摘要： Various mechanisms are disclosed for improving the operational efficiency of a virtual translation look-aside buffer (TLB) in a virtual machine environment. For example, one mechanism fills in entries in a shadow page table (SPT) and additionally, speculatively fills in other entries in the SPT based on various heuristics. Another mechanism allows virtual TLBs (translation look-aside buffers) to cache partial walks in a guest page table tree. Still another mechanism allows for dynamic resizing of the virtual TLB to optimize for run-time characteristics of active workloads. Still another mechanism allows virtual machine monitors (VMMs) to support legacy and enlightened modes of virtual TLB operation. Finally, another mechanism allows the VMM to remove only the stale entries in SPTs when linking or switching address spaces. All these mechanisms, together or in part, increase the operational efficiency of the virtual TLB.

摘要： Various operations are disclosed for improving the operational efficiency of interrupt handling in a virtualized environment. A virtualized interrupt controller may obviate the need for an explicit end-of-interrupt command by providing an automatic EOI capability even when a physical interrupt controller offers no such mechanism. The use of a message pending bit for inter-partition communications facilitates avoiding an EOI command of inter-processor interrupts used in inter-partition communications whenever no further messages are cued for a particular message slot. A virtualized interrupt controller facilitates the selective EOI of an interrupt even when it is not the highest priority in-service interrupt irrespective of whether a physical interrupt controller provides such functionality.

摘要： The present invention is a system for and method of providing instruction sequence compounding by (1) the virtual machine monitor's (VMM) looking ahead when an initial trap (exception) event occurs and recognizing traps within successive nearby instructions, combining and virtually executing the effects of multiple instructions while remaining inside the VMM's trap handler, and thereby minimizing the number of individual traps that would otherwise occur at each instruction and/or (2) the VMM's looking ahead when an initial context switch event occurs and recognizing context switches within successive nearby instructions, virtually combining the effects of multiple instructions and handing off this combined instruction to the host operating system, and thereby minimizing the number of individual context switches that would otherwise occur at each instruction. As a result, the number of processor cycles is reduced for exception handling and context switching in a virtual machine environment.

摘要： The present invention provides a virtualized computing systems and methods for transitioning in real time between LONG SUPER-MODE and LEGACY SUPER-MODE in the x86-64 architecture. In doing so, a virtual machine, which relies on the traditional 32-bit modes, i.e., REAL MODE and PROTECTED MODE (V86 SUB-MODE, RING-0 SUB-MODE, and RING-3 SUB-MODE), is able to run alongside other applications on x86-64 computer hardware (i.e., 64-bit). The method of performing a temporary processor mode context switch includes the steps of the virtual machine monitor's setting up a “virtual=real” page, placing the transition code for performing the processor mode context switch on this page, jumping to this page, disabling the memory management unit (MMU) of the x86-64 computer hardware, modifying the mode control register to set either the LONG SUPER-MODE bit or LEGACY SUPER-MODE bit, loading a new page table, and reactivating the MMU of the x86-64 computer hardware.

摘要： The present invention is directed to making a guest operating system aware of the topology of the subset of host resources currently assigned to it. At virtual machine boot time a Static Resource Affinity Table (SRAT) will be used by the virtualizer to group guest physical memory and guest virtual processors into virtual nodes. Thereafter, in one embodiment, the host physical memory behind a virtual node can be changed by the virtualizer as necessary, and the virtualizer will provide physical processors appropriate for the virtual processors in that node.

摘要： The present invention is a system for and method of initializing multiple virtual processors in a virtual machine (VM) environment. The method of initializing multiple virtual processors includes the steps of the host creating a multiple processor VM and activating a “starter virtual processor,” the “starter virtual processor” issuing a startup command to a next virtual processor, the virtual machine monitor (VMM) giving the target virtual processor the highest priority for accessing the hardware resources, the VMM forcing the “starter virtual processor” to relinquish control of the hardware resources, the VMM handing control of the hardware resources to the target virtual processor, the target virtual processor executing and completing its startup routine, the VMM forcing the target virtual processor to relinquish control of the hardware resources, and the VMM handing control of the hardware resources back to the “starter virtual processor” for activating subsequent virtual processors.
