2011-11-20	X86: Fix the constant detecting three byte opcodes in the predecoder.	Gabe Black
	--HG-- extra : rebase_source : b64c3d2348cb73177024695fb6e205d51bf1cda9
2011-11-17	Regression: Update statistics for x86 long regression tests	Nilay Vaish
	This patch updates reference statistics for the regression tests. This update was necessitated by a recent change in behavior of some instructions in the x86 architecture.
2011-11-14	Ruby: Process packet instead of RubyRequest in Sequencer	Nilay 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.
2011-11-09	GCC: Guard some gcc flags so they're used when available and needed.	Gabe Black

2011-11-05	Tests: Update stats due to addition of fence microop	Nilay Vaish

2011-11-04	GARNET: 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.
2011-11-04	MESI Protocol: Add functions for profiling misses	Nilay Vaish

2011-11-03	x86: Add microop for fence	Nilay 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.
2011-11-03	Protocol: Remove standard one and two level files	Nilay Vaish

2011-11-03	Ruby: Remove some unused typedefs	Nilay 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.
2011-10-31	GCC: Get everything working with gcc 4.6.1.	Gabe Black
	And by "everything" I mean all the quick regressions.
2011-10-30	Commit due to merge.	Nilay Vaish

2011-10-30	Python: Remove import for random	Nilay Vaish

2011-10-29	Ruby FS: Add the options for kernel and simulation script	Nilay Vaish
	These options were missing from the script ruby_fs.py. This patch adds these options to the script.
2011-10-28	Merged with recent changes.	Nilay Vaish

2011-10-28	Ruby: Reorganize mapping of components	Nilay 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.
2011-10-22	SE: move page allocation from PageTable to Process	Steve 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.
2011-10-22	syscall_emul: implement MAP_FIXED option to mmap()	Steve Reinhardt

2011-10-22	tests: fix spurious scons "Error 1" messages	Steve Reinhardt
	Turns out these are due to diff reporting that files acutally differed via a non-zero exit code.
2011-10-20	dev: 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.
2011-10-20	SimObject: add export_method* hooks to export C++ methods to Python	Steve 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
2011-10-20	scons/swig: refactor some of the scons/SWIG code	Steve 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.
2011-10-19	ARM: Fix small bug in config script that prevents android from booting	Ali Saidi

2011-10-17	scons: fix building of shared objects	Nathan Binkert

2011-10-10	mc146818: Correctly serialize tickEvent	Nilay Vaish
	'tickEvent' was not being serialized as in its place 'event' was being used. This patch rectifies this error.
2011-09-27	O3: Tidy up some DPRINTFs in the LSQ.	Gabe Black

2011-09-27	Faults: Replace calls to genMachineCheckFault with M5PanicFault.	Gabe Black

2011-09-27	Faults: 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.
2011-09-27	Faults: 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.
2011-09-26	ISA 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.
2011-09-26	LSQ: Moved a couple of lines to enable O3 + Ruby	Nilay 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.
2011-09-26	SE/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.
2011-09-24	SCons: 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.
2011-09-24	SCons: 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.
2011-09-24	style.py: don't die on empty files	Steve Reinhardt

2011-09-23	X86: 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.
2011-09-22	event: minor cleanup	Steve 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.
2011-09-22	pseudo_inst: clean up workbegin/workend functions	Steve 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.
2011-09-22	params.py: enhance IpAddress param handling	Steve 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.
2011-09-19	MIPS: Final overhaul of MIPS faults to kill #if FULL_SYSTEM	Gabe 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.
2011-09-19	MIPS, faults: Update how the PC is set.	Gabe Black

2011-09-19	MIPS: Get rid of skipFaultInstruction and setRestartAddress.	Gabe Black
	Neither of these functions were used.
2011-09-19	MIPS: Use inheritance to consolidate class definitions.	Gabe Black

2011-09-19	MIPS: Always compile in setExceptionState, including in SE mode.	Gabe Black
	Also fix the newly exposed and preexisting compile errors. This code hasn't been exposed in a while, and it's not up to date with the rest of gem5.
2011-09-19	MIPS: Consolidate TLB related faults.	Gabe Black
	Pass in a bool to indicate if the fault is from a store instead of having two different classes. The classes were also misleadingly named since loads are also processed by the DTB but should return ITB faults since they aren't stores. The TLB may be returning the wrong fault in this case, but I haven't looked at it closely.
2011-09-19	MIPS: Get rid of the unused "count" field in FaultVals.	Gabe Black

2011-09-19	MIPS: Move the genMachineCheckFault function near MachineCheckFault.	Gabe Black
	Since they're so closely linked, they should be next to each other in the file.
2011-09-19	MIPS: Consolidate the two AddressErrorFault variants.	Gabe Black

2011-09-19	Faults: Get rid of the unused isAlignmentFault and isMachineCheckFault.	Gabe Black
	These functions aren't called anywhere and are probably only theoretically useful.
2011-09-19	MIPS: Get rid of cruft in the fault classes.	Gabe Black
	Get rid of Fault classes left over from when this file was copied from Alpha, and rename ArithmeticOverflowFault to be IntegerOverflowFault and get rid of the old IntegerOverflowFault stub. The Integer version is what's actually in the manual, but the Arithmetic version had the implementation.
