Hi,


i got a really nasty problem with getting cpu freq scaling to work properly. Though my kernel .config seems to be configured correctly, it just
wont work.

Board is a Asus P5W DH Deluxe

uname -a:

Code:
Linux 3.8.13-gentoo #1 SMP PREEMPT Wed Jul 17 15:50:50 CEST 2013 x86_64 Intel(R) Core(TM)2 CPU 6600 @ 2.40GHz GenuineIntel GNU/Linux

What does dmesg say in relation to the cpufreq driver?

I have no dmesg output whatsoever in relation to cpufreq.

I don't want to use any of these userspace tools in the long run, but in order to see if cpufreq does work it seems to me a good idea to check this
by using either cpufrequtils or cpufreqd. But the thing is it does not work at all. Maybe i have to rebuild my whole system and see if it works then.
Is my kernel .config correct ? I dont even know what to try now, i am lost !

zgrep -e ^CONFIG_ACPI -e ^CONFIG_CPU_FREQ /proc/config.gz

Code:
CONFIG_ACPI=y
CONFIG_ACPI_SLEEP=y
CONFIG_ACPI_BUTTON=y
CONFIG_ACPI_FAN=y
CONFIG_ACPI_I2C=y
CONFIG_ACPI_PROCESSOR=y

acpitool --cpu

Code:
  CPU type               : Intel(R) Core(TM)2 CPU          6600  @ 2.40GHz
  CPU speed              : 0xd0 MHz
  Cache size             : 2404.005 KB
  Bogomips               : 4808.01
  Bogomips               : 4808.01
  Function Show_CPU_Info : could not read directory /proc/acpi/processor/
  Make sure your kernel has ACPI processor support enabled.


The overall thing is, as far as i was able to figure it out, that however the kernel
appears to be configured to provide CONFIG_CPU_FREQ=YES, ALL related programs
pretend that it IS NOT SET.

Problem persists with kernel-3.9.7-ck

acpi_cpufreq loaded? If not, tried modprobing it? If that fails, what does dmesg say right after the attempt?

Silly question, but you have enabled intel speedstep / intel enhanced speedstep in your BIOS / UEFI, right?

Just tried to find a solution to this problem myself, today (again, as I tried at least 2 times before without any success).

I guess that's what blocks it for me in some way. Mainboard is MSI P35 Neo2 FR (BIOS 1.5) with an E8400 CPU. According to my BIOS, "Intel EIST" is enabled but I still get the same error as above ("could not insert 'acpi_cpufreq': No such device"). Same for speedstep-centrino and pcc-cpufreq.

As it is enabled in BIOS without any effect I guess there's either some hardware that blocks usage or there's some BIOS bug. I didn't have the nerves to update it yet, though.
