How to get initial log from SSC(获取sensor初始化时的log信息)

Below method is about how to get initial log from SSC:
 HAL and ADSP re-start
a.    adb shell stop sensors
b.    adb shell "echo 'related' > /sys/bus/msm_subsys/devices/subsys0/restart_level"
c.    adb shell "echo 'restart' > /sys/kernel/debug/msm_subsys/adsp"
d.    adb shell start sensors
Since both ADSP and HAL restart, it is able to see the early logs such as driver init logs .
