An identifier field of a TLB entry in the TLB cache includes a VPID and a PCID. The method includes: in response to detecting a target guest process involving an invalid address mapping relationship, obtaining a current VPID and a current PCID corresponding to the target guest process; classifying the current PCID into an invalid PCID set corresponding to the current VPID, and selecting a PCID from an available PCID set of a target virtual machine as an updated PCID; and allocating the updated PCID to the target guest process, so an updated entry for the target guest process is recorded in a TLB cache, where an identifier field of the updated entry includes the updated PCID."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and apparatuses for managing TLB cache in virtualization platform","description":"Implementations of the present specification provide a method and an apparatus for managing a TLB cache in a virtualization platform, where the virtualization platform runs a plurality of virtual mach","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11947992","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.
