Description

After running adb root adb shell simpleperf boot-record --enable "-a -g --duration 10 --exclude-perf""' adb reboot

I can not get the profile data under /data/simpleperf_boot_data. Look likes simpleperf didn't work in booting.

On which android version are you using the command? The function needs support of init script in https://cs.android.com/android/platform/superproject/+/master:system/extras/simpleperf/simpleperf.rc, which doesn't exist before android T. To help debug, can you upload result of getprop persist.simpleperf.boot_record and logcat | grep simpleperf before and after reboot?
