OpenCL on etnaviv?

On the etnaviv side OpenCL is possible but nothing has done in that
direction and
needs work to get it up and running. Hardware wise it should work on GPUs with
SSBOs and Images support. Intuitively it should work on most Vivante GPUs. Also
you might have a look https://en.wikipedia.org/wiki/Vivante_Corporation

I am a big vulkan newbie but I think the baseline for vulkan is ES 3.1. So any
GPU where we can support ES 3.1 could also be driven by the Vulkan API.

But the Vulkan road for etnaviv is even longer one. I think gles 3.0 is more
important at the moment. So do not expect anything in that area in the near and
far future.
