以上3个CPU是独立控制，下面以设置CPU6-7为例说明如何设置CPU6-7的频率
获取当前CPU支持的频点

rk3588_s:/ # cat /sys/devices/system/cpu/cpufreq/policy6/scaling_available_frequencies 408000 600000 816000 1008000 1200000 1416000 1608000 1800000 2016000 2208000 2400000

获取cpu运行的模式

rk3588_s:/ # cat /sys/devices/system/cpu/cpufreq/policy6/scaling_available_governors conservative ondemand userspace powersave performance schedutil

默认是自动变频模式：schedutil（恢复的话设置为该模式即可）
设置手动定频模式：userspace

1|rk3588_s:/ $ su rk3588_s:/ # echo userspace > /sys/devices/system/cpu/cpufreq/policy6/scaling_governor

设置频率为2016000

rk3588_s:/ # echo 2016000 > /sys/devices/system/cpu/cpufreq/policy6/scaling_setspeed

确认是否设置成功

rk3588_s:/ # cat /sys/devices/system/cpu/cpufreq/policy6/cpuinfo_cur_freq 2016000
