ad897fff7730298c21289768d9b1b55f3d166ac5 is the first bad commit commit ad897fff7730298c21289768d9b1b55f3d166ac5 Author: Brian Paul <brianp@vmware.com> Date: Wed Feb 29 20:55:50 2012 -0700 mesa: use _mesa_rebase_rgba_float/uint() in glReadPixels code See the comments for _mesa_rebase_rgba_float() for details. Fixes https://bugs.freedesktop.org/show_bug.cgi?id=46679 NOTE: This is a candidate for the 8.0 branch. Reviewed-by: José Fonseca <jfonseca@vmware.com> Actually, I think mesa is right and the test is wrong. The NVIDIA driver fails the same tests as Mesa. It looks like the test is doing the wrong thing when computing the expected result colors when the texture is luminance, L/A or intensity. I'll try to fix that. Fixed with commit 731669c0667325f311fcbcd0f1be63801faaec82 to piglit. |
