It has no such issue on Capella, Piketon and Huronriver. I tested with firefox 4.0b12pre. And we need to set MOZ_GLX_IGNORE_BLACKLIST or it can't run. libGL: OpenDriver: trying /opt/X11R7/lib/dri/i915_dri.so i915_program_error: Bad inst->DstReg.Index: 3 firefox-bin: i915_program.c:248: i915_emit_texld: Assertion `dest == ((((((dest)>>29)&0x7))<< 29) | (((((dest)>>24)&0xf)) << 24) | (0 << 20) | (1 << 16) | (2 << 12) | (3 << 8) | (4 << 4) | (5 << 0))' failed. The webpages that will crash the firefox: copy-tex-image-and-sub-image-2d.html, gl-clear.html, gl-teximage.html, read-pixels-test.html, tex-image-and-sub-image-2d-with-array-buffer-view.html, tex-image-and-sub-image-2d-with-image-data.html, tex-image-and-sub-image-2d-with-image.html, tex-image-and-sub-image-2d-with-video.html, tex-image-with-format-and-type.html, texture-active-bind.html, texture-complete.html, texture-formats-test.html, texture-npot.html, texture-transparent-pixels-initialized.html Reproduce steps: ------------------------- 1. download webglc test suite from https://cvs.khronos.org/svn/repos/registry/trunk/public/webgl/sdk/tests/ 2. run those tests with MOZ_GLX_IGNORE_BLACKLIST=1 /GFX/Test/Firefox/firefox/firefox webgl-conformance-tests.html
The problem also exists on Pineview with Firefox(4.0.1). -------------------------- Firefox: Mozilla Firefox 4.0.1 Platform: Pineview Libdrm: (master)2.4.25-1-g61be94018ae9c403517d53f69357719224fa6ff3 Mesa: (master)c5903ed4541ec4f9389e33ba27c9527afa87ec44 Xf86_video_intel:(master)2.15.0-18-g340cfb7f5271fd1df4c8948e5c9336f5b69a6e6c Cairo: (master)e21b373c94b1edb2828d4fee7ff45060fb22dbda Kernel: (drm-intel-next)90711d50d0bc3dde0c2bd214abda8cdaf62f7b2e
commit 556a47a2621073185be83a0a721a8ba93392bedb Author: Eric Anholt <eric@anholt.net> Date: Tue Jul 12 15:31:39 2011 -0700 i915: Add support for gl_FragData[0] for output color. We advertised ARB_draw_buffers, but either fell back to software when using this output, or assertion failed. Fixes glsl-fs-fragdata-1, and failures in some webgl conformance tests.
