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. ### Adoptionsgeschichte 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. ### Wie es verwendet wird 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. ### Warum Paket-Nerds sich dafür interessieren 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. ### Zeitleiste - 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. ### Quellen - - - - - ## Sicherheitshinweise narrow executable package without higher-risk signals. - **Geiger-Risiko:** grün / niedrig - narrow executable package without higher-risk signals ## Andere Paketmanager-Einträge - 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/07190dc5ae9f35ae73866675fed6d95fe6e8d9fe22c9d7cdf85862cb2ed24a4c-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 ## Combined YAML source View the package source record on GitHub.
