Subject: pwoertop frequencies not ordered descending

Message-ID: <54C6474E.6080805@gmx.de> (raw)
With the ACPI driver (and CPU governor "ondemand") the output of powertop looked always fine.
However with the P-State driver I do now have this output at 2 hardened 64 bit Gentoo Linux systems:
PowerTOP 2.6 Overview Idle stats Frequency stats Device stats Tunables

Is this (partly ?) related to the kernel or just an issue of powertop ?
