http://bugzilla.opensuse.org/show_bug.cgi?id=1201013 Bug ID: 1201013 Summary: intel_pstate: cpu frequency is always above maximum Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.4 Hardware: x86-64 OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: aturan.work@gmail.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- With intel_pstate driver, the cpu frequency never goes under maximum frequency but may go under turbo frequency so it is in range 2.80GHz - 3.40GHz.
