The options that are missing to me are the options on the indicator-
cpufreq (and on /sys, of course). Using the 6.5 kernel, the only
available options are "Desempenho" (Performance) and "Economia de
Energia" (Powersave) and they don't seem to work at all.
Using the 5.15 kernel, there are more options and (via CLI) it's
possible to enable/disable turbo.
This power profiles daemon seem to work with 6.5 kernel, but in subtle
way: when a high load starts, it waits for a bit before rising the CPU
frequencies to 4,4 GHz when set to powersave. It works, but its impact
is minimal compared to the ability of using cpufreq to be able to, for
example, disable turbo and have a set frequency.

5.15 kernel"

Title:
Power management settings on Ryzen 7 5800H are missing
Status in linux-signed-hwe-6.5 package in Ubuntu:
New
Bug description:
After the update to kernel 6.5, cpufreq no longer has options to set
most governors or frequencies. The only available options are
powersave and performance, but changing between them seem to have no
effect. Consequently, the CPU temperature is always high: while with
the 6.2 kernel it would idle at under 50°C, now with 6.5 it's idling
at 65°C. Under a load that, with the 6.2 kernel, would result in
around 80°C on CPU and 70°C on motherboard, now with the 6.5 it
results in 100°C on both CPU and motherboard (I barely can touch the
laptop because it gets so hot).
To be able to use my laptop properly, I'm having to choose the 6.2
kernel on boot time.
