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  statscpuinfo_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  statscpuinfo_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  statscpuinfo_cur_freq  cpuinfo_min_freq  related_cpus  scaling_available_governors    scaling_driver    scaling_max_freq  scaling_setspeedrk3588_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:/ $ surk3588_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。
