摘要： Embodiments of apparatuses, methods, and systems for providing multiple virtual device controllers by redirecting an interrupt from a physical device controller are disclosed. In one embodiment, an apparatus includes a processor, a physical device controller, and virtualization logic. The virtualization logic is to receive a first interrupt from the physical device controller, and in response, send a second interrupt to the processor from one of a plurality of virtual device controllers.

摘要： An apparatus for secured playback is presented. In one embodiment, the apparatus includes a controller that includes a key derivation module to manage authentication and key derivation. In one embodiment, the apparatus provides a video decryption key to a graphics engine if video data portions in a data stream are retrievable without having to decrypt the data stream. In one embodiment, the apparatus also includes a decryption module to decrypt a part of data in conjunction with an encryption key to generate video information and video data. The controller then writes an encrypted version of the video data to a video buffer of a graphics engine.

摘要： Apparatuses, methods, and systems for paging instructions for a virtualization engine to local storage. An apparatus includes a processor, a physical device controller, a virtualization engine, system memory, and local storage. The physical device controller is to be shared by a plurality of virtual machines created by a virtual machine monitor installed on a processor. The virtualization engine is to represent the physical device controller as a plurality of virtual device controllers available to be allocated to the plurality of virtual machines. The local storage is separate from the physical memory to store instructions transferred from the system memory for execution by the virtualization engine.

摘要： Embodiments of apparatuses, methods, and systems for injecting transactions to support the virtualization of a physical device controller are disclosed. In one embodiment, an apparatus includes a processor, system memory, a physical device controller, and a virtualization agent. The physical device controller is to be shared by a plurality of virtual machines created by a virtual machine monitor installed on a processor. The virtualization agent is coupled to the system memory through a first interface and coupled to the physical device controller through a second interface, to represent the physical device controller as a plurality of virtual device controllers available to be allocated to the plurality of virtual machines, and to inject transactions onto the first interface and the second interface on behalf of the plurality of virtual device controllers.
