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: Systems, methods, and computer readable media to reduce latency in a graphics processing pipeline of an electronic device having a touch-sensitive input device and a display are described herein. In one embodiment, the method includes obtaining a temporal sequence of multi-touch scan data, processing the multi-touch scan data, determining an “optimal” time to deliver the processed multi-touch scan data to the relevant application(s) running on the device for processing, animating the resultant graphical changes that are determined by the application(s) based on the multi-touch input, and rendering the determined graphical changes to a frame buffer. In some embodiments, determining the “optimal” time for delivering the processed multi-touch scan data to the relevant application(s) comprises measuring the performance of the relevant application(s) in order to determine how likely it is that the necessary processing of the received multi-touch information may be completed before the conclusion of the next vertical blanking interval.

Abstract: This disclosure pertains to systems, methods, and computer readable medium for mapping particular user interactions, e.g., gestures, to the input parameters of various image processing routines, e.g., image filters, in a way that provides a seamless, dynamic, and intuitive experience for both the user and the software developer. Such techniques may handle the processing of both “relative” gestures, i.e., those gestures having values dependent on how much an input to the device has changed relative to a previous value of the input, and “absolute” gestures, i.e., those gestures having values dependent only on the instant value of the input to the device. Additionally, inputs to the device beyond user-input gestures may be utilized as input parameters to one or more image processing routines. For example, the device's orientation, acceleration, and/or position in three-dimensional space may be used as inputs to particular image processing routines.

Abstract: Disclosed herein is a technique for implementing a secure lock screen on a computing device. The secure lock screen is configured to permit particular applications to display their content—such as main user interfaces (UIs)—while maintaining a desired overall level of security on the computing device. Graphics contexts, which represent drawing destinations associated with the applications, are tagged with entitlement information that indicates whether or not each graphics context should be displayed on the computing device when the computing device is in a locked-mode. Specifically, an application manager tags each application that is initialized, where the tagging is based on a level of entitlement possessed by the application. In turn, a rendering server that manages the graphics contexts can identify the tagged entitlement information and display or suppress the content of the applications in accordance with their entitlements.

Abstract: Prior art attempts to manage authority designation in GUI-based computer systems have set up various “handshaking” schemes between a graphics management system, such as a window server, and the various processes that are attempting to offer and accept access to each other. However, these schemes have certain limitations. In particular, when windows are used as the “fundamental basis” for implementing authority designation, events that should treat all content within a window identically can't do so because, even though all content in the window may appear to be “owned” by the window, there may be some other process that is actually rendering the content to some portion of the window. Thus, described herein are systems and methods to manage authority designation and event handling within “hierarchical” GUIs using “handshaking” schemes that are secure, sub-window granular, and that generalize recursively when applied to the various graphical layers used to construct the windows.
