Individual bit fields

UINT32 MSR_GOLDMONT_SMM_FEATURE_CONTROL_REGISTER::Lock

[Bit 0] Lock (SMM-RWO) When set to '1' locks this register from further changes.

UINT32 MSR_GOLDMONT_SMM_FEATURE_CONTROL_REGISTER::Reserved1

UINT32 MSR_GOLDMONT_SMM_FEATURE_CONTROL_REGISTER::Reserved2

UINT32 MSR_GOLDMONT_SMM_FEATURE_CONTROL_REGISTER::Reserved3

UINT32 MSR_GOLDMONT_SMM_FEATURE_CONTROL_REGISTER::SMM_Code_Chk_En

[Bit 2] SMM_Code_Chk_En (SMM-RW) This control bit is available only if MSR_SMM_MCA_CAP[58] == 1. When set to '0' (default) none of the logical processors are prevented from executing SMM code outside the ranges defined by the SMRR. When set to '1' any logical processor in the package that attempts to execute SMM code not within the ranges defined by the SMRR will assert an unrecoverable MCE.

UINT32 MSR_GOLDMONT_SMM_FEATURE_CONTROL_REGISTER::Uint32

All bit fields as a 32-bit value

UINT64 MSR_GOLDMONT_SMM_FEATURE_CONTROL_REGISTER::Uint64

All bit fields as a 64-bit value
