Section "Device" Identifier "devname" Driver "radeon" ... EndSection
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 accelera- tion, hardware 3D acceleration (except R300 and IGP series cards), hardware cursor, XV extension, Xinerama extension.
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) (2D only) RV200 Radeon 7500, M7, FireGL 7800 RS200 Radeon IGP330(M)/IGP340(M) (2D only) RS250 Radeon Mobility 7000 IGP (2D only) R200 Radeon 8500, 9100, FireGL 8800/8700 RV250 Radeon 9000PRO/9000, M9 RS300 Radeon 9100 IGP (2D only) RV280 Radeon 9200PRO/9200/9200SE, M9+ R300 Radeon 9700PRO/9700/9500PRO/9500/9600TX, FireGL X1/Z1 (2D only) R350 Radeon 9800PRO/9800SE/9800, FireGL X2 (2D only) R360 Radeon 9800XT (2d only) RV350 Radeon 9600PRO/9600SE/9600, M10/M11, FireGL T2 (2D only) RV360 Radeon 9600XT (2d only) XFree86 Version 4.5.0 1 RADEON(4) UNIX Programmer's Manual RADEON(4)
Please refer to XF86Config(5) 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 com- ponent 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 0x1E. Option "UseFBDev" "boolean" 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 "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. XFree86 Version 4.5.0 2 RADEON(4) UNIX Programmer's Manual RADEON(4) Option "BusType" "string" Used to replace previous ForcePCIMode option. Should only be used when driver's bus detection is incorrect or you want to force a AGP card to PCI mode. Should NEVER force a PCI card to AGP bus. PCI -- PCI bus AGP -- AGP bus PCIE -- PCI Express (falls back to PCI at present) (used only when DRI is enabled) The default is auto detect. Option "ForcePCIMode" "boolean" Force to use PCI GART for DRI acceleration. This option is deprecated in favor of the BusType option above and will be removed in the next release. Option "DDCMode" "boolean" Force to use the modes queried from the connected moni- tor. The default is off. Option "DisplayPriority" "string" Used to prevent flickering or tearing problem caused by display buffer underflow. AUTO -- Driver calculated (default). BIOS -- Remain unchanged from BIOS setting. Use this if the calculation is not correct for your card. HIGH -- Force to the highest priority. Use this if you have problem with above options. This may affect performence slightly. The default value is AUTO. Option "MonitorLayout" "string" 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 -- Laptop 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 XFree86 Version 4.5.0 3 RADEON(4) UNIX Programmer's Manual RADEON(4) 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 "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. For example, Option "CloneMode" "1024x768" The default value is undefined. Option "CloneHSync" "string" Set the horizontal sync range for the secondary moni- tor. 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 "CloneVRefresh" "string" Set the vertical refresh range for the secondary moni- tor. 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 "OverlayOnCRTC2" "boolean" Force hardware overlay to clone head. The default value is off. Option "IgnoreEDID" "boolean" 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 "PanelSize" "string" Should only be used when driver cannot detect the correct panel size. Apply to both desktop (TMDS) and laptop (LVDS) digital panels. When a valid panel size is specified, the timings collected from DDC and BIOS will not be used. If you have a panel with timings dif- ferent from that of a standard VESA mode, you have to provide this information through the Modeline. For example, Option "PanelSize" "1400x1050" The default value is none. XFree86 Version 4.5.0 4 RADEON(4) UNIX Programmer's Manual RADEON(4) 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 "ForceMinDotClock" "frequency" Override minimum dot clock. Some Radeon BIOSes report a minimum dot clock unsuitable (too high) for use with television sets even when they actually can produce lower dot clocks. If this is the case you can override the value here. Note that using this option may You have been warned. The frequency parameter may be speci- fied as a float value with standard suffixes like "k", "kHz", "M", "MHz". Option "iBookHacks" "boolean" On some iBook models the screen is distorted and exit- ing the X server does not reset the console properly. This option enables a workaround for these problems. The default is off.
