| Zusammenfassung: | Processor-based systems may use more than one software routine or method to access a write-back cache. If the methods are inconsistent, the data in the write-back cache may be incoherent with a disk drive that is being cached. A method and apparatus for preserving coherent data in a write-back disk cache may include writing dirty cache lines to a disk drive and monitoring for disk write requests, prior to a disk driver loading. |
