I bisected the original failure between 593484a1c4dd12b5a4f3a7dceae62911a3a07f3e and 10.1 to: commit 2a3d1e2e06ce74801ccbfd349558d44653b9692f Author: Ian Romanick <ian.d.romanick@intel.com> Date: Wed Nov 20 13:48:36 2013 -0800 mesa: Remove support for GL_MESA_texture_array This extension enabled the use of texture array with fixed-function and assembly fragment shaders. No applications are known to use this extension. NOTE: This patch regresses GL_TEXTURE_1D_ARRAY and GL_TEXTURE_2D_ARRAY cases of the copyteximage piglit test. The test is incorrectly using texture arrays with fixed function while only requiring the GL_EXT_texture_array extension. A fix for the test has been posted to the piglit mailing list. http://lists.freedesktop.org/archives/piglit/2013-November/008639.html Signed-off-by: Ian Romanick <ian.d.romanick@intel.com> Reviewed-by: Jordan Justen <jordan.l.justen@intel.com> Reviewed-by: Brian Paul <brianp@vmware.com> I haven't bisected between 10.1 and master to find the fix, though. And I bisected the fix to: commit b2ad3dbfa436ff205bffca5333ec0061208d52ae Author: Ian Romanick <ian.d.romanick@intel.com> Date: Mon Dec 16 15:01:54 2013 -0800 meta: Use GLSL to decompress 2D-array textures Signed-off-by: Ian Romanick <ian.d.romanick@intel.com> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=72582 Reviewed-by: Eric Anholt <eric@anholt.net> I'm not sure this is worth fixing. Backporting the meta changes to 10.1 could be fairly destabilizing. Verified.Fixed. |
