Another suggestion is: We tried hard to remove all throttling logic from thermal_core.c. May be we should include this kind of logic in step_wise.c ? Rui/Eduardo: Any thoughts on this ?

Trend evaluation seems like a good complementary idea. However, I would also like to have the relative temperature drop measurement (if possible) like above (to 75% of the first trip point). Then I would be more confident, that everything cooled down and that I can start boost again. > > > + tz->overheated = false; > > + if (tz->boost_polling) { > > + tz->boost_polling = false; > > + tz->polling_delay = 0; > > + monitor_thermal_zone(tz); > > + } > > Overall, I believe this will work well only if the thermal zone is > CPU. My assumption: When I enable boost at CPU, then I also shall cool down the CPU. And the CPU zone seemed a natural choice.

It sounds interesting (since ->throttle at thermal_core.c is called always when needed), but I'm afraid of a code duplication when one use Boost with fair_share or other thermal governor. > Rui/Eduardo: Any thoughts on this ? > > Thanks, > Durga > > + > > + cpufreq_boost_trigger_state(1); > > + return; > > + } > > + } > > + > > thermal_zone_device_update(tz); > > } > > > > diff --git a/include/linux/thermal.h b/include/linux/thermal.h > > index a386a1c..f1aa3c2 100644 > > --- a/include/linux/thermal.h > > +++ b/include/linux/thermal.h > > @@ -172,6 +172,8 @@ struct thermal_zone_device { > > int emul_temperature; > > int passive; > > unsigned int forced_passive; > > + bool overheated; > > + bool boost_polling; > > const struct thermal_zone_device_ops *ops; > > const struct thermal_zone_params *tzp; > > struct thermal_governor *governor; > > -- > > 1.7.10.4 > > > > -- > > To unsubscribe from this list: send the line "unsubscribe linux-pm" > > in the body of a message to majordomo@vger.kernel.org > > More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-pm" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

So, for the time being, (as part of this patch series) I am Okay to have this code in thermal_core.c. From the thermal subsystem perspective, we will (need to) work out a better/ cleaner/easier approach for this later.

Dear Zhang, Eduardo Do you have any comments/feedback for me regarding this thermal framework related patch?
