Abstract
The present disclosure describes methods and systems for secure debugging and profiling of a computer system. Some illustrative embodiments may include a system including a processor with a first processing stage and a first attribute register associated with the first processing stage, and including a memory system coupled to the processor. An instruction and an attribute value are stored within the memory system, wherein the instruction is loaded into the first processing stage and the attribute value is loaded into the first attribute register. Export of debug and profiling data from the first processing stage is disabled if the attribute value in the first attribute register indicates that the instruction in the first processing stage is a secure instruction, and further indicates that secure emulation is disabled.
