NAME
tdfx --- Voodoo Graphics and VoodooII Memory Access GLIDE device driver
SYNOPSIS
device tdfx
device tdfx_linux
DESCRIPTION
This driver creates an entry in /dev that allows programs (mostly
GLIDE-based software) to access the device memory of the Voodoo Graphics
and VoodooII 3D accelerators created by 3Dfx, Inc. This provides an
interface for applications based on the GLIDE API or that simply use the
API provided by the linux /dev/3dfx device to use the video device.
Supports all cards based on the following chipsets:
3Dfx Voodoo Graphics
3Dfx Voodoo II
Specifically, the following cards should work:
Diamond Multimedia Monster 3D
Diamond Multimedia Monster 3D II
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.
By including tdfx_linux, you can enable the linux ioctl code for this
driver, where the only supported applications currently reside.

HISTORY
The tdfx driver appeared in FreeBSD 5.0, and was originally developed for
Linux kernel 2.0.x, later written for 2.2.x and 2.4.x.
AUTHORS
The driver was developed by Coleman Kane cokane@micro.ti.com after the
linux version of this driver by Darryll Straus, John Taylor, Jens Axboe,
Carlo Wood carlo@alinoe.com and Joseph Kain joseph@3dfx.com to be
directly compatible with it and support the many GLIDE based games
available for Linux and UNIX.
