DESCRIPTION

       chips  is  an  Xorg driver for Chips and Technologies video processors.
       The majority of the Chips and Technologies chipsets  are  supported  by
       this  driver.  In  general  the  limitation on the capabilities of this
       driver are determined  by  the  chipset  on  which  it  is  run.  Where
       possible,  this  driver  provides  full  acceleration  and supports the
       following depths: 1, 4, 8, 15, 16, 24 and on  the  latest  chipsets  an
       8+16  overlay mode. All visual types are supported for depth 1, 4 and 8
       and  both  TrueColor  and  DirectColor  visuals  are  supported   where
       possible. Multi-head configurations are supported on PCI or AGP buses.

SUPPORTED HARDWARE

       The  chips  driver  supports  video processors on most of the bus types
       currently available.  The chipsets supported fall  into  one  of  three
       architectural  classes.  A basic architecture, the WinGine architecture
       and the newer HiQV architecture.

       Basic Architecture

       The supported chipsets are ct65520, ct65525, ct65530, ct65535, ct65540,
       ct65545, ct65546 and ct65548

       Color depths 1, 4 and 8 are supported on all chipsets, while depths 15,
       16 and 24 are supported only on  the  65540,  65545,  65546  and  65548
       chipsets.  The driver is accelerated when used with the 65545, 65546 or
       65548 chipsets, however the DirectColor visual is not available.

       Wingine Architecture

       The supported chipsets are ct64200 and ct64300

       Color depths 1, 4 and 8 are supported on both  chipsets,  while  depths
       15,  16  and 24 are supported only on the 64300 chipsets. The driver is
       accelerated when used with the 64300 chipsets, however the  DirectColor
       visual is not available.

       HiQV Architecture

       The  supported chipsets are ct65550, ct65554, ct65555, ct68554, ct69000
       and ct69030

       Color depths 1, 4, 8,  15,  16,  24  and  8+16  are  supported  on  all
       chipsets.   The  DirectColor  visual  is  supported on all color depths
       except the 8+16 overlay mode. Full acceleration  is  supplied  for  all
       chipsets.

CONFIGURATION DETAILS

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

       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:

           "ct65520", "ct65525", "ct65530", "ct65535",  "ct65540",  "ct65545",
           "ct65546",  "ct65548",  "ct65550", "ct65554", "ct65555", "ct68554",
           "ct69000", "ct69030", "ct64200", "ct64300".

       The driver will auto-detect the amount of video memory present for  all
       chipsets.   But  maybe overridden with the VideoRam entry in the config
       file "Device" section.

       The following driver Options are supported,  on  one  or  more  of  the
       supported chipsets:

       Option "NoAccel" "boolean"

              Force the use of memory mapped IO where it can be used. Default:
              off

       Option "SuspendHack" "boolean"
              Force  driver to leave centering and stretching registers alone.
              This can fix some laptop suspend/resume problems. Default: off

       Option "Overlay"
              Enable 8+24  overlay  mode.   Only  appropriate  for  depth  24.

       Option "ColorKey" "integer"
              Set  the  colormap  index  used for the transparency key for the
              depth 8 plane when operating in 8+16 overlay  mode.   The  value
              must be in the range 2-255.  Default: 255.

       Option "VideoKey" "integer"
              This sets the default pixel value for the YUV video overlay key.
              Default: undefined.

       Option "ShadowFB" "boolean"
              Enable or disable use of the shadow framebuffer layer.  Default:
              off.

       Option "SyncOnGreen" "boolean"
              Enable  or  disable  combining  the  sync signals with the green
              signal.  Default: off.

       Option "ShowCache" "boolean"
              Enable or disable viewing offscreen memory. Used  for  debugging
              only Default: off.

       Option "18bitBus" "boolean"
              Force the driver to assume that the flat panel has an 18bit data
              bus.  Default: off.

       Option "Crt2Memory" "integer"
              In a dual-head mode (69030 only) this option selects the  amount
              of  memory  to  set aside for the second head. If not specified,
              half the memory is used.  Default: off.

       Option "DualRefresh" "integer"
              The 69030 supports independent refresh rates on its two  display
              channels.   This  mode  of  operations  uses  additional  memory
              bandwidth and thus limits the maximum colour depth  and  refresh
              rate that can be achieved, and so is off by default.  Using this
              option forces the use of an independent refresh rate on the  two
              screens.  Default: off.

       Option "FpMode" "boolean"
              The  driver probes the chip to find out if a flat panel (LCD) is
              connected and active. If this is true  it  limits  the  possible
              screen size to the maximum resolution of the panel. The chips is
              initialized by the BIOS which may set the chip  to  'dual'  mode
              even  if  no  panel  is  connected.  In  this case the available
              resolution on the CRT is limited to the panel size the BIOS  has
              set.  To  tell  the driver that no panel is connected despite of
              what the BIOS is saying set this option to off. Don't set it  to
              off if a panel is connected.  Default: value probed by BIOS.
