Hi Andreas,
Actually, I don't understand your note :
"you need to do this when the objects are first connected, not
retroactively in se.py"
Could you post a very simple and short example on using the CommMonitor ?
Hence, we can have a working starting point for this component. I think
it will be very useful for everyone.
Thank you very much.

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.
Andreas

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

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.
File "<string>", line 1, in <module>
File "/home/y11010s/gem5/src/python/m5/main.py", line 387, in main
exec filecode in scope

from CommMonitor import *

from MemObject import MemObject

from ClockedObject import ClockedObject
ImportError: No module named ClockedObject
Is there any examples to use communication monitor? Please give a advice.

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.

Subject: [gem5-users] How can I trace data of Cache?
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.
