Intel Speed Shift

Intel Speed Shift


I am looking at intel_pstate and get some questions.  It would be very nice, if you can answer them.

1. 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?

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?
