Embedded devices must accommodate opposite requirements: high performance, low latency and low power consumption. Krzysztof Kozlowski will describe features of Linux kernel allowing reducing the power consumption on mobile devices (smartphones, tablets, wearables) without hurting the performance or latency. He will show what kernel configuration options are important, in the field of reduced power consumption, when preparing the kernel for ARM embedded devices. Although the talk will focus on Samsung's Exynos System-on-Chip family, presented ideas can be reused on other ARM embedded devices. Krzysztof will also show how certain features of SoCs match with kernel power management.
