msr-tools are utilities to access MSRs and CPU ID directly. Accessing any MSR or CPU ID with a simple console command is quite useful, especially when working on CPU related issues.

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

This project is released under GPL v2 or later.
