The README describes startup CPU detection cached for fast access during a Go program's lifetime, with support for x86/x64, ARM/ARM64, and RISC-V. ### 採用の歴史 cpuid fits Go module distribution as a library imported with github.com/klauspost/cpuid/v2, while also offering an installable cpuid binary via go install, GitHub release binaries, and Homebrew for macOS/Linux users. ### 使われ方 Go programs use the shared cpuid.CPU value to inspect brand, cores, cache, frequency, and feature sets, then call Supports, Has, or HasAll to gate optimized code paths. The command-line binary prints CPU details and supports JSON output. ### パッケージ好きにとっての重要性 For packagers and Go maintainers, cpuid is notable because it combines a Go module API with a packaged diagnostic binary, avoids external C code, and exposes runtime feature detection useful to compression, crypto, and other optimized Go libraries. ### タイムライン - 2015: The klauspost/cpuid repository was created. - 2024: v2.2.8 and v2.2.9 releases were published. - 2025: v2.2.10, v2.2.11, and v2.3.0 releases were published. ### Related projects - pkg.go.dev provides generated API documentation for the github.com/klauspost/cpuid/v2 Go module. ### ソース - - - - - ## セキュリティノート narrow executable package without higher-risk signals. - **Geiger リスク:** グリーン / 低 - narrow executable package without higher-risk signals ## ソースデータベース詳細 - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** cpuid - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## 他のパッケージマネージャ記録 - Debian apt - cpuid - 20250316-1: normalized package name match | Debian stable package indexes: cpuid from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | tool to dump x86 CPUID information about the CPU(s) | https://www.etallen.com/cpuid.html - Nix - cpuid: normalized package name match | nixpkgs package indexes: pkgs/by-name/cp/cpuid/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - Ubuntu apt - cpuid - 20240330-1ubuntu2: normalized package name match | Ubuntu 24.04 LTS package indexes: cpuid from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | tool to dump x86 CPUID information about the CPU(s) | https://www.etallen.com/cpuid.html - dnf - cpuid - 20250419-5.fc45: normalized package name match | Fedora Rawhide package metadata: cpuid from https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/repodata/210a2053c8e007daf9ae39c2a21daaed9b2ddd07d63ecffa597050361e73650c-primary.xml.zst | Dumps information about the CPU(s) | http://www.etallen.com/cpuid.html - zypper - cpuid - 20260503-1.3: normalized package name match | openSUSE Tumbleweed package metadata: cpuid from https://download.opensuse.org/tumbleweed/repo/oss/repodata/50b07339cb64c8ed4091bdbabddadc1ff5737b090e478818a195b40d8a3292861a879139b4a3987c31109699fde9fbf4a716367ddf4eef77da75f96e3193d6ed-primary.xml.zst | x86 CPU identification tool | http://etallen.com/cpuid.html - MacPorts - cpuid: normalized package name match | MacPorts ports tree: sysutils/cpuid/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## 関連リンク - [Source-control packages](https://pkg.so/ja/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://pkg.so/ja/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Language runtime packages](https://pkg.so/ja/language-runtime-packages/) - Matched language runtime, compiler, or interpreter metadata. - [Networking and protocol packages](https://pkg.so/ja/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [go](https://pkg.so/ja/brew/go/) - Build dependency declared by Homebrew. - [cpu_features](https://pkg.so/ja/brew/cpu-features/) - Shares pkgdb curated category or tags: cli, cpu, cpu-features, hardware-detection, library. - [zstd](https://pkg.so/ja/brew/zstd/) - Shares pkgdb curated category or tags: cli, library, system. - [keyutils](https://pkg.so/ja/brew/keyutils/) - Shares pkgdb curated category or tags: cli, library, system. - [libzip](https://pkg.so/ja/brew/libzip/) - Shares pkgdb curated category or tags: cli, library, system. - [hwloc](https://pkg.so/ja/brew/hwloc/) - Shares pkgdb curated category or tags: cli, library, system. - [wimlib](https://pkg.so/ja/brew/wimlib/) - Shares pkgdb curated category or tags: cli, library, system. - [stress-ng](https://pkg.so/ja/brew/stress-ng/) - Shares pkgdb curated category or tags: cli, cpu, system. - [mactop](https://pkg.so/ja/brew/mactop/) - Shares pkgdb curated category or tags: cli, go, system. - [libcpuid](https://pkg.so/ja/brew/libcpuid/) - Local package facts share a topical domain.
