CPU brand not show in /proc/cpuinfo for Cavium ThunderX2 ARMv8
Posted: 2019/05/26 07:03:11
I'm running CentOS Linux release 7.6.1810 (AltArch) on a machine with Cavium ThunderX2 CPU.
This is ARMv8 architecture, arch reports it as aarch64
cat /proc/cpuinfo reports it as (showing only the last core)
Any information about branding is missing. This creates a problem because some software packages rely on proc/cpuinfo to get system specs.
lscpu also does not show brand:
dmidecode, however, shows CPU brand, but this requires sudo rights.
can it be fixed somehow?
