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