Bug#793185: [linux-sunxi] Re: forwarding a bug: cpufreq missing in debian stable on a cuibeboard
I got lost somewhere in that long thread but I saw cpufreq on cubie* works for someone [0]. It's just a matter of loading two modules. I tried myself on my jessie install (kernel from experimental) and can confirm that: leo@cubetto:~$ sudo modprobe axp20x-regulator leo@cubetto:~$ sudo modprobe cpufreq-dt leo@cubetto:~$ ls /sys/devices/system/cpu/cpu0/cpufreq/ affected_cpus related_cpus scaling_governor cpuinfo_cur_freqscaling_available_frequencies scaling_max_freq cpuinfo_max_freqscaling_available_governorsscaling_min_freq cpuinfo_min_freqscaling_cur_freq scaling_setspeed cpuinfo_transition_latency scaling_driver stats How do I make this change persistent?

Bug#793185: forwarding a bug: cpufreq missing in debian stable on a cuibeboard
Hi there! I've just installed Debian stable on my Cubieboard using their installer. Debian's mainline 3.16 kernel works fine but cpufreq is missing (sunxi 3.4 kernel supports it). I've submitted a bug [0] in the Debian BTS and tried kernel 4.0 and 4.1 from unstable and experimental branches with no success (cpufreq support should be there from linux 4.0 [1]). I'm forwarding that bug here as suggested. Thanks for helping! Leonardo [0] https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=793185 [1] http://linux-sunxi.org/Linux_mainlining_effort#Merged_into_4.0
Bug#793185: linux-image-3.16.0-4-armmp: missing cpufreq on cubieboard (Allwinner A10 sun4i)
I tried comparing dmesg from sunxi kernel (3.4) and experimental (4.1) but I couldn't spot anything relevant. Both are attached as I'm not skilled enough and I might have missed something. 2015-07-22 14:07 GMT+02:00 Ian Campbell : > On Wed, 2015-07-22 at 13:21 +0200, Leonardo Canducci wrote: > > > > Maybe some device-tree issue? > > Perhaps.
