Abstract: Authenticating a backup image stored on a storage device prior to restoring the backup image. A value such as a hash value is generated based on the image to be preserved. The value is stored on the storage device in a first area accessible for writing only when the computing device is in an update mode. The first area becomes read-only when the computing device is in an operating system mode. The image is stored on the storage device in a second area accessible for writing when the computing device is in the update mode or the operating system mode. When attempting to restore the image from the second area, the value from the first area is compared to another value generated at the time of the restoration for validation.

Abstract: Embodiments of the invention intelligently associate processes with core processors in a multi-core processor. The core processors are asymmetrical in that the core processors support different features or provide different resources. The features or resources are published by the core processors or otherwise identified (e.g., via a query). Responsive to a request to execute an instruction associated with a thread, one of the core processors is selected based on the resource or feature supporting execution of the instruction. The thread is assigned to the selected core processor such that the selected core processor executes the instruction and subsequent instructions from the assigned thread. In some embodiments, the resource or feature is emulated until an activity limit is reached upon which the thread assignment occurs.

Abstract: Embodiments of the invention create a virtualized storage device on a file system. Block-level storage units or clusters corresponding to the file system are defined for a storage volume associated with a computing device. Responsive to receipt of a block-level command (e.g., received via a universal serial bus), the computing device identifies a file system operation corresponding to the block-level command. The computing device performs the file system operation for the storage volume. Embodiments of the invention enable a mobile computing device to present the storage volume as a virtualized storage device to a host computing device for access while retaining control over the file system.
