Hi Dirk,
FYI, we noticed the below changes on commit
1abc4b20b85b42e8573957e54b193385cf48b0d6
("cpufreq / intel_pstate: remove idle time and duration from sample and
calculations"):
This commit was a LONG time ago. How does this compare to the current state of
the driver?
This functionality was added back in commit fcb6a15c2e7e76
