摘要:
Secure memory repartitioning technologies are described. A processor includes a processor core and a memory controller coupled between the processor core and main memory. The main memory includes a memory range including a section of convertible pages are convertible to secure pages or non-secure pages. The processor core, in response to a page conversion instruction, is to determine from the instruction a convertible page in the memory range to be converted and convert the convertible page to be at least one of a secure page or a non-secure page. The memory range may also include a hardware reserved section are convertible in response to a section conversion instruction.
