Kernel Recipes 2018 - CPU Idle Loop Rework - Rafael J. Wysocki
The CPU idle loop is the piece of code executed by logical CPUs if they have no tasks to run. If the CPU supports idle states allowing it to draw less power while not executing any instructions, the idle loop invokes a CPU idle governor to select the most suitable idle state for the CPU an

Kernel Recipes 2015 - Introduction to Kernel Power Management - by Kevin Hilman
In order to keep up with the complexities of SoCs, the Linux kernel has an ever-growing set of features for power management. For the uninitiated, it can be confusing how each of these features work and even more confusing how they should work together. This talk will be a high-level intro

Kernel Recipes 2017 - Overview of Generic PM Domains (genpd) - Kevin Hilman
The generic PM domains (genpd) framework in the kernel provides a way of grouping devices together that have common power management (PM) operations. It is commonly used to represent hardware power domains (a.k.a power islands) that share a common voltage rail, but can also be used more ge

Embedded Recipes 2019 - RT is about to make it to mainline. Now what?
The PREEMPT_RT (aka real-time patch) started back in 2004. Since then, a lot of it has made it into the kernel. The only part left is the change of turning spinning locks into mutexes, then the merge of the PREEMPT_RT patch will be complete. This is expected to happen no later than the Q1

Kernel Recipes 2022 - The complete story of the in-kernel sloppy GPIO logic analyzer
You know the rules, right? You should not implement a logic analyzer in software because equidistant sampling points cannot be guaranteed. You should also not disable interrupts in your kernel code, and if you really need to, it should be as short as possible. And surely you should not all
