How To Install cpuinfo on Kali Linux

Introduction

In this tutorial we learn how to install cpuinfo on Kali Linux.

What is cpuinfo

cpuinfo is:

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)
