Hi.
I've been trying to adjust the frequency but never seen
/sys/devices/system/cpu/cpufreq/policy0/scaling_cur_freq say anything other than 600000
even with 2 cpu intensive processes running.
I have 4.19.13-300.fc29.aarch64
It seems that despite
# cat scaling_available_frequencies
600000 900000 1200000 1400000
scaling_max_freq is stuck on 600000
With the scaling_governor set to performance or ondemand, I don't seem able to adjust
the scaling_max_freq, so the cpu is always stuck at 600MHz,
[root@sam-pi policy0]# echo 1400000 > scaling_max_freq
[root@sam-pi policy0]# cat scaling_max_freq
600000
with govener set to userspace I am also unable to make changes
[root@sam-pi policy0]# echo 900000 > scaling_setspeed
[root@sam-pi policy0]# cat scaling_setspeed
600000
Is there anything more I need to do?
do you have the entries "enable_uart" or "core_freq" in your
config.txt?
Try to uncomment them.
Best regards
Stefan
