2007-09-16mem: clean up bus/cache DPRINTFs a bitSteve Reinhardt
Not so much noise on failed sends, and more complete info when grepping a trace using an address. --HG-- extra : convert_revision : 05a8261c9452072ca08b906200c6322b33e2b9f1
2007-08-30params: Deprecate old-style constructors; update most SimObject constructors.Miles Kaufmann
SimObjects not yet updated: - Process and subclasses - BaseCPU and subclasses The SimObject(const std::string &name) constructor was removed. Subclasses that still rely on that behavior must call the parent initializer as : SimObject(makeParams(name)) --HG-- extra : convert_revision : d6faddde76e7c3361ebdbd0a7b372a40941c12ed

2007-07-29memory system: fix functional access bug.Steve Reinhardt
Make sure not to keep processing functional accesses after they've been responded to. Also use checkFunctional() return value instead of checking packet command field where possible, mostly just for consistency. --HG-- extra : convert_revision : 29fc76bc18731bd93a4ed05a281297827028ef75

2007-07-25Can't block on memInhibit packetsSteve Reinhardt
(now that bus no longer filters them for us). --HG-- extra : convert_revision : 34e7eaf5ee1e739f5557a2d417e569ed2ceb14b3
2007-07-23A couple more minor bug fixes for multilevel coherence.Steve Reinhardt
--HG-- extra : convert_revision : 370f9e34911157765be6fd49e826fa1af589b466
2007-07-23Major changes to how SimObjects are created and initialized. Almost allNathan Binkert
creation and initialization now happens in python. Parameter objects are generated and initialized by python. The .ini file is now solely for debugging purposes and is not used in construction of the objects in any way. --HG-- extra : convert_revision : 7e722873e417cb3d696f2e34c35ff488b7bff4ed
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
2007-07-17Forward cache-to-cache responses through other caches.Steve Reinhardt

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
2007-07-14Add CacheRepl trace flag and move a couple DPRINTFs to it.Steve Reinhardt

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

--HG-- extra : convert_revision : 626255a91679d534030c91bcdb4fc1bed36ceb9b
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

2007-06-25Get rid of requestCauses. Use timestamped queue to makeSteve Reinhardt
sure we don't re-request bus prematurely. Use callback to avoid calling sendRetry() recursively within recvTiming. --HG-- extra : convert_revision : a907a2781b4b00aa8eb1ea7147afc81d6b424140
