Abstract
Various embodiments are generally directed to generating logs recording events related to wakelocks at application and kernel levels, and then temporally aligning graphs of those events in a visual presentation to enable debugging of wakelocks. An apparatus to debug wakelocks includes a processor component; a capture component to intercept calls associated with application level wakelocks, the intercepted calls received by an application power manager of an operating system from application routines; and a relaying component to cooperate with the application power manager to provide indications of the intercepted calls to a system log generator of the operating system coupled to the application power manager, the system log generator to generate system log data comprising indications of events associated with execution of the operating system by the processor component and the indications of the intercepted calls. Other embodiments are described and claimed.
