.SH DESCRIPTION
.B radeonhd
is an __xservername__ driver for AMD GPG (ATI) R5xx/R6xx/R7xx based video cards.

At the time of this writing,
.B radeonhd
has the following limitations:
.\".TP "\w'\fB\(bu\fR'u+1n"
.TP 2
\(bu
On R6xx and R7xx based cards:
.B NO
support for hardware-based 2D & 3D acceleration, no support for Xvideo.
.TP
\(bu
No TV and Component connector support so far.
.TP
\(bu
After using the
.I fglrx
driver,
.B radeonhd
might fail to work properly. This combination is not and probably will never be
supported.  A reboot fixes problems in most cases, sometimes a powercycle is
necessary.  Unloading the kernel module is typically not enough.

.SH CONFIGURATION DETAILS
Please refer to __xconfigfile__(__filemansuffix__) for general
configuration details.
.P
This section only covers configuration options
specific to this driver, for
.BR "Section \*qDevice\*q" .
Some options may be deprecated and considered to be
removed or replaced by better implementations soon.
.\"
.TP
.BI "Option \*qAccelMethod\*q \*q" none|default|shadowfb|xaa|exa \*q
Use the indicated accleration method.
.RS
.TP 9
.PD 0
.B none
does not accelerate anything at all. Discouraged.
.TP
.B shadowfb
is a software-only acceleration technique. Does not work together with
DRI at the moment.
.TP
.B xaa
is the older but stable hardware-based acceleration technique.
.TP
.B exa
is the newer but more experimental hardware-based acceleration technique.
.RE
.RS
.PD
.PP
The default is
.BR "depending on the chipset" ,
driver version, and state of acceleration techniques and tries to give the best
user experience.
.br
Rotation isn't supported for the AccelMethods \*qnone\*q and \*qshadowfb\*q.
.RE
.TP
.BI "Option \*qDRI\*q"
Use this option to enable 3D and Xv acceleration using DRI
(R5xx and RS6xx chips only for the moment).
Currently, the default is
.BR off .
.TP
.BI "Option \*qOffscreenSize\*q \*q" <integer>M|<integer>% \*q
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
.BR 10% .
.TP
.BI "Option \*qScaleType\*q \*q" none|center|scale|scale_keep_aspect_ratio|default \*q
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.i
.RS
.TP 9
.PD 0
.B 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.
.TP
.B center
means not to scale but center the image on the panel i.e. apply a black frame
around the image on the panel in case the panel resolution is lower than the
one of the external display.
.TP
.B scale
means to always scale to the resolution of the external display filling
the entire panel.
.TP
.B scale_keep_aspect_ratio
scales the panel display but keeps the aspect ratio of the external display,
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.
.TP
.B default
keeps the aspect ratio, but does not to scale otherwise.
.RE
.RS
.PD
.PP
The
.B default
is to keep the aspect ratio.
.RE
.TP
.BI "Option \*qNoRandr\*q
Disable RandR 1.2 support. This turns the driver back to use standard
modesetting behavior. The default is to
.B enable
RandR 1.2 support.
.TP
.BI "Option \*qSWcursor\*q \*q" boolean \*q
Enable or disable the software cursor. The hardware cursor is inactive
when the software cursor is enabled. The default is
.BR off .
.TP
.BI "Option \*qForceReduced\*q \*q" boolean \*q
Force the use of reduced blanking modes. Use this if your LCD monitor does not
provide correct EDID data and you need a reduced blanking mode to drive a high
resolution mode over a single link DVI connection. The default is
.BR off .
.TP
.BI "Option \*qUnverifiedFeatures\*q \*q" boolean \*q
The
.B radeonhd
driver sometimes relies on unverified graphics card features. You can add
.B "Option \*qUnverifiedFeatures\*q \*qoff\*q"
to disable those when you run into difficulties.
.TP
.BI "Option \*qRROutputOrder\*q \*q" "list-of-outputs" \*q
.IR "RandR modesetting only" .
.br
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 commas) to the
.IR list-of-outputs .
Typically only the first (primary) output has to be listed, remaining
outputs are added automatically. The default is
.BR none .
.TP
.BI "Option \*qIgnoreConnector\*q \*q" string \*q
.IR "Standard (non-RandR) modesetting only" .
.br
Connector to be ignored during non-RandR modesetting. The default is
.BR none .
.TP
.BI "Option \*qUseConfiguredMonitor\*q \*q" boolean \*q
.IR "Standard (non-RandR) modesetting only" .
.br
Use or ignore the monitor section in
.IR xorg.conf .
In standard modesetting
.B 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
.B off
(i.e. ignore).
.TP
.BI "Option \*qNoAccel\*q
Disable all hardware acceleration. The default is to
.B enable
hardware acceleration.

.RS
.B NOTE:
Use of this option is considered deprecated. The
.B AccelMethod
option is considered to be more flexible.
.RE
.TP
.BI "Option \*qHPD\*q \*q" "auto|off|normal|swap" \*q
Change the use of the hot plug detection (HPD) pins. On R5xx the according
connector tables are often broken and have to be worked around.
.RS
.TP 8
.PD 0
.B Auto
Select method depending on chipset and board
.TP
.B Off
Don't use HPD pins. Some connectors might not be able to detect connections
at all
.TP
.B Normal

.TP
.B Swap
Swap HPD pin 1 and 2 in connector table
.RE
.RS

.B 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
.BR Auto .
.RE
.TP
.BI "Option \*qForceDPI\*q \*q" integer \*q
Force the use of the specified pixel density in Dots Per Inch.
The default is
.BR "to use the monitor supplied values" .
.PP
.RS
.B NOTE:
Use of this option is discouraged. Monitors should return valid DPI values,
and the Xserver should honour them correctly.
.RE
.TP
.BI "Option \*qUseAtomBIOS\*q \*q" boolean \*q
Selects the mode setting path. The default is
.BR "chipset dependent" .
.PP
.RS
.B 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.
.RE
.TP
.BI "Option \*qAudio\*q \*q" boolean \*q
This option enables the audio hardware, wich 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
.BR off .
.TP
.BI "Option \*qHDMI\*q \*q" boolean \*q
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).
.TP
.BI "Option \*qCoherent\*q \*q" string \*q
There are two different ways to program the TMDS encoder in an output
for best signal 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
.B <output_transmitter>=on|off. 
Possible  values for 
.B <output_transmitter> 
are: 
.B TMDS_A, 
.B TMDS_B,
.B UNIPHY_A,
.B UNIPHY_B,
.B AtomOutputTMDSA,
.B AtomOutputLVTMA,
.B AtomOutputKldskpLvtma,
.B AtomOutputUniphyA,
.B  AtomOutputUniphyB. 
The log file should be consulted 
on which ones to use. The line:
.B "Option \*qCoherent\*q \*qTMDS_A=off TMDS_B=on\*q"
will set coherent mode to 
.B off 
for TMDS A and to 
.B on 
for TMDS B.
The default for all outputs is
.BR off .

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

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

application typically always resets the framebuffer size with every action,
.BR --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.

Use of this option is considered deprecated.  The driver supports
.B RandR 1.3
panning, which is included in Xserver 1.6.  It is considerable more flexible,

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