└─>Current frequency derived from HW provided feedback
In linux kernel since version 6.6.86 (release Date: 2025-04-07)
This determines whether the scaling_cur_freq sysfs attribute returns
the last requested frequency or a more precise value based on hardware
provided feedback (as architected counters).
Given that a more precise frequency can now be provided via the
cpuinfo_avg_freq attribute, by enabling this option,
scaling_cur_freq maintains the provision of a counter based frequency,
for compatibility reasons.
