Abstract:
A method is described. The method includes executing a memory access instruction for a software process or thread. The method includes creating a memory access request for the memory access instruction having a physical memory address and a first identifier of a realm that the software process or thread execute from. The method includes receiving the memory access request and determining a second identifier of a realm from the physical memory address. The method also includes servicing the memory access request because the first identifier matches the second identifier.
