The msrtool utility can dump MSR (model-specific register) contents, which is useful for debugging and development.

The tool currently supports the following CPUs/chipsets:

- Intel Pentium III
- Intel Pentium IIV
- Intel Core
- Intel Core 2
- Intel Nehalem
- Intel Atom
- AMD Geode GX2
- AMD Geode LX
- AMD Geode CS5536
- AMD K8
It has been developed for the coreboot project (see http://coreboot.org for details on coreboot), but may also be useful for other purposes.
