Hi Negin,
I have added some comments regarding CommMonitor use to the Wiki a while back:
http://www.m5sim.org/General_Memory_System#Tracing_and_traffic_generation
The command line you have included is using the debug flags to capture debug
output. The CommMonitor packet tracing is based on parameters belonging to the
monitor itself, and has nothing to do with the “--debug-file” and
“--debug-flags”. Are you also setting the correct tracing flags for the monitor
that you are instantiating. Perhaps you could copy in the snippet from the
CommMonitor section in your config.ini.
Thanks,
Andreas

Subject: [gem5-users] CommMonitor to capture cache traces
I’ve read these threads:
http://www.mail-archive.com/[email protected]/msg09221.html and
https://www.mail-archive.com/[email protected]/msg08511.html
I have successfully attached a CommMonitor between cpu and cache. The
CommMonitor appears in config.ini and the trace .ptrc file gets generated.
However, it contains only 1 packet.
Command line:
build/ARM/gem5.opt --debug-flags=CommMonitor --debug-file="trace-bbench.gz"
configs/example/fs.py --caches --l2cache --mem-size=256MB
--kernel=vmlinux.smp.mouse.arm --frame-capture --restore-with-cpu=timing
--num-cpus=1 --cpu-clock=2.0GHz -b bbench-ics --num-l2caches=1 --l1d_size=32kB
--l1d_assoc=8 --l1i_size=32kB --l1i_assoc=4 --l2_size=1MB --l2_assoc=8
Do I have to dumpstat regularly? Why is there only one packet captured even
though I am running bbench which supposedly generates a lot of cache events?
Thanks for your help
