Hi all, When I switched gem5 from v21.0.0.0 to v21.1.0.1, the dumped `stats.txt` is much longer than previous one, filled with strange entry like the following.
==========stats.txt (Trimmed)========== system.cpu0.dcache.demandHits::cpu0.mmu.dtb.walker 730151 system.cpu0.dcache.demandHits::cpu0.mmu.itb.walker 730151 system.cpu0.dcache.demandHits::cpu0.inst 730151 system.cpu0.dcache.demandHits::cpu0.data 730151 system.cpu0.dcache.demandHits::cpu1.mmu.dtb.walker 730151 system.cpu0.dcache.demandHits::cpu1.mmu.itb.walker 730151 system.cpu0.dcache.demandHits::cpu1.inst 730151 system.cpu0.dcache.demandHits::cpu1.data 730151 system.cpu0.dcache.demandHits::cpu2.mmu.dtb.walker 730151 system.cpu0.dcache.demandHits::cpu2.mmu.itb.walker 730151 system.cpu0.dcache.demandHits::cpu2.inst 730151 system.cpu0.dcache.demandHits::cpu2.data 730151 system.cpu0.dcache.demandHits::cpu3.mmu.dtb.walker 730151 system.cpu0.dcache.demandHits::cpu3.mmu.itb.walker 730151 system.cpu0.dcache.demandHits::cpu3.inst 730151 system.cpu0.dcache.demandHits::cpu3.data 730151 system.cpu0.dcache.demandHits::total 13872869 ================================= It's strange that private Dcache in cpu0 generated stats related to other cores, and even with the identical numbers. I cannot find out how this happens. And the problem happens not only in cache stats. For TimingSimpleCPU, all `statExecutedInstType` seems to be covered by the same number. ==========stats.txt (Trimmed)========== system.cpu0.exec_context.thread_0.statExecutedInstType::No_OpClass 3988372 1.89% 1.89% # Class of executed instruction.

(Count) ================================= I tried to run `configs/example/se.py` with the same config for both v21.1 and v21.0 copy, but seems like the problem only happens in the newer one. Each copy is unmodified. Anyone have clue about this? I'm looking forward to your reply. :) Best regards, Meng
