A model-specific register (MSR) is any of various control registers in the x86 system architecture used for debugging, program execution tracing

2024/2/23 -Model-specific registers (MSR) are control registers provided by the processor implementation so that system software can interact with a ...

MSRs are 64-bit wide. The presence of MSRs on your processor is indicated by CPUID.01h:EDX[bit 5]. const ...

2023/6/6 -Those registers are located inside each CPU core (each core has its own set). They are not necessarily all in one place - they can be sprinkled around the core.

2023/8/8 -Enumeration of architectural model specific registers (MSRs) on Intel® processors used to help mitigate transient execution attacks.

This application is a pair of services to automate the application of CPU performance and power saving functionality, based on a variety of triggers.

The way the MSR is read is processor specific. If you want to run # this on AMD or other CPU types, the MSR definitions section will need editing.

In this paper, we show that MSRs and their configuration bits can be detected automatically on Intel and AMD CPUs. We introduce MSRevelio, a framework to ...

/dev/cpu/CPUNUM/msr provides an interface to read and write the model-specific registers (MSRs) of an x86 CPU.
