Abstract: Techniques may include launching an application and inserting a dynamic library into the application. An intercept wait function can intercept a target thread's call for a semaphore wait function. The semaphore wait function may request adding the target thread to a wait queue. The wait list of a table may be checked for the target thread. The table can store entries in the wait list or a signal list where an entry may include a quality-of-service category and a hang flag for a thread. The entry representing the target thread may be created after determining that the entry is not in the wait list. The semaphore wait function can enqueue the target thread to the wait queue. The target thread can be compared to entries in the signal list. The hang flag for the entry representing the target thread can be updated based on the comparison.

Abstract: Circuits, methods, and apparatus that may estimate the power being consumed by an OLED display screen of an electronic device, may provide further information about that power usage, may modify or change functions performed by the electronic device based on that power usage, and may inform an application's developer about the amount of power being used by the electronic device while the electronic device is running the application. One example may estimate the power being used by an OLED display screen of an electronic device by determining the content of images being displayed during a duration. The estimated power may then be presented to a user. The estimated power may be used in decisions to modify or change parameters of the screen or other device components.

Abstract: When queuing work items for asynchronous execution, the approaches set forth herein enable a debugger to provide more meaningful and complete stack trace information for enqueued work items. An example system identifies a work item to be enqueued for asynchronous execution as a separate thread during runtime of a program. Upon enqueuing the work item in an execution queue, the system captures pre-queue stack trace information associated with the work item, and associates the pre-queue stack trace information with the work item. The system removes the work item from the execution queue for execution, wherein the execution is associated with current stack trace information separate from the pre-queue stack trace information. Upon detecting an event associated with executing the work item, the system merges the pre-queue stack trace information with the current stack trace information to yield a merged stack trace.

Abstract: Among other disclosed subject matter, a method includes providing a user interface allowing the insertion of elements into a document flow comprising static and dynamic elements, the user interface presenting a graphical depiction of the document that is dynamically altered by the insertion of the element, wherein the dynamically altered appearance of the document correctly reflects the position and type of the inserted element and rearranges all existing static and flow elements of the document around the inserted element.
