2007-07-14Fix & tweak DPRINTFs for tracediff w/new cache code.Steve Reinhardt
Note that we should *not* print pointer values in DPRINTFs as these needlessly clutter tracediff output. --HG-- extra : convert_revision : 25a448f1b3ac8d453a717a104ad6dc0112fb30bb

2007-06-30Fix up a few statistics problems.Steve Reinhardt
Stats pretty much line up with old code, except: - bug in old code included L1 latency in L2 miss time, making it too high - UniCoherence did cache-to-cache transfers even from non-owner caches, so occasionally the icache would get a block from the dcache not the L2 - L2 can now receive ReadExReq from L1 since L1s have coherence --HG-- extra : convert_revision : 5052c1a1767b5a662f30a88f16012165a73b791c
