[移动开发]高通调试performance mode

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
