radeon is a family of open source graphics drivers for AMD/ATI Radeon graphics cards.

Contents

Hardware detection

To choose the right driver, first detect the graphics card. You can use lspci for this task:

root # lspci | grep -i VGA

Installation

Kernel

You need to activate the following kernel options:

Kernel configuration

Processor type and features  --->
    [*] MTRR (Memory Type Range Register) support
Device Drivers  --->
    Graphics support  --->

        If your card sits in an AGP slot, choose your AGP driver, e.g.:
        <*> /dev/agpgart (AGP Support)  --->
            <*> AMD Opteron/Athlon64 on-CPU GART support

        <*> Direct Rendering Manager (XFree86 4.1.0 and higher DRI support) --->
            <*> ATI Radeon
            [*] Enable modesetting on radeon by default

Firmware

There is IRQ microcode for R600 and newer GPUs. Install either x11-drivers/radeon-ucode or sys-kernel/linux-firmware (contains also other firmware):

root # emerge --ask radeon-ucode
root # emerge --ask linux-firmware

Make sure firmware for your model (check available ones in /lib/firmware/radeon) is included in kernel:

Kernel configuration

Device Drivers  --->
    Generic Driver Options  --->
        -*- Userspace firmware loading support
        [*] Include in-kernel firmware blobs in kernel binary
            (radeon/<YOUR-MODEL>.bin)
            (/lib/firmware) Firmware blobs root directory

Below is a list of the firmware files needed for each family of cards:

Driver

Portage uses the variable VIDEO_CARDS for enabling support for various graphics cards in packages. Setting VIDEO_CARDS to e.g. radeon (see the feature matrix) will pull in the correct driver:

File/etc/portage/make.conf

VIDEO_CARDS="radeon"

Check the USE flags of x11-drivers/xf86-video-ati:

→ Information about USE flags
USE flag Default Recommended Description
glamor No (For Northern Islands and older cards) Enable Glamor OpenGL 2D acceleration
glamor No Yes (For Southern Islands and newer cards) Enable Glamor OpenGL 2D acceleration
udev Yes Yes Enable sys-fs/udev integration (device discovery, power and storage device support, etc)

After setting this you want to update your system so the changes take effect:

root # emerge --ask --changed-use --deep @world

Configuration

Permissions

If you have the USE flag acl enabled globally and are using ConsoleKit (i.e you're using a Desktop profile) permissions to video cards will be handled automatically. You can check the permissions using getfacl:

user $ getfacl /dev/dri/card0 | grep larry
user:larry:rw-

A broader solution is to add the user you want to be able to access the video card to the video group:

root # gpasswd -a larry video

Note that you will still be able to run X without permission to the DRI subsystem, but usually not with acceleration enabled.

xorg.conf

The X server is designed to work out-of-the-box, with no need to manually edit X.Org's configuration files. It should detect and configure devices such as displays, keyboards, and mice.

However, the main configuration file of the X server is the xorg.conf.

You can force the X server to use desired driver with:

File/etc/X11/xorg.conf.d/radeon.confExplicit radeon driver section

 Section "Device"
   Identifier  "radeon"
   Driver      "radeon"
 EndSection

Advanced configuration

Power Management

Power management can be set in the sysfs filesystem as follows:

  • Check the current power method:
root # cat /sys/class/drm/card0/device/power_method
  • Change the power method:
The "dynpm" method dynamically changes the clocks based on demand. (not effective as of June 27, 2012)
root # echo "dynpm" > /sys/class/drm/card0/device/power_method
The "profile" method lets you set a profile on how the card should behave.
root # echo "profile" > /sys/class/drm/card0/device/power_method
  • Check the current profile:
root # cat /sys/class/drm/card0/device/power_profile
  • Change the profile:
Options for profile:
  1. "default" no change of clock speeds
  2. "auto" switches between "mid" and "high" power states based on the whether the system is on battery power or not. The "low" power state are selected when the monitors are in the dpms off state.
  3. "low" forces the GPU to be in the low power state all the time. Note that "low" can cause display problems on some laptops; this is why auto does not use "low" when displays are active.
  4. "mid" forces the GPU to be in the "mid" power state all the time. The "low" power state is selected when the monitors are in the dpms off state.
  5. "high" forces the GPU to be in the "high" power state all the time. The "low" power state is selected when the monitors are in the dpms off state.
root # echo "low" > /sys/class/drm/card0/device/power_profile
  • Check the current GPU, Memory clocks and voltage (needs to have kernel debugfs enabled):
root # cat /sys/kernel/debug/dri/0/radeon_pm_info
Note
With more than one monitor connected, the memory clock will always be on full speed.
Note
On APU chipsets, those settings have little to no effect and give inconclusive results.

Tuning

I couldn't find a summary of all options available so feel free to add to this.

Warning
There are several options to tweak the radeon driver and some of these might break your desktop, so if you are uncomfortable with the console better stick to default.
Parameter Application Effect
radeon.pcie_gen2=1 kernel commandline Run at PCI-E 2.0 speeds per default
radeon.audio=1 kernel commandline Enable HDMI audio on some cards
R600_STREAMOUT=1 Environment variable Enable the use of OpenGL 3.0/4.2 on some cards
R600_HYPERZ=1 Environment variable Enable the use Hyper-Z on some cards
R600_TILING=1 Environment variable Enable 2D Tiling on some cards (also needs the xorg.conf parameter set)
R600_SURF=1 Environment variable Enable 2D Tiling on some cards (also needs the xorg.conf parameter set)
R600_GLSL130=1 Environment variable Enable more features of the OpenGL 3.0 API
ColorTiling2D True xorg.conf parameter Enable 2D Color Tiling in conjunction with R600_TILING=1 and R600_SURF=1
  • Kernel parameters can be just added to the kernel commandline in grub.cfg or grub.conf.
  • Environment variables could be put into a file like /etc/env.d/99radeon to have them initialized during boot.
  • xorg.conf parameter are usual in the Device section for the card.
  • A full list of kernel parameters can be found here: X.Org Wiki - RadeonFeature
  • S3TC compression needed for some applications like most 3D games: media-libs/libtxc_dxtn

Monitoring

lm sensors can be used to monitor the cards temperature. It uses the I2C interface, which needs to be enabled in the kernel:

        <*> Support for frame buffer devices --->
            <*> ATI Radeon display support 
                [*] DDC/I2C for ATI Radeon support

Audio over HDMI

Audio through the HDMI port is available for some cards. Check the X.Org Wiki - Radeon Feature Matrix for the model family. A recent 3.x kernel may be needed.

As noted above, HDMI audio must be explicitly enabled using the kernel commandline paramater radeon.audio=1. In addition, ALSA typically does not use HDMI as the default audio, so one way to force this as the default is to add a config file:

File~/.asoundrc

pcm.!default {
  type plug
  slave.pcm "hdmi"
}

which may be moved to /etc/asound.conf to make HDMI audio the system-wide default.
