--- Comment #15 from Artem S. Tashkinov (aros@gmx.com) ---
OK, I'm now running the system with the patched amd-pmf driver.

I've no idea what the power profile daemon is.

Is there a /sys interface to alter power profiles?

There are over 1000 files in /sys named '*power*', I'm lost and not a lot
called "profile".

There's

/sys/firmware/acpi/platform_profile which now contains "balanced".

/sys/firmware/acpi/platform_profile_choices contains:

low_power balanced performance

OK, let's try "performance". Still stuck at 4.5GHz.

There's also /sys/firmware/acpi/pm_profile which has "2" in it. No idea what
that is.

P.S.

What's worst of all I cannot make my touchpad work.

With Fedora's kernel I get this:

With my custom compiled kernel I get none of these messages. I'm missing some
kernel options obviously but I've no idea which.
