Release 2.8.0 (2009-07-20) ========================== We are pleased to present this major release of the xf86-video-intel driver. This release is very similar to the 2.7.99.902 release candidate but includes a couple of additional bug fixes, (for bugs #22760 and @22483). Compared to the 2.7 releases this driver contains several new features and many bug fixes. The driver now depends on X server 1.6 or later, and eliminates several obsolete code paths, (XAA and EXA removed in favor of UXA, DRI1 support eliminated). The driver certainly will work best with an i915 module from a recent kernel (2.6.31) and with kernel-modesetting (KMS, specified by loading i915 with the option "modeset=1"). New features in 2.8.0 compared to 2.7 ------------------------------------- * Remove XAA/EXA/DRI1 and NoAccel, and only support UXA/DRI2 now (requiring xserver 1.6). * VLD support added into XvMC for Mpeg2, which decreases CPU usage when playing video. Major fixes in 2.8.0 compared to 2.7 ------------------------------------ * Fix broken front-buffer rendering https://bugs.freedesktop.org/show_bug.cgi?id=19174 * Fix disabling of XvMC disabled https://bugs.freedesktop.org/show_bug.cgi?id=20790 * Fix broken VT switch on some machines https://bugs.freedesktop.org/show_bug.cgi?id=19578 * Improve performance of trapezoid rendering for UXA https://bugs.freedesktop.org/show_bug.cgi?id=21376 * Vblank sync'd GL buffer swap (fixing video tearing under composite) https://bugs.freedesktop.org/show_bug.cgi?id=20664 * Fix G41 DRM support https://bugs.freedesktop.org/show_bug.cgi?id=21095 * Fix crash on some 8xx https://bugs.freedesktop.org/show_bug.cgi?id=18974 Various fixes for GPU hangs, and more... Snapshot 2.7.99.902 (2009-07-13) -------------------------------- This is the first release candidate in preparation for the upcoming 2.8.0 release. Most major and critical bugs should be fixed, but some minor bugs may still be present. We will appreciate any feedback we can get from testing of this snapshot to improve the 2.8.0 release. Snapshot 2.7.99.901 (2009-06-10) -------------------------------- This is the first release candidate in preparation for the upcoming 2.8.0 release. Most critical bugs should be fixed, but some major bugs may still be present. We will appreciate any feedback we can get from testing of this snapshot to improve the 2.8.0 release. Some of the major fixes in this snapshot include: * Several fixes for intermittent GPU hangs/crashes, (some of which already appeared in the 2.7.1 release) * Fix to avoid X crash when viewing large images in browser * Fix X server failure when running old (non-GEM) kernel * Fixes for SDVO LVDS mode detection * Fix major performance regression of trapezoid rendering compared to XAA/EXA * New support for tear-free video when using KMS * New support for tear-free DRI2 CopyRegion Snapshot 2.7.99.1 (2009-04-28) ------------------------------ This is a development snapshot very early in the process toward developing 2.8. There have been some big changes to the code, and we're anxious to get feedback on these changes as early as possible. Here is a summary of the biggest changes: * Driver now depends on X server 1.6 or later * Eliminate XAA and EXA support (in favor of UXA) * Eliminate DRI1 support * Fixes for running without DRI at all These code removals represent a deletion of a substantial amount of code, (and hopefully piles of bugs), as well as reduce the maintenance effort going forward as the number of combinatorial configurations for the driver are greatly reduced. This means that users are much more likely to be running code that has actually been tested, and it will be much easy for developers to replicate bugs that users experience. One of the things that would be most useful in testing this release is to revisit any outstanding bugs that you have previously reported. If the buggy behavior is gone, (or the bug is no longer relevant---such as a bug that's specific to XAA only), please feel free to indicate so in bugzilla or even just close the bug. If you confirm that the bug is still present, please indicate so in the bug report. (I was going to ask that you select a 1.7.99 version, but it looks like bugzilla only has versions for products not compoenents, while we use a "xorg" product and a "driver/intel" component.) We definitely want to make any such confirmed bugs a priority, so it would be nice to have a consistent mechanism to search for these bugs. Suggestions are welcome on the best approach. Thanks in advance for any testing or feedback on this snapshot. Release 2.7.0 (2009-04-15) -------------------------- Compared to the 2.6 series, 2.7.0 has a large number of bug fixes, but also a few significant features, such as: SDVO-TV support, available on ADD2 card (bug#9992) and D945GCLF2 board (bug#17776). Basic SDVO-LVDS support XV video display without tearing [Though this isn't working for all users yet, see https://bugs.freedesktop.org/show_bug.cgi?id=21076 ] Various fixes for UXA, DRI2, and Kernel modesetting. We encourage users to use kernel modesetting and UXA acceleration with this release, which should give the best performance and robustness. When KMS is available, UXA is the default acceleration used by the driver, (EXA is the default otherwise). Known issue: Some Linux kernel versions (such as 2.6.29) are known to have broken PAT code that causes recent versions of this driver to fail, (which can manifest as the X server simply not starting). This can be verified by adding the "nopat" option to the kernel command-line and seeing the failure go away. We hope that newer kernels in the 2.6.29.x as well as 2.6.30 and above will have working PAT code. Some of the most notable bugs fixed in 2.7.0 include: [GM45 965GM] bad htotal causes panel startup failure https://bugs.freedesktop.org/show_bug.cgi?id=17292 [xrandr TV] need TV output property control https://bugs.freedesktop.org/show_bug.cgi?id=12763 [TV] "xrandr --set TV_FORMAT" gets BadMatch error https://bugs.freedesktop.org/show_bug.cgi?id=16566 [945 tiling] Low performance due to no A17 workaround https://bugs.freedesktop.org/show_bug.cgi?id=16835 [TV]Flicker when launching applications in the 2.4-branch https://bugs.freedesktop.org/show_bug.cgi?id=17405 [945GM FBC] FBC causes underruns & flicker https://bugs.freedesktop.org/show_bug.cgi?id=18651 [xv] Textured video suffers from tearing https://bugs.freedesktop.org/show_bug.cgi?id=19635 [G45] Random hangs with UXA https://bugs.freedesktop.org/show_bug.cgi?id=19734 [945GM] Any 3D app is slow in resolution higher than 800x600 with UXA+DRI2, due to tiling https://bugs.freedesktop.org/show_bug.cgi?id=19738 [i915 UXA,EXA] rotation messes display with tiling on https://bugs.freedesktop.org/show_bug.cgi?id=20265 [G45] DRI2/UXA gives solid white instead of transparency https://bugs.freedesktop.org/show_bug.cgi?id=20321 LVDS output not detected https://bugs.freedesktop.org/show_bug.cgi?id=20517 xf86-video-intel-2.6.3: Xv crashes X server https://bugs.freedesktop.org/show_bug.cgi?id=20525 [G965 non-GEM] systray in KDE 4 completely broken https://bugs.freedesktop.org/show_bug.cgi?id=20527 [SDVO-TV]the desktop is teared in four sections on the screen https://bugs.freedesktop.org/show_bug.cgi?id=20550 Intel video driver 2.6.3 crashes with XVideo https://bugs.freedesktop.org/show_bug.cgi?id=20563 [855GM] Xv crash with non-KMS https://bugs.freedesktop.org/show_bug.cgi?id=20585 2.6.99.902 breaks native 1680x1050 mode on TMDS -- EDID miss https://bugs.freedesktop.org/show_bug.cgi?id=20594 [945GM TV] 2.6.99.902 sets a too high CONTRAST-value https://bugs.freedesktop.org/show_bug.cgi?id=20670 [915GM] fail to detect LVDS with new VBT code https://bugs.freedesktop.org/show_bug.cgi?id=20752 [regression i965]tiled output when start X https://bugs.freedesktop.org/show_bug.cgi?id=20803 2.6.99.902: LVDS wrongly detected as disconnected https://bugs.freedesktop.org/show_bug.cgi?id=20826 vt switching fails and crashes X https://bugs.freedesktop.org/show_bug.cgi?id=20863 [HDMI] The screen will flicker when some application runs on G45-64 https://bugs.freedesktop.org/show_bug.cgi?id=20875 TexturedVideo is offsetted wrongly on dualhead https://bugs.freedesktop.org/show_bug.cgi?id=20980 [EXA] xvideo hang X https://bugs.freedesktop.org/show_bug.cgi?id=21027 [EXA] x11perf performance regression https://bugs.freedesktop.org/show_bug.cgi?id=21029 And many others...
