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.

Sudeep
