# tdfx(4freebsd)

Voodoo Graphics and VoodooII Memory Access GLIDE device driver

## 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.
