2013-06-28 Thread mrhines
From: "Michael R. Hines" As requested, the protocol now includes memory unpinning support. This has been implemented in a non-optimized manner, in such a way that one could devise an LRU or other workload-specific information on top of the basic mechanism to influence the way unpinning happens du
