2021-01-15 Thread Lukasz Luba
The simple_ondemand devfreq governor is used by quite a few devices, like GPUs, DSPs, memory controllers, etc. It implements algorithm which tries to predict the device frequency based on past statistics. There are two tunables for the algorithm: 'upthreshold' and 'downdifferential'. These
