Abstract: One embodiment of the present invention is a technique to invalidate entries in a translation lookaside buffer (TLB). A TLB in a processor has a plurality of TLB entries. Each TLB entry is associated with a virtual machine extension (VMX) tag word indicating if the associated TLB entry is invalidated according to a processor mode when an invalidation operation is performed. The processor mode is one of execution in a virtual machine (VM) and execution not in a virtual machine. The invalidation operation belongs to a non-empty set of invalidation operations composed of a union of (1) a possibly empty set of operations that invalidate a variable number of TLB entries, (2) a possibly empty set of operations that invalidate exactly one TLB entry, (3) a possibly empty set of operations that invalidate the plurality of TLB entries, (4) a possibly empty set of operations that enable and disable use of virtual memory, and (5) a possibly empty set of operations that configure physical address size, page size or other virtual memory system behavior in a manner that changes the manner in which a physical machine interprets the TLB entries.

Abstract translation: 本发明的一个实施例是使翻译后备缓冲器（TLB）中的条目无效的技术。 处理器中的TLB具有多个TLB条目。 当执行无效操作时，每个TLB条目与虚拟机扩展（VMX）标签字相关联，指示相关联的TLB条目是否根据处理器模式而无效。 处理器模式是虚拟机（VM）中的执行之一，而不是虚拟机中的执行。 无效操作属于一个无效的无效操作集合，它由（1）可能为空的操作集合组合，使一组可变数量的TLB条目无效，（2）一组可能的空白操作，使一个TLB无效 条目，（3）使多个TLB条目无效的可能的一组操作，（4）启用和禁用虚拟存储器的使用的可能的一组可能的空操作，以及（5）配置物理的可能的一组操作 地址大小，页面大小或其他虚拟内存系统行为，以改变物理机器解释TLB条目的方式。

Abstract: In one embodiment, a method includes transitioning control to a virtual machine (VM) upon receiving a request from a virtual machine monitor (VMM), determining that the request to transition control is associated with a request to be informed of an open event window, performing an event window check to determine whether an even window of the VM is open, and transitioning control to the VMM if the event window check indicates that the event window of the VM is open.

Abstract: In one embodiment, an apparatus includes a set of multiplex blocks coupled with an interrupt controller and multiple interrupt request lines, and a virtual machine monitor block (VMM) coupled to the set of multiplex blocks. Each multiplex block corresponds to a distinct interrupt request line. Each multiplex block is to route the interrupt request signal received via the corresponding interrupt request line either to the interrupt controller or the VMM block depending on a current configuration value of this multiplex block.

Abstract: In one embodiment, a request to transition control to a virtual machine (VM) is received from a virtual machine monitor (VMM) and a determination is made as to whether the VMM has requested a delivery of a fault to the VM. If the determination is positive, the fault is delivered to the VM when control is transitioned to the VM.

Abstract: In one embodiment, a method for supporting address translation in a virtual-machine environment includes creating a guest translation data structure to be used by a guest operating system for address translation operations, creating an active translation data structure based on the guest translation data structure, and periodically modifying the content of the active translation data structure to conform to the content of the guest translations data structure. The content of the active translation data structure is used by a processor to cache address translations in a translation-lookaside buffer (TLB).
