i810 - Intel 8xx integrated graphics chipsets
i810 is an XFree86 driver for Intel integrated graphics chipsets.
The driver supports depths 8, 15, 16 and 24. All visual types are supported
in depth 8, other depths only support TrueColor. The driver supports hardware
accelerated 3D via the Direct Rendering Infrastructure (DRI), but only
in depth 16 for the i810/i815 and depths 16 and 24 for later chipsets.
i810 supports the i810, i810-DC100, i810e, i815, 830M, 845G, 852GM,
855GM, and 865G chipsets.
Please refer to XF86Config(5)
for general configuration details. This section only covers configuration
details specific to this driver.
The Intel 8xx family of integrated graphics
chipsets has a unified memory architecture and uses system memory for video
ram. By default 8 Megabytes of system memory are used for graphics. For
the 830M and later, the default is 8 Megabytes when DRI is not enabled
and 32 Megabytes with DRI is enabled. This amount may be changed with the
VideoRam entry in the config file Device section. It may be set to any
reasonable value up to 64MB for older chipsets or 128MB for newer chipets.
Note that increasing this value will reduce the amount of system memory
available for other applications.
The following driver Options are supported
Keith Whitwell, and also Jonathan Bian, Matthew J Sottek, Jeff Hartmann,
Mark Vojkovich, Alan Hourihane, H. J. Lu. 830M and 845G support reworked
for XFree86 4.3 by David Dawes and Keith Whitwell. 852GM, 855GM, and 865G
support added by David Dawes and Keith Whitwell.
- Option "NoAccel" "boolean"
- Disable or enable acceleration. Default: acceleration
- Option "SWCursor" "boolean"
- Disable or enable software cursor.
Default: software cursor is disable and a hardware cursor is used.
- This sets the default pixel value for the YUV video
overlay key. Default: undefined.
- Option "CacheLines" "integer"
- This allows
the user to change the amount of graphics memory used for 2D acceleration
and video. Decreasing this amount leaves more for 3D textures. Increasing
it can improve 2D performance at the expense of 3D performance. Default:
256 to 768 depending on the resolution and depth.
