    摘要: Methods and devices to augment volatile memory in a graphics subsystem with certain types of non-volatile memory are described. In one embodiment, includes storing one or more static or near-static graphics resources in a non-volatile random access memory (NVRAM). The NVRAM is directly accessible by a graphics processor using at least memory store and load commands. The method also includes a graphics processor executing a graphics application. The graphics processor sends a request using a memory load command for an address corresponding to at least one static or near-static graphics resources stored in the NVRAM. The method also includes directly loading the requested graphics resource from the NVRAM into a cache for the graphics processor in response to the memory load command.

    摘要: In some embodiments, the invention involves securing sensitive data from mal-ware on a computing platform and, more specifically, to utilizing virtualization technology and protected audio video path technologies to prohibit a user environment from directly accessing unencrypted sensitive data. In an embodiment a service operating system (SOS) accesses sensitive data requested by an application running in a user environment virtual machine, or a capability operating system (COS). The SOS application encrypts the sensitive data before passing the data to the COS. The COS makes requests directly to a graphics engine which decrypts the data before displaying the sensitive data on a display monitor. Other embodiments are described and claimed.

    摘要: The architecture and techniques described herein can improve system performance with respect to the following. Communication between two interdependent hardware engines, that are part of pipeline, such that the engines are synchronized to consume resources when the engines are done with the work. Reduction of the role of software/firmware from feeding each stage of the hardware pipeline when the previous stage of the pipeline has completed. Reduction in the memory allocation for software-initialized hardware descriptors to improve performance by reducing pipeline stalls due to software interaction.

    摘要: An apparatus, system, and method are disclosed. In one embodiment, the apparatus includes a virtualization engine on a computer platform. The virtualization engine can intercept multiple data transfer schedules from multiple virtual machines fetched from a memory by a physical Universal Serial Bus (USB) host controller on the computer platform. The virtualization engine also can merge the multiple fetched data transfer schedules into a merged data transfer schedule. The virtualization engine also can send the merged data transfer schedule to the physical USB host controller.

    摘要: An embodiment of the present invention is a technique to process faults in a direct memory access address translation. A register set stores global control or status information for fault processing of a fault generated by an input/output (I/O) transaction requested by an I/O device. An address translation structure translates a guest physical address to a host physical address. The guest physical address corresponds to the I/O transaction and is mapped to a domain. The address translation structure has at least an entry associated with the domain and domain-specific control information for the fault processing.
