Individual bit fields

COS

UINT32 MSR_IA32_PQR_ASSOC_REGISTER::COS

[Bits 63:32] COS (R/W). The class of service (COS) to enforce (on writes); returns the current COS when read. If ( CPUID.(EAX=07H, ECX=0):EBX.[15] = 1 ).

Definition at line 6083 of file ArchitecturalMsr.h.

ResourceMonitoringID

UINT32 MSR_IA32_PQR_ASSOC_REGISTER::ResourceMonitoringID

[Bits 31:0] Resource Monitoring ID (R/W): ID for monitoring hardware to track internal operation, e.g. memory access. N = Ceil (Log:sub:2 ( CPUID.(EAX= 0FH, ECX=0H).EBX[31:0] +1)).
