15.RK3588最高运行性能配置

1.查询npu版本

root@ATK-DLRK3588:cat /sys/kernel/debug/rknpu/version
RKNPU driver: v0.9.8

2.查询npu的负载

root@ATK-DLRK3588:cat /sys/kernel/debug/rknpu/load
NPU load:  Core0:  0%, Core1:  0%, Core2:  0%,

3.显示或者设置NPU、CPU、DDR运行频率

3.1设置方法

./scaling_frequency.sh -h
./scaling_frequency.sh: illegal option -- h
USAGE: ./scaling_frequency.sh -c {chip_name} [-h]
  -c:  chip_name, such as rv1126 / rk3588
  -h:  Help

3.2 RK3588 一键拉满全硬件频率

./scaling_frequency.sh -c rk3588

执行后脚本自动完成：

  1. CPU 小核 A55 (0-3)、大核 A76 (4-7) 全部切换userspace，设到最高频
  2. NPU 切换 userspace，锁定满频
  3. DDR 内存控制器锁定最高带宽频点
  4. 自动读取当前频率，打印Setting Success校验结果

3.3 RK3588 脚本默认频点（单位 KHz）

脚本内置 RK3588 预设：

  • A55 小核：2016000 (2.016GHz)
  • A76 大核：2304000 (2.304GHz)
  • NPU：1000000000 (1GHz)
  • DDR：2112000000 (2112MHz)

3.4 验证 CPU 是否定频成功

#查看小核当前频率
cat /sys/devices/system/cpu/cpufreq/policy0/cpuinfo_cur_freq

#查看大核当前频率
cat /sys/devices/system/cpu/cpufreq/policy6/cpuinfo_cur_freq

#确认调频策略为userspace
cat /sys/devices/system/cpu/cpufreq/policy0/scaling_governor

3.5 验证 NPU 频率

cat /sys/class/devfreq/fdab0000.npu/cur_freq

3.6 验证 DDR 频率

cat /sys/class/devfreq/dmc/cur_freq

3.7 恢复系统自动变频

脚本仅设置手动定频，重启失效；

不重启手动恢复自动调度：

#CPU恢复动态调频(interactive/ondemand)
echo interactive | sudo tee /sys/devices/system/cpu/cpufreq/policy*/scaling_governor
#NPU恢复自动变频
echo dmc_ondemand | sudo tee /sys/class/devfreq/fdab0000.npu/governor
#DDR恢复自动变频
echo dmc_ondemand | sudo tee /sys/class/devfreq/dmc/governor
