FR: set up values for battery and AC (TLP integration)

[alexgallotta]

It would be great to have an integration with TLP. In this way it would be easier to change settings in AC and battery mode TLP offers tons of settings (from tlp-stat):

+++ Configured Settings: /etc/default/tlp
CPU_SCALING_GOVERNOR_ON_AC=performance
CPU_SCALING_GOVERNOR_ON_BAT=powersave

and info about where/what to customize

/sys/devices/system/cpu/cpu0/cpufreq/scaling_driver    = intel_pstate
/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor  = performance
/sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors = performance powersave
/sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq  =   800000 [kHz]
/sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq  =  4000000 [kHz]
/sys/devices/system/cpu/cpu0/cpufreq/energy_performance_preference = performance
/sys/devices/system/cpu/cpu0/cpufreq/energy_performance_available_preferences = default performance balance_performance balance_power power

Integrate it how? The settings you are mentioning (scaling_governor, scaling_min_freq, scaling_max_freq, energy_performance_preference) are already in the widget. What more do you need? A use case would be useful (ie: "I want to be able to do this and this and that through the widget")

Sorry I was confusing. I meant only

In this way it would be easier to change settings in AC and battery mode

so to give the chance to set up some on-battery settings and on-AC settings. It might be out of scope if this widget should only change settings in a specific moment, while a proper TLP ui should be appropriate

[jsalatas]

Would CPU profiles (see issue #26) work for you?

[alexgallotta]

That will be handy yes

I think this can be closed. Configuring CPU for AC and non-AC mode from TLP would do the job, so it's probably counter productive to have the same feature here
