       siliconmotion - Silicon Motion video driver

       Section "Device"
	 Identifier "devname"
	 Driver "siliconmotion"
	 [ Option "optionname" ["optionvalue"]]

       siliconmotion  is  an  XFree86 driver for Silicon Motion based video cards.  The driver is
       fully accelerated, and provides support for the following framebuffer depths: 8,  16,  and
       24.   All  visual types are supported for depth 8, and TrueColor visuals are supported for
       the other depths.

       The siliconmotion driver supports PCI and AGP video cards based on the  following  Silicon
       Motion chips:

       Lynx	   SM910

       LynxE	   SM810

       Lynx3D	   SM820

       LynxEM	   SM710

       LynxEM+	   SM712

       Lynx3DM	   SM720

       Please  refer to XF86Config(5x) for general configuration details.  This section only cov-
       ers configuration details specific to this driver.  All options names are case  and  white
       space insensitive when parsed by the server, for example,  "lynxe" and "LynxE" are equiva-

       The driver auto-detects the chipset type, but the following ChipSet names  may  optionally
       be specified in the config file "Device" section, and will override the auto-detection:

	   "lynx", "lynxe", "lynx3d", "lynxem", "lynxem+", "lynx3dm".

       The following Cursor Options are supported:

       Option "HWCursor" "boolean"
	      Enable or disable the HW cursor.	Default: on.

       Option "SWCursor" "boolean"
	      Inverse of "HWCursor".  Default: off.

       The following display Options are supported:

       Option "ShadowFB" "boolean"
	      Use shadow framebuffer.  Default: off.

       Option "Rotate" "CW"

       Option "Rotate" "CCW"
	      Rotate  the  screen  CW  -  clockwise  or  CCW - counter clockwise.  Uses ShadowFB.
	      Default: no rotation.

       Option "VideoKey" "integer"
	      Set the video color key.	Default: a little off full blue.

       Option "ByteSwap" "boolean"
	      Turn on byte swapping for capturing using SMI demo board.  Default: off.

       Option "Interlaced" "boolean"
	      Turn on interlaced video capturing.  Default: off.

       Option "UseBIOS" "boolean"
	      Use the BIOS to set the modes. This is used for custom panel timings.  Default: on.

       Option "ZoomOnLCD" "boolean"
	      Allow changing resolution on LCD (Ctrl-Alt-Plus and Ctrl-Alt-Minus).  Default: off.

       The following video memory Options are supported:

       Option "set_mclk" "integer"
	      sets the memory clock, where integer is in kHz, and integer  <=  100000.	 Default:
	      probe the memory clock value, and use it at server start.

       The following acceleration and graphics engine Options are supported:

       Option "NoAccel"
	      Disable  acceleration.  Very useful for determining if the driver has problems with
	      drawing and acceleration routines.  This is the first option to try if your  server
	      runs but you see graphic corruption on the screen.  Using it decreases performance,
	      as it uses software emulation for drawing operations the video driver can  acceler-
	      ate with hardware.  Default: acceleration is enabled.

       Option "fifo_aggressive"

       Option "fifo_moderate"

       Option "fifo_conservative"
	      alter  the settings for the threshold at which the pixel FIFO takes over the inter-
	      nal memory bus to refill itself. The smaller this threshold, the better the  accel-
	      eration  performance of the card. You may try the fastest setting (fifo_aggressive)
	      and move down if you encounter pixel corruption.	The optimal setting will probably
	      depend  on  dot-clock and on color depth. Note that specifying any of these options
	      will also alter other memory settings which may  increase  performance,  so  trying
	      fifo_conservative  will  in  most  cases	be  a  slight benefit (this uses the chip
	      defaults).  If pixel corruption or transient streaking is observed  during  drawing
	      operations then removing any fifo options is recommended.  Default: none.

       The following PCI bus Options are supported:

       Option "pci_burst" "boolean"
	      will  enable PCI burst mode. This should work on all but a few broken PCI chipsets,
	      and will increase performance.  Default: off.

       Option "pci_retry" "boolean"
	      will allow the driver to	rely  on  PCI  Retry  to  program  the	ViRGE  registers.
	      pci_burst  must be enabled for this to work.  This will increase performance, espe-
	      cially for small fills/blits, because the driver does not have to  poll  the  ViRGE
	      before  sending it commands to make sure it is ready. It should work on most recent
	      PCI chipsets.  Default: off.

       The following additional Options are supported:

       Option "ShowCache" "boolean"
	      Enable or disable viewing offscreen cache  memory.   A  development  debug  option.
	      Default: off.

       For  assistance	with  this  driver,  or XFree86 in general, check the XFree86 web site at
       http://www.xfree86.org.	   A	FAQ    is    available	  on	the    web    site     at
       http://www.xfree86.org/FAQ/.   If  you  find a problem with XFree86 or have a question not
       answered in the FAQ please use our bug report form available on the web site or send  mail
       to  XFree86@XFree86.org.   When	reporting problems with the driver send as much detail as
       possible, including chipset type, a server output log, and operating system specifics.
