2012-01-12PerfectCacheMemory: Remove references to CacheMsgNilay Vaish
The definition for the class CacheMsg was removed long back. Some declaration had still survived, which was recently removed. Since the PerfectCacheMemory class relied on this particular declaration, its absence let to compilation breaking down. Hence this patch.

2012-01-11Ruby: Resurrect Cache Warmup CapabilityNilay Vaish
This patch resurrects ruby's cache warmup capability. It essentially makes use of all the infrastructure that was added to the controllers, memories and the cache recorder.
2012-01-11Ruby Debug Flags: Remove one, add anotherNilay Vaish
The flag RubyStoreBuffer is being removed, instead RubySystem is being added
2012-01-11Ruby Port: Add a list of cpu ports attached to this portNilay Vaish
2012-01-11Ruby EventQueue: Remove unused functionsNilay Vaish
2012-01-11Ruby Sparse Memory: Add function for collating blocksNilay Vaish
This patch adds function to the Sparse Memory so that the blocks can be recorded in a cache trace. The blocks are added to the cache recorder which can later write them into a file.
2012-01-11Ruby: Add infrastructure for recording cache contentsNilay Vaish
This patch changes CacheRecorder, CacheMemory, CacheControllers so that the contents of a cache can be recorded for checkpointing purposes.
2012-01-11Ruby Memory Vector: Functions for collating and populating pagesNilay Vaish
This patch adds functions to the memory vector class that can be used for collating memory pages to raw trace and for populating pages from a raw trace.
2012-01-10Ruby: remove the files related to the tracerNilay Vaish
The Ruby Tracer is out of date with the changes that are being carried out to support checkpointing. Hence, it needs to be removed.
2012-01-10MOESI Hammer: Remove a couple of bugsNilay Vaish
A couple of bugs were observed while building checkpointing support in Ruby. This patch changes transitions to remove those errors.
2012-01-10Sparse Memory: Simplify the structure for an entryNilay Vaish
The SparseMemEntry structure includes just one void* pointer. It seems unnecessary that we have a structure for this. The patch removes the structure and makes use of a typedef on void* instead.
2012-01-09Packet: Add derived class FunctionalPacket to enable partial functional readsGeoffrey Blake
This adds the derived class FunctionalPacket to fix a long standing deficiency in the Packet class where it was unable to handle finding data to partially satisfy a functional access. Made this a derived class as functional accesses are used only in certain contexts and to not add any additional overhead to the existing Packet class.
2012-01-09mem: Change DPRINTF prints more useful destination port number.Min Kyu Jeong
Old code prints 0 for destination since pkt->getDest() returns 0 for pkt->getDest() == Packet::Broadcast, which is always true.

2012-01-06Ruby Set: Move NUMBER_WORDS_PER_SET to Set.hhNilay Vaish
This constant is currently in System.hh, but is only used in Set.hh. It is being moved to Set.hh to remove this artificial dependence of Set.hh on System.hh. --HG-- extra : rebase_source : 683c43a5eeaec4f5f523b3ea32953a07f65cfee7
2012-01-05MESI Coherence Protocol: Fix L2 miss statisticsNilay Vaish
This patch removes calls to uu_ProfileMiss from transitions where the request is satisfied by the L2 cache controller. --HG-- extra : rebase_source : e59fe7c6cd5795c0019cf178dd3b062d73cc2ff5
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
2011-12-31SLICC: Use pointers for directory entriesNilay Vaish
SLICC uses pointers for cache and TBE entries but not for directory entries. This patch changes the protocols, SLICC and Ruby memory system so that even directory entries are referenced using pointers. --HG-- extra : rebase_source : abeb4ac78033d003153751f216fd1948251fcfad

2011-11-18SE/FS: Get rid of includes of config/full_system.hh.Gabe Black
2011-11-14Ruby: Process packet instead of RubyRequest in SequencerNilay Vaish
This patch changes the implementation of Ruby's recvTiming() function so that it pushes a packet in to the Sequencer instead of a RubyRequest. This requires changes in the Sequencer's makeRequest() and issueRequest() functions, as they also need to operate on a Packet instead of RubyRequest.
2011-11-07SE/FS: Get rid of FULL_SYSTEM in mem.Gabe Black
2011-11-04GARNET: adding a fault model for resilient on-chip network research.Tushar Krishna
This patch adds a fault model, which provides the probability of a number of architectural faults in the interconnection network (e.g., data corruption, misrouting). These probabilities can be used to realistically inject faults in GARNET and faithfully evaluate the effectiveness of novel resilient NoC architectures.

2011-11-03Protocol: Remove standard one and two level filesNilay Vaish
2011-11-03Ruby: Remove some unused typedefsNilay Vaish
This patch removes some of the unused typedefs. It also moves some of the typedefs from Global.hh to TypeDefines.hh. The patch also eliminates the file NodeID.hh.
2011-10-31GCC: Get everything working with gcc 4.6.1.Gabe Black

2011-10-28Ruby: Reorganize mapping of componentsNilay Vaish
In RubySlicc_ComponentMapping.hh, certain '#define's have been used for mapping MachineType to GenericMachineType. These '#define's are being eliminated and the code will now be generated by SLICC instead. Also are being eliminated some of the unused functions from RubySlicc_ComponentMapping.sm.
2011-10-22SE: move page allocation from PageTable to ProcessSteve Reinhardt
PageTable supported an allocate() call that called back through the Process to allocate memory, but did not have a method to map addresses without allocating new pages. It makes more sense for Process to do the allocation, so this method was renamed allocateMem() and moved to Process, and uses a new map() call on PageTable. The remaining uses of the process pointer in PageTable were only to get the name and the PID, so by passing these in directly in the constructor, we can make PageTable completely independent of Process.
2011-10-22syscall_emul: implement MAP_FIXED option to mmap()Steve Reinhardt

2011-09-22event: minor cleanupSteve Reinhardt
Initialize flags via the Event constructor instead of calling setFlags() in the body of the derived class's constructor. I forget exactly why, but this made life easier when implementing multi-queue support. Also rename Event::getFlags() to isFlagSet() to better match common usage, and get rid of some unused Event methods.
2011-09-13Mem: Allow ASID to be set after request is created.Daniel Johnson
2011-09-13Prefetch: Don't prefetch if address is in the write queue.Ali Saidi
Check that we're not currently writing back an address the prefetcher is trying to prefetch before issuing it. We previously checked the mshrQueue and the cache itself, but forgot to check the writeBuffer. This fixes a memory corrucption issue with an L2 prefetcher.
2011-09-09Stack: Tidy up some comments, a warning, and make stack extension consistent.Gabe Black
Do some minor cleanup of some recently added comments, a warning, and change other instances of stack extension to be like what's now being done for x86.
