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： An advanced configuration and power management system is described which supports an unload command by identifying those objects that are to be unloaded and, rather than simply attempting to delete the objects, detaches them from the namespace while keeping them in memory in a location accessible by the system. In this way, the system avoids the problem of trying to synchronize accesses to the objects, yet the objects not longer exist in the tree, so namespace collisions are avoided.
摘要翻译： 描述了一种高级配置和电源管理系统，其通过识别要卸载的对象来支持卸载命令，而不是简单地尝试删除对象，而将它们从命名空间中分离出来，同时将它们保持在存储器中可访问的位置 系统。 以这种方式，系统避免了尝试同步对对象的访问的问题，但是对象不再存在于树中，因此可以避免命名空间冲突。

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： A system, methodology and/or computer architecture that facilitates processing device interrupts (including level-triggered interrupts) in a user-mode process is provided. The kernel interrupt handler can cause a dedicated thread in the process to wake and invoke the driver interrupt service routine. This thread can then return control to the kernel interrupt handler. In addition to processing interrupts in an isolated mode, the context switching technique could be used in any isolated environment to process interrupts via dedicated execution context methods.

摘要： Techniques enable creation of a preview license for digital content. In some instances, the preview license indicates that it allows a content-consuming device to consume less than all of the content. This preview license may create a list specifying multiple portions of the digital content that the content-consuming device may consume. These techniques may also present to a device user an offer to purchase rights to consume all of the digital content after consumption of the preview-licensed portion(s). In other instances, a content server may embed the preview license into a content package that contains the digital content, allowing the server to distribute the package to multiple devices. In still other instances, the preview license may be bound to a domain rather than to individual devices. This allows member devices to share the digital content and the preview license, such that each member device may enjoy the preview experience.

摘要： Encrypted content streaming is provided by a method comprising holding an encrypted content stream that is cryptographically encrypted from a content stream with a content key, and holding an encrypted content key that is cryptographically encrypted from the content key with one or more blackout encryption keys. Each blackout encryption key is paired to a blackout decryption key corresponding to a specific audience, and each blackout decryption key is obtainable by audiences other than the specific audience corresponding to the blackout decryption key. The method further comprises serving the encrypted content stream to the plurality of different audiences. The encrypted content stream is embedded with a leaf license comprising the encrypted content key, and the encrypted content key is cryptographically decryptable by audiences having the one or more blackout decryption keys paired to the one or more blackout encryption keys.

摘要： Techniques enable seamless movement and consumption of licensed digital content amongst multiple devices. In some embodiments, these techniques allow establishment of a domain capable of having multiple member devices. Each member device of the domain typically comprises a content-consuming device such as a personal computer, a portable media player, or the like. These techniques enable a license associated with digital content to bind to a domain rather than an individual device. As such, each member device of the domain may contain a domain identity and, with the identity, may consume the content with use of the license and in accordance with policy described in the license. These tools may also enable a member device to join multiple domains and to contain an identification of each of these multiple domains.
