2008-08-11params: Convert the CPU objects to use the auto generated param structs.Nathan Binkert
A whole bunch of stuff has been converted to use the new params stuff, but the CPU wasn't one of them. While we're at it, make some things a bit more stylish. Most of the work was done by Gabe, I just cleaned stuff up a bit more at the end.
2008-08-03sockets: Add a function to disable all listening sockets.Nathan Binkert
When invoking several copies of m5 on the same machine at the same time, there can be a race for TCP ports for the terminal connections or remote gdb. Expose a function to disable those ports, and have the regression scripts disable them. There are some SimObjects that have no other function than to be used with ports (NativeTrace and EtherTap), so they will panic if the ports are disabled.

2008-07-01Remove delVirtPort() and make getVirtPort() only return cached version.Ali Saidi
2008-07-01Make the cached virtPort have a thread context so it can do everything that ↵Ali Saidi
a newly created one can.
2008-07-01After a checkpoint (and thus a stats reset), the ↵Ali Saidi
not_idle_fraction/notIdleFraction statistic is really wrong. The notIdleFraction statistic isn't updated when the statistics reset, probably because the cpu Status information was pulled into the atomic and timing cpus. This changeset pulls Status back into the BaseSimpleCPU object. Anyone care to comment on the odd naming of the Status instance? It shouldn't just be status because that is confusing with Port::Status, but _status seems a bit strage too.

--HG-- extra : convert_revision : d811bf87d1a0bfc712942ecd3db1b48fc75257af
2008-01-14The reason is that the event is supposed to put the instructions ready to ↵Ke Meng
execute for next cycle. And the FUCompletion event has a lower priority than CPU tick event. It is called after the iew->tick() for current cycle has already been executed and the issueToExecuteQueue has already advanced this time. And assume the issueToExecuteLatency is 1, to catch up, the increasement should be made at access(-1) instead of access(0). Otherwise I found it could increase the actual op_latency of the instructions to execute by 1 cycle and potentially put the simulated CPU into a permanent idle state.

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
