The I/O device generates a first stash transaction request for a first data frame. The queue manager stores the first stash transaction request. When the first core executes a first thread, the queue manager stashes the first data frame to the first core by way of the IOMMU. The OS scheduler migrates the first thread from the first core to the second core and generates pre-empt notifiers. The STMMU uses the pre-empt notifiers to update the IOMMU mapping table and generate a stash replay command. The queue manager receives the stash replay command and stashes the first data frame to the second core."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System for migrating stash transactions","description":"A system for migrating stash transactions includes first and second cores, an input/output memory management unit (IOMMU), an IOMMU mapping table, an input/output (I/O) device, a stash transaction mig","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9632958","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.
