+
+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:
