cpudetect - Modern CPU Feature Detection Library

A clean, modular Rust library for comprehensive x86_64 CPU feature detection with a beautiful command-line interface.

Building

Library (static and dynamic)

cargo build --release --lib

This produces:

• libcpudetect.rlib (Rust static library)
• libcpudetect.so (dynamic library on Linux)
• libcpudetect.a (C-compatible static library)

Frontend Binary

cargo build --release --bin lscpu

All

cargo build --release

Features

🎯 Comprehensive Feature Detection (200+ features)

• ✅ SIMD Extensions: SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AVX, AVX2, AVX-512 (all variants), AMX
• ✅ Cryptography: AES-NI, SHA, PCLMULQDQ, GFNI, VAES, VPCLMULQDQ
• ✅ Security:
  • Speculation control (IBRS, IBPB, STIBP, SSBD)
  • Memory protection (SMEP, SMAP, PKU, PKS, CET, UMIP)
  • Security extensions (SGX, TME, Key Locker)
  • Vulnerability mitigations (L1D_FLUSH, MD_CLEAR, etc.)
• ✅ Virtualization: VMX (Intel VT-x), SVM (AMD-V), hypervisor detection
• ✅ Performance: BMI1/2, ADX, POPCNT, ERMS, FSRM, FMA, hardware prefetchers
• ✅ Memory Management: 5-level paging (LA57), 1GB pages, PCID, INVPCID
• ✅ Modern Extensions:
  • Intel: AMX, AVX-512 FP16, UINTR, SERIALIZE, WAITPKG, ENQCMD
  • AMD: CLZERO, WBNOINVD, SSE4a, XOP, FMA4, TBM
• ✅ Debug & Power: Intel PT, Architectural LBR, HWP, MONITOR/MWAIT
• ✅ Hybrid Architecture: P-core/E-core detection (Intel 12th gen+)

🎨 Beautiful Command-Line Interface

• Color-coded output by feature category
• Clean, organized presentation
• Unicode box drawing characters
• Feature grouping (SIMD, Cryptography, Security, etc.)

🏗️ Clean Architecture

• Modular design following Unix philosophy
• Each module does one thing well`
• Zero-cost abstractions
• Minimal dependencies
