ruby: move files from ruby/system to ruby/structures
The directory ruby/system is crowded and unorganized. Hence, the files the hold actual physical structures, are being moved to the directory ruby/structures. This includes Cache Memory, Directory Memory, Memory Controller, Wire Buffer, TBE Table, Perfect Cache Memory, Timer Table, Bank Array. The directory ruby/systems has the glue code that holds these structures together. --HG-- rename : src/mem/ruby/system/MachineID.hh => src/mem/ruby/common/MachineID.hh rename : src/mem/ruby/buffers/MessageBuffer.cc => src/mem/ruby/network/MessageBuffer.cc rename : src/mem/ruby/buffers/MessageBuffer.hh => src/mem/ruby/network/MessageBuffer.hh rename : src/mem/ruby/buffers/MessageBufferNode.cc => src/mem/ruby/network/MessageBufferNode.cc rename : src/mem/ruby/buffers/MessageBufferNode.hh => src/mem/ruby/network/MessageBufferNode.hh rename : src/mem/ruby/system/AbstractReplacementPolicy.hh => src/mem/ruby/structures/AbstractReplacementPolicy.hh rename : src/mem/ruby/system/BankedArray.cc => src/mem/ruby/structures/BankedArray.cc rename : src/mem/ruby/system/BankedArray.hh => src/mem/ruby/structures/BankedArray.hh rename : src/mem/ruby/system/Cache.py => src/mem/ruby/structures/Cache.py rename : src/mem/ruby/system/CacheMemory.cc => src/mem/ruby/structures/CacheMemory.cc rename : src/mem/ruby/system/CacheMemory.hh => src/mem/ruby/structures/CacheMemory.hh rename : src/mem/ruby/system/DirectoryMemory.cc => src/mem/ruby/structures/DirectoryMemory.cc rename : src/mem/ruby/system/DirectoryMemory.hh => src/mem/ruby/structures/DirectoryMemory.hh rename : src/mem/ruby/system/DirectoryMemory.py => src/mem/ruby/structures/DirectoryMemory.py rename : src/mem/ruby/system/LRUPolicy.hh => src/mem/ruby/structures/LRUPolicy.hh rename : src/mem/ruby/system/MemoryControl.cc => src/mem/ruby/structures/MemoryControl.cc rename : src/mem/ruby/system/MemoryControl.hh => src/mem/ruby/structures/MemoryControl.hh rename : src/mem/ruby/system/MemoryControl.py => src/mem/ruby/structures/MemoryControl.py rename : src/mem/ruby/system/MemoryNode.cc => src/mem/ruby/structures/MemoryNode.cc rename : src/mem/ruby/system/MemoryNode.hh => src/mem/ruby/structures/MemoryNode.hh rename : src/mem/ruby/system/MemoryVector.hh => src/mem/ruby/structures/MemoryVector.hh rename : src/mem/ruby/system/PerfectCacheMemory.hh => src/mem/ruby/structures/PerfectCacheMemory.hh rename : src/mem/ruby/system/PersistentTable.cc => src/mem/ruby/structures/PersistentTable.cc rename : src/mem/ruby/system/PersistentTable.hh => src/mem/ruby/structures/PersistentTable.hh rename : src/mem/ruby/system/PseudoLRUPolicy.hh => src/mem/ruby/structures/PseudoLRUPolicy.hh rename : src/mem/ruby/system/RubyMemoryControl.cc => src/mem/ruby/structures/RubyMemoryControl.cc rename : src/mem/ruby/system/RubyMemoryControl.hh => src/mem/ruby/structures/RubyMemoryControl.hh rename : src/mem/ruby/system/RubyMemoryControl.py => src/mem/ruby/structures/RubyMemoryControl.py rename : src/mem/ruby/system/SparseMemory.cc => src/mem/ruby/structures/SparseMemory.cc rename : src/mem/ruby/system/SparseMemory.hh => src/mem/ruby/structures/SparseMemory.hh rename : src/mem/ruby/system/TBETable.hh => src/mem/ruby/structures/TBETable.hh rename : src/mem/ruby/system/TimerTable.cc => src/mem/ruby/structures/TimerTable.cc rename : src/mem/ruby/system/TimerTable.hh => src/mem/ruby/structures/TimerTable.hh rename : src/mem/ruby/system/WireBuffer.cc => src/mem/ruby/structures/WireBuffer.cc rename : src/mem/ruby/system/WireBuffer.hh => src/mem/ruby/structures/WireBuffer.hh rename : src/mem/ruby/system/WireBuffer.py => src/mem/ruby/structures/WireBuffer.py rename : src/mem/ruby/recorder/CacheRecorder.cc => src/mem/ruby/system/CacheRecorder.cc rename : src/mem/ruby/recorder/CacheRecorder.hh => src/mem/ruby/system/CacheRecorder.hh

-//////////////////////////////////////////////////////////////////////////////
-// This object was written to literally mimic a Wire in Ruby, in the sense
-// that there is no way for messages to get reordered en route on the WireBuffer.
-// With Message Buffers, even if randomization is off and ordered is on,
-// messages can arrive in different orders than they were sent because of
-// network issues. This mimics a Wire, such that that is not possible. This can
-// allow for messages between closely coupled controllers that are not actually
-// separated by a network in real systems to simplify coherence.
