NAME

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

SYNOPSIS

DESCRIPTION

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:

On R6xx and R7xx based cards: NO support for hardware-based 2D & 3D acceleration, no support for Xvideo.
No TV and Component connector support so far.
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, sometimes 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.

CONFIGURATION DETAILS

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 better 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 (R5xx and RS6xx chips only for the moment). Currently, the default is off.
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.i
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 in case the panel resolution is lower than the one of the external display.
scale
means to always scale to the resolution of the external display filling the entire panel.
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.
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 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 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 difficulties.
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 commas) 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 considered to be more flexible.
Option "HPD" "auto|off|normal|swap"
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.
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 Auto.
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, 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 off.
Option "HDMI" "boolean"
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 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 <output_transmitter>=on|off. Possible values for <output_transmitter> 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.
NTSC
NTSCJ
PAL
PALM
PALCN
PALN
PAL60
SECAM
CV
Composite Video

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

RANDR OUTPUT PROPERTIES

The following properties can be queried with xrandr --prop and some of them can be set with xrandr --output <output> --set <property> <value> . Those marked with RR13 will be merged into a RandR 1.3 standard, though substantially changed. Properties marked Read-Only are provided by the driver for informational purpose only, those marked Static won't change during runtime.
RANDR_SIGNAL_FORMAT Read-Only RR13
Type: string
Range/List:
unknown VGA TMDS LVDS FBAS FBAS-PAL FBAS-NTSC FBAS-SECAM SVideo YPbPr DisplayPort

Signal format / physical protocol format that is used for the specified output.
A driver MAY change this property of an output if the underlying hardware indicates a protocol change (e.g. TV formats). Values with dashes (FBAS-PAL) describe more specific versions of the base values (FBAS) and SHOULD be used if known to the driver.
RANDR_CONNECTOR_TYPE Read-Only Static RR13
Type: string
Range/List:
unknown VGA DVI DVI-I DVI-A DVI-D HDMI PANEL TV TV-FBAS TV-SVideo TV-YPbPr TV-SCART TV-C4 DisplayPort

Connector type, as far as known to the driver.
Values with dashes (TV-FBAS) describe more specific versions of the base values (TV). The former SHOULD be used if the connector is not capable of producing other signal formats. The later SHOULD be used if the exact connector is unknown, or the connector is a multi-format connector that is not described otherwise. DVI, for instance, SHOULD be handled like a DVI-I connector, unless additional information is available to the user agent. PANEL describes laptop-internal (normally LVDS) displays. TV, TV-SCART, TV-YPbPr, and TV-C4 with signal format VGA are valid combinations and describe RGB TV signals.
RANDR_CONNECTOR_NUMBER Read-Only Static RR13
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. 1 is called the primary connector, 2 the secondary. 3 is often a TV connector, but that is completely driver / hardware dependent.
Outputs with the same connector number SHOULD have the same connector type. Meaning and client behavior for mismatching connector types is undefined at the moment.
RANDR_OUTPUT_NUMBER Read-Only Static RR13
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 continue as gracefully as possible if using different Crtcs for the same internal output is requested.
Internal outputs are numbered from 1, 0 indicates that output routing is unknown.
RANDR_PANNING_AREA
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.

KNOWN BUGS

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
 https://bugs.freedesktop.org/query.cgi?product=xorg&component=Driver/radeonhd
 
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 explicitly selecting them with --crtc [0|1] on the xrandr(1) command line.
