 This MSR keeps a running count of the energy used in a specified domain in microJoules. This metric provider specifically reads from the `energy-pkg` domain, which gives you the cumulatove energy used by the domains `energy-cores`, `energy-gpu` and some extra parts like the voltage regulator and such that also reside on the package.
