/**
 * \mainpage
 *
 * The Direct Rendering Manager (DRM) is a device-independent kernel-level
 * device driver that provides support for the XFree86 Direct Rendering
 * Infrastructure (DRI).
 *
 * The DRM supports the Direct Rendering Infrastructure (DRI) in four major
 * ways:
 *     -# The DRM provides synchronized access to the graphics hardware via
 *        the use of an optimized two-tiered lock.
 *     -# The DRM enforces the DRI security policy for access to the graphics
 *        hardware by only allowing authenticated X11 clients access to
 *        restricted regions of memory.
 *     -# The DRM provides a generic DMA engine, complete with multiple
 *        queues and the ability to detect the need for an OpenGL context
 *        switch.
 *     -# The DRM is extensible via the use of small device-specific modules
 *        that rely extensively on the API exported by the DRM module.
 *
