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 777 1.1 mrg * Add a GPU flush before changing blend modes on Ironlake 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 790 1.1 mrg https://bugs.freedesktop.org/show_bug.cgi?id=66168 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] 799 1.1 mrg https://bugs.freedesktop.org/show_bug.cgi?id=66297 800 1.1 mrg 801 1.1 mrg Also fixed this week was: 802 1.1 mrg 803 1.1 mrg commit 22fd5ca947b58901927d100d2b1aa0f1672b3435 804 1.1 mrg Author: Chris Wilson <chris (a] chris-wilson.co.uk> 805 1.1 mrg Date: Fri Jun 28 16:54:08 2013 +0100 806 1.1 mrg 807 1.1 mrg drm/i915: Only clear write-domains after a successful wait-seqno 808 1.1 mrg 809 1.1 mrg which affects kernels 3.7 - 3.10, coming to a stable kernel near you soon. 810 1.1 mrg 811 1.1 mrg 812 1.1 mrg Release 2.21.10 (2013-06-22) 813 1.1 mrg ============================ 814 1.1 mrg Fixes missing support for Xv (with the textured video adaptor) on 815 1.1 mrg Haswell, and an old bug with wide monitors on various generation.

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. 890 1.1 mrg 891 1.1 mrg * Allow XvMC to also target overlay/sprite planes. 892 1.1 mrg 893 1.1 mrg * Throw in a paranoid MI_FLUSH between BLT and RENDER operations on 894 1.1 mrg Ironlake. 895 1.1 mrg https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1168066 896 1.1 mrg 897 1.1 mrg * Prevent reuse of old framebuffers after a resize. 898 1.1 mrg https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1157678 899 1.1 mrg 900 1.1 mrg * Fix compilation with --enable-valgrind and no --enable-debug 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. 905 1.1 mrg https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1178020 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.

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.

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.

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 1222 1.1 mrg https://bugs.freedesktop.org/show_bug.cgi?id=26345 1223 1.1 mrg 1224 1.1 mrg 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.

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).

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.

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. 1956 1.1 mrg 1957 1.1 mrg 1958 1.1 mrg Snapshot 2.13.903 (2010-01-04) 1959 1.1 mrg ============================== 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.

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 2644 1.1 mrg priority, so it would be nice to have a consistent mechanism to search 2645 1.1 mrg for these bugs. Suggestions are welcome on the best approach. 2646 1.1 mrg 2647 1.1 mrg Thanks in advance for any testing or feedback on this snapshot. 2648 1.1 mrg 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: 2681 1.1 mrg 2682 1.1 mrg [GM45 965GM] bad htotal causes panel startup failure 2683 1.1 mrg https://bugs.freedesktop.org/show_bug.cgi?id=17292 2684 1.1 mrg 2685 1.1 mrg [xrandr TV] need TV output property control 2686 1.1 mrg https://bugs.freedesktop.org/show_bug.cgi?id=12763 2687 1.1 mrg 2688 1.1 mrg [TV] "xrandr --set TV_FORMAT" gets BadMatch error 2689 1.1 mrg https://bugs.freedesktop.org/show_bug.cgi?id=16566 2690 1.1 mrg 2691 1.1 mrg [945 tiling] Low performance due to no A17 workaround 2692 1.1 mrg https://bugs.freedesktop.org/show_bug.cgi?id=16835 2693 1.1 mrg 2694 1.1 mrg [TV]Flicker when launching applications in the 2.4-branch 2695 1.1 mrg https://bugs.freedesktop.org/show_bug.cgi?id=17405 2696 1.1 mrg 2697 1.1 mrg [945GM FBC] FBC causes underruns & flicker 2698 1.1 mrg https://bugs.freedesktop.org/show_bug.cgi?id=18651 2699 1.1 mrg 2700 1.1 mrg [xv] Textured video suffers from tearing 2701 1.1 mrg https://bugs.freedesktop.org/show_bug.cgi?id=19635 2702 1.1 mrg 2703 1.1 mrg [G45] Random hangs with UXA 2704 1.1 mrg https://bugs.freedesktop.org/show_bug.cgi?id=19734 2705 1.1 mrg 2706 1.1 mrg [945GM] Any 3D app is slow in resolution higher than 800x600 2707 1.1 mrg with UXA+DRI2, due to tiling 2708 1.1 mrg https://bugs.freedesktop.org/show_bug.cgi?id=19738 2709 1.1 mrg 2710 1.1 mrg [i915 UXA,EXA] rotation messes display with tiling on 2711 1.1 mrg https://bugs.freedesktop.org/show_bug.cgi?id=20265 2712 1.1 mrg 2713 1.1 mrg [G45] DRI2/UXA gives solid white instead of transparency 2714 1.1 mrg https://bugs.freedesktop.org/show_bug.cgi?id=20321 2715 1.1 mrg 2716 1.1 mrg LVDS output not detected 2717 1.1 mrg https://bugs.freedesktop.org/show_bug.cgi?id=20517 2718 1.1 mrg 2719 1.1 mrg xf86-video-intel-2.6.3: Xv crashes X server 2720 1.1 mrg https://bugs.freedesktop.org/show_bug.cgi?id=20525 2721 1.1 mrg 2722 1.1 mrg [G965 non-GEM] systray in KDE 4 completely broken 2723 1.1 mrg https://bugs.freedesktop.org/show_bug.cgi?id=20527 2724 1.1 mrg 2725 1.1 mrg [SDVO-TV]the desktop is teared in four sections on the screen 2726 1.1 mrg https://bugs.freedesktop.org/show_bug.cgi?id=20550 2727 1.1 mrg 2728 1.1 mrg Intel video driver 2.6.3 crashes with XVideo 2729 1.1 mrg https://bugs.freedesktop.org/show_bug.cgi?id=20563 2730 1.1 mrg 2731 1.1 mrg [855GM] Xv crash with non-KMS 2732 1.1 mrg https://bugs.freedesktop.org/show_bug.cgi?id=20585 2733 1.1 mrg 2734 1.1 mrg 2.6.99.902 breaks native 1680x1050 mode on TMDS -- EDID miss 2735 1.1 mrg https://bugs.freedesktop.org/show_bug.cgi?id=20594 2736 1.1 mrg 2737 1.1 mrg [945GM TV] 2.6.99.902 sets a too high CONTRAST-value 2738 1.1 mrg https://bugs.freedesktop.org/show_bug.cgi?id=20670 2739 1.1 mrg 2740 1.1 mrg [915GM] fail to detect LVDS with new VBT code 2741 1.1 mrg https://bugs.freedesktop.org/show_bug.cgi?id=20752 2742 1.1 mrg 2743 1.1 mrg [regression i965]tiled output when start X 2744 1.1 mrg https://bugs.freedesktop.org/show_bug.cgi?id=20803 2745 1.1 mrg 2746 1.1 mrg 2.6.99.902: LVDS wrongly detected as disconnected 2747 1.1 mrg https://bugs.freedesktop.org/show_bug.cgi?id=20826 2748 1.1 mrg 2749 1.1 mrg vt switching fails and crashes X 2750 1.1 mrg https://bugs.freedesktop.org/show_bug.cgi?id=20863 2751 1.1 mrg 2752 1.1 mrg [HDMI] The screen will flicker when some application runs on 2753 1.1 mrg G45-64 2754 1.1 mrg https://bugs.freedesktop.org/show_bug.cgi?id=20875 2755 1.1 mrg 2756 1.1 mrg TexturedVideo is offsetted wrongly on dualhead 2757 1.1 mrg https://bugs.freedesktop.org/show_bug.cgi?id=20980 2758 1.1 mrg 2759 1.1 mrg [EXA] xvideo hang X 2760 1.1 mrg https://bugs.freedesktop.org/show_bug.cgi?id=21027 2761 1.1 mrg 2762 1.1 mrg [EXA] x11perf performance regression 2763 1.1 mrg https://bugs.freedesktop.org/show_bug.cgi?id=21029 2764 1.1 mrg 2765 1.1 mrg And many others... 2766
