<pre>Hi Clayton,
I doublechecked this test on my Haswell (Intel® HD Graphics 4600) and caught
about 30% of fails.
Here is log output of the fail:
./glcts -n
"KHR-GLES31.core.tessellation_shader.tessellation_control_to_tessellation_evaluation.gl_tessLevel"
Writing test log into TestResults.qpa
dEQP Core git-c48d72686423076b78b205fdb193d142a38f747a (0xc48d7268) starting..
target implementation = 'X11 EGL/GLX'
Test case
'KHR-GLES31.core.tessellation_shader.tessellation_control_to_tessellation_evaluation.gl_tessLevel'..
Fail (Invalid inner/outer tessellation level used in TE stage at
esextcTessellationShaderTCTE.cpp:3671)
DONE!
Test run totals:
Passed: 0/1 (0.0%)
Failed: 1/1 (100.0%)
Not supported: 0/1 (0.0%)
Warnings: 0/1 (0.0%)
It passed 100% (100/100) on the 13.0.6 mesa (I've run it 100 times in a row
having 1 sec of delay) and it got failed ~30% on the 17.0.0 mesa so I've made
bisect and got following result:
e6ae19944d977dc91bc45adff679337182c20683 is the first bad commit
commit e6ae19944d977dc91bc45adff679337182c20683
