2007-07-25Can't block on memInhibit packetsSteve Reinhardt

2007-07-24Don't delete request at target... requester still needs it.Steve Reinhardt
--HG-- extra : convert_revision : 76377ca2e4d7ea70d1d54d325a63ce710e260b93
2007-07-23A couple more minor bug fixes for multilevel coherence.Steve Reinhardt
--HG-- extra : convert_revision : 370f9e34911157765be6fd49e826fa1af589b466
2007-07-22Replace lowerMSHRPending flag with more robust schemeSteve Reinhardt
based on following Packet senderState links. --HG-- extra : convert_revision : 9027d59bd7242aa0e4275bf94d8b1fb27bd59d79
2007-07-22Replace DeferredSnoop flag with LowerMSHRPending flag.Steve Reinhardt
Turns out DeferredSnoop isn't quite the right bit of info we needed... see new comment in cache_impl.hh. --HG-- extra : convert_revision : a38de8c1677a37acafb743b7074ef88b21d3b7be
2007-07-22A few minor non-debug compilation issues.Steve Reinhardt
--HG-- extra : convert_revision : d59a5cad6187a2229dddd1a48282ebd2923d1d8d
2007-07-21Deal with invalidations intersecting outstanding upgrades.Steve Reinhardt
If the invalidation beats the upgrade at a lower level then the upgrade must be converted to a read exclusive "in the field". Restructure target list & deferred target list to factor out some common code. --HG-- extra : convert_revision : 7bab4482dd6c48efdb619610f0d3778c60ff777a
2007-07-21Several more fixes for multi-level timing coherence.Steve Reinhardt
- Add "deferred snoop" flag to Packet so upper-level caches can distinguish whether lower-level cache request was in-service or not at the time of the original snoop. - Revamp response handling to properly handle deferred snoops on non-cache-fill requests (i.e. upgrades). - Make sure forwarded writebacks are kept in write buffer at lower-level caches so they get snooped properly. --HG-- extra : convert_revision : 17f8a3772a1ae31a16991a53f8225ddf54d31fc9
2007-07-17Make sure responses never get blocked.Steve Reinhardt

--HG-- extra : convert_revision : 08091670fc319876012ed139fcd2584c364a980c
2007-07-15Fix up a bunch of multilevel coherence issues.Steve Reinhardt
Atomic mode seems to work. Timing is closer but not there yet. --HG-- extra : convert_revision : 0dea5c3d4b973d009e9d4a4c21b9cad15961d56f
2007-07-15Make Bus::findPort() a little more useful.Steve Reinhardt
Move check for loops outside, since half the call sites end up working around it anyway. Return integer port ID instead of port object pointer. --HG-- extra : convert_revision : 4c31fe9930f4d1aa4919e764efb7c50d43792ea3
2007-07-14Add CacheRepl trace flag and move a couple DPRINTFs to it.Steve Reinhardt

--HG-- extra : convert_revision : f99a33b2df6a6c5592856d17d00e73ee83267442
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
2007-07-03Delete packets when we're done with them.Steve Reinhardt

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
2007-06-30Get rid of Packet result field. Error responses areSteve Reinhardt

src/cpu/memtest/memtest.cc: Need to set packet source field so that response from cache doesn't run into assertion failure when copying source to dest. src/mem/packet.hh: Copy source field when copying packets. Assert that source is valid before copying it to dest when turning packets around. --HG-- extra : convert_revision : 09e3cfda424aa89fe170e21e955b295746832bf8
2007-06-22Fixes to hitLatency, blocking, buffer allocation.Steve Reinhardt
