        The <application>Xorg ATI Driver</application> package contains the X.Org
        Video Driver for ATI Radeon video cards including all chipsets ranging
        from R100 to the "Volcanic Islands" chipsets.

      <note>
        <para>
          For Direct Rendering to work with newer Radeon Cards (R300 and later
          chipsets), you need to enable the r300, r600 and radeonsi Gallium
          drivers at <xref linkend="mesa"/> build time. Also, some cards
          require Firmware to be available when the kernel driver is loaded.
          Firmware can be obtained from <ulink
          url="&sources-anduin-http;/linux-firmware/"/>.
          See <xref linkend="xorg-ati-firmware-kernel"/> below for additional
          firmware.

      <para>
        If you need to add firmware, install the file(s) and then point to them in the
        kernel configuration and recompile the kernel if necessary. To find out which
        firmware you need, consult the <ulink url="&radeon-marketing-names;">
        Decoder ring for engineering vs marketing names</ulink>. Download any firmware
        for your card which is named like:
        <filename><replaceable>&lt;ENGINEERING_NAME&gt;</replaceable>_rlc.bin</filename>,
        etc. Note that for R600 and R700 family, generic
        <filename>R600_rlc.bin</filename> and <filename>R700_rlc.bin</filename> are
        necessary in addition to the model specific firmware, while for later generations
        you need the
        <filename>BTC_rlc.bin</filename> in addition to the model specific firmware.
        Below is an example for a Radeon HD6470 which is a "Northern Islands" GPU,
        plus an RTL network chip that also requests extra firmware:

CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware"</literal></screen>

     <note>
       <para>
         CONFIG_EXTRA_FIRMWARE should all be on one line.  It
         is shown above as two lines for presentation only.
       </para>
     </note>

      <tip>
        <para>
          You can check <command>dmesg</command> output after boot to see which firmware
          is missing.
        </para>
      </tip>

      <para>
        Alternatively, if you change CONFIG_DRM_RADEON to '=m' in your .config
        the firmware can be loaded automatically from /lib/firmware/radeon when
        it installs the module. This offers a tiny space saving, but also means
        that the screen will be blank for a longer time before the framebuffer
        appears. Distros take this approach because it is not practical to
        specify every possible firmware and the kernel would be excessively big.

      <title>Glamor Acceleration</title>

      <para>
        Glamor is an acceleration library which uses cards' 3D capabilities
        to accelerate 2D rendering. Glamor acceleration is either required
        or used by default for all R600 and later GPUs. To see which GPUs are
        in these categories, read the <ulink url="&radeon-marketing-names;">
        Decoder ring for engineering vs marketing names</ulink>.
      </para>

      <para>
        Please note
        that Glamor acceleration can be used with other chips as well, from the
        R300 onwards. On at least some Northern Islands chips it is beneficial.
      </para>

      <para>
        Glamor acceleration is not enabled by default for chipsets that don't
        use "radeonsi" Gallium3D driver. You have to use an
        <filename>xorg.conf</filename> file to enable it. To enable
        Glamor for cards other than "Southern Islands" and later, create the
        following file in
        <filename class="directory">${XORG_PREFIX}/share/X11/xorg.conf.d/</filename>
