This information is captured in a specific format by this driver by mapping a structure to the IMEM memory region and then accessing the members of the structure to print the information. This information is useful in verifying if the existing boot KPIs have regressed or not. A sample log in SM8450(waipio) device is as follows:- KPI: Pre ABL Time = 3s KPI: ABL Time = 14s KPI: Kernel MPM timestamp = 890206 The Module Power Manager(MPM) sleep counter starts ticking at the PBL stage and the timestamp generated by the sleep counter is logged by the Qualcomm proprietary bootloader(ABL) at two points-> First when it starts execution which is logged here as "Pre ABL Time" and the second when it is about to load the kernel logged as "ABL Time". Both are logged in the unit of seconds. The current kernel timestamp is printed by the boot_stats driver as well.
