     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.
