An example method may include generating, by a Peripheral Component Interconnect (PCI) device comprising an input/output memory management unit (IOMMU), a first bit sequence and generating a second sequence by applying a predetermined transformation to the first bit sequence. The method may then write the second bit sequence to a memory buffer, read a first value from the memory buffer, write the first bit sequence to the memory buffer, and read a second value from the memory buffer. Responsive to determining that the second value does not match the first value, the method may associate a writable attribute with an IOMMU page table entry associated with the memory buffer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Non-interrupting portable page request interface","description":"Systems and methods for memory management for virtual machines.
