How can I integrate Garnet with the gem5 classic memory system?

[chitanda666]

hi,
I want to build a non-coherent cache system with the garnet network, but I find it that the ruby memory system must have a cache coherent protocol. I'm not sure if my understanding is correct.
Could you possibly provide guidance or an example on how to build a ruby system with non-coherent cache or using Garnet network with the classic memory system?
I would really appreciate any help in understanding this.
