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.

     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.
