    How to disable Data Direct I/O (DDIO) on Intel Xeon E5?


      I'm wondering whether it's possible to disable Intel Data Direct I/O on Xeon E5 processor. It'e mentioned that "Intel DDIO is enabled by default on all Intel Xeon processor E5 family and Intel Xeon processor E7 v2 family platforms." in http://www.intel.com/content/www/us/en/io/data-direct-i-o-technology.html but I couldn't find any documents saying how to disable DDIO.
