The method comprises intercepting a request for a first DMA operation forwarded by a first device to a second device; and translating a guest address included in the request to a first address according to a mapping referencing a memory frame in a memory of the second device. A local MMU increments a first reference count indicating number of active DMA operations directed to the memory frame and a second reference count indicating number of remote MMUs that have mapped the memory frame."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Direct memory access in a computing environment","description":"A method of address translation in a computing system providing direct memory access (DMA) by way of one or more remote memory management units (MMUs) is provided.
