Abstract: One embodiment provides for a display system to generate and display data on a display device, the display system comprising one or more graphics processors to generate one or more frames of data for display on the display device; a window manager to submit a request to display the one or more frames of data; a display engine to present the one or more frames of data to the display device for display; and display logic to receive the request to display the one or more frames of data and generate one or more display events for the display engine based on the request to display the one or more frames of data, wherein the display logic is to manage a set of statistics associated with the request.

Abstract: Techniques for memory management of a data processing system are described herein. According to one embodiment, a memory usage monitor executed by a processor of a data processing system monitors memory usages of groups of programs running within a memory of the data processing system. In response to determining that a first memory usage of a first group of the programs exceeds a first predetermined threshold, a user level reboot is performed in which one or more applications running within a user space of an operating system of the data processing system are terminated and relaunched. In response to determining that a second memory usage of a second group of the programs exceeds a second predetermined threshold, a system level reboot is performed in which one or more system components running within a kernel space of the operating system are terminated and relaunched.

Abstract: Embodiments provide for a method of generating and displaying data on a display device, the method comprising receiving an input to interact with an image presented via the display; generating a sequence of frames having an animation frame rate independent of a current refresh rate of the display device; presenting configuration data to the display engine at a display time based on the requested presentation time; and dynamically refreshing the display device based on the display time to display the sequence of frames.
