2014-09-01ruby: move files from ruby/system to ruby/structuresNilay Vaish
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
2012-10-15ruby: improved support for functional accessesNilay Vaish
This patch adds support to different entities in the ruby memory system for more reliable functional read/write accesses. Only the simple network has been augmented as of now. Later on Garnet will also support functional accesses. The patch adds functional access code to all the different types of messages that protocols can send around. These messages are functionally accessed by going through the buffers maintained by the network entities. The patch also rectifies some of the bugs found in coherence protocols while testing the patch. With this patch applied, functional writes always succeed. But functional reads can still fail.
2012-09-18ruby: avoid using g_system_ptr for event schedulingNilay Vaish
This patch removes the use of g_system_ptr for event scheduling. Each consumer object now needs to specify upfront an EventManager object it would use for scheduling events. This makes the ruby memory system more amenable for a multi-threaded simulation.
2012-09-05Ruby Memory Controller: Fix clockingJoel Hestness
2012-07-12Ruby: remove config information from ruby.statsNilay Vaish
This patch removes printConfig() functions from all structures in Ruby. Most of the information is already part of config.ini, and where ever it is not, it would become in due course.
2012-07-10ruby: tag and data cache access supportJoel Hestness
Updates to Ruby to support statistics counting of cache accesses. This feature serves multiple purposes beyond simple stats collection. It provides the foundation for ruby to model the cache tag and data arrays as physical resources, as well as provide the necessary input data for McPAT power modeling.
2012-07-10ruby: adds reset function to Ruby memory controllersNuwan Jayasena
2012-07-10ruby: memory controllers now inherit from an abstract "MemoryControl" classNuwan Jayasena
2012-04-06sim-ruby: checkpointing fixes and dependent eventq improvementsBrad Beckmann
Fixes checkpointing with respect to lost events after swapping event queues. Also adds DPRINTFs to better understand what's going on when Ruby serializes and unserializes.
2011-12-31Ruby: Shuffle some of the included filesNilay Vaish
This patch adds and removes included files from some of the files so as to organize remove some false dependencies and include some files directly instead of transitively. --HG-- extra : rebase_source : 09b482ee9ae00b3a204ace0c63550bc3ca220134
2011-05-05ruby: use RubyMemory flag & remove setDebug() functionalityKorey Sewell
The RubyMemory flag wasnt used in the code, creating large gaps in trace output. Replace cprintfs w/dprintfs using RubyMemory in memory controller. DPRINTF also deprecate the usage of the setDebug() pure virtual function in the AbstractMemoryOrCache Class as well the m_debug/cprintf functions in MemoryControl.hh/cc
2010-06-10ruby: get rid of the Map classNathan Binkert
2010-06-10ruby: get rid of RefCnt and Allocator stuff use base/refcnt.hhNathan Binkert
This was somewhat tricky because the RefCnt API was somewhat odd. The biggest confusion was that the the RefCnt object's constructor that took a TYPE& cloned the object. I created an explicit virtual clone() function for things that took advantage of this version of the constructor. I was conservative and used clone() when I was in doubt of whether or not it was necessary. I still think that there are probably too many instances of clone(), but hopefully not too many. I converted several instances of const MsgPtr & to a simple MsgPtr. If the function wants to avoid the overhead of creating another reference, then it should just use a regular pointer instead of a ref counting ptr. There were a couple of instances where refcounted objects were created on the stack. This seems pretty dangerous since if you ever accidentally make a reference to that object with a ref counting pointer, bad things are bound to happen.
2010-04-02ruby: get "using namespace" out of headersNathan Binkert
In addition to obvious changes, this required a slight change to the slicc grammar to allow types with :: in them. Otherwise slicc barfs on std::string which we need for the headers that slicc generates.

2010-01-29ruby: cleaned up ruby profilersBrad Beckmann
Cleaned up the ruby profilers by moving the memory controller profiling code out of the main profiler object and into a separate object similar to the current CacheProfiler. Both the CacheProfiler and MemCntrlProfiler are specific to a particular Ruby object, CacheMemory and MemoryControl respectively. Therefore, these profilers should not be SimObjects and created by the python configuration system, but instead private objects. This simplifies the creation of these profilers.
2010-01-29ruby: Memory Controller Profiler with new config systemBrad Beckmann
This patch includes a rather substantial change to the memory controller profiler in order to work with the new configuration system. Most noteably, the mem_cntrl_profiler no longer uses a string map, but instead a vector. Eventually this support should be removed from the main profiler and go into a separate object. Each memory controller should have a pointer to that new mem_cntrl profile object.
2010-01-29ruby: Convert most Ruby objects to M5 SimObjects.Steve Reinhardt
The necessary companion conversion of Ruby objects generated by SLICC are converted to M5 SimObjects in the following patch, so this patch alone does not compile. Conversion of Garnet network models is also handled in a separate patch; that code is temporarily disabled from compiling to allow testing of interim code.
2009-07-06ruby: apply some fixes that were overwritten by the recent ruby import.Nathan Binkert
2009-07-06ruby: Import the latest ruby changes from gems.Nathan Binkert
This was done with an automated process, so there could be things that were done in this tree in the past that didn't make it. One known regression is that atomic memory operations do not seem to work properly anymore.
2009-07-06ruby: replace strings that were missed in original ruby import.Nathan Binkert
2009-05-12ruby: deal with printf warnings and convert some to cprintfNathan Binkert
2009-05-11ruby: clean up a few warningsNathan Binkert
2009-05-11ruby: Make ruby #includes use full paths to the files they're including.Nathan Binkert
This basically means changing all #include statements and changing autogenerated code so that it generates the correct paths. Because slicc generates #includes, I had to hard code the include paths to mem/protocol.
2009-05-11ruby: Import ruby and slicc from GEMSNathan Binkert
We eventually plan to replace the m5 cache hierarchy with the GEMS hierarchy, but for now we will make both live alongside eachother.
