[arch-general] powernow-k8 fails to load with linux 3.7.2
Hi, I just installed linux 3.7.2 from [testing] on an AMD system and noticed that powernow-k8 is not loaded. As a result, the CPU is stuck at the maximum frequency because ondemand governor is inactive. The precise model is AMD PhenomII X4 955, and modprobe error is: -------------- % modprobe -vv powernow-k8 modprobe: INFO: custom logging function 0x40ab40 registered modprobe: INFO: Failed to insert module '/lib/modules/3.7.2-1-ARCH/kernel/drivers/cpufreq/powernow-k8.ko.gz': No such device modprobe: ERROR: could not insert 'powernow_k8': No such device modprobe: INFO: context 0x21c91b0 released insmod /lib/modules/3.7.2-1-ARCH/kernel/drivers/cpufreq/powernow-k8.ko.gz -------------- Meanwhile, linux 3.6.11 works fine. Notice also, that acpi_cpufreq 3.7.2 is fine on a INtel core2duo machine. Is it only me, or others have seen this too?

Probably due to this: <http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=e1f0b8e9b04a262834ed1>.
Meanwhile, linux 3.6.11 works fine. Notice also, that acpi_cpufreq 3.7.2 is fine on a INtel core2duo machine.
Hm, I thought acpi_cpufreq should have been loaded instead, no idea why that does not happen for you. Could you try loading it manually? Cheers, Tom

Ah... yes. I am confused though, why keep powernow_k8 as a separate module as opposed to an alias?

Neither acpi_cpufreq nor powernow_k8 is loaded automatically which of course leads to failure of all custom units configuring ondemand governor via sysfs. Manually modprob'ing acpi_cpufreq does work and indeed properly scales down the frequancy, but is accompanied by an info-level kernel message "acpi-cpufreq: overriding BIOS provided _PSD data". So, if the cpufreq driver works OK for other AMD users, I'll happily blame asus... Thanks, Leonid.
Cheers,
Tom

I also have a Phenom II, and had to create /etc/modules-load.d/acpi.conf, and add acpi to it.
