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The Ruby Tracer is out of date with the changes that are being carried out to support checkpointing.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.

2012-01-10config: Fix json output for Python lt 2.6.Ali Saidi

2012-01-09CPU: Remove Alpha-specific PC alignment check.Anders Handler
2012-01-09Config: Fix issue with JSON outputAli Saidi
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.
2012-01-09stats: fix Vector2d to display stats correctly when y_subname is not specified.Dam Sunwoo
Vector2d stats with no y_subname were not displayed as the VectorPrint subname was not initialized correctly to reflect the empty field.
2012-01-09sim: Enable sampling of run-time for code-sections marked using pseudo insts.Prakash Ramrakhyani
This patch adds a mechanism to collect run time samples for specific portions of a benchmark, using work_begin and work_end pseudo instructions.It also enhances the histogram stat to report geometric mean.
2012-01-09O3: Remove some asserts that no longer seem to be valid.Ali Saidi
2012-01-09config: support outputing a pickle of the configuration treeAli Saidi
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.
2012-01-09O3: Add support of function tracing with O3 CPU.Ali Saidi
2012-01-09ARM: Add support for running multiple systemsAli Saidi
2012-01-09ARM: Add support for initparam m5 opAli Saidi
2012-01-09Base: Fixed shift amount in genrand() to work with large numbersDam Sunwoo
The previous version didn't work correctly with max integer values (2^31-1 for 32-bit, 2^63-1 for 64bit version), causing "shift" to become -1. For smaller numbers, it wouldn't have caused functional errors, but would have resulted in more than necessary loops in the while loop. Special-cased cases when (max + 1 == 0) to prevent the ceilLog2 functions from failing.
2012-01-09SWIG: Make gem5 compile and link with swig 2.0.4Andreas Hansson
To make gem5 compile and run with swig 2.0.4 a few minor fixes are necessary, the fail label issues by swig must not be treated as an error by gcc (tested with gcc 4.2.1), and the vector wrappers must have SWIGPY_SLICE_ARG defined which happens in pycontainer.swg, included through std_container.i. By adding the aforementioned include to the vector wrappers everything seems to work.
2012-01-09MAC: Make gem5 compile and run on MacOSX 10.7.2Andreas Hansson
Adaptations to make gem5 compile and run on OSX 10.7.2, with a stock gcc 4.2.1 and the remaining dependencies from macports, i.e. python 2.7,.2 swig 2.0.4, mercurial 2.0. The changes include an adaptation of the SConstruct to handle non-library linker flags, and Darwin-specific code to find the memory usage of gem5. A number of Ruby files relied on ambigious uint (without the 32 suffix) which caused compilation errors.

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
2012-01-05eventq: add a function for replacing head of the queueNilay Vaish
This patch adds a function for replacing the event at the head of the queue with another event. This helps in running a different set of events. Events already scheduled can processed by replacing the original head event back. This function has been specifically added to support cache warmup and cooldown required for creating and restoring checkpoints. --HG-- extra : rebase_source : ed6e2905720b6bfdefd020fab76235ccf33d28d1
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
2012-01-05X86 TLB: Move a DPRINTF to its correct placeNilay Vaish
The DPRINTF for doing protection checks appears after the checks have been carried out. It is possible that the function returns while the checks are being carried, in which case the printf is missed out. This patch moves the DPRINTF before the checks. --HG-- extra : rebase_source : 172896057e593022444d882ea93323a5d9f77a89
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

2011-12-01VNC: Add support for capturing frame buffer to file each time it is changed.Chris Emmons
When a change in the frame buffer from the VNC server is detected, the new frame is stored out to the m5out/frames_*/ directory. Specifiy the flag "--frame-capture" when running configs/example/fs.py to enable this behavior. --HG-- extra : rebase_source : d4e08e83f4fa6ff79f3dc9c433fc1f0487e057fc

2011-12-01O3: Remove hardcoded tgts_per_mshr in O3CPU.py.Chander Sudanthi
There are two lines in O3CPU.py that set the dcache and icache tgts_per_mshr to 20, ignoring any pre-configured value of tgts_per_mshr. This patch removes these hardcoded lines from O3CPU.py and sets the default L1 cache mshr targets to 20. --HG-- extra : rebase_source : 6f92d950e90496a3102967442814e97dc84db08b
2011-12-01Device: Make changes necessary to support a coherent page walker cache.Mitchell Hayenga
Adds the flag 'recvSnoops' which enables pagewalkers using DmaPorts, to properly configure snoops. --HG-- extra : rebase_source : 64207bef62c3268ddff2236ee4adae873812325f

2011-12-01ARM: Add IsSerializeAfter and IsNonSpeculative flag to the syscall instruction .Ali Saidi
Squashes the subsequent instructions in O3 pipe after the service call, so that they see the effect of the system call when re-executed. This isn't really an issue with FS mode, but can show up in SE mode. --HG-- extra : rebase_source : 613a69fe1d9834261e25a8cd340aa6b47578e1fe

2011-11-28SPARC: Fixing a minor copy-paste bug using the wrong variableAndreas Hansson
There was a bug in the mm_disk implementation where a copy paste error resulted in the d32 variable not being initialised (as it incorrectly was used instead of d16), and gcc 4.5 complaining. --HG-- extra : rebase_source : 9515e87b188b9eac189da8034cb13c3bf7d9e20b
