MSR Definitions for Intel processors based on the Broadwell microarchitecture.
Provides defines for Machine Specific Registers(MSR) indexes. Data structures
are provided for MSRs that contain one or more bit fields. If the MSR value
returned is a single 32-bit or 64-bit value, then a data structure is not
provided for that MSR.
