IA32VMXPINBASEDCTLS
IA32_VMX_PINBASED_CTLS is a model-specific register used in Intel's Virtual Machine Extensions (VMX) to describe the allowed settings for pin-based VM-execution controls. The MSR is read by the hypervisor (or other VMX-enabled software) to determine which pin-based events can cause VM exits and how external pin events such as interrupts and NMIs are handled during virtualization. The address of this MSR is 0x481.
The MSR provides two 32-bit fields that encode masks for the pin-based controls. These masks, often referred
Pin-based VM-execution controls determine how certain external events are handled. Common examples include whether external interrupts
Understanding IA32_VMX_PINBASED_CTLS is essential for developers implementing or analyzing low-level VMX initialization, VM-entry validation, and the
