查看RK3588 CPU GPU DDR NPU的频率电压表
在设计上面通过ADB命令可以查看机器的频率电压信息：
rk3588_s:/ $ su
rk3588_s:/ # cat /d/opp/opp_summary
device rate(Hz) target(uV) min(uV) max(uV)

CPU定频
RK3588的cpu是4个A55+4个A76，分为3组单独管理，节点分别是：
/sys/devices/system/cpu/cpufreq/policy0:（对应4个A55：CPU0-3）
affected_cpus cpuinfo_max_freq cpuinfo_transition_latency scaling_available_frequencies scaling_cur_freq scaling_governor scaling_min_freq stats
cpuinfo_cur_freq cpuinfo_min_freq related_cpus scaling_available_governors scaling_driver scaling_max_freq scaling_setspeed
/sys/devices/system/cpu/cpufreq/policy4:(对应2个A76：CPU4-5)
affected_cpus cpuinfo_max_freq cpuinfo_transition_latency scaling_available_frequencies scaling_cur_freq scaling_governor scaling_min_freq stats
cpuinfo_cur_freq cpuinfo_min_freq related_cpus scaling_available_governors scaling_driver scaling_max_freq scaling_setspeed
/sys/devices/system/cpu/cpufreq/policy6:(对应2个A76：CPU6-7)
affected_cpus cpuinfo_max_freq cpuinfo_transition_latency scaling_available_frequencies scaling_cur_freq scaling_governor scaling_min_freq stats
cpuinfo_cur_freq cpuinfo_min_freq related_cpus scaling_available_governors scaling_driver scaling_max_freq scaling_setspeed
rk3588_s:/ #
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
其他两组CPU也是类似的方式进行设置，操作对应的节点即可。
