.Sh DESCRIPTION
|
|
This driver creates an entry in
|
|
.Pa /dev
|
|
that allows programs (mostly
|
|
.Em GLIDE-based software )
|
|
to access the device memory of the Voodoo Graphics and
|
|
VoodooII 3D accelerators created by
|
|
.Em 3Dfx, Inc .
|
|
This provides an interface
|
|
for applications based on the
|
|
.Em GLIDE API
|
|
or that simply use the API
|
|
provided by the linux
|
|
.Pa /dev/3dfx
|
|
device to use the video device.

Note that this driver does not currently have support for the Voodoo
|
|
Banshee, Voodoo3, Voodoo5, or Voodoo6 based cards.
|
|
It also does not currently support the Voodoo Rush.
|
|
It also does not yet handle the SLI feature of the Voodoo II boards.
|
|
You can only use each of them separately.
|
|
.Pp
|
|
By including
|
|
.Nm tdfx_linux ,
|
|
you can enable the linux ioctl code for this driver, where the only supported
|
|
applications currently reside.
