How to get OpenCL 1.2 on Ubuntu 16.04 x86_64?

I've found some conflicting information.

 

It seems OpenCL 1.2 is only possible on Ubuntu 14.04 (and you must downgrade the Linux kernel to 3.19):

Recommended Open CL SDK for use with AMDGPU-PRO on Linux?

 

Also, some AMD support folks recommend installing APP SDK 3.0, but other AMD support folks say that this is deprecated / incompatible with the newer amgdpu-pro drivers:

Possible bug in AMD App SDK 3.0 install script?

 

I'm trying various combinations, but I think the motherboard I'm using won't work because it provides an Intel graphics chip (i915) and doesn't provide any way to  disable it - and there seems to be a weird conflict with X11/RX 580/i915. I tried blacklisting the i915, but X11 still seems to find it (via fbdev iirc).

 

So I've ordered a new motherboard and Ryzen CPU. When I get it, should I be able to use OpenCL += 1.2 with Ubuntu 16.04 or should I downgrade to 14.04? (and downgrade the kernel to 3.19?)

 

Thanks!
