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.
摘要翻译：单个平台中的两个处理元件可以安全通信，以允许平台在一个处理元件中利用某些加密功能。诸如桥接器的第一处理元件可以使用其加密功能来请求与诸如图形引擎的第二处理元件的密钥交换。每个处理元件可以包括两个处理元件共有的全局密钥和每个处理元件唯一的唯一密钥。在系统引导的第一次引导过程中可以建立密钥交换，并且在任何硬件改变失败的情况下，在两个处理元件的整个寿命期间可以使用相同的密钥。一旦建立了安全通道，希望在没有公共 - 私人密码功能的情况下认证处理元件的任何应用程序可以与与第一处理元件共享安全通道的其他处理元件执行认证。

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： Graphics processing systems and methods are described. A graphics processing apparatus may comprise one or more graphics processing cores, a shared buffer accessible to a user mode driver (UMD) associated with an application in an unprivileged domain, the UMD to write one or more commands to the shared buffer, and a controller parse a workload in the shared buffer to identify one or more commands in the workload, the workload added by the application executing in the unprivileged domain, associate a trigger with a command in the workload, transfer the workload to one or more components of the graphics processing apparatus for execution, and upon execution of the command associated with the trigger, sample the shared buffer to identify a new workload added to the shared buffer. The one or more components of the graphics processing apparatus automatically execute the new workload added to the shared buffer.

摘要： A method, device, and system to distribute code and data stores between volatile and non-volatile memory are described. In one embodiment, the method includes storing one or more static code segments of a software application in a phase change memory with switch (PCMS) device, storing one or more static data segments of the software application in the PCMS device, and storing one or more volatile data segments of the software application in a volatile memory device. The method then allocates an address mapping table with at least a first address pointer to point to each of the one or more static code segments, at least a second address pointer to point to each of the one or more static data segments, and at least a third address pointer to point to each of the one or more volatile data segments.
