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 sup-
ported in depth 8, other depths only support TrueColor. The driver
supports hardware accelerated 3D via the Direct Rendering Infrastruc-
ture (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(5x) 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 mem-
ory 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
Option "NoAccel" "boolean"
Disable or enable acceleration. Default: acceleration is
Option "SWCursor" "boolean"
Disable or enable software cursor. Default: software cursor is
disable and a hardware cursor is used.
Option "ColorKey" "integer"
This sets the default pixel value for the YUV video overlay key.
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 per-
formance at the expense of 3D performance. Default: 256 to 768
depending on the resolution and depth.
