The record

Purpose: CoreFreq is CPU monitoring software with BIOS-like functionalities for 64-bit processors.
Monitoring: It retrieves CPU frequencies and ratios, performance counters, instructions per cycle, C-states, temperature, and documented core-voltage readings.
Topology: It displays processor features, brand and architecture strings, plus a topology map including caches.
Control features: The driver exposes controls for items including Turbo Boost, power management, thermal limits, prefetchers, and hardware-controlled performance states.
Interfaces: CoreFreq includes a daemon and a command-line client with monitoring views and JSON-encoded system information output.
Architecture support: The README lists Intel and AMD processor families, Arm A64, RISC-V RV64, and PowerPC64 LE as supported architectures.
Linux requirements: The README specifies a Linux kernel version 3.3 or newer and GNU C Library as dependencies.
Installation: The README documents building from source and distribution options including ArchLinux AUR, Gentoo, Debian, Ubuntu, TUXEDO, Fedora, AlmaLinux, and Rocky Linux.
Security boundary: The project says its kernel module uses shared memory to protect the kernel from the user-space part of the software.
Module signing: The README says users must sign the driver if kernel module signature verification is enabled.
Compatibility limit: The README cautions that some virtual machines do not provide access to registers used by the driver.
Terminal requirement: The README says the interface renders best in an ASCII console or an Xterm with VT100 support and notes that the display can stall in terminals narrower than 80 columns.
License: The repository identifies the software as GPL-2.0 licensed.
