-************************************************************
-* For the very latest on DRI development, please see: *
-* http://dri.sourceforge.net/ *
-************************************************************
-
-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://precisioninsight.com/piinsights.html

-For specific information about kernel-level support, see:
