What about the below wording? "" passive Use amd_pstate with passive mode as a scaling driver. In this mode autonomous selection is disabled. Driver requests a desired performance level and PMFW tires to match the same performance level (if it is satisfied by guaranteed performance level).

I'll rewrite this as: guided Activate guided autonomous mode. Driver requests minimum and maximum performance level and the PMFW autonomously selects a performance level in this range and appropriate to the current workload. > > Thanks. > -- Thanks & Regards, Wyes
