CPU perf mode:
adb shell "echo 1 > /sys/devices/system/cpu/cpu0/online"
adb shell "echo 1 > /sys/devices/system/cpu/cpu1/online"
adb shell "echo 1 > /sys/devices/system/cpu/cpu2/online"
adb shell "echo 1 > /sys/devices/system/cpu/cpu3/online"
adb shell "echo 4 > /sys/devices/system/cpu/cpu0/core_ctl/min_cpus"
adb shell "echo Y > /sys/module/lpm_levels/parameters/sleep_disabled"
adb shell "echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor"
DDR perf mode:
echo performance > /sys/class/devfreq/soc\:qcom,cpu-cpu-ddr-bw/governor
echo performance > /sys/class/devfreq/soc\:qcom,cpu0-cpu-ddr-latfloor/governor
echo performance > /sys/class/devfreq/soc\:qcom,gpubw/governor
GPU Perf mode:
adb root
adb remount
adb shell setenforce 0
adb shell "echo 1 > /sys/class/kgsl/kgsl-3d0/force_rail_on"
adb shell "echo 1 > /sys/class/kgsl/kgsl-3d0/force_clk_on"
adb shell "echo 1 > /sys/class/kgsl/kgsl-3d0/force_bus_on"
adb shell "echo 10000000 > /sys/class/kgsl/kgsl-3d0/idle_timer"
adb shell "echo 0 > /sys/class/kgsl/kgsl-3d0/min_pwrlevel"
adb shell "echo performance > /sys/class/kgsl/kgsl-3d0/devfreq/governor"
adb shell "echo XXXXXXX > /sys/class/kgsl/kgsl-3d0/gpuclk"
adb shell "echo XXXXXXX> /sys/class/kgsl/kgsl-3d0/devfreq/min_freq"
adb shell "echo XXXXXXX> /sys/class/kgsl/kgsl-3d0/devfreq/max_freq"
Where XXXXXXX is maximum available GPU frequency on device ：adb shell cat /sys/class/kgsl/kgsl-3d0/devfreq/available_frequencies
add below command as well before doing the cpu/ddr/gpu perfmode.
below command will stop the perfhal which will disable the perflocks to make sure that devices will run in the full perf mode during the test .
"adb shell stop perf-hal-2-2"
关闭logd
adb shell stop logd
