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 op-
       tions 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.

		 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
