Abstract: An example device including virtualized graphics processing units (vGPUs) is configured to respectively receive commands from a plurality of operating systems (OSs). A vGPU scheduler is configured to schedule an order and times for processing of the commands by a GPU. The vGPU scheduler can, for example, schedule the order and times such that a command from a foreground OS (FG OS) among the plurality of OSs is scheduled to be processed first.

Abstract: The present invention provides a method for managing dynamic memory between a host operating system and a guest operating system in an electronic device for executing a multi-operating system. A method for managing dynamic memory enables, with respect to the available memory state of a host operating system and a guest operating system, direct determination of transmission of guest operating system memory to the host operating system by the guest operating system and recovery of the transmitted memory to the guest operating system and enables a request for execution to the host operating system. Moreover, with respect to memory availability state information of the guest operating system, memory information of the host operating system can be collected at a designated collecting interval by means of a request to the host operating system. Also, the host operating system can allocate dynamic memory of the guest operating system with respect to a request from the guest operating system.

Abstract: Disclosed is a method of displaying a notification on a device with a plurality of operating systems (OSes) installed therein. The method includes identifying a first OS displayed on a first display of the device among the plurality of OSes, detecting a notification generated in a second OS running in a background of the device among the plurality of OSes, converting the generated notification based on a preset format of the first OS when the notification is generated, and displaying the converted notification on the first display on which the first OS is displayed.
