Hi, All, Would you mind to share the details about using the NoncoherentCache. I have the same issue about "panic: panic condition !from_cpu_side occurred: Non-coherent cache received functional snoop request" when I use the NoncoherentCache as the last level cache(L3 cache). I defined the L3 cache as an instance of NoncoherentCache, and define the L3Bus similar to L2Xbar. But I suffered the previous error and can not resolve it. Instead, I use Cache for L3 and make my code work. But I am still wondering how you get rid of this error.
Best regards.
