       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.

       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.
