       radeonhd - AMD GPG (ATI) R5xx/R6xx/R7xx video driver

       Section "Device"
	 Identifier "devname"
	 Driver "radeonhd"

       radeonhd is an Xorg driver for AMD GPG (ATI) R5xx/R6xx/R7xx based video cards.

       At the time of this writing, radeonhd has the following limitations:

       o Support  for  hardware-based  2D  acceleration and Xvideo needs more testing on R6xx and
	 R7xx based cards.

       o No TV and Component connector support so far.

       o After using the fglrx driver, radeonhd might fail to work properly. This combination  is
	 not  and probably will never be supported.  A reboot fixes problems in most cases, some-
	 times a powercycle is necessary.  Unloading the kernel module is typically not enough.

       A more up-to-date list can be found on the wiki page.

       The radeonhd driver supports video cards based on the following ATI chips:

       Please refer to xorg.conf(5) for general configuration details.

       This section only covers configuration  options	specific  to  this  driver,  for  Section
       "Device".  Some options may be deprecated and considered to be removed or replaced by bet-
       ter implementations soon.

       Option "AccelMethod" "none|default|shadowfb|xaa|exa"
	      Use the indicated accleration method.

	      none     does not accelerate anything at all. Discouraged.
	      shadowfb is a software-only acceleration technique. Does not work together with DRI
		       at the moment.
	      xaa      is the older but stable hardware-based acceleration technique.
	      exa      is the newer but more experimental hardware-based acceleration technique.

	      The  default is depending on the chipset, driver version, and state of acceleration
	      techniques and tries to give the best user experience.
	      Rotation isn't supported for the AccelMethods "none" and "shadowfb".

       Option "DRI"
	      Use this option to enable 3D and Xv acceleration using DRI.  Currently, the default
	      is on on R5xx and RS6xx chips, and off on all others.

       Option "OffscreenSize" "<integer>M|<integer>%"
	      Specify  the  amount of framebuffer memory used for offscreen pixmaps, in megabytes
	      or percent of available memory. This amount of memory is	not  available	for  DRI.
	      Certain hardware and software limits apply. The default is 10%.

       Option "ScaleType" "none|center|scale|scale_keep_aspect_ratio|default"
	      Sets  the  scaling  mode for laptop flat panels when used together with an external
	      screen. The scaling engine is capable of scaling both up and down.

	      none     means to not scale at all, i.e. the image will be  displayed  in  the  top
		       left  corner  of  the  panel  if the resolution of the external display is
		       lower than the panel resolution.
	      center   means not to scale but center the image on the panel i.e.  apply  a  black
		       frame around the image on the panel if the resolution of the external dis-
		       play is lower than the panel resolution.
	      scale    means to always scale to the resolution of the  external  display  filling
		       the entire panel.
		       scales  the  panel display but keeps the aspect ratio of the external dis-
		       play, which means if the external display has  a  different  aspect  ratio
		       than  the  panel  it  black borders will be added to the top and bottom or
		       left and right.
	      default  keeps the aspect ratio, but does not to scale otherwise.

	      The default is to keep the aspect ratio.

       Option "NoRandr"
	      Disable RandR 1.2 support. This turns the driver back to use  standard  modesetting
	      behavior. The default is to enable RandR 1.2 support.

       Option "SWcursor" "boolean"
	      Enable  or  disable  the	software cursor. The hardware cursor is inactive when the
	      software cursor is enabled. The default is off.

       Option "ForceReduced" "boolean"
	      Force the use of reduced blanking modes. Use this if your LCD monitor does not pro-
	      vide correct EDID data and you need a reduced blanking mode to drive a high resolu-
	      tion mode over a single link DVI connection. The default is off.

       Option "UnverifiedFeatures" "boolean"
	      The radeonhd driver sometimes relies on unverified graphics card features. You  can
	      add  Option "UnverifiedFeatures" "off" to disable those when you run into difficul-

       Option "RROutputOrder" "list-of-outputs"
	      RandR modesetting only.
	      Several legacy application rely on the Xinerama extension to determine the  primary
	      screen.  RandR  returns  the viewport displayed on the first attached output of the
	      internal table as the first Xinerama screen.  If your outputs are  ordered  in  the
	      wrong  way, you can reorder them by adding their names (separated by spaces or com-
	      mas) to the list-of-outputs.  Typically only the first (primary) output has  to  be
	      listed, remaining outputs are added automatically. The default is none.

       Option "IgnoreConnector" "string"
	      Standard (non-RandR) modesetting only.
	      Connector to be ignored during non-RandR modesetting. The default is none.

       Option "UseConfiguredMonitor" "boolean"
	      Standard (non-RandR) modesetting only.
	      Use  or  ignore the monitor section in xorg.conf.  In standard modesetting radeonhd
	      ignores the EDID data if a monitor section is configured.   This	is  different  to
	      what  most drivers behave like and a common source of configuration problems.  Thus
	      the default is off (i.e. ignore).

       Option "NoAccel"
	      Disable all hardware acceleration. The default is to enable hardware acceleration.

	      NOTE: Use of this option is considered deprecated. The AccelMethod option  is  con-
	      sidered to be more flexible.

       Option "HPD" "auto|off|normal|swap"
	      Change  the use of the hot plug detection (HPD) pins. On R5xx the according connec-
	      tor tables are often broken and have to be worked around.

	      Auto    Select method depending on chipset and board
	      Off     Don't use HPD pins. Some connectors might not be able to detect connections
		      at all
	      Normal  Use connector table information as-is
	      Swap    Swap HPD pin 1 and 2 in connector table

	      NOTE:  Use  of this option is discouraged. Whenever this option is needed to detect
	      connected monitors correctly, please report to the mailing list.	 The  default  is

       Option "ForceDPI" "integer"
	      Force  the  use of the specified pixel density in Dots Per Inch.	The default is to
	      use the monitor supplied values.

	      NOTE: Use of this option is discouraged. Monitors should return valid  DPI  values,
	      and the Xserver should honour them correctly.

       Option "UseAtomBIOS" "boolean"
	      Selects the mode setting path. The default is chipset dependent.

	      NOTE:  Use  of this option is discouraged. The driver should select the right path.
	      If this option is needed to get your card working correctly, please report  to  the
	      mailing list.

       Option "Audio" "boolean"
	      This  option  enables the audio hardware, which is responsible for delivering audio
	      data to the different HDMI capable conntectors and used  to  communicate	with  the
	      audio driver of the operation system. The default is off.

       Option "HDMI" "string"
	      Possible	values	are  "DVI-I_0",  "DVI-I_1"..,"DVI-D_0","DVI-I_1",.., "all".  This
	      option enables HDMI-Audio and HDMI-Info packets on the specified	connector.   This
	      is the only way enabling HDMI at the moment, since decoding E-EDID data to check if
	      monitor supports HDMI is not implemented (yet).

       Option "Coherent" "string"
	      There are two different ways to program the TMDS encoder in an output for best sig-
	      nal quality for the transmitter chip used inside a digital monitor. This option may
	      be used to set the programming for each output individually. The string is a  space
	      separated list of <output_transmitter>=on|off.  Possible	values for <output_trans-
	      mitter> are: TMDS_A, TMDS_B, UNIPHY_A, UNIPHY_B, AtomOutputTMDSA,  AtomOutputLVTMA,
	      AtomOutputKldskpLvtma,  AtomOutputUniphyA,  AtomOutputUniphyB.  The log file should
	      be consulted on  which  ones  to	use.  The  line:  Option  "Coherent"  "TMDS_A=off
	      TMDS_B=on"  will	set  coherent  mode  to off for TMDS A and to on for TMDS B.  The
	      default for all outputs is off.

       Option "TVMode" "tv-mode"
	      The TV standard to use on the TV output.

	      CV      Composite Video

	      NOTE: This option isn't implemented yet and has no effect.

       The following properties can be queried with xrandr --prop and some of  them  can  be  set
       with  xrandr  --output  <output>  --set	<property>  <value> .  Those not starting with an
       underscore '_' are RandR 1.3 standard properties.  See the RandR 1.3 protocol  description
       for  more  details.    Properties marked Read-Only are provided by the driver for informa-
       tional purpose only, those marked Static won't change during runtime.

       SignalFormat   Read-Only

	      Type:	      string
	      Range/List:     unknown VGA TMDS LVDS DisplayPort

	      Signal format / physical protocol format that is used for the specified output.

       ConnectorType   Read-Only Static

	      Type:	      string
	      Range/List:     unknown VGA DVI DVI-I DVI-A DVI-D HDMI Panel DisplayPort

	      Connector type, as far as known to the  driver.	Panel  describes  laptop-internal
	      (normally LVDS) displays.

       ConnectorNumber	 Read-Only Static

	      Type:	      int32
	      Range/List:     0-

	      Outputs  that route their signal to the same connector MUST have the same connector
	      number. Outputs with the same connector number MUST route their signal to the  same
	      connector, except if it is 0, which indicates unknown connectivity.

       _OutputNumber   Read-Only Static

	      Type:	      int32
	      Range/List:     0-

	      A  card  may  route one internal output to several connectors.  Connectors that are
	      driven by the same output cannot be driven by different Crtcs  and  are  thus  only
	      allowed  to be used in clone mode. The driver SHOULD emit an error message and con-
	      tinue as gracefully as possible if using different Crtcs for the same internal out-
	      put is requested.
	      Internal outputs are numbered from 1, 0 indicates that output routing is unknown.


	      Type:	      string
	      Format:	      <width>x<height>[+<xoffset>+<yoffset>]

	      Specifies the panning area in RandR mode per output.
	      It  actually  is	a Crtc-specific property, but RandR doesn't support that yet.  As
	      the xrandr application typically always resets  the  framebuffer	size  with  every
	      action,  --fb <width>x<height> has to be added on every invocation, unless there is
	      an additional output configured that is using this size as its resolution.
	      This property cannot be changed when in a rotated mode.

	      NOTE: Use of this option is considered deprecated.  The driver supports  RandR  1.3
	      panning,	which  is included in Xserver 1.6.  It is considerable more flexible, and
	      should support rotated pans.


	      Type:	      int32
	      Range/List:     0-255

	      Specifies the backlight intensity on laptop panels, if controlable by the driver.


	      Type:	      int32
	      Range/List:     0-1

	      Sets the coherent flag for TMDS signals. See also Option Coherent.

       As the radeonhd driver is still in development, some non-obvious  things  might	not  work
       yet.  A	list  of  major  known bugs is maintained on the wiki.	Other places to check for
       known bugs and solutions are the bugtracker at
       and the mailing list archives at http://lists.opensuse.org/radeonhd/

       radeonhd development caused a few bugs in Xorg and a number of bugs  in	xrandr(1)  to  be
       discovered.  If	you  are  using  xrandr(1) versions older than 2007-11-10, you should try
       updating xrandr(1).
       Alternatively, you can try to always specify different CRTCs for all monitors  by  explic-
       itly selecting them with --crtc [0|1] on the xrandr(1) command line.
