## NAME
       /proc/cpuinfo - CPU and system architecture information

## DESCRIPTION
       _/proc/cpuinfo_
              This  is  a  collection  of CPU and system architecture dependent items, for each sup‐
              ported architecture a different list.  Two common entries are  _processor_  which  gives
              CPU  number  and _bogomips_; a system constant that is calculated during kernel initial‐
              ization.  SMP machines have information for each CPU.  The  [**lscpu**(1)](https://www.chedong.com/phpMan.php/man/lscpu/1/markdown)  command  gathers
              its information from this file.
