摘要： Preemptive scheduling enclaves as disclosed herein support both cooperative and preemptive scheduling of in-enclave (IE) thread execution. These preemptive scheduling enclaves may include a scheduler configured to be executed as part of normal hardware interrupt processing by enclave threads. The scheduler identifies an IE thread to be scheduled and modifies enclave data structures so that, when the enclave thread resumes processing after a hardware interrupt, the identified IE thread is executed, rather than the interrupted IE thread.

摘要： A computing platform may include heterogeneous processors (e.g., CPU and a GPU) to support sharing of virtual functions between such processors. In one embodiment, a CPU side vtable pointer used to access a shared object from the CPU 110 may be used to determine a GPU vtable if a GPU-side table exists. In other embodiment, a shared non-coherent region, which may not maintain data consistency, may be created within the shared virtual memory. The CPU and the GPU side data stored within the shared non-coherent region may have a same address as seen from the CPU and the GPU side. However, the contents of the CPU-side data may be different from that of GPU-side data as shared virtual memory may not maintain coherency during the run-time. In one embodiment, the vptr may be modified to point to the CPU vtable and GPU vtable stored in the shared virtual memory.
摘要翻译：计算平台可以包括异构处理器（例如，CPU和GPU），以支持这些处理器之间的虚拟功能的共享。在一个实施例中，如果GPU侧表存在，则用于从CPU 110访问共享对象的CPU侧vtable指针可用于确定GPU vtable。在另一实施例中，可以在共享虚拟存储器内创建可能不维持数据一致性的共享非相干区域。存储在共享非相干区域内的CPU和GPU侧数据可以具有与CPU和GPU侧所见相同的地址。然而，CPU侧数据的内容可能与GPU侧数据的内容不同，因为共享虚拟存储器可能在运行期间不能维持一致性。在一个实施例中，可以修改vptr以指向存储在共享虚拟存储器中的CPU vtable和GPU vtable。

摘要： A page table entry dirty bit system may be utilized to record dirty information for a software distributed shared memory system. In some embodiments, this may improve performance without substantially increasing overhead because the dirty bit recording system is already available in certain processors. By providing extra bits, coherence can be obtained with respect to all the other uses of the existing page table entry dirty bits.

摘要： Embodiments of the invention provide a programming model for CPU-GPU platforms. In particular, embodiments of the invention provide a uniform programming model for both integrated and discrete devices. The model also works uniformly for multiple GPU cards and hybrid GPU systems (discrete and integrated). This allows software vendors to write a single application stack and target it to all the different platforms. Additionally, embodiments of the invention provide a shared memory model between the CPU and GPU. Instead of sharing the entire virtual address space, only a part of the virtual address space needs to be shared. This allows efficient implementation in both discrete and integrated settings.
摘要翻译：本发明的实施例提供了一种用于CPU-GPU平台的编程模型。特别地，本发明的实施例为集成和分立设备提供统一的编程模型。该模型还适用于多个GPU卡和混合GPU系统（分立和集成）。这允许软件供应商编写单个应用程序堆栈并将其定位到所有不同的平台。另外，本发明的实施例提供了CPU和GPU之间的共享存储器模型。而不是共享整个虚拟地址空间，只需要共享虚拟地址空间的一部分。这允许在离散和集成设置中有效实现。

摘要： Systems and methods may provide for using audio output device driver logic to maintain one or more states of an audio accelerator in a memory store, detect a suspend event, and deactivate the audio accelerator in response to the suspend event. In addition, firmware logic of the audio accelerator may be used to detect a resume event with respect to the audio output accelerator, and retrieve one or more states of the audio accelerator directly from the memory store in response to the resume. Thus, the retrieval of the one or more states can bypass the driver logic.
