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.

Memory management of data processing systems

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.

Controlling display performance using display statistics and feedback

An electronic device with a touch-sensitive surface displays a user interface of a first software application that is updated at a first display rate. While displaying a first frame of the user interface in accordance with the first display rate, the device detects respective movement of a touch input across the touch-sensitive surface. An application-independent touch processing module of the device selects a respective touch location of the touch input that was detected during the respective movement to identify as a representative touch location for the respective movement based on touch-processing criteria for the first software application, and sends to an application-specific portion of the first software application touch location information for the touch input that identifies the respective touch location as the representative touch location for the respective movement. The first software application updates the user interface in accordance with the touch location information.

Devices and methods for processing touch inputs

In some implementations, a mobile device can be configured to monitor environmental, system and user events. The occurrence of one or more events can trigger adjustments to system settings. In some implementations, the mobile device can be configured to keep frequently invoked applications up to date based on a forecast of predicted invocations by the user. In some implementations, the mobile device can receive push notifications associated with applications that indicate that new content is available for the applications to download. The mobile device can launch the applications associated with the push notifications in the background and download the new content. In some implementations, before running an application or accessing a network interface, the mobile device can be configured to check energy and data budgets and environmental conditions of the mobile device to preserve a high quality user experience.

Initiating background updates based on user activity

Disclosed are systems, methods, and non-transitory computer-readable storage media for predicting a future context of a computing device. In some implementations, a context daemon can use historical context information to predict future events and/or context changes. For example, the context daemon can analyze historical context information to predict user sleep patterns, user exercise patterns, and/or other user activity. In some implementations, a context client can register a callback for a predicted future context. For example, the context client can request to be notified ten minutes in advance of a predicted event and/or context change. The context daemon can use the prediction to notify a context client in advance of the predicted event.

Context prediction

A method of guiding a user to a suitable parking spot is a method used to aid a user in finding a suitable parking spot near a desired location. The method uses at least one remote server and a mobile computing device. The remote server manages information related to potential parking spots, and performs calculations to determine if a potential parking spot is a suitable parking spot. The mobile computing device monitors the location of the user and allows the user to interact with the method. A parking search request is sent from the mobile computing device to the remote server. Upon receiving the parking search request, the geospatial vehicle detection system is used to locate potential parking spots. At least one filtering process is used to identify suitable parking spots from the potential parking spots, before the suitable parking spots are displayed to the user.

Method of guiding a user to a suitable parking spot

Embodiments provide 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 display engine to present the one or more frames of data to the display device for display; display logic to receive a 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, wherein the request includes a first hint to indicate a complexity of the one or more frames of data and the one or more display events includes a second hint derived from the first hint; and a performance controller to adjust one or more performance related parameters for the display system based on the second hint.

Controlling display performance using display system hints

An electronic device, with a touch-sensitive surface and display, displays a user interface at a first display rate. While displaying the user interface, the device detects movement of a touch input across the touch-sensitive surface at a first detection rate that is higher than the first display rate. An application-independent touch processing module sends to an application-specific portion of the first software application touch location information for the touch input that identifies: one or more predicted locations of the touch input on the touch-sensitive surface, and one or more predicted intensity values of the touch input at one or more intensity locations of the touch input on the touch-sensitive surface. The first software application processes the touch location information and updated the user interface accordingly.

Embodiments described herein provide 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; display logic to receive a request to display the one or more frames of data, the request including a requested presentation time in which the one or more frames of data are to be displayed; and a display engine to present the one or more frames of data to the display device for display at a target presentation time, the target presentation time derived from the requested presentation time, wherein the display engine is to adjust a refresh rate of the display device based on the target presentation time of the one or more frames of data.

Controlling display performance with target presentation times

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.

Controlling display performance using animation based refresh rates

An electronic device, with a touch-sensitive surface and display, displays a user interface at a first display rate. While displaying the user interface in accordance with the first display rate, the device detects movement of a touch input, including detecting the touch input at a first set of sequential locations on the touch-sensitive surface, including a plurality of locations on the touch-sensitive surface, and predicts for the touch input a first set of one or more predicted locations on the touch-sensitive surface based on multiple locations in the first set of sequential locations. The device updates the user interface in accordance with the first set of one or more predicted locations of the touch input on the touch-sensitive surface.

An electronic device, with a touch-sensitive surface and display, displays a user interface at a first display rate. While displaying the user interface, the device detects, at a first detection rate that is greater than the first display rate, movement of a touch input at a sequence of locations on the touch-sensitive surface; and, at each of a sequence of update times, updates the user interface from a respective current state to a respective next state in accordance with a selected subset of the sequence of locations of the touch input. Each selected subset of the sequence of locations includes a plurality of locations of the touch input.
