[SOLVED] Can't enable amd-pstate

Allexj · 2022-04-12 11:38:28

I tried everything. I have Ryzen 5 3500U.
I have these boot parameters:
GRUB_CMDLINE_LINUX_DEFAULT="initcall_blacklist=acpi_cpufreq_init amd_pstate.enable=1 amd_pstate.shared_mem=1 zswap.enabled=0 loglevel=3 idle=nomwait iommu=pt amdgpu.ppfeaturemask=0xffffffff"

and this /etc/modprobe.d/amd.conf:
amd-pstate replace=1

And I have this line inside /etc/mkinitcpio.conf
MODULES=(amd_pstate)

Of course I did grub-mkconfig -o /boot/grub/grub.cfg and mkinitcpio -P, but nothing.

I only have accomplished to blacklist acpi-cpufreq. In fact inside /sys/devices/system/cpu/cpu0/ I have this:
cache crash_notes driver hotplug node0 subsystem uevent
cpuidle crash_notes_size firmware_node microcode power topology

and cpufreq folder is gone

Are you absolutely certain? What do you get for

cat /proc/cmdline

?

Have you enabled CPPC in your firmware?

$ cat /proc/cmdline
BOOT_IMAGE=/vmlinuz-linux root=UUID=d2311838-c8ad-4ec8-93fc-da28a6fc568e rw initcall_blacklist=acpi_cpufreq_init amd_pstate.enable=1 amd_pstate.shared_mem=1 zswap.enabled=0 loglevel=3 idle=nomwait iommu=pt amdgpu.ppfeaturemask=0xffffffff

I don't have such option in my BIOS

Also, I realized that my CPU (3500U) is a Zen+... so it's not supported......
