DESCRIPTION
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.
SUPPORTED HARDWARE
i810 supports the i810, i810-DC100, i810e, i815, 830M,
845G, 852GM, 855GM, and 865G chipsets.
CONFIGURATION DETAILS
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 Vide
oRam 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: accelera
tion is enabled.
Option "SWCursor" "boolean"
Disable or enable software cursor. Default: soft
ware cursor is disable and a hardware cursor is
used.
Option "ColorKey" "integer"
This sets the default pixel value for the YUV video
4.3.0 Version 1

overlay key. Default: undefined.
Option "CacheLines" "integer"
This allows the user to change the amount of graph
ics 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.
