            Bug ID: 215574
           Summary: Frequency boost disabled by default on Asus PN50
           Product: Power Management
           Version: 2.5
    Kernel Version: 5.17.0-rc2+
          Hardware: x86-64
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: cpufreq
          Assignee: [email protected]
          Reporter: [email protected]
        Regression: No

On Asus PN50 with the latest available BIOS 0623 - turbo boost is disabled by default on boot and CPU only goes from 1.4Ghz to 1.8Gz non turbo frequencies resulting in noticeable sluggishness vs Windows which seems to be able to boost to 4.2Ghz.

If I manually echo 1 > /sys/devices/system/cpu/cpufreq/boost or put it in udev rules for that matter - things work as expected, processor boosts to 4.x Ghz, fans kick in and system is snappier.
