/**
* \file libcpuid.h
* \author Veselin Georgiev
* \date Oct 2008
* \version 0.4.0
*
* Version history:
*
* * 0.1.0 (2008-10-15): initial adaptation from wxfractgui sources
* * 0.1.1 (2009-07-06): Added intel_fn11 fields to cpu_raw_data_t to handle
* new processor topology enumeration required on Core i7
* * 0.1.2 (2009-09-26): Added support for MSR reading through self-extracting
* kernel driver on Win32.
* * 0.1.3 (2010-04-20): Added support for greater more accurate CPU clock
* measurements with cpu_clock_by_ic()
* * 0.2.0 (2011-10-11): Support for AMD Bulldozer CPUs, 128-bit SSE unit size
* checking. A backwards-incompatible change, since the
* sizeof cpu_id_t is now different.
* * 0.2.1 (2012-05-26): Support for Ivy Bridge, and detecting the presence of
* the RdRand instruction.
* * 0.2.2 (2015-11-04): Support for newer processors up to Haswell and Vishera.
* Fix clock detection in cpu_clock_by_ic() for Bulldozer.
* More entries supported in cpu_msrinfo().
* *BSD and Solaris support (unofficial).
* * 0.3.0 (2016-07-09): Support for Skylake; MSR ops in FreeBSD; INFO_VOLTAGE
* for AMD CPUs. Level 4 cache support for Crystalwell
* (a backwards-incompatible change since the sizeof
* cpu_raw_data_t is now different).
* * 0.4.0 (2016-09-30): Better detection of AMD clock multiplier with msrinfo.
* Support for Intel SGX detection
* (a backwards-incompatible change since the sizeof
* cpu_raw_data_t and cpu_id_t is now different).

/** @mainpage A simple libcpuid introduction
*
* LibCPUID provides CPU identification and access to the CPUID and RDTSC
* instructions on the x86.
* <p>
* To execute CPUID, use \ref cpu_exec_cpuid <br>
* To execute RDTSC, use \ref cpu_rdtsc <br>
* To fetch the CPUID info needed for CPU identification, use
* \ref cpuid_get_raw_data <br>
* To make sense of that data (decode, extract features), use \ref cpu_identify <br>
* To detect the CPU speed, use either \ref cpu_clock, \ref cpu_clock_by_os,
* \ref cpu_tsc_mark + \ref cpu_tsc_unmark + \ref cpu_clock_by_mark,
* \ref cpu_clock_measure or \ref cpu_clock_by_ic.
* Read carefully for pros/cons of each method. <br>
*
* To read MSRs, use \ref cpu_msr_driver_open to get a handle, and then
* \ref cpu_rdmsr for querying abilities. Some MSR decoding is available on recent
* CPUs, and can be queried through \ref cpu_msrinfo; the various types of queries
* are described in \ref cpu_msrinfo_request_t.
* </p>
