2010-08-23MEM: Make CLREX a first class request operation and clear locks in caches ↵Gene Wu

2010-02-24cache 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.
2010-02-23cache: 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).
2010-02-23cache: pull CacheSet out of LRU so that other tags can use associative sets.Lisa Hsu
2010-01-12cache: make tags->insertBlock() and tags->accessBlock() context aware so ↵Lisa Hsu
that the cache can make context-specific decisions within their various tag policy implementations.
