   2519  1.1  mrg 2.9.0 release. We will appreciate any feedback we can get from testing
   2520  1.1  mrg of this snapshot to improve the 2.9.0 release.
   2521  1.1  mrg 
   2522  1.1  mrg See the commit log for changes in this release, and developers, please
   2523  1.1  mrg provide me summaries for any major features in this release that you
   2524  1.1  mrg think should appear in NEWS and in the 2.9.0 release notes.
   2525  1.1  mrg 
   2526  1.1  mrg Note: We are still investigating failures with 865G chipsets, (these
   2527  1.1  mrg failures existed in the 2.8 series as well). We are hoping to fix
   2528  1.1  mrg these failures before the 2.9.0 release.
   2529  1.1  mrg 
   2530  1.1  mrg Release 2.8.0 (2009-07-20)
   2531  1.1  mrg ==========================
   2532  1.1  mrg We are pleased to present this major release of the xf86-video-intel
   2533  1.1  mrg driver. This release is very similar to the 2.7.99.902 release
   2534  1.1  mrg candidate but includes a couple of additional bug fixes, (for bugs
   2535  1.1  mrg #22760 and @22483).
   2536  1.1  mrg 
   2537  1.1  mrg Compared to the 2.7 releases this driver contains several new features
   2538  1.1  mrg and many bug fixes. The driver now depends on X server 1.6 or later,
   2539  1.1  mrg and eliminates several obsolete code paths, (XAA and EXA removed in
   2540  1.1  mrg favor of UXA, DRI1 support eliminated). The driver certainly will work
   2541  1.1  mrg best with an i915 module from a recent kernel (2.6.31) and with
   2542  1.1  mrg kernel-modesetting (KMS, specified by loading i915 with the option
   2543  1.1  mrg "modeset=1").
   2544  1.1  mrg 
   2545  1.1  mrg New features in 2.8.0 compared to 2.7
   2546  1.1  mrg -------------------------------------
   2547  1.1  mrg * Remove XAA/EXA/DRI1 and NoAccel, and only support UXA/DRI2 now
   2548  1.1  mrg   (requiring xserver 1.6).
   2549  1.1  mrg 
   2550  1.1  mrg * VLD support added into XvMC for Mpeg2, which decreases CPU usage
   2551  1.1  mrg   when playing video.
   2552  1.1  mrg 
   2553  1.1  mrg Major fixes in 2.8.0 compared to 2.7
   2554  1.1  mrg ------------------------------------
   2555  1.1  mrg * Fix broken front-buffer rendering
   2556  1.1  mrg   https://bugs.freedesktop.org/show_bug.cgi?id=19174
   2557  1.1  mrg 
   2558  1.1  mrg * Fix disabling of XvMC disabled
   2559  1.1  mrg   https://bugs.freedesktop.org/show_bug.cgi?id=20790
   2560  1.1  mrg 
   2561  1.1  mrg * Fix broken VT switch on some machines
   2562  1.1  mrg   https://bugs.freedesktop.org/show_bug.cgi?id=19578
   2563  1.1  mrg 
   2564  1.1  mrg * Improve performance of trapezoid rendering for UXA
   2565  1.1  mrg   https://bugs.freedesktop.org/show_bug.cgi?id=21376
   2566  1.1  mrg 
   2567  1.1  mrg * Vblank sync'd GL buffer swap (fixing video tearing under composite)
   2568  1.1  mrg   https://bugs.freedesktop.org/show_bug.cgi?id=20664
   2569  1.1  mrg 
   2570  1.1  mrg * Fix G41 DRM support
   2571  1.1  mrg   https://bugs.freedesktop.org/show_bug.cgi?id=21095
   2572  1.1  mrg 
   2573  1.1  mrg * Fix crash on some 8xx
   2574  1.1  mrg   https://bugs.freedesktop.org/show_bug.cgi?id=18974
   2575  1.1  mrg 
   2576  1.1  mrg Various fixes for GPU hangs, and more...
   2577  1.1  mrg 
   2578  1.1  mrg Snapshot 2.7.99.902 (2009-07-13)
   2579  1.1  mrg --------------------------------
   2580  1.1  mrg This is the first release candidate in preparation for the upcoming
   2581  1.1  mrg 2.8.0 release. Most major and critical bugs should be fixed, but some
   2582  1.1  mrg minor bugs may still be present. We will appreciate any feedback we
   2583  1.1  mrg can get from testing of this snapshot to improve the 2.8.0 release.
   2584  1.1  mrg 
   2585  1.1  mrg Snapshot 2.7.99.901 (2009-06-10)
   2586  1.1  mrg --------------------------------
   2587  1.1  mrg This is the first release candidate in preparation for the upcoming
   2588  1.1  mrg 2.8.0 release. Most critical bugs should be fixed, but some major
   2589  1.1  mrg bugs may still be present. We will appreciate any feedback we can
   2590  1.1  mrg get from testing of this snapshot to improve the 2.8.0 release.
   2591  1.1  mrg 
   2592  1.1  mrg Some of the major fixes in this snapshot include:
   2593  1.1  mrg 
   2594  1.1  mrg 	* Several fixes for intermittent GPU hangs/crashes, (some of
   2595  1.1  mrg 	  which already appeared in the 2.7.1 release)
   2596  1.1  mrg 
   2597  1.1  mrg 	* Fix to avoid X crash when viewing large images in browser
   2598  1.1  mrg 
   2599  1.1  mrg 	* Fix X server failure when running old (non-GEM) kernel
   2600  1.1  mrg 
   2601  1.1  mrg 	* Fixes for SDVO LVDS mode detection
   2602  1.1  mrg 
   2603  1.1  mrg 	* Fix major performance regression of trapezoid rendering
   2604  1.1  mrg           compared to XAA/EXA
   2605  1.1  mrg 
   2606  1.1  mrg 	* New support for tear-free video when using KMS
   2607  1.1  mrg 
   2608  1.1  mrg 	* New support for tear-free DRI2 CopyRegion
   2609  1.1  mrg 
   2610  1.1  mrg Snapshot 2.7.99.1 (2009-04-28)
   2611  1.1  mrg ------------------------------
   2612  1.1  mrg This is a development snapshot very early in the process toward
   2613  1.1  mrg developing 2.8. There have been some big changes to the code, and
   2614  1.1  mrg we're anxious to get feedback on these changes as early as possible.
   2615  1.1  mrg 
   2616  1.1  mrg Here is a summary of the biggest changes:
   2617  1.1  mrg 
   2618  1.1  mrg   * Driver now depends on X server 1.6 or later
   2619  1.1  mrg 
   2620  1.1  mrg   * Eliminate XAA and EXA support (in favor of UXA)
   2621  1.1  mrg 
   2622  1.1  mrg   * Eliminate DRI1 support
   2623  1.1  mrg 
   2624  1.1  mrg   * Fixes for running without DRI at all
   2625  1.1  mrg 
   2626  1.1  mrg These code removals represent a deletion of a substantial amount of
   2627  1.1  mrg code, (and hopefully piles of bugs), as well as reduce the maintenance
   2628  1.1  mrg effort going forward as the number of combinatorial configurations for
   2629  1.1  mrg the driver are greatly reduced. This means that users are much more
   2630  1.1  mrg likely to be running code that has actually been tested, and it will
   2631  1.1  mrg be much easy for developers to replicate bugs that users experience.
   2632  1.1  mrg 
   2633  1.1  mrg One of the things that would be most useful in testing this release is
   2634  1.1  mrg to revisit any outstanding bugs that you have previously reported. If
   2635  1.1  mrg the buggy behavior is gone, (or the bug is no longer relevant---such
   2636  1.1  mrg as a bug that's specific to XAA only), please feel free to indicate so
   2637  1.1  mrg in bugzilla or even just close the bug.
   2638  1.1  mrg 
   2639  1.1  mrg If you confirm that the bug is still present, please indicate so in
   2640  1.1  mrg the bug report. (I was going to ask that you select a 1.7.99 version,
   2641  1.1  mrg but it looks like bugzilla only has versions for products not
   2642  1.1  mrg compoenents, while we use a "xorg" product and a "driver/intel"
   2643  1.1  mrg component.) We definitely want to make any such confirmed bugs a

   2649  1.1  mrg Release 2.7.0 (2009-04-15)
   2650  1.1  mrg --------------------------
   2651  1.1  mrg Compared to the 2.6 series, 2.7.0 has a large number of bug fixes, but
   2652  1.1  mrg also a few significant features, such as:
   2653  1.1  mrg 
   2654  1.1  mrg         SDVO-TV support, available on ADD2 card (bug#9992) and
   2655  1.1  mrg         D945GCLF2 board (bug#17776).
   2656  1.1  mrg 
   2657  1.1  mrg         Basic SDVO-LVDS support
   2658  1.1  mrg 
   2659  1.1  mrg         XV video display without tearing
   2660  1.1  mrg 	[Though this isn't working for all users yet, see
   2661  1.1  mrg 	https://bugs.freedesktop.org/show_bug.cgi?id=21076 ]
   2662  1.1  mrg 
   2663  1.1  mrg 	Various fixes for UXA, DRI2, and Kernel modesetting.
   2664  1.1  mrg 
   2665  1.1  mrg We encourage users to use kernel modesetting and UXA acceleration with
   2666  1.1  mrg this release, which should give the best performance and
   2667  1.1  mrg robustness. When KMS is available, UXA is the default acceleration
   2668  1.1  mrg used by the driver, (EXA is the default otherwise).
   2669  1.1  mrg 
   2670  1.1  mrg Known issue:
   2671  1.1  mrg 
   2672  1.1  mrg 	Some Linux kernel versions (such as 2.6.29) are known to have
   2673  1.1  mrg 	broken PAT code that causes recent versions of this driver to
   2674  1.1  mrg 	fail, (which can manifest as the X server simply not
   2675  1.1  mrg 	starting). This can be verified by adding the "nopat" option
   2676  1.1  mrg 	to the kernel command-line and seeing the failure go away. We
   2677  1.1  mrg 	hope that newer kernels in the 2.6.29.x as well as 2.6.30 and
   2678  1.1  mrg 	above will have working PAT code.
   2679  1.1  mrg 
   2680  1.1  mrg Some of the most notable bugs fixed in 2.7.0 include:
