Thanks a lot for your help!

I think I must missed something since I looked at baseCPU.py, the
addTwoLevelCacheHierarchy seems to just add L1 and L2, but not L3. Could you
elaborate more?


def addTwoLevelCacheHierarchy(self, ic, dc, l2c):
        self.addPrivateSplitL1Caches(ic, dc)
        self.toL2Bus = Bus()
        self.connectMemPorts(self.toL2Bus)
        self.l2cache = l2c
        self.l2cache.cpu_side = self.toL2Bus.port
        self._mem_ports = ['l2cache.mem_side']

Thanks!
