This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-trusty' to 'verification-done-trusty'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

Hi Tim,

Ok! The kernel in -proposed has those bits.

They're working.
The expected cpufreq files showed up in /sys/devices/system/cpu/cpu0/cpufreq/*,
and frequency went up and down as expected when setting governors to performance, powersave, ondemand (default).

The powernv-cpufreq module is not automatically loaded by the kernel (even if put in the initramfs).

Would it be possible to have it built-in (rather than as a module) in some time?

As discussed on Ubuntu's kernel-team mailing list, it fails gracefully on non-compatible hardware
(and even on compatible hardware with older, development firmware versions w/out that support, if that happens on your tests)
