Explore power management in the Linux Kernel through this conference talk focusing on converting legacy_pm to dev_pm_ops. Learn about the two methods for drivers to register power management interfaces, understand the limitations of Legacy PM ops, and discover the benefits of dev_pm_ops. Delve into the approach for converting drivers, including class and bus drivers, and the process of obsoleting and removing legacy pm_ops. Gain insights from observations made during the conversion process, and examine the discussion goals and outcomes, including converted class drivers and mmc host platform drivers. This talk, presented by Shuah Khan from Samsung at the Linux Plumbers Conference, provides valuable information for kernel developers and those interested in Linux power management optimization.
