The non-CPU may support virtual to physical address mapping and may thus be aware of the memory pages, which may not be pinned but may be accessed by the non-CPU. The non-CPU may notify or send such information to a run-time component such as a device driver associated with the CPU. The device driver may, dynamically, perform pinning of such memory pages, which may be accessed by the non-CPU. The device driver may even unpin the memory pages, which may be no longer accessed by the non-CPU. Such an approach may allow the memory pages, which may be no longer accessed by the non-CPU to be available for allocation to the other CPUs and/or non-CPUs."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Dynamic pinning of virtual pages shared between different type processors of a heterogeneous computing platform","description":"A computer system may support one or more techniques to allow dynamic pinning of the memory pages accessed by a non-CPU device, such as a graphics processing unit (GPU).
