2012-01-17	Ruby: Change the access permissions for MOESI hammer	Andreas Hansson
	Regression statistics update.
2012-01-17	Ruby: Change the access permissions for MOESI hammer	Andreas Hansson
	This patch changes the access permission for the WB_E_W state from Busy to Read_Write to avoid having issues in follow-on patches with functional accesses going through Ruby. This change was made after consultation with all involved parties and is more of a work-around than a fix.
2012-01-17	MEM: Add the system port as a central access point	Andreas Hansson
	The system port is used as a globally reachable access point to the memory subsystem. The benefit of using an actual port is that the usual infrastructure is used to resolve any access and thus makes the overall system able to handle distributed memories in any configuration, and also makes the accesses agnostic to the address map. This patch only introduces the port and does not actually use it for anything.
2012-01-17	MEM: Differentiate functional cache accesses from CPU and memory	Andreas Hansson
	This patch changes the functionalAccess member function in the cache model such that it is aware of what port the access came from, i.e. if it came from the CPU side or from the memory side. By adding this information, it is possible to respect the 'forwardSnoops' flag for snooping requests coming from the memory side and not forward them. This fixes an outstanding issue with the IO bus getting accesses that have no valid destination port and also cleans up future changes to the bus model.
2012-01-16	stats: undo parser change from initparam change	Ali Saidi

2012-01-16	Alpha: warn_once about broken PAL breakpoints.	Steve Reinhardt
	A recent changeset (aae12ce9f34c) removed support for PAL-mode breakpoints in Alpha, since it was awkward and likely unused. This patch lets a user know if they potentially run into this limitation.
2012-01-16	debug: fix AllFlags::disable()	Steve Reinhardt
	Looks like copy-and-paste bug, apparently I'm the first person to ever use this since it's plainly broken.
2012-01-12	inorder: MDU deadlock fix	Maximilien Breughe

2012-01-12	mips: compatibility between MIPS_SE and cross compiler from CodeSorcery	Deyuan Guo

2012-01-12	mips: Fix bugs in faults.cc/hh and tlb.cc for MIPS_FS	Deyuan Guo

2012-01-12	mips: Fix decoder of two float-convert instructions	Deyuan Guo

2012-01-12	mips: definition of MIPS64_QNAN in registers.hh	Deyuan Guo

2012-01-12	PerfectCacheMemory: Remove references to CacheMsg	Nilay 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.
2012-01-11	Packet: Put back part of the assert	Ali Saidi

2012-01-11	Packet: Remove meaningless assert statement	Ali Saidi

2012-01-11	Ruby: Use map option for selecting b/w sparse and memory vector	Nilay Vaish

2012-01-11	Config: Add support for restoring using a timing CPU	Nilay Vaish
	Currently there is an assumption that restoration from a checkpoint will happen by first restoring to an atomic CPU and then switching to a timing CPU. This patch adds support for directly restoring to a timing CPU. It adds a new option '--restore-with-cpu' which is used to specify the type of CPU to which the checkpoint should be restored to. It defaults to 'atomic' which was the case before.
2012-01-11	Ruby: Resurrect Cache Warmup Capability	Nilay 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.
2012-01-11	Ruby Debug Flags: Remove one, add another	Nilay Vaish
	The flag RubyStoreBuffer is being removed, instead RubySystem is being added
2012-01-11	Ruby Port: Add a list of cpu ports attached to this port	Nilay Vaish

2012-01-11	Ruby EventQueue: Remove unused functions	Nilay Vaish

2012-01-11	Ruby Sparse Memory: Add function for collating blocks	Nilay 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.
2012-01-11	Ruby: Add infrastructure for recording cache contents	Nilay Vaish
	This patch changes CacheRecorder, CacheMemory, CacheControllers so that the contents of a cache can be recorded for checkpointing purposes.
2012-01-11	Ruby Memory Vector: Functions for collating and populating pages	Nilay 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.
2012-01-10	Ruby: remove the files related to the tracer	Nilay 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.
2012-01-10	hgfilesize: skip files that have been removed	Nathan Binkert

2012-01-10	MOESI Hammer: Update regression test output	Nilay Vaish

2012-01-10	MOESI Hammer: Remove a couple of bugs	Nilay Vaish
	A couple of bugs were observed while building checkpointing support in Ruby. This patch changes transitions to remove those errors.
2012-01-10	Sparse Memory: Simplify the structure for an entry	Nilay 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.
2012-01-10	Automated merge with ssh://repo.gem5.org/gem5	Ali Saidi

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

2012-01-09	Config: Fix issue with JSON output	Ali Saidi

2012-01-09	Packet: Add derived class FunctionalPacket to enable partial functional reads	Geoffrey 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.
2012-01-09	stats: 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.
2012-01-09	sim: 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.
2012-01-09	O3: Remove some asserts that no longer seem to be valid.	Ali Saidi

2012-01-09	config: support outputing a pickle of the configuration tree	Ali Saidi

2012-01-09	mem: 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.
2012-01-09	O3: Add support of function tracing with O3 CPU.	Ali Saidi

2012-01-09	ARM: Add support for running multiple systems	Ali Saidi

2012-01-09	stats: Update stats for ARM init param changes.	Ali Saidi

2012-01-09	ARM: Add support for initparam m5 op	Ali Saidi

2012-01-09	Base: Fixed shift amount in genrand() to work with large numbers	Dam 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.
2012-01-09	cpu2000: Add missing art benchmark to all	Ali Saidi

2012-01-09	SWIG: Make gem5 compile and link with swig 2.0.4	Andreas 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.
