powernow not working on AMD Athlon XP Mobile
I installed DFly on an old laptop with an AMD Athlon XP-Mobile processor,
unfortunately I'm unable to scale down the processor frequency, it's a
problem for me because it makes the laptop to become very hot.
First of all, I tried to load the powernow kernel module:
but it returns the following error: "powernow: no power states found".
#sysctl -a |grep px
hw.acpi.cpu.px_dom0.available: 1867 1463 1067 800 665 533
There are no .current and .target entries and indeed I'm unable to set
the frequency I need.
Note: frequency scaling works under FreeBSD.
Is there something I can do to solve the problem (or maybe to help a
kernel developer to find the bug)?
Please cc me because I'm not subscribed to the list.
Thanks for your help.
