Running ARM Compute Library it seems there is no default display suport on ( x ) wayland.
~/ComputeLibrary/build# LD_LIBRARY_PATH=/home/root/ComputeLibrary/build/ ./tests/arm_compute_benchmark [CORE][09-02-2019 11:23:05][INFO] Can't find valid Mali GPU. Target is set to default. EGL: Warning: No default display support on wayland terminate called after throwing an instance of 'std::runtime_error' what(): in setup_context src/runtime/GLES_COMPUTE/GCScheduler.cpp:88: Failed to get display: 0x3000. Aborted (core dumped)
On imx8 device it looks like iGPU driver doesn't supportEGL_DEFAULT_DISPLAY.
