       x86info -- display x86 CPU diagnostics

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

       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 driv-
       ers 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.
