Hi all, The issue has nothing to do with the CommMonitor.
You do not have to add any "addToPath" or imports. Instead, in CacheConfig, simply instantiate a CommMonitor and connect it as you already describe. Note that you need to do this when the objects are first connected, not retroactively in se.py. Moreover, to get an actual trace, use the "trace file" parameter of the CommMonitor to dump an protobuf endoded trace of packets. The debug flags and the deceiving "trace-file" gem5 command-line parameter will simply pipe the debug output to a text file. This is not what you want (I suspect). Good luck.

Hi everybody, I have the same error as Heungsun's one when using the CommMonitor. Someone would know how do we resolve it, please ? Thank you very much Sophiane Le 15/10/2013 10:48, 윤흥선 a écrit : Andreas, Thanks for your answer . I tried to use CommMonitor. but I've got errors. I modified se.py as follow. ... addToPath('../../src/mem') ... from CommMonitor import * ... root = Root(full_system = False, system = system) #Commonitor system.cachemonitor = CommMonitor() system.tol2bus.master = system.cachemonitor.slave system.cachemonitor.master = system.system.membus.slave Simulation.run(options, root, system, FutureClass) and my command line is ./build/ARM/gem5.opt --debug-flags=CommMonitor --trace-file=comm_trace.out configs/example/se_cache_monitor.py -c queens -o 4 --cpu-type=arm_detailed --num-cpus=4 --caches --l2cache --l2_assoc=2 and I got messages.

If you're looking for a packet trace, you can always use the CommMonitor. You can even put one on either side of the cache if desired. You need to edit the scripts to connect it though. The trace is encoded (for space and performance reasons), but you can view it using the utility scripts in the util dir.

Hi all, I'm newbie of gem5. I'd like to trace data of cache. how can I get data of cache? in Cache_impl.hh, should I add a new flag? Could you explain what should I code in Cache_impl.hh? ex) DPRINTF(Cache, "address %x : data %h",pkt->getAddr(),??); thanks in advance. -- IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.
