VDom: Fast and Unlimited Virtual Domains on Multiple Architectures

Abstract
Hardware memory domain primitives, such as Intel MPK and ARM Memory Domain, have been used for efficient in-process memory isolation. However, they can only provide a limited number of memory domains (16 domains), which cannot satisfy the compelling need for more isolated domains inside the address space of a process. Existing solutions to virtualize memory domains are either intrusive (need the modification to existing hardware), or incur a large performance overhead.
