2. 获取当前CPU支持的频点
cat /sys/devices/system/cpu/cpufreq/policy6/scaling_available_frequencies 408000 600000 816000 1008000 1200000 1416000 1608000 1800000 2016000 2208000 2304000
3. 获取cpu运行的模式
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）。
4. 设置手动定频模式：userspace
echo userspace > /sys/devices/system/cpu/cpufreq/policy6/scaling_governor
5. 设置频率为2016000
echo 2016000 > /sys/devices/system/cpu/cpufreq/policy6/scaling_setspeed
确认是否设置成功
cat /sys/devices/system/cpu/cpufreq/policy6/cpuinfo_cur_freq 2016000
二．GPU定频
1. GPU的节点路径
ls /sys/class/devfreq/fb000000.gpu/ available_frequencies cur_freq governor max_freq name power target_freq trans_stat available_governors device load min_freq polling_interval subsystem timer uevent
2. 获取GPU支持的频点

3. 获取GPU运行的模式
cat /sys/class/devfreq/fb000000.gpu/available_governors userspace powersave performance simple_ondemand 默认是自动变频模式：simple_ondemand（恢复的话设置为该模式即可）。
4. 设置手动定频模式：userspace
echo userspace > /sys/class/devfreq/fb000000.gpu/governor
5. 设置频率为1000000000
echo 1000000000 > /sys/class/devfreq/fb000000.gpu/userspace/set_freq cat /sys/class/devfreq/fb000000.gpu/cur_freq
6. 查看GPU的负载
cat /sys/class/devfreq/fb000000.gpu/load 0@1000000000Hz
三．NPU定频
1. NPU的节点路径
ls /sys/class/devfreq/fdab0000.npu/ available_frequencies device max_freq polling_interval target_freq uevent available_governors governor min_freq power timer userspace cur_freq load name subsystem trans_stat
2. 获取NPU支持的频点
cat /sys/class/devfreq/fdab0000.npu/available_frequencies 300000000 400000000 500000000 600000000 700000000 800000000 900000000 1000000000
3. 获取NPU运行的模式
cat /sys/class/devfreq/fdab0000.npu/available_governors userspace powersave performance simple_ondemand 默认是自动变频模式：simple_ondemand（恢复的话设置为该模式即可）。
4. 设置手动定频模式：userspace
echo userspace > /sys/class/devfreq/fdab0000.npu/governor
5. 设置频率为1000000000
echo 1000000000 > /sys/class/devfreq/fdab0000.npu/userspace/set_freq cat /sys/class/devfreq/fdab0000.npu/cur_freq
6. 查看NPU的负载
cat /sys/kernel/debug/rknpu/load NPU load: Core0: 0%, Core1: 0%, Core2: 0%
四．RK3588 CPU GPU NPU 温度监控
CPU利用率95%以上时的CPU温升情况，记录cpu各个核的温度，主要针对一下的cpu
RK3588的芯片有7路TS-ADC分别对应：芯片中心位置、A76_0/1、A76_2/3、DSU 、 A55_0/1/2/3、PD_CENTER、 NPU、GPU。
（1）芯片中心位置温度：
（2）CPU大核A76_0/1 即CPU4和CPU5的温度：
（3）CPU大核A76_2/3 即CPU6和CPU7的温度：
（4）CPU小核A55_0/12/3 即CPU0、CPU1、CPU2、CPU3的温度
（5）PD_CENTER的温度：
（6）GPU的温度
（7) NPU的温度
可先运行cpuburn，指定压测核数：
cpuburn -n=4
然后执行下面的附件脚本，每十分钟记录一次，记录24小时，一共24*6=144次。
#!/bin/bash if [ -f /tmp/cpu_temper.log ];then rm -rf /tmp/cpu_temper.log fi for i in {1..144}do echo "$(date +%Y-%m-%d %H:%M:%S)" >> /tmp/cpu_temper.log soc_thermal=`cat /sys/class/thermal/thermal_zone0/temp` soc_thermal_interger=${soc_thermal:0:2} soc_thermal_decimal=${soc_thermal:2:3} soc_thermal_float="soc_thermal="${soc_thermal_interger}"."${soc_thermal_decimal} CPU_A76_01=`cat /sys/class/thermal/thermal_zone1/temp` CPU_A76_01_interger=${CPU_A76_01:0:2} CPU_A76_01_decimal=${CPU_A76_01:2:3} CPU_A76_01_float="CPU_A76_01="${CPU_A76_01_interger}"."${CPU_A76_01_decimal} CPU_A76_23=`cat /sys/class/thermal/thermal_zone2/temp` CPU_A76_23_interger=${CPU_A76_23:0:2} CPU_A76_23_decimal=${CPU_A76_23:2:3} CPU_A76_23_float="CPU_A76_23="${CPU_A76_23_interger}"."${CPU_A76_23_decimal} CPU_A55_0123=`cat /sys/class/thermal/thermal_zone3/temp` CPU_A55_0123_interger=${CPU_A55_0123:0:2} CPU_A55_0123_decimal=${CPU_A55_0123:2:3} CPU_A55_0123_float="CPU_A55_0123="${CPU_A55_0123_interger}"."${CPU_A55_0123_decimal} PD_CENTER=`cat /sys/class/thermal/thermal_zone4/temp` PD_CENTER_interger=${PD_CENTER:0:2} PD_CENTER_decimal=${PD_CENTER:2:3} PD_CENTER_float="PD_CENTER="${PD_CENTER_interger}"."${PD_CENTER_decimal} GPU=`cat /sys/class/thermal/thermal_zone5/temp` GPU_interger=${GPU:0:2} GPU_decimal=${GPU:2:3} GPU_float="GPU="${GPU_interger}"."${GPU_decimal} NPU=`cat /sys/class/thermal/thermal_zone6/temp` NPU_interger=${NPU:0:2} NPU_decimal=${NPU:2:3} NPU_float="NPU="${NPU_interger}"."${NPU_decimal} line=${soc_thermal_float}" "${CPU_A76_01_float}" "${CPU_A76_23_float}" "${CPU_A55_0123_float}" "${PD_CENTER_float}" "${GPU_float}" "${NPU_float} echo $line >> /tmp/cpu_temper.log sync sleep 600s done
