◆ Valid

UINT32 MSR_IA32_SMM_MONITOR_CTL_REGISTER::Valid

[Bit 0] Valid (R/W). The STM may be invoked using VMCALL only if this bit is 1. Because VMCALL is used to activate the dual-monitor treatment (see Section 34.15.6), the dual-monitor treatment cannot be activated if the bit is 0. This bit is cleared when the logical processor is reset.
