+          To determine the model of the Intel GPU, run
+          <command>lspci -nn | grep -Ei 'VGA|DISPLAY'</command> first.
+          It will output some information about the GPU.  If the output
+          contains <literal>Meteor Lake</literal>, the GPU model is
+          <literal>MTL</literal>.  Otherwise, follow
+          <ulink url='https://dgpu-docs.intel.com/devices/hardware-table.html'/>
+          to find the entry for your GPU and the model of the GPU should
+          be in the <quote>Architecture</quote> column.  The Xe and XeHPG
+          architectures are covered by the <literal>GEN12</literal> model.
+        </para>
+        <!-- TODO: The info about MTL is my best guess, the referred Intel
+        page does not contain Meteor Lake GPU PCI devicd ID as at Feb 2024.
+        XeHPC is not enabled by default but they are some data center GPUs.
+        Not sure if anyone will run LFS in a data center. -->
