NEWS revision 1.1.1.2
1 Release 2.21.15 (2013-08-21) 2 ============================ 3 Some build fixes for the BSDs and alternate compiler, and conflicting 4 configure options and a critcial fix for some PRIME setups. 5 6 * Don't fail to configure if DRI1 is not available and the user asks 7 for both DRI and KMS-only 8 [Regression from 2.21.14] 9 10 * Lots of miscellaneous fixes for older gcc, other compilers and BSD. 11 12 * Initial framework support for hosted X. 13 14 * Improve transition from fbcon to X with multiple outputs and extended 15 desktops. 16 17 * Ensure the framebuffer exists before checking it against the CRTC 18 constraints. 19 https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/121234 20 [Regression from 2.21.10] 21 22 * Add RGB overlay support for Ironlake and later. 23 24 * Don't release the overlay buffer too early, i.e. before the client 25 disables the Xv image. 26 27 * Tweak the ring switching logic to reduce use of semaphores on 28 Sandybridge and later - a delicate balancing act between trying to 29 use the faster engine for the task and preventing concurrent use of 30 multiple rings. 31 32 33 Release 2.21.14 (2013-08-04) 34 ============================ 35 A few updates for the top-end Haswell systems (notably GT3 and GT3e 36 systems), in particular, setting the appropriate thread counts for the 37 larger GPU and handling a few scaling issues with the emedded DRAM. More 38 important than the performance tuning though is a fix for a critical 39 issue encountered by a few people on gen4/gen5 systems. 40 41 * Initial performance tuning for HSW:GT3e 42 43 * Fix a crash with Planetary Annihilation 44 45 * Disable triple buffering for compositors 46 47 * Reserve space in the exec buffer array for deferred VBOs. 48 https://bugs.freedesktop.org/show_bug.cgi?id=67504 49 50 51 Release 2.21.13 (2013-07-27) 52 ============================ 53 A minor release to repair the build for non-Linux systems, and to undo a 54 few more regressions. 55 56 * Avoid potential memory corruption with allocations of very small 57 depth 1 bitmaps. 58 59 * Fix source clipping whilst computing copy extents and exposures. 60 [Regression from 2.21.12] 61 https://bugs.freedesktop.org/show_bug.cgi?id=66970 62 63 * Use /proc/cpuinfo if cpuid4 is not available (old hardware or old 64 gcc), and repair the build on systems without cpuid. 65 [Regression from 2.21.12] 66 67 * Fix performance regression on Ironlake from inadvertently flushing 68 after every operation. 69 [Regression from 2.21.11] 70 https://bugs.freedesktop.org/show_bug.cgi?id=67157 71 72 * Fix conflict handling when probing initial KMS configuration for 73 ZaphodHeads. 74 [Regression from 2.21.11] 75 https://bugs.freedesktop.org/show_bug.cgi?id=67176 76 77 * Stop being overly restrictive and rejecting stale DRI2 buffers. 78 (DRI2 is inherently racy in that the client may have completed and 79 submitted rendering to buffers that are now invalid on the server. 80 This race is magnified by bugs within the Xserver where it forgets 81 to notify the DRI2 clients of certain invalidation events.) 82 https://bugs.freedesktop.org/show_bug.cgi?id=67210 83 84 * Handle a failure to use a GTT mmap for a pixmap upload and try 85 an alternative method before giving up. 86 87 88 Release 2.21.12 (2013-07-14) 89 ============================ 90 In this release, we clear up the teething troubles from preserving the KMS 91 configuration, notably external connections on Haswell and plugging in new 92 outputs after startup were broken. Besides these regression fixes, there 93 are a couple of fixes for some long standing issues, such as incorrect 94 rendering on gen2, an infinite loop with very, very large pixmaps and a 95 slight improvement to the tempermental gen4. 96 97 * Allow untiled scanouts again (required for large extended desktops on 98 gen2 and gen3). 99 [Regression from 2.21.11] 100 101 * Use the correct count of the number of dirty damage boxes for the quick 102 check on whether the existing damage contains the requested area. 103 The danger is that we may get a false result and skip migration and so 104 cause pixmap corruption (in the unlikely event that the application 105 frequently causes fallbacks). 106 [Regression from 2.21.11] 107 https://bugs.freedesktop.org/show_bug.cgi?id=66430 108 109 * Fix initial connection probing for multi-function encoders, such as the 110 external connections on Haswell. 111 [Regression from 2.21.11, initial connection probing] 112 https://bugs.freedesktop.org/show_bug.cgi?id=66488 113 114 * Fix gen2 rendercopy into a8 surfaces, for example, glyph uploads into 115 the glyph cache. 116 117 * Fix detection of user overrides for initial connection configuration. 118 The code used the xorg-server-1.15 values, having missed the 119 introduction of ZoomModes into that release. 120 [Regression from 2.21.11, initial connection probing] 121 122 * Always initialise the gamma ramp, even on unconnected CRTCs. 123 https://bugs.freedesktop.org/show_bug.cgi?id=66563 124 [Regression from 2.21.11, initial connection probing] 125 126 * Some more tuning of the gen4 vertex corruption workaround. The root 127 cause behind the GPU using incorrect texture coordinates is still 128 not solved, but by reducing the maximum number or rectangles in 129 flight through the GPU we reduce the likelihood of corruption. 130 131 * Fix compilation with gcc-4.5 132 [Regression from 2.21.11] 133 134 * Avoid integer overflow when performing tiled uploads and operations 135 on very large (>28k pixels wide or tall pixmaps) 136 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1200766 137 138 139 Release 2.21.11 (2013-06-30) 140 ============================ 141 An eventful week. What started with a regression with some builds of 142 firefox on some machines lead ultimately to the discovery of an older 143 kernel bug. Aside from the work to fix the image bug and a few other 144 older bugs that were reported and resolved this week, there is also a 145 (hopefully) subtle change to the initial configuration of displays. In 146 the absence of user overrides in xorg.conf, the DDX will try to preserve 147 the same display configuration as used by the kernel, which hopefully 148 will be the same configuration as setup by the BIOS. The result should 149 be a boot sequence that does not resize at all (aka fastboot) - until 150 the display manager takes over and loads a completely different 151 configuration! 152 153 * Add reference counting of drmMaster for ZaphodHeads 154 https://bugs.freedesktop.org/show_bug.cgi?id=66041 155 156 * Add a GPU flush before changing blend modes on Ironlake 157 https://bugs.freedesktop.org/show_bug.cgi?id=51422 158 159 * Fix occasional missing images for inplace uploads 160 [regression from 2.21.10] 161 https://bugs.freedesktop.org/show_bug.cgi?id=66059 162 163 * Add missing utility files to the tarball and remove a few unused ones 164 165 * Initialise PolyPoint operand state before calling miWideDash 166 https://bugs.freedesktop.org/show_bug.cgi?id=66104 167 168 * Fix redirection handling for rendering into large surfaces 169 https://bugs.freedesktop.org/show_bug.cgi?id=66168 170 https://bugs.freedesktop.org/show_bug.cgi?id=66249 171 172 * Fix compilation of UXA with xorg-xserver < 1.10 173 [regression from 2.20.0] 174 175 * Fix consideration of gradients for deciding when to migrate render 176 operations 177 [performance regression from 2.21.10, the bug itself is older] 178 https://bugs.freedesktop.org/show_bug.cgi?id=66297 179 180 Also fixed this week was: 181 182 commit 22fd5ca947b58901927d100d2b1aa0f1672b3435 183 Author: Chris Wilson <chris (a] chris-wilson.co.uk> 184 Date: Fri Jun 28 16:54:08 2013 +0100 185 186 drm/i915: Only clear write-domains after a successful wait-seqno 187 188 which affects kernels 3.7 - 3.10, coming to a stable kernel near you soon. 189 190 191 Release 2.21.10 (2013-06-22) 192 ============================ 193 Fixes missing support for Xv (with the textured video adaptor) on 194 Haswell, and an old bug with wide monitors on various generation. Along 195 with a few other regression fixes and performance tweaks for various 196 corner cases. 197 198 * Do not lose track of fast pageflips across mode changes 199 [regression from 2.20.8] 200 201 * Fix listing of Visuals for Xv 202 [regression from 2.21.8] 203 https://bugs.freedesktop.org/show_bug.cgi?id=65479 204 205 * Improve coherency of concurrent CPU accesses to a pixmap 206 https://bugs.freedesktop.org/show_bug.cgi?id=61628 207 208 * Set sampler swizzling for textured video on Haswell 209 https://bugs.freedesktop.org/show_bug.cgi?id=65699 210 211 * Apply scanout stride limits 212 https://bugs.freedesktop.org/show_bug.cgi?id=65099 213 214 * Undo the self-copy for cloned pixmaps for loimpress's animations 215 [regression from 2.21.7] 216 https://bugs.freedesktop.org/show_bug.cgi?id=65665 217 218 219 Release 2.21.9 (2013-06-06) 220 =========================== 221 Consolidating the copy-on-write support, hopefully cleaning up the last of 222 the regressions. 223 224 * Restore vsync on textured videos. 225 [regression from 2.21.8] 226 https://bugs.freedesktop.org/show_bug.cgi?id=65048 227 228 * Fix incorrect ordering of possible_clones with certain outputs, which 229 can lead to attempting to incorrectly clone 2 outputs and failing to 230 light them up. 231 [regression from 2.20.10] 232 233 * Fix performance regression from not promoting large fills to the GPU 234 [regression from 2.21.7] 235 236 * Undo the pixmap clone before performing a DRI2CopyRegion 237 [regression from 2.21.7] 238 https://bugs.freedesktop.org/show_bug.cgi?id=65250 239 240 241 Release 2.21.8 (2013-05-27) 242 =========================== 243 A quick release to cleanup a few regressions from the introduction of 244 copy-on-write support, notably hitting wine applications and a memory 245 leak for firefox. 246 247 * Only mark a PolyFillRect operation as replacing if it is unclipped 248 https://bugs.freedesktop.org/show_bug.cgi?id=64841 249 250 * Prevent potential NULL dereference of damage when checking COW support 251 252 * Fix invalidation of clone after dirtying the pixmap via the CPU 253 254 * Prevent discarding an operation before requiring it for a fallback 255 256 * Fix memory leak from replacing the clone under certain circumstances 257 https://bugs.freedesktop.org/show_bug.cgi?id=64978 258 259 260 Release 2.21.7 (2013-05-21) 261 =========================== 262 A couple of weeks turned into a month and a couple of weeks... Amidst 263 the usual bug fixes, we have added the complete set of Haswell PCI IDs - 264 hopefully future proofing ourselves against being surprised by new 265 products. We can also now use the correct term for the top of the range 266 Haswell variants, GT3. 267 268 * Fix several assertion failures hit by Jiri Slaby. 269 270 * Allow XvMC to also target overlay/sprite planes. 271 272 * Throw in a paranoid MI_FLUSH between BLT and RENDER operations on 273 Ironlake. 274 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1168066 275 276 * Prevent reuse of old framebuffers after a resize. 277 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1157678 278 279 * Fix compilation with --enable-valgrind and no --enable-debug 280 281 * Improve partial migration of render sources. 282 283 * Fix origin of trapezoids. 284 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1178020 285 286 * Introduce copy-on-write support for cloning pixmaps. The ultimate 287 goal here is to efficiently support the TearFree mode of operation, 288 but this provides immediate benefits with firefox - most importantly 289 because of the inefficient way it now implements scrolling. 290 291 292 Release 2.21.6 (2013-04-06) 293 =========================== 294 A surprising highlight of this release is a little refresh to the KMS 295 support for OpenBSD. OpenBSD now has its own KMS implementation which is 296 mostly compatible with the interface in Linux, with one or two tweaks 297 supplied by Mark Kettenis. This release continues to cleanup behaviour 298 for Haswell. 299 300 * Workaround a failure by the xserver to invalidate DRI buffers 301 following a pixmap change for XComposite redirection. 302 https://bugs.freedesktop.org/show_bug.cgi?id=62614 303 304 * Fix computation of clip extents for stippling 305 https://bugs.freedesktop.org/show_bug.cgi?id=62618 306 307 * Support KMS on OpenBSD, by Mark Kettenis 308 309 * Clean up sockets upon CloseScreen (making ourselves better behaved 310 for muxed setups). 311 312 * Fix the tests for AVX/AVX2 support in CPUID and remember to check for 313 OS support as well. 314 315 * Report a monotonic UST value for undisplayed drawables rather than 0 316 by Daniel Kurtz 317 318 * Fix video playback on gen4 through a complex clip (more gen4 GPU woes) 319 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1162046 320 321 322 Release 2.21.5 (2013-03-21) 323 =========================== 324 Haswell reintroduces a command to load the scanline window from the 325 command stream and so requires its own specialised wait-for-vsync routine 326 - failure to do so was then causing hangs when trying to do tearfree video 327 or use a compositor. 328 329 * Prevent buffer leak if a non-fullscreen Window is closed with multiple 330 pending swap events. 331 332 * Fix offset transformation for fallback gradient paths. 333 https://bugs.freedesktop.org/show_bug.cgi?id=62198 334 335 * Prevent Glamor from crashing if misconfigured. 336 Thanks to Michel Dnzer. 337 338 * Prevent UXA from crashing if torn down during PreInit. 339 Thanks to Aaron Plattner. 340 341 * Prevent miscompilation with different functional units having different 342 compiler flags. Some functions were expected to be inlined and so 343 recompiled with the current target. However, some compilers were 344 choosing to emit subroutine calls instead without noticing that the 345 ABI was different between the caller and callee - causing corruption. 346 https://bugs.freedesktop.org/show_bug.cgi?id=62198 347 348 * Fix rendering of CompositeTriFan with recent Xorg. 349 350 * Apply the video src-offset fix highlighted in the last release! 351 A typo prevented the fix from working for gen4+. 352 https://bugs.freedesktop.org/show_bug.cgi?id=62343 353 354 * Fix rendering of multiple glyphs to very large destination surfaces 355 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1156387 356 357 * Fix scanline waits for Haswell 358 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1156679 359 360 361 Release 2.21.4 (2013-03-11) 362 =========================== 363 More bugs, more fixes, more releases. A minor new feature being introduced 364 is the runtime detection of CPU instructions sets along with specialised 365 paths to take advantage of the available CPU. 366 367 * Honour LinearFramebuffer for clumsy PowerXpress integration 368 369 * Disable read-read optimisations of mappings whilst the root 370 cause of a corruption issue remains elusive. 371 https://bugs.freedesktop.org/show_bug.cgi?id=61628 372 373 * Disable 8-bpp framebuffers in UXA as the regressions therein 374 remain unfixed. 375 376 * Restart vertex checks after lock contention 377 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1124576 378 379 * Handle Screen Pixmap recreation whilst exported via PRIME. 380 381 * Correct application of scale factors to video source offsets. 382 https://bugs.freedesktop.org/show_bug.cgi?id=61610 383 384 * Chain up CloseScreen so that resources are actually freed across regen 385 https://bugs.freedesktop.org/show_bug.cgi?id=56608 386 387 * Fix Haswell CRW PCI-IDs 388 389 * Handle batch submission failure during DRI copies 390 https://bugs.freedesktop.org/show_bug.cgi?id=61708 391 392 * Probe for kernel support of requested Screen depth 393 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1135403 394 395 * Correct GPU limits for early gen2 and gen3 architectures and prevent 396 an infinite recursion for particular image sizes. 397 398 399 Release 2.21.3 (2013-02-20) 400 =========================== 401 A few minor bugfixes, another point release. 402 403 * Fix tracking of DRI pixmaps and their backing bo across reparenting. If 404 we tried to execute a SwapBuffers after a Window was reparented, but 405 before the DRI client has updated its references, then we would end up 406 manipulating an exported pixmap without a flush flag set. In the worst 407 case, this would culminate in a segfault in the driver. 408 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1127497 409 410 * Restore the gen4 workarounds for flickering rendering - a few cases still 411 remain, as the root cause persists. 412 https://bugs.freedesktop.org/show_bug.cgi?id=60402 413 414 * Double check that the device has KMS enabled before claiming. This allows 415 X to gracefully fallback to VESA/fbdev rather than bailing out. 416 https://bugs.freedesktop.org/show_bug.cgi?id=60987 417 418 * Fix the UXA render programs for projective transforms on Ivybridge. 419 420 421 Release 2.21.2 (2013-02-10) 422 =========================== 423 Pass the brown paper bags, I need half a dozen or so. That seemingly 424 innocuous build fix with xorg-1.13 happened to have the little side-effect 425 of breaking glyph rendering with xorg-1.12 and older on 64-bit machines. 426 427 428 Release 2.21.1 (2013-02-10) 429 =========================== 430 A fix for a potential GPU hang on 945gm (GMA950) and earlier chipsets, 431 along with backporting SNA to the packages found in stable distributions 432 like Debian 6.0 (Squeeze). 433 434 * Cleanup compilation warnings from deblint, thanks to Paul Menzel 435 436 * Minor build improvements by Damien Lespiau. 437 438 * Disable generating span geometry for non-rectilinear spans on gen4 439 in order to work around and prevent one class of render corruption. 440 441 * Prevent cache thrashing and severe performance degradation on LLC 442 machines for streaming texture updates. However, note the effect was 443 only observed on just one particular laptop. 444 445 * Fix alignment of subsurface proxies for old chipsets. 446 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1120108 447 448 * Repair build against Xserver-1.6 and contemporary packages. 449 450 451 Release 2.21.0 (2013-02-01) 452 =========================== 453 A few new features: 454 455 * Enable render acceleration for Haswell GT1/GT2. 456 457 * Enable multi-threaded rasterisation of trapezoids and fallback composition 458 459 * Utilise a new kernel interface (v3.9) for processing relocations 460 461 along with a few older features from the 2.20.x series: 462 463 * PRIME support for hotplug GPUs and hybrid systems 464 465 * Support for IvyBridge GT1 machines, aka HD2500 graphics. 466 467 * Stable 830gm/845g support, at last! 468 469 As usual we have a large number of bug fixes since the last release: 470 471 * Prevent a stray relocation being left after a buffer is removed from 472 a batch, leading to GPU hangs. 473 474 * Make the driver more robust against its own failures to submit batches 475 by falling back to software rendering. 476 477 * Fix emission of scanline waits for secondary pipes on gen6/7. Otherwise 478 you may encounter GPU hangs in MI_WAIT_FOR_EVENT. 479 480 * Fix a missing corner pixel when drawing rectangles with PolyLines 481 https://bugs.freedesktop.org/show_bug.cgi?id=55484 482 483 * Don't try to use Y-tiling colour buffers with mesa/i915c as mesa 484 doesn't support them and wil fallback to software rendering 485 486 * Ensure that any cached mmaps are invalidated for a SwapBuffers 487 https://bugs.freedesktop.org/show_bug.cgi?id=60042 488 489 * Correctly handle the composition of rotated displays too large for the 490 3D pipeline 491 https://bugs.freedesktop.org/show_bug.cgi?id=60124 492 493 * Fix the computation of the planar video frame size 494 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1104180 495 496 497 Release 2.20.19 (2013-01-20) 498 ============================ 499 A quick release as the last broke USB DisplayLink slave outputs badly. The 500 performance of those displays was unusable due to an inadvertent change that 501 caused us to flush the entire scanout over the USB for every drawing 502 operation. 503 504 * Implement the GNOME Build API. A couple of minor changes to make 505 integrators and distributors lives a little easier, or at least more 506 consistent. 507 508 * Correctly offset inplace trapezoids for subwindows, such as the GTK+ 509 close button after it has a background image uploaded. 510 511 * Explicitly prevent ring-switching for synchronized rendering to 512 scanouts (for vsync). 513 514 * Clip dirty region to slave pixmaps (otherwise UDL is nigh unusuable) 515 https://bugs.freedesktop.org/show_bug.cgi?id=59539 516 517 518 Release 2.20.18 (2013-01-16) 519 ============================ 520 A bunch of miscellaneous fixes for assertion failures and various 521 performance regressions when mixing new methods for offloads, along with 522 a couple of improvements for rendering with gen4. 523 524 * Remove use of packed unnormalized texture coordinates on gen4/5 as 525 these GPUs do not support unnormalized coordinates in the sampler. 526 527 * Remove dependency upon x86 asm for cross-building to unsupported 528 architectures. 529 https://bugs.gentoo.org/show_bug.cgi?id=448570 530 531 * Apply damage around PRIME updates in the correct order. 532 533 * Correctly read the initial backlight level for when the user 534 overrides UXA's choice of backlight controller. 535 536 * Throttle UXA and prevent it queuing work much faster than the GPU can 537 complete it. This realised itself in impossible performance figures and 538 the entire display freezing for several seconds whlist the GPU caught 539 up. One side effect is that it also caused the DDX to consume more 540 memory than was required as it could not recycle buffers quick 541 enough, and in some cases this produces a marked improvement in 542 performance. Also note on gen2/3 this requires a new libdrm [2.4.41] 543 in order to prevent a bug causing the DDX to fallback to swrast. 544 545 Release 2.20.17 (2012-12-26) 546 ============================ 547 A minor update to prepare for co-operating with the kernel over managing 548 stability on 830gm/845g. On this pair of chipsets, the kernel will perform 549 an extra copy of the batchbuffer into reserved memory, which prevents them 550 from randomly dying. However, that extra copy does have a noticeable 551 impact upon throughput, so we also have a mechanism for userspace to 552 opt-out of the kernel workaround and take responsibility for ensuring its 553 batches are coherent. 554 555 * Build fixes against xorg-1.14 556 https://bugs.freedesktop.org/show_bug.cgi?id=58552 557 https://bugs.freedesktop.org/show_bug.cgi?id=58406 558 559 * Fixed the origin of cropped (textured) video windows (Xv and XvMC) 560 https://bugs.freedesktop.org/show_bug.cgi?id=23033 561 562 * Fix potential corruption when using images larger than ~1GiB 563 564 565 Release 2.20.16 (2012-12-15) 566 ============================ 567 Rejoice! We have found a trick to make 830gm/845g stable at long last. 568 Ever since the switch to GEM and dynamic video memory, those early 569 second generation chipsets have been plagued by instability. The lack of 570 flushing cachelines from the CPU to GMCH was eventually solved by using 571 an undocmented bit, but 830/845 were still hanging under memory pressure. 572 These deaths were all due to garbage finding its way into the command 573 streamer, and they go away if we take a leaf out of the original driver 574 and never reuse those pages for anything else. So for the first time 575 ever, I have been able to complete running the test suite on an 845g, 576 even whilst thrashing the page and buffer caches! 577 578 * Run the SF stage as single-threaded on gen4 to workaround a few issues 579 https://bugs.freedesktop.org/show_bug.cgi?id=57410 580 581 * Keep the scanout SURFACE_STATE separate to avoid overriding its 582 memory access control on gen6/7 (i.e. writes to the scanout need to 583 be kept out of the render cache) 584 585 * Tune batch flushing after an operation to an exported surface under a 586 compositor. 587 588 * Make sure the source is on the CPU for inplace composition of trapezoids 589 using the CPU 590 https://bugs.freedesktop.org/show_bug.cgi?id=56825 591 592 * Immediately flush in the block hander after a split batch to reduce 593 latency between the two halves of an operation. 594 https://bugs.freedesktop.org/show_bug.cgi?id=51718 595 596 * Install a fallback config if we fail to install the desired config 597 at VT switch (i.e. booting, after resume with 3 incompatible pipes on 598 Ivybridge) 599 600 * Pin batches to avoid CS incoherence on 830/845 601 https://bugs.freedesktop.org/show_bug.cgi?id=26345 602 603 604 Release 2.20.15 (2012-12-03) 605 ============================ 606 And lo, enabling more of the common acceleration paths for gen4 revealed 607 another lurking bug - something is wrong with how we prepare Y-tiling 608 surfaces for rendering. For the time being, we can surreptiously disable 609 them for gen4 and avoid hitting GPU hangs. 610 611 * Avoid clobbering the render state after failing to convert the 612 operation to use the blitter. 613 https://bugs.freedesktop.org/show_bug.cgi?id=57601 614 615 * Disable shadow tracking upon server regeneration, and so fix a crash 616 if you restart the server whilst a RandR transform (e.g. rotation) is 617 in effect. 618 https://bugs.freedesktop.org/show_bug.cgi?id=52255 619 https://bugs.freedesktop.org/show_bug.cgi?id=56608 620 621 622 Release 2.20.14 (2012-11-26) 623 ============================ 624 The highlight of this release is gen4, from 965g to gm45. Quite an old 625 bug surfaced in the shader assembly, sparking a chance to review a few 626 design choices within that backend and experiment on fresh ways to 627 workaround the remaining issues. 628 629 * Avoid using inplace XOR'ed uploads for very large buffers 630 https://bugs.freedesktop.org/show_bug.cgi?id=57031 631 632 * Fix the gen4/5 opacity shader 633 https://bugs.freedesktop.org/show_bug.cgi?id=57054 634 635 * Queue a pending vblank request after flip completion 636 https://bugs.freedesktop.org/show_bug.cgi?id=56423 637 638 * Avoid migrating an uninitialised pixmap for use as a render source 639 https://bugs.freedesktop.org/show_bug.cgi?id=47597 640 641 * Improve handing of texture fallbacks for 830/845. 642 https://bugs.freedesktop.org/show_bug.cgi?id=57392 643 644 645 Release 2.20.13 (2012-11-11) 646 ============================ 647 Nothing but bug fixes. Many thanks to everyone who took the time to 648 report their issues, and for their help in improving the driver. 649 650 * Sanity check the platform probe points to our expected i915 device 651 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1069031 652 653 * Prevent 16-bit overflow for computing the sample area to upload of 654 sources for render operations 655 https://bugs.freedesktop.org/show_bug.cgi?id=56324 656 657 * Clamp the drawable box for migration to prevent 16-bit overflow 658 https://bugs.freedesktop.org/show_bug.cgi?id=56591 659 660 * Disable RandR hotplug events if Xinerama is enabled and thereby prevent 661 a crash upon hotplug 662 https://bugs.freedesktop.org/show_bug.cgi?id=55260 663 664 * Call ValidatePicture before attempting to flatten the alphamaps 665 https://bugs.freedesktop.org/show_bug.cgi?id=56367 666 667 * Clip the trapezoid correctly if it ends on the boundary pixel 668 https://bugs.freedesktop.org/show_bug.cgi?id=56395 669 670 * Make sure the pipeline choice is propagated to the scanline wait 671 across a batch flush 672 https://bugs.freedesktop.org/show_bug.cgi?id=47597 673 674 * Set the valid drawable box when choosing placement of BLT composite ops 675 https://bugs.freedesktop.org/show_bug.cgi?id=47597 676 677 * Prevent use-after-free when promoting a partial-GPU bo to a full-GPU bo 678 https://bugs.freedesktop.org/show_bug.cgi?id=56591 679 680 * gen4 opacity spans require the per-rectangle workaround 681 https://bugs.freedesktop.org/show_bug.cgi?id=55500 682 683 * Prevent use of invalid damage pointers when redirecting rendering 684 https://bugs.freedesktop.org/show_bug.cgi?id=56785 685 686 687 Release 2.20.12 (2012-10-20) 688 ============================ 689 More bug reports, more bug fixes! Perhaps the headline feature is 690 that with a secure batches, coming to a 3.8 kernel near you, we may 691 finally have the ability to perform updates to the scanout synchronized 692 to the refresh rate on later SandyBridge and IvyBridge chipsets. It comes 693 at quite a power cost as we need to keep the GPU out of its power saving 694 modes, but it should allow legacy vsync to function at last. But this 695 should allow us to address a longstanding issue with tearing on 696 SandyBridge+. 697 698 * Fix component-alpha rendering on IvyBridge, for example subpixel 699 antialiased glyphs. 700 https://bugs.freedesktop.org/show_bug.cgi?id=56037 701 702 * Flush before some "pipelined" state changes on gen4. The evidence is 703 that the same flushes as required on gen5+ are also required for gen4. 704 https://bugs.freedesktop.org/show_bug.cgi?id=55627 705 706 * Prevent a potential crash when forcing a stall on a busy CPU bo 707 https://bugs.freedesktop.org/show_bug.cgi?id=56180 708 709 [Release 2.20.11 contained a typo causing UXA to fail immediately.] 710 711 Release 2.20.10 (2012-10-14) 712 ============================ 713 The last couple of weeks have been fairly retrospective, a dive into 714 prehistory tidying up the earlier generations which lay languishing as 715 the core progressed and lead to a number of annoying core bugs being 716 fixed. 717 718 * Release DRM master earlier during shutdown so switching between 719 multiple X servers works automatically. 720 https://bugs.freedesktop.org/show_bug.cgi?id=55446 721 722 * Suppress error propagation from DRI2GetMSC and behave as if the pipe 723 was simply off to avoid unexpected errors in the clients 724 https://bugs.freedesktop.org/show_bug.cgi?id=55395 725 726 * A few fixes to i8xx batch emission, ensuring that the GPU is always 727 in a valid state. 728 https://bugs.freedesktop.org/show_bug.cgi?id=55455 729 730 * Prevent a use-after-free during UXA shutdown due to inspecting 731 the glamor flags after the glamor interface had been freed. 732 733 * Prevent a crash combining TearFree and rotations. 734 https://bugs.freedesktop.org/show_bug.cgi?id=55527 735 736 * Correct a missing damage upload along PutImage after using the CPU bo 737 as a source for the GPU. 738 https://bugs.freedesktop.org/show_bug.cgi?id=55508 739 740 * Fix compilation for older glibc without O_CLOEXEC 741 https://bugs.freedesktop.org/show_bug.cgi?id=55577 742 743 * Fix out-of-tree builds failing to recompile the gen4 assemblies 744 https://bugs.freedesktop.org/show_bug.cgi?id=55645 745 746 * Fix non-standard build host configuration handling for intel-gen4asm 747 https://bugs.freedesktop.org/show_bug.cgi?id=55646 748 749 * Fix a potential batch buffer overflow when replacing the last BLT fill 750 operation with a copy 751 https://bugs.freedesktop.org/show_bug.cgi?id=55700 752 753 * Flush the render pipeline more frequently on Ironlake as not all 754 pipelined state changes are. 755 https://bugs.freedesktop.org/show_bug.cgi?id=51422 756 757 * Detect when we need to read the destination for the background raster 758 op during fallbacks. 759 https://bugs.freedesktop.org/show_bug.cgi?id=55810 760 761 * Avoid a potential deference of an invalid CPU mmap after doing an 762 inplace tiled upload. 763 https://bugs.freedesktop.org/show_bug.cgi?id=55812 764 765 * Prevent sign extension when packing the upload data for CopyPlane 766 https://bugs.freedesktop.org/show_bug.cgi?id=55823 767 768 * Fix some render corruption with a UDL slave output and pageflipping 769 770 771 Release 2.20.9 (2012-09-29) 772 =========================== 773 And so it came to pass that a critical bug was uncovered in UXA. The 774 kernel does not like to pageflip when the pipe is off, yet due to the 775 delayed nature of a pageflip and the relaxed checking performed by UXA, 776 we could request a pageflip after turning off the display (DPMS). The 777 kernel rejected that pageflip and the error handling path failed to 778 restore sanity, and when the screen came back it was stuck on the image 779 seen before it went to sleep. (Note that there are also some related 780 kernel bugs, but this update should prevent the most conspicious of the 781 freezes.) Many thanks to Timo Aaltonen for his efforts in tracking down 782 the issue. 783 784 In other news: 785 786 * Prepare for xorg-1.14, the api is being tweaked again. 787 788 * Handle early FreeScreen in UXA. 789 https://bugs.freedesktop.org/show_bug.cgi?id=55346 790 791 * Reenable XvMC support 792 793 * Do not replace the GPU bo when uploading into the shadow/CPU copy 794 https://bugs.freedesktop.org/show_bug.cgi?id=54978 795 796 * Fix use of an uninitialised GC when drawing glyphs to a depth=1 pixmap 797 798 799 Release 2.20.8 (2012-09-16) 800 =========================== 801 Another new small feature, another new release. And a few more bugs 802 fixed as well! But what is this new feature, do I hear you ask? Why, it 803 is nothing less than enabling the ValleyView SDV! The lucky person to 804 have their hands on one will now be able to enjoy X in full TechniColor. 805 806 For the rest of us, a few more bugs were fixed with interesting 807 combinations of software and rendering patterns. 808 809 * Add an extra layer of defence against trying to use a non-GEM device 810 with UXA. This should already be taken care of with the new probe, 811 but the extra sanity check already existed in the code but was doing 812 nothing. 813 https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/962892 814 815 * Fix computation of valid CRTCs bitmask for ZaphodHead 816 Some systems can only handle certain outputs on certain pipes 817 (Screens), and this information was not being propagated through to X 818 and randr correctly, breaking valid configurations and not detecting 819 invalid configurations correctly. 820 821 * Disable global glyph caching with ZaphodHeads. 822 The glyph privates need to be Screen private, but at the moment are 823 global leading to conflicts and invalid rendering with multiple heads. 824 https://bugs.freedesktop.org/show_bug.cgi?id=54707 825 826 * Prevent direct read back of unmappable buffers 827 https://bugs.freedesktop.org/show_bug.cgi?id=54808 828 829 * Tile large uploads whilst replacing the alpha channel 830 https://bugs.freedesktop.org/show_bug.cgi?id=54808 831 832 * Correct the source offset when converting a RENDER composite 833 operation into a BLT composite operation. 834 https://bugs.freedesktop.org/show_bug.cgi?id=54868 835 836 * Correct a minor typo in flattening alphamaps which caused the 837 replacement pixmap to often end up with a height of zero. 838 https://bugs.gentoo.org/show_bug.cgi?id=434860 839 840 * Don't discard the CPU damage if only part of is being replaced. 841 This is most evident when combining software renders like Opera with 842 accelerated rendering. 843 https://bugs.freedesktop.org/show_bug.cgi?id=54937 844 845 Release 2.20.7 (2012-09-08) 846 =========================== 847 Continuing the flurry of releases, this week saw the release of 848 xorg-1.13 bringing with it the first steps towards hotpluggable gpu 849 support and the ability to offload DRI rendering onto other GPUs. In 850 light of that advance, this release includes the support code by Dave 851 Airlie to integrate PRIME into xf86-video-intel and make those new 852 features available. 853 854 Aside from landing PRIME, a few other bugs were fixed since 2.20.6: 855 856 * Fix framebuffer leak on server regeneration 857 858 * Fix texture cache flushing on IvyBridge and Kwin with plastique 859 https://bugs.freedesktop.org/show_bug.cgi?id=54488 860 861 * Redirect large solid fills on SandyBridge+. By large I mean greater 862 than 8192 or 16384 pixels on SandyBridge and IvyBridge respectively. 863 https://bugs.freedesktop.org/show_bug.cgi?id=54134 864 865 * Fix up backlight option handling in the manpage and uxa. 866 https://bugs.freedesktop.org/show_bug.cgi?id=54397 867 868 * Unbreak ZaphodHeads. 869 https://bugs.freedesktop.org/show_bug.cgi?id=52438 870 871 Release 2.20.6 (2012-09-02) 872 =========================== 873 A serious bug that caused a crash on SandyBridge and IvyBridge when 874 mixing CPU and GPU operations on the same buffer, and an annoyance from 875 bad scheduling of windowed swapbuffer updates causing low framerates and 876 jitter. Plus the usual smattering of assertion fixes and a long standing 877 issue with incoherent page access to a streaming buffer. 878 879 * Low frame rates in Blobby Valley when "fullscreen" 880 https://bugs.freedesktop.org/show_bug.cgi?id=54274 881 882 * Incoherent concurrent access with the CPU and GPU 883 https://bugs.freedesktop.org/show_bug.cgi?id=51422 884 https://bugs.freedesktop.org/show_bug.cgi?id=52299 885 886 * Add Option "Backlight" to override automatic selection of the 887 backlight interface. 888 889 * Avoid overwriting the composite operation info when testing if we 890 can transfer the operation to the BLT. 891 892 Release 2.20.5 (2012-08-26) 893 =========================== 894 Another silly bug found, another small bugfix release. The goal was for 895 the driver to bind to all Intel devices supported by the kernel. 896 Unfortunately we were too successful and started claiming Pouslbo, 897 Medfield and Cedarview devices which are still encumbered by propietary 898 IP and not supported by this driver. 899 900 Bugs fixed since 2.20.4: 901 902 * Only bind to Intel devices using the i915 kernel module 903 904 * Regression in the bitmap-to-region code, e.g. icewm window buttons 905 https://bugs.freedesktop.org/show_bug.cgi?id=53699 906 907 Release 2.20.4 (2012-08-18) 908 =========================== 909 Continuing the small bugfix releases, the only real feature is initial 910 enabling for Haswell for the purpose of rendering verification and 911 validation - by no means is it complete! 912 913 Bugs fixed since 2.20.3: 914 915 * Some potential errors along failure paths found by a static analyser 916 with the help of Zdenek Kablac. 917 918 * Eliminate zero-sized rectangles from PolyFillRectangles as the code 919 assumes that they did not exist and so caused corruption. 920 921 * Remove the UXA warning for failing to tile the front buffer if it is 922 disallowed by hardware, and so expected. 923 924 * Fix the validation of the XV pipe parameter. 925 926 * Fix 8x8 tiled pattern fills 927 https://bugs.freedesktop.org/show_bug.cgi?id=53353 928 929 * Fix compile failure when using --with-builderstring 930 931 * Restore w/a flush for gen4 fill/copy/video, fortunately rare 932 operations as at least for fill/copy we prefer to use the BLT. 933 https://bugs.freedesktop.org/show_bug.cgi?id=53119 934 935 * Restore preferred use of the RENDER ring for SNB+ DRI copies. 936 937 Release 2.20.3 (2012-08-04) 938 =========================== 939 Just a minor bugfix for gen4 chipsets (965gm, gm45 and friends) that 940 crept into 2.20.2. As an added bonus, the pessimistic workaround for a 941 GPU hang on gen4 has been relaxed and the shaders have been overhauled 942 which should pave the way to eliminating the last of the uncommon CPU 943 operations, along with immediately realising a small perforamnce 944 improvement. 945 946 Bugs fixed since 2.20.2: 947 948 * Update DPMS bookkeeping after modeset 949 https://bugs.freedesktop.org/show_bug.cgi?id=52142 950 951 * Avoid overlapping gpu/cpu damage after ignoring cpu damage in the 952 consideration of placement for the operation. 953 954 * Enable acceleration by default on 830gm/845g. The GMCH on this pair 955 of chipsets is notoriously incoherent, so the GPU is almost certainly 956 going to hang at some point, though unlikely to hang the system and 957 should automatically disable acceleration (and thence behave 958 identically as if the acceleration was disabled from the start). 959 Option "NoAccel" can be used to disable all 2D acceleration and 960 Option "DRI" can be used to disable all 3D acceleration. 961 https://bugs.freedesktop.org/show_bug.cgi?id=52624 962 963 * Fix vertex bookkeeping for gen4 that was causing corruption in the 964 command stream. 965 966 Release 2.20.2 (2012-07-27) 967 =========================== 968 For the last 9 months, since 2.16.901, we have been shipping a driver that 969 does not work on IvyBridge GT1 systems (HD2500 graphics); we were telling 970 the GPU to use an invalid number of threads for the pixel shader and this 971 in turned caused the GPU to hang. 972 973 Also fixed since the last release just a few days ago: 974 975 * Support for the gmux backlight controller on Apple laptops 976 https://bugs.freedesktop.org/show_bug.cgi?id=52423 977 978 * Fix X -configure not to list this driver as matching any Intel device, 979 just the VGA class devices will do! 980 981 * A crash in SNA when repeatedly switching xrandr rotations 982 983 * Corruption in SNA observed in kwin on IvyBridge 984 https://bugs.freedesktop.org/show_bug.cgi?id=52473 985 986 Release 2.20.1 (2012-07-22) 987 =========================== 988 A week in, grab the brown paper bags, for it is time to reveal a couple 989 of critical bugs that spoilt the 2.20.0 release. 990 991 Firstly we have the restoration of DRI for i810. I am sure that the 992 solitary user will be overjoyed in a couple of years when a new xserver 993 is forced upon him. That enjoyment will be short-lived when as no actual 994 acceleration remains, not even shadow, for the chipset. 995 996 Perhaps a little more wildly felt, I hope!, will be that the SNA 997 fallbacks were broken on 64-bit machines if they required clipping. One 998 little misplaced cast of a pointer, and the screen is filled with 999 corruption. 1000 1001 Among the other tweaks this week: 1002 1003 * A bug affecting gen4 handling of trapezoids was fixed, and CPU 1004 overhead reduced. 1005 https://bugs.freedesktop.org/show_bug.cgi?id=52158 1006 1007 * A fix for a bug causing corruption of a DRI2 unredirected client 1008 window that was resized whilst under a compositor. 1009 1010 * Support for snoopable buffers on non-LLC architectures, coming to 1011 a future kernel. The aim to accelerate transfers between the CPU 1012 and the GPU, in particular to dramatically improve readback 1013 performance, and to further minimise clflushes. 1014 1015 * Improvement to the composite performance on GT2 SandyBridge and 1016 IvyBridge devices, in particular the render copy is significantly 1017 improved. 1018 1019 * Improved handling for when acceleration is disabled, including 1020 permitting DRI2 to remain supported even if the X server believes 1021 the GPU wedged. 1022 1023 * Shadow support was dropped from UXA as it was neither complete nor 1024 correct, use SNA instead. 1025 1026 Release 2.20.0 (2012-07-15) 1027 =========================== 1028 First the big news, a new acceleration method that aims to be faster and 1029 consume far less CPU than UXA is now available for selection at runtime. 1030 This snazzy new architecture can be selected through use of 1031 Option "AccelMethod" "sna" 1032 in your xorg.conf. Whilst it has been under development for some time, it 1033 has not yet had the same degree of widespread testing of UXA, so tread 1034 lightly. Try it and if you spot anything that can be improved, please do 1035 report a bug. 1036 1037 Otherwise we have the usual smattering of bug fixes for UXA: 1038 1039 * Use a white source whilst adding glyphs to the glyph mask 1040 (This fixes blank glyphs if using a font that mixes ARGB and A glyphs.) 1041 1042 * Avoid fallbacks for glyph-to-dst in e.g. gnome-terminal 1043 https://bugs.freedesktop.org/show_bug.cgi?id=50508 1044 1045 * Force unused outputs off when VT switching 1046 https://bugs.freedesktop.org/show_bug.cgi?id=50772 1047 1048 * Copy the fbcon across to the Screen pixmap at startup. 1049 (This patch has been kicking around in the distributions for years.) 1050 1051 * Many missed malloc failures checks and forgotten frees found by a static 1052 analyzer. Thanks Zdenek Kabelac! 1053 1054 * Leak of the back buffer when terminating an application after pageflipping 1055 https://bugs.freedesktop.org/show_bug.cgi?id=50670 1056 1057 * Double check that the pipe is on before emitting a WAIT_ON_EVENT. 1058 In conjunction with an uptodate kernel, this should eliminate any 1059 hangs when changing resolutions or adding/removing displays. 1060 https://bugs.freedesktop.org/show_bug.cgi?id=50668 1061 1062 * Update to new Xorg APIs. Future proofing for the next generation of 1063 hotplug Xorg display servers. 1064 1065 Many thanks to everyone who has reported a bug and otherwise helped to 1066 improve the driver. 1067 1068 Release 2.19.0 (2012-04-29) 1069 =========================== 1070 More stability fixes for UXA and support for another variant of IvyBridge. 1071 Given the severity of the stability fixes, I strongly recommend everybody 1072 to upgrade to 2.19.0. 1073 1074 * Prevent waiting on scanlines whilst not in control of the VT and therefore 1075 whilst referencing foreign CRTC configurations. 1076 1077 * Pixmap (and bo leak) during fallback glyph composition 1078 1079 * Remove broken acceleration for rendering glyphs directly upon the 1080 destination pixmap, exposed by cairo-1.12.0 (and coincidentally fix 1081 another Pixmap leak upon fallback handling). 1082 1083 * Add support for Ivy Bridge GT2 Server chipset [PCI id 0x016a] 1084 1085 * Remove broken damage flushing with CompositeRectangles 1086 https://bugs.freedesktop.org/show_bug.cgi?id=32547 1087 1088 * Fix crash upon server start with multiple monitors 1089 https://bugs.freedesktop.org/show_bug.cgi?id=47395 1090 1091 * Fix composition issues resulting from overly aggressive Pixmap reuse 1092 https://bugs.freedesktop.org/show_bug.cgi?id=47345 1093 1094 Release 2.18.0 (2012-02-24) 1095 =========================== 1096 Time passes, a few more bugs have crept out of the woodwork that are a 1097 compelling reason to update. 1098 1099 Bugs fixed in this release (compared to 2.17.0) 1100 ----------------------------------------------- 1101 1102 * Limit maximum object size so that all of the source, mask and 1103 destination can be mapped into the aperture simultaneously by basing the 1104 limit on the mappable aperture size rather than the size of the total 1105 GATT. 1106 1107 * Incorrect clipping of polygons 1108 https://bugs.freedesktop.org/show_bug.cgi?id=43649 1109 Regression from 2.15.901 1110 1111 * Limit number of VMA cached to avoid hitting the per-process VMA limit 1112 There still is a residual bug in that we seem to have so many objects 1113 floating around in the first place and that still leads to exhaustion 1114 of system limits. 1115 https://bugs.freedesktop.org/show_bug.cgi?id=43075 1116 https://bugs.freedesktop.org/show_bug.cgi?id=40066 1117 1118 * Latency in processing user-input during continuous rendering 1119 1120 Release 2.17.0 (2011-11-16) 1121 ============================== 1122 A few months have passed, and we have accumulated a surprising number of 1123 bug fixes. Oops! We would strongly encourage everyone to upgrade. 1124 1125 Bugs fixed in this snapshot (compared to 2.16.902) 1126 -------------------------------------------------- 1127 1128 * Video clobbering composite batch state 1129 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=635953 1130 1131 Snapshot 2.16.902 (2011-11-13) 1132 ============================== 1133 This is the second release candidate in preparation for the upcoming 1134 2.17.0 release. We will appreciate any feedback we can get from 1135 testing of this snapshot, and thanks to everyone who tested and reported 1136 upon issues in the last snapshot. 1137 1138 A very old bug demonstrating that nobody has ever used alpha maps, and a 1139 couple of more recent mistakes were found. 1140 1141 Bugs fixed in this snapshot (compared to 2.16.901) 1142 -------------------------------------------------- 1143 1144 * Incorrect reuse of surface bindings within a batch for multiple formats 1145 https://bugs.freedesktop.org/show_bug.cgi?id=40926 1146 1147 * Nothing was rendered for text with procedural sources 1148 https://bugs.freedesktop.org/show_bug.cgi?id=31819 1149 1150 * Handle fallbacks involving alpha maps 1151 1152 Snapshot 2.16.901 (2011-10-30) 1153 ============================== 1154 This is the first release candidate in preparation for the upcoming 1155 2.17.0 release. We will appreciate any feedback we can get from 1156 testing of this snapshot. 1157 1158 The basis of this release are to push out a couple of critical stability 1159 fixes for SandyBridge and IvyBridge. There is very little else to see 1160 here. Those 200+ other commits do not exist... 1161 1162 Bugs fixed in this snapshot (compared to 2.16.0) 1163 -------------------------------------------------- 1164 1165 * Workaround blitter hang on SandyBridge and IvyBridge 1166 https://bugzilla.kernel.org/show_bug.cgi?id=27892 1167 https://bugs.freedesktop.org/show_bug.cgi 1168 1169 * Workaround pipe control issues on SandyBridge 1170 1171 * Use correct maximum PS thread count on IvyBridge 1172 1173 * Protect against failed pixmap allocation for XV 1174 https://bugs.freedesktop.org/show_bug.cgi?id=40439 1175 1176 Release 2.16.0 (2011-08-09) 1177 ============================== 1178 A new quarter, a new release! The key feature of this release, looking past 1179 the bug fixes, is the enabling of IvyBridge acceleration. We have also fixed 1180 many bugs and graphical glitches and would encourage everyone to upgrade. 1181 1182 Bugs fixed in this snapshot (compared to 2.15.901) 1183 -------------------------------------------------- 1184 1185 * Build fix for xserver-1.7.7 1186 1187 Snapshot 2.15.901 (2011-07-30) 1188 ============================== 1189 This is the first release candidate in preparation for the upcoming 1190 2.16.0 release. We will appreciate any feedback we can get from 1191 testing of this snapshot. 1192 1193 The highlight of this snapshot is the full enabling of IvyBridge with 1194 acceleration for Render and Xv, along with handling of the shared render 1195 buffer allocations required for Mesa. Also of note is that deep-color 1196 support is enabled (for all chipsets), which allows you to drive your 1197 30-bit monitor at its native colour depth. 1198 1199 Bugs fixed in this snapshot (compared to 2.15.0) 1200 -------------------------------------------------- 1201 1202 * Misuse of the Resource database causing crashes after DRI clients close 1203 https://bugs.freedesktop.org/show_bug.cgi?id=37700 1204 1205 * Crash on large strings 1206 https://bugs.freedesktop.org/show_bug.cgi?id=36860 1207 1208 * Incorrect rendering for some core drawing operations 1209 http://bugs.freedesktop.org/show_bug.cgi?id=28768 1210 http://bugs.freedesktop.org/show_bug.cgi?id=28798 1211 http://bugs.freedesktop.org/show_bug.cgi?id=28908 1212 http://bugs.freedesktop.org/show_bug.cgi?id=29401 1213 1214 * Crash in Xv due to insufficient checks on batch space 1215 https://bugs.freedesktop.org/show_bug.cgi?id=36319 1216 1217 Release 2.15.0 (2011-04-14) 1218 ============================== 1219 We are pleased to announce this major release of the xf86-video-intel 1220 driver, roughly on schedule at 3 months since 2.14.0. With the many bug 1221 fixes in this release, we encourage everyone to upgrade to 2.15. 1222 1223 The priority for this quarter has been simply to be unexciting and stabilise 1224 the driver further, seeking to capitalise upon the improvements elsewhere 1225 in the stack. 1226 1227 Bugs fixed in this snapshot (compared to 2.14.903) 1228 -------------------------------------------------- 1229 1230 * Turn off relaxed fencing by default for older chipsets 1231 This was continuing to destabilize those system, so for the release 1232 we disabled the feature. If you wish to help us debug this, you can 1233 re-enable the optimisation with Option "RelaxedFencing" "True". 1234 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=36147 1235 1236 * Build fix for xserver-1.7.7 1237 1238 * KDE glitches on SNB 1239 [Technically fixed in the previous snapshot, but I'm really pleased 1240 that this got fixed in time for the release!] 1241 https://bugs.freedesktop.org/show_bug.cgi?id=35808 1242 1243 1244 Snapshot 2.14.903 (2011-04-11) 1245 ============================== 1246 This is the third release candidate in preparation for the upcoming 1247 2.15.0 release. We will appreciate any feedback we can get from 1248 testing of this snapshot. 1249 1250 There was a bit of churn since 2.14.902 as a potential fix for a 1251 performance regression was tried but had to reverted when it was found to 1252 cause glitches running Compiz on SandyBridge. Otherwise, there were just a 1253 couple of fixes for building against old xservers and running on an 1254 obscure chipset. 1255 1256 Bugs fixed in this snapshot (compared to 2.14.902) 1257 -------------------------------------------------- 1258 1259 * Prevent issuing an invalid scanline wait command 1260 https://bugs.freedesktop.org/show_bug.cgi?id=35576 1261 1262 * The 946GZ in not a 945, but a 965. 1263 https://bugs.freedesktop.org/show_bug.cgi?id=35854 1264 1265 * Fix tile sizes for gen2 (finally). 1266 1267 * Allow building of recent dri2 changes against old xservers. 1268 1269 1270 Snapshot 2.14.902 (2011-03-29) 1271 ============================== 1272 This is the second release candidate in preparation for the upcoming 1273 2.15.0 release. We will appreciate any feedback we can get from 1274 testing of this snapshot. 1275 1276 As befits testing of release candidates, no major regression was found and 1277 a couple more bugs have been fixed. 1278 1279 Bugs fixed in this snapshot (compared to 2.14.901) 1280 -------------------------------------------------- 1281 1282 * Clients disappearing with pending swaps 1283 1284 * Incorrect clipping of Xv output on i915 across extended desktops 1285 https://bugs.freedesktop.org/show_bug.cgi?id=35346 1286 1287 * Introduction of a LinearFramebuffer option. (Defaults to tiled for 1288 performance and power saving.) 1289 1290 1291 Snapshot 2.14.901 (2011-03-02) 1292 ============================== 1293 This is the first release candidate in preparation for the upcoming 1294 2.15.0 release. We will appreciate any feedback we can get from 1295 testing of this snapshot. 1296 1297 Still no further along my grandiose plans to improve Render performance, 1298 aside from the performance tuning lower in the stack, instead we have had 1299 a steady stream of bug fixes. 1300 1301 Bugs fixed in this snapshot (compared to 2.14.0) 1302 ------------------------------------------------ 1303 1304 * Green pixels within partially off-screen video playback 1305 https://bugs.freedesktop.org/show_bug.cgi?id=24767 1306 1307 * Defer creation of the glyph cache to generation startup 1308 https://bugs.freedesktop.org/show_bug.cgi?id=33412 1309 1310 * Incorrect maximum addresses for video decoder state 1311 https://bugs.freedesktop.org/show_bug.cgi?id=34017 1312 1313 * Failure to handle oversized temporary surfaces 1314 https://bugs.freedesktop.org/show_bug.cgi?id=34399 1315 1316 * Relaxed tiling corruption on gen2 1317 1318 * Crash when destroying a foreign DRI drawable 1319 https://bugs.freedesktop.org/show_bug.cgi?id=34787 1320 1321 1322 Release 2.14.0 (2011-01-07) 1323 =========================== 1324 We are pleased to announce this major release of the xf86-video-intel 1325 driver, on schedule at 3 months since 2.13.0. With the many bug fixes 1326 in this release, we encourage everyone to upgrade to 2.14. 1327 1328 The most notable feature of this release is the inclusion of acceleration 1329 support, both RENDER and XVIDEO, for Sandy Bridge; note that this requires 1330 a 2.6.37 kernel. In improving the acceleration code paths to support Sandy 1331 Bridge, we were also able to improve the performance of the general i965+ 1332 RENDER acceleration. For example on i3, glyph (aa10 and rgb10) performance 1333 is about 3x faster, as is performing small copies between windows, with the 1334 improvement becoming negligible once you hit around 100 pixels square. 1335 1336 1337 Snapshot 2.13.903 (2010-01-04) 1338 ============================== 1339 This is the second release candidate in preparation for the upcoming 1340 2.14.0 release, and if no showstoppers turn up in wider testing will 1341 become the next release. Besides the usual bug fixes, we've included 1342 patches by Mario Kleiner to improve vblank handing which both improve the 1343 timing accuracy and remove a few potential races -- provided you also 1344 have the corresponding fixes in the kernel. 1345 1346 Bug fixes 1347 --------- 1348 1349 * Crash on hot-unpluging with an active fullscreen GL application, e.g. a 1350 compositing WM or video player 1351 https://bugs.freedesktop.org/show_bug.cgi?id=32770 1352 1353 * Freeze upon maximising client-side software renderers, e.g. flash. 1354 https://bugs.freedesktop.org/show_bug.cgi?id=31367 1355 1356 * Fix confusion over G35 generation 1357 https://bugs.freedesktop.org/show_bug.cgi?id=32478 1358 1359 1360 Snapshot 2.13.902 (2010-12-10) 1361 ============================== 1362 This is the first release candidate in preparation for the upcoming 1363 2.14.0 release. Sandybridge support should be now be ready for use, 1364 and we will appreciate any feedback we can get from this snapshot. 1365 Improving the code base for Sandybridge should also have had knock 1366 on effects for earlier chips as well, in particular Ironlake and to 1367 a lesser extent i965. 1368 1369 New requirements compared to 2.13 1370 --------------------------------- 1371 * Librdrm >= 2.4.23 1372 1373 Bug fixes 1374 --------- 1375 1376 * Crash after failing to allocate memory 1377 https://bugs.freedesktop.org/show_bug.cgi?id=31487 1378 1379 * EFAULT during pwrite 1380 https://bugs.freedesktop.org/show_bug.cgi?id=29752 1381 1382 * Mark outputs as on and restore backlight after mode-set 1383 1384 * A hang with i965+ with newer kernels. 1385 1386 1387 Snapshot 2.13.901 (2010-11-05) 1388 ============================== 1389 This is an intermediate snapshot of ongoing driver development. The 1390 primary purpose of this snapshot is to capture some recent 1391 improvements, (particularly in Sandybridge support), for further 1392 testing. 1393 1394 Release 2.13.0 (2010-09-30) 1395 =========================== 1396 We are pleased to announce this major release of the xf86-video-intel 1397 driver, on schedule at 3 months since 2.12.0. With the many bug fixes 1398 in this release, we encourage everyone using 2.12 to upgrade to 2.13. 1399 1400 [This release is functionally identical to the earlier 2.12.902 1401 release candidate.] 1402 1403 New requirements compared to 2.12 1404 --------------------------------- 1405 * Librdrm >= 2.4.22 1406 1407 Bug fixes 1408 --------- 1409 * Attempt to fix infinite MI_WAIT_FOR_EVENT while watching video 1410 https://bugs.freedesktop.org/show_bug.cgi?id=28964 1411 1412 [Various new checks have been added to the video code here, but the 1413 bug fix hasn't yet been verified by the original reporter.] 1414 1415 * Fix buffer-object leak 1416 https://bugs.freedesktop.org/show_bug.cgi?id=26946 1417 1418 * Fix memory leak on server reset 1419 1420 * Fix crash due to unchecked pixmap allocation 1421 https://bugs.freedesktop.org/show_bug.cgi?id=29187 1422 1423 * Fix for video artifacts when using dualscreen 1424 https://bugs.freedesktop.org/show_bug.cgi?id=29213 1425 1426 * Fix for incorrect characters in gnome-terminal when using compiz 1427 https://bugs.freedesktop.org/show_bug.cgi?id=28438 1428 1429 * Fix for hanging, full-screen applications, (flash, compiz, etc.) 1430 https://bugs.freedesktop.org/show_bug.cgi?id=29584 1431 1432 * Fix selection of backlight device on multi-GPU systems 1433 https://bugs.freedesktop.org/show_bug.cgi?id=29273 1434 1435 * Fix to avoid crash with extremely large glyphs 1436 https://bugs.freedesktop.org/show_bug.cgi?id=29430 1437 1438 * Fix for eDP panels incorrectly being given only a single, valid mode 1439 https://bugs.freedesktop.org/show_bug.cgi?id=30069 1440 1441 * Fix GPU hang involving clipped SRC copies 1442 https://bugs.freedesktop.org/show_bug.cgi?id=30120 1443 1444 * Fix to compile for 1.6 series X server. 1445 1446 * Fix to retry framebuffer allocation after an initial failure. 1447 1448 * Fix to disable dri2 after fallbacks are forced on. 1449 1450 Snapshot 2.12.902 (2010-09-28) 1451 ============================== 1452 This is the second release candidate in preparation for the upcoming 1453 2.13.0 release. The comes exactly one week after 2.12.902 and includes 1454 only a handful of changes. 1455 1456 One significant change is that the drive now requires libdrm 2.4.22 1457 (or newer), as several people reported compilation failures of 1458 xf86-video-intel 2.12.901 with libdrm 2.4.21. 1459 1460 Other changes include a fix to compile for the 1.6 series X server, a 1461 fix to retry framebuffer allocation after an initial failure, and a 1462 fix to disable dri2 after fallbacks are forced on. 1463 1464 Snapshot 2.12.901 (2010-09-21) 1465 ============================== 1466 This is the first release candidate in preparation for the upcoming 1467 2.13.0 release. We will appreciate any feedback we can get from 1468 testing of this snapshot. 1469 1470 Bugs fixed in this snapshot (compared to 2.12.0) 1471 ------------------------------------------------ 1472 * Attempt to fix infinite MI_WAIT_FOR_EVENT while watching video 1473 https://bugs.freedesktop.org/show_bug.cgi?id=28964 1474 1475 [Various new checks have been added to the video code here, but the 1476 bug fix hasn't yet been verified by the original reporter.] 1477 1478 * Fix buffer-object leak 1479 https://bugs.freedesktop.org/show_bug.cgi?id=26946 1480 1481 * Fix memory leak on server reset 1482 1483 * Fix crash due to unchecked pixmap allocation 1484 https://bugs.freedesktop.org/show_bug.cgi?id=29187 1485 1486 * Fix for video artifacts when using dualscreen 1487 https://bugs.freedesktop.org/show_bug.cgi?id=29213 1488 1489 * Fix for incorrect characters in gnome-terminal when using compiz 1490 https://bugs.freedesktop.org/show_bug.cgi?id=28438 1491 1492 * Fix for hanging, full-screen applications, (flash, compiz, etc.) 1493 https://bugs.freedesktop.org/show_bug.cgi?id=29584 1494 1495 * Fix selection of backlight device on multi-GPU systems 1496 https://bugs.freedesktop.org/show_bug.cgi?id=29273 1497 1498 * Fix to avoid crash with extremely large glyphs 1499 https://bugs.freedesktop.org/show_bug.cgi?id=29430 1500 1501 * Fix for eDP panels incorrectly being given only a single, valid mode 1502 https://bugs.freedesktop.org/show_bug.cgi?id=30069 1503 1504 * Fix GPU hang involving clipped SRC copies 1505 https://bugs.freedesktop.org/show_bug.cgi?id=30120 1506 1507 Release 2.12.0 (2010-06-24) 1508 =========================== 1509 We are pleased to announce this major release of the xf86-video-intel 1510 2D driver. It contains many correctness and performance improvements 1511 compared to the 2.11 releases. We encourage everyone using 2.11 to 1512 upgrade to 2.12. 1513 1514 [This release contains several bug fixes since the earlier 2.11.901 1515 release candidate---see below for details.] 1516 1517 New requirements compared to 2.11 1518 --------------------------------- 1519 * Libdrm >= 2.4.21 1520 1521 Major performance improvements 1522 ------------------------------ 1523 There have been many performance improvements targeting the 1524 915G/945G/Pineview graphics chipsets (thank to Chris Wilson!). Areas 1525 improved include: 1526 1527 * Major improvements to glyph rendering 1528 1529 * Avoid software fallback when using extended desktops, (for example, 1530 video playback) 1531 1532 * Better performance when using large windows, (for example with 1533 firefox scrolling) 1534 1535 * Avoiding migration ping-pong with gigantic drawing 1536 1537 The following speedups (measured with cairo-perf-trace/cairo-traces) 1538 capture some of the improvements.

We will appreciate any feedback we can get from 1605 testing of this snapshot to improve the 2.12.0 release. 1606 1607 New requirements compared to 2.10 1608 --------------------------------- 1609 * Libdrm >= 2.4.19 1610 1611 Major performance improvements 1612 ------------------------------ 1613 There have been many performance improvements targeting the 1614 915G/945G/Pineview graphics chipsets (thank to Chris Wilson!). Areas 1615 improved include: 1616 1617 * Major improvements to glyph rendering 1618 1619 * Avoid software fallback when using extended desktops, (for example, 1620 video playback) 1621 1622 * Better performance when using large windows, (for example with 1623 firefox scrolling) 1624 1625 * Avoiding migration ping-pong with gigantic drawing 1626 1627 The following speedups (measured with cairo-perf-trace/cairo-traces) 1628 capture some of the improvements. These were measured on a Pineview 1629 system with a very recent X server, (from git just before 1.8.1).

The rendercheck test suite 1654 passes once again and there has been a significant reduction in the 1655 number of errors detected by the cairo test suite (notably center 1656 sampling and EXTEND_NONE behaviors are fixed). 1657 1658 Other notable bug fixes include: 1659 1660 * Fix for bug 28446 Garbled fonts with Mathematica 1661 https://bugs.freedesktop.org/show_bug.cgi?id=28446 1662 1663 * Fixes for page-flipping and other DRI2-handling bugs, (Thanks Jesse 1664 Barnes, and Kristian Hgsberg) 1665 1666 * Avoid corruption when using extended desktops, (for example, video 1667 playback) 1668 1669 Release 2.11.0 (2010-03-29) 1670 =========================== 1671 New in 2.11: DRI2 and page flipping 1672 ----------------------------------- 1673 The most significant new feature of this release is support for new 1674 DRI2 APIs, allowing page flipping to occur for swaps that are 1675 full-screen and not rotated. 1676 1677 Performance improvements in 2.11 compared to 2.10 1678 ------------------------------------------------- 1679 Dramatically improved performance of large pixmaps on 1680 memory-constrained hardware, (such as 945), by using tiling. 1681 Note that this fix is new since the most recent release 1682 candidate for this release (2.10.903). 1683 1684 https://bugs.freedesktop.org/show_bug.cgi?id=25375 1685 1686 Elimination of software fallback with alpha-only pixmap (a fix which 1687 eliminated a full second from the Moblin boot time): 1688 1689 https://bugs.freedesktop.org/show_bug.cgi?id=26189 1690 1691 Notable bug fixes in 2.11 compared to 2.10 1692 ------------------------------------------ 1693 Fix for undesired black borders on some images, (caued several 1694 problems with firefox): 1695 1696 http://bugs.freedesktop.org/show_bug.cgi?id=17933 1697 1698 And other fixes to provide more conformance with existing 1699 software-rendering, (as measures by the cairo test suite), such as the 1700 sampling location for nearest-neighbor sampling. 1701 1702 Other changes 1703 ------------- 1704 Eric Anholt and Daniel Vetter both removed large piles of old and 1705 useless code now that the driver requires kernel modesetting 1706 (KMS). This continues to reduce the mainteance burden of the driver, 1707 making it easier to isolate and fix bugs. 1708 1709 Snapshot 2.10.903 (2010-03-22) 1710 ============================== 1711 Some notable bug fixes 1712 ---------------------- 1713 * Fix unpredictable results in page-flipping code due to access of an 1714 uninitialized variable. 1715 1716 * Two fixes that address a number of long-outstanding failures in the 1717 cairo test suite: 1718 1719 Remove coord-adjust for nearest centre-sampling. 1720 1721 Fill alpha on xrgb images. Closes: 1722 1723 Bug 17933 - x8r8g8b8 doesn't sample alpha=0 outside surface bounds 1724 http://bugs.freedesktop.org/show_bug.cgi?id=17933 1725 1726 * Fix a regression introduced in 2.10.902: 1727 1728 Fatal server error: 1729 i915_emit_composite_setup: ADVANCE_BATCH: 1730 under-used allocation 100/104 1731 1732 Bug 21723 [i915 bisected] rendering makes X crash 1733 http://bugs.freedesktop.org/show_bug.cgi?id=27123 1734 1735 Other minor fixes (avoid trying to print an error message with a freed 1736 string, set a variable to NULL after freeing), and documentation 1737 updates are also included. 1738 1739 Snapshot 2.10.902 (2010-03-15) 1740 ============================== 1741 Some significant bug fixes 1742 -------------------------- 1743 Fix video color problems due to YUV plane ordering issue. This fixed a 1744 regression that showed up recently (only in these release candidates). 1745 1746 Fix recent regression leading to corruption under compiz: 1747 1748 https://bugs.freedesktop.org/show_bug.cgi?id=26814 1749 1750 Further DRI2 improvements/fixes from Mario Kleiner and Jesse Barnes, 1751 (including support for SwapBuffers request with divisor != 0). 1752 1753 Fix build against X server 1.6 branch. 1754 1755 Avoid flooding logs after an error occurs. 1756 1757 And dramatic code cleanups 1758 -------------------------- 1759 Eric Anholt removed several cases of old, useless code, (conditions 1760 that could not occur now that we require KMS, etc.). 1761 1762 Daniel Vetter eliminated piles of code by modernizing the XvMC 1763 memory-management and completely removing the old i830_memory 1764 allocator (i830_allocate_memory, i830_free_memory), etc. 1765 1766 Snapshot 2.10.901 (2010-02-26) 1767 ============================== 1768 The most significant new feature of this release is support for new 1769 DRI2 APIs, allowing page flipping to occur for swaps that are 1770 full-screen and not rotated. 1771 1772 Some significant bug fixes 1773 -------------------------- 1774 * Avoid fallback due to failing to extract pixel value from an 1775 alpha-only solid, (this fix eliminated 1 second from Mobilin boot 1776 time). 1777 1778 https://bugs.freedesktop.org/show_bug.cgi?id=26189 1779 1780 * Handle full-height blits without tearing in CopyRegion 1781 1782 https://bugs.freedesktop.org/show_bug.cgi?id=22475 1783 1784 Several other fixes and cleanups are included as well, (including the 1785 removal of stale utility code that is now maintained in the separate 1786 intel-gpu-tools module). 1787 1788 Release 2.10.0 (2010-01-04) 1789 =========================== 1790 New requirements of 2.10 compared to 2.9 1791 ---------------------------------------- 1792 * Linux kernel with kernel-modesetting (KMS) 1793 1794 All user-modesetting code has now been removed from the driver. 1795 We highly recommend kernel version 2.6.32 or later. 1796 1797 * Libdrm >= 2.4.16 1798 1799 New features in 2.10 compared to 2.9 1800 ------------------------------------ 1801 * New driver debugging options available in xorg.conf 1802 (DebugFlushBatches, DebugFlushCaches, DebugWait). See "man intel" 1803 for more details. 1804 1805 * Video overlay support with KMS. This currently requires Linux 1806 2.6.33, but a backport to 2.6.32 is available here: 1807 1808 http://gitorious.org/daniel-s-linux-stuff/linux-kernel/commits/intel-kms-overlay-for-2.6.32 1809 1810 Notable fixes in 2.10 compared to 2.9 1811 ----------------------------------- 1812 * Fix crash when XRenderComposite is called with a -1 value for 1813 width/height, (crash at login when using compiz). 1814 1815 http://bugs.freedesktop.org/show_bug.cgi?id=24724 1816 1817 * Fix to support larger extended desktops, (such as a 2560x1600 plus a 1818 1920x1200 monitor). 1819 1820 1821 * Fix glyph corruption due to insufficient cache flushing: 1822 1823 https://bugs.freedesktop.org/show_bug.cgi?id=24315 1824 1825 Several other correctness and performance fixes are also included. 1826 1827 Note: The driver code of the 2.10.0 release is identical to that of 1828 the 2.9.99.901 release candidate. The only changes in 2.10.0 compared 1829 to 2.9.99.902 are a minor change to the configure script, and some 1830 small updates to the documentation. 1831 1832 Snapshot 2.9.99.902 (2009-12-10) 1833 ================================ 1834 This is the second release candidate in preparation for the upcoming 1835 2.10.0 release. We will appreciate any feedback we can get from 1836 testing of this snapshot to improve the 2.10.0 release. 1837 1838 Compared to the previous snapshot, this snapshot now correctly 1839 verifies that libdrm 2.4.16 (or newer) is available. The previous 1840 snapshot also required libdrm 2.4.16 for correct functionality, but 1841 neglected to notify the user of this at configure, compile, or install 1842 time and would instead simply fail to run. 1843 1844 Snapshot 2.9.99.901 (2009-11-30) 1845 ================================ 1846 This is the first release candidate in preparation for the upcoming 1847 2.10.0 release. We will appreciate any feedback we can get from 1848 testing of this snapshot to improve the 2.10.0 release. 1849 1850 With this snapshot, the xf86-video-intel driver requires kernel 1851 modesetting (KMS) as all of the user modesetting (UMS) support has 1852 been removed from the driver. 1853 1854 Release 2.9.0 (2009-09-28) 1855 ========================== 1856 We are pleased to announce the 2.9.0 release of the xf86-video-intel 1857 driver. (If you have been following along at home, this release is 1858 identical to the 2.8.99.902 release candidate other than the version 1859 number). 1860 1861 New features in 2.9 compared to 2.8 1862 ----------------------------------- 1863 * Support for the B43 chipset. 1864 1865 Major fixes in 2.9.0 compared to 2.8.0 1866 -------------------------------------- 1867 * Multiple fixes to make the driver stable for 8xx chipsets, (855GM, 1868 865G, etc.). The 2.8 driver series was extremely unstable with many 1869 of these chipsets. 1870 1871 https://bugs.freedesktop.org/show_bug.cgi?id=22904 (and many duplicates) 1872 https://bugs.freedesktop.org/show_bug.cgi?id=22947 1873 1874 * Add support for BACKLIGHT property when using kernel modesetting 1875 (KMS). This allows backlight adjustment with programs such as 1876 "xbacklight -set <percentage>" or "xrandr --set BACKLIGHT <value>". 1877 1878 https://bugs.freedesktop.org/show_bug.cgi?id=20963 1879 1880 * Fix so that "xrandr --scale" works when using KMS. 1881 1882 https://bugs.freedesktop.org/show_bug.cgi?id=22893 1883 1884 * Fix segfaults of X server when logging out. 1885 1886 https://bugs.freedesktop.org/show_bug.cgi?id=20516 1887 1888 * Avoid falling back to software for 1-bit alpha-only masks. 1889 1890 https://bugs.freedesktop.org/show_bug.cgi?id=23184 1891 1892 * Fix pixel sampling position for 8xx chipsets, (fixes some cairo-test 1893 suite failures). 1894 1895 Snapshot 2.8.99.901 (2009-09-09) 1896 ================================ 1897 This is the first release candidate in preparation for the upcoming 1898 2.9.0 release. We will appreciate any feedback we can get from testing 1899 of this snapshot to improve the 2.9.0 release. 1900 1901 See the commit log for changes in this release, and developers, please 1902 provide me summaries for any major features in this release that you 1903 think should appear in NEWS and in the 2.9.0 release notes. 1904 1905 Note: We are still investigating failures with 865G chipsets, (these 1906 failures existed in the 2.8 series as well). We are hoping to fix 1907 these failures before the 2.9.0 release. 1908 1909 Release 2.8.0 (2009-07-20) 1910 ========================== 1911 We are pleased to present this major release of the xf86-video-intel 1912 driver. This release is very similar to the 2.7.99.902 release 1913 candidate but includes a couple of additional bug fixes, (for bugs 1914 #22760 and @22483). 1915 1916 Compared to the 2.7 releases this driver contains several new features 1917 and many bug fixes. The driver now depends on X server 1.6 or later, 1918 and eliminates several obsolete code paths, (XAA and EXA removed in 1919 favor of UXA, DRI1 support eliminated). The driver certainly will work 1920 best with an i915 module from a recent kernel (2.6.31) and with 1921 kernel-modesetting (KMS, specified by loading i915 with the option 1922 "modeset=1"). 1923 1924 New features in 2.8.0 compared to 2.7 1925 ------------------------------------- 1926 * Remove XAA/EXA/DRI1 and NoAccel, and only support UXA/DRI2 now 1927 (requiring xserver 1.6). 1928 1929 * VLD support added into XvMC for Mpeg2, which decreases CPU usage 1930 when playing video. 1931 1932 Major fixes in 2.8.0 compared to 2.7 1933 ------------------------------------ 1934 * Fix broken front-buffer rendering 1935 https://bugs.freedesktop.org/show_bug.cgi?id=19174 1936 1937 * Fix disabling of XvMC disabled 1938 https://bugs.freedesktop.org/show_bug.cgi?id=20790 1939 1940 * Fix broken VT switch on some machines 1941 https://bugs.freedesktop.org/show_bug.cgi?id=19578 1942 1943 * Improve performance of trapezoid rendering for UXA 1944 https://bugs.freedesktop.org/show_bug.cgi?id=21376 1945 1946 * Vblank sync'd GL buffer swap (fixing video tearing under composite) 1947 https://bugs.freedesktop.org/show_bug.cgi?id=20664 1948 1949 * Fix G41 DRM support 1950 https://bugs.freedesktop.org/show_bug.cgi?id=21095 1951 1952 * Fix crash on some 8xx 1953 https://bugs.freedesktop.org/show_bug.cgi?id=18974 1954 1955 Various fixes for GPU hangs, and more... 1956 1957 Snapshot 2.7.99.902 (2009-07-13) 1958 -------------------------------- 1959 This is the first release candidate in preparation for the upcoming 1960 2.8.0 release. Most major and critical bugs should be fixed, but some 1961 minor bugs may still be present. We will appreciate any feedback we 1962 can get from testing of this snapshot to improve the 2.8.0 release. 1963 1964 Snapshot 2.7.99.901 (2009-06-10) 1965 -------------------------------- 1966 This is the first release candidate in preparation for the upcoming 1967 2.8.0 release. Most critical bugs should be fixed, but some major 1968 bugs may still be present. We will appreciate any feedback we can 1969 get from testing of this snapshot to improve the 2.8.0 release. 1970 1971 Some of the major fixes in this snapshot include: 1972 1973 * Several fixes for intermittent GPU hangs/crashes, (some of 1974 which already appeared in the 2.7.1 release) 1975 1976 * Fix to avoid X crash when viewing large images in browser 1977 1978 * Fix X server failure when running old (non-GEM) kernel 1979 1980 * Fixes for SDVO LVDS mode detection 1981 1982 * Fix major performance regression of trapezoid rendering 1983 compared to XAA/EXA 1984 1985 * New support for tear-free video when using KMS 1986 1987 * New support for tear-free DRI2 CopyRegion 1988 1989 Snapshot 2.7.99.1 (2009-04-28) 1990 ------------------------------ 1991 This is a development snapshot very early in the process toward 1992 developing 2.8. There have been some big changes to the code, and 1993 we're anxious to get feedback on these changes as early as possible. 1994 1995 Here is a summary of the biggest changes: 1996 1997 * Driver now depends on X server 1.6 or later 1998 1999 * Eliminate XAA and EXA support (in favor of UXA) 2000 2001 * Eliminate DRI1 support 2002 2003 * Fixes for running without DRI at all 2004 2005 These code removals represent a deletion of a substantial amount of 2006 code, (and hopefully piles of bugs), as well as reduce the maintenance 2007 effort going forward as the number of combinatorial configurations for 2008 the driver are greatly reduced. This means that users are much more 2009 likely to be running code that has actually been tested, and it will 2010 be much easy for developers to replicate bugs that users experience. 2011 2012 One of the things that would be most useful in testing this release is 2013 to revisit any outstanding bugs that you have previously reported. If 2014 the buggy behavior is gone, (or the bug is no longer relevant---such 2015 as a bug that's specific to XAA only), please feel free to indicate so 2016 in bugzilla or even just close the bug. 2017 2018 If you confirm that the bug is still present, please indicate so in 2019 the bug report. (I was going to ask that you select a 1.7.99 version, 2020 but it looks like bugzilla only has versions for products not 2021 compoenents, while we use a "xorg" product and a "driver/intel" 2022 component.) We definitely want to make any such confirmed bugs a 2023 priority, so it would be nice to have a consistent mechanism to search 2024 for these bugs. Suggestions are welcome on the best approach. 2025 2026 Thanks in advance for any testing or feedback on this snapshot. 2027 2028 Release 2.7.0 (2009-04-15) 2029 -------------------------- 2030 Compared to the 2.6 series, 2.7.0 has a large number of bug fixes, but 2031 also a few significant features, such as: 2032 2033 SDVO-TV support, available on ADD2 card (bug#9992) and 2034 D945GCLF2 board (bug#17776). 2035 2036 Basic SDVO-LVDS support 2037 2038 XV video display without tearing 2039 [Though this isn't working for all users yet, see 2040 https://bugs.freedesktop.org/show_bug.cgi?id=21076 ] 2041 2042 Various fixes for UXA, DRI2, and Kernel modesetting. 2043 2044 We encourage users to use kernel modesetting and UXA acceleration with 2045 this release, which should give the best performance and 2046 robustness. When KMS is available, UXA is the default acceleration 2047 used by the driver, (EXA is the default otherwise). 2048 2049 Known issue: 2050 2051 Some Linux kernel versions (such as 2.6.29) are known to have 2052 broken PAT code that causes recent versions of this driver to 2053 fail, (which can manifest as the X server simply not 2054 starting). This can be verified by adding the "nopat" option 2055 to the kernel command-line and seeing the failure go away. We 2056 hope that newer kernels in the 2.6.29.x as well as 2.6.30 and 2057 above will have working PAT code. 2058 2059 Some of the most notable bugs fixed in 2.7.0 include: 2060 2061 [GM45 965GM] bad htotal causes panel startup failure 2062 https://bugs.freedesktop.org/show_bug.cgi?id=17292 2063 2064 [xrandr TV] need TV output property control 2065 https://bugs.freedesktop.org/show_bug.cgi?id=12763 2066 2067 [TV] "xrandr --set TV_FORMAT" gets BadMatch error 2068 https://bugs.freedesktop.org/show_bug.cgi?id=16566 2069 2070 [945 tiling] Low performance due to no A17 workaround 2071 https://bugs.freedesktop.org/show_bug.cgi?id=16835 2072 2073 [TV]Flicker when launching applications in the 2.4-branch 2074 https://bugs.freedesktop.org/show_bug.cgi?id=17405 2075 2076 [945GM FBC] FBC causes underruns & flicker 2077 https://bugs.freedesktop.org/show_bug.cgi?id=18651 2078 2079 [xv] Textured video suffers from tearing 2080 https://bugs.freedesktop.org/show_bug.cgi?id=19635 2081 2082 [G45] Random hangs with UXA 2083 https://bugs.freedesktop.org/show_bug.cgi?id=19734 2084 2085 [945GM] Any 3D app is slow in resolution higher than 800x600 2086 with UXA+DRI2, due to tiling 2087 https://bugs.freedesktop.org/show_bug.cgi?id=19738 2088 2089 [i915 UXA,EXA] rotation messes display with tiling on 2090 https://bugs.freedesktop.org/show_bug.cgi?id=20265 2091 2092 [G45] DRI2/UXA gives solid white instead of transparency 2093 https://bugs.freedesktop.org/show_bug.cgi?id=20321 2094 2095 LVDS output not detected 2096 https://bugs.freedesktop.org/show_bug.cgi?id=20517 2097 2098 xf86-video-intel-2.6.3: Xv crashes X server 2099 https://bugs.freedesktop.org/show_bug.cgi?id=20525 2100 2101 [G965 non-GEM] systray in KDE 4 completely broken 2102 https://bugs.freedesktop.org/show_bug.cgi?id=20527 2103 2104 [SDVO-TV]the desktop is teared in four sections on the screen 2105 https://bugs.freedesktop.org/show_bug.cgi?id=20550 2106 2107 Intel video driver 2.6.3 crashes with XVideo 2108 https://bugs.freedesktop.org/show_bug.cgi?id=20563 2109 2110 [855GM] Xv crash with non-KMS 2111 https://bugs.freedesktop.org/show_bug.cgi?id=20585 2112 2113 2.6.99.902 breaks native 1680x1050 mode on TMDS -- EDID miss 2114 https://bugs.freedesktop.org/show_bug.cgi?id=20594 2115 2116 [945GM TV] 2.6.99.902 sets a too high CONTRAST-value 2117 https://bugs.freedesktop.org/show_bug.cgi?id=20670 2118 2119 [915GM] fail to detect LVDS with new VBT code 2120 https://bugs.freedesktop.org/show_bug.cgi?id=20752 2121 2122 [regression i965]tiled output when start X 2123 https://bugs.freedesktop.org/show_bug.cgi?id=20803 2124 2125 2.6.99.902: LVDS wrongly detected as disconnected 2126 https://bugs.freedesktop.org/show_bug.cgi?id=20826 2127 2128 vt switching fails and crashes X 2129 https://bugs.freedesktop.org/show_bug.cgi?id=20863 2130 2131 [HDMI] The screen will flicker when some application runs on 2132 G45-64 2133 https://bugs.freedesktop.org/show_bug.cgi?id=20875 2134 2135 TexturedVideo is offsetted wrongly on dualhead 2136 https://bugs.freedesktop.org/show_bug.cgi?id=20980 2137 2138 [EXA] xvideo hang X 2139 https://bugs.freedesktop.org/show_bug.cgi?id=21027 2140 2141 [EXA] x11perf performance regression 2142 https://bugs.freedesktop.org/show_bug.cgi?id=21029 2143 2144 And many others... 2145
