2008-11-10Cache: Refactor packet forwarding a bit.Steve Reinhardt
Makes adding write-through operations easier.
2008-11-04decouple eviction from insertion in the cache.Lisa Hsu
2008-11-04Change the findBlock(addr, lat) to accessBlock, which I think has better ↵Lisa Hsu
connotations for what is really happening and how it should be used.
2008-11-04get rid of all instances of readTid() and getThreadNum(). Unify and eliminateLisa Hsu
redundancies with threadId() as their replacement.
2008-10-09eventq: convert all usage of events to use the new API.Nathan Binkert
For now, there is still a single global event queue, but this is necessary for making the steps towards a parallelized m5.
2008-06-28Backed out changeset 94a7bb476fca: caused memory leak.Steve Reinhardt
2008-06-21Generate more useful error messages for unconnected ports.Steve Reinhardt
Force all non-default ports to provide a name and an owner in the constructor.
2008-06-13Get rid of bogus cache assertion.Steve Reinhardt
I was asserting that the only reason you would defer targets is if a write came in while you had an outstanding read miss, but there's another case where you could get a read access after you've snooped an invalidation and buffered it because it applies to a prior outstanding miss.

2008-01-02Add ReadRespWithInvalidate to handle multi-level coherence situationSteve Reinhardt
where we defer a response to a read from a far-away cache A, then later defer a ReadExcl from a cache B on the same bus as us. We'll assert MemInhibit in both cases, but in the latter case MemInhibit will keep the invalidation from reaching cache A. This special response tells cache A that it gets the block to satisfy its read, but must immediately invalidate it. --HG-- extra : convert_revision : f85c8b47bb30232da37ac861b50a6539dc81161b

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

2007-07-22Replace 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

2007-07-21Deal 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

2007-06-30Fix 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
