Abstract
In accordance with embodiments disclosed herein, there are provided methods, systems, mechanisms, techniques, and apparatuses for implementing optional logging of debug activities in a real time instruction tracing log. For example, in one embodiment, such means may include an integrated circuit having means for initiating instruction tracing for instructions of a traced application, mode, or code region, as the instructions are executed by the integrated circuit; means for generating a plurality of packets to a debug log describing the instruction tracing; means for initiating an alternative mode of execution within the integrated circuit; and means for suppressing indication of entering the alternative mode of execution. Additional and alternative means may be implemented for selectively causing an integrated circuit to operate in accordance with an invisible trace mode or a visible trace mode upon transition to the alternative mode of execution.
