New: cpufreq ondemand not work in my system
https://bugzilla.kernel.org/show_bug.cgi?id=101241
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: [email protected]
Reporter: [email protected]
Regression: NoI 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
