NAME

       x86info — display x86 CPU diagnostics

SYNOPSIS

       x86info  [-a]   [-c]   [-f]  [fB-F]   [-m] [-mhz]  [-r]  [?]  [--all]  [--cache] [--flags]
       [--verbose]  [--msr]  [--mhz]  [--registers]  [--help]

DESCRIPTION

       This manual page documents x86info, a program which displays a range of information  about
       the CPUs present in an x86 system.

       In  order  to  make  full  use  of this program you need to have the CPU ID and MSR device
       drivers  in  your   kernel   with   accessible   device   files   /dev/cpu/<n>/cpuid   and
       /dev/cpu/<n>/msr.

OPTIONS

       This  program  follows  the usual GNU command line syntax, with long options starting with
       two dashes (`-').  A summary of options is included below.

       ?           --help
                 Show summary of options.

       -a           --all
                 Show all information.  Equivalent to -c -f -m      -r -mhz.

       -c           --cache
                 Show TLB, cache sizes and cache associativity.

       -f           --flags
                 Show CPU feature flags.

       -m           --msr
                 Dump model specific registers.  This feature is currently only  supported  on  a
                 few  different  processors. Future versions will include parsing of bits in MSRs
                 for all processors.

       -mhz           --mhz
                 Estimate current clock rate.

       -mp            --mptable
                 Dump MP table showing CPUs BIOS knows about.

       -r           --registers
                 Show register values from all possible cpuid calls.

       -s           --show-machine-check
                 Show machine check exception information.

       -v           --verbose
                 Show verbose descriptions.
