2018-07-23	mem: Rename Packet::checkFunctional to trySatisfyFunctional	Robert Kovacsics
	Packet::checkFunctional also wrote data to/from the packet depending on if it was read/write, respectively, which the 'check' in the name would suggest otherwise. This renames it to doFunctional, which is more suggestive. It also renames any function called checkFunctional which calls Packet::checkFunctional. These are - Bridge::BridgeMasterPort::checkFunctional - calls Packet::checkFunctional - MSHR::checkFunctional - calls Packet::checkFunctional - MSHR::TargetList::checkFunctional - calls Packet::checkFunctional - Queue<>::checkFunctional (of src/mem/cache/queue.hh, not src/cpu/minor/buffers.h) - Instantiated with Queue<WriteQueueEntry> and Queue<MSHR> - WriteQueueEntry - calls Packet::checkFunctional - WriteQueueEntry::TargetList - calls Packet::checkFunctional - MemDelay::checkFunctional - calls QueuedSlavePort/QueuedMasterPort::checkFunctional - Packet::checkFunctional - PacketQueue::checkFunctional - calls Packet::checkFunctional - QueuedSlavePort::checkFunctional - calls PacketQueue::doFunctional - QueuedMasterPort::checkFunctional - calls PacketQueue::doFunctional - SerialLink::SerialLinkMasterPort::checkFunctional - calls Packet::doFunctional Change-Id: Ieca2579c020c329040da053ba8e25820801b62c5 Reviewed-on: https://gem5-review.googlesource.com/11810 Reviewed-by: Daniel Carvalho <odanrc@yahoo.com.br> Reviewed-by: Jason Lowe-Power <jason@lowepower.com> Maintainer: Jason Lowe-Power <jason@lowepower.com>

2018-05-31	mem-cache: Adopt a more sensible cache class hierarchy	Nikos Nikoleris
	This patch changes what goes into the BaseCache and what goes into the Cache, to make it easier to add a NoncoherentCache with as much re-use as possible. A number of redundant members and definitions are also removed in the process. This is a modified version of a changeset put together by Andreas Hansson <andreas.hansson@arm.com> Change-Id: Ie9dd73c4ec07732e778e7416b712dad8b4bd5d4b Reviewed-on: https://gem5-review.googlesource.com/10431 Reviewed-by: Daniel Carvalho <odanrc@yahoo.com.br> Maintainer: Nikos Nikoleris <nikos.nikoleris@arm.com>

2017-12-05	mem: Add support for WriteClean packets in the memory system	Nikos Nikoleris
	This change adds support for creating and handling WriteClean packets. The WriteClean operation is almost identical to a WritebackDirty with the exception that the cache generating a WriteClean retains a copy of the block.

2016-04-21	mem: Deallocate all write-queue entries when sent	Andreas Hansson
	This patch removes the write-queue entry tracking previously used for uncacheable writes. The write-queue entry is now deallocated as soon as the packet is sent. As a result we also forego the stats for uncacheable writes. Additionally, there is no longer a need to attach the write-queue entry to the packet.
2016-03-17	mem: Create a separate class for the cache write buffer	Andreas Hansson
	This patch breaks out the cache write buffer into a separate class, without affecting any stats. The goal of the patch is to avoid encumbering the much-simpler write queue with the complex MSHR handling. In a follow on patch this simplification allows us to implement write combining. The WriteQueue gets its own class, but shares a common ancestor, the generic Queue, with the MSHRQueue.
