On-Demand Shareability Conversion In A Heterogeneous Shared Virtual Memory

摘要

The aspects include systems and methods of managing virtual memory page shareability. A processor or memory management unit may set in a page table an indication that a virtual memory page is not shareable with an outer domain processor. The processor or memory management unit may monitor for when the outer domain processor attempts or has attempted to access the virtual memory page. In response to the outer domain processor attempting to access the virtual memory page, the processor may perform a virtual memory page operation on the virtual memory page.
