    <note>
      <para>
        The measurements above, and the Contents below, are for a full build.
        Many people will not wish to install drivers they cannot use, so the
        following paragraphs explain how to limit the drivers, and give an
        example which can be be reduced or amended as necessary.
      </para>
    </note>

    <para>
      Now, select the drivers you wish to install. For the X86 architecture, the
      available gallium drivers are auto, <emphasis>or alternatively a choice
      from</emphasis> i915, nouveau, r300, r600, radeonsi, svga, swrast, and
      virgl. The latter is recommended if you intend to run the system under
      <xref linkend="qemu"/>. If you wish to build all available gallium drivers,
      use 'auto'.
    </para>

    <para>
      The (non-gallium) DRI drivers available in X86 are auto, <emphasis>or
      alternatively a choice from</emphasis> i915, i965, nouveau, r100, r200,
      and swrast. Use 'auto' to build all available DRI drivers, or use an
      empty string (DRI_DRIVERS="") if you wish to only build gallium drivers.
    </para>

    <para>
      The platforms ("window systems") available for X86 linux are x11, wayland,
      drm, and surfaceless. By not specifying anything, the meson build-system
      will build for all these platforms if you have the dependencies, identical
      to if you had specified '-Dplatforms=auto'.
    </para>

    <para>
      Modify the commands below for your desired drivers.  The drivers listed
      below will cover most modern video cards and virtual machines.  For help in
      selecting drivers see <ulink url='http://www.mesa3d.org/systems.html'/>.
    </para>

    <note>
      <para>
        Although the nouveau drivers can be built for both gallium and dri, the
        i915 driver can only be built for one or the other.
      </para>

    <!-- The iris driver has been temporarily removed from the below line.
         With mesa-20.0.5, it caused crashes and occasional system lockups.
         Exporting MESA_LOADER_DRIVER_OVERRIDE=i965 was able to fix it on
         my Skylake (i5-6600k) system, but that overrides the iris driver.
         Let's revisit this at a later time, maybe in a few releases or when
         the hardware is more accessible. See 
         http://lists.linuxfromscratch.org/pipermail/blfs-dev/2020-April/037385.html
