METHOD AND ELECTRONIC DEVICE OF FILE SYSTEM PREFETCHING AND BOOT-UP METHOD

摘要

A method of file system prefetching is provided. The method is applicable to an electronic device including a volatile storage, a non-volatile storage, and multiple processors with multiple operating systems. The method includes the following steps. When a first static backup table in the non-volatile storage is not empty, copy all data in the first static backup table to a second static backup table in the volatile storage. Check whether the first static backup table includes all required data for booting one of the operating systems in a static partition of the non-volatile storage. When the first static backup table does not include all of the required data, copy a part of the remaining required data in the static partition to the first and the second static backup tables. Return to the checking step when a booting state synchronization of the operating systems is not completed yet.

1. A method of file system prefetching, applicable to an electronic device comprising a volatile storage, a non-volatile storage, and a plurality of processors with a plurality of operating systems, the method comprising:
when a first static backup table in the non-volatile storage is not empty, copying all data in the first static backup table to a second static backup table in the volatile storage; checking whether the first static backup table comprises all required data for booting one of the operating systems in a static partition of the non-volatile storage or not; when the first static backup table does not comprise all of the required data in the static partition, copying a part of the remaining required data in the static partition to the first and the second static backup tables; and when a booting state synchronization of the operating systems is not completed yet, returning to the step of checking whether the first static backup table comprises all of the required data in the static partition or not.
