RK3588 频率调校

一、频率查看

# CPU
cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq
# GPU
cat /sys/class/devfreq/fb000000.gpu/cur_freq
# NPU
cat /sys/class/devfreq/fdab0000.npu/cur_freq
# DDR
cat /sys/class/devfreq/dmc/cur_freq

二、频率电压表

策略如下：

interactive：根据 CPU 负载动态调频调压；
conservative：保守策略，逐级调整频率和电压；
ondemand：根据 CPU 负载动态调频调压，⽐ interactive 策略反应慢；
userspace：⽤⼾⾃⼰设置电压和频率，系统不会⾃动调整；
powersave：功耗优先，始终将频率设置在最低值；
performance：性能优先，始终将频率设置为最⾼值；
