Rockchip Android平台常用调试命令汇总

查看帧率信息

通过串口或者adb 输入如下命令

setprop debug.sf.fps 1
logcat | grep mFps
1
2

滑动界面后可以在logcat中可以输出当前系统显示的帧率信息

rk3588_s:/ $ setprop debug.sf.fps 1
rk3588_s:/ $ logcat | grep mFps

查看显示图层信息

cat /d/dri/0/summary
1

通过该命令可以查看显示分分辨率和使用图层信息

130|rk3588_s:/ $ cat /d/dri/0/summary

手动触发内核产生panic

echo c > /proc/sysrq-trigger
1

通过命令设置Android系统不进入二级休眠

echo "PowerManagerService.noSuspend" > /sys/power/wake_lock
1

开关CPU的task boost的功能

RK356x cpu增加了，task boost的功能：（比如后台有任务切换都会boost），可以通过如下命令进行开关

• 关闭

echo 0 > /proc/sys/kernel/sched_performance_bias
1

• 开启

echo 1 > /proc/sys/kernel/sched_performance_bias
1

通过命令控制pm_domains和clk常开

通过adb 敲命令的方式：

• pm_domains常开

echo 1 > /sys/module/pm_domains/parameters/always_on
1

• clk常开

echo 1 > /sys/module/clk_gate/parameters/always_on
1

通过命令开关cpu

• 关闭某个cpu核

echo 0 > sys/devices/system/cpu/cpux/online
1

• 打开某个cpu核

echo 1 > sys/devices/system/cpu/cpux/online
1

强制让系统进入二级休眠

echo mem > sys/power/state

设置默认使用nuplayer播放视频

 setprop use_nuplayer true

Android 手动旋转屏幕

rk3588_s:/ # settings put system accelerometer_rotation 0
rk3588_s:/ # content insert --uri content://settings/system --bind name:s:user_rotation --bind value:i:0   //旋转0度
rk3588_s:/ # content insert --uri content://settings/system --bind name:s:user_rotation --bind value:i:1  //旋转90度
rk3588_s:/ # content insert --uri content://settings/system --bind name:s:user_rotation --bind value:i:1   //旋转180度                                                                                     
rk3588_s:/ # content insert --uri content://settings/system --bind name:s:user_rotation --bind value:i:3  //旋转270度
