Hello, On the topic of C-state statistics:
For 11.09 there are BP:s to A) fix powertop for ARM and B) create an Android app for running powertop in Android. By that I mean executing a reconfigured but upstreamable powertop as a service and control it from the app. I'd like input on usage patterns for powertop from all you PM experts in order to design that app as useful as possible. I'd imagine that the actual display (ncurses-based on other platforms) is cute and sure we should have it, but is it really that useful? Isn't the most important thing to get statistics between a starting and an ending time while some test or use case is executed? So I am thinking that prio 1 is "tap to start/stop logging" and saving the set of result vectors for each measurement cycle to a file that can be taken out and processed off-line into a diagram or whatever. Other ideas? /Tony On 30 August 2011 10:09, Daniel Lezcano <daniel.lezc...@linaro.org> wrote: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > > Hi, > > I did some simple cpuidle measurements and updated the wiki page. > > https://wiki.linaro.org/WorkingGroups/PowerManagement/Doc/Cpuset > > Let me know what do you think about the result. > > Is there a way to get the C-states statistics ? > > Mike, you mentioned you did a very similar cpuset configuration but you > saw only a small improvement in term of power consumption, right ?
