%description
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
  * Vendor and microarchitecture for each CPU core
  * 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)
