Improving boot time is always a delicate matter and literature is very rich. Linux based OSes benefit from standard optimization approaches however, Android is still far away from having exciting results especially because most the heavy block happens in user space. Hibernation, suspend-to-disk, is undoubtedly a different perspective to look at improving boot time. When the hibernation mode is entered the system hardware state is copied to non-volatile memory like MMC and all power can be removed by the system. On resume, the system is restored from peripherals to memory in a predetermined way. From this perspective just the very first boot will be a “regular” one and all the subsequents is just a restore operation which can take a few seconds. This session will provide the current state of the kernel development of Hibernation on ARM architectures and our tests on the popular i.MX family of processors including the new i.MX8 which today is one of the most promising SOCs.
