[edk2] [PATCH 04/11] UefiCpuPkg/Msr: Add CPUID signature check MACROs
Posted by Jeff Fan 7 years, 7 months ago 
All model-specific MSRs are related to processor signatures that are defined in
each section in Chapter 35 Model-Specific-Registers (MSR), Intel(R) 64 and
IA-32 Architectures Software Developer's Manual, Volume 3, September 2016.
