MSR Definitions for Pentium Processors.
|
|
|
|
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.
