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.
