The tuneable values for this governor are: +target_loads: CPU load values used to adjust speed to influence the +current CPU load toward that value. In general, the lower the target +load, the more often the governor will raise CPU speeds to bring load +below the target. The format is a single target load, optionally +followed by pairs of CPU speeds and CPU loads to target at or above +those speeds. Colons can be used between the speeds and associated +target loads for readability. For example: + + 85 1000000:90 1700000:99 + +targets CPU load 85% below speed 1GHz, 90% at or above 1GHz, until +1.7GHz and above, at which load 99% is targeted. If speeds are +specified these must appear in ascending order. Higher target load +values are typically specified for higher speeds, that is, target load +values also usually appear in an ascending order. The default is +target load 90% for all speeds. + min_sample_time: The minimum amount of time to spend at the current frequency before ramping down.
