DESCRIPTION

      cyrix  is  an  Xorg 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 processors, as well as the Natsemi  'Geode'  branded
      processors.  It supports the CS5510, CS5520, CS5530 and CS5530A companion chips. The driver supports 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 xorg.conf(5x) 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 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 normally 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.
