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.
