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

2011-12-01ARM: 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

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.
2011-11-09GCC: Guard some gcc flags so they're used when available and needed.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.
2011-11-04MESI Protocol: Add functions for profiling missesNilay Vaish
2011-11-03x86: Add microop for fenceNilay Vaish
This patch adds a new microop for memory barrier. The microop itself does nothing, but since it is marked as a memory barrier, the O3 CPU should flush all the pending loads and stores before the fence to the memory system.
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.
2011-10-30Python: Remove import for randomNilay Vaish
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
2011-10-20dev: clean up PioDevice and DmaDevive getPort() methods.Steve Reinhardt
Make DmaDevice::getPort() call PioDevice::getPort() instead of just copying and pasting the code. Also move definitions from .hh to .cc file.
2011-10-20SimObject: add export_method* hooks to export C++ methods to PythonSteve Reinhardt
Replace the (broken as of previous changeset) swig_objdecl() method that allowed/forced you to substitute a whole new C++ struct definition for SWIG to wrap with a set of export_method* hooks that let you just declare a set of C++ methods (or other declarations) that get inserted in the auto-generated struct. Restore the System get/setMemoryMode methods, and use this mechanism to specialize SimObject as well, eliminating teh need for sim_object.i. Needed bits of sim_object.i are moved to the new pyobject.i. Also sucked a little SimObject specialization into cxx_param_decl() allowing us to get rid of src/sim/sim_object_params.hh. Now the generation and wrapping of the base SimObject param struct is more in line with how derived objects are handled. --HG-- rename : src/python/swig/sim_object.i => src/python/swig/pyobject.i
2011-10-20scons/swig: refactor some of the scons/SWIG codeSteve Reinhardt
- Move the random bits of SWIG code generation out of src/SConscript file and into methods on the objects being wrapped. - Cleaned up some variable naming and added some comments to make the process a little clearer. - Did a little generated file/module renaming: - vptype_Foo now Foo_vector - init_Foo is now Foo_init This makes it easier to see all the Foo-related files in a sorted directory listing. - Made cxx_predecls and swig_predecls normal SimObject classmethods. - Got rid of swig_objdecls hook, even though this breaks the System objects get/setMemoryMode method exports. Will be fixing this in a future changeset.

2011-10-10mc146818: Correctly serialize tickEventNilay Vaish
'tickEvent' was not being serialized as in its place 'event' was being used. This patch rectifies this error.
2011-09-27O3: Tidy up some DPRINTFs in the LSQ.Gabe Black
2011-09-27Faults: Replace calls to genMachineCheckFault with M5PanicFault.Gabe Black
2011-09-27Faults: Add in generic faults that work like panics, warns, etc.Gabe Black
These faults take varargs to their constructors which they print into a string and pass to the M5DebugFault base class. They are basically faults wrapped around panics, faults, warns, and warnonce-es so that they happen only at commit.
2011-09-27Faults: Make the generic faults more consistent between SE and FS.Gabe Black
All of the classes will now be available in both modes, and only GenericPageTableFault will continue to check the mode for conditional compilation. It uses a process object to handle the fault in SE mode, and for now those aren't available in FS mode.
2011-09-26ISA parser: Use '_' instead of '.' to delimit type modifiers on operands.Gabe Black
By using an underscore, the "." is still available and can unambiguously be used to refer to members of a structure if an operand is a structure, class, etc. This change mostly just replaces the appropriate "."s with "_"s, but there were also a few places where the ISA descriptions where handling the extensions themselves and had their own regular expressions to update. The regular expressions in the isa parser were updated as well. It also now looks for one of the defined type extensions specifically after connecting "_" where before it would look for any sequence of characters after a "." following an operand name and try to use it as the extension. This helps to disambiguate cases where a "_" may legitimately be part of an operand name but not separate the name from the type suffix. Because leaving the "_" and suffix on the variable name still leaves a valid C++ identifier and all extensions need to be consistent in a given context, I considered leaving them on as a breadcrumb that would show what the intended type was for that operand. Unfortunately the operands can be referred to in code templates, the Mem operand in particular, and since the exact type of Mem can be different for different uses of the same template, that broke things.
2011-09-26LSQ: Moved a couple of lines to enable O3 + RubyNilay Vaish
This patch makes O3 CPU work along with the Ruby memory model. Ruby overwrites the senderState pointer with another pointer. The pointer is restored only when Ruby gets done with the packet. LSQ makes use of senderState just after sendTiming() returns. But the dynamic_cast returns a NULL pointer since Ruby's senderState pointer is from a different class. Storing the senderState pointer before calling sendTiming() does away with the problem.
2011-09-26SE/FS: Define a const bool FullSystem which will equal FULL_SYSTEM.Gabe Black
This constant will have the same value as FULL_SYSTEM but will not be usable by the preprocessor. It can be substituted into places where FULL_SYSTEM is used in a C++ context and will make it easier to find which parts of the simulator still use FULL_SYSTEM with the preprocessor using grep.
2011-09-24SCons: Add a comment I forgot to add in earlier.Gabe Black
This comment was supposed to be added to an earlier change as part of review feedback, but I accidentally left it out when I pushed. Add it in now.
2011-09-24SCons: Make the ISA parser a source for its output files like the comments say.Gabe Black
There was a change a while ago that refactored some scons stuff which got rid of cpu_models.py but also accidentally got rid of the ISA parser as a source for its target files. That meant that changes which affected the parser wouldn't cause a rebuild unless they also changed one of the description files. This change fixes that.
2011-09-23X86: Move the MSR lookup table out of the TLB and into its own file.Gabe Black
Translating MSR addresses into MSR register indices took a lot of space in the TLB source and made looking around in that file awkward. This change moves the lookup into its own file to get it out of the way. It also changes it from a switch statement to a hash map which should hopefully be a little more efficient.
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.
2011-09-22pseudo_inst: clean up workbegin/workend functionsSteve Reinhardt
Use exitSimLoop() function instead of explicitly scheduling on mainEventQueue (which won't work once we go to multiple event queues). Also introduced a local params variable to shorten a lot of expressions.
2011-09-22params.py: enhance IpAddress param handlingSteve Reinhardt
Print IpAddress params in dot notation for readability. Properly compare IpAddress objects (by value and not object identity). Also fix up derived param classes (IpNetmask and IpWithPort) similarly.
2011-09-19MIPS: Final overhaul of MIPS faults to kill #if FULL_SYSTEMGabe Black
This change is a significant reorganization of the MIPS fault code that gets rid of duplication, fixes some bugs, doubtlessly introduces others, and adds names for the exception code constants.
