2010-03-21	ruby: Added a mesh network with directories at the corners	Brad Beckmann
	The patch creates a specific mesh network where directories are at the corners. The patch is a good example of how to create an arbitrary network, similar to the old file specified network, while leveraging scripts and loops when possible.

2010-02-26	isa_parser: Make SCons import the isa_parser	Nathan Binkert
	this is instead of forking a new interpreter

2010-02-25	configs: pull out cache configuration code from se.py and fs.py.	Lisa Hsu
	Most of these frontend configurations share cache configuration code, pull it out so that changes to caches don't have to require changing multiple config files.
2010-02-25	stats: update stats for the changes I pushed re: shared cache occupancy	Lisa Hsu

2010-02-24	cache stats: account for writebacks and/or device occupancy in the cache.	Lisa Hsu
	Plus, a minor bugfix that neglects to update blk->contextSrc in certain cases on a cache insert.
2010-02-23	cache: Make caches sharing aware and add occupancy stats.	Lisa Hsu
	On the config end, if a shared L2 is created for the system, it is parameterized to have n sharers as defined by option.num_cpus. In addition to making the cache sharing aware so that discriminating tag policies can make use of context_ids to make decisions, I added an occupancy AverageStat and an occ % stat to each cache so that you could know which contexts are occupying how much cache on average, both in terms of blocks and percentage. Note that since devices have context_id -1, having an array of occ stats that correspond to each context_id will break here, so in FS mode I add an extra bucket for device blocks. This bucket is explicitly not added in SE mode in order to not only avoid ugliness in the stats.txt file, but to avoid broken stats (some formulas break when a bucket is 0).
2010-02-23	stats: this makes some fixes to AverageStat and AverageVector.	Lisa Hsu
	Also, make Formulas work on AverageVector. First, Stat::Average (and thus Stats::AverageVector) was broken when coming out of a checkpoint and on resets, this fixes that. Formulas also didn't work with AverageVector, but added support for that.
2010-02-23	cache: pull CacheSet out of LRU so that other tags can use associative sets.	Lisa Hsu

2010-02-20	BaseDynInst: Preserve the faults returned from read and write.	Timothy M. Jones
	When implementing timing address translations instead of atomic, I forgot to preserve the faults that are returned from the read and write calls. This patch reinstates them.
2010-02-12	O3PCU: Split loads and stores that cross cache line boundaries.	Timothy M. Jones
	When each load or store is sent to the LSQ, we check whether it will cross a cache line boundary and, if so, split it in two. This creates two TLB translations and two memory requests. Care has to be taken if the first packet of a split load is sent but the second blocks the cache. Similarly, for a store, if the first packet cannot be sent, we must store the second one somewhere to retry later. This modifies the LSQSenderState class to record both packets in a split load or store. Finally, a new const variable, HasUnalignedMemAcc, is added to each ISA to indicate whether unaligned memory accesses are allowed. This is used throughout the changed code so that compiler can optimise away code dealing with split requests for ISAs that don't need them.
2010-02-12	BaseDynInst: Make the TLB translation timing instead of atomic.	Timothy M. Jones
	This initiates a timing translation and passes the read or write on to the processor before waiting for it to finish. Once the translation is finished, the instruction's state is updated via the 'finish' function. A new DataTranslation class is created to handle this. The idea is taken from the implementation of timing translations in TimingSimpleCPU by Gabe Black. This patch also separates out the timing translations from this CPU and uses the new DataTranslation class.
2010-02-12	Power ISA: Add an alignment fault to Power ISA and check alignment in TLB.	Timothy M. Jones

2010-02-10	ruby: fixed data block assignment fix	Brad Beckmann
	Fixed data block assignment to not delete if not internally allocated.
