AMDGPU-PRO 18.50 vs. ROCm 2.0 OpenCL Performance

[Etherman]

Had tried but currently was falling back to CPU rendering for some reason, didn't have time to explore to see if it was bug in ROCm or a Blender issue.

There's an env variable for enabling support for unsupported opencl implementations for
Blenders cycles renderer.
Maybe that is needed for rocm.

Happen to have any documentation on that env var?

Probably referring to

CYCLES_OPENCL_SPLIT_KERNEL_TEST=1

This thread describes the reasoning.
