cpuinfo

CPU INFOrmation library (binary utilities)

cpuinfo is a library to detect essential for performance optimization information about host CPU. Features - **Cross-platform** availability: - Linux, Windows, macOS, Android, and iOS operating systems - x86, x86-64, ARM, and ARM64 architectures - Modern **C/C++ interface** - Thread-safe - No memory allocation after initialization - No exceptions thrown - Detection of **supported instruction sets**, up to AVX512 (x86) and ARMv8.3 extensions - Detection of SoC and core information: - **Processor (SoC) name** - Integrated **GPU name** (Android/iOS only) - Vendor, **microarchitecture**, and ID (**MIDR** on ARM, **CPUID** leaf 1 EAX value on x86) for each CPU core - Detection of **cache information**: - Cache type (instruction/data/unified), size and line size - Cache associativity - Cores and logical processors (hyper-threads) sharing the cache - Detection of **topology information** (relative between logical processors, cores, and processor packages) - Well-tested **production-quality** code: - 60+ mock tests based on data from real devices - Includes work-arounds for common bugs in hardware and OS kernels - Supports systems with heterogenous cores, such as **big.LITTLE** and Max.Med.Min - Permissive **open-source** license (Simplified BSD) This package ships with several binary utilities.
