37  * \mainpage
38  *
39  * The Direct Rendering Manager (DRM) is a device-independent kernel-level
40  * device driver that provides support for the XFree86 Direct Rendering
41  * Infrastructure (DRI).
42  *
43  * The DRM supports the Direct Rendering Infrastructure (DRI) in four major
44  * ways:
45  *     -# The DRM provides synchronized access to the graphics hardware via
46  *        the use of an optimized two-tiered lock.
47  *     -# The DRM enforces the DRI security policy for access to the graphics
48  *        hardware by only allowing authenticated X11 clients access to
49  *        restricted regions of memory.
50  *     -# The DRM provides a generic DMA engine, complete with multiple
51  *        queues and the ability to detect the need for an OpenGL context
52  *        switch.
53  *     -# The DRM is extensible via the use of small device-specific modules
54  *        that rely extensively on the API exported by the DRM module.
