摘要
Systems, apparatuses, and methods related to a computer system having a page table entry containing permission bits for predefined types of memory accesses made by executions of routines in predefined domains are described. The page table entry can be used to map a virtual memory address to a physical memory address. In response to a routine accessing the virtual memory address, a permission bit corresponding to the execution domain of the routine and a type of the memory access can be extracted from the page table entry to determine whether the memory access is to be rejected.
