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. +.SH SUPPORTED HARDWARE +The +.B chips +driver supports video processors on most of the bus types currently available. +The chipsets supported fall into one of three architectural classes. A +.B basic +architecture, the +.B WinGine +architecture and the newer +.B HiQV +architecture. +.PP +.B Basic Architecture +.PP +The supported chipsets are +.B ct65520, ct65525, ct65530, ct65535, ct65540, ct65545, ct65546 +and +.B ct65548 +.PP +Color depths 1, 4 and 8 are supported on all chipsets, while depths 15, 16 +and 24 are supported only on the +.B 65540, 65545, 65546 +and +.B 65548 +chipsets. The driver is accelerated when used with the +.B 65545, 65546 +or +.B 65548 +chipsets, however the DirectColor visual is not available. +.PP +.B Wingine Architecture +.PP +The supported chipsets are +.B ct64200 +and +.B ct64300 +.PP +Color depths 1, 4 and 8 are supported on both chipsets, while depths 15, 16 +and 24 are supported only on the +.B 64300 +chipsets. The driver is accelerated when used with the +.B 64300 +chipsets, however the DirectColor visual is not available. +.PP +.B HiQV Architecture +.PP +The supported chipsets are +.B ct65550, ct65554, ct65555, ct68554, ct69000 +and +.B ct69030 +.PP +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. +.SH CONFIGURATION DETAILS +Please refer to XF86Config(__filemansuffix__) for general configuration +details. This section only covers configuration details specific to this +driver. +.PP +The driver auto-detects the chipset type, but the following +.B ChipSet +names may optionally be specified in the config file +.B \*qDevice\*q +section, and will override the auto-detection: +.PP +.RS 4 +"ct65520", "ct65525", "ct65530", "ct65535", "ct65540", "ct65545", "ct65546", +"ct65548", "ct65550", "ct65554", "ct65555", "ct68554", "ct69000", "ct69030", +"ct64200", "ct64300". +.RE +.PP +The driver will auto-detect the amount of video memory present for all +chipsets. But maybe overridden with the +.B VideoRam +entry in the config file +.B \*qDevice\*q +section. +.PP +The following driver +.B Options +are supported, on one or more of the supported chipsets: +.TP +.BI "Option \*qNoAccel\*q \*q" boolean \*q +Disable or enable acceleration. Default: acceleration is enabled. +.TP +.BI "Option \*qNoLinear\*q \*q" boolean \*q +Disables linear addressing in cases where it is enabled by default. +Default: off +.TP +.BI "Option \*qLinear\*q \*q" boolean \*q +Enables linear addressing in cases where it is disabled by default. +Default: off +.TP +.BI "Option \*qHWCursor\*q \*q" boolean \*q +Enable or disable the HW cursor.

If not specified, half the memory is used. +Default: off. +.TP +.BI "Option \*qDualRefresh\*q \*q" integer \*q +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. +.SH "SEE ALSO" +XFree86(1), XF86Config(__filemansuffix__), xf86config(1), Xserver(1), X(__miscmansuffix__) +.PP +You are also recommended to read the README.chips file that comes with all +XFree86 distributions, which discusses the +.B chips +driver in more detail. +.SH AUTHORS +Authors include: Jon Block, Mike Hollick, Regis Cridlig, Nozomi Ytow, +Egbert Eich, David Bateman and Xavier Ducoin + |
