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  accessable  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	    --cacheinfo
		 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-bluesmoke
		 Show machine check exception information.

       -v	    --verbose
		 Show verbose descriptions.
