Abstract
A processor of an aspect includes a decode unit to decode an aperture access instruction, and an execution unit coupled with the decode unit. The execution unit, in response to the aperture access instruction, is to read a host physical memory address, which is to be associated with an aperture that is to be in system memory, from an access protected structure, and access data within the aperture at a host physical memory address that is not to be obtained through address translation. Other processors are also disclosed, as are methods, systems, and machine-readable medium storing aperture access instructions.
