was that not integrated somehow to 5.17 kernel? amd-pstate I mean. how-to
My computer freeze during update (seems only a graphical driver issue).
I wait few minutes before hard shutdown then restart.
Everything was fine and no more updates.
Install 5.18 kernel → OK
I enabled amd_pstate.shared_mem=1 in grub config.
Linux Kernel 5.18:
❯ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver
acpi-cpufreq
❯ sudo cpupower frequency-info
analyzing CPU 0:
driver: acpi-cpufreq
Switch back to Linux Kernel 5.17:
❯ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver
amd-pstate
❯ sudo cpupower frequency-info
analyzing CPU 0:
driver: amd-pstate
It looks like it is not integrated to 5.18.
Edit://
Solution:
i have theses options on boot kernels for AMD zen2+ and more , and CPPC AUTO on UEFI motherboard
amd_pstate.enable=1 amd_pstate.shared_mem=1
with version 5.17.12

acpi-cpufreqI have some issues with kernel 5.18.1, I’m using manjaro as a host for qemu vms and I’m noticing stuttering inside them, it seems due to high cpu usage.
This doesn’t happen with 5.15 or 5.17.
Running 2x old sandy bridge e5-2687w
Same issue for me too. But there is the bug/error in the log when using amd-pstate for Linux Kernel 5.17:
That is why I disabled amd-pstate.
I do not notice what is difference between amd_pstate and acpi-cpufreq.
about this point , UEFI motherboard has both options for CPU ZEN2+
for acpi-cpufreq you cant go under 2200mhz , it mean even in idle , so not good for any laptop
for amd-pstate , cppc will use sequence order cpu to use the number core with lower temp and can go to lower frequency 550Mhz , better for any laptop

Maybe you forgot to add initcall_blacklist=acpi_cpufreq_init to grub.
I do not have to set this variable to get evolution to adhere to my chosen dark theme. I’m not sure why.
In tweaks I have set the shell and legacy applications to use adwaita-maia-compact-dark theme.
adwaita-maia-compact-dark theme works, but other default dark themes e.g. Matcha-dark-aliz do not work with it.
But the old version of evolution 3.44.1-1 works fine with these different themes.

It does not work.

Does it work for you?
same result on 5.18.1 , lost acpi-cpufreq with this blacklist option
How to enable amd_pstate for AMD Zen 2+ and Linux Kernel 5.17 or 5.18 only
- Edit
/etc/mkinitcpio.confto add
MODULES=(amd_pstate)
-
sudo mkinitcpio -P linux -
Edit
/etc/default/grubto add it inGRUB_CMDLINE_LINUX_DEFAULT:
amd_pstate.shared_mem=1
-
sudo update-grub -
reboot.
-
Enable CPPC in BIOS setting.
It works for me in Linux Kernel 5.18:

it ok with kernel and added in module for mkinitcpio.conf for kernels 5.17 & 5.18 ,
amd_pstate is not in kernel 5.15 LTS and 5.10 LTS
And this doesn’t require editing your GRUB config file?
GRUB config file adds only amd_pstate.shared_mem=1 in GRUB_CMDLINE_LINUX_DEFAULT
You do not need to add amd_pstate.enable=1
Yup, my CPU needs the shared memory solution. Some of the newest Ryzen CPUs (mostly mobile) work with amd_pstate.enable=1.

because amd_pstate was / is hyped.:
watch this Video on YT: René gave good informations about this new driver:
And as I understand it right its developed for notebooks (mobile) not desktop AMD CPUs.
My power states didn’t change, though hardware limits would now allow dropping clocks down to 550 MHz:

current policy: frequency should be within 550 MHz and 4.65 GHz.
The governor "schedutil" may decide which speed to use

The three states are identical with what acpi-cpufreq provides.
My AGESA version is 1.2.0.7, so the motherboard is up-to-date. CPU is 5600X

facing this as well I switch back to acpi-cpufreq
