       radeon is an Xorg driver	for ATI	RADEON-based video cards with the fol-
       lowing features:

       o Full support for 8-, 15-, 16- and 24-bit pixel	depths;
       o RandR 1.2 and RandR 1.3 support;
       o TV-out	support	(only on RV/RS1xx, RV/RS2xx, R/RV/RS3xx.  Experimental
	 support  on  R/RV5xx,	R/RV6xx,  and  R/RV7xx	through	 the ATOMTvOut
	 option);  TV-out is not supported on cards that use the Rage  Theatre
	 chip for TV-out (R100,	R200).
       o Full EXA 2D acceleration;
       o Full XAA 2D acceleration (only	on R/RV/RS1xx, R/RV/RS2xx, R/RV/RS3xx,
	 R/RV/RS4xx, R/RV5xx, RS6xx. XAA Render	acceleration supported only on
	 R/RV100, R/RV/RS2xx and RS3xx);
       o Textured  XVideo acceleration including anti-tearing support (Bicubic
	 filtering  only  available  on	 R/RV3xx,  R/RV/RS4xx,	R/RV5xx,   and
       o Overlay   XVideo   acceleration   (only  on  R/RV/RS1xx,  R/RV/RS2xx,
	 R/RV/RS3xx, R/RV/RS4xx);
       o 3D acceleration;

       Please refer to xorg.conf(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 for UMS (Userspace Modesetting):

	   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 for both UMS
       (Userspace Modesetting) and KMS (Kernel Modesetting):

       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 "ZaphodHeads" "string"
	      Specify the RandR	output(s) to use with zaphod mode for  a  par-
	      ticular  driver  instance.   If you use this option you must use
	      this option for all instances of the driver.
	      For  example:  Option  "ZaphodHeads"  "LVDS,VGA-0"  will	assign
	      xrandr outputs LVDS and VGA-0 to this instance of	the driver.

       Option "EXAVSync" "boolean"
	      This  option  attempts  to  avoid	tearing	by stalling the	engine
	      until the	display	controller has passed the destination  region.
	      It reduces tearing at the	cost of	performance and	has been known
	      to cause instability on some chips.  The default is off.

       The following driver Options are	supported  for	KMS  (Kernel  Modeset-

       Option "ColorTiling" "boolean"
	      The framebuffer can be addressed either in linear	or tiled mode.
	      Tiled mode can provide significant performance benefits with  3D
	      applications.   Tiling will be disabled if the drm module	is too
	      old or if	the current display configuration does not support it.
	      On R600+ this enables 1D tiling mode.
	      The  default  value  is on for R/RV3XX, R/RV4XX, R/RV5XX,	RS6XX,
	      RS740, R/RV6XX, R/RV7XX, RS780, RS880, EVERGREEN,	and CAYMAN and
	      off for R/RV/RS1XX, R/RV/RS2XX, and RS3XX.

       Option "ColorTiling2D" "boolean"
	      The  framebuffer	can  be	 addressed either in linear, 1D, or 2D
	      tiled modes. 2D tiled mode can provide  significant  performance
	      benefits	over  1D  tiling with 3D applications.	Tiling will be
	      disabled if the drm module is too	old or if the current  display
	      configuration  does  not	support	 it. KMS ColorTiling2D is only
	      supported	on R600	and newer chips.
	      The default value	is off for  R/RV6XX,  R/RV7XX,	RS780,	RS880,

       Option "EXAPixmaps" "boolean"
	      Under KMS, to avoid thrashing pixmaps in/out of VRAM on low mem-
	      ory cards, we use	a heuristic based on VRAM amount to  determine
	      whether  to  allow  EXA  to  use VRAM for	non-essential pixmaps.
	      This option allows us to override	the heuristic.	The default is
	      on with >	32MB VRAM, off with < 32MB.

       Option "SwapbuffersWait"	"boolean"
	      This option controls the behavior	of glXSwapBuffers and glXCopy-
	      SubBufferMESA calls by GL	applications.  If enabled,  the	 calls
	      will  avoid  tearing by making sure the display scanline is out-
	      side of the area to be copied before the copy occurs.   If  dis-
	      abled, no	scanline synchronization is performed, meaning tearing
	      will likely occur.  Note that  when  enabled,  this  option  can
	      adversely	 affect	 the  framerate	 of  applications  that	render
	      frames at	less than refresh rate.

	      The default value	is on.

       Option "EnablePageFlip" "boolean"
	      Enable DRI2 page flipping.  The default is on.  Pageflipping  is
	      supported	on all radeon hardware.

       The  following driver Options are supported for UMS (Userspace Modeset-

       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
	      The default value	is 0x1E.

       Option "ScalerWidth" "integer"
	      This sets	the overlay scaler buffer width. Accepted values range
	      from 1024	to 2048, divisible by 64.  Values other	than 1536  and
	      1920  may	not make sense.	 This should be	set automatically, but
	      no one knows what	the limit is for  which	 chip.	If  you	 think
	      quality is not optimal when playing back HD video	(with horizon-
	      tal resolution larger than this setting),	increase  this	value.
	      If  you  get an empty area at the	right (usually pink), decrease
	      it. Note that this only affects the "true" overlay via  Xv,  and
	      won't affect things like textured	video.
	      The default value	is either 1536 (for most chips)	or 1920.

       Option "AGPMode"	"integer"
	      Set AGP data transfer rate.  (used only when DRI is enabled)
	      1	     --	1x (before AGP v3 only)
	      2	     --	2x (before AGP v3 only)
	      4	     --	4x
	      8	     --	8x (AGP	v3 only)
	      others --	invalid
	      The default is to	leave it unchanged.

       Option "AGPFastWrite" "boolean"
	      Enable  AGP  fast	writes.	 Enabling this is frequently the cause
	      of instability. Used only	when the DRI is	enabled. If you	enable
	      this option you will get *NO* support from developers.
	      The default is off.

       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 an AGP card	to PCI mode. You should	NEVER force a PCI card
	      to AGP bus.
	      PCI    --	PCI bus
	      AGP    --	AGP bus
	      PCIE   --	PCI Express bus
	      (used only when DRI is enabled)
	      The default is auto detect.

       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	performance slightly.
	      The default value	is AUTO.

       Option "ColorTiling" "boolean"
	      The framebuffer can be addressed either in linear	or tiled mode.
	      Tiled mode can provide significant performance benefits with  3D
	      applications.   For  2D it shouldn't matter much.	Tiling will be
	      disabled if the virtual x	resolution exceeds 2048	(3968 for R300
	      and  above), or if DRI is	enabled	and the	drm module is too old.
	      If this option is	enabled, a new	DRI  driver  is	 required  for
	      direct rendering.
	      Color  tiling  will  be  automatically disabled in interlaced or
	      doublescan screen	modes.
	      The default value	is on.

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

       Option "CustomEDID" "string"
	      Forces  the  X  driver  to use the EDID data specified in	a file
	      rather than the  display's  EDID.	 Also  overrides  DDC  monitor
	      You  may	specify	 a semicolon-separated list of output name and
	      filename pairs with an optional flag, "digital" or "analog",  to
	      override the digital bit in the EDID which is used by the	driver
	      to determine whether to use the analog or	digital	encoder	 asso-
	      ciated  with  a DVI-I port.  The output name is the RandR	output
	      name, e.g., "VGA-0" or "DVI-0"; consult the  Xorg	 log  for  the
	      supported	output names of	any given system.
	      The  file	must contain a raw 128-byte EDID block,	as captured by
	      For   example:   Option	"CustomEDID"	"VGA-0:/tmp/edid1.bin;
	      DVI-0:/tmp/edid2.bin:digital" will assign	the EDID from the file
	      /tmp/edid1.bin to	the output device VGA-0, and the EDID from the
	      file /tmp/edid2.bin to the output	device DVI-0 and force the DVI
	      port to use the digital encoder.
	      Note that	an output name must always be specified, even if  only
	      one EDID is specified.
	      Caution: Specifying an EDID that doesn't exactly match your dis-
	      play may damage your hardware, as	it allows the driver to	 spec-
	      ify  timings  beyond  the	capabilities of	your display. Use with

       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  col-
	      lected  from  DDC	and BIOS will not be used. If you have a panel
	      with timings different 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.

       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.	  It is	currently only supported on R/RV/RS4xx
	      and older	hardware.

       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 damage	your hardware.	You have been warned. The fre-
	      quency parameter may be specified	as a float value with standard
	      suffixes like "k", "kHz",	"M", "MHz".

       Option "RenderAccel" "boolean"
	      Enables or disables hardware Render acceleration.	  It  is  sup-
	      ported  on  all  Radeon cards when using EXA acceleration	and on
	      Radeon R/RV/RS1xx, R/RV/RS2xx and	RS3xx  when  using  XAA.   The
	      default is to enable Render acceleration.

       Option "AccelMethod" "string"
	      Chooses  between	available  acceleration	 architectures.	 Valid
	      options are XAA and EXA.	XAA is	the  traditional  acceleration
	      architecture  and	support	for it is very stable.	EXA is a newer
	      acceleration architecture	with better performance	for the	Render
	      and Composite extensions.	 The default is	EXA.

       Option "AccelDFS" "boolean"
	      Use  or  don't  use accelerated EXA DownloadFromScreen hook when
	      possible	(only  when  Direct  Rendering	is   enabled,	e.g.).
	      Default:	off  with  AGP	due to issues with GPU->host transfers
	      with some	AGP bridges, on	otherwise.

       Option "FBTexPercent" "integer"
	      Amount of	video RAM to reserve for OpenGL	textures, in  percent.
	      With  EXA,  the  remainder of video RAM is reserved for EXA off-
	      screen management. Specifying 0 results in all  offscreen	 video
	      RAM  being reserved for EXA and only GART	memory being available
	      for OpenGL textures.  This  may  improve	EXA  performance,  but
	      beware  that it may cause	problems with OpenGL drivers from Mesa
	      versions older than 6.4. With XAA, specifying  lower  percentage
	      than  what  gets reserved	without	this option has	no effect, but
	      the driver tries to increase the video RAM reserved for textures
	      to the amount specified roughly.	Default: 50.

       Option "DepthBits" "integer"
	      Precision	 in bits per pixel of the shared depth buffer used for
	      3D acceleration.	Valid values are 16 and	24. When this  is  24,
	      there  will  also	 be a hardware accelerated stencil buffer, but
	      the combined depth/stencil buffer	will take  up  twice  as  much
	      video  RAM  as  when  it's  16.  Default:	The same as the	screen

       Option "DMAForXv" "boolean"
	      Try or don't try to use DMA for Xv image	transfers.  This  will
	      reduce  CPU  usage  when	playing	 big videos like DVDs, but may
	      cause instabilities.  Default: on.

       Option "SubPixelOrder" "string"
	      Force subpixel order to specified	order.	Subpixel order is used
	      for subpixel decimation on flat panels.
	      NONE   --	No subpixel (CRT like displays)
	      RGB    --	in horizontal RGB order	(most flat panels)
	      BGR    --	in horizontal BGR order	(some flat panels)

	      This option is intended to be used in following cases:
	      1. The default subpixel order is incorrect for your panel.
	      2. Enable	subpixel decimation on analog panels.
	      3. Adjust	to one display type in dual-head clone mode setup.
	      4.  Get  better  performance with	Render acceleration on digital
	      panels (use NONE setting).
	      The default is NONE for CRT, RGB for digital panels

       Option "ClockGating" "boolean"
	      Enable dynamic clock gating.  This  can  help  reduce  heat  and
	      increase	battery	 life  by  reducing  power  usage.  Some users
	      report reduced 3D	performance with this enabled.	The default is

       Option "ForceLowPowerMode" "boolean"
	      Enable  a	 static	low power mode.	 This can help reduce heat and
	      increase battery life by reducing	power usage at the expense  of
	      performance. The default is off.

       Option "DynamicPM" "boolean"
	      Enable  dynamic power mode switching.  This can help reduce heat
	      and increase battery life	by reducing power usage	when the  sys-
	      tem is idle (DPMS	active). The default is	off.

       Option "VGAAccess" "boolean"
	      Tell the driver if it can	do legacy VGA IOs to the card. This is
	      necessary	for properly resuming consoles when in VGA text	 mode,
	      but  shouldn't be	if the console is using	radeonfb or some other
	      graphic mode driver. Some	platforms  like	 PowerPC  have	issues
	      with  those,  and	 they  aren't necessary	unless you have	a real
	      text mode	in console. The	default	is off on  PowerPC  and	 SPARC
	      and on on	other architectures.

       Option "ReverseDDC" "boolean"
	      When BIOS	connector information isn't available, use this	option
	      to reverse the mapping of	the two	main DDC ports.	 Use  this  if
	      the  X  server obviously detects the wrong display for each con-
	      nector. This is typically	needed on the Radeon 9600  cards  bun-
	      dled with	Apple G5s. The default is off.

       Option "LVDSProbePLL" "boolean"
	      When  BIOS  panel	 information  isn't  available (like on	Power-
	      Books), it may still be necessary	to use	the  firmware-provided
	      PLL  values for the panel	or flickering will happen. This	option
	      will force probing of the	current	value programmed in  the  chip
	      when  X  is launched in that case.  This is only useful for LVDS
	      panels (laptop internal panels).	The default is on.

       Option "TVDACLoadDetect"	"boolean"
	      Enable load detection on the TV DAC.  The	 TV  DAC  is  used  to
	      drive  both  TV-out and analog monitors. Load detection is often
	      unreliable in the	TV DAC so it  is  disabled  by	default.   The
	      default is off.

       Option "DefaultTMDSPLL" "boolean"
	      Use  the default driver provided TMDS PLL	values rather than the
	      ones provided by the BIOS. This option  has  no  effect  on  Mac
	      cards.  Enable this option if you	are having problems with a DVI
	      monitor using the	internal TMDS controller.  The default is off.

       Option "DefaultTVDACAdj"	"boolean"
	      Use the default driver provided TVDAC Adj	values rather than the
	      ones provided by the BIOS. This option  has  no  effect  on  Mac
	      cards.   Enable  this  option  if	you are	having problems	with a
	      washed out display on the	secondary DAC.	The default is off.

       Option "DRI" "boolean"
	      Enable DRI support.  This	option allows you to enable to disable
	      the  DRI.	 The default is	off for	RN50/ES1000 and	on for others.

       Option "DefaultConnectorTable" "boolean"
	      Enable this option to skip the BIOS connector table parsing  and
	      use the driver defaults for each chip.  The default is off

       Option "MacModel" "string"
	      Used  to specify Mac models for connector	tables and quirks.  If
	      you have a PowerBook or Mini with	DVI that does not  work	 prop-
	      erly,  try  the alternate	options	as Apple does not seem to pro-
	      vide a good way of knowing whether they use internal or external
	      TMDS for DVI.  Only valid	on PowerPC.  On	Linux, the driver will
	      attempt to detect	the MacModel automatically.
	      ibook		   -- ibooks
	      powerbook-external   -- Powerbooks with external DVI
	      powerbook-internal   -- Powerbooks with integrated DVI
	      powerbook-vga	   -- Powerbooks with VGA rather than DVI
	      mini-external	   -- Mac Mini with external DVI
	      mini-internal	   -- Mac Mini with integrated DVI
	      imac-g5-isight	   -- iMac G5 iSight
	      emac		   -- eMac G4
	      sam440ep		   -- SAM440ep embedded	board
	      The default value	is undefined.

       Option "TVStandard" "string"
	      Used to specify the default TV standard if you want to use some-
	      thing other than the BIOS	default. Valid options are:
	      The default value	is undefined.

       Option "ForceTVOut" "boolean"
	      Enable  this  option  to	force  TV-out to always	be detected as
	      attached.	 The default is	off

       Option "IgnoreLidStatus"	"boolean"
	      Enable this option to ignore lid status on  laptops  and	always
	      detect LVDS as attached.	The default is on.

       Option "Int10" "boolean"
	      This  option  allows  you	 to disable INT10 initialization.  Set
	      this to False if you are experiencing a hang when	initializing a
	      secondary	card.  The default is on.

       Option "ATOMTvOut" "boolean"
	      This  option  enables  experimental  TV-out support for R/RV5xx,
	      R/RV6xx, and R/RV7xx AtomBIOS chips. TV-out is experimental  and
	      may  not	function  on  these  chips  as well as hoped for.  The
	      default is off.

       Option "R4xxATOM" "boolean"
	      This option enables modesetting on R/RV4xx chips using AtomBIOS.
	      The default is off.

       The driver supports the following X11 Xv	attributes for Textured	Video.
       You can use the "xvattr"	tool to	query/set those	attributes at runtime.

	      XV_VSYNC	is  used  to control whether textured adapter synchro-
	      nizes the	screen update to the monitor vertical refresh to elim-
	      inate  tearing.	It  has	 two values: 'off'(0) and 'on'(1). The
	      default is 'on'(1).

	      XV_CRTC is used to control which display controller  (crtc)  the
	      textured	adapter	 synchronizes  the  screen  update  with  when
	      XV_VSYNC is enabled.  The	default, 'auto'(-1), will sync to  the
	      display  controller  that	 more of the video is on; when this is
	      ambiguous, the display controller	associated with	the RandR pri-
	      mary  output  is preferred.  This	attribute is useful for	things
	      like clone mode where the	user can  best	decide	which  display
	      should be	synced.	 The default is	'auto'(-1).

	      XV_BICUBIC  is  used  to control whether textured	adapter	should
	      apply a bicubic filter to	smooth the output. It has  three  val-
	      ues:  'off'(0),  'on'(1)	and 'auto'(2). 'off' means never apply
	      the filter, 'on' means always apply the filter and 'auto'	 means
	      apply  the  filter  only if the X	and Y sizes are	scaled to more
	      than double to avoid blurred output.  Bicubic filtering  is  not
	      currently	 compatible  with  other  Xv attributes	like hue, con-
	      trast, and  brightness,  and  must  be  disabled	to  use	 those
	      attributes.  The default is 'off'(0).
