    <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>in 21.2.1 this does not select
      crocus </emphasis>), <emphasis>or alternatively a choice from</emphasis>
      crocus, i915, iris, nouveau, r300, r600, radeonsi, svga, swrast, and virgl.
      The latter can provide acceleration in <xref linkend="qemu"/> if that has
      been linked against
      <ulink url="https://gitlab.freedesktop.org/virgl/virglrenderer/~/releases/">virglrenderer</ulink>
      (you will need a freedesktop.org account to get to that page, you can
      download the 0.9.1 release without an account from
     <ulink url="https://gitlab.freedesktop.org/virgl/virglrenderer/-/archive/0.9.1/virglrenderer-0.9.1.tar.bz2">virglrenderer-0.9.1</ulink>).-->

<!-- If you wish to build all available gallium drivers,
      use 'auto'. FIXME : does not build crocus in 21.2.1 -->

      <!-- crocus was added to the default x86/x86_64 drivers for meson in the
      master branch on 2021-08-31, at some point it will appear in a stable release

-->
<!--
    <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="https://docs.mesa3d.org/systems.html"/>.
-->
      <!-- these two don't seem to be mentioned in that mesa link -->
<!--
      For intel drivers, specify crocus for i965 gen 4 through to haswell, iris
      for broadwell and later.
    </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>
      <parameter>--buildtype=release</parameter>: This switch ensures a
      fully-optimized build, and disables debug assertions which will
      severely slow down the libraries in certain use-cases. Without this
      switch, build sizes can span into the 2GB range.
    </para>

      controls which Gallium3D drivers should be built.

<!--
    <para>
      <parameter>-Dosmesa=true</parameter>: This switch enables building
      the <filename class="libraryfile">libOSMesa</filename> library and
      provides Gallium3D support in it. It requires the swrast gallium driver.
    </para>
-->

    <para>
      <parameter>-Dplatforms="..."</parameter>: This parameter
      controls which windowing systems will be supported. Available
      linux platforms are x11 and wayland.
    </para>

    <para>
      <parameter>-Dvulkan-drivers=""</parameter>: This switch allows choosing
      which Vulkan drivers are built. The default is auto, but this requires
      the optional dependency <filename>glslang</filename>. So it is better
      to pass an empty list, in order to remove the need for that
      dependency.  Nothing in BLFS uses Vulkan anyway.
    </para>

    <para>
      <parameter>-Dvalgrind=disabled</parameter>: This parameter disables
      the usage of Valgrind during the build process. Remove this parameter
      if you have Valgrind installed, and wish to check for memory leaks.
    </para>

    <para>
      <parameter>-Dlibunwind=disabled</parameter>: This parameter disables
      the usage of libunwind.
    </para>

      <command>meson configure -Dbuild-tests=true</command>: This command will
      reconfigure the build to set <option>-Dbuild-tests=true</option>, but
      keep the other options specified in the <command>meson setup</command>
      command unchanged.  It allows <command>ninja test</command> to build and
      run unit tests.
    </para>

    <para>
      <option>-Degl-native-platform="..."</option>: This parameter
      controls which Embedded Graphics Library support will be built. Available
