This stuff is ancient, we have docs now in the kernel,
lets just drop it.

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:



    1. The DRM provides synchronized access to the graphics hardware via

       the use of an optimized two-tiered lock.



    2. 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.



    3. The DRM provides a generic DMA engine, complete with multiple

       queues and the ability to detect the need for an OpenGL context

       switch.



    4. The DRM is extensible via the use of small device-specific modules

       that rely extensively on the API exported by the DRM module.





Documentation on the DRI is available from:

    http://dri.freedesktop.org/wiki/Documentation

    http://sourceforge.net/project/showfiles.php?group_id=387

    http://dri.sourceforge.net/doc/
