Description of problem:
On FC24 for ARM, the CPUFREQ seems missing on kernel 4.7.6-200 for ARMV7HL
It was existing in default kernel in image (4.5.5-300)
Version-Release number of selected component (if applicable):
Boot as 4.7.6-300 kernel.
Folder /sys/device/system/cpu/cpufreq is empty.
Image is Fedora 24 server for BananaPi
Can you see if you can work out where it disappeared? Was it there for the 4.6.x kernel series?
Following kernels here https://kojipkgs.fedoraproject.org/packages/kernel/
The 4.6.7-300 doesn't work too.
Trying other one and tell you here asap.
Working on last 4.5.x for FC24 (4.5.7-300).
Not working on first 4.6 for FC24 (4.6.3-300)
So it was lost on 4.6 :(
So there's nothing specific to cpufreq that's changed between those kernel configs. The expected module (cpufreq-dt.ko) is still there. So the question is what else has changed...
I think this should now be fixed with kernel-4.8.4-200.fc24
$ cat /sys/bus/cpu/devices/cpu0/cpufreq/scaling_governor
$ cat /sys/bus/cpu/devices/cpu0/cpufreq/cpuinfo_cur_freq
$ cat /sys/bus/cpu/devices/cpu0/cpufreq/cpuinfo_max_freq
Cannot try my bananapi is not available :(
