SYNOPSIS

... EndSectionDESCRIPTION
chips is an Xorg driver for Chips and Technologies video
processors. The majority of the Chips and Technologieschipsets are supported by this driver. In general the limi-
tation on the capabilities of this driver are determined bythe chipset on which it is run. Where possible, this driver
provides full acceleration and supports the followingdepths: 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 aresupported where possible. Multi-head configurations are sup-
ported on PCI or AGP buses. SUPPORTED HARDWAREThe 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 architec-
ture, the WinGine architecture and the newer HiQV architec-
ture. Basic ArchitectureThe supported chipsets are ct65520, ct65525, ct65530,
ct65535, ct65540, ct65545, and ct65548Color 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 ArchitectureThe 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 64300chipsets. The driver is accelerated when used with the 64300
chipsets, however the DirectColor visual is not available.

Device and Network Interfaces CHIPS(7)The supported chipsets are ct65550, ct65554, ct65555,
ct68554, ct69000 and ct69030 Color depths 1, 4, 8, 15, 16, 24 and 8+16 are supported onall chipsets. The DirectColor visual is supported on all
color depths except the 8+16 overlay mode. Full accelerationis supplied for all chipsets.
CONFIGURATION DETAILS Please refer to xorg.conf(4) 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 moreof 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 theX Version 11 Last change: xf86-video-chips 1.2.3 2
Device and Network Interfaces CHIPS(7) modeline. Default: off Option "FixPanelSize" "boolean"Reprogram flat panel size with values from the mode-
line. 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 regis-
ters 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 keyX Version 11 Last change: xf86-video-chips 1.2.3 3
Device and Network Interfaces CHIPS(7) for the depth 8 plane when operating in 8+16 overlaymode. 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 twodisplay channels. This mode of operations uses addi-
tional 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 lim-
its the possible screen size to the maximum resolutionof 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.X Version 11 Last change: xf86-video-chips 1.2.3 4
