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"
              Disable or enable acceleration.  Default: acceleration is enabled.

       Option "NoLinear" "boolean"
              Disables linear addressing in cases where it is enabled by default.  Default: off

       Option "Linear" "boolean"
              Enables linear addressing in cases where it is disabled by default.  Default: off

       Option "HWCursor" "boolean"
              Enable or disable the HW cursor.  Default: on.

       Option "SWCursor" "boolean"
              Enable or disable the SW cursor.  Default: off.

       Option "STN" "boolean"
              Force detection of STN screen type. Default: off.

       Option "UseModeline" "boolean"
              Reprogram flat panel timings with values from the modeline. Default: off

       Option "FixPanelSize" "boolean"
              Reprogram flat panel size with values from the modeline. Default: off

       Option "NoStretch" "boolean"
              This option disables the stretching on a mode on a flat panel to fill  the  screen.
              Default: off

       Option "LcdCenter" "boolean"
              Center the mode displayed on the flat panel on the screen. Default: off

       Option "HWclocks" "boolean"
              Force  the  use  of  fixed  hardware  clocks  on  chips that support both fixed and
              programmable clocks. Default: off

       Option "UseVclk1" "boolean"
              Use the Vclk1 programmable clock on HiQV chipsets instead of Vclk2. Default: off

       Option "FPClock8" "float"

       Option "FPClock16" "float"

       Option "FPClock24" "float"

       Option "FPClock32" "float"
              Force the use of a particular video clock speed for use with the flat  panel  at  a
              specified depth

       Option "MMIO" "boolean"
              Force the use of memory mapped IO for acceleration registers. Default: off

       Option "FullMMIO" "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.  Default: off.

       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.
