The cpu info command displays CPU (processor) information using the CPUID instruction. If the requested information is displayed for the respective logical processor, it means that the processor is in a working state. This command is differentiated from System Inventory or System Info where processor information is coming from SMBIOS. This command executes the x86 CPUID instructions to collect and display respective CPU type, family, mode, stepping, and strings. Boot strap processor (BSP) CPU information is displayed without options.
