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

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.
