      <para>
        The <application>Xorg AMDGPU Driver</application> package contains the X.Org
        Video Driver for newer AMD Radeon video cards starting from Volcanic Islands.
        It can also be used for Southern and Sea Islands if the experimental support
        was enabled in the kernel.

        <para>
          For Direct Rendering to work, you need to enable the radeonsi Gallium
          driver at <xref linkend="mesa"/> build time. Also, all 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-amdgpu-firmware-kernel"/> below for additional
          firmware.

      <para>
        The last two options enable experimental support for Southern and
        Sea Islands AMD GPUs so they can be used with this driver. Note that
        the support is marked experimental and disabled by default.
        <xref linkend="xorg-ati-driver"/> should be used for those GPUs.

        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. Below is an example for Radeon R7 M340 GPU, which is codenamed
        Iceland/Topaz, along with a network card that also requires the firmware:

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

      <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_AMDGPU to '=m' in your linux
        kernel .config the firmware can be loaded automatically from
        /lib/firmware/amdgpu/ 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.
