Hello Gabriel Have tried to follow your flow. Have generated the custom version of CHI.py and se.py (both files attached).
I have used HelloWorld program to pipe flush. The command I have used to run being: ./build/ARM/gem5.opt configs/example/se_kirin_custom.py --ruby --topology=Pt2Pt --cpu-type=DerivO3CPU --num-cpus=4 --num-dirs=1 --num-l3caches=1 --num-cpu-bigclust=1 --num-cpu-littleclust=3 --num-clusters=2 --cpu-type-bigclust=DerivO3CPU --cpu-type-littleclust=DerivO3CPU --cmd=tests/test-progs/hello/bin/arm/linux/hello 1. The Ruby memory system seems to have been generated with the two clusters (bigCluster and littleCluster) (checking m5out/config.ini) [system.ruby] type=RubySystem children=bigCluster clk_domain hnf littleCluster network power_state snf access_backing_store=false all_instructions=false block_size_bytes=64 clk_domain=system.ruby.clk_domain eventq_index=0 hot_lines=false memory_size_bits=48 num_of_sequencers=2 number_of_virtual_networks=4 phys_mem=Null power_model= power_state=system.ruby.power_state randomization=false system=system 2. However, I am getting the following run time errors: warn: sys_port_proxy.slave is deprecated. `slave` is now called `in_ports` warn: cntrl.memory is deprecated. The request port for Ruby memory output to the main memory is now called `memory_out_port` Global frequency set at 1000000000000 ticks per second warn: system.ruby.network.ext_links0.ext_node adopting orphan SimObject param 'sequencer' warn: system.ruby.network.ext_links1.ext_node adopting orphan SimObject param 'sequencer' ['dot', '-Tsvg', '/tmp/tmp6kqukhxa'] return code: 1 stdout, stderr: b'' b'Error: /tmp/tmp6kqukhxa: syntax error in line 5993 scanning a quoted string (missing endquote? longer than 16384?)\nString starting:"adaptive_routing=false \\buffer_size=4 \\clk_domain=system.rub\n' <== Not sure which file the syntax error is occurring warn: failed to generate dot output from m5out/config.dot warn: DRAM device capacity (8192 Mbytes) does not match the address range assigned (512 Mbytes) fatal: system.cpu0.l1d.data_channel_size without default or user set value Any pointers as to where I should look to resolve the errors?

However, I didn't get that you need private L2s. But if you call the big and little clusters by the term "cluster", then I believe that each cluster has a single entry point to the coherent interconnect which usually is the master port of a shared cache. In that case, the CHI RN-F is what maps to such concept of CPU cluster. I would recommend starting with private L1s and shared L2 until things work, as this is natively supported by the CHI config files. Then, hack your way through the CHI config files to make the L2 private and add a shared L3 if needed. You will have to modify CHI_config.CHI_RNF. 3- create_system in CHI.py expects system to be populated with CPUs (system.cpu). The only thing that differs between a CPU type and another really is its accuracy : atomic, minor, O3, etc. The performance of the simulated CPU then depends on the specific parameters of that CPU but you can look at that later. Having said that, I would write something like: assert(len(system.cpu) == options.num_cpus_little + options.num_cpus.big) ruby_system.little_cluster = CHI_RNF(system.cpu[:options.num_cpus_little], <other parameters>) ruby_system.big_cluster = CHI_RNF(system.cpu[-options.num_cpus_big:], <other parameters>) ruby_system.little_cluster.addPrivL2Cache(...) ruby_system.big_cluster.addPrivL2Cache(...)
