       o RandR 1.2 and RandR 1.3 support;
       o Full EXA 2D acceleration;
       o Textured XVideo acceleration including	anti-tearing support  (Bicubic
	 filtering   only  available  on  R/RV3xx,  R/RV/RS4xx,	 R/RV5xx,  and
	 RS6xx/RS740);
       o 3D acceleration;

CONFIGURATION DETAILS
       Please refer to xorg.conf(5) for	general	configuration  details.	  This
       section only covers configuration details specific to this driver.

       The following driver Options are	supported:

       Option "SWcursor" "boolean"
	      Selects software cursor.	The default is off.

       Option "Accel" "boolean"
	      Enables or disables all hardware acceleration.
	      The default is on.

       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 "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,	CAYMAN,	ARUBA,
	      Southern Islands,	 and  Sea  Islands  and	 off  for  R/RV/RS1XX,
	      R/RV/RS2XX, RS3XX, and RS690/RS780/RS880 when fast fb feature is
	      enabled.

       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	and requires Mesa 9.0 or newer
	      for R6xx-ARUBA, Mesa 9.2 or newer	for Southern Islands, and Mesa
	      10.1 or newer for	Sea Islands.
	      The  default  value  is  on  for R/RV6XX,	R/RV7XX, RS780,	RS880,
	      EVERGREEN, CAYMAN, ARUBA,	Southern Islands, and Sea Islands.

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

       Option "AccelMethod" "string"
	      Chooses  between	available  acceleration	 architectures.	 Valid
	      values are EXA (for pre-TAHITI GPUs) and	glamor	(for  R300  or
	      higher). The default is glamor as	of TAHITI, otherwise EXA.

       The following driver Options are	supported for EXA :

       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.

       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 or when fast	fb feature  is
	      enabled for RS690/RS780/RS880.

       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.

TEXTURED VIDEO ATTRIBUTES
       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
	      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
	      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
	      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).
