Our oldest ones, buildhw-a64-01/02,07/08/09/10/11/12/13/21/22: These are lenovo emags. lscpu says: Vendor ID: APM BIOS Vendor ID: Ampere(TM) Model name: - BIOS Model name: eMAG CPU @ 3.0GHz cpufetch says: [WARNING]: SoC detection failed using /proc/cpuinfo: No string found [WARNING]: read_file: /sys/bus/nvmem/devices/rockchip-efuse0/nvmem: No such file or directory [WARNING]: read_file: /sys/bus/nvmem/devices/rockchip-otp0/nvmem: No such file or directory [WARNING]: guess_soc_from_uarch: No uarch matched the list [WARNING]: guess_soc_from_pci: No PCI device matched the list SoC: Unknown ##### ## # ##### ## #### ###### Technology: Unknown ### #### ### #### ### ### Microarchitecture: Xgene ### ## ### ### ## ### Max Frequency: 3.000 GHz ### #### ### ### ## ### Cores: 32 cores ###### ## ### ### ## ### Features: NEON,SHA1,SHA2,AES,CRC32 Peak Performance: 768.00 GFLOP/s No /proc/device-tree/compatible 2.
