摘要： Systems and methods are provided, whereby partitions may become enlightened and discover the presence of a hypervisor. Several techniques of hypervisor discovery are discussed, such as detecting the presence of virtual processor registers (e.g. model specific registers or special-purpose registers) or the presence of virtual hardware devices. Upon discovery, information (code and/or data) may be injected in a partition by the hypervisor, whereby such injection allows the partition to call the hypervisor. Moreover, the hypervisor may present a versioning mechanism that allows the partition to match up the version of the hypervisor to its virtual devices. Next, once code and/or data is injected, calling conventions are established that allow the partition and the hypervisor to communicate, so that the hypervisor may perform some operations on behalf of the partition. Four exemplary calling conventions are considered: restartable instructions, a looping mechanism, shared memory transport, and synchronous or asynchronous processed packets. Last, cancellation mechanisms are considered, whereby partition requests may be cancelled.

摘要： Mechanisms are disclosed herein that manage operations in virtual machine environments. A first partition can have a proxy driver object corresponding to a driver object in a second partition. The driver object can control a physical device, but because of the proxy driver object, the first partition can retain some measure of control over the physical device. The driver object can be surrounded by a first filter object beneath it, and a second filter object above it. The first filter object can provide interfaces to the driver object so that the driver object can perform various bus-related functionalities; and, the second filter object can receive redirected instructions from the first partition and provide them to the driver object, and intercept any instructions originating from within the second partition, such that if these instructions are inconsistent with policies set in the first partition, they can be manipulated.

摘要： A system and method to facilitate communication between an associated bus, such as employs a standard bus protocol, and a connector to which a removable SFF device can be attached. A desired operating mode is selected based on the device attached at the connector, such as either to pass the protocol between the bus and device generally unchanged or to implement suitable protocol conversion for such communication. Thus, by configuring the SFF device to appear as device currently supported by the bus, the SFF device can operate at the connector with native operating system support.

摘要： Various operations are disclosed for improving the operational efficiency of register handling in a virtualized environment. Some infrequently accessed software managed registers are managed lazily when switching contexts between virtual processors. The states of those registers are not saved on exit from a guest or restored on entry to the guest. Rather, guest accesses to those registers are intercepted. For some frequently accessed registers, register states are saved or restored only upon exit from a hypervisor to a different guest that that from which the hypervisor was entered. For enable-flag-gated registers, updates to a physical register value are not made unless the register is enabled. A shadow register cache may be used to speed accesses to some registers. When a shadowed register is modified, the new value is cached as a shadow copy in RAM and subsequent reads of the register are taken from the shadow copy.
摘要翻译：公开了用于提高虚拟化环境中的寄存器处理的操作效率的各种操作。在虚拟处理器之间切换上下文时，一些不经常访问的软件托管寄存器被懒惰地管理。这些寄存器的状态不会保存在从guest虚拟机退出或在进入guest虚拟机后恢复。相反，访问这些寄存器的访问被拦截。对于一些经常访问的寄存器，寄存器状态仅在从虚拟机管理程序退出到进入虚拟机监控程序的不同客户端时被保存或恢复。对于启用标志门控寄存器，除非启用寄存器，否则不会更新物理寄存器值。影子寄存器缓存可用于加速对某些寄存器的访问。当一个阴影寄存器被修改时，新的值被缓存为RAM中的卷影副本，并且从卷影副本中取出后续读取的寄存器。
