5.3 The 3D DRI Driver

The 3D capabilities of a graphics card are accessed through the 3D DRI driver. This driver essentially converts OpenGL command sequences into hardware commands. It then uses the kernel module to transmit the commands to the hardware. The 3D driver and kernel module basically implement the entire OpenGL rendering pipeline. The 3D driver implements as much of it as possible in user space while the kernel module does whatever is needed in kernel space.

3D DRI drivers usually reside in the /usr/X11R6/lib/modules/dri/ directory with names of the form device_dri.so.

These drivers are loaded by the libGL.so library which implements the OpenGL API.

Most DRI 3D drivers today are based on Mesa. However, there is no DRI requirement to use Mesa. Driver developers may implement their 3D DRI drivers using any OpenGL-compatible software framework.

5.4 The libGL Library

OpenGL-based programs must link with the libGL library. libGL implements the GLX interface as well as the main OpenGL API entrypoints. When using indirect rendering, libGL creates GLX protocol messages and sends them to the X server via a socket. When using direct rendering, libGL loads the appropriate 3D DRI driver then dispatches OpenGL library calls directly to that driver.

libGL also has the ability to support heterogeneous, multi-head configurations. That means one could have two or more graphics cards (of different types) in one system and libGL would allow an application program to use all of them simultaneously.

Normally libGL loads 3D DRI drivers from the /usr/X11R6/lib/modules/dri directory but the search patch can be overriden by setting the LIBGL_DRIVERS_PATH environment variable.
