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.

A method for performing thread scheduling in an electronic device having a hardware processor configured for executing an operating system is provided. The operating system includes a thread scheduler and a queue manager. The method includes the following steps. In response to one of a plurality of predefined conditions is met, enable a virtual manager executed by the hardware processor. Receive a request by the thread scheduler for scheduling a thread to be executed. Mask the scheduler by the virtual manager from accessing a first queue including a plurality of first threads in a runnable state. Direct the scheduler to a first virtual queue including a first portion of the plurality of first threads in the first queue for selecting the thread to be executed. The first portion of the first threads associated with at least one application currently running. Schedule execution of the selected thread by the hardware processor.

Method and electronic device for thread scheduling

Memory management methods and systems for mobile devices are provided. A memory usage of a memory is monitored by a built-in memory management component of an OS of the device and a user-oriented memory management component. It is determined whether the memory usage of the memory is greater than a first threshold or a second threshold, wherein the second threshold is greater than the first threshold. When the memory usage of the memory is greater than the first threshold, a multi-level memory management is performed by the user-oriented memory management component. When the memory usage of the memory is greater than the second threshold, a primitive memory management is performed by the built-in memory management component.
