Abstract
Improving system boot time has become one of the most important issues in the system software arena. As Linux is widely used in the embedded system environment, extensive research has been conducted in order to mitigate Linux boot time delay. In this respect, this paper mainly focuses on the Hibernation-based boot mechanism, which is the boot mechanism based on Hibernation, as an alternative to the conventional boot sequence. The contributions of this work are as follows. First, we implement the Hibernation-based boot mechanism on a real embedded Linux system and describe the implementation details. Second, we observe the Hibernation-based boot procedures so that we can investigate the possibility whether the boot mechanism has room for improvement in terms of the boot time. Through the in-depth observation and analysis based on the real implementation, we anticipate that the Hibernation-based boot mechanism which adopts various optimization methods can provide maximum of 3.1 times faster booting performance compared to the conventional way.
