[Buildroot] [PATCH 0/6] OpenCL support

[Thomas Petazzoni <thomas.petazzoni@bootlin.com>]

Hello,

This series started with the patches from Valentin enabling mesa3d as
an OpenCL provider, and clinfo as a first package using OpenCL.

OpenCL, like OpenGL or EGL, is an API specified by Khronos, so it can
have multiple implementations. Therefore, tying clinfo directly with
mesa3d wasn't the right thing to do.

And indeed, we have at least another package in Buildroot that
provides an OpenCL implementation: nvidia-driver, and clinfo builds
fine against it.

So, this series introduces a virtual-package for OpenCL, and makes
nvidia-driver and mesa3d providers of OpenCL. In order to make
nvidia-driver a provider of OpenCL, we need to teach mesa3d-headers
how to install OpenCL headers, because nvidia-drivers doesn't provide
them (just like it doesn't provide GL, EGL, etc. headers).
