Satisfying memory ordering requirements between partial reads and non-snoop accesses

摘要: A method and apparatus for preserving memory ordering in a cache coherent link based interconnect light of partial non-coherent accesses is herein described. In one embodiment, accesses, such as read, implemented utilizing Read Invalidate and/or Snoop message. When peer node receives message referencing data from requesting node, the to invalidate line associated with not directly forward node. when holds referenced Modified coherency state, response receiving message, writeback home data.
