Moved, renamed, and deleted files
The original directory structure was scattered and unorganized.
Changes are basically to make it look like kernel structure.

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/ + +For specific information about kernel-level support, see: + + The Direct Rendering Manager, Kernel Support for the Direct Rendering + Infrastructure + http://dri.sourceforge.net/doc/drm_low_level.html + + Hardware Locking for the Direct Rendering Infrastructure + http://dri.sourceforge.net/doc/hardware_locking_low_level.html + + A Security Analysis of the Direct Rendering Infrastructure + http://dri.sourceforge.net/doc/security_low_level.html |
