CTS version:
git at 67ae88f31295
command:
./glcts --deqp-case=ES31-CTS.shader_bitfield_operation*
Environment:
Mesa built with: --enable-debug
export MESA_GLES_VERSION_OVERRIDE=3.1
export MESA_EXTENSION_OVERRIDE=GL_ARB_compute_shader
------------------
The shader bitfield test of the OpenGL ES 3.1 CTS, run builtin GLSL functions
on various types set up in std430 layout. For example the:
ES31-CTS.shader_bitfield_operation.frexp.vec4_0, the will run frexp(vec4,
vec4), then dispatch compute, mapbufferrange out the result and compare with an
expected result.
Unfortunately there is a big gap between the numbers of passing test for
different HW.I attach a list of failing test for HSW, BDW and SKL.
