◆ 

struct { ... } MSR_IA32_DEBUG_INTERFACE_REGISTER::Bits

Individual bit fields

◆ DebugOccurred

UINT32 MSR_IA32_DEBUG_INTERFACE_REGISTER::DebugOccurred

[Bit 31] Debug Occurred (R/O): This "sticky bit" is set by hardware to indicate the status of bit 0. Default is 0. If CPUID.01H:ECX.[11] = 1.

Definition at line 5830 of file ArchitecturalMsr.h.

◆ Enable

UINT32 MSR_IA32_DEBUG_INTERFACE_REGISTER::Enable

[Bit 0] Enable (R/W) BIOS set 1 to enable Silicon debug features. Default is 0. If CPUID.01H:ECX.[11] = 1.

Definition at line 5818 of file ArchitecturalMsr.h.

◆ Lock

UINT32 MSR_IA32_DEBUG_INTERFACE_REGISTER::Lock

[Bit 30] Lock (R/W): If 1, locks any further change to the MSR. The lock bit is set automatically on the first SMI assertion even if not explicitly set by BIOS. Default is 0. If CPUID.01H:ECX.[11] = 1.
