cyring / CoreMod

Display system information of the Intel Core Processor, BIOS, and RAM memories

Purpose

Display system information of the Intel Core Processor, BIOS, and RAM memories

• Processor features (SMBios & CPUID)
• Core i7 frequency (MSR)
• Temperature for each Core (MSR)

• BIOS summary
• DDR3 timings (through memory controller I/O)
• Motherboard

• Base Clock frequency
• Processor socket and voltage
• Cache Memories

How to build CoreMod

Requirements

Mandatory :

• Linux x86_64 3.x or 4.x
• The GNU Compiler Collection: gcc - or - The C language family frontend for LLVM: clang
• Being root !
• Any Intel Core, i7, i5, i3 Processor

Optionally :

• The GNU Debugger: gdb and one graphical front-end for gdb: ddd
• The Intel 64 and IA-32 Architectures Software Developer’s Manual Volume 3
• The SMBIOS Reference Specification (C) Distributed Management Task Force

Compilation

Clone or download the source code then build the binary with make

$ make
Compiling : Done.
Linking   : Done.
Ready     : ./bin/coremod
Remark    : You must be root to run CoreMod

Debug

• Compile sources with the -g switch, or set it in the Makefile's CFLAGS
• Run the debugger GUI

# ddd ./bin/coremod

How to use CoreMod

Two kernel modules must be loaded with modprobe or insmod

• msr
• dmi-sysfs

then execute CoreMod as root

# ./coremod

press the menu key of the function you want to execute.
