Hi Dan,
The idea with OSI mode is that HLOS will have more awareness about power sequences and hence will be able to optimise power usage better (e.g. using heuristics) if it had more control. This means having HLOS which contains right modules for a specific platform and specific use case, if we want to do a power/perf comparison between OSI and plat-coordinated modes.
While that has been the argument for pushing OSI upstream which eventually got merged after 6 years not because we had perf/power comparison data but we got fed up asking for one from the people who were pushing it. They really didn't have the platform implementing both to do the real comparison to be honest.
So are you saying you have done the analysis and have data or just assuming here. If the former, please share the data we have been waiting for nearly 7-8 years now. -- Regards, Sudeep
