Introduction

If you have ever heard of OpenCL, then you might wondering how to install it. Luckily Debian provides all you need in their repositories.

What you need

I did my experiments with a Dell notebook with Debian Buster on it. The notebook has an Intel graphic chip. This makes it quite simple, because the kernel module 'i915' is already provided in the kernel. I have a Broadwell chip which works without firmware. Newer chips need firmware. The 'firmware-misc-nonfree' package provides the firmware for newer Intel graphic cards. Please read the package description for more details.

Package installation

You need two package. So let's install them. The first one is the generic OpenCL ICD loader. The second one is OpenCL library for Intel GPUs.

apt-get install ocl-icd-libopencl1 beignet-opencl-icd

That was quite boring. Let's go to the next step.
