For the RT patchset, add a preempt-rt fragment to the "mainline" fragment directory to make it easier to build automatically without having to go into menuconfig and select the Fully Preemptible Kernel (RT) to be the Preemption Model and to turn of CPU Frequency scaling. It isn't mandatory to turn off CPU_FREQ. However, you get a more predictable latency range.

Hi Andrey,
I'm unsure but can this fragment be added to the config-core-4.1 branch?
Cheers, Anders

LSK versions up until v3.18 had this included because we had a clone of Andrey's configs repo, but starting with LSK v4.1 we dropped the LSK configs and are just using Andrey's tree.

Yes, sure. Done. Kevin's "Acked-by" has also been included.
Thanks, Andrey

Gak. All the other files in this repo end in .conf, not .config and the kernel CI scripts are looking for the .conf suffix too.
Andrey, could you rename in the repo?
Thanks,
Kevin

I've pushed an updated version of the lsk-v4.1-rt-test branch and will see how this turns out after a spin through kernelci.org.
