Responsive to the request, the processing device locks the virtual memory location. The processing device makes a determination to reclaim a physical memory location mapped to the virtual memory location. The processing device then determines whether the hardware device has completed the access to a physical memory location mapped to the virtual memory location. Responsive to determining that the hardware device has not completed the access to the physical memory location, the processing device implements a copy-on-write policy for the virtual memory location."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Zero copy memory reclaim using copy-on-write","description":"A processing device receives a request to provide a hardware device with direct memory access to a contents of a virtual memory location in application memory of an application.
