--- Comment #20 from Artem S. Tashkinov (aros@gmx.com) ---
I'm a little bit lost in all of that.

Originally I was looking for a way to control my APU TDP(TTP) and maximum
temperature threshold *without* using ryzenadj because CPU control registers
are locked in secure boot mode.

The second issue is my 7840HS never going above 4.5GHZ either in Linux or
Windows.

Trusted Execution Environment (TEE) or not I wonder if my firmware is simply
buggy and there's an artificial CPU frequency limit set by HP for no reasons
and whether I should continue pushing them to released fixed firmware or if
your fellow AMD engineers could politely ask HP to remove the restriction.
