Description:

System suspend is one of the most mature and widely used power management techniques in Linux. At the same time the kernel's system suspend infrastructure is susceptible to inadvertent errors, so major changes in that code are relatively rare and applied with caution. However, that conservative approach has caused system suspend to gradually fall behind with meeting the expectations of modern systems' users. It has turned out recently that it needs to be faster, integrated more tightly with runtime PM, more careful about avoiding unnecessary operations and capable of handling systems with more advanced PM support in hardware in better ways. As a result, several efforts are under way to improve system suspend in Linux and make it even more useful. I will discuss those efforts, describe the improvements that have been achieved already and outline possible directions of future development.
