[gem5-users] How to trace the communications between multi-core system caches and memory?

[Haoran Wang]

Hello guys,
If i want to trace the communications between multi-core system components,
like first core's L1cache send a packet to first core's L2cache.
If I want to trace such informations, how would I achieve this? Any suggestions?

Thanks for your help.

[Andreas Brokalakis]

Hi Biruk,

yes you can do that. You may use the GUI just for the overall initial setup
and then you can edit the cGEM5 paameters to your will (go to
~/COSSIM/gem5/run.sh script that is produced by the GUI and enter the exact
configuration that you want).

Best,
Andreas
