Gen8 and later GPUs</link> are supported by the Intel NEO OpenCL
runtime that is provided by the
<package>intel-compute-runtime</package> package. For Gen7 GPUs,
the deprecated Beignet runtime can be used, which is provided
by the <package>beignet</package> package. The proprietary Intel
OpenCL runtime, in the <package>intel-ocl</package> package, is
an alternative for Gen7 GPUs.

The <package>intel-compute-runtime</package>, <package>beignet</package>,
or <package>intel-ocl</package> package can be added to
<xref linkend="opt-hardware.opengl.extraPackages"/> to enable OpenCL
support. For example, for Gen8 and later GPUs, the following
configuration can be used:
<programlisting><xref linkend="opt-hardware.opengl.extraPackages"/> = [
intel-compute-runtime
