DESCRIPTION
       cyrix  is  an Xorg driver for the Cyrix MediaGX (now Natsemi Geode) se-
       ries 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 ac-
       celeration.

       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 xorg.conf(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 en-
	      abled.

       Option "SWCursor" "boolean"
	      Disable or enable	software cursor. Default  software  cursor  is
	      enabled and a hardware cursor is used.

       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 unaccelerated.

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.

       Xorg  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.
