I have my dedicated controller module that have L1Icache as member function (I want to interfere with all incoming and outgoing request and response from cache and may modify based on some algorithm) with similler parameter and port structure. In PrivateL1SharedL2CacheHierarchy cache hierarchy, I wanted to change the L1Cache with This Controller module. When I run my configuration, I encountered this error: Error in unproxying param 'assoc' of board.cache_hierarchy.l1icaches0.tags AttributeError: Can't resolve proxy 'assoc' of type 'Int' from 'board.cache_hierarchy.l1icaches0.tags' Anyone have any idea how I could solve this? Note: To me it seems like, gem5 trying to create the structure of the system where the board trying to find the l1icaches0 directory and trying to get tag value from there. I could not find where it was happening. Also, I have found some questions where others faced the same type of error ( not exactly the same error) and creating a subsystem may resolve it. But I could not find any resources on how this subsystem structure works in gem5 and how to make your own subsystem. Any known resources on that? Best Shaikhul

Hi Shaikhul, I think that you have somehow unset the `assoc` parameter (or set it to None) in the cache. Can you provide us the exact script you're running, the command line that you use to run, the information about the gem5 build (variant used), the version of gem5 you're using, and any modifications you have made to gem5?

isa_required=ISA.X86,

 kvm_required=True,

         L1PrivateCtrl(
             icache_size=self._l1i_size,
             icache_assoc=self._l1i_assoc,
             icache_writeback_clean=False,
         )
         for i in range(board.get_processor().get_num_cores())
     ]

Right now my controller object just intended to work as wrapper for icache ( when I could ensure that I could take request from cpu and send it to icache and vice versa, I'll start working on my main target). my simple script: > ## import librarie ######### Parameters ########## > > #Memory > L1Cache = "32KiB" # same size data and instruction cache > Asso_L1 = 4 # associativity > Asso_L2 = 8 > L2Cache = "256KiB" # 8 times of L1 > L3Cache = "4096KiB" #16 times of L2 > DRAM_size = "2GiB" > ## config for interconnect netowrk > number_of_cpu = 2 > ClkFreq = "3GHz" > isa=ISA.X86 > > ################################## requires( > isa_required=ISA.X86, > kvm_required=True, > ) > > cache_hierarchy = > PrivateL1SharedL2CacheHierarchy(l1d_size=L1Cache,l1i_size=L1Cache,l2_size=L2Cache,l1d_assoc=Asso_L1,l1i_assoc=Asso_L1,l2_assoc=Asso_L2) > memory = SingleChannelDDR3_1600(DRAM_size) > processor = SimpleProcessor( cpu_type=CPUTypes.O3, > num_cores=number_of_cpu,isa=isa) > board = SimpleBoard(clk_freq=ClkFreq, processor=processor, memory=memory, > cache_hierarchy=cache_hierarchy) > #simulation setup > binary = BinaryResource('/path/to/binary') > board.set_se_binary_workload(binary) > #simulation start > simulator = Simulator(board=board) > simulator.run() In PrivateL1SharedL2CacheHierarchy(), I changed L1ICache with L1PrivateCtrl() which takes same argument as l1icache self.l1icaches = [ > L1PrivateCtrl( > icache_size=self._l1i_size, > icache_assoc=self._l1i_assoc, > icache_writeback_clean=False, > ) > for i in range(board.get_processor().get_num_cores()) > ] My L1PrivateCtrl is a library for my L1PrivateController simobject which has CacheParams icache_param as a local variable. For now, it just takes parameters for cache, assigns them in icache_param manually and instantiates cache objects with icache_param argument. Right now, I'm just trying to implement my controller object to work as an intermediary between cpu and icache.
