android debug command commonly with qcom chip
- adb shell settings put system screen_off_timeout 3600000 // keep display on
- grover:/ # cat /d/clk/enabled_clocks > /data/CLK_dump.txt // dump enabled clocks
- $ mount -t debugfs nodev /sys/kernel/debug // mount debug fs
- $ echo 1 > /sys/kernel/debug/clk/gcc_blsp1_qup2_spi_apps_clk/enable // enable/disable module specific clock
- $ echo 10000000 > /sys/kernel/debug/clk/gcc_blsp1_qup2_spi_apps_clk/rate // set clock rate
- $ cat /sys/kernel/debug/clk/gcc_blsp1_qup2_spi_apps_clk/measure // measure clock
- surfaceflinger -> layer RGB565

- Eanble performance mode
Try enable performance mode. You can run the following command,
adb root
adb shell stop mpdecision
adb shell stop thermal-engine
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 performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor”
adb shell “echo performance > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor”
adb shell “echo performance > /sys/devices/system/cpu/cpu2/cpufreq/scaling_governor”
adb shell “echo performance > /sys/devices/system/cpu/cpu3/cpufreq/scaling_governor”
echo “gpu perf mode”
adb shell “echo 1 > /sys/class/kgsl/kgsl-3d0/force_clk_on”
adb shell “echo 10000000 > /sys/class/kgsl/kgsl-3d0/idle_timer”
adb shell “echo performance > /sys/class/kgsl/kgsl-3d0/devfreq/governor”
adb shell stop
adb shell start
dump layer of display
adb root
adb remount
adb shell setenforce 0
adb shell setprop debug.sf.dump.enable true
adb shell setprop debug.sf.dump.primary true
adb shell stop
adb shell start
setprop debug.sf.dump.png 20disable hwcomposer
Let me support you. Maybe it is a display issue.
Pls try :
adb root
adb shell service call SurfaceFlinger 1008 i32 1
then observe if your issue is disappeared.
frameworks/native/services/surfaceflinger/SurfaceFlinger.cpp
3214 case 1008: // toggle use of hw composer
3215 n = data.readInt32();
3216 mDebugDisableHWC = n ? 1 : 0;
mDebugDisableHWC = n ? 1 : 0;
3217 invalidateHwcGeometry();
3218 repaintEverything();
3219 return NO_ERROR;
- surfaceflinger dump
// disable hwc
