About 700 piglit tests regressed on r100. This includes, but is not limited to: All 648 subcases of clipflat fbo-1d fbo-clearmipmap fbo-sys-sub-blit gen-nonzero-unit ... At least fbo-clearmipmap bisected to the following commit. I did this bisect using 'git bisect run' with that one test, and I haven't verified all the others yet. Tested on: 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV200 [Radeon 7500/7500 LE] This commit is in Mesa 11.0. d21320f6258b2e1780a15c1ca718963d8a15ca18 is the first bad commit commit d21320f6258b2e1780a15c1ca718963d8a15ca18 Author: Roland Scheidegger <sroland@vmware.com> Date: Thu Jul 16 03:18:20 2015 +0200 radeon: fix some potential big endian issues The formats chosen (both by texture format choser, fbo storage allocation) are different for big endian not just for rgba8 but also lower bit width formats (why I don't actually know). Even the function to test for renderable formats used different formats, however the actual colorbuffer setup did not. And the blitter did not take that into account neither. Untested (what could possibly go wrong...). Acked-by: Marek Olšák <marek.olsak@amd.com>
