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.
