Darktable doesn't recognize Intel Graphics 620's OpenCL (beignet) in Fedora 27

I am writing this question since I had no problem in years of using OpenCL with nVidia graphics in fedora and testing Darktable with it. But now in Fedora 27 I am trying to use Darktable with Intel Graphics opencl capability but when I do darktable -d opencl I get this response as it doesn't recognize:

and when I do clifo it winds three devices. I thought it should find only two, my CPU and my GPU. My CPU is Intel Core i7-7500U and that's it.

I have installed these packages: ocl-icd, opencl-filesystem, opencl-utils-devel and beignet. I think these cover all the necessary dependencies.

The question is: Is it possible to use Darktable's opencl capability with this GPU or not? and how can I do it using beignet and Fedora 27?
