  • Publication number: 20190087216
    Abstract: This disclosure generally relates to hypervisor memory virtualization. In an example, multiple page table stages may be used to provide a page table that may be used by a processor when processing a workload for a nested virtual machine. An intermediate (e.g., nested) hypervisor may request an additional page table stage from a parent hypervisor, which may be used to virtualize memory for one or more nested virtual machines managed by the intermediate hypervisor. Accordingly, a processor may use the additional page table stages to ultimately translate a virtual memory address for a nested virtual machine to a physical memory address.

  • Publication number: 20180189317
    Abstract: Disclosed are systems and methods of accessing content items stored at a content management system by a mobile device, when the mobile device is not communicatively coupled to the content management system. The content management system can receive an indication to mark a content item (e.g., folder and the content items associated with the folder) as available to a mobile device when the mobile device is offline. The content management system can mark the content item, and any content items associated with the content item, for offline access by the mobile device and determine a synchronization schedule for the content item(s). The content management system can then initially send to the mobile device, the marked content item(s) in accordance with the synchronization schedule. While offline, the mobile device can make changes to the marked content items. The changes can be synchronized between the mobile device and content management system when the mobile device is online.

  • Patent number: 9854384
    Abstract: A sharing user of a content management system can request to share a content item in his namespace. When such a request is made, the sharing user's client device broadcasts a notification that can be received by devices that are within a limited broadcast range of the sharing client device. A receiving user's client device that is within the limited broadcast range of the sharing client device receives the broadcasted notification. Based on the notification, the receiving client device obtains a token from the sharing client device that identifies the content item being shared by the sharing user. At the request of the receiving user, the receiving client device transmits the token to the content management system and requests that the content management system add the shared content item to the receiving user's namespace with the system. The receiving user can then access the item from his namespace.
