Direct Rendering Open Source Project

The Direct Rendering Infrastructure, also known as the DRI, is a framework for allowing direct access to graphics hardware under the X Window System in a safe and efficient manner. It includes changes to the X server, to several client libraries, and to the kernel (DRM, Direct Rendering Manager). The most important use for the DRI is to create fast OpenGL implementations. The DRI is an integral part of X.org 7.x, and integrates with Mesa, an open source implementation of the OpenGL API. Several 3D accelerated drivers have been written to the DRI specification, including drivers for chipsets produced by ATI, Matrox, 3DFX, and Intel. The DRI was initially developed by Precision Insight, Inc. (PI) in cooperation with, and partially funded by Red Hat Inc., and SGI. Since PI's merger with VA Linux, and VA Linux' subsequent exit from Linux, the DRI is being maintained by Tungsten Graphics Inc., a new company formed by some of the initial DRI developers from PI. Tungsten Graphics is the current focal point for DRI development, and many open source developers continue to contribute to the project through the DRI project.
