Verlauf

Projektgeschichte und Nutzung

cpu_features is Google's portable C99 library for detecting CPU instruction-set and microarchitecture features at runtime.

Projektgeschichte

The official repository was created in 2018. Its README emphasizes portability, old-compiler compatibility, sandbox-aware detection strategies, thread safety, no allocation, no exceptions, unit tests, and suitability for low-level code such as libc-style routines.

Adoptionsgeschichte

The README positions cpu_features as cross-platform infrastructure across Linux, macOS, Windows, Android, and several CPU families. It also describes Android support and an NDK cpu-features.h compatibility layer, making it relevant to projects that need runtime dispatch without depending on platform-specific probes.

Wie es verwendet wird

Users include architecture-specific headers such as cpuinfo_x86.h or cpuinfo_arm.h, read feature structures returned by GetX86Info or GetArmInfo, and select optimized code paths based on runtime CPU support. The package also builds list_cpu_features for inspecting detected features, including JSON output.

Warum Paket-Nerds sich dafür interessieren

For packagers, cpu_features is a small but foundational library: it helps upstreams choose optimized code paths while still shipping generic binaries, and it is designed to build with CMake, Bazel, and Zig across many architectures.

Zeitleiste

  • 2018: The google/cpu_features repository was created.
  • 2025: v0.10.x releases were published from the official GitHub repository.
  • 2026: v0.11.0 was published from the official GitHub repository.

Related projects

  • The README describes cpu_features as an Android NDK cpu-features.h drop-in replacement.
