i did not quite understand the down differential part. Can any one explain it. What role it plays while scaling down. because if the load is less than (upthresold - down_differential) it scales down everytime the sample duration. this is what i understood.
thank you. /Ryan On Thu, Sep 26, 2013 at 7:51 PM, Ryan <ryanphilip...@googlemail.com> wrote: > Hi, > > I wanted to know if the ondemand governor scales down the frequency to > a minimum when the load comes below up_threshold? > > I understand that > > 1) Every now and then, the governor work queue runs and checks for > "load" in percentage. > > If load > 95 ; it bumps the frequency to maximum; > > ie. if the idle time is less than 5% ; the cpu will run at maximum > > > 2) If load < 90% ; it bumps the frequency down little bit; > > It continues to do this till minimum; So the rate of decrease of > frequency to minimum is very slow; > > So, the frequency decrease to minimum will take a long time to > reach minimum (depends on sampling time). > > > > > Is this correct. > > > /Ryan _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
