2008-09-10style: Remove non-leading tabs everywhere they shouldn't be. Developers ↵Ali Saidi

2008-07-15Add missing newlines to Bus DPRINTFs.Steve Reinhardt
2008-07-01Remove delVirtPort() and make getVirtPort() only return cached version.Ali Saidi
2008-07-01Change everything to use the cached virtPort rather than created their own ↵Ali Saidi
each time. This appears to work, but I don't want to commit it until it gets tested a lot more. I haven't deleted the functionality in this patch that will come later, but one question is how to enforce encourage objects that call getVirtPort() to not cache the virtual port since if the CPU changes out from under them it will be worse than useless. Perhaps a null function like delVirtPort() is still useful in that case.

2008-06-14MemReq: Add option to reset the time on a request.Nathan Binkert
2008-06-13Get rid of bogus bus assertion.Steve Reinhardt
It runs out that if a MemObject turns around and does a send in its receive callback, and there are other sends already scheduled, then it could observe a state where it's not at the head of the list but the bus's sendEvent is not scheduled (because we're still in the middle of processing the prior sendEvent).
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
