摘要： A host computing device has a virtual machine (VM) instantiated thereon. The VM has a virtual application instantiated thereon and a virtual processor. The host also has a virtual machine monitor (VMM) instantiated thereon to oversee the VM and to intercept instructions from a virtual entity comprising one of the virtual application and the VM to the virtual processor of such VM. The virtual entity becomes self-aware of the virtual status thereof based on a self-aware flag as obtained from the VMM, and based thereon obtains particular virtual metadata from a Synthetic range of the virtual processor by way of the VMM to operate efficiently. The Synthetic range of the virtual processor is implemented by the VMM and does not correspond to any defined range of the physical processor corresponding to the virtual processor.

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： 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： 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.
