Bug detailed description:
----------------------------------------------
GPU hang when running unigine demos (Sanctuary/Tropics) on HSW GT3e.
The problem doesn’t exist on IVB,BYT and HSW-D. Please see xorg.0.log,
dmesg.log and i915_error_state.log.
It’s Mesa regression, but it can’t be fixed by installing Mesa (good commit).
Only in place of i965_dri.so, it can be fixed. So I can’t bisect.
The Mesa good commit is git- 73c78c5, the bad commit is git-7c3138a.
Reproduce steps:
---------------------------------------------
1.xinit&
2.export LD_LIBRARY_PATH=bin/:$LD_LIBRARY_PATH
export force_glsl_extensions_warn=true
3.vblank_mode=0 ./bin/Sanctuary -video_app opengl -data_path ../ -sound_app
null -system_script sanctuary/unigine.cpp -engine_config ../data/unigine.cfg
-video_mode -1 -video_fullscreen 1 -extern_define PHORONIX -video_width 1920
-video_height 1080</pre>
