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.
