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.
Show summary of options.
Show all information. Equivalent to -c -f -m -r -mhz.
Show TLB, cache sizes and cache associativity.
Show CPU feature flags.
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.
Estimate current clock rate.
Dump MP table showing CPUs BIOS knows about.
Show register values from all possible cpuid calls.
Show machine check exception information.
Show verbose descriptions.
