The reason you are probably not getting traffic information is because you are probably printing out the traffic in the bus object. In the case of the cpu->L1 interface we use a specialized interface that is not a bus object (hence the in_bus=null). If you turn on trace flags by doing --root.trace.flags="Bus Cache" you should see all the traffic entering the L1. If you have added some code to the Bus object trying to print out the traffic you will also need to add some printouts in the specialized interface to the L1 (m5/mem/memory_interface_impl.hh). You probably want to add your printout in the access function.

Hi all
In the m5 stats file we are not able to get the traffic from CPU to L1..
We have the traffic from L1->L2,L2->L3 and from L3->memory..
Please tell me what would be the reason for this ?

Ur help will be highly appreciated..

Thank you
