Comet Lake & problem cpufreq #62

Closed varlesh closed 3 years ago

varlesh commented 3 years ago

OS: KDE Neon (Ubuntu 20.04) Kernel: 5.12.0-19.3-liquorix-amd64 CPU: Intel Core i5-10400F

By default used acpi-cpufreq module : 

ls /usr/lib/modules/$(uname -r)/kernel/drivers/cpufreq/
acpi-cpufreq.ko          p4-clockmod.ko  powernow-k8.ko
amd_freq_sensitivity.ko  pcc-cpufreq.ko  speedstep-lib.ko

But acpi-cpufreq not have support this CPU:

cpupower frequency-info

  CPUs which run at the same hardware frequency: Not Available
  CPUs which need to have their frequency coordinated by software: Not Available

        10: APIC ID 0x0000000a
        11: APIC ID 0x0000000b

I try change grub config and enable intel_pstate but module not loaded and not worked too.

What's happening?

What happens when you add intel_pstate=enable into your kernel boot parameters?

Also regarding your output of cpufreq drivers, Intel P-State only works as a static in-kernel driver, so you won't see it listed in that folder. But it is built-in, but with one minor modification.

Intel P-State is disabled by default with Liquorix. You can override that by passing the parameter I mentioned above. This is a customization that's not part of mainline but necessary for Liquorix to behave the way it does.

i found problem with acpi_cpufreq - wrong bios settings. I'm enable perfomance mode on Asus and this not allow the OS to control CPU power management. Now all fine. But anyway intel_pstate not loaded. 

cat /etc/default/grub | grep intel
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_pstate=enable"
sudo update-grub
sudo reboot
ls /usr/lib/modules/$(uname -r)/kernel/drivers/cpufreq/

oops sorry, my fault:

  driver: intel_pstate

  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency:  Cannot determine or is not supported.

  available cpufreq governors: performance powersave
  current policy: frequency should be within 4.30 GHz and 4.30 GHz.
                  The governor "powersave" may decide which speed to use
                  within this range.
