-/**
- * \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.
- *
