1 Snapshot 2.99.917 (2014-12-21) 2 ============================== 3 3 months drifted by whilst I looked elsewhere for bugs.. The highlight of 4 bugs fixed here are a couple of workarounds required for Broadwell and 5 making sure that the rasterisation code is symmetric under inversions. 6 However, as a couple of crashers slipped through into 2.99.916 (though 7 not actual regressions in 2.99.916 per se) and 3 months have passed, we 8 should make one more snapshot before an imminent release. 9 10 * Beware of recomputing the clear hint in the middle of MI recursion 11 https://bugs.freedesktop.org/show_bug.cgi?id=77074 12 13 * Fix crash from rendering an empty Glyph string under PRIME as the 14 secondary driver 15 16 * Restore application of default monitor options to the first output, 17 a regression in 2.99.915 and the MST support 18 https://bugs.gentoo.org/show_bug.cgi?id=522500 19 20 * Finally fix ZaphodHeads blocking on waiting for flip completion events. 21 Before kernel 3.19, O_NONBLOCK support is broken and so we must avoid 22 reading if we are not expecting an event. 23 24 * Backwards compatibilty fix for fake triple buffering with PRIME and 25 Xorg-1.15 26 https://bugs.freedesktop.org/show_bug.cgi?id=85144#c12 27 28 * Fix a rendering issue with output rotation and software fallbacks. 29 https://bugs.freedesktop.org/show_bug.cgi?id=84653 30 31 * Enable MST discovery even without udev support 32 https://bugs.freedesktop.org/show_bug.cgi?id=84718 33 34 * Fix TearFree operation after the GPU is wedged 35 https://bugs.freedesktop.org/show_bug.cgi?id=85058 36 37 * Fix projective sampling on gen6+. 38 39 * Fix rendering and corruption with gen8. 40 https://bugs.freedesktop.org/show_bug.cgi?id=84958 41 https://bugs.freedesktop.org/show_bug.cgi?id=83207 42 https://bugs.freedesktop.org/show_bug.cgi?id=79053 43 https://bugs.freedesktop.org/show_bug.cgi?id=81583 44 45 * Fix crash when using Xinerama. 46 https://bugs.freedesktop.org/show_bug.cgi?id=87207 47 48 * Fix rendering of right-to-left or bottom-to-top PolySegments in UXA 49 50 51 Snapshot 2.99.916 (2014-09-08) 52 ============================== 53 Quick update for MST in UXA - we need to hook up the RandR outputs for 54 dynamicaly added connectors. 55 56 57 Snapshot 2.99.915 (2014-09-08) 58 ============================== 59 A significant change to UXA to enable MST and to keep it working on recent 60 kernels needs some soaking before a major release, and the usual 61 plethora of bugfixes. One other feature is the support for hardware 62 rotations on very recent kernels. 63 64 * Handle rotated scanouts that are all clear correctly. The region to 65 update was not being computed correctly, overdrawing the wrong CRTC. 66 https://bugs.freedesktop.org/show_bug.cgi?id=81820 67 68 * Reset cursor images after rotation and size changes 69 https://bugs.freedesktop.org/show_bug.cgi?id=81886 70 https://bugs.freedesktop.org/show_bug.cgi?id=82273 71 https://bugs.freedesktop.org/show_bug.cgi?id=82337 72 73 * Handle stale DRI2 buffers and Client errors more gracefully 74 75 * Fallback if we fail to render a glyph onto a too-large surface, e.g. 76 direct rendering of glyphs onto extended desktops with gen2/gen3. 77 https://bugs.archlinux.org/task/40949 78 79 * Further work to enable tiled rendering onto large surfaces in 80 severely aperture and memory constrained devices (e.g. gen2/gen3) 81 82 * Honour the Primary option from xorg.conf and mark that as the RandR 83 primary. 84 https://bugs.freedesktop.org/show_bug.cgi?id=82193 85 https://bugs.freedesktop.org/show_bug.cgi?id=82205 86 87 * Fix another Client-Window DRI2 close race 88 https://bugs.freedesktop.org/show_bug.cgi?id=82979 89 90 * Fix incorrect discarding of GPU damage when copying over the TearFree 91 scanout - which caused a flicker in rapidly updated elements (like 92 simple video panes). 93 https://bugs.freedesktop.org/show_bug.cgi?id=81973 94 95 96 Snapshot 2.99.914 (2014-07-23) 97 ============================== 98 And a brown paper bag to hide the rebuilding from the tarball with 99 'autoreconf -fi' error that arose from not distributing the libobj/ 100 directory. 101 102 103 Snapshot 2.99.913 (2014-07-23) 104 ============================== 105 This should be it... A few fixes from testing the new code, we should be 106 ready for the final release. However, we do have one standout feature in 107 this snapshot, we now officially recognise HD Graphics 5300/5500/5600, 108 Iris Graphics 6100 and Iris Pro Graphics 6200/P6300 (formerly known as 109 Broadwell). 110 111 * Check the window actually covers the CRTC before doing a single CRTC flip, 112 and then restore the right framebuffer after completing CRTC flips. 113 Otherwise we would detect an error and disable an output under TearFree 114 Regression in 2.99.912 115 https://bugs.freedesktop.org/show_bug.cgi?id=80191 116 117 * Fix framebuffer creation on kernels older than 3.11 118 Regression in 2.99.912 119 120 * Check that the damage still exists after implicit reduction 121 Regression in 2.99.912 122 https://bugs.freedesktop.org/show_bug.cgi?id=77436 123 124 * Fix direction flags for fallback composited CopyAreas which 125 caused scrolling corruption in a few configurations 126 Regression from 2.20.0 127 https://bugs.freedesktop.org/show_bug.cgi?id=79843 128 129 * Do not throw away damage if there is no redundant copy 130 https://bugs.freedesktop.org/show_bug.cgi?id=79992 131 132 * Check clipping on PolyRect before discarding the clipped damage 133 Regression from 2.99.903 134 https://bugs.freedesktop.org/show_bug.cgi?id=79992 135 136 * Fix hints for GLXPixmapa, as these are never swapped and so 137 miss invalidating the hints on SwapBuffers with the result 138 that they are often presumed blank 139 Regression in 2.99.912 140 https://bugs.freedesktop.org/show_bug.cgi?id=79999 141 142 * Fix incoherent choice of source bo when constructing 8x8 tiles, 143 incorrect pattern origin when extracting, and then fix the 144 alignment of colour patterns for BLT operations 145 https://bugs.freedesktop.org/show_bug.cgi?id=80033 146 147 * Disable blending with the render engine on snoopable buffers 148 https://bugs.freedesktop.org/show_bug.cgi?id=80253 149 150 * Restore throttling to prevent client lag under heavy GPU load 151 Regression from 2.21.10 152 https://bugs.freedesktop.org/show_bug.cgi?id=77436 153 154 * Use ClientGone for notifications on shared DRI2 windows to prevent 155 rare crashes due to use-after-free of the swap requests 156 https://bugs.freedesktop.org/show_bug.cgi?id=80157 157 158 * Ensure the mmaped CPU bo is idle before migrating damage 159 https://bugs.freedesktop.org/show_bug.cgi?id=80560 160 161 * Fix incorrect clipping by the render engine for large DRI2 windows 162 163 * Ensure that the aperture tiling fallbacks are bounded 164 165 * Validate parameter to xf86-video-intel-backlight-helper more carefully 166 (CVE-2014-4910) 167 168 * Fix slaved scanouts for reverse optimus, though rotated slaves will 169 require further patches to Xorg. 170 https://bugs.freedesktop.org/show_bug.cgi?id=81383 171 172 * Fix build without Composite extension. 173 174 * Fix build without gettline(). 175 176 * UXA: Allocate and resize frontbuffer consistently to pass sanity checks 177 https://bugs.freedesktop.org/show_bug.cgi?id=80088 178 179 * UXA: Report cached backlight value when the output is off (like sna) 180 https://bugzilla.redhat.com/show_bug.cgi?id=1032978 181 182 * UXA: Mark outputs as off before the kernel does (like sna) 183 This will prevent the internal panel from starting up blank in some 184 multi-monitor configurations 185 https://bugzilla.redhat.com/show_bug.cgi?id=1103806 186 187 Note that the DRI2 exchange mechanism introduced in 2.99.912 exposes bugs 188 in some compositors, at least kwin and comptom, which discard DRI2 buffer 189 invalidates rather than resourcing their texture. For example, 190 https://bugs.kde.org/show_bug.cgi?id=336589 191 192 Note that the improved triple buffering introduced in DRI2 requires a patch 193 to Xorg (now released upstream) to prevent crashes with DRI_PRIME. 194 https://bugs.freedesktop.org/show_bug.cgi?id=80001 195 196 Note that DRI3/Present require tracking the relevant development trees for 197 mesa and the xserver as they are very much still under early testing. Also 198 be aware that Mesa provides no support for explicit fencing so Damage 199 tracking between compositors and clients is unserialised. 200 201 202 Snapshot 2.99.912 (2014-06-10) 203 ============================== 204 A final round of features. We have everything from support for variable 205 cursor sizes, support for the DRI3 and Present extensions, improved DRI2 206 support, support for Xserver 1.16, userptr from kernel 3.16, and 207 precursory support for DP multistream transport, 208 209 * Avoid discarding dirty pixels when promoting a migration to cover the 210 whole pixmap. 211 Regression in 2.99.911 212 https://bugs.freedesktop.org/show_bug.cgi?id=77063 213 https://bugs.freedesktop.org/show_bug.cgi?id=77178 214 215 * Avoid overextending degenerate lines (and consequentially accessing 216 pixels outside of our damaged area). 217 https://bugs.freedesktop.org/show_bug.cgi?id=77074 218 219 * Fix subpixel glyph rendering on gen2 devices (830-865 chipsets) 220 Regression in 2.99.911 221 https://bugs.freedesktop.org/show_bug.cgi?id=77201 222 223 * Share the global pixman glyph cache between ZaphodHeads 224 https://bugs.freedesktop.org/show_bug.cgi?id=54707 225 226 * Light up all connected outputs, even if their status is unknown, on 227 takeover from fbcon. This prevents loss of display after a resume 228 on recent kernels, for example. 229 https://bugs.freedesktop.org/show_bug.cgi?id=77768 230 231 * Show the video overlay (when supported by the hardware) across all 232 outputs. 233 https://bugs.freedesktop.org/show_bug.cgi?id=77802 234 235 * Do not discard damage when performing "BLT" spans inplace with the CPU. 236 Regression from 2.20.10 237 238 * Avoid discarding IO buffers too early during their preparation for a 239 new batch 240 https://bugs.freedesktop.org/show_bug.cgi?id=79238 241 242 * Fix fallback handling for displaying large scaled framebuffers (that 243 are too large to be scaled by the GPU in a single pass) 244 https://bugs.freedesktop.org/show_bug.cgi?id=79320 245 246 * Listen to external modifications of backlight value and propagate 247 the notifications to RandR clients. This should make the GUI report 248 ACPI keypresses to change the backlight correctly. 249 https://bugs.freedesktop.org/show_bug.cgi?id=79699 250 251 * UXA: fix pageflips with 3 heads. 252 253 * UXA: do not report a BadMatch error for DRI2GetMsc - as clients are 254 often unprepared and die when they get the unexpected error. 255 256 257 Snapshot 2.99.911 (2014-03-19) 258 ============================== 259 Hans de Geode has been working on making the Xserver work without 260 privileges under the supervision of systemd/logind. This necessitated a 261 few new features for us: server fds (where we are passed which fd to use 262 to talk to our device by the Xserver who may in turn receive it from 263 logind or other host) and a small backlight helper so that we can continue 264 to provide a RandR backlight property when running without root privileges. 265 266 * Flush when changing blend modes on Ironlake, or else single glyphs 267 are sometimes rendered incorrectly 268 Regression from 2.20.15 269 https://bugs.freedesktop.org/show_bug.cgi?id=74882 270 271 * Fix pixmap offsets for pixman fallbacks onto Composite redirected 272 windows 273 https://bugs.freedesktop.org/show_bug.cgi?id=73811 274 275 * Fix blending onto 8-bit destinations, typically used for generating 276 masks in complex Render operations, on gen2 277 https://bugs.freedesktop.org/show_bug.cgi?id=75818 278 279 * Handle failure to create DRI bo more carefully. For example on gen3, 280 the DDX supports pixmaps that are much, much larger than OpenGL can 281 use and do not support the tiling modes that we request for OpenGL. 282 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1289049 283 284 * Fix a bookkeeping bug with proxy buffers that are marked active but 285 not actually inserted into a request (so they end up permanently 286 active and confuse everybody). 287 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1289923 288 289 * Actually turn off displays with DPMS off for UXA. 290 Regression from 2.99.903, but requires 291 292 kernel commit c9976dcf55c8aaa7037427b239f15e5acfc01a3a 293 Author: Chris Wilson <chris (a] chris-wilson.co.uk> 294 Date: Sun Sep 29 19:15:07 2013 +0100 295 296 drm/i915: Only apply DPMS to the encoder if enabled 297 298 instead for correct behaviour on Haswell. 299 https://code.google.com/p/chromium/issues/detail?id=341135 300 301 302 Snapshot 2.99.910 (2014-02-10) 303 ============================== 304 Another latent bug exposed by recent changes merit another snapshot for 305 final testing. 306 307 * Only discard damage when overwriting the dirty CPU bo, instead 308 of discarding damage that will be shown! 309 310 * Reset operation state when switching between glyph caches. 311 https://bugs.freedesktop.org/show_bug.cgi?id=74494 312 313 * Fully reinitialise pixmaps allocated from the freed cache. Fixes 314 a potential issue (crash or misrendering) when using some compositors. 315 https://bugs.freedesktop.org/show_bug.cgi?id=74550 316 317 * Do not expose the TexturedVideo adaptor in UXA when it is disabled 318 either due to a hung GPU or explicitly disabled by the user. 319 320 * Restore the pipe stall when changing CC state on gen6, otherwise 321 the GPU may not flush intermediate results from all EU resulting 322 in render corruption (usually the occasional black box). 323 Regression from 2.99.906 324 https://bugs.freedesktop.org/show_bug.cgi?id=7237 325 326 327 Snapshot 2.99.909 (2014-02-01) 328 ============================== 329 Pass the brown paper bag. Ridiculously stupid bug in last minute coding. 330 331 * Add Xv support using glamor acceleration in addition to adaptors 332 provided by the UXA backend. 333 334 * Fix overeager discarding of CPU damage 335 Regression in 2.99.908 :( 336 https://bugs.freedesktop.org/show_bug.cgi?id=74327 337 338 339 Snapshot 2.99.908 (2014-01-31) 340 ============================== 341 A couple of regressions dashed the hopes that .907 was to be the final 342 release candidate, so time to start the cycle again after applying a few 343 more bugfixes. 344 345 * Fix invalid pageflipping of GLXPixmaps by UXA. 346 https://bugs.freedesktop.org/show_bug.cgi?id=73282 347 348 * Consistently treat DPMS Suspend/Standy as Off, otherwise we may 349 incorrectly restore the backlight in UXA. 350 351 * Fix disabling the backlight in UXA when querying the value whilst off 352 https://bugs.freedesktop.org/show_bug.cgi?id=73181. 353 354 * Invalidate between every operation if rendering into the source or mask. 355 Fixes regression in 2.99.907 on Ivybridge (seen in KDE) 356 https://bugs.freedesktop.org/show_bug.cgi?id=73208 357 358 * Check for available batch buffer state before restoring state on gen4, 359 otherwise we overwrite surface state with commands and cause a GPU hang. 360 https://bugs.freedesktop.org/show_bug.cgi?id=73348 361 362 * Prevent an invalid free by TearFree 363 https://bugs.freedesktop.org/show_bug.cgi?id=73469 364 365 * Fix confusion in TearFree when it tried to pageflip to a stale bo 366 https://bugs.freedesktop.org/show_bug.cgi?id=70905 367 368 * Initialise TearFree contents with the current frontbuffer upon creation, 369 otherwise old content may be visible for significant fractions of a 370 second after resume or DPMS on 371 https://bugs.freedesktop.org/show_bug.cgi?id=73842 372 373 * Nullify the old pointer into a CPU mmapping of the bo when promoting it 374 on the GPU. Eventually that old pointer becomes invalid and will cause 375 the Xserver to crash. 376 Fixes regression in 2.99.906 377 https://bugs.freedesktop.org/show_bug.cgi?id=73351 378 379 * Restore the serialNumber on the GC correctly after falling back to 380 software. This was seen to cause corruption with Wine. 381 https://bugs.freedesktop.org/show_bug.cgi?id=73856 382 383 * Do not ignore CPU damage on a pixmap unless the Composite operation 384 will completely overwrite it. This was observed in xfce4. 385 https://bugs.freedesktop.org/show_bug.cgi?id=69528 386 387 * Skip fake outputs during initial probe as they can cause a NULL pointer 388 dereference. 389 https://bugs.freedesktop.org/show_bug.cgi?id=73981 390 391 * Fix rendering of dashed zero-width lines onto 24bit buffers 392 https://bugzilla.redhat.com/show_bug.cgi?id=1059152 393 394 * Cap the freed Pixmap cache and reuse it more often 395 Fixes a regression in 2.99.907 that caused the memory used by X to 396 grow until it was cleaned up during server regreneration 397 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1272338 398 399 400 Snapshot 2.99.907 (2013-12-30) 401 ============================== 402 The highlight here is that things seem to be quietening down on the bug 403 reporting front. All is not quiet as you will see below, and maybe it is 404 just the holiday season that is approaching*, but there has been a 405 remarkable falloff in bug reports. Lets hope this trend holds and we can 406 make a stable release shortly! 407 408 * This was intended to be sent a couple of weeks ago and the holiday season 409 has been very quiet.... 410 411 Oh, and acceleration support for Intel's next generation of 412 integrated processor graphics has landed, codenamed Broadwell. 413 414 * Fix potential X server infinite recursion (crash) from a gen2 bug fix 415 Regression in 2.99.906 416 https://bugs.freedesktop.org/show_bug.cgi?id=71605 417 418 * Workaround a missing pipeline flush within Ivybridge, that would 419 leave black rectangles randomly over the output 420 https://bugs.freedesktop.org/show_bug.cgi?id=68410 421 422 * Fix tiled fills. gen2-3 and gen4+ had two different bugs that 423 both broke rendering with small 8x8 patterns in some circumstances 424 https://bugs.freedesktop.org/show_bug.cgi?id=71260 425 426 * Fix reads from a cropped video image using a packed pixel format. 427 428 * Another clear the clear hint after DRI2 SwapBuffers, like the bug fixed 429 in 2.99.903. Failure to clear the hint would cause read backs of the 430 frontbuffer (Xvnc) to be blank. 431 https://bugs.freedesktop.org/show_bug.cgi?id=72194 432 433 * Disable VSync on Baytrail 434 https://bugs.freedesktop.org/show_bug.cgi?id=69869 435 436 * Handle partial uploads with TearFree correctly 437 https://bugs.freedesktop.org/show_bug.cgi?id=72343 438 https://bugs.freedesktop.org/show_bug.cgi?id=72430 439 440 * Avoid recusing through DRI event handlers whilst processing TearFree, 441 leading to a double free (and memory corruption) 442 https://bugs.freedesktop.org/show_bug.cgi?id=72690 443 444 * Hide the gen4 render corruption by crippling the GPU 445 https://bugs.freedesktop.org/show_bug.cgi?id=55500 446 447 448 Snapshot 2.99.906 (2013-11-13) 449 ============================== 450 Several stability fixes required after the recent tweaking of the core 451 mechanics to handle the updated TearFree and attempting to make static 452 analyzers happy. 453 454 * Fix damage handling when rendering to a partially damaged GPU surface. 455 Regression in 2.99.905 456 https://bugs.freedesktop.org/show_bug.cgi?id=70527 457 458 * Use asprintf() instead of sprintf() 459 Regression in 2.99.905 460 https://bugs.freedesktop.org/show_bug.cgi?id=70835 461 462 * Improve accounting for fence overallocation on older gen2/3, and 463 improve the tiling mechanism to fit into the same aperture constraints 464 https://bugs.freedesktop.org/show_bug.cgi?id=70924 465 466 * Add an extra GPU flush on Sandybridge to fix some rare font corruption 467 468 * Rasterise lines through all clip boxes 469 https://bugs.freedesktop.org/show_bug.cgi?id=70802 470 471 * Fix regression from stricter handling of failures to move a GC to the GPU 472 Regression in 2.99.905 473 https://bugs.freedesktop.org/show_bug.cgi?id=71415 474 475 * Fix various fail along the memcpy_xor paths, including inadequate error 476 handling and integer overflow 477 https://bugs.freedesktop.org/show_bug.cgi?id=70527 478 479 * Fix outside-of-target stipple uploads 480 https://bugs.launchpad.net/bugs/1247785 481 482 * Fix clip detection for long glyphs 483 Incomplete bug fix (causing a regression) in 2.99.905 484 https://bugs.freedesktop.org/show_bug.cgi?id=70527 485 486 * Fix VSync for the render engine (Xv) on Haswell 487 https://bugs.freedesktop.org/show_bug.cgi?id=70527 488 489 490 Snapshot 2.99.905 (2013-10-23) 491 ============================== 492 The highlight for this snapshot is the extension of TearFree to support 493 transformed outputs, along with some polishing to eliminate its impact 494 upon input and output latency. As always, thanks to everyone who have 495 been testing, reporting bugs and helping to improve the stability before 496 release. 497 498 * Prevent a crash when starting with a user specified mode or position 499 500 * Prevent some crashes in UXA after allocation failure 501 502 * Stop marking the user's preferred backlight value as 0 if the 503 backlight property is queried whilst the connector is disabled 504 https://bugs.freedesktop.org/show_bug.cgi?id=70406 505 506 * Pad GETCONNECTOR ioctl for compatability between 32/64-bit userspace 507 and kernel 508 509 * Handle long glyph runs correctly 510 https://bugs.freedesktop.org/show_bug.cgi?id=70541 511 512 * Fix clipping of stippled rectangles against clip regions 513 https://bugs.freedesktop.org/show_bug.cgi?id=67865 514 515 * Support TearFree rendering of rotated outputs 516 https://bugs.freedesktop.org/show_bug.cgi?id=22969 517 518 519 Snapshot 2.99.904 (2013-10-09) 520 ============================== 521 There is one more feature planned to be completed for 3.0, so time for a 522 snapshot beforehand to push out the bug fixes from the last week. 523 524 * Fix video output using sprites when changing the image size 525 526 * Apply more restrictive tile constaints for 915g class devices 527 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1232546 528 529 * Ensure all overlapping rectangles are drawn for XRenderFillRectangles 530 https://bugs.freedesktop.org/show_bug.cgi?id=66313 531 532 * Fix trapezoid clipping against the left-edge 533 https://bugs.freedesktop.org/show_bug.cgi?id=69469 534 535 * Prevent discarding active upload buffers, causing glitches in chromium 536 https://bugs.freedesktop.org/show_bug.cgi?id=66990 537 538 * Prevent specifying a negative timeout to select if the BlockHandler 539 takes too long to update the display 540 541 * Promote the Ironlake pipecontrol to be a full pipeline flush to 542 prevent render cache corruption 543 https://bugs.freedesktop.org/show_bug.cgi?id=51422 544 545 * Never pass an invalid trapezoid to pixman 546 https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1197921 547 548 * Prevent out-of-bounds access by overassigning work amongst threads 549 https://bugs.freedesktop.org/show_bug.cgi?id=70204 550 551 * Make sure the current mode is always listed amongst the output modes 552 https://bugs.freedesktop.org/show_bug.cgi?id=70132 553 554 * Build fixes for 1.14.99.2 555 556 557 Snapshot 2.99.903 (2013-09-28) 558 ============================== 559 Lots more stabilization work, not yet peaceful enough to christen 3.0. We 560 have everything ranging from build fixes for systems like Suse Linux 561 Enterprise Desktop that like to backport hardware enablement to ancient 562 packages, to fixes for hardware enabling, and some more performance tuning. 563 564 * Fix VSync on Haswell. 565 https://bugs.freedesktop.org/show_bug.cgi?id=69119 566 567 * Disable Y-tiling on gen4 - it too frequently leads to instability. 568 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1222203 569 570 * Disable same EDID detection based on property id - the kernel likes 571 to reuse ids leading to a failure to detect the right modes on a monitor 572 change. 573 574 * Avoid issuing multiple DPMS requests to the same encoder (alised to 575 multiple connectors) to avoid upsetting Haswell and leaving the 576 screens blank. 577 578 * Honour the user preferrence for the initial mode, even if they are 579 being silly 580 https://bugzilla.novell.com/show_bug.cgi?id=841696 581 582 * Clear the clear hint when apply DRI updates - to prevent some 583 screenshots from GL windows being left blank. 584 https://bugs.freedesktop.org/show_bug.cgi?id=69730 585 586 * Prevent a NULL dereference from trying to undo an non-existent buffer 587 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1228677 588 589 * Handle out-of-memory conditions far more gracefully. If the system is 590 hard against the memory wall, then the kernel will start issuing 591 SIGBUS even for CPU mmaps. Untrapped these will cause X to die. 592 https://bugs.freedesktop.org/show_bug.cgi?id=67889 593 594 595 Snapshot 2.99.902 (2013-09-07) 596 ============================== 597 We do not condone or support Canonical in the course of action they have 598 chosen, and will not carry XMir patches upstream. 599 -The Management 600 601 Snapshot 2.99.901 (2013-09-04) 602 ============================== 603 What's this? A pre-release snapshot of an upcoming 3.0 major release? 604 What could be the big new feature about to land? SNA by default! 605 Not only that, we also have a preview of the XMir integration patches. 606 607 Whilst we consider the SNA acceleration method to be ready to take over 608 from UXA (the current acceleration method), it still remains possible to 609 switch over to the old method with the following xorg.conf snippet: 610 Section "Device" 611 Identifier "Device0" 612 Driver "intel" 613 Option "AccelMethod" "UXA" 614 EndSection 615 616 The promise of SNA is that it improves the user experience by providing a 617 faster, more fluid, desktop, that is both more power efficient and less 618 prone to crashes than UXA. If it still fails to meet your expections, 619 please file bugs! 620 621 622 Release 2.21.15 (2013-08-21) 623 ============================ 624 Some build fixes for the BSDs and alternate compiler, and conflicting 625 configure options and a critcial fix for some PRIME setups. 626 627 * Don't fail to configure if DRI1 is not available and the user asks 628 for both DRI and KMS-only 629 [Regression from 2.21.14] 630 631 * Lots of miscellaneous fixes for older gcc, other compilers and BSD. 632 633 * Initial framework support for hosted X. 634 635 * Improve transition from fbcon to X with multiple outputs and extended 636 desktops. 637 638 * Ensure the framebuffer exists before checking it against the CRTC 639 constraints. 640 https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/121234 641 [Regression from 2.21.10] 642 643 * Add RGB overlay support for Ironlake and later. 644 645 * Don't release the overlay buffer too early, i.e. before the client 646 disables the Xv image. 647 648 * Tweak the ring switching logic to reduce use of semaphores on 649 Sandybridge and later - a delicate balancing act between trying to 650 use the faster engine for the task and preventing concurrent use of 651 multiple rings. 652 653 654 Release 2.21.14 (2013-08-04) 655 ============================ 656 A few updates for the top-end Haswell systems (notably GT3 and GT3e 657 systems), in particular, setting the appropriate thread counts for the 658 larger GPU and handling a few scaling issues with the emedded DRAM. More 659 important than the performance tuning though is a fix for a critical 660 issue encountered by a few people on gen4/gen5 systems. 661 662 * Initial performance tuning for HSW:GT3e 663 664 * Fix a crash with Planetary Annihilation 665 666 * Disable triple buffering for compositors 667 668 * Reserve space in the exec buffer array for deferred VBOs. 669 https://bugs.freedesktop.org/show_bug.cgi?id=67504 670 671 672 Release 2.21.13 (2013-07-27) 673 ============================ 674 A minor release to repair the build for non-Linux systems, and to undo a 675 few more regressions. 676 677 * Avoid potential memory corruption with allocations of very small 678 depth 1 bitmaps. 679 680 * Fix source clipping whilst computing copy extents and exposures. 681 [Regression from 2.21.12] 682 https://bugs.freedesktop.org/show_bug.cgi?id=66970 683 684 * Use /proc/cpuinfo if cpuid4 is not available (old hardware or old 685 gcc), and repair the build on systems without cpuid. 686 [Regression from 2.21.12] 687 688 * Fix performance regression on Ironlake from inadvertently flushing 689 after every operation. 690 [Regression from 2.21.11] 691 https://bugs.freedesktop.org/show_bug.cgi?id=67157 692 693 * Fix conflict handling when probing initial KMS configuration for 694 ZaphodHeads. 695 [Regression from 2.21.11] 696 https://bugs.freedesktop.org/show_bug.cgi?id=67176 697 698 * Stop being overly restrictive and rejecting stale DRI2 buffers. 699 (DRI2 is inherently racy in that the client may have completed and 700 submitted rendering to buffers that are now invalid on the server. 701 This race is magnified by bugs within the Xserver where it forgets 702 to notify the DRI2 clients of certain invalidation events.) 703 https://bugs.freedesktop.org/show_bug.cgi?id=67210 704 705 * Handle a failure to use a GTT mmap for a pixmap upload and try 706 an alternative method before giving up. 707 708 709 Release 2.21.12 (2013-07-14) 710 ============================ 711 In this release, we clear up the teething troubles from preserving the KMS 712 configuration, notably external connections on Haswell and plugging in new 713 outputs after startup were broken. Besides these regression fixes, there 714 are a couple of fixes for some long standing issues, such as incorrect 715 rendering on gen2, an infinite loop with very, very large pixmaps and a 716 slight improvement to the tempermental gen4. 717 718 * Allow untiled scanouts again (required for large extended desktops on 719 gen2 and gen3). 720 [Regression from 2.21.11] 721 722 * Use the correct count of the number of dirty damage boxes for the quick 723 check on whether the existing damage contains the requested area. 724 The danger is that we may get a false result and skip migration and so 725 cause pixmap corruption (in the unlikely event that the application 726 frequently causes fallbacks). 727 [Regression from 2.21.11] 728 https://bugs.freedesktop.org/show_bug.cgi?id=66430 729 730 * Fix initial connection probing for multi-function encoders, such as the 731 external connections on Haswell. 732 [Regression from 2.21.11, initial connection probing] 733 https://bugs.freedesktop.org/show_bug.cgi?id=66488 734 735 * Fix gen2 rendercopy into a8 surfaces, for example, glyph uploads into 736 the glyph cache. 737 738 * Fix detection of user overrides for initial connection configuration. 739 The code used the xorg-server-1.15 values, having missed the 740 introduction of ZoomModes into that release. 741 [Regression from 2.21.11, initial connection probing] 742 743 * Always initialise the gamma ramp, even on unconnected CRTCs. 744 https://bugs.freedesktop.org/show_bug.cgi?id=66563 745 [Regression from 2.21.11, initial connection probing] 746 747 * Some more tuning of the gen4 vertex corruption workaround. The root 748 cause behind the GPU using incorrect texture coordinates is still 749 not solved, but by reducing the maximum number or rectangles in 750 flight through the GPU we reduce the likelihood of corruption. 751 752 * Fix compilation with gcc-4.5 753 [Regression from 2.21.11] 754 755 * Avoid integer overflow when performing tiled uploads and operations 756 on very large (>28k pixels wide or tall pixmaps) 757 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1200766 758 759 760 Release 2.21.11 (2013-06-30) 761 ============================ 762 An eventful week. What started with a regression with some builds of 763 firefox on some machines lead ultimately to the discovery of an older 764 kernel bug. Aside from the work to fix the image bug and a few other 765 older bugs that were reported and resolved this week, there is also a 766 (hopefully) subtle change to the initial configuration of displays. In 767 the absence of user overrides in xorg.conf, the DDX will try to preserve 768 the same display configuration as used by the kernel, which hopefully 769 will be the same configuration as setup by the BIOS. The result should 770 be a boot sequence that does not resize at all (aka fastboot) - until 771 the display manager takes over and loads a completely different 772 configuration! 773 774 * Add reference counting of drmMaster for ZaphodHeads 775 https://bugs.freedesktop.org/show_bug.cgi?id=66041 776 777 * Add a GPU flush before changing blend modes on Ironlake 778 https://bugs.freedesktop.org/show_bug.cgi?id=51422 779 780 * Fix occasional missing images for inplace uploads 781 [regression from 2.21.10] 782 https://bugs.freedesktop.org/show_bug.cgi?id=66059 783 784 * Add missing utility files to the tarball and remove a few unused ones 785 786 * Initialise PolyPoint operand state before calling miWideDash 787 https://bugs.freedesktop.org/show_bug.cgi?id=66104 788 789 * Fix redirection handling for rendering into large surfaces 790 https://bugs.freedesktop.org/show_bug.cgi?id=66168 791 https://bugs.freedesktop.org/show_bug.cgi?id=66249 792 793 * Fix compilation of UXA with xorg-xserver < 1.10 794 [regression from 2.20.0] 795 796 * Fix consideration of gradients for deciding when to migrate render 797 operations 798 [performance regression from 2.21.10, the bug itself is older] 799 https://bugs.freedesktop.org/show_bug.cgi?id=66297 800 801 Also fixed this week was: 802 803 commit 22fd5ca947b58901927d100d2b1aa0f1672b3435 804 Author: Chris Wilson <chris (a] chris-wilson.co.uk> 805 Date: Fri Jun 28 16:54:08 2013 +0100 806 807 drm/i915: Only clear write-domains after a successful wait-seqno 808 809 which affects kernels 3.7 - 3.10, coming to a stable kernel near you soon. 810 811 812 Release 2.21.10 (2013-06-22) 813 ============================ 814 Fixes missing support for Xv (with the textured video adaptor) on 815 Haswell, and an old bug with wide monitors on various generation. Along 816 with a few other regression fixes and performance tweaks for various 817 corner cases. 818 819 * Do not lose track of fast pageflips across mode changes 820 [regression from 2.20.8] 821 822 * Fix listing of Visuals for Xv 823 [regression from 2.21.8] 824 https://bugs.freedesktop.org/show_bug.cgi?id=65479 825 826 * Improve coherency of concurrent CPU accesses to a pixmap 827 https://bugs.freedesktop.org/show_bug.cgi?id=61628 828 829 * Set sampler swizzling for textured video on Haswell 830 https://bugs.freedesktop.org/show_bug.cgi?id=65699 831 832 * Apply scanout stride limits 833 https://bugs.freedesktop.org/show_bug.cgi?id=65099 834 835 * Undo the self-copy for cloned pixmaps for loimpress's animations 836 [regression from 2.21.7] 837 https://bugs.freedesktop.org/show_bug.cgi?id=65665 838 839 840 Release 2.21.9 (2013-06-06) 841 =========================== 842 Consolidating the copy-on-write support, hopefully cleaning up the last of 843 the regressions. 844 845 * Restore vsync on textured videos. 846 [regression from 2.21.8] 847 https://bugs.freedesktop.org/show_bug.cgi?id=65048 848 849 * Fix incorrect ordering of possible_clones with certain outputs, which 850 can lead to attempting to incorrectly clone 2 outputs and failing to 851 light them up. 852 [regression from 2.20.10] 853 854 * Fix performance regression from not promoting large fills to the GPU 855 [regression from 2.21.7] 856 857 * Undo the pixmap clone before performing a DRI2CopyRegion 858 [regression from 2.21.7] 859 https://bugs.freedesktop.org/show_bug.cgi?id=65250 860 861 862 Release 2.21.8 (2013-05-27) 863 =========================== 864 A quick release to cleanup a few regressions from the introduction of 865 copy-on-write support, notably hitting wine applications and a memory 866 leak for firefox. 867 868 * Only mark a PolyFillRect operation as replacing if it is unclipped 869 https://bugs.freedesktop.org/show_bug.cgi?id=64841 870 871 * Prevent potential NULL dereference of damage when checking COW support 872 873 * Fix invalidation of clone after dirtying the pixmap via the CPU 874 875 * Prevent discarding an operation before requiring it for a fallback 876 877 * Fix memory leak from replacing the clone under certain circumstances 878 https://bugs.freedesktop.org/show_bug.cgi?id=64978 879 880 881 Release 2.21.7 (2013-05-21) 882 =========================== 883 A couple of weeks turned into a month and a couple of weeks... Amidst 884 the usual bug fixes, we have added the complete set of Haswell PCI IDs - 885 hopefully future proofing ourselves against being surprised by new 886 products. We can also now use the correct term for the top of the range 887 Haswell variants, GT3. 888 889 * Fix several assertion failures hit by Jiri Slaby. 890 891 * Allow XvMC to also target overlay/sprite planes. 892 893 * Throw in a paranoid MI_FLUSH between BLT and RENDER operations on 894 Ironlake. 895 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1168066 896 897 * Prevent reuse of old framebuffers after a resize. 898 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1157678 899 900 * Fix compilation with --enable-valgrind and no --enable-debug 901 902 * Improve partial migration of render sources. 903 904 * Fix origin of trapezoids. 905 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1178020 906 907 * Introduce copy-on-write support for cloning pixmaps. The ultimate 908 goal here is to efficiently support the TearFree mode of operation, 909 but this provides immediate benefits with firefox - most importantly 910 because of the inefficient way it now implements scrolling. 911 912 913 Release 2.21.6 (2013-04-06) 914 =========================== 915 A surprising highlight of this release is a little refresh to the KMS 916 support for OpenBSD. OpenBSD now has its own KMS implementation which is 917 mostly compatible with the interface in Linux, with one or two tweaks 918 supplied by Mark Kettenis. This release continues to cleanup behaviour 919 for Haswell. 920 921 * Workaround a failure by the xserver to invalidate DRI buffers 922 following a pixmap change for XComposite redirection. 923 https://bugs.freedesktop.org/show_bug.cgi?id=62614 924 925 * Fix computation of clip extents for stippling 926 https://bugs.freedesktop.org/show_bug.cgi?id=62618 927 928 * Support KMS on OpenBSD, by Mark Kettenis 929 930 * Clean up sockets upon CloseScreen (making ourselves better behaved 931 for muxed setups). 932 933 * Fix the tests for AVX/AVX2 support in CPUID and remember to check for 934 OS support as well. 935 936 * Report a monotonic UST value for undisplayed drawables rather than 0 937 by Daniel Kurtz 938 939 * Fix video playback on gen4 through a complex clip (more gen4 GPU woes) 940 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1162046 941 942 943 Release 2.21.5 (2013-03-21) 944 =========================== 945 Haswell reintroduces a command to load the scanline window from the 946 command stream and so requires its own specialised wait-for-vsync routine 947 - failure to do so was then causing hangs when trying to do tearfree video 948 or use a compositor. 949 950 * Prevent buffer leak if a non-fullscreen Window is closed with multiple 951 pending swap events. 952 953 * Fix offset transformation for fallback gradient paths. 954 https://bugs.freedesktop.org/show_bug.cgi?id=62198 955 956 * Prevent Glamor from crashing if misconfigured. 957 Thanks to Michel Dnzer. 958 959 * Prevent UXA from crashing if torn down during PreInit. 960 Thanks to Aaron Plattner. 961 962 * Prevent miscompilation with different functional units having different 963 compiler flags. Some functions were expected to be inlined and so 964 recompiled with the current target. However, some compilers were 965 choosing to emit subroutine calls instead without noticing that the 966 ABI was different between the caller and callee - causing corruption. 967 https://bugs.freedesktop.org/show_bug.cgi?id=62198 968 969 * Fix rendering of CompositeTriFan with recent Xorg. 970 971 * Apply the video src-offset fix highlighted in the last release! 972 A typo prevented the fix from working for gen4+. 973 https://bugs.freedesktop.org/show_bug.cgi?id=62343 974 975 * Fix rendering of multiple glyphs to very large destination surfaces 976 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1156387 977 978 * Fix scanline waits for Haswell 979 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1156679 980 981 982 Release 2.21.4 (2013-03-11) 983 =========================== 984 More bugs, more fixes, more releases. A minor new feature being introduced 985 is the runtime detection of CPU instructions sets along with specialised 986 paths to take advantage of the available CPU. 987 988 * Honour LinearFramebuffer for clumsy PowerXpress integration 989 990 * Disable read-read optimisations of mappings whilst the root 991 cause of a corruption issue remains elusive. 992 https://bugs.freedesktop.org/show_bug.cgi?id=61628 993 994 * Disable 8-bpp framebuffers in UXA as the regressions therein 995 remain unfixed. 996 997 * Restart vertex checks after lock contention 998 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1124576 999 1000 * Handle Screen Pixmap recreation whilst exported via PRIME. 1001 1002 * Correct application of scale factors to video source offsets. 1003 https://bugs.freedesktop.org/show_bug.cgi?id=61610 1004 1005 * Chain up CloseScreen so that resources are actually freed across regen 1006 https://bugs.freedesktop.org/show_bug.cgi?id=56608 1007 1008 * Fix Haswell CRW PCI-IDs 1009 1010 * Handle batch submission failure during DRI copies 1011 https://bugs.freedesktop.org/show_bug.cgi?id=61708 1012 1013 * Probe for kernel support of requested Screen depth 1014 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1135403 1015 1016 * Correct GPU limits for early gen2 and gen3 architectures and prevent 1017 an infinite recursion for particular image sizes. 1018 1019 1020 Release 2.21.3 (2013-02-20) 1021 =========================== 1022 A few minor bugfixes, another point release. 1023 1024 * Fix tracking of DRI pixmaps and their backing bo across reparenting. If 1025 we tried to execute a SwapBuffers after a Window was reparented, but 1026 before the DRI client has updated its references, then we would end up 1027 manipulating an exported pixmap without a flush flag set. In the worst 1028 case, this would culminate in a segfault in the driver. 1029 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1127497 1030 1031 * Restore the gen4 workarounds for flickering rendering - a few cases still 1032 remain, as the root cause persists. 1033 https://bugs.freedesktop.org/show_bug.cgi?id=60402 1034 1035 * Double check that the device has KMS enabled before claiming. This allows 1036 X to gracefully fallback to VESA/fbdev rather than bailing out. 1037 https://bugs.freedesktop.org/show_bug.cgi?id=60987 1038 1039 * Fix the UXA render programs for projective transforms on Ivybridge. 1040 1041 1042 Release 2.21.2 (2013-02-10) 1043 =========================== 1044 Pass the brown paper bags, I need half a dozen or so. That seemingly 1045 innocuous build fix with xorg-1.13 happened to have the little side-effect 1046 of breaking glyph rendering with xorg-1.12 and older on 64-bit machines. 1047 1048 1049 Release 2.21.1 (2013-02-10) 1050 =========================== 1051 A fix for a potential GPU hang on 945gm (GMA950) and earlier chipsets, 1052 along with backporting SNA to the packages found in stable distributions 1053 like Debian 6.0 (Squeeze). 1054 1055 * Cleanup compilation warnings from deblint, thanks to Paul Menzel 1056 1057 * Minor build improvements by Damien Lespiau. 1058 1059 * Disable generating span geometry for non-rectilinear spans on gen4 1060 in order to work around and prevent one class of render corruption. 1061 1062 * Prevent cache thrashing and severe performance degradation on LLC 1063 machines for streaming texture updates. However, note the effect was 1064 only observed on just one particular laptop. 1065 1066 * Fix alignment of subsurface proxies for old chipsets. 1067 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1120108 1068 1069 * Repair build against Xserver-1.6 and contemporary packages. 1070 1071 1072 Release 2.21.0 (2013-02-01) 1073 =========================== 1074 A few new features: 1075 1076 * Enable render acceleration for Haswell GT1/GT2. 1077 1078 * Enable multi-threaded rasterisation of trapezoids and fallback composition 1079 1080 * Utilise a new kernel interface (v3.9) for processing relocations 1081 1082 along with a few older features from the 2.20.x series: 1083 1084 * PRIME support for hotplug GPUs and hybrid systems 1085 1086 * Support for IvyBridge GT1 machines, aka HD2500 graphics. 1087 1088 * Stable 830gm/845g support, at last! 1089 1090 As usual we have a large number of bug fixes since the last release: 1091 1092 * Prevent a stray relocation being left after a buffer is removed from 1093 a batch, leading to GPU hangs. 1094 1095 * Make the driver more robust against its own failures to submit batches 1096 by falling back to software rendering. 1097 1098 * Fix emission of scanline waits for secondary pipes on gen6/7. Otherwise 1099 you may encounter GPU hangs in MI_WAIT_FOR_EVENT. 1100 1101 * Fix a missing corner pixel when drawing rectangles with PolyLines 1102 https://bugs.freedesktop.org/show_bug.cgi?id=55484 1103 1104 * Don't try to use Y-tiling colour buffers with mesa/i915c as mesa 1105 doesn't support them and wil fallback to software rendering 1106 1107 * Ensure that any cached mmaps are invalidated for a SwapBuffers 1108 https://bugs.freedesktop.org/show_bug.cgi?id=60042 1109 1110 * Correctly handle the composition of rotated displays too large for the 1111 3D pipeline 1112 https://bugs.freedesktop.org/show_bug.cgi?id=60124 1113 1114 * Fix the computation of the planar video frame size 1115 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1104180 1116 1117 1118 Release 2.20.19 (2013-01-20) 1119 ============================ 1120 A quick release as the last broke USB DisplayLink slave outputs badly. The 1121 performance of those displays was unusable due to an inadvertent change that 1122 caused us to flush the entire scanout over the USB for every drawing 1123 operation. 1124 1125 * Implement the GNOME Build API. A couple of minor changes to make 1126 integrators and distributors lives a little easier, or at least more 1127 consistent. 1128 1129 * Correctly offset inplace trapezoids for subwindows, such as the GTK+ 1130 close button after it has a background image uploaded. 1131 1132 * Explicitly prevent ring-switching for synchronized rendering to 1133 scanouts (for vsync). 1134 1135 * Clip dirty region to slave pixmaps (otherwise UDL is nigh unusuable) 1136 https://bugs.freedesktop.org/show_bug.cgi?id=59539 1137 1138 1139 Release 2.20.18 (2013-01-16) 1140 ============================ 1141 A bunch of miscellaneous fixes for assertion failures and various 1142 performance regressions when mixing new methods for offloads, along with 1143 a couple of improvements for rendering with gen4. 1144 1145 * Remove use of packed unnormalized texture coordinates on gen4/5 as 1146 these GPUs do not support unnormalized coordinates in the sampler. 1147 1148 * Remove dependency upon x86 asm for cross-building to unsupported 1149 architectures. 1150 https://bugs.gentoo.org/show_bug.cgi?id=448570 1151 1152 * Apply damage around PRIME updates in the correct order. 1153 1154 * Correctly read the initial backlight level for when the user 1155 overrides UXA's choice of backlight controller. 1156 1157 * Throttle UXA and prevent it queuing work much faster than the GPU can 1158 complete it. This realised itself in impossible performance figures and 1159 the entire display freezing for several seconds whlist the GPU caught 1160 up. One side effect is that it also caused the DDX to consume more 1161 memory than was required as it could not recycle buffers quick 1162 enough, and in some cases this produces a marked improvement in 1163 performance. Also note on gen2/3 this requires a new libdrm [2.4.41] 1164 in order to prevent a bug causing the DDX to fallback to swrast. 1165 1166 Release 2.20.17 (2012-12-26) 1167 ============================ 1168 A minor update to prepare for co-operating with the kernel over managing 1169 stability on 830gm/845g. On this pair of chipsets, the kernel will perform 1170 an extra copy of the batchbuffer into reserved memory, which prevents them 1171 from randomly dying. However, that extra copy does have a noticeable 1172 impact upon throughput, so we also have a mechanism for userspace to 1173 opt-out of the kernel workaround and take responsibility for ensuring its 1174 batches are coherent. 1175 1176 * Build fixes against xorg-1.14 1177 https://bugs.freedesktop.org/show_bug.cgi?id=58552 1178 https://bugs.freedesktop.org/show_bug.cgi?id=58406 1179 1180 * Fixed the origin of cropped (textured) video windows (Xv and XvMC) 1181 https://bugs.freedesktop.org/show_bug.cgi?id=23033 1182 1183 * Fix potential corruption when using images larger than ~1GiB 1184 1185 1186 Release 2.20.16 (2012-12-15) 1187 ============================ 1188 Rejoice! We have found a trick to make 830gm/845g stable at long last. 1189 Ever since the switch to GEM and dynamic video memory, those early 1190 second generation chipsets have been plagued by instability. The lack of 1191 flushing cachelines from the CPU to GMCH was eventually solved by using 1192 an undocmented bit, but 830/845 were still hanging under memory pressure. 1193 These deaths were all due to garbage finding its way into the command 1194 streamer, and they go away if we take a leaf out of the original driver 1195 and never reuse those pages for anything else. So for the first time 1196 ever, I have been able to complete running the test suite on an 845g, 1197 even whilst thrashing the page and buffer caches! 1198 1199 * Run the SF stage as single-threaded on gen4 to workaround a few issues 1200 https://bugs.freedesktop.org/show_bug.cgi?id=57410 1201 1202 * Keep the scanout SURFACE_STATE separate to avoid overriding its 1203 memory access control on gen6/7 (i.e. writes to the scanout need to 1204 be kept out of the render cache) 1205 1206 * Tune batch flushing after an operation to an exported surface under a 1207 compositor. 1208 1209 * Make sure the source is on the CPU for inplace composition of trapezoids 1210 using the CPU 1211 https://bugs.freedesktop.org/show_bug.cgi?id=56825 1212 1213 * Immediately flush in the block hander after a split batch to reduce 1214 latency between the two halves of an operation. 1215 https://bugs.freedesktop.org/show_bug.cgi?id=51718 1216 1217 * Install a fallback config if we fail to install the desired config 1218 at VT switch (i.e. booting, after resume with 3 incompatible pipes on 1219 Ivybridge) 1220 1221 * Pin batches to avoid CS incoherence on 830/845 1222 https://bugs.freedesktop.org/show_bug.cgi?id=26345 1223 1224 1225 Release 2.20.15 (2012-12-03) 1226 ============================ 1227 And lo, enabling more of the common acceleration paths for gen4 revealed 1228 another lurking bug - something is wrong with how we prepare Y-tiling 1229 surfaces for rendering. For the time being, we can surreptiously disable 1230 them for gen4 and avoid hitting GPU hangs. 1231 1232 * Avoid clobbering the render state after failing to convert the 1233 operation to use the blitter. 1234 https://bugs.freedesktop.org/show_bug.cgi?id=57601 1235 1236 * Disable shadow tracking upon server regeneration, and so fix a crash 1237 if you restart the server whilst a RandR transform (e.g. rotation) is 1238 in effect. 1239 https://bugs.freedesktop.org/show_bug.cgi?id=52255 1240 https://bugs.freedesktop.org/show_bug.cgi?id=56608 1241 1242 1243 Release 2.20.14 (2012-11-26) 1244 ============================ 1245 The highlight of this release is gen4, from 965g to gm45. Quite an old 1246 bug surfaced in the shader assembly, sparking a chance to review a few 1247 design choices within that backend and experiment on fresh ways to 1248 workaround the remaining issues. 1249 1250 * Avoid using inplace XOR'ed uploads for very large buffers 1251 https://bugs.freedesktop.org/show_bug.cgi?id=57031 1252 1253 * Fix the gen4/5 opacity shader 1254 https://bugs.freedesktop.org/show_bug.cgi?id=57054 1255 1256 * Queue a pending vblank request after flip completion 1257 https://bugs.freedesktop.org/show_bug.cgi?id=56423 1258 1259 * Avoid migrating an uninitialised pixmap for use as a render source 1260 https://bugs.freedesktop.org/show_bug.cgi?id=47597 1261 1262 * Improve handing of texture fallbacks for 830/845. 1263 https://bugs.freedesktop.org/show_bug.cgi?id=57392 1264 1265 1266 Release 2.20.13 (2012-11-11) 1267 ============================ 1268 Nothing but bug fixes. Many thanks to everyone who took the time to 1269 report their issues, and for their help in improving the driver. 1270 1271 * Sanity check the platform probe points to our expected i915 device 1272 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1069031 1273 1274 * Prevent 16-bit overflow for computing the sample area to upload of 1275 sources for render operations 1276 https://bugs.freedesktop.org/show_bug.cgi?id=56324 1277 1278 * Clamp the drawable box for migration to prevent 16-bit overflow 1279 https://bugs.freedesktop.org/show_bug.cgi?id=56591 1280 1281 * Disable RandR hotplug events if Xinerama is enabled and thereby prevent 1282 a crash upon hotplug 1283 https://bugs.freedesktop.org/show_bug.cgi?id=55260 1284 1285 * Call ValidatePicture before attempting to flatten the alphamaps 1286 https://bugs.freedesktop.org/show_bug.cgi?id=56367 1287 1288 * Clip the trapezoid correctly if it ends on the boundary pixel 1289 https://bugs.freedesktop.org/show_bug.cgi?id=56395 1290 1291 * Make sure the pipeline choice is propagated to the scanline wait 1292 across a batch flush 1293 https://bugs.freedesktop.org/show_bug.cgi?id=47597 1294 1295 * Set the valid drawable box when choosing placement of BLT composite ops 1296 https://bugs.freedesktop.org/show_bug.cgi?id=47597 1297 1298 * Prevent use-after-free when promoting a partial-GPU bo to a full-GPU bo 1299 https://bugs.freedesktop.org/show_bug.cgi?id=56591 1300 1301 * gen4 opacity spans require the per-rectangle workaround 1302 https://bugs.freedesktop.org/show_bug.cgi?id=55500 1303 1304 * Prevent use of invalid damage pointers when redirecting rendering 1305 https://bugs.freedesktop.org/show_bug.cgi?id=56785 1306 1307 1308 Release 2.20.12 (2012-10-20) 1309 ============================ 1310 More bug reports, more bug fixes! Perhaps the headline feature is 1311 that with a secure batches, coming to a 3.8 kernel near you, we may 1312 finally have the ability to perform updates to the scanout synchronized 1313 to the refresh rate on later SandyBridge and IvyBridge chipsets. It comes 1314 at quite a power cost as we need to keep the GPU out of its power saving 1315 modes, but it should allow legacy vsync to function at last. But this 1316 should allow us to address a longstanding issue with tearing on 1317 SandyBridge+. 1318 1319 * Fix component-alpha rendering on IvyBridge, for example subpixel 1320 antialiased glyphs. 1321 https://bugs.freedesktop.org/show_bug.cgi?id=56037 1322 1323 * Flush before some "pipelined" state changes on gen4. The evidence is 1324 that the same flushes as required on gen5+ are also required for gen4. 1325 https://bugs.freedesktop.org/show_bug.cgi?id=55627 1326 1327 * Prevent a potential crash when forcing a stall on a busy CPU bo 1328 https://bugs.freedesktop.org/show_bug.cgi?id=56180 1329 1330 [Release 2.20.11 contained a typo causing UXA to fail immediately.] 1331 1332 Release 2.20.10 (2012-10-14) 1333 ============================ 1334 The last couple of weeks have been fairly retrospective, a dive into 1335 prehistory tidying up the earlier generations which lay languishing as 1336 the core progressed and lead to a number of annoying core bugs being 1337 fixed. 1338 1339 * Release DRM master earlier during shutdown so switching between 1340 multiple X servers works automatically. 1341 https://bugs.freedesktop.org/show_bug.cgi?id=55446 1342 1343 * Suppress error propagation from DRI2GetMSC and behave as if the pipe 1344 was simply off to avoid unexpected errors in the clients 1345 https://bugs.freedesktop.org/show_bug.cgi?id=55395 1346 1347 * A few fixes to i8xx batch emission, ensuring that the GPU is always 1348 in a valid state. 1349 https://bugs.freedesktop.org/show_bug.cgi?id=55455 1350 1351 * Prevent a use-after-free during UXA shutdown due to inspecting 1352 the glamor flags after the glamor interface had been freed. 1353 1354 * Prevent a crash combining TearFree and rotations. 1355 https://bugs.freedesktop.org/show_bug.cgi?id=55527 1356 1357 * Correct a missing damage upload along PutImage after using the CPU bo 1358 as a source for the GPU. 1359 https://bugs.freedesktop.org/show_bug.cgi?id=55508 1360 1361 * Fix compilation for older glibc without O_CLOEXEC 1362 https://bugs.freedesktop.org/show_bug.cgi?id=55577 1363 1364 * Fix out-of-tree builds failing to recompile the gen4 assemblies 1365 https://bugs.freedesktop.org/show_bug.cgi?id=55645 1366 1367 * Fix non-standard build host configuration handling for intel-gen4asm 1368 https://bugs.freedesktop.org/show_bug.cgi?id=55646 1369 1370 * Fix a potential batch buffer overflow when replacing the last BLT fill 1371 operation with a copy 1372 https://bugs.freedesktop.org/show_bug.cgi?id=55700 1373 1374 * Flush the render pipeline more frequently on Ironlake as not all 1375 pipelined state changes are. 1376 https://bugs.freedesktop.org/show_bug.cgi?id=51422 1377 1378 * Detect when we need to read the destination for the background raster 1379 op during fallbacks. 1380 https://bugs.freedesktop.org/show_bug.cgi?id=55810 1381 1382 * Avoid a potential deference of an invalid CPU mmap after doing an 1383 inplace tiled upload. 1384 https://bugs.freedesktop.org/show_bug.cgi?id=55812 1385 1386 * Prevent sign extension when packing the upload data for CopyPlane 1387 https://bugs.freedesktop.org/show_bug.cgi?id=55823 1388 1389 * Fix some render corruption with a UDL slave output and pageflipping 1390 1391 1392 Release 2.20.9 (2012-09-29) 1393 =========================== 1394 And so it came to pass that a critical bug was uncovered in UXA. The 1395 kernel does not like to pageflip when the pipe is off, yet due to the 1396 delayed nature of a pageflip and the relaxed checking performed by UXA, 1397 we could request a pageflip after turning off the display (DPMS). The 1398 kernel rejected that pageflip and the error handling path failed to 1399 restore sanity, and when the screen came back it was stuck on the image 1400 seen before it went to sleep. (Note that there are also some related 1401 kernel bugs, but this update should prevent the most conspicious of the 1402 freezes.) Many thanks to Timo Aaltonen for his efforts in tracking down 1403 the issue. 1404 1405 In other news: 1406 1407 * Prepare for xorg-1.14, the api is being tweaked again. 1408 1409 * Handle early FreeScreen in UXA. 1410 https://bugs.freedesktop.org/show_bug.cgi?id=55346 1411 1412 * Reenable XvMC support 1413 1414 * Do not replace the GPU bo when uploading into the shadow/CPU copy 1415 https://bugs.freedesktop.org/show_bug.cgi?id=54978 1416 1417 * Fix use of an uninitialised GC when drawing glyphs to a depth=1 pixmap 1418 1419 1420 Release 2.20.8 (2012-09-16) 1421 =========================== 1422 Another new small feature, another new release. And a few more bugs 1423 fixed as well! But what is this new feature, do I hear you ask? Why, it 1424 is nothing less than enabling the ValleyView SDV! The lucky person to 1425 have their hands on one will now be able to enjoy X in full TechniColor. 1426 1427 For the rest of us, a few more bugs were fixed with interesting 1428 combinations of software and rendering patterns. 1429 1430 * Add an extra layer of defence against trying to use a non-GEM device 1431 with UXA. This should already be taken care of with the new probe, 1432 but the extra sanity check already existed in the code but was doing 1433 nothing. 1434 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/962892 1435 1436 * Fix computation of valid CRTCs bitmask for ZaphodHead 1437 Some systems can only handle certain outputs on certain pipes 1438 (Screens), and this information was not being propagated through to X 1439 and randr correctly, breaking valid configurations and not detecting 1440 invalid configurations correctly. 1441 1442 * Disable global glyph caching with ZaphodHeads. 1443 The glyph privates need to be Screen private, but at the moment are 1444 global leading to conflicts and invalid rendering with multiple heads. 1445 https://bugs.freedesktop.org/show_bug.cgi?id=54707 1446 1447 * Prevent direct read back of unmappable buffers 1448 https://bugs.freedesktop.org/show_bug.cgi?id=54808 1449 1450 * Tile large uploads whilst replacing the alpha channel 1451 https://bugs.freedesktop.org/show_bug.cgi?id=54808 1452 1453 * Correct the source offset when converting a RENDER composite 1454 operation into a BLT composite operation. 1455 https://bugs.freedesktop.org/show_bug.cgi?id=54868 1456 1457 * Correct a minor typo in flattening alphamaps which caused the 1458 replacement pixmap to often end up with a height of zero. 1459 https://bugs.gentoo.org/show_bug.cgi?id=434860 1460 1461 * Don't discard the CPU damage if only part of is being replaced. 1462 This is most evident when combining software renders like Opera with 1463 accelerated rendering. 1464 https://bugs.freedesktop.org/show_bug.cgi?id=54937 1465 1466 Release 2.20.7 (2012-09-08) 1467 =========================== 1468 Continuing the flurry of releases, this week saw the release of 1469 xorg-1.13 bringing with it the first steps towards hotpluggable gpu 1470 support and the ability to offload DRI rendering onto other GPUs. In 1471 light of that advance, this release includes the support code by Dave 1472 Airlie to integrate PRIME into xf86-video-intel and make those new 1473 features available. 1474 1475 Aside from landing PRIME, a few other bugs were fixed since 2.20.6: 1476 1477 * Fix framebuffer leak on server regeneration 1478 1479 * Fix texture cache flushing on IvyBridge and Kwin with plastique 1480 https://bugs.freedesktop.org/show_bug.cgi?id=54488 1481 1482 * Redirect large solid fills on SandyBridge+. By large I mean greater 1483 than 8192 or 16384 pixels on SandyBridge and IvyBridge respectively. 1484 https://bugs.freedesktop.org/show_bug.cgi?id=54134 1485 1486 * Fix up backlight option handling in the manpage and uxa. 1487 https://bugs.freedesktop.org/show_bug.cgi?id=54397 1488 1489 * Unbreak ZaphodHeads. 1490 https://bugs.freedesktop.org/show_bug.cgi?id=52438 1491 1492 Release 2.20.6 (2012-09-02) 1493 =========================== 1494 A serious bug that caused a crash on SandyBridge and IvyBridge when 1495 mixing CPU and GPU operations on the same buffer, and an annoyance from 1496 bad scheduling of windowed swapbuffer updates causing low framerates and 1497 jitter. Plus the usual smattering of assertion fixes and a long standing 1498 issue with incoherent page access to a streaming buffer. 1499 1500 * Low frame rates in Blobby Valley when "fullscreen" 1501 https://bugs.freedesktop.org/show_bug.cgi?id=54274 1502 1503 * Incoherent concurrent access with the CPU and GPU 1504 https://bugs.freedesktop.org/show_bug.cgi?id=51422 1505 https://bugs.freedesktop.org/show_bug.cgi?id=52299 1506 1507 * Add Option "Backlight" to override automatic selection of the 1508 backlight interface. 1509 1510 * Avoid overwriting the composite operation info when testing if we 1511 can transfer the operation to the BLT. 1512 1513 Release 2.20.5 (2012-08-26) 1514 =========================== 1515 Another silly bug found, another small bugfix release. The goal was for 1516 the driver to bind to all Intel devices supported by the kernel. 1517 Unfortunately we were too successful and started claiming Pouslbo, 1518 Medfield and Cedarview devices which are still encumbered by propietary 1519 IP and not supported by this driver. 1520 1521 Bugs fixed since 2.20.4: 1522 1523 * Only bind to Intel devices using the i915 kernel module 1524 1525 * Regression in the bitmap-to-region code, e.g. icewm window buttons 1526 https://bugs.freedesktop.org/show_bug.cgi?id=53699 1527 1528 Release 2.20.4 (2012-08-18) 1529 =========================== 1530 Continuing the small bugfix releases, the only real feature is initial 1531 enabling for Haswell for the purpose of rendering verification and 1532 validation - by no means is it complete! 1533 1534 Bugs fixed since 2.20.3: 1535 1536 * Some potential errors along failure paths found by a static analyser 1537 with the help of Zdenek Kablac. 1538 1539 * Eliminate zero-sized rectangles from PolyFillRectangles as the code 1540 assumes that they did not exist and so caused corruption. 1541 1542 * Remove the UXA warning for failing to tile the front buffer if it is 1543 disallowed by hardware, and so expected. 1544 1545 * Fix the validation of the XV pipe parameter. 1546 1547 * Fix 8x8 tiled pattern fills 1548 https://bugs.freedesktop.org/show_bug.cgi?id=53353 1549 1550 * Fix compile failure when using --with-builderstring 1551 1552 * Restore w/a flush for gen4 fill/copy/video, fortunately rare 1553 operations as at least for fill/copy we prefer to use the BLT. 1554 https://bugs.freedesktop.org/show_bug.cgi?id=53119 1555 1556 * Restore preferred use of the RENDER ring for SNB+ DRI copies. 1557 1558 Release 2.20.3 (2012-08-04) 1559 =========================== 1560 Just a minor bugfix for gen4 chipsets (965gm, gm45 and friends) that 1561 crept into 2.20.2. As an added bonus, the pessimistic workaround for a 1562 GPU hang on gen4 has been relaxed and the shaders have been overhauled 1563 which should pave the way to eliminating the last of the uncommon CPU 1564 operations, along with immediately realising a small perforamnce 1565 improvement. 1566 1567 Bugs fixed since 2.20.2: 1568 1569 * Update DPMS bookkeeping after modeset 1570 https://bugs.freedesktop.org/show_bug.cgi?id=52142 1571 1572 * Avoid overlapping gpu/cpu damage after ignoring cpu damage in the 1573 consideration of placement for the operation. 1574 1575 * Enable acceleration by default on 830gm/845g. The GMCH on this pair 1576 of chipsets is notoriously incoherent, so the GPU is almost certainly 1577 going to hang at some point, though unlikely to hang the system and 1578 should automatically disable acceleration (and thence behave 1579 identically as if the acceleration was disabled from the start). 1580 Option "NoAccel" can be used to disable all 2D acceleration and 1581 Option "DRI" can be used to disable all 3D acceleration. 1582 https://bugs.freedesktop.org/show_bug.cgi?id=52624 1583 1584 * Fix vertex bookkeeping for gen4 that was causing corruption in the 1585 command stream. 1586 1587 Release 2.20.2 (2012-07-27) 1588 =========================== 1589 For the last 9 months, since 2.16.901, we have been shipping a driver that 1590 does not work on IvyBridge GT1 systems (HD2500 graphics); we were telling 1591 the GPU to use an invalid number of threads for the pixel shader and this 1592 in turned caused the GPU to hang. 1593 1594 Also fixed since the last release just a few days ago: 1595 1596 * Support for the gmux backlight controller on Apple laptops 1597 https://bugs.freedesktop.org/show_bug.cgi?id=52423 1598 1599 * Fix X -configure not to list this driver as matching any Intel device, 1600 just the VGA class devices will do! 1601 1602 * A crash in SNA when repeatedly switching xrandr rotations 1603 1604 * Corruption in SNA observed in kwin on IvyBridge 1605 https://bugs.freedesktop.org/show_bug.cgi?id=52473 1606 1607 Release 2.20.1 (2012-07-22) 1608 =========================== 1609 A week in, grab the brown paper bags, for it is time to reveal a couple 1610 of critical bugs that spoilt the 2.20.0 release. 1611 1612 Firstly we have the restoration of DRI for i810. I am sure that the 1613 solitary user will be overjoyed in a couple of years when a new xserver 1614 is forced upon him. That enjoyment will be short-lived when as no actual 1615 acceleration remains, not even shadow, for the chipset. 1616 1617 Perhaps a little more wildly felt, I hope!, will be that the SNA 1618 fallbacks were broken on 64-bit machines if they required clipping. One 1619 little misplaced cast of a pointer, and the screen is filled with 1620 corruption. 1621 1622 Among the other tweaks this week: 1623 1624 * A bug affecting gen4 handling of trapezoids was fixed, and CPU 1625 overhead reduced. 1626 https://bugs.freedesktop.org/show_bug.cgi?id=52158 1627 1628 * A fix for a bug causing corruption of a DRI2 unredirected client 1629 window that was resized whilst under a compositor. 1630 1631 * Support for snoopable buffers on non-LLC architectures, coming to 1632 a future kernel. The aim to accelerate transfers between the CPU 1633 and the GPU, in particular to dramatically improve readback 1634 performance, and to further minimise clflushes. 1635 1636 * Improvement to the composite performance on GT2 SandyBridge and 1637 IvyBridge devices, in particular the render copy is significantly 1638 improved. 1639 1640 * Improved handling for when acceleration is disabled, including 1641 permitting DRI2 to remain supported even if the X server believes 1642 the GPU wedged. 1643 1644 * Shadow support was dropped from UXA as it was neither complete nor 1645 correct, use SNA instead. 1646 1647 Release 2.20.0 (2012-07-15) 1648 =========================== 1649 First the big news, a new acceleration method that aims to be faster and 1650 consume far less CPU than UXA is now available for selection at runtime. 1651 This snazzy new architecture can be selected through use of 1652 Option "AccelMethod" "sna" 1653 in your xorg.conf. Whilst it has been under development for some time, it 1654 has not yet had the same degree of widespread testing of UXA, so tread 1655 lightly. Try it and if you spot anything that can be improved, please do 1656 report a bug. 1657 1658 Otherwise we have the usual smattering of bug fixes for UXA: 1659 1660 * Use a white source whilst adding glyphs to the glyph mask 1661 (This fixes blank glyphs if using a font that mixes ARGB and A glyphs.) 1662 1663 * Avoid fallbacks for glyph-to-dst in e.g. gnome-terminal 1664 https://bugs.freedesktop.org/show_bug.cgi?id=50508 1665 1666 * Force unused outputs off when VT switching 1667 https://bugs.freedesktop.org/show_bug.cgi?id=50772 1668 1669 * Copy the fbcon across to the Screen pixmap at startup. 1670 (This patch has been kicking around in the distributions for years.) 1671 1672 * Many missed malloc failures checks and forgotten frees found by a static 1673 analyzer. Thanks Zdenek Kabelac! 1674 1675 * Leak of the back buffer when terminating an application after pageflipping 1676 https://bugs.freedesktop.org/show_bug.cgi?id=50670 1677 1678 * Double check that the pipe is on before emitting a WAIT_ON_EVENT. 1679 In conjunction with an uptodate kernel, this should eliminate any 1680 hangs when changing resolutions or adding/removing displays. 1681 https://bugs.freedesktop.org/show_bug.cgi?id=50668 1682 1683 * Update to new Xorg APIs. Future proofing for the next generation of 1684 hotplug Xorg display servers. 1685 1686 Many thanks to everyone who has reported a bug and otherwise helped to 1687 improve the driver. 1688 1689 Release 2.19.0 (2012-04-29) 1690 =========================== 1691 More stability fixes for UXA and support for another variant of IvyBridge. 1692 Given the severity of the stability fixes, I strongly recommend everybody 1693 to upgrade to 2.19.0. 1694 1695 * Prevent waiting on scanlines whilst not in control of the VT and therefore 1696 whilst referencing foreign CRTC configurations. 1697 1698 * Pixmap (and bo leak) during fallback glyph composition 1699 1700 * Remove broken acceleration for rendering glyphs directly upon the 1701 destination pixmap, exposed by cairo-1.12.0 (and coincidentally fix 1702 another Pixmap leak upon fallback handling). 1703 1704 * Add support for Ivy Bridge GT2 Server chipset [PCI id 0x016a] 1705 1706 * Remove broken damage flushing with CompositeRectangles 1707 https://bugs.freedesktop.org/show_bug.cgi?id=32547 1708 1709 * Fix crash upon server start with multiple monitors 1710 https://bugs.freedesktop.org/show_bug.cgi?id=47395 1711 1712 * Fix composition issues resulting from overly aggressive Pixmap reuse 1713 https://bugs.freedesktop.org/show_bug.cgi?id=47345 1714 1715 Release 2.18.0 (2012-02-24) 1716 =========================== 1717 Time passes, a few more bugs have crept out of the woodwork that are a 1718 compelling reason to update. 1719 1720 Bugs fixed in this release (compared to 2.17.0) 1721 ----------------------------------------------- 1722 1723 * Limit maximum object size so that all of the source, mask and 1724 destination can be mapped into the aperture simultaneously by basing the 1725 limit on the mappable aperture size rather than the size of the total 1726 GATT. 1727 1728 * Incorrect clipping of polygons 1729 https://bugs.freedesktop.org/show_bug.cgi?id=43649 1730 Regression from 2.15.901 1731 1732 * Limit number of VMA cached to avoid hitting the per-process VMA limit 1733 There still is a residual bug in that we seem to have so many objects 1734 floating around in the first place and that still leads to exhaustion 1735 of system limits. 1736 https://bugs.freedesktop.org/show_bug.cgi?id=43075 1737 https://bugs.freedesktop.org/show_bug.cgi?id=40066 1738 1739 * Latency in processing user-input during continuous rendering 1740 1741 Release 2.17.0 (2011-11-16) 1742 ============================== 1743 A few months have passed, and we have accumulated a surprising number of 1744 bug fixes. Oops! We would strongly encourage everyone to upgrade. 1745 1746 Bugs fixed in this snapshot (compared to 2.16.902) 1747 -------------------------------------------------- 1748 1749 * Video clobbering composite batch state 1750 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=635953 1751 1752 Snapshot 2.16.902 (2011-11-13) 1753 ============================== 1754 This is the second release candidate in preparation for the upcoming 1755 2.17.0 release. We will appreciate any feedback we can get from 1756 testing of this snapshot, and thanks to everyone who tested and reported 1757 upon issues in the last snapshot. 1758 1759 A very old bug demonstrating that nobody has ever used alpha maps, and a 1760 couple of more recent mistakes were found. 1761 1762 Bugs fixed in this snapshot (compared to 2.16.901) 1763 -------------------------------------------------- 1764 1765 * Incorrect reuse of surface bindings within a batch for multiple formats 1766 https://bugs.freedesktop.org/show_bug.cgi?id=40926 1767 1768 * Nothing was rendered for text with procedural sources 1769 https://bugs.freedesktop.org/show_bug.cgi?id=31819 1770 1771 * Handle fallbacks involving alpha maps 1772 1773 Snapshot 2.16.901 (2011-10-30) 1774 ============================== 1775 This is the first release candidate in preparation for the upcoming 1776 2.17.0 release. We will appreciate any feedback we can get from 1777 testing of this snapshot. 1778 1779 The basis of this release are to push out a couple of critical stability 1780 fixes for SandyBridge and IvyBridge. There is very little else to see 1781 here. Those 200+ other commits do not exist... 1782 1783 Bugs fixed in this snapshot (compared to 2.16.0) 1784 -------------------------------------------------- 1785 1786 * Workaround blitter hang on SandyBridge and IvyBridge 1787 https://bugzilla.kernel.org/show_bug.cgi?id=27892 1788 https://bugs.freedesktop.org/show_bug.cgi 1789 1790 * Workaround pipe control issues on SandyBridge 1791 1792 * Use correct maximum PS thread count on IvyBridge 1793 1794 * Protect against failed pixmap allocation for XV 1795 https://bugs.freedesktop.org/show_bug.cgi?id=40439 1796 1797 Release 2.16.0 (2011-08-09) 1798 ============================== 1799 A new quarter, a new release! The key feature of this release, looking past 1800 the bug fixes, is the enabling of IvyBridge acceleration. We have also fixed 1801 many bugs and graphical glitches and would encourage everyone to upgrade. 1802 1803 Bugs fixed in this snapshot (compared to 2.15.901) 1804 -------------------------------------------------- 1805 1806 * Build fix for xserver-1.7.7 1807 1808 Snapshot 2.15.901 (2011-07-30) 1809 ============================== 1810 This is the first release candidate in preparation for the upcoming 1811 2.16.0 release. We will appreciate any feedback we can get from 1812 testing of this snapshot. 1813 1814 The highlight of this snapshot is the full enabling of IvyBridge with 1815 acceleration for Render and Xv, along with handling of the shared render 1816 buffer allocations required for Mesa. Also of note is that deep-color 1817 support is enabled (for all chipsets), which allows you to drive your 1818 30-bit monitor at its native colour depth. 1819 1820 Bugs fixed in this snapshot (compared to 2.15.0) 1821 -------------------------------------------------- 1822 1823 * Misuse of the Resource database causing crashes after DRI clients close 1824 https://bugs.freedesktop.org/show_bug.cgi?id=37700 1825 1826 * Crash on large strings 1827 https://bugs.freedesktop.org/show_bug.cgi?id=36860 1828 1829 * Incorrect rendering for some core drawing operations 1830 http://bugs.freedesktop.org/show_bug.cgi?id=28768 1831 http://bugs.freedesktop.org/show_bug.cgi?id=28798 1832 http://bugs.freedesktop.org/show_bug.cgi?id=28908 1833 http://bugs.freedesktop.org/show_bug.cgi?id=29401 1834 1835 * Crash in Xv due to insufficient checks on batch space 1836 https://bugs.freedesktop.org/show_bug.cgi?id=36319 1837 1838 Release 2.15.0 (2011-04-14) 1839 ============================== 1840 We are pleased to announce this major release of the xf86-video-intel 1841 driver, roughly on schedule at 3 months since 2.14.0. With the many bug 1842 fixes in this release, we encourage everyone to upgrade to 2.15. 1843 1844 The priority for this quarter has been simply to be unexciting and stabilise 1845 the driver further, seeking to capitalise upon the improvements elsewhere 1846 in the stack. 1847 1848 Bugs fixed in this snapshot (compared to 2.14.903) 1849 -------------------------------------------------- 1850 1851 * Turn off relaxed fencing by default for older chipsets 1852 This was continuing to destabilize those system, so for the release 1853 we disabled the feature. If you wish to help us debug this, you can 1854 re-enable the optimisation with Option "RelaxedFencing" "True". 1855 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=36147 1856 1857 * Build fix for xserver-1.7.7 1858 1859 * KDE glitches on SNB 1860 [Technically fixed in the previous snapshot, but I'm really pleased 1861 that this got fixed in time for the release!] 1862 https://bugs.freedesktop.org/show_bug.cgi?id=35808 1863 1864 1865 Snapshot 2.14.903 (2011-04-11) 1866 ============================== 1867 This is the third release candidate in preparation for the upcoming 1868 2.15.0 release. We will appreciate any feedback we can get from 1869 testing of this snapshot. 1870 1871 There was a bit of churn since 2.14.902 as a potential fix for a 1872 performance regression was tried but had to reverted when it was found to 1873 cause glitches running Compiz on SandyBridge. Otherwise, there were just a 1874 couple of fixes for building against old xservers and running on an 1875 obscure chipset. 1876 1877 Bugs fixed in this snapshot (compared to 2.14.902) 1878 -------------------------------------------------- 1879 1880 * Prevent issuing an invalid scanline wait command 1881 https://bugs.freedesktop.org/show_bug.cgi?id=35576 1882 1883 * The 946GZ in not a 945, but a 965. 1884 https://bugs.freedesktop.org/show_bug.cgi?id=35854 1885 1886 * Fix tile sizes for gen2 (finally). 1887 1888 * Allow building of recent dri2 changes against old xservers. 1889 1890 1891 Snapshot 2.14.902 (2011-03-29) 1892 ============================== 1893 This is the second release candidate in preparation for the upcoming 1894 2.15.0 release. We will appreciate any feedback we can get from 1895 testing of this snapshot. 1896 1897 As befits testing of release candidates, no major regression was found and 1898 a couple more bugs have been fixed. 1899 1900 Bugs fixed in this snapshot (compared to 2.14.901) 1901 -------------------------------------------------- 1902 1903 * Clients disappearing with pending swaps 1904 1905 * Incorrect clipping of Xv output on i915 across extended desktops 1906 https://bugs.freedesktop.org/show_bug.cgi?id=35346 1907 1908 * Introduction of a LinearFramebuffer option. (Defaults to tiled for 1909 performance and power saving.) 1910 1911 1912 Snapshot 2.14.901 (2011-03-02) 1913 ============================== 1914 This is the first release candidate in preparation for the upcoming 1915 2.15.0 release. We will appreciate any feedback we can get from 1916 testing of this snapshot. 1917 1918 Still no further along my grandiose plans to improve Render performance, 1919 aside from the performance tuning lower in the stack, instead we have had 1920 a steady stream of bug fixes. 1921 1922 Bugs fixed in this snapshot (compared to 2.14.0) 1923 ------------------------------------------------ 1924 1925 * Green pixels within partially off-screen video playback 1926 https://bugs.freedesktop.org/show_bug.cgi?id=24767 1927 1928 * Defer creation of the glyph cache to generation startup 1929 https://bugs.freedesktop.org/show_bug.cgi?id=33412 1930 1931 * Incorrect maximum addresses for video decoder state 1932 https://bugs.freedesktop.org/show_bug.cgi?id=34017 1933 1934 * Failure to handle oversized temporary surfaces 1935 https://bugs.freedesktop.org/show_bug.cgi?id=34399 1936 1937 * Relaxed tiling corruption on gen2 1938 1939 * Crash when destroying a foreign DRI drawable 1940 https://bugs.freedesktop.org/show_bug.cgi?id=34787 1941 1942 1943 Release 2.14.0 (2011-01-07) 1944 =========================== 1945 We are pleased to announce this major release of the xf86-video-intel 1946 driver, on schedule at 3 months since 2.13.0. With the many bug fixes 1947 in this release, we encourage everyone to upgrade to 2.14. 1948 1949 The most notable feature of this release is the inclusion of acceleration 1950 support, both RENDER and XVIDEO, for Sandy Bridge; note that this requires 1951 a 2.6.37 kernel. In improving the acceleration code paths to support Sandy 1952 Bridge, we were also able to improve the performance of the general i965+ 1953 RENDER acceleration. For example on i3, glyph (aa10 and rgb10) performance 1954 is about 3x faster, as is performing small copies between windows, with the 1955 improvement becoming negligible once you hit around 100 pixels square. 1956 1957 1958 Snapshot 2.13.903 (2010-01-04) 1959 ============================== 1960 This is the second release candidate in preparation for the upcoming 1961 2.14.0 release, and if no showstoppers turn up in wider testing will 1962 become the next release. Besides the usual bug fixes, we've included 1963 patches by Mario Kleiner to improve vblank handing which both improve the 1964 timing accuracy and remove a few potential races -- provided you also 1965 have the corresponding fixes in the kernel. 1966 1967 Bug fixes 1968 --------- 1969 1970 * Crash on hot-unpluging with an active fullscreen GL application, e.g. a 1971 compositing WM or video player 1972 https://bugs.freedesktop.org/show_bug.cgi?id=32770 1973 1974 * Freeze upon maximising client-side software renderers, e.g. flash. 1975 https://bugs.freedesktop.org/show_bug.cgi?id=31367 1976 1977 * Fix confusion over G35 generation 1978 https://bugs.freedesktop.org/show_bug.cgi?id=32478 1979 1980 1981 Snapshot 2.13.902 (2010-12-10) 1982 ============================== 1983 This is the first release candidate in preparation for the upcoming 1984 2.14.0 release. Sandybridge support should be now be ready for use, 1985 and we will appreciate any feedback we can get from this snapshot. 1986 Improving the code base for Sandybridge should also have had knock 1987 on effects for earlier chips as well, in particular Ironlake and to 1988 a lesser extent i965. 1989 1990 New requirements compared to 2.13 1991 --------------------------------- 1992 * Librdrm >= 2.4.23 1993 1994 Bug fixes 1995 --------- 1996 1997 * Crash after failing to allocate memory 1998 https://bugs.freedesktop.org/show_bug.cgi?id=31487 1999 2000 * EFAULT during pwrite 2001 https://bugs.freedesktop.org/show_bug.cgi?id=29752 2002 2003 * Mark outputs as on and restore backlight after mode-set 2004 2005 * A hang with i965+ with newer kernels. 2006 2007 2008 Snapshot 2.13.901 (2010-11-05) 2009 ============================== 2010 This is an intermediate snapshot of ongoing driver development. The 2011 primary purpose of this snapshot is to capture some recent 2012 improvements, (particularly in Sandybridge support), for further 2013 testing. 2014 2015 Release 2.13.0 (2010-09-30) 2016 =========================== 2017 We are pleased to announce this major release of the xf86-video-intel 2018 driver, on schedule at 3 months since 2.12.0.

This fixed a 2365 regression that showed up recently (only in these release candidates). 2366 2367 Fix recent regression leading to corruption under compiz: 2368 2369 https://bugs.freedesktop.org/show_bug.cgi?id=26814 2370 2371 Further DRI2 improvements/fixes from Mario Kleiner and Jesse Barnes, 2372 (including support for SwapBuffers request with divisor != 0). 2373 2374 Fix build against X server 1.6 branch. 2375 2376 Avoid flooding logs after an error occurs. 2377 2378 And dramatic code cleanups 2379 -------------------------- 2380 Eric Anholt removed several cases of old, useless code, (conditions 2381 that could not occur now that we require KMS, etc.). 2382 2383 Daniel Vetter eliminated piles of code by modernizing the XvMC 2384 memory-management and completely removing the old i830_memory 2385 allocator (i830_allocate_memory, i830_free_memory), etc. 2386 2387 Snapshot 2.10.901 (2010-02-26) 2388 ============================== 2389 The most significant new feature of this release is support for new 2390 DRI2 APIs, allowing page flipping to occur for swaps that are 2391 full-screen and not rotated. 2392 2393 Some significant bug fixes 2394 -------------------------- 2395 * Avoid fallback due to failing to extract pixel value from an 2396 alpha-only solid, (this fix eliminated 1 second from Mobilin boot 2397 time). 2398 2399 https://bugs.freedesktop.org/show_bug.cgi?id=26189 2400 2401 * Handle full-height blits without tearing in CopyRegion 2402 2403 https://bugs.freedesktop.org/show_bug.cgi?id=22475 2404 2405 Several other fixes and cleanups are included as well, (including the 2406 removal of stale utility code that is now maintained in the separate 2407 intel-gpu-tools module). 2408 2409 Release 2.10.0 (2010-01-04) 2410 =========================== 2411 New requirements of 2.10 compared to 2.9 2412 ---------------------------------------- 2413 * Linux kernel with kernel-modesetting (KMS) 2414 2415 All user-modesetting code has now been removed from the driver. 2416 We highly recommend kernel version 2.6.32 or later. 2417 2418 * Libdrm >= 2.4.16 2419 2420 New features in 2.10 compared to 2.9 2421 ------------------------------------ 2422 * New driver debugging options available in xorg.conf 2423 (DebugFlushBatches, DebugFlushCaches, DebugWait). See "man intel" 2424 for more details. 2425 2426 * Video overlay support with KMS. This currently requires Linux 2427 2.6.33, but a backport to 2.6.32 is available here: 2428 2429 http://gitorious.org/daniel-s-linux-stuff/linux-kernel/commits/intel-kms-overlay-for-2.6.32 2430 2431 Notable fixes in 2.10 compared to 2.9 2432 ----------------------------------- 2433 * Fix crash when XRenderComposite is called with a -1 value for 2434 width/height, (crash at login when using compiz). 2435 2436 http://bugs.freedesktop.org/show_bug.cgi?id=24724 2437 2438 * Fix to support larger extended desktops, (such as a 2560x1600 plus a 2439 1920x1200 monitor). 2440 2441 2442 * Fix glyph corruption due to insufficient cache flushing: 2443 2444 https://bugs.freedesktop.org/show_bug.cgi?id=24315 2445 2446 Several other correctness and performance fixes are also included. 2447 2448 Note: The driver code of the 2.10.0 release is identical to that of 2449 the 2.9.99.901 release candidate. The only changes in 2.10.0 compared 2450 to 2.9.99.902 are a minor change to the configure script, and some 2451 small updates to the documentation. 2452 2453 Snapshot 2.9.99.902 (2009-12-10) 2454 ================================ 2455 This is the second release candidate in preparation for the upcoming 2456 2.10.0 release. We will appreciate any feedback we can get from 2457 testing of this snapshot to improve the 2.10.0 release. 2458 2459 Compared to the previous snapshot, this snapshot now correctly 2460 verifies that libdrm 2.4.16 (or newer) is available. The previous 2461 snapshot also required libdrm 2.4.16 for correct functionality, but 2462 neglected to notify the user of this at configure, compile, or install 2463 time and would instead simply fail to run. 2464 2465 Snapshot 2.9.99.901 (2009-11-30) 2466 ================================ 2467 This is the first release candidate in preparation for the upcoming 2468 2.10.0 release. We will appreciate any feedback we can get from 2469 testing of this snapshot to improve the 2.10.0 release. 2470 2471 With this snapshot, the xf86-video-intel driver requires kernel 2472 modesetting (KMS) as all of the user modesetting (UMS) support has 2473 been removed from the driver. 2474 2475 Release 2.9.0 (2009-09-28) 2476 ========================== 2477 We are pleased to announce the 2.9.0 release of the xf86-video-intel 2478 driver. (If you have been following along at home, this release is 2479 identical to the 2.8.99.902 release candidate other than the version 2480 number). 2481 2482 New features in 2.9 compared to 2.8 2483 ----------------------------------- 2484 * Support for the B43 chipset. 2485 2486 Major fixes in 2.9.0 compared to 2.8.0 2487 -------------------------------------- 2488 * Multiple fixes to make the driver stable for 8xx chipsets, (855GM, 2489 865G, etc.). The 2.8 driver series was extremely unstable with many 2490 of these chipsets. 2491 2492 https://bugs.freedesktop.org/show_bug.cgi?id=22904 (and many duplicates) 2493 https://bugs.freedesktop.org/show_bug.cgi?id=22947 2494 2495 * Add support for BACKLIGHT property when using kernel modesetting 2496 (KMS). This allows backlight adjustment with programs such as 2497 "xbacklight -set <percentage>" or "xrandr --set BACKLIGHT <value>". 2498 2499 https://bugs.freedesktop.org/show_bug.cgi?id=20963 2500 2501 * Fix so that "xrandr --scale" works when using KMS. 2502 2503 https://bugs.freedesktop.org/show_bug.cgi?id=22893 2504 2505 * Fix segfaults of X server when logging out. 2506 2507 https://bugs.freedesktop.org/show_bug.cgi?id=20516 2508 2509 * Avoid falling back to software for 1-bit alpha-only masks. 2510 2511 https://bugs.freedesktop.org/show_bug.cgi?id=23184 2512 2513 * Fix pixel sampling position for 8xx chipsets, (fixes some cairo-test 2514 suite failures). 2515 2516 Snapshot 2.8.99.901 (2009-09-09) 2517 ================================ 2518 This is the first release candidate in preparation for the upcoming 2519 2.9.0 release. We will appreciate any feedback we can get from testing 2520 of this snapshot to improve the 2.9.0 release. 2521 2522 See the commit log for changes in this release, and developers, please 2523 provide me summaries for any major features in this release that you 2524 think should appear in NEWS and in the 2.9.0 release notes. 2525 2526 Note: We are still investigating failures with 865G chipsets, (these 2527 failures existed in the 2.8 series as well). We are hoping to fix 2528 these failures before the 2.9.0 release. 2529 2530 Release 2.8.0 (2009-07-20) 2531 ========================== 2532 We are pleased to present this major release of the xf86-video-intel 2533 driver. This release is very similar to the 2.7.99.902 release 2534 candidate but includes a couple of additional bug fixes, (for bugs 2535 #22760 and @22483). 2536 2537 Compared to the 2.7 releases this driver contains several new features 2538 and many bug fixes. The driver now depends on X server 1.6 or later, 2539 and eliminates several obsolete code paths, (XAA and EXA removed in 2540 favor of UXA, DRI1 support eliminated). The driver certainly will work 2541 best with an i915 module from a recent kernel (2.6.31) and with 2542 kernel-modesetting (KMS, specified by loading i915 with the option 2543 "modeset=1"). 2544 2545 New features in 2.8.0 compared to 2.7 2546 ------------------------------------- 2547 * Remove XAA/EXA/DRI1 and NoAccel, and only support UXA/DRI2 now 2548 (requiring xserver 1.6). 2549 2550 * VLD support added into XvMC for Mpeg2, which decreases CPU usage 2551 when playing video. 2552 2553 Major fixes in 2.8.0 compared to 2.7 2554 ------------------------------------ 2555 * Fix broken front-buffer rendering 2556 https://bugs.freedesktop.org/show_bug.cgi?id=19174 2557 2558 * Fix disabling of XvMC disabled 2559 https://bugs.freedesktop.org/show_bug.cgi?id=20790 2560 2561 * Fix broken VT switch on some machines 2562 https://bugs.freedesktop.org/show_bug.cgi?id=19578 2563 2564 * Improve performance of trapezoid rendering for UXA 2565 https://bugs.freedesktop.org/show_bug.cgi?id=21376 2566 2567 * Vblank sync'd GL buffer swap (fixing video tearing under composite) 2568 https://bugs.freedesktop.org/show_bug.cgi?id=20664 2569 2570 * Fix G41 DRM support 2571 https://bugs.freedesktop.org/show_bug.cgi?id=21095 2572 2573 * Fix crash on some 8xx 2574 https://bugs.freedesktop.org/show_bug.cgi?id=18974 2575 2576 Various fixes for GPU hangs, and more... 2577 2578 Snapshot 2.7.99.902 (2009-07-13) 2579 -------------------------------- 2580 This is the first release candidate in preparation for the upcoming 2581 2.8.0 release. Most major and critical bugs should be fixed, but some 2582 minor bugs may still be present. We will appreciate any feedback we 2583 can get from testing of this snapshot to improve the 2.8.0 release. 2584 2585 Snapshot 2.7.99.901 (2009-06-10) 2586 -------------------------------- 2587 This is the first release candidate in preparation for the upcoming 2588 2.8.0 release. Most critical bugs should be fixed, but some major 2589 bugs may still be present. We will appreciate any feedback we can 2590 get from testing of this snapshot to improve the 2.8.0 release. 2591 2592 Some of the major fixes in this snapshot include: 2593 2594 * Several fixes for intermittent GPU hangs/crashes, (some of 2595 which already appeared in the 2.7.1 release) 2596 2597 * Fix to avoid X crash when viewing large images in browser 2598 2599 * Fix X server failure when running old (non-GEM) kernel 2600 2601 * Fixes for SDVO LVDS mode detection 2602 2603 * Fix major performance regression of trapezoid rendering 2604 compared to XAA/EXA 2605 2606 * New support for tear-free video when using KMS 2607 2608 * New support for tear-free DRI2 CopyRegion 2609 2610 Snapshot 2.7.99.1 (2009-04-28) 2611 ------------------------------ 2612 This is a development snapshot very early in the process toward 2613 developing 2.8. There have been some big changes to the code, and 2614 we're anxious to get feedback on these changes as early as possible. 2615 2616 Here is a summary of the biggest changes: 2617 2618 * Driver now depends on X server 1.6 or later 2619 2620 * Eliminate XAA and EXA support (in favor of UXA) 2621 2622 * Eliminate DRI1 support 2623 2624 * Fixes for running without DRI at all 2625 2626 These code removals represent a deletion of a substantial amount of 2627 code, (and hopefully piles of bugs), as well as reduce the maintenance 2628 effort going forward as the number of combinatorial configurations for 2629 the driver are greatly reduced. This means that users are much more 2630 likely to be running code that has actually been tested, and it will 2631 be much easy for developers to replicate bugs that users experience. 2632 2633 One of the things that would be most useful in testing this release is 2634 to revisit any outstanding bugs that you have previously reported. If 2635 the buggy behavior is gone, (or the bug is no longer relevant---such 2636 as a bug that's specific to XAA only), please feel free to indicate so 2637 in bugzilla or even just close the bug. 2638 2639 If you confirm that the bug is still present, please indicate so in 2640 the bug report. (I was going to ask that you select a 1.7.99 version, 2641 but it looks like bugzilla only has versions for products not 2642 compoenents, while we use a "xorg" product and a "driver/intel" 2643 component.) We definitely want to make any such confirmed bugs a 2644 priority, so it would be nice to have a consistent mechanism to search 2645 for these bugs. Suggestions are welcome on the best approach. 2646 2647 Thanks in advance for any testing or feedback on this snapshot. 2648 2649 Release 2.7.0 (2009-04-15) 2650 -------------------------- 2651 Compared to the 2.6 series, 2.7.0 has a large number of bug fixes, but 2652 also a few significant features, such as: 2653 2654 SDVO-TV support, available on ADD2 card (bug#9992) and 2655 D945GCLF2 board (bug#17776). 2656 2657 Basic SDVO-LVDS support 2658 2659 XV video display without tearing 2660 [Though this isn't working for all users yet, see 2661 https://bugs.freedesktop.org/show_bug.cgi?id=21076 ] 2662 2663 Various fixes for UXA, DRI2, and Kernel modesetting. 2664 2665 We encourage users to use kernel modesetting and UXA acceleration with 2666 this release, which should give the best performance and 2667 robustness. When KMS is available, UXA is the default acceleration 2668 used by the driver, (EXA is the default otherwise). 2669 2670 Known issue: 2671 2672 Some Linux kernel versions (such as 2.6.29) are known to have 2673 broken PAT code that causes recent versions of this driver to 2674 fail, (which can manifest as the X server simply not 2675 starting). This can be verified by adding the "nopat" option 2676 to the kernel command-line and seeing the failure go away. We 2677 hope that newer kernels in the 2.6.29.x as well as 2.6.30 and 2678 above will have working PAT code. 2679 2680 Some of the most notable bugs fixed in 2.7.0 include: 2681 2682 [GM45 965GM] bad htotal causes panel startup failure 2683 https://bugs.freedesktop.org/show_bug.cgi?id=17292 2684 2685 [xrandr TV] need TV output property control 2686 https://bugs.freedesktop.org/show_bug.cgi?id=12763 2687 2688 [TV] "xrandr --set TV_FORMAT" gets BadMatch error 2689 https://bugs.freedesktop.org/show_bug.cgi?id=16566 2690 2691 [945 tiling] Low performance due to no A17 workaround 2692 https://bugs.freedesktop.org/show_bug.cgi?id=16835 2693 2694 [TV]Flicker when launching applications in the 2.4-branch 2695 https://bugs.freedesktop.org/show_bug.cgi?id=17405 2696 2697 [945GM FBC] FBC causes underruns & flicker 2698 https://bugs.freedesktop.org/show_bug.cgi?id=18651 2699 2700 [xv] Textured video suffers from tearing 2701 https://bugs.freedesktop.org/show_bug.cgi?id=19635 2702 2703 [G45] Random hangs with UXA 2704 https://bugs.freedesktop.org/show_bug.cgi?id=19734 2705 2706 [945GM] Any 3D app is slow in resolution higher than 800x600 2707 with UXA+DRI2, due to tiling 2708 https://bugs.freedesktop.org/show_bug.cgi?id=19738 2709 2710 [i915 UXA,EXA] rotation messes display with tiling on 2711 https://bugs.freedesktop.org/show_bug.cgi?id=20265 2712 2713 [G45] DRI2/UXA gives solid white instead of transparency 2714 https://bugs.freedesktop.org/show_bug.cgi?id=20321 2715 2716 LVDS output not detected 2717 https://bugs.freedesktop.org/show_bug.cgi?id=20517 2718 2719 xf86-video-intel-2.6.3: Xv crashes X server 2720 https://bugs.freedesktop.org/show_bug.cgi?id=20525 2721 2722 [G965 non-GEM] systray in KDE 4 completely broken 2723 https://bugs.freedesktop.org/show_bug.cgi?id=20527 2724 2725 [SDVO-TV]the desktop is teared in four sections on the screen 2726 https://bugs.freedesktop.org/show_bug.cgi?id=20550 2727 2728 Intel video driver 2.6.3 crashes with XVideo 2729 https://bugs.freedesktop.org/show_bug.cgi?id=20563 2730 2731 [855GM] Xv crash with non-KMS 2732 https://bugs.freedesktop.org/show_bug.cgi?id=20585 2733 2734 2.6.99.902 breaks native 1680x1050 mode on TMDS -- EDID miss 2735 https://bugs.freedesktop.org/show_bug.cgi?id=20594 2736 2737 [945GM TV] 2.6.99.902 sets a too high CONTRAST-value 2738 https://bugs.freedesktop.org/show_bug.cgi?id=20670 2739 2740 [915GM] fail to detect LVDS with new VBT code 2741 https://bugs.freedesktop.org/show_bug.cgi?id=20752 2742 2743 [regression i965]tiled output when start X 2744 https://bugs.freedesktop.org/show_bug.cgi?id=20803 2745 2746 2.6.99.902: LVDS wrongly detected as disconnected 2747 https://bugs.freedesktop.org/show_bug.cgi?id=20826 2748 2749 vt switching fails and crashes X 2750 https://bugs.freedesktop.org/show_bug.cgi?id=20863 2751 2752 [HDMI] The screen will flicker when some application runs on 2753 G45-64 2754 https://bugs.freedesktop.org/show_bug.cgi?id=20875 2755 2756 TexturedVideo is offsetted wrongly on dualhead 2757 https://bugs.freedesktop.org/show_bug.cgi?id=20980 2758 2759 [EXA] xvideo hang X 2760 https://bugs.freedesktop.org/show_bug.cgi?id=21027 2761 2762 [EXA] x11perf performance regression 2763 https://bugs.freedesktop.org/show_bug.cgi?id=21029 2764 2765 And many others... 2766
