             /*
              * If there are external interrupts pending but masked by the TPR value, apply the threshold so that if the guest
              * lowers the TPR, it would cause a VM-exit and we can deliver the interrupt.
+             * If there are external interrupts pending but masked by the TPR value, instruct VT-x to cause a VM-exit when
+             * the guest lowers its TPR below the highest-priority pending interrupt and we can deliver the interrupt.
              * If there are no external interrupts pending, set threshold to 0 to not cause a VM-exit. We will eventually deliver
              * the interrupt when we VM-exit for other reasons.
