Can you please link to the corresponding OpenCL driver changes? I'm
assuming this relates to the new-driver-to-be-adopted, instead of
Beignet?

How is the story/schedule looking for adopting the new driver to
distros?

Seeing the userspace counterpart and tests will help in assessing the
suggested changes.
