Adding functionality to bootstat --record_boot_complete and
--record_boot_reason to initialize sys.boot.reason, the canonical
system boot reason.
Filter out ro.boot.bootreason oem noise into sys.boot.reason. Add
heuristics to determine what the boot reason is, when otherwise would
be defaulting to the blunt and relatively devoid of detail catch-all
reboot reasons ("reboot", "shutdown", "cold", "warm", "hard").
boot_reason_test.sh is also a compliance test.
Test: boot_reason_test.sh all
Bug: 63736262

# sys.logbootcomplete is a signal to enable the bootstat logging mechanism.
|
|
# This signaling is necessary to prevent logging boot metrics after a runtime
|
|
# restart (e.g., adb shell stop && adb shell start). /proc/uptime is not reset
|
|
# during a runtime restart, which leads to false boot time metrics being reported.
|
|
#
|
|
# The 'on boot' event occurs once per hard boot (device power on), which
|
|
# switches the flag on. If the device performs a runtime restart, the flag is
|
|
# switched off and cannot be switched on until the device hard boots again.

# Enable bootstat logging on boot.
