Description

Adds utilities for direct access to CPU Model-Specific Registers and CPUID information. Administrators, performance engineers, and hardware developers use them to inspect low-level processor behavior.

Use with care because MSR access is privileged and closely tied to hardware behavior. Reading is diagnostic, but writing incorrect values can destabilize or crash a system.

How to run

rdmsr

Commands: rdmsr
