Members
- target
- target percentage for failed frames
- sampling_period
- error sampling interval in milliseconds
- coeff_p
- absolute value of the proportional coefficient
- coeff_i
- absolute value of the integral coefficient
- coeff_d
- absolute value of the derivative coefficient
- smoothing_shift
- absolute value of the integral smoothing factor (i.e. amount of smoothing introduced by the exponential moving average)
- sharpen_factor
- absolute value of the derivative sharpening factor (i.e. amount of emphasis given to the derivative term after low activity events)
- sharpen_duration
- duration of the sharpening effect after the detected low activity event, relative to sampling_period
- norm_offset
- amount of normalization periodically performed on the learnt rate behaviour values (lower means we should trust more what we learnt about behaviour of rates, higher means we should trust more the natural ordering of rates)
Description
Algorithm parameters, tunable via debugfs.
