40  * \mainpage
41  *
42  * The Direct Rendering Manager (DRM) is a device-independent kernel-level
43  * device driver that provides support for the XFree86 Direct Rendering
44  * Infrastructure (DRI).
45  *
46  * The DRM supports the Direct Rendering Infrastructure (DRI) in four major
47  * ways:
48  *     -# The DRM provides synchronized access to the graphics hardware via
49  *        the use of an optimized two-tiered lock.
50  *     -# The DRM enforces the DRI security policy for access to the graphics
51  *        hardware by only allowing authenticated X11 clients access to
52  *        restricted regions of memory.
53  *     -# The DRM provides a generic DMA engine, complete with multiple
54  *        queues and the ability to detect the need for an OpenGL context
55  *        switch.
56  *     -# The DRM is extensible via the use of small device-specific modules
57  *        that rely extensively on the API exported by the DRM module.
