            Bug ID: 101241
           Summary: cpufreq ondemand not work in my system
           Product: Power Management
           Version: 2.5
    Kernel Version: 2.6.32
          Hardware: x86-64
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: cpufreq
          Assignee: cpufreq@vger.kernel.org
          Reporter: jakepain@gmail.com
        Regression: No

I want to use cpufreq "ondemand" policy to change the CPU frequency dynamiclly.

But when I insmod the powernow-k8 driver, it detected below data

Jul  9 11:11:43 localhost kernel: powernow-k8: Found 1 AMD GX-416RA SOC        
                       (4 cpu cores) (version 2.20.00)
Jul  9 11:11:43 localhost kernel: powernow-k8:    0 : pstate 0 (1600 MHz)
Jul  9 11:11:43 localhost kernel: powernow-k8:    1 : pstate 1 (1600 MHz)
Jul  9 11:11:43 localhost kernel: powernow-k8:    2 : pstate 2 (1600 MHz)
Jul  9 11:11:43 localhost kernel: powernow-k8:    3 : pstate 3 (1600 MHz)
Jul  9 11:11:43 localhost kernel: powernow-k8:    4 : pstate 4 (1600 MHz)
Jul  9 11:11:43 localhost kernel: powernow-k8:    5 : pstate 5 (1600 MHz)

Why the CPU frequency is fixed? is it caused by BIOS setting?
Is there some methods to modify the limit in software not BIOS?

Thanks

are you using acpi-cpufreq driver?

plz provide following log with latest  4.4-rc1 if possible

skywalker@sky-lake:/$ grep . /sys/devices/system/cpu/cpu0/cpufreq/*

thank you

Yu

sorry I misread your log, it is related to powernow-k8 driver.. I'm not
familiar with it..
How about the result after you
stress -c 4 ?
