Member Data Documentation

◆ ANY

UINT32 MSR_IA32_PERFEVTSEL_REGISTER::ANY

[Bit 21] AnyThread: When set to 1, it enables counting the associated event conditions occurring across all logical processors sharing a processor core. When set to 0, the counter only increments the associated event conditions occurring in the logical processor which programmed the MSR.

Definition at line 1010 of file ArchitecturalMsr.h.

◆ 

struct { ... } MSR_IA32_PERFEVTSEL_REGISTER::Bits

Individual bit fields

◆ CMASK

UINT32 MSR_IA32_PERFEVTSEL_REGISTER::CMASK

[Bits 31:24] CMASK: When CMASK is not zero, the corresponding performance counter increments each cycle if the event count is greater than or equal to the CMASK.

Definition at line 1025 of file ArchitecturalMsr.h.

◆ E

UINT32 MSR_IA32_PERFEVTSEL_REGISTER::E

[Bit 18] Edge: Enables edge detection if set.

Definition at line 994 of file ArchitecturalMsr.h.

◆ EN

UINT32 MSR_IA32_PERFEVTSEL_REGISTER::EN

[Bit 22] EN: enables the corresponding performance counter to commence counting when this bit is set.

Definition at line 1015 of file ArchitecturalMsr.h.

◆ EventSelect

UINT32 MSR_IA32_PERFEVTSEL_REGISTER::EventSelect

[Bits 7:0] Event Select: Selects a performance event logic unit.

Definition at line 977 of file ArchitecturalMsr.h.

◆ INT

UINT32 MSR_IA32_PERFEVTSEL_REGISTER::INT

[Bit 20] INT: enables interrupt on counter overflow.

Definition at line 1002 of file ArchitecturalMsr.h.

◆ INV

UINT32 MSR_IA32_PERFEVTSEL_REGISTER::INV

[Bit 23] INV: invert the CMASK.

Definition at line 1019 of file ArchitecturalMsr.h.

◆ OS

UINT32 MSR_IA32_PERFEVTSEL_REGISTER::OS

[Bit 17] OS: Counts while in privilege level is ring 0.

Definition at line 990 of file ArchitecturalMsr.h.

◆ PC

UINT32 MSR_IA32_PERFEVTSEL_REGISTER::PC

[Bit 19] PC: enables pin control.

Definition at line 998 of file ArchitecturalMsr.h.

◆ Reserved

UINT32 MSR_IA32_PERFEVTSEL_REGISTER::Reserved

Definition at line 1026 of file ArchitecturalMsr.h.

◆ Uint32

UINT32 MSR_IA32_PERFEVTSEL_REGISTER::Uint32

All bit fields as a 32-bit value

Definition at line 1031 of file ArchitecturalMsr.h.

◆ Uint64

UINT64 MSR_IA32_PERFEVTSEL_REGISTER::Uint64

All bit fields as a 64-bit value

Definition at line 1035 of file ArchitecturalMsr.h.

◆ UMASK

UINT32 MSR_IA32_PERFEVTSEL_REGISTER::UMASK

[Bits 15:8] UMask: Qualifies the microarchitectural condition to detect on the selected event logic.

Definition at line 982 of file ArchitecturalMsr.h.

◆ USR

UINT32 MSR_IA32_PERFEVTSEL_REGISTER::USR

[Bit 16] USR: Counts while in privilege level is not ring 0.

Definition at line 986 of file ArchitecturalMsr.h.
