Abstract: Examples may include a method of protecting memory and I/O transactions. The method includes allocating memory for an application, assigning a resource of a physical device to the application, assigning a process address space identifier to the assigned resource, creating a security enclave to protect the allocated memory of the application, and associating the security enclave with the process address space identifier to protect the allocated memory and the assigned resource.

Abstract: In one embodiment, an apparatus comprises a memory to store executable instructions of an operating system and a processor to identify a request for data from an application; determine whether a persistent page cache stores a copy of the data, wherein the persistent page cache is directly addressable by the processor and is to cache data of a storage device that is not directly addressable by the processor; and access the data from the persistent page cache.
