CPUID(8)                                                 CPUID(8)

          cpuid, icanhasvmx - print processor information

          aux/cpuid [ -ar ]

          aux/icanhasvmx [ -r ]

          Intel and compatible processors since the Pentiumâ„¢ (or late
          486) provide the CPUID instruction that returns information
          about the chip. The cpuid program enumerates and prints this
          information in a simple textual format. The output consists
          of multiple lines prefixed with a keyword describing the
          information that follows.

          With the -r option, the format changes to raw hexadecimal
          output with the keyword being the AX input register to the
          CPUID instruction followed by 4 colums with the output reg-
          isters AX, BX, CX and DX.

          The -a option prints enumerated items in raw format if no
          keyword is known instead of omitting it (default).

          The keywords supported so far are:

               Processor vendor string

          procmodel, extmodel
               Processor model, hexadecimal model / family id

          features, extfeatures
               Feature bits, a variable list of feature acronyms

               Processor name string

          physbits, virtbits, guestbits
               Address lines, decimal in bits

          Icanhasvmx queries the virtual machine extension (VMX) capa-
          bilities.  If -r is specified, it prints the results in raw
          hexadecimal; otherwise it produces a human-readable format.
          In any case it prints a summary on fd 2.
