In the passive model with HWP, several power hints are supported, like performance, balance_performance, balance_power and etc. How do they differ, i.e. how is the real frequency is chosen? Is it possible to adjust them?</P> <P>2. What kind of workload attributes does HWP profile, in order to make frequency decision? Is it possible to set the profiling, like using hardware performance event?</P> <P>Thanks,&nbsp;</P> <P>Best,&nbsp;</P> <P>Bo</P> <P><SPAN style="font-size: 1em;">&nbsp;</SPAN></P> Fri, 15 Sep 2017 08:35:08 GMT Bo_W_4 2017-09-15T08:35:08Z https://community.intel.com/t5/Software-Archive/Intel-Speed-Shift/m-p/1125415#M77617 <P>Hi,&nbsp;</P> <P>I am looking at intel_pstate and get some questions. &nbsp;It would be very nice, if you can answer them.</P> <P>1.
