摘要： A method and apparatus for creating, updating, and using guest physical address (GPA) to host physical address (HPA) shadow translation tables for translating GPAs of graphics data direct memory access (DMA) requests of a computing environment implementing a virtual machine monitor to support virtual machines. The requests may be sent through a render or display path of the computing environment from one or more virtual machines, transparently with respect to the virtual machine monitor. The creating, updating, and using may be performed by a memory controller detecting entries sent to existing global and page directory tables, forking off shadow table entries from the detected entries, and translating GPAs to HPAs for the shadow table entries.

摘要： Two processing elements in a single platform may communicate securely to allow the platform to take advantage of the certain cryptographic functionality in one processing element. A first processing element, such as a bridge, may use its cryptographic functionality to request a key exchange with a second processing element, such as a graphics engine. Each processing element may include a global key which is common to the two processing elements and a unique key which is unique to each processing element. A key exchange may be established during the boot process the first time the system boots and, failing any hardware change, the same key may be used throughout the lifetime of the two processing elements. Once a secure channel is set up, any application wishing to authenticate a processing element without public-private cryptographic function may perform the authentication with the other processing element which shares a secure channel with the first processing element.

摘要： A method includes detecting a trigger condition, and in response to detecting the trigger condition, reducing a voltage applied to a graphics controller component of a memory controller. The reduction in voltage may cause the voltage to be reduced below a voltage level required to maintain context information in the graphics controller component.

摘要： A method and apparatus of deprioritizing a high priority client. An isochronous data stream request is generally referred to as a “high priority” client. These high priority requests are sensitive to time, such that a certain amount of data must be retrieved within a certain amount of time. The fetching of this data will cause increased latencies on lower priority clients making requests for data. A method and apparatus for deprioritizing a high priority client is needed to improve the efficiency in handling data traffic requests from both high priority and lower priority clients.
