The special host real address is translated to a corresponding special guest real address. Within the hashed page table, the special host real address is replaced with the corresponding special guest real address, and the corresponding special guest real address is marked as invalid and requiring special handling. Subsequent to the replacing, the special host real address is invalidated. The special guest real address and translated address information are provided to the virtual machine subsequent to the invalidating, the translated address information comprising a set of host real addresses translated to corresponding guest real addresses."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Preserving transient address translation information across a firmware assisted dump procedure","description":"Within a hashed page table maintained by a hypervisor, a special host real address configured to access a hardware device using access data intended to be invalidated is identified as part of a firmwa","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11281483","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
