Hello,
intel_pstate_tracer is a useful tool to analyze the performance of intel_pstate driver. We upstream out AMD P-state driver into Linux kernel recently and like to use similiar tool to tune the performance of the driver.
I modified intel_pstate_tracer.py then it could import as a module to analyze AMD P-State trace event. Other trace event also can benifit from this change once they need this tool.
intel_pstate_tracer could be used as the same way as before and the original functionality isn't broken.
Thanks, Joe
