Hi! @pavroo
I would like to know, if the sparky 5.19.x series kernels, use AMD's P-state driver for Zen2 and Zen3 processors.
As always, thank you very much for all your work and support with SparkyLinux. (https://i.imgur.com/RKk45Tn.gif)

Anyway, if after four days there is no answer, it is clear to me that your kernels don't use AMD P-state. (https://i.imgur.com/jwFubep.gif)
Thanks anyway

The latest version of the kernel (6.1.x series)
amd_pstate driver is included by default (builtin) in the kernel itself (NO longer available as a module anymore).
➤ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver
amd-pstate
➤ sudo modinfo amd_pstate
name: amd_pstate
filename: (builtin)
license: GPL
file: drivers/cpufreq/amd_pstate
description: AMD Processor P-state Frequency Driver
author: Huang Rui <ray.huang@amd.com>
So with this change,
anyone who wants to enable it, will have to add '
amd_pstate=passive' to the kernel (
as boot parameter) in the command line.

An update about the message written above. (https://i.imgur.com/4GCd6.gif)
With versions
6.4.x and
6.5.x series
kernels, there are new options with the
amd_pstate driver.
