2017-06-20mem: Replace EventWrapper use with EventFunctionWrapperSean Wilson
NOTE: With this change there is a possibility for `DRAMCtrl::Rank`s event names to not properly match the rank they were generated by. This could occur if the public rank member is modified after the Rank's construction. A patch would mean refactoring Rank and `DRAMCtrl`b to privatize many of the members of Rank behind getters.

2016-07-01mem: different HMC configurationAbdul Mutaal Ahmad
In this new hmc configuration we have used the existing components in gem5 mainly [SerialLink] [NoncoherentXbar]& [DRAMCtrl] to define 3 different architecture for HMC. Highlights 1- It explores 3 different HMC architectures 2- It creates 4-HMC crossbars and attaches 16 vault controllers with it. This will connect vaults to serial links 3- From the previous version, HMCController with round robin funtionality is being removed and all the serial links are being accessible directly from user ports 4- Latency incorporated by HMCController (in previous version) is being added to SerialLink Committed by Jason Lowe-Power <jason@lowepower.com>

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>
