摘要： A conjugate processor includes an instruction set architecture (ISA) visible portion having a main pipeline, and an h-flow portion having an h-flow pipeline. The binary executed on the conjugate processor includes an essential portion that is executed on the main pipeline and a non-essential portion that is executed on the h-flow pipeline. The non-essential portion includes hint calculus that is used to provide hints to the main pipeline. The conjugate processor also includes a conjugate mapping table that maps triggers to h-flow targets. Triggers can be instruction attributes, data attributes, state attributes or event attributes. When a trigger is satisfied, the h-flow code specified by the target is executed in the h-flow pipeline.

摘要： A method and system for support of personal computing in a public computing infrastructure. The system including a plurality of computers to be used by patrons of a public computing infrastructure. The system also includes one or more servers coupled to the plurality of computers via a network connection. Each of the plurality of computers includes a virtual machine monitor. The virtual machine monitor has a plurality of base virtual machine images, each of the base virtual machine images is customized for a particular hardware and software configuration representing a specific computing environment. The virtual machine monitor launches one of the plurality of base virtual machine images, arbitrates access to system resources via the launched virtual machine image, stores the changes in the state of the virtual machine image when a user terminates a session, and returns a computer to an appropriate state to enable the user to resume the terminated session in subsequent sessions.

摘要： 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.

摘要： 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).

摘要： 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.

摘要： In one embodiment, a method includes transitioning control to a virtual machine (VM) from a virtual machine monitor (VMM), determining that a VMM timer indicator is set to an enabling value, and identifying a VMM timer value configured by the VMM. The method further includes periodically comparing a current value of a timing source with the VMM timer value, generating an internal event if the current value of the timing source has reached the VMM timer value, and transitioning control to the VMM in response to the internal event without incurring an event handling procedure in any one of the VMM and the VM.
