DESCRIPTION

radeon is a XFree86 driver for ATI RADEON based video cards. It contains full support for 8, 15, 16 and 24 bit pixel depths, dual-head setup, flat panel, hardware 2D acceleration, hardware 3D acceleration (except R300 cards), hardware cursor, XV extension, Xinerama extension.

SUPPORTED HARDWARE

The radeon driver supports PCI and AGP video cards based on the following ATI chips

R100: Radeon 7200
RV100: Radeon 7000(VE), M6
RS100: Radeon IGP320(M)
RV200: Radeon 7500, M7
RS200: Radeon IGP330(M)/IGP340(M)
R200: Radeon 8500, 9100, FireGL 8800/8700
RV250: Radeon 9000, M9
R280: Radeon 9200
R300: Radeon 9700PRO/9700/9500PRO/9500, FireGL X1/Z1

CONFIGURATION DETAILS

Please refer to XF86Config(5x) for general configuration details. This section only covers configuration details specific to this driver.

The driver auto-detects all device information necessary to initialize the card. However, if you have problems with auto-detection, you can specify:

: VideoRam - in kilobytes
MemBase - physical address of the linear framebuffer
IOBase - physical address of the MMIO registers
ChipID - PCI DEVICE ID

In addition, the following driver Options are supported:

Option N'34'SWcursorN'34' N'34'booleanN'34'

Selects software cursor. The default is off.

Option N'34'NoAccelN'34' N'34'booleanN'34'

Enables or disables all hardware acceleration.
The default is to enable hardware acceleration.

Option N'34'Dac6BitN'34' N'34'booleanN'34'

Enables or disables the use of 6 bits per color component when in 8 bpp mode (emulates VGA mode). By default, all 8 bits per color component are used.
The default is off.

Option N'34'VideoKeyN'34' N'34'integerN'34'

This overrides the default pixel value for the YUV video overlay key.
The default value is 0x1E.

Option N'34'UseFBDevN'34' N'34'booleanN'34'

Enable or disable use of an OS-specific framebuffer device interface (which is not supported on all OSs). See fbdevhw(4) for further information.
The default is off.

Option N'34'AGPModeN'34' N'34'integerN'34'

Set AGP data transfer rate. (used only when DRI is enabled)
1 -- x1 (default)
2 -- x2
4 -- x4
others -- invalid

Option N'34'AGPFastWriteN'34' N'34'booleanN'34'

Enable AGP fast write.
(used only when DRI is enabled)
The default is off.

Option N'34'ForcePCIModeN'34' N'34'booleanN'34'

Force to use PCI GART for DRI acceleration.
(used only when DRI is enabled)
The default is off.

Option N'34'DDCModeN'34' N'34'booleanN'34'

Force to use the modes queried from the connected monitor.
The default is off.

Option N'34'MonitorLayoutN'34' N'34'stringN'34'

This option is used to overwrite the detected monitor types. This is only required when driver makes a false detection. The possible monitor types are:
NONE -- Not connected
CRT -- Analog CRT monitor
TMDS -- Desktop flat panel
LVDS -- Lapto flat panel
This option can be used in following format:
Option "MonitorLayout" "[type on primary], [type on secondary]"
For example, Option "MonitorLayout" "CRT, TMDS"

Primary/Secondary head for dual-head cards:
(when only one port is used, it will be treated as the primary regardless)
Primary head:
DVI port on DVI+VGA cards
LCD output on laptops
Internal TMDS prot on DVI+DVI cards
Secondary head:
VGA port on DVI+VGA cards
VGA port on laptops
External TMDS port on DVI+DVI cards

The default value is undefined.

Option N'34'CloneModeN'34' N'34'stringN'34'

Set the first mode for the secondary head. It can be different from the modes used for the primary head. If you don't have this line while clone is on, the modes specified for the primary head will be used for the secondary head.
For example, Option "CloneMode" "1024x768"
The default value is undefined.

Option N'34'CloneHSyncN'34' N'34'stringN'34'

Set the horizontal sync range for the secondary monitor. It is not required if a DDC-capable monitor is connected.
For example, Option "CloneHSync" "30.0-86.0"
The default value is undefined.

Option N'34'CloneVRefreshN'34' N'34'stringN'34'

Set the vertical refresh range for the secondary monitor. It is not required if a DDC-capable monitor is connected.
For example, Option "CloneVRefresh" "50.0-120.0"
The default value is undefined.

Option N'34'OverlayOnCRTC2N'34' N'34'booleanN'34'

Force hardware overlay to clone head.
The default value is off.

Option N'34'IgnoreEDIDN'34' N'34'booleanN'34'

Do not use EDID data for mode validation, but DDC is still used for monitor detection. This is different from NoDDC option.
The default value is off.

Option N'34'PanelOffN'34' N'34'booleanN'34'

Disable panel output. Only used when clone is enabled.
The default value is off.

Option N'34'EnablePageFlipN'34' N'34'booleanN'34'

Enable page flipping for 3D acceleration. This will increase performance but not work correctly in some rare cases, hence the default is off.
