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.
2012-01-07Ruby Cache: Add param for marking caches as instruction onlyNilay Vaish

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

2011-11-14Ruby: 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.
2011-11-04GARNET: 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.
2011-11-04MESI Protocol: Add functions for profiling missesNilay Vaish
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
And by "everything" I mean all the quick regressions.
2011-10-28Merged with recent changes.Nilay Vaish
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.
2011-09-01Fix build for gcc-4.2 opt/fastLisa Hsu
Even though the code is safe, compiler flags a warning here, which are treated as errors for fast/opt. I know it's redundant but it has no side effects and fixes the compile.
2011-09-01Functional Accesses: Update states to support Broadcast/Snooping protocols.Lisa Hsu
In the current implementation of Functional Accesses, it's very hard to implement broadcast or snooping protocols where the memory has no idea if it has exclusive access to a cache block or not. Without this knowledge, making sure the RW vs. RO permissions are right are next to impossible. So we add a new state called Backing_Store to enable the conveyance that this is the backup storage for a block, so that it can be written if it is the only possibly RW block in the system, or written even if there is another RW block in the system, without causing problems. Also, a small change to actually set the m_name field for each Controller so that debugging can be easier. Now you can access a controller's name just by controller->getName().
2011-08-29SLICC: Pass arguments by referenceNilay Vaish
Arguments to functions were being passed by value. This patch changes SLICC so that arguments are passed by reference.
2011-08-29Ruby: Remove some unused codeNilay Vaish
2011-08-26Ruby: Eliminate modulo op for computing set size.Nilay Vaish
2011-08-19Mem: Put prefetcher notify call before packet is deleted.Ali Saidi
2011-08-19Prefetcher: Fix some memory leaks with the prefetcher.Ali Saidi
2011-08-15Ruby: Initialize some variables.Nilay Vaish
2011-08-08BuildEnv: Eliminate RUBY as build environment variableNilay Vaish
This patch replaces RUBY with PROTOCOL in all the SConscript files as the environment variable that decides whether or not certain components of the simulator are compiled.
2011-08-03Ruby: Remove files and includes not in useNilay Vaish
2011-08-02Scons: Make some Action objects fit the abreviated output format.Gabe Black
2011-08-02Scons: Drop RUBY as compile time option.Nilay Vaish
This patch drops RUBY as a compile time option. Instead the PROTOCOL option is used to figure out whether or not to build Ruby. If the specified protocol is 'None', then Ruby is not compiled.
2011-07-27SLICC: Put functions of a controller in its .cc fileNilay Vaish
Currently, functions associated with a controller go into separate files. This patch puts all the functions in the controller's .cc file. This should hopefully take away some time from compilation.
2011-07-15Mem: Fix issue with prefetches originating at non-L1 caches getting stale dataAli Saidi
Prefetch requests issued from the L2 or below wouldn't check if valid data is present higher in the system. If a prefetch into the L2 occured at the same time as writeback from a higher-level cache the dirty data could be replaced in by unmodified data in memory.

2011-07-06MOESI_hammer: Fixed uniprocessor DMA bugBrad Beckmann
2011-07-05slicc: add a protocol statement and an include statementNathan Binkert
All protocols must specify their name The include statement allows any file to include another file.
2011-07-05slicc: cleanup slicc code and make it less verboseNathan Binkert
2011-07-05grammar: better encapsulation of a grammar and parsingNathan Binkert
This makes it possible to use the grammar multiple times and use the multiple instances concurrently. This makes implementing an include statement as part of a grammar possible.
2011-07-03Network_test: Conform it with functional access changes in RubyNilay Vaish
Addition of functional access support to Ruby necessitated some changes to the way coherence protocols are written. I had forgotten to update the Network_test protocol. This patch makes those updates.
2011-07-01Ruby: Commit files missing from previous commitNilay Vaish
The previous commit on functional access support in Ruby did not have some of the files required. This patch adds those files to the repository.
2011-06-30Ruby: Add support for functional accessesBrad Beckmann ext:(%2C%20Nilay%20Vaish%20%3Cnilay%40cs.wisc.edu%3E)
This patch rpovides functional access support in Ruby. Currently only the M5Port of RubyPort supports functional accesses. The support for functional through the PioPort will be added as a separate patch.
