Maintaining a Real Time Stable Kernel
Presenter:Steven Rostedt, VMware Summary: This slides will present what is required to maintain a stable RT tree, such as tools that you can use. What tricks can be done with git to find properly backport patches that are RT specific. It will also cover the current tests that are performed to make sure the released RT stable kernel is fully functional.

CPU Power Saving Methods for Real-time Workloads
Presenter:Ramesh Thomas, Intel Summary: The presentation will give a background of the issues faced by real-time applications when CPU power management is enabled. It will then explain tools, configurations and methods that can be used to tune applications and CPU power management in the kernel to be able to save power without impacting the deterministic latency tolerance requirements.
