NEWS revision 1.1.1.3
1 Snapshot 2.99.916 (2014-09-08) 2 ============================== 3 Quick update for MST in UXA - we need to hook up the RandR outputs for 4 dynamicaly added connectors. 5 6 7 Snapshot 2.99.915 (2014-09-08) 8 ============================== 9 A significant change to UXA to enable MST and to keep it working on recent 10 kernels needs some soaking before a major release, and the usual 11 plethora of bugfixes. One other feature is the support for hardware 12 rotations on very recent kernels. 13 14 * Handle rotated scanouts that are all clear correctly. The region to 15 update was not being computed correctly, overdrawing the wrong CRTC. 16 https://bugs.freedesktop.org/show_bug.cgi?id=81820 17 18 * Reset cursor images after rotation and size changes 19 https://bugs.freedesktop.org/show_bug.cgi?id=81886 20 https://bugs.freedesktop.org/show_bug.cgi?id=82273 21 https://bugs.freedesktop.org/show_bug.cgi?id=82337 22 23 * Handle stale DRI2 buffers and Client errors more gracefully 24 25 * Fallback if we fail to render a glyph onto a too-large surface, e.g. 26 direct rendering of glyphs onto extended desktops with gen2/gen3. 27 https://bugs.archlinux.org/task/40949 28 29 * Further work to enable tiled rendering onto large surfaces in 30 severely aperture and memory constrained devices (e.g. gen2/gen3) 31 32 * Honour the Primary option from xorg.conf and mark that as the RandR 33 primary. 34 https://bugs.freedesktop.org/show_bug.cgi?id=82193 35 https://bugs.freedesktop.org/show_bug.cgi?id=82205 36 37 * Fix another Client-Window DRI2 close race 38 https://bugs.freedesktop.org/show_bug.cgi?id=82979 39 40 * Fix incorrect discarding of GPU damage when copying over the TearFree 41 scanout - which caused a flicker in rapidly updated elements (like 42 simple video panes). 43 https://bugs.freedesktop.org/show_bug.cgi?id=81973 44 45 46 Snapshot 2.99.914 (2014-07-23) 47 ============================== 48 And a brown paper bag to hide the rebuilding from the tarball with 49 'autoreconf -fi' error that arose from not distributing the libobj/ 50 directory. 51 52 53 Snapshot 2.99.913 (2014-07-23) 54 ============================== 55 This should be it... A few fixes from testing the new code, we should be 56 ready for the final release. However, we do have one standout feature in 57 this snapshot, we now officially recognise HD Graphics 5300/5500/5600, 58 Iris Graphics 6100 and Iris Pro Graphics 6200/P6300 (formerly known as 59 Broadwell). 60 61 * Check the window actually covers the CRTC before doing a single CRTC flip, 62 and then restore the right framebuffer after completing CRTC flips. 63 Otherwise we would detect an error and disable an output under TearFree 64 Regression in 2.99.912 65 https://bugs.freedesktop.org/show_bug.cgi?id=80191 66 67 * Fix framebuffer creation on kernels older than 3.11 68 Regression in 2.99.912 69 70 * Check that the damage still exists after implicit reduction 71 Regression in 2.99.912 72 https://bugs.freedesktop.org/show_bug.cgi?id=77436 73 74 * Fix direction flags for fallback composited CopyAreas which 75 caused scrolling corruption in a few configurations 76 Regression from 2.20.0 77 https://bugs.freedesktop.org/show_bug.cgi?id=79843 78 79 * Do not throw away damage if there is no redundant copy 80 https://bugs.freedesktop.org/show_bug.cgi?id=79992 81 82 * Check clipping on PolyRect before discarding the clipped damage 83 Regression from 2.99.903 84 https://bugs.freedesktop.org/show_bug.cgi?id=79992 85 86 * Fix hints for GLXPixmapa, as these are never swapped and so 87 miss invalidating the hints on SwapBuffers with the result 88 that they are often presumed blank 89 Regression in 2.99.912 90 https://bugs.freedesktop.org/show_bug.cgi?id=79999 91 92 * Fix incoherent choice of source bo when constructing 8x8 tiles, 93 incorrect pattern origin when extracting, and then fix the 94 alignment of colour patterns for BLT operations 95 https://bugs.freedesktop.org/show_bug.cgi?id=80033 96 97 * Disable blending with the render engine on snoopable buffers 98 https://bugs.freedesktop.org/show_bug.cgi?id=80253 99 100 * Restore throttling to prevent client lag under heavy GPU load 101 Regression from 2.21.10 102 https://bugs.freedesktop.org/show_bug.cgi?id=77436 103 104 * Use ClientGone for notifications on shared DRI2 windows to prevent 105 rare crashes due to use-after-free of the swap requests 106 https://bugs.freedesktop.org/show_bug.cgi?id=80157 107 108 * Ensure the mmaped CPU bo is idle before migrating damage 109 https://bugs.freedesktop.org/show_bug.cgi?id=80560 110 111 * Fix incorrect clipping by the render engine for large DRI2 windows 112 113 * Ensure that the aperture tiling fallbacks are bounded 114 115 * Validate parameter to xf86-video-intel-backlight-helper more carefully 116 (CVE-2014-4910) 117 118 * Fix slaved scanouts for reverse optimus, though rotated slaves will 119 require further patches to Xorg. 120 https://bugs.freedesktop.org/show_bug.cgi?id=81383 121 122 * Fix build without Composite extension. 123 124 * Fix build without gettline(). 125 126 * UXA: Allocate and resize frontbuffer consistently to pass sanity checks 127 https://bugs.freedesktop.org/show_bug.cgi?id=80088 128 129 * UXA: Report cached backlight value when the output is off (like sna) 130 https://bugzilla.redhat.com/show_bug.cgi?id=1032978 131 132 * UXA: Mark outputs as off before the kernel does (like sna) 133 This will prevent the internal panel from starting up blank in some 134 multi-monitor configurations 135 https://bugzilla.redhat.com/show_bug.cgi?id=1103806 136 137 Note that the DRI2 exchange mechanism introduced in 2.99.912 exposes bugs 138 in some compositors, at least kwin and comptom, which discard DRI2 buffer 139 invalidates rather than resourcing their texture. For example, 140 https://bugs.kde.org/show_bug.cgi?id=336589 141 142 Note that the improved triple buffering introduced in DRI2 requires a patch 143 to Xorg (now released upstream) to prevent crashes with DRI_PRIME. 144 https://bugs.freedesktop.org/show_bug.cgi?id=80001 145 146 Note that DRI3/Present require tracking the relevant development trees for 147 mesa and the xserver as they are very much still under early testing. Also 148 be aware that Mesa provides no support for explicit fencing so Damage 149 tracking between compositors and clients is unserialised. 150 151 152 Snapshot 2.99.912 (2014-06-10) 153 ============================== 154 A final round of features. We have everything from support for variable 155 cursor sizes, support for the DRI3 and Present extensions, improved DRI2 156 support, support for Xserver 1.16, userptr from kernel 3.16, and 157 precursory support for DP multistream transport, 158 159 * Avoid discarding dirty pixels when promoting a migration to cover the 160 whole pixmap. 161 Regression in 2.99.911 162 https://bugs.freedesktop.org/show_bug.cgi?id=77063 163 https://bugs.freedesktop.org/show_bug.cgi?id=77178 164 165 * Avoid overextending degenerate lines (and consequentially accessing 166 pixels outside of our damaged area). 167 https://bugs.freedesktop.org/show_bug.cgi?id=77074 168 169 * Fix subpixel glyph rendering on gen2 devices (830-865 chipsets) 170 Regression in 2.99.911 171 https://bugs.freedesktop.org/show_bug.cgi?id=77201 172 173 * Share the global pixman glyph cache between ZaphodHeads 174 https://bugs.freedesktop.org/show_bug.cgi?id=54707 175 176 * Light up all connected outputs, even if their status is unknown, on 177 takeover from fbcon. This prevents loss of display after a resume 178 on recent kernels, for example. 179 https://bugs.freedesktop.org/show_bug.cgi?id=77768 180 181 * Show the video overlay (when supported by the hardware) across all 182 outputs. 183 https://bugs.freedesktop.org/show_bug.cgi?id=77802 184 185 * Do not discard damage when performing "BLT" spans inplace with the CPU. 186 Regression from 2.20.10 187 188 * Avoid discarding IO buffers too early during their preparation for a 189 new batch 190 https://bugs.freedesktop.org/show_bug.cgi?id=79238 191 192 * Fix fallback handling for displaying large scaled framebuffers (that 193 are too large to be scaled by the GPU in a single pass) 194 https://bugs.freedesktop.org/show_bug.cgi?id=79320 195 196 * Listen to external modifications of backlight value and propagate 197 the notifications to RandR clients. This should make the GUI report 198 ACPI keypresses to change the backlight correctly. 199 https://bugs.freedesktop.org/show_bug.cgi?id=79699 200 201 * UXA: fix pageflips with 3 heads. 202 203 * UXA: do not report a BadMatch error for DRI2GetMsc - as clients are 204 often unprepared and die when they get the unexpected error. 205 206 207 Snapshot 2.99.911 (2014-03-19) 208 ============================== 209 Hans de Geode has been working on making the Xserver work without 210 privileges under the supervision of systemd/logind. This necessitated a 211 few new features for us: server fds (where we are passed which fd to use 212 to talk to our device by the Xserver who may in turn receive it from 213 logind or other host) and a small backlight helper so that we can continue 214 to provide a RandR backlight property when running without root privileges. 215 216 * Flush when changing blend modes on Ironlake, or else single glyphs 217 are sometimes rendered incorrectly 218 Regression from 2.20.15 219 https://bugs.freedesktop.org/show_bug.cgi?id=74882 220 221 * Fix pixmap offsets for pixman fallbacks onto Composite redirected 222 windows 223 https://bugs.freedesktop.org/show_bug.cgi?id=73811 224 225 * Fix blending onto 8-bit destinations, typically used for generating 226 masks in complex Render operations, on gen2 227 https://bugs.freedesktop.org/show_bug.cgi?id=75818 228 229 * Handle failure to create DRI bo more carefully. For example on gen3, 230 the DDX supports pixmaps that are much, much larger than OpenGL can 231 use and do not support the tiling modes that we request for OpenGL. 232 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1289049 233 234 * Fix a bookkeeping bug with proxy buffers that are marked active but 235 not actually inserted into a request (so they end up permanently 236 active and confuse everybody). 237 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1289923 238 239 * Actually turn off displays with DPMS off for UXA. 240 Regression from 2.99.903, but requires 241 242 kernel commit c9976dcf55c8aaa7037427b239f15e5acfc01a3a 243 Author: Chris Wilson <chris (a] chris-wilson.co.uk> 244 Date: Sun Sep 29 19:15:07 2013 +0100 245 246 drm/i915: Only apply DPMS to the encoder if enabled 247 248 instead for correct behaviour on Haswell. 249 https://code.google.com/p/chromium/issues/detail?id=341135 250 251 252 Snapshot 2.99.910 (2014-02-10) 253 ============================== 254 Another latent bug exposed by recent changes merit another snapshot for 255 final testing. 256 257 * Only discard damage when overwriting the dirty CPU bo, instead 258 of discarding damage that will be shown! 259 260 * Reset operation state when switching between glyph caches. 261 https://bugs.freedesktop.org/show_bug.cgi?id=74494 262 263 * Fully reinitialise pixmaps allocated from the freed cache. Fixes 264 a potential issue (crash or misrendering) when using some compositors. 265 https://bugs.freedesktop.org/show_bug.cgi?id=74550 266 267 * Do not expose the TexturedVideo adaptor in UXA when it is disabled 268 either due to a hung GPU or explicitly disabled by the user. 269 270 * Restore the pipe stall when changing CC state on gen6, otherwise 271 the GPU may not flush intermediate results from all EU resulting 272 in render corruption (usually the occasional black box). 273 Regression from 2.99.906 274 https://bugs.freedesktop.org/show_bug.cgi?id=7237 275 276 277 Snapshot 2.99.909 (2014-02-01) 278 ============================== 279 Pass the brown paper bag. Ridiculously stupid bug in last minute coding. 280 281 * Add Xv support using glamor acceleration in addition to adaptors 282 provided by the UXA backend. 283 284 * Fix overeager discarding of CPU damage 285 Regression in 2.99.908 :( 286 https://bugs.freedesktop.org/show_bug.cgi?id=74327 287 288 289 Snapshot 2.99.908 (2014-01-31) 290 ============================== 291 A couple of regressions dashed the hopes that .907 was to be the final 292 release candidate, so time to start the cycle again after applying a few 293 more bugfixes. 294 295 * Fix invalid pageflipping of GLXPixmaps by UXA. 296 https://bugs.freedesktop.org/show_bug.cgi?id=73282 297 298 * Consistently treat DPMS Suspend/Standy as Off, otherwise we may 299 incorrectly restore the backlight in UXA. 300 301 * Fix disabling the backlight in UXA when querying the value whilst off 302 https://bugs.freedesktop.org/show_bug.cgi?id=73181. 303 304 * Invalidate between every operation if rendering into the source or mask. 305 Fixes regression in 2.99.907 on Ivybridge (seen in KDE) 306 https://bugs.freedesktop.org/show_bug.cgi?id=73208 307 308 * Check for available batch buffer state before restoring state on gen4, 309 otherwise we overwrite surface state with commands and cause a GPU hang. 310 https://bugs.freedesktop.org/show_bug.cgi?id=73348 311 312 * Prevent an invalid free by TearFree 313 https://bugs.freedesktop.org/show_bug.cgi?id=73469 314 315 * Fix confusion in TearFree when it tried to pageflip to a stale bo 316 https://bugs.freedesktop.org/show_bug.cgi?id=70905 317 318 * Initialise TearFree contents with the current frontbuffer upon creation, 319 otherwise old content may be visible for significant fractions of a 320 second after resume or DPMS on 321 https://bugs.freedesktop.org/show_bug.cgi?id=73842 322 323 * Nullify the old pointer into a CPU mmapping of the bo when promoting it 324 on the GPU. Eventually that old pointer becomes invalid and will cause 325 the Xserver to crash. 326 Fixes regression in 2.99.906 327 https://bugs.freedesktop.org/show_bug.cgi?id=73351 328 329 * Restore the serialNumber on the GC correctly after falling back to 330 software. This was seen to cause corruption with Wine. 331 https://bugs.freedesktop.org/show_bug.cgi?id=73856 332 333 * Do not ignore CPU damage on a pixmap unless the Composite operation 334 will completely overwrite it. This was observed in xfce4. 335 https://bugs.freedesktop.org/show_bug.cgi?id=69528 336 337 * Skip fake outputs during initial probe as they can cause a NULL pointer 338 dereference. 339 https://bugs.freedesktop.org/show_bug.cgi?id=73981 340 341 * Fix rendering of dashed zero-width lines onto 24bit buffers 342 https://bugzilla.redhat.com/show_bug.cgi?id=1059152 343 344 * Cap the freed Pixmap cache and reuse it more often 345 Fixes a regression in 2.99.907 that caused the memory used by X to 346 grow until it was cleaned up during server regreneration 347 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1272338 348 349 350 Snapshot 2.99.907 (2013-12-30) 351 ============================== 352 The highlight here is that things seem to be quietening down on the bug 353 reporting front. All is not quiet as you will see below, and maybe it is 354 just the holiday season that is approaching*, but there has been a 355 remarkable falloff in bug reports. Lets hope this trend holds and we can 356 make a stable release shortly! 357 358 * This was intended to be sent a couple of weeks ago and the holiday season 359 has been very quiet.... 360 361 Oh, and acceleration support for Intel's next generation of 362 integrated processor graphics has landed, codenamed Broadwell. 363 364 * Fix potential X server infinite recursion (crash) from a gen2 bug fix 365 Regression in 2.99.906 366 https://bugs.freedesktop.org/show_bug.cgi?id=71605 367 368 * Workaround a missing pipeline flush within Ivybridge, that would 369 leave black rectangles randomly over the output 370 https://bugs.freedesktop.org/show_bug.cgi?id=68410 371 372 * Fix tiled fills. gen2-3 and gen4+ had two different bugs that 373 both broke rendering with small 8x8 patterns in some circumstances 374 https://bugs.freedesktop.org/show_bug.cgi?id=71260 375 376 * Fix reads from a cropped video image using a packed pixel format. 377 378 * Another clear the clear hint after DRI2 SwapBuffers, like the bug fixed 379 in 2.99.903. Failure to clear the hint would cause read backs of the 380 frontbuffer (Xvnc) to be blank. 381 https://bugs.freedesktop.org/show_bug.cgi?id=72194 382 383 * Disable VSync on Baytrail 384 https://bugs.freedesktop.org/show_bug.cgi?id=69869 385 386 * Handle partial uploads with TearFree correctly 387 https://bugs.freedesktop.org/show_bug.cgi?id=72343 388 https://bugs.freedesktop.org/show_bug.cgi?id=72430 389 390 * Avoid recusing through DRI event handlers whilst processing TearFree, 391 leading to a double free (and memory corruption) 392 https://bugs.freedesktop.org/show_bug.cgi?id=72690 393 394 * Hide the gen4 render corruption by crippling the GPU 395 https://bugs.freedesktop.org/show_bug.cgi?id=55500 396 397 398 Snapshot 2.99.906 (2013-11-13) 399 ============================== 400 Several stability fixes required after the recent tweaking of the core 401 mechanics to handle the updated TearFree and attempting to make static 402 analyzers happy. 403 404 * Fix damage handling when rendering to a partially damaged GPU surface. 405 Regression in 2.99.905 406 https://bugs.freedesktop.org/show_bug.cgi?id=70527 407 408 * Use asprintf() instead of sprintf() 409 Regression in 2.99.905 410 https://bugs.freedesktop.org/show_bug.cgi?id=70835 411 412 * Improve accounting for fence overallocation on older gen2/3, and 413 improve the tiling mechanism to fit into the same aperture constraints 414 https://bugs.freedesktop.org/show_bug.cgi?id=70924 415 416 * Add an extra GPU flush on Sandybridge to fix some rare font corruption 417 418 * Rasterise lines through all clip boxes 419 https://bugs.freedesktop.org/show_bug.cgi?id=70802 420 421 * Fix regression from stricter handling of failures to move a GC to the GPU 422 Regression in 2.99.905 423 https://bugs.freedesktop.org/show_bug.cgi?id=71415 424 425 * Fix various fail along the memcpy_xor paths, including inadequate error 426 handling and integer overflow 427 https://bugs.freedesktop.org/show_bug.cgi?id=70527 428 429 * Fix outside-of-target stipple uploads 430 https://bugs.launchpad.net/bugs/1247785 431 432 * Fix clip detection for long glyphs 433 Incomplete bug fix (causing a regression) in 2.99.905 434 https://bugs.freedesktop.org/show_bug.cgi?id=70527 435 436 * Fix VSync for the render engine (Xv) on Haswell 437 https://bugs.freedesktop.org/show_bug.cgi?id=70527 438 439 440 Snapshot 2.99.905 (2013-10-23) 441 ============================== 442 The highlight for this snapshot is the extension of TearFree to support 443 transformed outputs, along with some polishing to eliminate its impact 444 upon input and output latency. As always, thanks to everyone who have 445 been testing, reporting bugs and helping to improve the stability before 446 release. 447 448 * Prevent a crash when starting with a user specified mode or position 449 450 * Prevent some crashes in UXA after allocation failure 451 452 * Stop marking the user's preferred backlight value as 0 if the 453 backlight property is queried whilst the connector is disabled 454 https://bugs.freedesktop.org/show_bug.cgi?id=70406 455 456 * Pad GETCONNECTOR ioctl for compatability between 32/64-bit userspace 457 and kernel 458 459 * Handle long glyph runs correctly 460 https://bugs.freedesktop.org/show_bug.cgi?id=70541 461 462 * Fix clipping of stippled rectangles against clip regions 463 https://bugs.freedesktop.org/show_bug.cgi?id=67865 464 465 * Support TearFree rendering of rotated outputs 466 https://bugs.freedesktop.org/show_bug.cgi?id=22969 467 468 469 Snapshot 2.99.904 (2013-10-09) 470 ============================== 471 There is one more feature planned to be completed for 3.0, so time for a 472 snapshot beforehand to push out the bug fixes from the last week. 473 474 * Fix video output using sprites when changing the image size 475 476 * Apply more restrictive tile constaints for 915g class devices 477 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1232546 478 479 * Ensure all overlapping rectangles are drawn for XRenderFillRectangles 480 https://bugs.freedesktop.org/show_bug.cgi?id=66313 481 482 * Fix trapezoid clipping against the left-edge 483 https://bugs.freedesktop.org/show_bug.cgi?id=69469 484 485 * Prevent discarding active upload buffers, causing glitches in chromium 486 https://bugs.freedesktop.org/show_bug.cgi?id=66990 487 488 * Prevent specifying a negative timeout to select if the BlockHandler 489 takes too long to update the display 490 491 * Promote the Ironlake pipecontrol to be a full pipeline flush to 492 prevent render cache corruption 493 https://bugs.freedesktop.org/show_bug.cgi?id=51422 494 495 * Never pass an invalid trapezoid to pixman 496 https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1197921 497 498 * Prevent out-of-bounds access by overassigning work amongst threads 499 https://bugs.freedesktop.org/show_bug.cgi?id=70204 500 501 * Make sure the current mode is always listed amongst the output modes 502 https://bugs.freedesktop.org/show_bug.cgi?id=70132 503 504 * Build fixes for 1.14.99.2 505 506 507 Snapshot 2.99.903 (2013-09-28) 508 ============================== 509 Lots more stabilization work, not yet peaceful enough to christen 3.0. We 510 have everything ranging from build fixes for systems like Suse Linux 511 Enterprise Desktop that like to backport hardware enablement to ancient 512 packages, to fixes for hardware enabling, and some more performance tuning. 513 514 * Fix VSync on Haswell. 515 https://bugs.freedesktop.org/show_bug.cgi?id=69119 516 517 * Disable Y-tiling on gen4 - it too frequently leads to instability. 518 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1222203 519 520 * Disable same EDID detection based on property id - the kernel likes 521 to reuse ids leading to a failure to detect the right modes on a monitor 522 change. 523 524 * Avoid issuing multiple DPMS requests to the same encoder (alised to 525 multiple connectors) to avoid upsetting Haswell and leaving the 526 screens blank. 527 528 * Honour the user preferrence for the initial mode, even if they are 529 being silly 530 https://bugzilla.novell.com/show_bug.cgi?id=841696 531 532 * Clear the clear hint when apply DRI updates - to prevent some 533 screenshots from GL windows being left blank. 534 https://bugs.freedesktop.org/show_bug.cgi?id=69730 535 536 * Prevent a NULL dereference from trying to undo an non-existent buffer 537 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1228677 538 539 * Handle out-of-memory conditions far more gracefully. If the system is 540 hard against the memory wall, then the kernel will start issuing 541 SIGBUS even for CPU mmaps. Untrapped these will cause X to die. 542 https://bugs.freedesktop.org/show_bug.cgi?id=67889 543 544 545 Snapshot 2.99.902 (2013-09-07) 546 ============================== 547 We do not condone or support Canonical in the course of action they have 548 chosen, and will not carry XMir patches upstream. 549 -The Management 550 551 Snapshot 2.99.901 (2013-09-04) 552 ============================== 553 What's this? A pre-release snapshot of an upcoming 3.0 major release? 554 What could be the big new feature about to land? SNA by default! 555 Not only that, we also have a preview of the XMir integration patches. 556 557 Whilst we consider the SNA acceleration method to be ready to take over 558 from UXA (the current acceleration method), it still remains possible to 559 switch over to the old method with the following xorg.conf snippet: 560 Section "Device" 561 Identifier "Device0" 562 Driver "intel" 563 Option "AccelMethod" "UXA" 564 EndSection 565 566 The promise of SNA is that it improves the user experience by providing a 567 faster, more fluid, desktop, that is both more power efficient and less 568 prone to crashes than UXA. If it still fails to meet your expections, 569 please file bugs! 570 571 572 Release 2.21.15 (2013-08-21) 573 ============================ 574 Some build fixes for the BSDs and alternate compiler, and conflicting 575 configure options and a critcial fix for some PRIME setups. 576 577 * Don't fail to configure if DRI1 is not available and the user asks 578 for both DRI and KMS-only 579 [Regression from 2.21.14] 580 581 * Lots of miscellaneous fixes for older gcc, other compilers and BSD. 582 583 * Initial framework support for hosted X. 584 585 * Improve transition from fbcon to X with multiple outputs and extended 586 desktops. 587 588 * Ensure the framebuffer exists before checking it against the CRTC 589 constraints. 590 https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/121234 591 [Regression from 2.21.10] 592 593 * Add RGB overlay support for Ironlake and later. 594 595 * Don't release the overlay buffer too early, i.e. before the client 596 disables the Xv image. 597 598 * Tweak the ring switching logic to reduce use of semaphores on 599 Sandybridge and later - a delicate balancing act between trying to 600 use the faster engine for the task and preventing concurrent use of 601 multiple rings. 602 603 604 Release 2.21.14 (2013-08-04) 605 ============================ 606 A few updates for the top-end Haswell systems (notably GT3 and GT3e 607 systems), in particular, setting the appropriate thread counts for the 608 larger GPU and handling a few scaling issues with the emedded DRAM. More 609 important than the performance tuning though is a fix for a critical 610 issue encountered by a few people on gen4/gen5 systems. 611 612 * Initial performance tuning for HSW:GT3e 613 614 * Fix a crash with Planetary Annihilation 615 616 * Disable triple buffering for compositors 617 618 * Reserve space in the exec buffer array for deferred VBOs. 619 https://bugs.freedesktop.org/show_bug.cgi?id=67504 620 621 622 Release 2.21.13 (2013-07-27) 623 ============================ 624 A minor release to repair the build for non-Linux systems, and to undo a 625 few more regressions. 626 627 * Avoid potential memory corruption with allocations of very small 628 depth 1 bitmaps. 629 630 * Fix source clipping whilst computing copy extents and exposures. 631 [Regression from 2.21.12] 632 https://bugs.freedesktop.org/show_bug.cgi?id=66970 633 634 * Use /proc/cpuinfo if cpuid4 is not available (old hardware or old 635 gcc), and repair the build on systems without cpuid. 636 [Regression from 2.21.12] 637 638 * Fix performance regression on Ironlake from inadvertently flushing 639 after every operation. 640 [Regression from 2.21.11] 641 https://bugs.freedesktop.org/show_bug.cgi?id=67157 642 643 * Fix conflict handling when probing initial KMS configuration for 644 ZaphodHeads. 645 [Regression from 2.21.11] 646 https://bugs.freedesktop.org/show_bug.cgi?id=67176 647 648 * Stop being overly restrictive and rejecting stale DRI2 buffers. 649 (DRI2 is inherently racy in that the client may have completed and 650 submitted rendering to buffers that are now invalid on the server. 651 This race is magnified by bugs within the Xserver where it forgets 652 to notify the DRI2 clients of certain invalidation events.) 653 https://bugs.freedesktop.org/show_bug.cgi?id=67210 654 655 * Handle a failure to use a GTT mmap for a pixmap upload and try 656 an alternative method before giving up. 657 658 659 Release 2.21.12 (2013-07-14) 660 ============================ 661 In this release, we clear up the teething troubles from preserving the KMS 662 configuration, notably external connections on Haswell and plugging in new 663 outputs after startup were broken. Besides these regression fixes, there 664 are a couple of fixes for some long standing issues, such as incorrect 665 rendering on gen2, an infinite loop with very, very large pixmaps and a 666 slight improvement to the tempermental gen4. 667 668 * Allow untiled scanouts again (required for large extended desktops on 669 gen2 and gen3). 670 [Regression from 2.21.11] 671 672 * Use the correct count of the number of dirty damage boxes for the quick 673 check on whether the existing damage contains the requested area. 674 The danger is that we may get a false result and skip migration and so 675 cause pixmap corruption (in the unlikely event that the application 676 frequently causes fallbacks). 677 [Regression from 2.21.11] 678 https://bugs.freedesktop.org/show_bug.cgi?id=66430 679 680 * Fix initial connection probing for multi-function encoders, such as the 681 external connections on Haswell. 682 [Regression from 2.21.11, initial connection probing] 683 https://bugs.freedesktop.org/show_bug.cgi?id=66488 684 685 * Fix gen2 rendercopy into a8 surfaces, for example, glyph uploads into 686 the glyph cache. 687 688 * Fix detection of user overrides for initial connection configuration. 689 The code used the xorg-server-1.15 values, having missed the 690 introduction of ZoomModes into that release. 691 [Regression from 2.21.11, initial connection probing] 692 693 * Always initialise the gamma ramp, even on unconnected CRTCs. 694 https://bugs.freedesktop.org/show_bug.cgi?id=66563 695 [Regression from 2.21.11, initial connection probing] 696 697 * Some more tuning of the gen4 vertex corruption workaround. The root 698 cause behind the GPU using incorrect texture coordinates is still 699 not solved, but by reducing the maximum number or rectangles in 700 flight through the GPU we reduce the likelihood of corruption. 701 702 * Fix compilation with gcc-4.5 703 [Regression from 2.21.11] 704 705 * Avoid integer overflow when performing tiled uploads and operations 706 on very large (>28k pixels wide or tall pixmaps) 707 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1200766 708 709 710 Release 2.21.11 (2013-06-30) 711 ============================ 712 An eventful week. What started with a regression with some builds of 713 firefox on some machines lead ultimately to the discovery of an older 714 kernel bug. Aside from the work to fix the image bug and a few other 715 older bugs that were reported and resolved this week, there is also a 716 (hopefully) subtle change to the initial configuration of displays. In 717 the absence of user overrides in xorg.conf, the DDX will try to preserve 718 the same display configuration as used by the kernel, which hopefully 719 will be the same configuration as setup by the BIOS. The result should 720 be a boot sequence that does not resize at all (aka fastboot) - until 721 the display manager takes over and loads a completely different 722 configuration! 723 724 * Add reference counting of drmMaster for ZaphodHeads 725 https://bugs.freedesktop.org/show_bug.cgi?id=66041 726 727 * Add a GPU flush before changing blend modes on Ironlake 728 https://bugs.freedesktop.org/show_bug.cgi?id=51422 729 730 * Fix occasional missing images for inplace uploads 731 [regression from 2.21.10] 732 https://bugs.freedesktop.org/show_bug.cgi?id=66059 733 734 * Add missing utility files to the tarball and remove a few unused ones 735 736 * Initialise PolyPoint operand state before calling miWideDash 737 https://bugs.freedesktop.org/show_bug.cgi?id=66104 738 739 * Fix redirection handling for rendering into large surfaces 740 https://bugs.freedesktop.org/show_bug.cgi?id=66168 741 https://bugs.freedesktop.org/show_bug.cgi?id=66249 742 743 * Fix compilation of UXA with xorg-xserver < 1.10 744 [regression from 2.20.0] 745 746 * Fix consideration of gradients for deciding when to migrate render 747 operations 748 [performance regression from 2.21.10, the bug itself is older] 749 https://bugs.freedesktop.org/show_bug.cgi?id=66297 750 751 Also fixed this week was: 752 753 commit 22fd5ca947b58901927d100d2b1aa0f1672b3435 754 Author: Chris Wilson <chris (a] chris-wilson.co.uk> 755 Date: Fri Jun 28 16:54:08 2013 +0100 756 757 drm/i915: Only clear write-domains after a successful wait-seqno 758 759 which affects kernels 3.7 - 3.10, coming to a stable kernel near you soon. 760 761 762 Release 2.21.10 (2013-06-22) 763 ============================ 764 Fixes missing support for Xv (with the textured video adaptor) on 765 Haswell, and an old bug with wide monitors on various generation. Along 766 with a few other regression fixes and performance tweaks for various 767 corner cases. 768 769 * Do not lose track of fast pageflips across mode changes 770 [regression from 2.20.8] 771 772 * Fix listing of Visuals for Xv 773 [regression from 2.21.8] 774 https://bugs.freedesktop.org/show_bug.cgi?id=65479 775 776 * Improve coherency of concurrent CPU accesses to a pixmap 777 https://bugs.freedesktop.org/show_bug.cgi?id=61628 778 779 * Set sampler swizzling for textured video on Haswell 780 https://bugs.freedesktop.org/show_bug.cgi?id=65699 781 782 * Apply scanout stride limits 783 https://bugs.freedesktop.org/show_bug.cgi?id=65099 784 785 * Undo the self-copy for cloned pixmaps for loimpress's animations 786 [regression from 2.21.7] 787 https://bugs.freedesktop.org/show_bug.cgi?id=65665 788 789 790 Release 2.21.9 (2013-06-06) 791 =========================== 792 Consolidating the copy-on-write support, hopefully cleaning up the last of 793 the regressions. 794 795 * Restore vsync on textured videos. 796 [regression from 2.21.8] 797 https://bugs.freedesktop.org/show_bug.cgi?id=65048 798 799 * Fix incorrect ordering of possible_clones with certain outputs, which 800 can lead to attempting to incorrectly clone 2 outputs and failing to 801 light them up. 802 [regression from 2.20.10] 803 804 * Fix performance regression from not promoting large fills to the GPU 805 [regression from 2.21.7] 806 807 * Undo the pixmap clone before performing a DRI2CopyRegion 808 [regression from 2.21.7] 809 https://bugs.freedesktop.org/show_bug.cgi?id=65250 810 811 812 Release 2.21.8 (2013-05-27) 813 =========================== 814 A quick release to cleanup a few regressions from the introduction of 815 copy-on-write support, notably hitting wine applications and a memory 816 leak for firefox. 817 818 * Only mark a PolyFillRect operation as replacing if it is unclipped 819 https://bugs.freedesktop.org/show_bug.cgi?id=64841 820 821 * Prevent potential NULL dereference of damage when checking COW support 822 823 * Fix invalidation of clone after dirtying the pixmap via the CPU 824 825 * Prevent discarding an operation before requiring it for a fallback 826 827 * Fix memory leak from replacing the clone under certain circumstances 828 https://bugs.freedesktop.org/show_bug.cgi?id=64978 829 830 831 Release 2.21.7 (2013-05-21) 832 =========================== 833 A couple of weeks turned into a month and a couple of weeks... Amidst 834 the usual bug fixes, we have added the complete set of Haswell PCI IDs - 835 hopefully future proofing ourselves against being surprised by new 836 products. We can also now use the correct term for the top of the range 837 Haswell variants, GT3. 838 839 * Fix several assertion failures hit by Jiri Slaby. 840 841 * Allow XvMC to also target overlay/sprite planes. 842 843 * Throw in a paranoid MI_FLUSH between BLT and RENDER operations on 844 Ironlake. 845 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1168066 846 847 * Prevent reuse of old framebuffers after a resize. 848 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1157678 849 850 * Fix compilation with --enable-valgrind and no --enable-debug 851 852 * Improve partial migration of render sources. 853 854 * Fix origin of trapezoids. 855 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1178020 856 857 * Introduce copy-on-write support for cloning pixmaps. The ultimate 858 goal here is to efficiently support the TearFree mode of operation, 859 but this provides immediate benefits with firefox - most importantly 860 because of the inefficient way it now implements scrolling. 861 862 863 Release 2.21.6 (2013-04-06) 864 =========================== 865 A surprising highlight of this release is a little refresh to the KMS 866 support for OpenBSD. OpenBSD now has its own KMS implementation which is 867 mostly compatible with the interface in Linux, with one or two tweaks 868 supplied by Mark Kettenis. This release continues to cleanup behaviour 869 for Haswell. 870 871 * Workaround a failure by the xserver to invalidate DRI buffers 872 following a pixmap change for XComposite redirection. 873 https://bugs.freedesktop.org/show_bug.cgi?id=62614 874 875 * Fix computation of clip extents for stippling 876 https://bugs.freedesktop.org/show_bug.cgi?id=62618 877 878 * Support KMS on OpenBSD, by Mark Kettenis 879 880 * Clean up sockets upon CloseScreen (making ourselves better behaved 881 for muxed setups). 882 883 * Fix the tests for AVX/AVX2 support in CPUID and remember to check for 884 OS support as well. 885 886 * Report a monotonic UST value for undisplayed drawables rather than 0 887 by Daniel Kurtz 888 889 * Fix video playback on gen4 through a complex clip (more gen4 GPU woes) 890 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1162046 891 892 893 Release 2.21.5 (2013-03-21) 894 =========================== 895 Haswell reintroduces a command to load the scanline window from the 896 command stream and so requires its own specialised wait-for-vsync routine 897 - failure to do so was then causing hangs when trying to do tearfree video 898 or use a compositor. 899 900 * Prevent buffer leak if a non-fullscreen Window is closed with multiple 901 pending swap events. 902 903 * Fix offset transformation for fallback gradient paths. 904 https://bugs.freedesktop.org/show_bug.cgi?id=62198 905 906 * Prevent Glamor from crashing if misconfigured. 907 Thanks to Michel Dnzer. 908 909 * Prevent UXA from crashing if torn down during PreInit. 910 Thanks to Aaron Plattner. 911 912 * Prevent miscompilation with different functional units having different 913 compiler flags. Some functions were expected to be inlined and so 914 recompiled with the current target. However, some compilers were 915 choosing to emit subroutine calls instead without noticing that the 916 ABI was different between the caller and callee - causing corruption. 917 https://bugs.freedesktop.org/show_bug.cgi?id=62198 918 919 * Fix rendering of CompositeTriFan with recent Xorg. 920 921 * Apply the video src-offset fix highlighted in the last release! 922 A typo prevented the fix from working for gen4+. 923 https://bugs.freedesktop.org/show_bug.cgi?id=62343 924 925 * Fix rendering of multiple glyphs to very large destination surfaces 926 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1156387 927 928 * Fix scanline waits for Haswell 929 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1156679 930 931 932 Release 2.21.4 (2013-03-11) 933 =========================== 934 More bugs, more fixes, more releases. A minor new feature being introduced 935 is the runtime detection of CPU instructions sets along with specialised 936 paths to take advantage of the available CPU. 937 938 * Honour LinearFramebuffer for clumsy PowerXpress integration 939 940 * Disable read-read optimisations of mappings whilst the root 941 cause of a corruption issue remains elusive. 942 https://bugs.freedesktop.org/show_bug.cgi?id=61628 943 944 * Disable 8-bpp framebuffers in UXA as the regressions therein 945 remain unfixed. 946 947 * Restart vertex checks after lock contention 948 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1124576 949 950 * Handle Screen Pixmap recreation whilst exported via PRIME. 951 952 * Correct application of scale factors to video source offsets. 953 https://bugs.freedesktop.org/show_bug.cgi?id=61610 954 955 * Chain up CloseScreen so that resources are actually freed across regen 956 https://bugs.freedesktop.org/show_bug.cgi?id=56608 957 958 * Fix Haswell CRW PCI-IDs 959 960 * Handle batch submission failure during DRI copies 961 https://bugs.freedesktop.org/show_bug.cgi?id=61708 962 963 * Probe for kernel support of requested Screen depth 964 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1135403 965 966 * Correct GPU limits for early gen2 and gen3 architectures and prevent 967 an infinite recursion for particular image sizes. 968 969 970 Release 2.21.3 (2013-02-20) 971 =========================== 972 A few minor bugfixes, another point release. 973 974 * Fix tracking of DRI pixmaps and their backing bo across reparenting. If 975 we tried to execute a SwapBuffers after a Window was reparented, but 976 before the DRI client has updated its references, then we would end up 977 manipulating an exported pixmap without a flush flag set. In the worst 978 case, this would culminate in a segfault in the driver. 979 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1127497 980 981 * Restore the gen4 workarounds for flickering rendering - a few cases still 982 remain, as the root cause persists. 983 https://bugs.freedesktop.org/show_bug.cgi?id=60402 984 985 * Double check that the device has KMS enabled before claiming. This allows 986 X to gracefully fallback to VESA/fbdev rather than bailing out. 987 https://bugs.freedesktop.org/show_bug.cgi?id=60987 988 989 * Fix the UXA render programs for projective transforms on Ivybridge. 990 991 992 Release 2.21.2 (2013-02-10) 993 =========================== 994 Pass the brown paper bags, I need half a dozen or so. That seemingly 995 innocuous build fix with xorg-1.13 happened to have the little side-effect 996 of breaking glyph rendering with xorg-1.12 and older on 64-bit machines. 997 998 999 Release 2.21.1 (2013-02-10) 1000 =========================== 1001 A fix for a potential GPU hang on 945gm (GMA950) and earlier chipsets, 1002 along with backporting SNA to the packages found in stable distributions 1003 like Debian 6.0 (Squeeze). 1004 1005 * Cleanup compilation warnings from deblint, thanks to Paul Menzel 1006 1007 * Minor build improvements by Damien Lespiau. 1008 1009 * Disable generating span geometry for non-rectilinear spans on gen4 1010 in order to work around and prevent one class of render corruption. 1011 1012 * Prevent cache thrashing and severe performance degradation on LLC 1013 machines for streaming texture updates. However, note the effect was 1014 only observed on just one particular laptop. 1015 1016 * Fix alignment of subsurface proxies for old chipsets. 1017 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1120108 1018 1019 * Repair build against Xserver-1.6 and contemporary packages. 1020 1021 1022 Release 2.21.0 (2013-02-01) 1023 =========================== 1024 A few new features: 1025 1026 * Enable render acceleration for Haswell GT1/GT2. 1027 1028 * Enable multi-threaded rasterisation of trapezoids and fallback composition 1029 1030 * Utilise a new kernel interface (v3.9) for processing relocations 1031 1032 along with a few older features from the 2.20.x series: 1033 1034 * PRIME support for hotplug GPUs and hybrid systems 1035 1036 * Support for IvyBridge GT1 machines, aka HD2500 graphics. 1037 1038 * Stable 830gm/845g support, at last! 1039 1040 As usual we have a large number of bug fixes since the last release: 1041 1042 * Prevent a stray relocation being left after a buffer is removed from 1043 a batch, leading to GPU hangs. 1044 1045 * Make the driver more robust against its own failures to submit batches 1046 by falling back to software rendering. 1047 1048 * Fix emission of scanline waits for secondary pipes on gen6/7. Otherwise 1049 you may encounter GPU hangs in MI_WAIT_FOR_EVENT. 1050 1051 * Fix a missing corner pixel when drawing rectangles with PolyLines 1052 https://bugs.freedesktop.org/show_bug.cgi?id=55484 1053 1054 * Don't try to use Y-tiling colour buffers with mesa/i915c as mesa 1055 doesn't support them and wil fallback to software rendering 1056 1057 * Ensure that any cached mmaps are invalidated for a SwapBuffers 1058 https://bugs.freedesktop.org/show_bug.cgi?id=60042 1059 1060 * Correctly handle the composition of rotated displays too large for the 1061 3D pipeline 1062 https://bugs.freedesktop.org/show_bug.cgi?id=60124 1063 1064 * Fix the computation of the planar video frame size 1065 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1104180 1066 1067 1068 Release 2.20.19 (2013-01-20) 1069 ============================ 1070 A quick release as the last broke USB DisplayLink slave outputs badly. The 1071 performance of those displays was unusable due to an inadvertent change that 1072 caused us to flush the entire scanout over the USB for every drawing 1073 operation. 1074 1075 * Implement the GNOME Build API. A couple of minor changes to make 1076 integrators and distributors lives a little easier, or at least more 1077 consistent. 1078 1079 * Correctly offset inplace trapezoids for subwindows, such as the GTK+ 1080 close button after it has a background image uploaded. 1081 1082 * Explicitly prevent ring-switching for synchronized rendering to 1083 scanouts (for vsync). 1084 1085 * Clip dirty region to slave pixmaps (otherwise UDL is nigh unusuable) 1086 https://bugs.freedesktop.org/show_bug.cgi?id=59539 1087 1088 1089 Release 2.20.18 (2013-01-16) 1090 ============================ 1091 A bunch of miscellaneous fixes for assertion failures and various 1092 performance regressions when mixing new methods for offloads, along with 1093 a couple of improvements for rendering with gen4. 1094 1095 * Remove use of packed unnormalized texture coordinates on gen4/5 as 1096 these GPUs do not support unnormalized coordinates in the sampler. 1097 1098 * Remove dependency upon x86 asm for cross-building to unsupported 1099 architectures. 1100 https://bugs.gentoo.org/show_bug.cgi?id=448570 1101 1102 * Apply damage around PRIME updates in the correct order. 1103 1104 * Correctly read the initial backlight level for when the user 1105 overrides UXA's choice of backlight controller. 1106 1107 * Throttle UXA and prevent it queuing work much faster than the GPU can 1108 complete it. This realised itself in impossible performance figures and 1109 the entire display freezing for several seconds whlist the GPU caught 1110 up. One side effect is that it also caused the DDX to consume more 1111 memory than was required as it could not recycle buffers quick 1112 enough, and in some cases this produces a marked improvement in 1113 performance. Also note on gen2/3 this requires a new libdrm [2.4.41] 1114 in order to prevent a bug causing the DDX to fallback to swrast. 1115 1116 Release 2.20.17 (2012-12-26) 1117 ============================ 1118 A minor update to prepare for co-operating with the kernel over managing 1119 stability on 830gm/845g. On this pair of chipsets, the kernel will perform 1120 an extra copy of the batchbuffer into reserved memory, which prevents them 1121 from randomly dying. However, that extra copy does have a noticeable 1122 impact upon throughput, so we also have a mechanism for userspace to 1123 opt-out of the kernel workaround and take responsibility for ensuring its 1124 batches are coherent. 1125 1126 * Build fixes against xorg-1.14 1127 https://bugs.freedesktop.org/show_bug.cgi?id=58552 1128 https://bugs.freedesktop.org/show_bug.cgi?id=58406 1129 1130 * Fixed the origin of cropped (textured) video windows (Xv and XvMC) 1131 https://bugs.freedesktop.org/show_bug.cgi?id=23033 1132 1133 * Fix potential corruption when using images larger than ~1GiB 1134 1135 1136 Release 2.20.16 (2012-12-15) 1137 ============================ 1138 Rejoice! We have found a trick to make 830gm/845g stable at long last. 1139 Ever since the switch to GEM and dynamic video memory, those early 1140 second generation chipsets have been plagued by instability. The lack of 1141 flushing cachelines from the CPU to GMCH was eventually solved by using 1142 an undocmented bit, but 830/845 were still hanging under memory pressure. 1143 These deaths were all due to garbage finding its way into the command 1144 streamer, and they go away if we take a leaf out of the original driver 1145 and never reuse those pages for anything else. So for the first time 1146 ever, I have been able to complete running the test suite on an 845g, 1147 even whilst thrashing the page and buffer caches! 1148 1149 * Run the SF stage as single-threaded on gen4 to workaround a few issues 1150 https://bugs.freedesktop.org/show_bug.cgi?id=57410 1151 1152 * Keep the scanout SURFACE_STATE separate to avoid overriding its 1153 memory access control on gen6/7 (i.e. writes to the scanout need to 1154 be kept out of the render cache) 1155 1156 * Tune batch flushing after an operation to an exported surface under a 1157 compositor. 1158 1159 * Make sure the source is on the CPU for inplace composition of trapezoids 1160 using the CPU 1161 https://bugs.freedesktop.org/show_bug.cgi?id=56825 1162 1163 * Immediately flush in the block hander after a split batch to reduce 1164 latency between the two halves of an operation. 1165 https://bugs.freedesktop.org/show_bug.cgi?id=51718 1166 1167 * Install a fallback config if we fail to install the desired config 1168 at VT switch (i.e. booting, after resume with 3 incompatible pipes on 1169 Ivybridge) 1170 1171 * Pin batches to avoid CS incoherence on 830/845 1172 https://bugs.freedesktop.org/show_bug.cgi?id=26345 1173 1174 1175 Release 2.20.15 (2012-12-03) 1176 ============================ 1177 And lo, enabling more of the common acceleration paths for gen4 revealed 1178 another lurking bug - something is wrong with how we prepare Y-tiling 1179 surfaces for rendering. For the time being, we can surreptiously disable 1180 them for gen4 and avoid hitting GPU hangs. 1181 1182 * Avoid clobbering the render state after failing to convert the 1183 operation to use the blitter. 1184 https://bugs.freedesktop.org/show_bug.cgi?id=57601 1185 1186 * Disable shadow tracking upon server regeneration, and so fix a crash 1187 if you restart the server whilst a RandR transform (e.g. rotation) is 1188 in effect. 1189 https://bugs.freedesktop.org/show_bug.cgi?id=52255 1190 https://bugs.freedesktop.org/show_bug.cgi?id=56608 1191 1192 1193 Release 2.20.14 (2012-11-26) 1194 ============================ 1195 The highlight of this release is gen4, from 965g to gm45. Quite an old 1196 bug surfaced in the shader assembly, sparking a chance to review a few 1197 design choices within that backend and experiment on fresh ways to 1198 workaround the remaining issues. 1199 1200 * Avoid using inplace XOR'ed uploads for very large buffers 1201 https://bugs.freedesktop.org/show_bug.cgi?id=57031 1202 1203 * Fix the gen4/5 opacity shader 1204 https://bugs.freedesktop.org/show_bug.cgi?id=57054 1205 1206 * Queue a pending vblank request after flip completion 1207 https://bugs.freedesktop.org/show_bug.cgi?id=56423 1208 1209 * Avoid migrating an uninitialised pixmap for use as a render source 1210 https://bugs.freedesktop.org/show_bug.cgi?id=47597 1211 1212 * Improve handing of texture fallbacks for 830/845. 1213 https://bugs.freedesktop.org/show_bug.cgi?id=57392 1214 1215 1216 Release 2.20.13 (2012-11-11) 1217 ============================ 1218 Nothing but bug fixes. Many thanks to everyone who took the time to 1219 report their issues, and for their help in improving the driver. 1220 1221 * Sanity check the platform probe points to our expected i915 device 1222 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1069031 1223 1224 * Prevent 16-bit overflow for computing the sample area to upload of 1225 sources for render operations 1226 https://bugs.freedesktop.org/show_bug.cgi?id=56324 1227 1228 * Clamp the drawable box for migration to prevent 16-bit overflow 1229 https://bugs.freedesktop.org/show_bug.cgi?id=56591 1230 1231 * Disable RandR hotplug events if Xinerama is enabled and thereby prevent 1232 a crash upon hotplug 1233 https://bugs.freedesktop.org/show_bug.cgi?id=55260 1234 1235 * Call ValidatePicture before attempting to flatten the alphamaps 1236 https://bugs.freedesktop.org/show_bug.cgi?id=56367 1237 1238 * Clip the trapezoid correctly if it ends on the boundary pixel 1239 https://bugs.freedesktop.org/show_bug.cgi?id=56395 1240 1241 * Make sure the pipeline choice is propagated to the scanline wait 1242 across a batch flush 1243 https://bugs.freedesktop.org/show_bug.cgi?id=47597 1244 1245 * Set the valid drawable box when choosing placement of BLT composite ops 1246 https://bugs.freedesktop.org/show_bug.cgi?id=47597 1247 1248 * Prevent use-after-free when promoting a partial-GPU bo to a full-GPU bo 1249 https://bugs.freedesktop.org/show_bug.cgi?id=56591 1250 1251 * gen4 opacity spans require the per-rectangle workaround 1252 https://bugs.freedesktop.org/show_bug.cgi?id=55500 1253 1254 * Prevent use of invalid damage pointers when redirecting rendering 1255 https://bugs.freedesktop.org/show_bug.cgi?id=56785 1256 1257 1258 Release 2.20.12 (2012-10-20) 1259 ============================ 1260 More bug reports, more bug fixes! Perhaps the headline feature is 1261 that with a secure batches, coming to a 3.8 kernel near you, we may 1262 finally have the ability to perform updates to the scanout synchronized 1263 to the refresh rate on later SandyBridge and IvyBridge chipsets. It comes 1264 at quite a power cost as we need to keep the GPU out of its power saving 1265 modes, but it should allow legacy vsync to function at last. But this 1266 should allow us to address a longstanding issue with tearing on 1267 SandyBridge+. 1268 1269 * Fix component-alpha rendering on IvyBridge, for example subpixel 1270 antialiased glyphs. 1271 https://bugs.freedesktop.org/show_bug.cgi?id=56037 1272 1273 * Flush before some "pipelined" state changes on gen4. The evidence is 1274 that the same flushes as required on gen5+ are also required for gen4. 1275 https://bugs.freedesktop.org/show_bug.cgi?id=55627 1276 1277 * Prevent a potential crash when forcing a stall on a busy CPU bo 1278 https://bugs.freedesktop.org/show_bug.cgi?id=56180 1279 1280 [Release 2.20.11 contained a typo causing UXA to fail immediately.] 1281 1282 Release 2.20.10 (2012-10-14) 1283 ============================ 1284 The last couple of weeks have been fairly retrospective, a dive into 1285 prehistory tidying up the earlier generations which lay languishing as 1286 the core progressed and lead to a number of annoying core bugs being 1287 fixed. 1288 1289 * Release DRM master earlier during shutdown so switching between 1290 multiple X servers works automatically. 1291 https://bugs.freedesktop.org/show_bug.cgi?id=55446 1292 1293 * Suppress error propagation from DRI2GetMSC and behave as if the pipe 1294 was simply off to avoid unexpected errors in the clients 1295 https://bugs.freedesktop.org/show_bug.cgi?id=55395 1296 1297 * A few fixes to i8xx batch emission, ensuring that the GPU is always 1298 in a valid state. 1299 https://bugs.freedesktop.org/show_bug.cgi?id=55455 1300 1301 * Prevent a use-after-free during UXA shutdown due to inspecting 1302 the glamor flags after the glamor interface had been freed. 1303 1304 * Prevent a crash combining TearFree and rotations. 1305 https://bugs.freedesktop.org/show_bug.cgi?id=55527 1306 1307 * Correct a missing damage upload along PutImage after using the CPU bo 1308 as a source for the GPU. 1309 https://bugs.freedesktop.org/show_bug.cgi?id=55508 1310 1311 * Fix compilation for older glibc without O_CLOEXEC 1312 https://bugs.freedesktop.org/show_bug.cgi?id=55577 1313 1314 * Fix out-of-tree builds failing to recompile the gen4 assemblies 1315 https://bugs.freedesktop.org/show_bug.cgi?id=55645 1316 1317 * Fix non-standard build host configuration handling for intel-gen4asm 1318 https://bugs.freedesktop.org/show_bug.cgi?id=55646 1319 1320 * Fix a potential batch buffer overflow when replacing the last BLT fill 1321 operation with a copy 1322 https://bugs.freedesktop.org/show_bug.cgi?id=55700 1323 1324 * Flush the render pipeline more frequently on Ironlake as not all 1325 pipelined state changes are. 1326 https://bugs.freedesktop.org/show_bug.cgi?id=51422 1327 1328 * Detect when we need to read the destination for the background raster 1329 op during fallbacks. 1330 https://bugs.freedesktop.org/show_bug.cgi?id=55810 1331 1332 * Avoid a potential deference of an invalid CPU mmap after doing an 1333 inplace tiled upload. 1334 https://bugs.freedesktop.org/show_bug.cgi?id=55812 1335 1336 * Prevent sign extension when packing the upload data for CopyPlane 1337 https://bugs.freedesktop.org/show_bug.cgi?id=55823 1338 1339 * Fix some render corruption with a UDL slave output and pageflipping 1340 1341 1342 Release 2.20.9 (2012-09-29) 1343 =========================== 1344 And so it came to pass that a critical bug was uncovered in UXA. The 1345 kernel does not like to pageflip when the pipe is off, yet due to the 1346 delayed nature of a pageflip and the relaxed checking performed by UXA, 1347 we could request a pageflip after turning off the display (DPMS). The 1348 kernel rejected that pageflip and the error handling path failed to 1349 restore sanity, and when the screen came back it was stuck on the image 1350 seen before it went to sleep. (Note that there are also some related 1351 kernel bugs, but this update should prevent the most conspicious of the 1352 freezes.) Many thanks to Timo Aaltonen for his efforts in tracking down 1353 the issue. 1354 1355 In other news: 1356 1357 * Prepare for xorg-1.14, the api is being tweaked again. 1358 1359 * Handle early FreeScreen in UXA. 1360 https://bugs.freedesktop.org/show_bug.cgi?id=55346 1361 1362 * Reenable XvMC support 1363 1364 * Do not replace the GPU bo when uploading into the shadow/CPU copy 1365 https://bugs.freedesktop.org/show_bug.cgi?id=54978 1366 1367 * Fix use of an uninitialised GC when drawing glyphs to a depth=1 pixmap 1368 1369 1370 Release 2.20.8 (2012-09-16) 1371 =========================== 1372 Another new small feature, another new release. And a few more bugs 1373 fixed as well! But what is this new feature, do I hear you ask? Why, it 1374 is nothing less than enabling the ValleyView SDV! The lucky person to 1375 have their hands on one will now be able to enjoy X in full TechniColor. 1376 1377 For the rest of us, a few more bugs were fixed with interesting 1378 combinations of software and rendering patterns. 1379 1380 * Add an extra layer of defence against trying to use a non-GEM device 1381 with UXA. This should already be taken care of with the new probe, 1382 but the extra sanity check already existed in the code but was doing 1383 nothing. 1384 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/962892 1385 1386 * Fix computation of valid CRTCs bitmask for ZaphodHead 1387 Some systems can only handle certain outputs on certain pipes 1388 (Screens), and this information was not being propagated through to X 1389 and randr correctly, breaking valid configurations and not detecting 1390 invalid configurations correctly. 1391 1392 * Disable global glyph caching with ZaphodHeads. 1393 The glyph privates need to be Screen private, but at the moment are 1394 global leading to conflicts and invalid rendering with multiple heads. 1395 https://bugs.freedesktop.org/show_bug.cgi?id=54707 1396 1397 * Prevent direct read back of unmappable buffers 1398 https://bugs.freedesktop.org/show_bug.cgi?id=54808 1399 1400 * Tile large uploads whilst replacing the alpha channel 1401 https://bugs.freedesktop.org/show_bug.cgi?id=54808 1402 1403 * Correct the source offset when converting a RENDER composite 1404 operation into a BLT composite operation. 1405 https://bugs.freedesktop.org/show_bug.cgi?id=54868 1406 1407 * Correct a minor typo in flattening alphamaps which caused the 1408 replacement pixmap to often end up with a height of zero. 1409 https://bugs.gentoo.org/show_bug.cgi?id=434860 1410 1411 * Don't discard the CPU damage if only part of is being replaced. 1412 This is most evident when combining software renders like Opera with 1413 accelerated rendering. 1414 https://bugs.freedesktop.org/show_bug.cgi?id=54937 1415 1416 Release 2.20.7 (2012-09-08) 1417 =========================== 1418 Continuing the flurry of releases, this week saw the release of 1419 xorg-1.13 bringing with it the first steps towards hotpluggable gpu 1420 support and the ability to offload DRI rendering onto other GPUs. In 1421 light of that advance, this release includes the support code by Dave 1422 Airlie to integrate PRIME into xf86-video-intel and make those new 1423 features available. 1424 1425 Aside from landing PRIME, a few other bugs were fixed since 2.20.6: 1426 1427 * Fix framebuffer leak on server regeneration 1428 1429 * Fix texture cache flushing on IvyBridge and Kwin with plastique 1430 https://bugs.freedesktop.org/show_bug.cgi?id=54488 1431 1432 * Redirect large solid fills on SandyBridge+. By large I mean greater 1433 than 8192 or 16384 pixels on SandyBridge and IvyBridge respectively. 1434 https://bugs.freedesktop.org/show_bug.cgi?id=54134 1435 1436 * Fix up backlight option handling in the manpage and uxa. 1437 https://bugs.freedesktop.org/show_bug.cgi?id=54397 1438 1439 * Unbreak ZaphodHeads. 1440 https://bugs.freedesktop.org/show_bug.cgi?id=52438 1441 1442 Release 2.20.6 (2012-09-02) 1443 =========================== 1444 A serious bug that caused a crash on SandyBridge and IvyBridge when 1445 mixing CPU and GPU operations on the same buffer, and an annoyance from 1446 bad scheduling of windowed swapbuffer updates causing low framerates and 1447 jitter. Plus the usual smattering of assertion fixes and a long standing 1448 issue with incoherent page access to a streaming buffer. 1449 1450 * Low frame rates in Blobby Valley when "fullscreen" 1451 https://bugs.freedesktop.org/show_bug.cgi?id=54274 1452 1453 * Incoherent concurrent access with the CPU and GPU 1454 https://bugs.freedesktop.org/show_bug.cgi?id=51422 1455 https://bugs.freedesktop.org/show_bug.cgi?id=52299 1456 1457 * Add Option "Backlight" to override automatic selection of the 1458 backlight interface. 1459 1460 * Avoid overwriting the composite operation info when testing if we 1461 can transfer the operation to the BLT. 1462 1463 Release 2.20.5 (2012-08-26) 1464 =========================== 1465 Another silly bug found, another small bugfix release. The goal was for 1466 the driver to bind to all Intel devices supported by the kernel. 1467 Unfortunately we were too successful and started claiming Pouslbo, 1468 Medfield and Cedarview devices which are still encumbered by propietary 1469 IP and not supported by this driver. 1470 1471 Bugs fixed since 2.20.4: 1472 1473 * Only bind to Intel devices using the i915 kernel module 1474 1475 * Regression in the bitmap-to-region code, e.g. icewm window buttons 1476 https://bugs.freedesktop.org/show_bug.cgi?id=53699 1477 1478 Release 2.20.4 (2012-08-18) 1479 =========================== 1480 Continuing the small bugfix releases, the only real feature is initial 1481 enabling for Haswell for the purpose of rendering verification and 1482 validation - by no means is it complete! 1483 1484 Bugs fixed since 2.20.3: 1485 1486 * Some potential errors along failure paths found by a static analyser 1487 with the help of Zdenek Kablac. 1488 1489 * Eliminate zero-sized rectangles from PolyFillRectangles as the code 1490 assumes that they did not exist and so caused corruption. 1491 1492 * Remove the UXA warning for failing to tile the front buffer if it is 1493 disallowed by hardware, and so expected. 1494 1495 * Fix the validation of the XV pipe parameter. 1496 1497 * Fix 8x8 tiled pattern fills 1498 https://bugs.freedesktop.org/show_bug.cgi?id=53353 1499 1500 * Fix compile failure when using --with-builderstring 1501 1502 * Restore w/a flush for gen4 fill/copy/video, fortunately rare 1503 operations as at least for fill/copy we prefer to use the BLT. 1504 https://bugs.freedesktop.org/show_bug.cgi?id=53119 1505 1506 * Restore preferred use of the RENDER ring for SNB+ DRI copies. 1507 1508 Release 2.20.3 (2012-08-04) 1509 =========================== 1510 Just a minor bugfix for gen4 chipsets (965gm, gm45 and friends) that 1511 crept into 2.20.2. As an added bonus, the pessimistic workaround for a 1512 GPU hang on gen4 has been relaxed and the shaders have been overhauled 1513 which should pave the way to eliminating the last of the uncommon CPU 1514 operations, along with immediately realising a small perforamnce 1515 improvement. 1516 1517 Bugs fixed since 2.20.2: 1518 1519 * Update DPMS bookkeeping after modeset 1520 https://bugs.freedesktop.org/show_bug.cgi?id=52142 1521 1522 * Avoid overlapping gpu/cpu damage after ignoring cpu damage in the 1523 consideration of placement for the operation. 1524 1525 * Enable acceleration by default on 830gm/845g. The GMCH on this pair 1526 of chipsets is notoriously incoherent, so the GPU is almost certainly 1527 going to hang at some point, though unlikely to hang the system and 1528 should automatically disable acceleration (and thence behave 1529 identically as if the acceleration was disabled from the start). 1530 Option "NoAccel" can be used to disable all 2D acceleration and 1531 Option "DRI" can be used to disable all 3D acceleration. 1532 https://bugs.freedesktop.org/show_bug.cgi?id=52624 1533 1534 * Fix vertex bookkeeping for gen4 that was causing corruption in the 1535 command stream. 1536 1537 Release 2.20.2 (2012-07-27) 1538 =========================== 1539 For the last 9 months, since 2.16.901, we have been shipping a driver that 1540 does not work on IvyBridge GT1 systems (HD2500 graphics); we were telling 1541 the GPU to use an invalid number of threads for the pixel shader and this 1542 in turned caused the GPU to hang. 1543 1544 Also fixed since the last release just a few days ago: 1545 1546 * Support for the gmux backlight controller on Apple laptops 1547 https://bugs.freedesktop.org/show_bug.cgi?id=52423 1548 1549 * Fix X -configure not to list this driver as matching any Intel device, 1550 just the VGA class devices will do! 1551 1552 * A crash in SNA when repeatedly switching xrandr rotations 1553 1554 * Corruption in SNA observed in kwin on IvyBridge 1555 https://bugs.freedesktop.org/show_bug.cgi?id=52473 1556 1557 Release 2.20.1 (2012-07-22) 1558 =========================== 1559 A week in, grab the brown paper bags, for it is time to reveal a couple 1560 of critical bugs that spoilt the 2.20.0 release. 1561 1562 Firstly we have the restoration of DRI for i810. I am sure that the 1563 solitary user will be overjoyed in a couple of years when a new xserver 1564 is forced upon him. That enjoyment will be short-lived when as no actual 1565 acceleration remains, not even shadow, for the chipset. 1566 1567 Perhaps a little more wildly felt, I hope!, will be that the SNA 1568 fallbacks were broken on 64-bit machines if they required clipping. One 1569 little misplaced cast of a pointer, and the screen is filled with 1570 corruption. 1571 1572 Among the other tweaks this week: 1573 1574 * A bug affecting gen4 handling of trapezoids was fixed, and CPU 1575 overhead reduced. 1576 https://bugs.freedesktop.org/show_bug.cgi?id=52158 1577 1578 * A fix for a bug causing corruption of a DRI2 unredirected client 1579 window that was resized whilst under a compositor. 1580 1581 * Support for snoopable buffers on non-LLC architectures, coming to 1582 a future kernel. The aim to accelerate transfers between the CPU 1583 and the GPU, in particular to dramatically improve readback 1584 performance, and to further minimise clflushes. 1585 1586 * Improvement to the composite performance on GT2 SandyBridge and 1587 IvyBridge devices, in particular the render copy is significantly 1588 improved. 1589 1590 * Improved handling for when acceleration is disabled, including 1591 permitting DRI2 to remain supported even if the X server believes 1592 the GPU wedged. 1593 1594 * Shadow support was dropped from UXA as it was neither complete nor 1595 correct, use SNA instead. 1596 1597 Release 2.20.0 (2012-07-15) 1598 =========================== 1599 First the big news, a new acceleration method that aims to be faster and 1600 consume far less CPU than UXA is now available for selection at runtime. 1601 This snazzy new architecture can be selected through use of 1602 Option "AccelMethod" "sna" 1603 in your xorg.conf. Whilst it has been under development for some time, it 1604 has not yet had the same degree of widespread testing of UXA, so tread 1605 lightly. Try it and if you spot anything that can be improved, please do 1606 report a bug. 1607 1608 Otherwise we have the usual smattering of bug fixes for UXA: 1609 1610 * Use a white source whilst adding glyphs to the glyph mask 1611 (This fixes blank glyphs if using a font that mixes ARGB and A glyphs.) 1612 1613 * Avoid fallbacks for glyph-to-dst in e.g. gnome-terminal 1614 https://bugs.freedesktop.org/show_bug.cgi?id=50508 1615 1616 * Force unused outputs off when VT switching 1617 https://bugs.freedesktop.org/show_bug.cgi?id=50772 1618 1619 * Copy the fbcon across to the Screen pixmap at startup. 1620 (This patch has been kicking around in the distributions for years.) 1621 1622 * Many missed malloc failures checks and forgotten frees found by a static 1623 analyzer. Thanks Zdenek Kabelac! 1624 1625 * Leak of the back buffer when terminating an application after pageflipping 1626 https://bugs.freedesktop.org/show_bug.cgi?id=50670 1627 1628 * Double check that the pipe is on before emitting a WAIT_ON_EVENT. 1629 In conjunction with an uptodate kernel, this should eliminate any 1630 hangs when changing resolutions or adding/removing displays. 1631 https://bugs.freedesktop.org/show_bug.cgi?id=50668 1632 1633 * Update to new Xorg APIs. Future proofing for the next generation of 1634 hotplug Xorg display servers. 1635 1636 Many thanks to everyone who has reported a bug and otherwise helped to 1637 improve the driver. 1638 1639 Release 2.19.0 (2012-04-29) 1640 =========================== 1641 More stability fixes for UXA and support for another variant of IvyBridge. 1642 Given the severity of the stability fixes, I strongly recommend everybody 1643 to upgrade to 2.19.0. 1644 1645 * Prevent waiting on scanlines whilst not in control of the VT and therefore 1646 whilst referencing foreign CRTC configurations. 1647 1648 * Pixmap (and bo leak) during fallback glyph composition 1649 1650 * Remove broken acceleration for rendering glyphs directly upon the 1651 destination pixmap, exposed by cairo-1.12.0 (and coincidentally fix 1652 another Pixmap leak upon fallback handling). 1653 1654 * Add support for Ivy Bridge GT2 Server chipset [PCI id 0x016a] 1655 1656 * Remove broken damage flushing with CompositeRectangles 1657 https://bugs.freedesktop.org/show_bug.cgi?id=32547 1658 1659 * Fix crash upon server start with multiple monitors 1660 https://bugs.freedesktop.org/show_bug.cgi?id=47395 1661 1662 * Fix composition issues resulting from overly aggressive Pixmap reuse 1663 https://bugs.freedesktop.org/show_bug.cgi?id=47345 1664 1665 Release 2.18.0 (2012-02-24) 1666 =========================== 1667 Time passes, a few more bugs have crept out of the woodwork that are a 1668 compelling reason to update. 1669 1670 Bugs fixed in this release (compared to 2.17.0) 1671 ----------------------------------------------- 1672 1673 * Limit maximum object size so that all of the source, mask and 1674 destination can be mapped into the aperture simultaneously by basing the 1675 limit on the mappable aperture size rather than the size of the total 1676 GATT. 1677 1678 * Incorrect clipping of polygons 1679 https://bugs.freedesktop.org/show_bug.cgi?id=43649 1680 Regression from 2.15.901 1681 1682 * Limit number of VMA cached to avoid hitting the per-process VMA limit 1683 There still is a residual bug in that we seem to have so many objects 1684 floating around in the first place and that still leads to exhaustion 1685 of system limits. 1686 https://bugs.freedesktop.org/show_bug.cgi?id=43075 1687 https://bugs.freedesktop.org/show_bug.cgi?id=40066 1688 1689 * Latency in processing user-input during continuous rendering 1690 1691 Release 2.17.0 (2011-11-16) 1692 ============================== 1693 A few months have passed, and we have accumulated a surprising number of 1694 bug fixes. Oops! We would strongly encourage everyone to upgrade. 1695 1696 Bugs fixed in this snapshot (compared to 2.16.902) 1697 -------------------------------------------------- 1698 1699 * Video clobbering composite batch state 1700 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=635953 1701 1702 Snapshot 2.16.902 (2011-11-13) 1703 ============================== 1704 This is the second release candidate in preparation for the upcoming 1705 2.17.0 release. We will appreciate any feedback we can get from 1706 testing of this snapshot, and thanks to everyone who tested and reported 1707 upon issues in the last snapshot. 1708 1709 A very old bug demonstrating that nobody has ever used alpha maps, and a 1710 couple of more recent mistakes were found. 1711 1712 Bugs fixed in this snapshot (compared to 2.16.901) 1713 -------------------------------------------------- 1714 1715 * Incorrect reuse of surface bindings within a batch for multiple formats 1716 https://bugs.freedesktop.org/show_bug.cgi?id=40926 1717 1718 * Nothing was rendered for text with procedural sources 1719 https://bugs.freedesktop.org/show_bug.cgi?id=31819 1720 1721 * Handle fallbacks involving alpha maps 1722 1723 Snapshot 2.16.901 (2011-10-30) 1724 ============================== 1725 This is the first release candidate in preparation for the upcoming 1726 2.17.0 release. We will appreciate any feedback we can get from 1727 testing of this snapshot. 1728 1729 The basis of this release are to push out a couple of critical stability 1730 fixes for SandyBridge and IvyBridge. There is very little else to see 1731 here. Those 200+ other commits do not exist... 1732 1733 Bugs fixed in this snapshot (compared to 2.16.0) 1734 -------------------------------------------------- 1735 1736 * Workaround blitter hang on SandyBridge and IvyBridge 1737 https://bugzilla.kernel.org/show_bug.cgi?id=27892 1738 https://bugs.freedesktop.org/show_bug.cgi 1739 1740 * Workaround pipe control issues on SandyBridge 1741 1742 * Use correct maximum PS thread count on IvyBridge 1743 1744 * Protect against failed pixmap allocation for XV 1745 https://bugs.freedesktop.org/show_bug.cgi?id=40439 1746 1747 Release 2.16.0 (2011-08-09) 1748 ============================== 1749 A new quarter, a new release! The key feature of this release, looking past 1750 the bug fixes, is the enabling of IvyBridge acceleration. We have also fixed 1751 many bugs and graphical glitches and would encourage everyone to upgrade. 1752 1753 Bugs fixed in this snapshot (compared to 2.15.901) 1754 -------------------------------------------------- 1755 1756 * Build fix for xserver-1.7.7 1757 1758 Snapshot 2.15.901 (2011-07-30) 1759 ============================== 1760 This is the first release candidate in preparation for the upcoming 1761 2.16.0 release. We will appreciate any feedback we can get from 1762 testing of this snapshot. 1763 1764 The highlight of this snapshot is the full enabling of IvyBridge with 1765 acceleration for Render and Xv, along with handling of the shared render 1766 buffer allocations required for Mesa. Also of note is that deep-color 1767 support is enabled (for all chipsets), which allows you to drive your 1768 30-bit monitor at its native colour depth. 1769 1770 Bugs fixed in this snapshot (compared to 2.15.0) 1771 -------------------------------------------------- 1772 1773 * Misuse of the Resource database causing crashes after DRI clients close 1774 https://bugs.freedesktop.org/show_bug.cgi?id=37700 1775 1776 * Crash on large strings 1777 https://bugs.freedesktop.org/show_bug.cgi?id=36860 1778 1779 * Incorrect rendering for some core drawing operations 1780 http://bugs.freedesktop.org/show_bug.cgi?id=28768 1781 http://bugs.freedesktop.org/show_bug.cgi?id=28798 1782 http://bugs.freedesktop.org/show_bug.cgi?id=28908 1783 http://bugs.freedesktop.org/show_bug.cgi?id=29401 1784 1785 * Crash in Xv due to insufficient checks on batch space 1786 https://bugs.freedesktop.org/show_bug.cgi?id=36319 1787 1788 Release 2.15.0 (2011-04-14) 1789 ============================== 1790 We are pleased to announce this major release of the xf86-video-intel 1791 driver, roughly on schedule at 3 months since 2.14.0. With the many bug 1792 fixes in this release, we encourage everyone to upgrade to 2.15. 1793 1794 The priority for this quarter has been simply to be unexciting and stabilise 1795 the driver further, seeking to capitalise upon the improvements elsewhere 1796 in the stack. 1797 1798 Bugs fixed in this snapshot (compared to 2.14.903) 1799 -------------------------------------------------- 1800 1801 * Turn off relaxed fencing by default for older chipsets 1802 This was continuing to destabilize those system, so for the release 1803 we disabled the feature. If you wish to help us debug this, you can 1804 re-enable the optimisation with Option "RelaxedFencing" "True". 1805 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=36147 1806 1807 * Build fix for xserver-1.7.7 1808 1809 * KDE glitches on SNB 1810 [Technically fixed in the previous snapshot, but I'm really pleased 1811 that this got fixed in time for the release!] 1812 https://bugs.freedesktop.org/show_bug.cgi?id=35808 1813 1814 1815 Snapshot 2.14.903 (2011-04-11) 1816 ============================== 1817 This is the third release candidate in preparation for the upcoming 1818 2.15.0 release. We will appreciate any feedback we can get from 1819 testing of this snapshot. 1820 1821 There was a bit of churn since 2.14.902 as a potential fix for a 1822 performance regression was tried but had to reverted when it was found to 1823 cause glitches running Compiz on SandyBridge. Otherwise, there were just a 1824 couple of fixes for building against old xservers and running on an 1825 obscure chipset. 1826 1827 Bugs fixed in this snapshot (compared to 2.14.902) 1828 -------------------------------------------------- 1829 1830 * Prevent issuing an invalid scanline wait command 1831 https://bugs.freedesktop.org/show_bug.cgi?id=35576 1832 1833 * The 946GZ in not a 945, but a 965. 1834 https://bugs.freedesktop.org/show_bug.cgi?id=35854 1835 1836 * Fix tile sizes for gen2 (finally). 1837 1838 * Allow building of recent dri2 changes against old xservers. 1839 1840 1841 Snapshot 2.14.902 (2011-03-29) 1842 ============================== 1843 This is the second release candidate in preparation for the upcoming 1844 2.15.0 release. We will appreciate any feedback we can get from 1845 testing of this snapshot. 1846 1847 As befits testing of release candidates, no major regression was found and 1848 a couple more bugs have been fixed. 1849 1850 Bugs fixed in this snapshot (compared to 2.14.901) 1851 -------------------------------------------------- 1852 1853 * Clients disappearing with pending swaps 1854 1855 * Incorrect clipping of Xv output on i915 across extended desktops 1856 https://bugs.freedesktop.org/show_bug.cgi?id=35346 1857 1858 * Introduction of a LinearFramebuffer option. (Defaults to tiled for 1859 performance and power saving.) 1860 1861 1862 Snapshot 2.14.901 (2011-03-02) 1863 ============================== 1864 This is the first release candidate in preparation for the upcoming 1865 2.15.0 release. We will appreciate any feedback we can get from 1866 testing of this snapshot. 1867 1868 Still no further along my grandiose plans to improve Render performance, 1869 aside from the performance tuning lower in the stack, instead we have had 1870 a steady stream of bug fixes. 1871 1872 Bugs fixed in this snapshot (compared to 2.14.0) 1873 ------------------------------------------------ 1874 1875 * Green pixels within partially off-screen video playback 1876 https://bugs.freedesktop.org/show_bug.cgi?id=24767 1877 1878 * Defer creation of the glyph cache to generation startup 1879 https://bugs.freedesktop.org/show_bug.cgi?id=33412 1880 1881 * Incorrect maximum addresses for video decoder state 1882 https://bugs.freedesktop.org/show_bug.cgi?id=34017 1883 1884 * Failure to handle oversized temporary surfaces 1885 https://bugs.freedesktop.org/show_bug.cgi?id=34399 1886 1887 * Relaxed tiling corruption on gen2 1888 1889 * Crash when destroying a foreign DRI drawable 1890 https://bugs.freedesktop.org/show_bug.cgi?id=34787 1891 1892 1893 Release 2.14.0 (2011-01-07) 1894 =========================== 1895 We are pleased to announce this major release of the xf86-video-intel 1896 driver, on schedule at 3 months since 2.13.0. With the many bug fixes 1897 in this release, we encourage everyone to upgrade to 2.14. 1898 1899 The most notable feature of this release is the inclusion of acceleration 1900 support, both RENDER and XVIDEO, for Sandy Bridge; note that this requires 1901 a 2.6.37 kernel. In improving the acceleration code paths to support Sandy 1902 Bridge, we were also able to improve the performance of the general i965+ 1903 RENDER acceleration. For example on i3, glyph (aa10 and rgb10) performance 1904 is about 3x faster, as is performing small copies between windows, with the 1905 improvement becoming negligible once you hit around 100 pixels square. 1906 1907 1908 Snapshot 2.13.903 (2010-01-04) 1909 ============================== 1910 This is the second release candidate in preparation for the upcoming 1911 2.14.0 release, and if no showstoppers turn up in wider testing will 1912 become the next release. Besides the usual bug fixes, we've included 1913 patches by Mario Kleiner to improve vblank handing which both improve the 1914 timing accuracy and remove a few potential races -- provided you also 1915 have the corresponding fixes in the kernel. 1916 1917 Bug fixes 1918 --------- 1919 1920 * Crash on hot-unpluging with an active fullscreen GL application, e.g. a 1921 compositing WM or video player 1922 https://bugs.freedesktop.org/show_bug.cgi?id=32770 1923 1924 * Freeze upon maximising client-side software renderers, e.g. flash. 1925 https://bugs.freedesktop.org/show_bug.cgi?id=31367 1926 1927 * Fix confusion over G35 generation 1928 https://bugs.freedesktop.org/show_bug.cgi?id=32478 1929 1930 1931 Snapshot 2.13.902 (2010-12-10) 1932 ============================== 1933 This is the first release candidate in preparation for the upcoming 1934 2.14.0 release. Sandybridge support should be now be ready for use, 1935 and we will appreciate any feedback we can get from this snapshot. 1936 Improving the code base for Sandybridge should also have had knock 1937 on effects for earlier chips as well, in particular Ironlake and to 1938 a lesser extent i965. 1939 1940 New requirements compared to 2.13 1941 --------------------------------- 1942 * Librdrm >= 2.4.23 1943 1944 Bug fixes 1945 --------- 1946 1947 * Crash after failing to allocate memory 1948 https://bugs.freedesktop.org/show_bug.cgi?id=31487 1949 1950 * EFAULT during pwrite 1951 https://bugs.freedesktop.org/show_bug.cgi?id=29752 1952 1953 * Mark outputs as on and restore backlight after mode-set 1954 1955 * A hang with i965+ with newer kernels. 1956 1957 1958 Snapshot 2.13.901 (2010-11-05) 1959 ============================== 1960 This is an intermediate snapshot of ongoing driver development. The 1961 primary purpose of this snapshot is to capture some recent 1962 improvements, (particularly in Sandybridge support), for further 1963 testing. 1964 1965 Release 2.13.0 (2010-09-30) 1966 =========================== 1967 We are pleased to announce this major release of the xf86-video-intel 1968 driver, on schedule at 3 months since 2.12.0. With the many bug fixes 1969 in this release, we encourage everyone using 2.12 to upgrade to 2.13. 1970 1971 [This release is functionally identical to the earlier 2.12.902 1972 release candidate.] 1973 1974 New requirements compared to 2.12 1975 --------------------------------- 1976 * Librdrm >= 2.4.22 1977 1978 Bug fixes 1979 --------- 1980 * Attempt to fix infinite MI_WAIT_FOR_EVENT while watching video 1981 https://bugs.freedesktop.org/show_bug.cgi?id=28964 1982 1983 [Various new checks have been added to the video code here, but the 1984 bug fix hasn't yet been verified by the original reporter.] 1985 1986 * Fix buffer-object leak 1987 https://bugs.freedesktop.org/show_bug.cgi?id=26946 1988 1989 * Fix memory leak on server reset 1990 1991 * Fix crash due to unchecked pixmap allocation 1992 https://bugs.freedesktop.org/show_bug.cgi?id=29187 1993 1994 * Fix for video artifacts when using dualscreen 1995 https://bugs.freedesktop.org/show_bug.cgi?id=29213 1996 1997 * Fix for incorrect characters in gnome-terminal when using compiz 1998 https://bugs.freedesktop.org/show_bug.cgi?id=28438 1999 2000 * Fix for hanging, full-screen applications, (flash, compiz, etc.) 2001 https://bugs.freedesktop.org/show_bug.cgi?id=29584 2002 2003 * Fix selection of backlight device on multi-GPU systems 2004 https://bugs.freedesktop.org/show_bug.cgi?id=29273 2005 2006 * Fix to avoid crash with extremely large glyphs 2007 https://bugs.freedesktop.org/show_bug.cgi?id=29430 2008 2009 * Fix for eDP panels incorrectly being given only a single, valid mode 2010 https://bugs.freedesktop.org/show_bug.cgi?id=30069 2011 2012 * Fix GPU hang involving clipped SRC copies 2013 https://bugs.freedesktop.org/show_bug.cgi?id=30120 2014 2015 * Fix to compile for 1.6 series X server. 2016 2017 * Fix to retry framebuffer allocation after an initial failure. 2018 2019 * Fix to disable dri2 after fallbacks are forced on. 2020 2021 Snapshot 2.12.902 (2010-09-28) 2022 ============================== 2023 This is the second release candidate in preparation for the upcoming 2024 2.13.0 release. The comes exactly one week after 2.12.902 and includes 2025 only a handful of changes. 2026 2027 One significant change is that the drive now requires libdrm 2.4.22 2028 (or newer), as several people reported compilation failures of 2029 xf86-video-intel 2.12.901 with libdrm 2.4.21. 2030 2031 Other changes include a fix to compile for the 1.6 series X server, a 2032 fix to retry framebuffer allocation after an initial failure, and a 2033 fix to disable dri2 after fallbacks are forced on. 2034 2035 Snapshot 2.12.901 (2010-09-21) 2036 ============================== 2037 This is the first release candidate in preparation for the upcoming 2038 2.13.0 release. We will appreciate any feedback we can get from 2039 testing of this snapshot. 2040 2041 Bugs fixed in this snapshot (compared to 2.12.0) 2042 ------------------------------------------------ 2043 * Attempt to fix infinite MI_WAIT_FOR_EVENT while watching video 2044 https://bugs.freedesktop.org/show_bug.cgi?id=28964 2045 2046 [Various new checks have been added to the video code here, but the 2047 bug fix hasn't yet been verified by the original reporter.] 2048 2049 * Fix buffer-object leak 2050 https://bugs.freedesktop.org/show_bug.cgi?id=26946 2051 2052 * Fix memory leak on server reset 2053 2054 * Fix crash due to unchecked pixmap allocation 2055 https://bugs.freedesktop.org/show_bug.cgi?id=29187 2056 2057 * Fix for video artifacts when using dualscreen 2058 https://bugs.freedesktop.org/show_bug.cgi?id=29213 2059 2060 * Fix for incorrect characters in gnome-terminal when using compiz 2061 https://bugs.freedesktop.org/show_bug.cgi?id=28438 2062 2063 * Fix for hanging, full-screen applications, (flash, compiz, etc.) 2064 https://bugs.freedesktop.org/show_bug.cgi?id=29584 2065 2066 * Fix selection of backlight device on multi-GPU systems 2067 https://bugs.freedesktop.org/show_bug.cgi?id=29273 2068 2069 * Fix to avoid crash with extremely large glyphs 2070 https://bugs.freedesktop.org/show_bug.cgi?id=29430 2071 2072 * Fix for eDP panels incorrectly being given only a single, valid mode 2073 https://bugs.freedesktop.org/show_bug.cgi?id=30069 2074 2075 * Fix GPU hang involving clipped SRC copies 2076 https://bugs.freedesktop.org/show_bug.cgi?id=30120 2077 2078 Release 2.12.0 (2010-06-24) 2079 =========================== 2080 We are pleased to announce this major release of the xf86-video-intel 2081 2D driver. It contains many correctness and performance improvements 2082 compared to the 2.11 releases. We encourage everyone using 2.11 to 2083 upgrade to 2.12. 2084 2085 [This release contains several bug fixes since the earlier 2.11.901 2086 release candidate---see below for details.] 2087 2088 New requirements compared to 2.11 2089 --------------------------------- 2090 * Libdrm >= 2.4.21 2091 2092 Major performance improvements 2093 ------------------------------ 2094 There have been many performance improvements targeting the 2095 915G/945G/Pineview graphics chipsets (thank to Chris Wilson!). Areas 2096 improved include: 2097 2098 * Major improvements to glyph rendering 2099 2100 * Avoid software fallback when using extended desktops, (for example, 2101 video playback) 2102 2103 * Better performance when using large windows, (for example with 2104 firefox scrolling) 2105 2106 * Avoiding migration ping-pong with gigantic drawing 2107 2108 The following speedups (measured with cairo-perf-trace/cairo-traces) 2109 capture some of the improvements.

The rendercheck test suite 2134 passes once again and there has been a significant reduction in the 2135 number of errors detected by the cairo test suite (notably center 2136 sampling and EXTEND_NONE behaviors are fixed). 2137 2138 Other notable bug fixes include: 2139 2140 * Fix for bug 28446 Garbled fonts with Mathematica 2141 https://bugs.freedesktop.org/show_bug.cgi?id=28446 2142 2143 * Fixes for page-flipping and other DRI2-handling bugs, (Thanks Jesse 2144 Barnes, and Kristian Hgsberg) 2145 2146 * Avoid corruption when using extended desktops, (for example, video 2147 playback) 2148 2149 (The bug fixes below are new since the 2.11.901 release candidate) 2150 2151 * Fix corrupted output when screen rotated 2152 https://bugs.freedesktop.org/show_bug.cgi?id=28461 2153 2154 * Fix corrupted rendering in KDE due to missing flush. 2155 2156 * Fixes i830_uxa_put_image for the following issues: 2157 2158 Bug 28569 - [i965] IGN's flash-based video player crashes X 2159 https://bugs.freedesktop.org/show_bug.cgi?id=28569 2160 2161 Bug 28573 - [i965] Fullscreen flash and windowed SDL games fail to 2162 update the screen 2163 https://bugs.freedesktop.org/show_bug.cgi?id=28573 2164 2165 * Fix visual corruption of scrollbar in Chromium 2166 2167 * Fix tiling limits to resolve this issue: 2168 2169 Bug 28497 - Graphics corruption after opening a specific website 2170 https://bugs.freedesktop.org/show_bug.cgi?id=28497 2171 2172 Snapshot 2.11.901 (2010-06-14) 2173 ============================== 2174 This is the first release candidate in preparation for the upcoming 2175 2.12.0 release. We will appreciate any feedback we can get from 2176 testing of this snapshot to improve the 2.12.0 release. 2177 2178 New requirements compared to 2.10 2179 --------------------------------- 2180 * Libdrm >= 2.4.19 2181 2182 Major performance improvements 2183 ------------------------------ 2184 There have been many performance improvements targeting the 2185 915G/945G/Pineview graphics chipsets (thank to Chris Wilson!). Areas 2186 improved include: 2187 2188 * Major improvements to glyph rendering 2189 2190 * Avoid software fallback when using extended desktops, (for example, 2191 video playback) 2192 2193 * Better performance when using large windows, (for example with 2194 firefox scrolling) 2195 2196 * Avoiding migration ping-pong with gigantic drawing 2197 2198 The following speedups (measured with cairo-perf-trace/cairo-traces) 2199 capture some of the improvements. These were measured on a Pineview 2200 system with a very recent X server, (from git just before 1.8.1).

The rendercheck test suite 2225 passes once again and there has been a significant reduction in the 2226 number of errors detected by the cairo test suite (notably center 2227 sampling and EXTEND_NONE behaviors are fixed). 2228 2229 Other notable bug fixes include: 2230 2231 * Fix for bug 28446 Garbled fonts with Mathematica 2232 https://bugs.freedesktop.org/show_bug.cgi?id=28446 2233 2234 * Fixes for page-flipping and other DRI2-handling bugs, (Thanks Jesse 2235 Barnes, and Kristian Hgsberg) 2236 2237 * Avoid corruption when using extended desktops, (for example, video 2238 playback) 2239 2240 Release 2.11.0 (2010-03-29) 2241 =========================== 2242 New in 2.11: DRI2 and page flipping 2243 ----------------------------------- 2244 The most significant new feature of this release is support for new 2245 DRI2 APIs, allowing page flipping to occur for swaps that are 2246 full-screen and not rotated. 2247 2248 Performance improvements in 2.11 compared to 2.10 2249 ------------------------------------------------- 2250 Dramatically improved performance of large pixmaps on 2251 memory-constrained hardware, (such as 945), by using tiling. 2252 Note that this fix is new since the most recent release 2253 candidate for this release (2.10.903). 2254 2255 https://bugs.freedesktop.org/show_bug.cgi?id=25375 2256 2257 Elimination of software fallback with alpha-only pixmap (a fix which 2258 eliminated a full second from the Moblin boot time): 2259 2260 https://bugs.freedesktop.org/show_bug.cgi?id=26189 2261 2262 Notable bug fixes in 2.11 compared to 2.10 2263 ------------------------------------------ 2264 Fix for undesired black borders on some images, (caued several 2265 problems with firefox): 2266 2267 http://bugs.freedesktop.org/show_bug.cgi?id=17933 2268 2269 And other fixes to provide more conformance with existing 2270 software-rendering, (as measures by the cairo test suite), such as the 2271 sampling location for nearest-neighbor sampling. 2272 2273 Other changes 2274 ------------- 2275 Eric Anholt and Daniel Vetter both removed large piles of old and 2276 useless code now that the driver requires kernel modesetting 2277 (KMS). This continues to reduce the mainteance burden of the driver, 2278 making it easier to isolate and fix bugs. 2279 2280 Snapshot 2.10.903 (2010-03-22) 2281 ============================== 2282 Some notable bug fixes 2283 ---------------------- 2284 * Fix unpredictable results in page-flipping code due to access of an 2285 uninitialized variable. 2286 2287 * Two fixes that address a number of long-outstanding failures in the 2288 cairo test suite: 2289 2290 Remove coord-adjust for nearest centre-sampling. 2291 2292 Fill alpha on xrgb images. Closes: 2293 2294 Bug 17933 - x8r8g8b8 doesn't sample alpha=0 outside surface bounds 2295 http://bugs.freedesktop.org/show_bug.cgi?id=17933 2296 2297 * Fix a regression introduced in 2.10.902: 2298 2299 Fatal server error: 2300 i915_emit_composite_setup: ADVANCE_BATCH: 2301 under-used allocation 100/104 2302 2303 Bug 21723 [i915 bisected] rendering makes X crash 2304 http://bugs.freedesktop.org/show_bug.cgi?id=27123 2305 2306 Other minor fixes (avoid trying to print an error message with a freed 2307 string, set a variable to NULL after freeing), and documentation 2308 updates are also included. 2309 2310 Snapshot 2.10.902 (2010-03-15) 2311 ============================== 2312 Some significant bug fixes 2313 -------------------------- 2314 Fix video color problems due to YUV plane ordering issue. This fixed a 2315 regression that showed up recently (only in these release candidates). 2316 2317 Fix recent regression leading to corruption under compiz: 2318 2319 https://bugs.freedesktop.org/show_bug.cgi?id=26814 2320 2321 Further DRI2 improvements/fixes from Mario Kleiner and Jesse Barnes, 2322 (including support for SwapBuffers request with divisor != 0). 2323 2324 Fix build against X server 1.6 branch. 2325 2326 Avoid flooding logs after an error occurs. 2327 2328 And dramatic code cleanups 2329 -------------------------- 2330 Eric Anholt removed several cases of old, useless code, (conditions 2331 that could not occur now that we require KMS, etc.). 2332 2333 Daniel Vetter eliminated piles of code by modernizing the XvMC 2334 memory-management and completely removing the old i830_memory 2335 allocator (i830_allocate_memory, i830_free_memory), etc. 2336 2337 Snapshot 2.10.901 (2010-02-26) 2338 ============================== 2339 The most significant new feature of this release is support for new 2340 DRI2 APIs, allowing page flipping to occur for swaps that are 2341 full-screen and not rotated. 2342 2343 Some significant bug fixes 2344 -------------------------- 2345 * Avoid fallback due to failing to extract pixel value from an 2346 alpha-only solid, (this fix eliminated 1 second from Mobilin boot 2347 time). 2348 2349 https://bugs.freedesktop.org/show_bug.cgi?id=26189 2350 2351 * Handle full-height blits without tearing in CopyRegion 2352 2353 https://bugs.freedesktop.org/show_bug.cgi?id=22475 2354 2355 Several other fixes and cleanups are included as well, (including the 2356 removal of stale utility code that is now maintained in the separate 2357 intel-gpu-tools module). 2358 2359 Release 2.10.0 (2010-01-04) 2360 =========================== 2361 New requirements of 2.10 compared to 2.9 2362 ---------------------------------------- 2363 * Linux kernel with kernel-modesetting (KMS) 2364 2365 All user-modesetting code has now been removed from the driver. 2366 We highly recommend kernel version 2.6.32 or later. 2367 2368 * Libdrm >= 2.4.16 2369 2370 New features in 2.10 compared to 2.9 2371 ------------------------------------ 2372 * New driver debugging options available in xorg.conf 2373 (DebugFlushBatches, DebugFlushCaches, DebugWait). See "man intel" 2374 for more details. 2375 2376 * Video overlay support with KMS. This currently requires Linux 2377 2.6.33, but a backport to 2.6.32 is available here: 2378 2379 http://gitorious.org/daniel-s-linux-stuff/linux-kernel/commits/intel-kms-overlay-for-2.6.32 2380 2381 Notable fixes in 2.10 compared to 2.9 2382 ----------------------------------- 2383 * Fix crash when XRenderComposite is called with a -1 value for 2384 width/height, (crash at login when using compiz). 2385 2386 http://bugs.freedesktop.org/show_bug.cgi?id=24724 2387 2388 * Fix to support larger extended desktops, (such as a 2560x1600 plus a 2389 1920x1200 monitor). 2390 2391 2392 * Fix glyph corruption due to insufficient cache flushing: 2393 2394 https://bugs.freedesktop.org/show_bug.cgi?id=24315 2395 2396 Several other correctness and performance fixes are also included. 2397 2398 Note: The driver code of the 2.10.0 release is identical to that of 2399 the 2.9.99.901 release candidate. The only changes in 2.10.0 compared 2400 to 2.9.99.902 are a minor change to the configure script, and some 2401 small updates to the documentation. 2402 2403 Snapshot 2.9.99.902 (2009-12-10) 2404 ================================ 2405 This is the second release candidate in preparation for the upcoming 2406 2.10.0 release. We will appreciate any feedback we can get from 2407 testing of this snapshot to improve the 2.10.0 release. 2408 2409 Compared to the previous snapshot, this snapshot now correctly 2410 verifies that libdrm 2.4.16 (or newer) is available. The previous 2411 snapshot also required libdrm 2.4.16 for correct functionality, but 2412 neglected to notify the user of this at configure, compile, or install 2413 time and would instead simply fail to run. 2414 2415 Snapshot 2.9.99.901 (2009-11-30) 2416 ================================ 2417 This is the first release candidate in preparation for the upcoming 2418 2.10.0 release. We will appreciate any feedback we can get from 2419 testing of this snapshot to improve the 2.10.0 release. 2420 2421 With this snapshot, the xf86-video-intel driver requires kernel 2422 modesetting (KMS) as all of the user modesetting (UMS) support has 2423 been removed from the driver. 2424 2425 Release 2.9.0 (2009-09-28) 2426 ========================== 2427 We are pleased to announce the 2.9.0 release of the xf86-video-intel 2428 driver. (If you have been following along at home, this release is 2429 identical to the 2.8.99.902 release candidate other than the version 2430 number). 2431 2432 New features in 2.9 compared to 2.8 2433 ----------------------------------- 2434 * Support for the B43 chipset. 2435 2436 Major fixes in 2.9.0 compared to 2.8.0 2437 -------------------------------------- 2438 * Multiple fixes to make the driver stable for 8xx chipsets, (855GM, 2439 865G, etc.). The 2.8 driver series was extremely unstable with many 2440 of these chipsets. 2441 2442 https://bugs.freedesktop.org/show_bug.cgi?id=22904 (and many duplicates) 2443 https://bugs.freedesktop.org/show_bug.cgi?id=22947 2444 2445 * Add support for BACKLIGHT property when using kernel modesetting 2446 (KMS). This allows backlight adjustment with programs such as 2447 "xbacklight -set <percentage>" or "xrandr --set BACKLIGHT <value>". 2448 2449 https://bugs.freedesktop.org/show_bug.cgi?id=20963 2450 2451 * Fix so that "xrandr --scale" works when using KMS. 2452 2453 https://bugs.freedesktop.org/show_bug.cgi?id=22893 2454 2455 * Fix segfaults of X server when logging out. 2456 2457 https://bugs.freedesktop.org/show_bug.cgi?id=20516 2458 2459 * Avoid falling back to software for 1-bit alpha-only masks. 2460 2461 https://bugs.freedesktop.org/show_bug.cgi?id=23184 2462 2463 * Fix pixel sampling position for 8xx chipsets, (fixes some cairo-test 2464 suite failures). 2465 2466 Snapshot 2.8.99.901 (2009-09-09) 2467 ================================ 2468 This is the first release candidate in preparation for the upcoming 2469 2.9.0 release. We will appreciate any feedback we can get from testing 2470 of this snapshot to improve the 2.9.0 release. 2471 2472 See the commit log for changes in this release, and developers, please 2473 provide me summaries for any major features in this release that you 2474 think should appear in NEWS and in the 2.9.0 release notes. 2475 2476 Note: We are still investigating failures with 865G chipsets, (these 2477 failures existed in the 2.8 series as well). We are hoping to fix 2478 these failures before the 2.9.0 release. 2479 2480 Release 2.8.0 (2009-07-20) 2481 ========================== 2482 We are pleased to present this major release of the xf86-video-intel 2483 driver. This release is very similar to the 2.7.99.902 release 2484 candidate but includes a couple of additional bug fixes, (for bugs 2485 #22760 and @22483). 2486 2487 Compared to the 2.7 releases this driver contains several new features 2488 and many bug fixes. The driver now depends on X server 1.6 or later, 2489 and eliminates several obsolete code paths, (XAA and EXA removed in 2490 favor of UXA, DRI1 support eliminated). The driver certainly will work 2491 best with an i915 module from a recent kernel (2.6.31) and with 2492 kernel-modesetting (KMS, specified by loading i915 with the option 2493 "modeset=1"). 2494 2495 New features in 2.8.0 compared to 2.7 2496 ------------------------------------- 2497 * Remove XAA/EXA/DRI1 and NoAccel, and only support UXA/DRI2 now 2498 (requiring xserver 1.6). 2499 2500 * VLD support added into XvMC for Mpeg2, which decreases CPU usage 2501 when playing video. 2502 2503 Major fixes in 2.8.0 compared to 2.7 2504 ------------------------------------ 2505 * Fix broken front-buffer rendering 2506 https://bugs.freedesktop.org/show_bug.cgi?id=19174 2507 2508 * Fix disabling of XvMC disabled 2509 https://bugs.freedesktop.org/show_bug.cgi?id=20790 2510 2511 * Fix broken VT switch on some machines 2512 https://bugs.freedesktop.org/show_bug.cgi?id=19578 2513 2514 * Improve performance of trapezoid rendering for UXA 2515 https://bugs.freedesktop.org/show_bug.cgi?id=21376 2516 2517 * Vblank sync'd GL buffer swap (fixing video tearing under composite) 2518 https://bugs.freedesktop.org/show_bug.cgi?id=20664 2519 2520 * Fix G41 DRM support 2521 https://bugs.freedesktop.org/show_bug.cgi?id=21095 2522 2523 * Fix crash on some 8xx 2524 https://bugs.freedesktop.org/show_bug.cgi?id=18974 2525 2526 Various fixes for GPU hangs, and more... 2527 2528 Snapshot 2.7.99.902 (2009-07-13) 2529 -------------------------------- 2530 This is the first release candidate in preparation for the upcoming 2531 2.8.0 release. Most major and critical bugs should be fixed, but some 2532 minor bugs may still be present. We will appreciate any feedback we 2533 can get from testing of this snapshot to improve the 2.8.0 release. 2534 2535 Snapshot 2.7.99.901 (2009-06-10) 2536 -------------------------------- 2537 This is the first release candidate in preparation for the upcoming 2538 2.8.0 release. Most critical bugs should be fixed, but some major 2539 bugs may still be present. We will appreciate any feedback we can 2540 get from testing of this snapshot to improve the 2.8.0 release. 2541 2542 Some of the major fixes in this snapshot include: 2543 2544 * Several fixes for intermittent GPU hangs/crashes, (some of 2545 which already appeared in the 2.7.1 release) 2546 2547 * Fix to avoid X crash when viewing large images in browser 2548 2549 * Fix X server failure when running old (non-GEM) kernel 2550 2551 * Fixes for SDVO LVDS mode detection 2552 2553 * Fix major performance regression of trapezoid rendering 2554 compared to XAA/EXA 2555 2556 * New support for tear-free video when using KMS 2557 2558 * New support for tear-free DRI2 CopyRegion 2559 2560 Snapshot 2.7.99.1 (2009-04-28) 2561 ------------------------------ 2562 This is a development snapshot very early in the process toward 2563 developing 2.8. There have been some big changes to the code, and 2564 we're anxious to get feedback on these changes as early as possible. 2565 2566 Here is a summary of the biggest changes: 2567 2568 * Driver now depends on X server 1.6 or later 2569 2570 * Eliminate XAA and EXA support (in favor of UXA) 2571 2572 * Eliminate DRI1 support 2573 2574 * Fixes for running without DRI at all 2575 2576 These code removals represent a deletion of a substantial amount of 2577 code, (and hopefully piles of bugs), as well as reduce the maintenance 2578 effort going forward as the number of combinatorial configurations for 2579 the driver are greatly reduced. This means that users are much more 2580 likely to be running code that has actually been tested, and it will 2581 be much easy for developers to replicate bugs that users experience. 2582 2583 One of the things that would be most useful in testing this release is 2584 to revisit any outstanding bugs that you have previously reported. If 2585 the buggy behavior is gone, (or the bug is no longer relevant---such 2586 as a bug that's specific to XAA only), please feel free to indicate so 2587 in bugzilla or even just close the bug. 2588 2589 If you confirm that the bug is still present, please indicate so in 2590 the bug report. (I was going to ask that you select a 1.7.99 version, 2591 but it looks like bugzilla only has versions for products not 2592 compoenents, while we use a "xorg" product and a "driver/intel" 2593 component.) We definitely want to make any such confirmed bugs a 2594 priority, so it would be nice to have a consistent mechanism to search 2595 for these bugs. Suggestions are welcome on the best approach. 2596 2597 Thanks in advance for any testing or feedback on this snapshot. 2598 2599 Release 2.7.0 (2009-04-15) 2600 -------------------------- 2601 Compared to the 2.6 series, 2.7.0 has a large number of bug fixes, but 2602 also a few significant features, such as: 2603 2604 SDVO-TV support, available on ADD2 card (bug#9992) and 2605 D945GCLF2 board (bug#17776). 2606 2607 Basic SDVO-LVDS support 2608 2609 XV video display without tearing 2610 [Though this isn't working for all users yet, see 2611 https://bugs.freedesktop.org/show_bug.cgi?id=21076 ] 2612 2613 Various fixes for UXA, DRI2, and Kernel modesetting. 2614 2615 We encourage users to use kernel modesetting and UXA acceleration with 2616 this release, which should give the best performance and 2617 robustness. When KMS is available, UXA is the default acceleration 2618 used by the driver, (EXA is the default otherwise). 2619 2620 Known issue: 2621 2622 Some Linux kernel versions (such as 2.6.29) are known to have 2623 broken PAT code that causes recent versions of this driver to 2624 fail, (which can manifest as the X server simply not 2625 starting). This can be verified by adding the "nopat" option 2626 to the kernel command-line and seeing the failure go away. We 2627 hope that newer kernels in the 2.6.29.x as well as 2.6.30 and 2628 above will have working PAT code. 2629 2630 Some of the most notable bugs fixed in 2.7.0 include: 2631 2632 [GM45 965GM] bad htotal causes panel startup failure 2633 https://bugs.freedesktop.org/show_bug.cgi?id=17292 2634 2635 [xrandr TV] need TV output property control 2636 https://bugs.freedesktop.org/show_bug.cgi?id=12763 2637 2638 [TV] "xrandr --set TV_FORMAT" gets BadMatch error 2639 https://bugs.freedesktop.org/show_bug.cgi?id=16566 2640 2641 [945 tiling] Low performance due to no A17 workaround 2642 https://bugs.freedesktop.org/show_bug.cgi?id=16835 2643 2644 [TV]Flicker when launching applications in the 2.4-branch 2645 https://bugs.freedesktop.org/show_bug.cgi?id=17405 2646 2647 [945GM FBC] FBC causes underruns & flicker 2648 https://bugs.freedesktop.org/show_bug.cgi?id=18651 2649 2650 [xv] Textured video suffers from tearing 2651 https://bugs.freedesktop.org/show_bug.cgi?id=19635 2652 2653 [G45] Random hangs with UXA 2654 https://bugs.freedesktop.org/show_bug.cgi?id=19734 2655 2656 [945GM] Any 3D app is slow in resolution higher than 800x600 2657 with UXA+DRI2, due to tiling 2658 https://bugs.freedesktop.org/show_bug.cgi?id=19738 2659 2660 [i915 UXA,EXA] rotation messes display with tiling on 2661 https://bugs.freedesktop.org/show_bug.cgi?id=20265 2662 2663 [G45] DRI2/UXA gives solid white instead of transparency 2664 https://bugs.freedesktop.org/show_bug.cgi?id=20321 2665 2666 LVDS output not detected 2667 https://bugs.freedesktop.org/show_bug.cgi?id=20517 2668 2669 xf86-video-intel-2.6.3: Xv crashes X server 2670 https://bugs.freedesktop.org/show_bug.cgi?id=20525 2671 2672 [G965 non-GEM] systray in KDE 4 completely broken 2673 https://bugs.freedesktop.org/show_bug.cgi?id=20527 2674 2675 [SDVO-TV]the desktop is teared in four sections on the screen 2676 https://bugs.freedesktop.org/show_bug.cgi?id=20550 2677 2678 Intel video driver 2.6.3 crashes with XVideo 2679 https://bugs.freedesktop.org/show_bug.cgi?id=20563 2680 2681 [855GM] Xv crash with non-KMS 2682 https://bugs.freedesktop.org/show_bug.cgi?id=20585 2683 2684 2.6.99.902 breaks native 1680x1050 mode on TMDS -- EDID miss 2685 https://bugs.freedesktop.org/show_bug.cgi?id=20594 2686 2687 [945GM TV] 2.6.99.902 sets a too high CONTRAST-value 2688 https://bugs.freedesktop.org/show_bug.cgi?id=20670 2689 2690 [915GM] fail to detect LVDS with new VBT code 2691 https://bugs.freedesktop.org/show_bug.cgi?id=20752 2692 2693 [regression i965]tiled output when start X 2694 https://bugs.freedesktop.org/show_bug.cgi?id=20803 2695 2696 2.6.99.902: LVDS wrongly detected as disconnected 2697 https://bugs.freedesktop.org/show_bug.cgi?id=20826 2698 2699 vt switching fails and crashes X 2700 https://bugs.freedesktop.org/show_bug.cgi?id=20863 2701 2702 [HDMI] The screen will flicker when some application runs on 2703 G45-64 2704 https://bugs.freedesktop.org/show_bug.cgi?id=20875 2705 2706 TexturedVideo is offsetted wrongly on dualhead 2707 https://bugs.freedesktop.org/show_bug.cgi?id=20980 2708 2709 [EXA] xvideo hang X 2710 https://bugs.freedesktop.org/show_bug.cgi?id=21027 2711 2712 [EXA] x11perf performance regression 2713 https://bugs.freedesktop.org/show_bug.cgi?id=21029 2714 2715 And many others... 2716
