-.Sh NAME
-.Nm tdfx
-.Nd Voodoo Graphics and VoodooII Memory Access GLIDE device driver
-.Sh SYNOPSIS
-.Cd device tdfx
-.Sh DESCRIPTION
-This driver creates an entry in
-.Pa /dev
-that allows programs (mostly
-.Em GLIDE-based software )
-to access the device memory of the Voodoo Graphics and
-VoodooII 3D accelerators created by
-.Em 3Dfx, Inc .
-This provides an interface
-for applications based on the
-.Em GLIDE API
-or that simply use the API
-provided by the linux
-.Pa /dev/3dfx
-device to use the video device.
-.Pp
-Supports all cards based on the following chipsets:
-.Pp
-.Bl -item -offset indent -compact
-.It
-.Em 3Dfx Voodoo Graphics
-.It
-.Em 3Dfx Voodoo II
-.El
-.Pp
-Specifically, the following cards should work:
-.Pp
-.Bl -item -offset indent -compact
-.It
-.Em Diamond Multimedia Monster 3D
-.It
-.Em Diamond Multimedia Monster 3D II
-.El
-.Pp
-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.
-.Pp
-By loading the
-.Nm tdfx_linux.ko
-and
-.Nm linux.ko
-modules, you can enable the linux ioctl code for this driver, where the only supported
-applications currently reside.

-.Xr linux 4 ,
-.Xr kldload 8
-.Sh HISTORY
-The
-.Nm
-driver appeared in
-.Fx 5.0 ,
-and was originally developed for Linux kernel 2.0.x, later written for
-2.2.x and 2.4.x.
-.Sh AUTHORS
-.An -nosplit
-The driver was developed by
-.An Coleman Kane Aq Mt cokane@micro.ti.com
-after the linux version of this driver by
-.An Darryll Straus ,
-.An John Taylor ,
-.An Jens Axboe ,
-.An Carlo Wood Aq Mt carlo@alinoe.com
-and
-.An Joseph Kain Aq Mt joseph@3dfx.com
-to be directly compatible with it and support the many GLIDE based games
-available for Linux and
-.Ux .
