Abstract: Methods and systems are provided to selectively log branch trace store data associated with the execution of an application. A privilege level is received, which identifies an execution mode for a processor for which branch trace store data is to be logged to a buffer. The privilege level is used to set one or more privilege flags that permit selective branch trace store data to be logged in the buffer when the application is executed. In one embodiment, the privilege level represents a user application mode, a supervisory application mode, or a mode representing both a user application mode and a supervisory application mode.
