RADEON(4x) RADEON(4x)
NAME
radeon - ATI RADEON video driver
SYNOPSIS
Section "Device"
Identifier "devname"
Driver "radeon"
...
EndSection
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 exten-
sion.
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
RV200 Radeon 7500, M7
R200 Radeon 8500, 9100, FireGL 8800/8700
RV250 Radeon 9000, M9
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 "SWcursor" "boolean"
Selects software cursor. The default is off.
Option "NoAccel" "boolean"
Enables or disables all hardware acceleration.
The default is to enable hardware acceleration.
Option "Dac6Bit" "boolean"
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 "VideoKey" "integer"
This overrides the default pixel value for the YUV video overlay key.
The default value is undefined.
Option "UseFBDev" "boolean"
Enable or disable use of an OS-specific framebuffer device interface (which is not supported on all OSs). See fbdevhw(4x) for fur-
ther information.
The default is off.
Option "AGPMode" "integer"
Set AGP data transfer rate. (used only when DRI is enabled)
1 -- x1 (default)
2 -- x2
4 -- x4
others -- invalid
Option "AGPFastWrite" "boolean"
Enable AGP fast write.
(used only when DRI is enabled)
The default is off.
Option "ForcePCIMode" "boolean"
Force to use PCI GART for DRI acceleration.
(used only when DRI is enabled)
The default is off.
Option "DDCMode" "boolean"
Force to use the modes queried from the connected monitor.
The default is off.
Option "CloneDisplay" "integer"
This option is only used for dual-head cards with only single screen section specified in the configuration file.
0 -- disable
1 -- auto-detect (default)
2 -- force on
3 -- auto-detect + 2nd head overlay
4 -- force on + 2nd head overlay
others -- auto-detect
disable means only one CRTC is used for both heads. auto-detect means the secondary head will be driven by CRTC2 if a monitor is
detected there. force on means the secondary head will be driven by CRTC2 even no monitor is detected there. 2nd-head overlay
means the only hardware overlay will be placed to the secondary head.
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
Option "CloneMode" "string"
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.
Option "CloneHSync" "string"
Set the horizontal sync range for the secondary monitor. It is not required if a DDC-capable monitor is connected.
The default value is undefined.
Option "CloneVRefresh" "string"
Set the vertical refresh range for the secondary monitor. It is not required if a DDC-capable monitor is connected.
The default value is undefined.
Option "PanelOff" "boolean"
Disable panel output. Only used when clone is enabled.
The default value is off.
Option "EnablePageFlip" "boolean"
Enable page flipping for 3D acceleration. This will increase performance but not work correctly in some rare cases, hence the
default is off.
Option "ForceLegacyCRT" "boolean"
Enable usage of legacy VGA CRT display when no monitor is detected. This can be used to force the driver to work with ancient VGA
monitors, such as an old mono VGA monitor. Plugging 2 monitors into a dualhead radeon card while using this option, may cause dam-
age to one or both monitors. off.
