## 项目历史与用法

cpuid is a Go package and command-line tool for detecting CPU information and CPU feature flags at runtime without cgo.

### 项目历史

The official GitHub repository was created in 2015. 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.

### 采用历史

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.

### 使用方式

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.

### 为什么软件包爱好者会关心

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.

### 时间线

- 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.
