It wraps low-level CPUID and RDTSC access behind a portable API for Windows, Linux, and macOS. ### 项目历史 The official SourceForge project page describes LibCPUID as a small C library for x86 CPU detection and feature extraction, including vendor, model, brand string, code name, core counts, cache sizes, clock information, instruction-set checks, CPUID, and RDTSC. The Doxygen introduction records version 0.1.0 on 2008-10-15 as an initial adaptation from wxfractgui sources. Early releases added Intel Core i7 topology fields, Win32 MSR-reading support, improved CPU-clock measurement, AMD Bulldozer support, Ivy Bridge support, and RdRand detection. ### 采用历史 LibCPUID fits the distribution niche for programs that need CPU model and feature detection without carrying their own CPUID tables. It is packaged by Homebrew, Debian and Ubuntu as `cpuidtool`, Fedora-family distributions, Arch, Alpine, Nix, and openSUSE-derived systems. ### 使用方式 Developers link against libcpuid to ask whether a processor supports features such as SSE2, 3DNow!, RdRand, or vendor/model-specific capabilities. Users can also run the packaged `cpuid_tool` executable to inspect CPU information from the command line. ### 为什么软件包爱好者会关心 LibCPUID is a classic system-library package: tiny surface area, architecture-specific knowledge, and a constant need for updates as Intel and AMD ship new models. It is valuable because every downstream project does not need to parse raw CPUID leaves and maintain marketing names itself. ### 时间线 - 2008-10-15: 0.1.0 released as an adaptation from wxfractgui sources. - 2009-07-06: 0.1.1 added fields for Intel Core i7 topology enumeration. - 2009-09-26: 0.1.2 added Win32 MSR-reading support. - 2010-04-20: 0.1.3 improved CPU clock measurements. - 2011-10-11: 0.2.0 added AMD Bulldozer support and changed `cpu_id_t` size. -
