CPU frequency scaling driver not changeable [SOLVED]

jl2 · 2022-12-15 19:28:46

I have a amd ryzen 6800u, which scales from 0.4 to 4.77 Ghz. the base freq is 2.7 Ghz.
Boosting is supported with the amd_pstate driver
The amd_pstate driver worked (and survived reboots) until after a reboot, i realised that it had changed the scaling driver to acpi_cpufreq, which doesn't seem able to boost the CPU (more below) and sets the BIOS limit from 0.4 to 1.6 Ghz.
I have tried blacklisting it and explicitly load the amd_pstate via mkinitcpio unsuccesfully.
lsmod does not show either of the drivers.

cpupower frequency-info:

analyzing CPU 0:
  driver: acpi-cpufreq
  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency:  Cannot determine or is not supported.
  hardware limits: 1.60 GHz - 4.77 GHz
  available frequency steps:  2.70 GHz, 1.80 GHz, 1.60 GHz
  available cpufreq governors: conservative ondemand userspace powersave performance schedutil
  current policy: frequency should be within 1.60 GHz and 2.70 GHz.
                  The governor "ondemand" may decide which speed to use
                  within this range.
  current CPU frequency: Unable to call hardware
  current CPU frequency: 1.60 GHz (asserted by call to kernel)
  boost state support:

Add initcall_blacklist=acpi_cpufreq to your kernel parameters

jl2 · 2022-12-16 05:43:08

Didn't help, still running on acpi-cpufreq

V1del · 2022-12-16 09:35:45

it shouldn't, but maybe the initcall does not convert hyphens and underscores did you try initcall_blacklist=acpi-cpufreq instead as well?

jl2 · 2022-12-17 06:23:15

Yes, i also did that, but no change in the result.
Should I try it on a different kernel(I'm running linux-xanmod)?
Also, why is neither the amd_pstate nor the acpi_cpufreq driver shown in Lsmod?

Built-ins are directly built into the kernel and not loadable anymore thus won't show in lsmod. Acpi-cpufreq shouldn't be a built-in on a standard kernel, so yes test a standard kernel

if you did not yet find the solution: With Kernel 6.1 the behaviour changed. You now need to set

amd-pstate=passive

as boot parameter to be able to load it

also, will a module, which is built in to the initramfs be shown with lsmod?

If it's a loadable module yes it will show even if included in the initramfs, not sure about the remaining issue, sorry

You don't need to blacklist anything.
Read my post above, there was a change with 6.1:

The kernel parameter did the trick, thanks.
