The first entry, /sys/firmware/dmi/entries/4-0/raw, is only used, so lscpu will show the same information of the SMBIOS type4 from the entry even if the system has two diffrent cpu models, like Cortex-A53 and Cortex-A72. I'm not familiar with the heterogenous SoC, probably each CPU model has own SMBIOS type4, right? for example, /sys/firmware/dmi/entries/4-0/raw is for Cortex-A53 and /sys/firmware/dmi/entries/4-1/raw is for Cortex-A72. > > Maybe we should disable reading from BIOS on systems with more than > one CPU type. I agree with you. Thanks, Masa
