DESCRIPTION
       cyrix  is  an  XFree86 driver for the Cyrix MediaGX (now	Natsemi	Geode)
       series of processors when using the built in video.

SUPPORTED HARDWARE
       The cyrix driver	supports the MediaGX, MediaGXi	and  MediaGXm  proces-
       sors,  as  well	as the Natsemi 'Geode' branded processors. It supports
       the CS5510, CS5520, CS5530 and CS5530A companion	chips. The driver sup-
       ports  4,  8,  15  and  16 bit deep displays with video compression and
       acceleration.

       The MediaGX run length compresses its shared framebuffer, for the  best
       performance  on	a  MediaGX machine pick	backgrounds that compress well
       horizonally.

CONFIGURATION DETAILS
       Please refer to XF86Config(5) for general configuration details.	  This
       section only covers configuration details specific to this driver.

       The following driver options are	supported:

       Option "NoAccel"	"boolean"
	      Disable	or   enable  acceleration.  Default:  acceleration  is
	      enabled.

       Option "SWCursor" "boolean"
	      Disable or enable	software cursor. Default: software  cursor  is
	      enabled.

       Option "HWCursor" "boolean"
	      Disable  or  enable hardware cursor. Default: hardware cursor is
	      disabled.

       Option "ShadowFB" "boolean"
	      Disable or enable	shadow frame buffer. The shadow	buffer is nor-
	      mally  only used when rotating the screen. The default is	false.

       Option "Rotate" "CW"

       Option "Rotate" "CCW"
	      Rotate the display clockwise  or	counterclockwise  for  use  on
	      Cyrix based tablet PC systems. This mode is currently unacceler-
	      ated.  Default: no rotation.

BUGS
       This driver has not been	tested on the original 5510 hardware for  some
       considerable time.

       8bit mode does not currently work on the	CS5510 with external RAMDAC.

       The 5530A video overlay facility	is not currently supported.

       XFree86	uses  the  MediaGX  'SoftVGA'  interface. On a small number of
       boards this is buggy and	may  result  in	 strange  illegal  instruction
       traps.

       Hardware	cursors	are not	currently supported.
