This is beneficial for testing purposes as there is no need to reflash the firmware just to toggle the lock bit. However, leaving the lock bit unset will break Windows' detection of VMX support and built-in virtualization features like Hyper-V. config SET_MSR_AESNI_LOCK_BIT bool "Lock the AES-NI enablement state" default y help This config sets the AES-NI lock bit, if available, to prevent any further change of AES-NI enablement. This may be disabled for e.g. testing or debugging. config CPU_INTEL_COMMON_TIMEBASE bool config CPU_INTEL_COMMON_RESERVED_PHYS_ADDR_BITS int help Specify the number of physical address reserved bits. This config can be set for SoCs with reserved bits which cannot be probed at runtime. A runtime detection by hardware probing will be attempted if the value is -1. endif config CPU_INTEL_COMMON_VOLTAGE bool config CPU_INTEL_COMMON_SMM bool default y if CPU_INTEL_COMMON
