How about getting rid of the L2 entirely and giving main memory the latency of an L2 hit? If I understand you correctly that would give you what you're looking for.

Hi All,
I want to simulate a system in which I have only L1 cache latency,i.e., if I have a miss in the L1 cache and the data is fetched from L2 cache or from memory still I want to observe just the L1 cache latency. Can I make the latency of L2 cache/memory to be 0 to achieve this? Or is there any parameter in M5 configuration, like max load latency or something, which I can set so as to fulfill my objective.

Thanks,
Prabhat
