Android中CPU頻率檢視和修改
阿新 • • 發佈：2019-01-06
adb shell "echo 0 > /proc/hps/enabled" (關閉cpu hotplug)
adb shell "echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor" (固定最高頻)
echo 1 > /sys/devices/system/cpu/cpuX/online
X表示(0~3，不同平臺CPU core 數是不一樣的)
例：6735平臺
[email protected]:/ # echo 1 >sys/devices/system/cpu/cpu1/online
echo 1 >sys/devices/system/cpu/cpu1/online
[email protected]:/ # echo 1 >sys/devices/system/cpu/cpu2/online
echo 1 >sys/devices/system/cpu/cpu2/online
[email protected]:/ # echo 1 >sys/devices/system/cpu/cpu3/online
echo 1 >sys/devices/system/cpu/cpu3/online
6、設定頻率(可以先cat 出來當前的頻率有哪些)

[0] = { .cpufreq_khz = 1300000, .cpufreq_volt = 113750, .cpufreq_volt_org = 1250
