I've already create the MemoryTrace object. How can I assign the object to the mem_trace parameter of the main memory?

I'm using v1.1 and I'd like to track the traffic of the main memory. I really don't know how to modify the config file. I attached my config file. Will you please create the object for me?

(Since we rewrote the memory system interface between those versions, the trace writer needs to be rewritten too, and no one has bothered.) If you're using v1.1, then you need to go into your config file and create either an M5Writer or ITXWriter object (see python/m5/objects/MemoryTrace.py) and assign it to the mem_trace parameter of the cache whose accesses you want to trace. It's not something you can enable purely via the command line. If you're using v2.0, then my suggestion is just to hack in some code to write out the address at the top of the handleAccess() method in src/mem/cache/cache_impl.hh. It's not that complex, and that way you can output whatever format you'd like. If you don't want to mess around with adding parameters to the cache to enable/disable tracing for particular caches (which is admittedly much more complex than it should be right now... we're working on simplifying that...), then you can just add some per-cache flags in cache.hh and set them based on the value of _name in the constructor (which is at the top of cache_impl.hh). Hope that helps...
