黑屏分析

首先,分析各进程状态

adb shell ps |grep -i surfaceflinger
adb shell ps |grep -i system_server

都正常的存在

产生system_server btraces文件

adb shell kill -3 913
adb pull /data/anr/

trace_00
结果正常

产生system_server btraces文件

adb shell debuggerd -b 385 |tee surfaceflinger_385_05.log
for i in {1..100}; do adb shell debuggerd -b 385 >  surfaceflinger_385_$i.log;sleep 1;done

用对比工具做对比发现调用堆栈,内容基本不变,无论做什么操作.看似正常.

查看binder状态

adb pull /sys/kernel/debug/binder/

下面是感觉不太正常的 pid

关注一开始,没有注意到的systemui

其他很多应用由和sysetmui一样的现象,先不做分析

kill system_server 看能否恢复

adb shell kill -9 913 (system_server)

观察到黑屏现象,还继续存在.
说明问题出在下层.

adb shell cat /sys/class/graphics/fb0/msm_fb_panel_info > msm_fb_panel_info_02.log
adb shell cat /sys/class/leds/lcd-backlight/brightness

最后发现是QCOM 图形库的问题

更新SBA搞定.
