CONFIGURATION DETAILS

     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.

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.

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.
