CPU fixed frequency
The cpu of RK3588 is 4 A55+4 A76, divided into 3 groups for separate management, the nodes are:
/sys/devices/system/cpu/cpufreq/policy0:（4 A55：CPU0-3）
affected_cpus cpuinfo_max_freq cpuinfo_transition_latency scaling_available_frequencies scaling_cur_freq scaling_governor scaling_min_freq stats

The above 3 CPUs are independently controlled, the following takes setting CPU6-7 as an example to illustrate how to set the frequency of CPU6-7

The default is the automatic frequency conversion mode: schedutil (if it is restored, it can be set to this mode)
Set manual fixed frequency mode: userspace
rk3588_armsom_w3:/ $ su

rk3588_armsom_w3:/ # cat /sys/devices/system/cpu/cpufreq/policy6/cpuinfo_cur_freq

The other two groups of CPUs are also set in a similar way, just operate the corresponding nodes.

The Power allocator temperature control strategy introduces PID (proportional-integral-derivative) control, and dynamically allocates to each cooling device according to the current temperature
power, when the temperature is low, the power that can be allocated is relatively large, that is, the frequency that can be run is high. As the temperature rises, the power that can be allocated gradually increases.
Gradually decreases, the operable frequency also gradually decreases, so as to reach the limit frequency according to the temperature.
If you want to turn off the temperature control, you need to add this patch

The maximum CPU frequency of RK3588 can reach 2.4G, and the main frequency of RK3588J and RK3588M will be reduced.
The device tree in the kernel is configured with 2256000000, 2304000000, 2352000000 and 2400000000 frequencies. However, the code will choose a suitable maximum frequency in 2.2-2.4G according to the PVTM information of the current master
