x86info — display x86 CPU diagnostics

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.
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.
