Armbian can't run fast at rock pi s

#1 
Kernel   version of debian release  is too old to suport my application ,so I try armbian with radxa github public version.But it don't works well.top frequency maybe very low.and I can't read it:

pi@rockpi-s:/sys/devices/system/cpu/cpufreq$ ls
pi@rockpi-s:/sys/devices/system/cpu/cpufreq$

I capture some system boot log,wish someone can help me!

#2 
sudo watch -n 1  cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq

Lets you check current clock but cat around there will get you max in the right directory

Armbian often install cpufrequtils check /etc and edit also.
https://www.thinkwiki.org/wiki/How_to_use_cpufrequtils

Newer RK3308 have a lower clock of 1.2Mhz max I think from mem well just short of 1.2Mhz

#3

Nothing! I think dtb is not loaded correctly.

#4

According to the documentation on the S/H chips, the maximum speed is now 1104MHz.

Close enough as don’t that is @solaris3308 problem.

Look this:

On debian 10 with kernel 4.4 the score of “events per second” is 23XX.I sure cpu-freq of armbian is much lower than it on debian10

By the way,I look at this :
pi@rockpi-s:~$ sudo cat /sys/kernel/debug/opp/opp_summary
cat: /sys/kernel/debug/opp/opp_summary: No such file or directory
Looks like oop part of dtb is loaded.

cpufreq-driver also is not loaded.

The 5.18 kernel has broken cpufreq on the rock-pi-s.
Trouble was in the rk3308-rock-pi-s.dts device tree definitions.
[A couple overclocking CPU rates were incompletely defined]
Here are my sysbench results with cpufreq working again (ondemand governor):
(about a 25% speed improvement)
