System Environment: -------------------------- Arch i386 Platform G45 945GM Libdrm: (master)73b59c894380995a2889b98e79acadd2da0bb237 Mesa: (master)241c3a1d8001fc5a30e2af4b4636b48e6f99690a Xserver: (server-1.6-branch)3044711412d0a08ba65a491bd2441c0c8980f5e2 Xf86_video_intel: (master)7c48c21b22bf5862c5a35bda1635753cc5a7197c Bug detailed description: ------------------------- This issue happens on both i965 and i915 platforms. The following test cases have been impacted glean/logicOp PASS->FAIL on both G45 and 945GM oglc/depth-tex.c PASS->FAIL on both G45 and 945GM glean/coloredTexPerf2 PASS->NSPT on G45, which is due to exactRGBA failed glean/coloredLitPerf2 PASS->NSPT on G45, which is due to exactRGBA failed oglc/volume-tex.c FAIL->TIMEOUT_with_fail on both G45 and 945GM, may also be related to this. This is caused by following commit: commit 00413d87426f14df47d90ba3c995e1889e9f88ca Author: Eric Anholt <eric@anholt.net> Date: Fri Aug 28 15:01:56 2009 -0700 i965: Use VBOs in the VBO module on 965, now that we have ARB_map_buffer_range. This looks like it's a small win on blender. Reproduce steps: ---------------- 1.xinit& 2. run glean/oglc case
Note that, oglc case depth-tex.c failure is 100% reproducible on one of our G45 with 2G memory, stolen memory 32M, Aperture size 256M, and is 50% reproducible on another G45 with 1G memory, stolen memory 32M, Aperture size 256M.
This issue has gone with: commit cbde2765804a4fc62bcf092230a01376aedbf2cd Author: Eric Anholt <eric@anholt.net> Date: Wed Sep 2 12:17:28 2009 -0700 Revert "i965: Use VBOs in the VBO module on 965, now that we have ARB_map_bu This reverts commit 00413d87426f14df47d90ba3c995e1889e9f88ca. Even with fixes, using ARB_map_buffer_range in the VBO module isn't showing up as a significant win, and some cases apparently regressed. Bug #23624.
