Hi, I just found the following information, in the datasheet of each Intel® chipset there are some references for "peer-to-peer", but for more information about how to use this feature, will be better to get a hold of our Embedded Design Center area at: http://www.intel.com/content/www/us/en/embedded/embedded-design-center.html
See the 7 series chipset datasheet at:
In page 128 titled: 5.1.5 Peer Cycles, also in page 387 under title: 9.4 Memory Map, those are some references about "peer-to-peer".
Also in the 100 Series chipset datasheet available at: http://www.intel.com/content/www/us/en/chipsets/100-series-chipset-datasheet-vol-1.html, on page 33 under 4.3 Memory Map some other information.
Hope this helps.
