    Abstract: In a cloud gaming system or other remote video streaming system, a client device and a server coordinate to introduce an adjustable delay in the frame start timing in the frame rendering pipeline at the server to reducing vertical synchronization (VSYNC) presentation latency, and thus reduce overall frame latency. In implementations, the coordination between the client device and the server includes the client device observing the current VSYNC presentation latencies in recently processed video frames reporting this observed VSYNC presentation latency to the server. The server uses this feedback to determine a frame start delay that is then used to introduce a frame start shift for an upcoming frame and subsequent frames, thereby shifting the server rendering and encoding pipeline back so that the resulting video frames are made available to present at the client device closer to their respective VSYNC signal assertions.

    Abstract: A processing system aligns rendering timing of an application executing at a guest virtual function to world switch timing of a host virtual machine. The host virtual machine sets a world switch interval based on a number of virtual functions (VFs) that share the parallel processor and a target maximum frame rate. The processing system delays submission of jobs for a VF to the parallel processor by an offset with respect to the world switch timing to ensure that the application starts generating a job for the parallel processor before the VF gains a time slice so the job will be ready for the parallel processor when the VF gains the time slice.

    Abstract: Described is a method and apparatus for application migration between a dockable device and a docking station in a seamless manner. The dockable device includes a processor and the docking station includes a high-performance processor. The method includes determining a docking state of a dockable device while at least an application is running. Application migration from the dockable device to a docking station is initiated when the dockable device is moving to a docked state. Application migration from the docking station to the dockable device is initiated when the dockable device is moving to an undocked state. The application continues to run during the application migration from the dockable device to the docking station or during the application migration from the docking station to the dockable device.
