Abstract: A processor for supporting secure memory intent is disclosed. The processor of the disclosure includes a memory execution unit to access memory and a processor core coupled to the memory execution unit. The processor core is to receive a request to access a convertible page of the memory. In response to the request, the processor core to determine an intent for the convertible page in view of a page table entry (PTE) corresponding to the convertible page. The intent indicates whether the convertible page is to be accessed as at least one of a secure page or a non-secure page.

Abstract: In accordance with some embodiments, a protected execution environment may be defined for a graphics processing unit. This framework not only protects the workloads from malware running on the graphics processing unit but also protects those workloads from malware running on the central processing unit. In addition, the trust framework may facilitate proof of secure execution by measuring the code and data structures used to execute the workload. If a part of the trusted computing base of this framework or protected execution environment is compromised, that part can be patched remotely and the patching can be proven remotely throughout attestation in some embodiments.

Abstract translation: 根据一些实施例，可以为图形处理单元定义受保护的执行环境。 该框架不仅保护了图形处理单元上运行的恶意软件的工作负载，还保护了这些工作负载免受中央处理单元上运行的恶意软件。 此外，信任框架可以通过测量用于执行工作负载的代码和数据结构来促进安全执行的证明。 如果该框架或受保护的执行环境的可信计算基础的一部分受到损害，那么该部分可以被远程修补，并且在一些实施例中可以通过验证远程验证修补。
