CoreFreq

CoreFreq is a low-level CPU monitoring and tuning tool for 64-bit processors. It is designed to retrieve processor data with a high degree of precision and expose details that are often hidden from simpler monitoring utilities. The project supports a wide range of processor families, including Intel, AMD, Arm A64, RISC-V RV64, and PowerPC64 little-endian systems. It provides BIOS-like visibility into CPU behavior, including frequencies, ratios, topology, temperatures, power, and performance counters. CoreFreq is useful for Linux users who need deep hardware insight for tuning, benchmarking, diagnostics, or overclocking research. Its main value is giving advanced users detailed processor telemetry through a specialized driver, daemon, and command-line interface.
