Rafael J. Wysocki d8f59e45fd cpufreq: intel_pstate: Fix EPP setting via sysfs in active mode ... [ Upstream commit de002c55cadfc2f6cdf0ed427526f6085d240238 ] Because intel_pstate_set_energy_pref_index() reads and writes the MSR_HWP_REQUEST register without using the cached value of it used by intel_pstate_hwp_boost_up() and intel_pstate_hwp_boost_down(), those functions may overwrite the value written by it and so the EPP value set via sysfs may be lost. To avoid that, make intel_pstate_set_energy_pref_index() take the cached value of MSR_HWP_REQUEST just like the other two routines mentioned above and update it with the new EPP value coming from user space in addition to updating the MSR. Note that the MSR itself still needs to be updated too in case hwp_boost is unset or the boosting mechanism is not active at the EPP change time.
