trappy.devfreq_power module¶

Process the output of the devfreq_cooling devices in the current directory’s trace.dat

class trappy.devfreq_power.DevfreqInPower(parse_raw=False)[source]¶

Process de devfreq cooling device data regarding get_power in an FTrace dump

get_all_freqs()[source]¶

Return a pandas.DataFrame with the frequencies for the devfreq device

The format should be the same as the one for CpuInPower().get_all_freqs().

Note

Frequencies are in MHz.

name = 'devfreq_in_power'¶: The name of the pandas.DataFrame member that will be created in a trappy.ftrace.FTrace object

unique_word = 'thermal_power_devfreq_get_power:'¶: The event name in the trace

class trappy.devfreq_power.DevfreqOutPower(parse_raw=False)[source]¶

Process de devfreq cooling device data regarding power2state in an ftrace dump

get_all_freqs()[source]¶

Return a pandas.DataFrame with the output frequencies for the devfreq device

The format should be the same as the one for CpuOutPower().get_all_freqs().

Note

Frequencies are in MHz.

name = 'devfreq_out_power'¶: The name of the pandas.DataFrame member that will be created in a trappy.ftrace.FTrace object

unique_word = 'thermal_power_devfreq_limit:'¶: The event name in the trace
