The Value of the Model-Specific Register (MSR) Tools Project
MSR Tools project provides utilities to access the processor MSRs and CPU ID directly.
This project is composed of three different user space console applications.
- rdmsr – read MSR from any CPU or all CPUs
- wrmsr – write values to MSR on any CPU or all CPUs
- cpuid – show identification and feature information of any CPU
Who It’s For
This project is for system developers, testers, debuggers, and other contributors creating or customizing any device based on IA processor.
This is a small open source project distributed under the GPL v2 open source license. With a mature and established codebase containing about 700 lines of code begun in 2000 on zytor.com, it is now housed on 01.org. MSR Tools is written only in C.
About Intel Involvement
Intel is a major contributor to MSR Tools, enabling the ecosystem to customize and differentiate their products. This project is optimized through open source to for the Intel® Atom™ processors, Intel® Core™ processors, and any future Intel processors supporting MSR and CPUID.
