+# The purpose of this Makefile is to handle setting up everything

+# everything required for in-kernel source builds.  It is included into
+# this file, so none of that should be duplicated here.

+************************************************************

+*     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:
+
+    The Direct Rendering Manager, Kernel Support for the Direct Rendering
+    Infrastructure
