2015-12-31mem: Make cache terminology easier to understandAndreas Hansson
This patch changes the name of a bunch of packet flags and MSHR member functions and variables to make the coherency protocol easier to understand. In addition the patch adds and updates lots of descriptions, explicitly spelling out assumptions. The following name changes are made: * the packet memInhibit flag is renamed to cacheResponding * the packet sharedAsserted flag is renamed to hasSharers * the packet NeedsExclusive attribute is renamed to NeedsWritable * the packet isSupplyExclusive is renamed responderHadWritable * the MSHR pendingDirty is renamed to pendingModified The cache states, Modified, Owned, Exclusive, Shared are also called out in the cache and MSHR code to make it easier to understand.
2015-11-03mem: hmc: serial link modelErfan Azarkhish
This changeset adds a serial link model for the Hybrid Memory Cube (HMC). SerialLink is a simple variation of the Bridge class, with the ability to account for the latency of packet serialization. Also trySendTiming has been modified to correctly model bandwidth. Committed by: Nilay Vaish <nilay@cs.wisc.edu>
