And what results on exynos3250 ? I had to change some of the ways for synchronization two cores (boot vector behaves differently) so actually the driver is different except the general idea. As for the results (on dual-core Exynos3250) - the mode (AFTR+CPU1 off) consumes about 5% less energy than idle-WFI state. I expect there will be much more savings in deeper mode (called here W-AFTR).
