    Of the many great features/changes for Linux 4.17, one of the most exciting to us is the idle power efficiency and performance-per-Watt improvements on some systems thanks to a rework to the kernel's idle loop handling. Rafael Wysocki and Thomas Ilsche as two of the developers working on this big code change presented on their work today for this CPU idle loop ordering problem and its resolution. Taking place yesterday through tomorrow is the second annual OSPM Summit in Pisa, Italy. The OSPM summit is about power management and scheduling within the Linux kernel. Today is when Wysocki and Ilsche took the stage to talk about this CPU idle code situation.
