Monsters, Ghosts, and Bugs: How to Choose a Kernel

Explore the intricacies of kernel selection in this informative conference talk. Delve into the various options available for kernel choices, ranging from well-tested enterprise kernels to forward-looking community distributions and self-compiled versions. Understand the impact of kernel selection on system performance and learn about the trade-offs between features, security, and ease of management. Gain insights into the upstream kernel release process, including merge windows and the challenges faced by maintainers. Discover the balance between stability and new features, and the potential risks of unexpected bugs. Examine the concept of "Frankenkernels" and the limitations of stable kernel reviews. Learn from Android's success story in the embedded space and understand the importance of community engagement in open-source development. Explore the daily tasks of kernel maintainers and the effort involved in backporting. Conclude by evaluating your specific kernel needs and making informed decisions for your system.

Intro
What kernel is running on your system?
Why are you running that kernel?
Monsters, Ghosts, and Bugs
The Upstream Kernel Release Process
Merge Window
Busy for maintainers
When will my patch go in?
What exactly is going into stable updates?
Stability vs. Features
Features! Hardware! Awesome!
Unexpected bugs (less awesome)
"Frankenkernel" (Scary monster!)
Actually, Frankenstein was the name of the creator
Stable kernels test the limits of review
Embedded
Android: success story
Learn how to engage the community
Open Source means you can do this!
What do kernel maintainers do all day?
Backports are effort
Distributions are not perfect
Wrapping up
What do you want your kernel to do?
Thank you! (come see me at the Red Hat booth)
