This is a companion discussion topic for the original entry at https://copr.fedorainfracloud.org/coprs/rmnscnce/kernel-xanmod/

I was just looking into trying to compile the RT on Fedora 33. Is the lack of RT here temporary and just needs work, or are there some specific issues with it?

Is the lack of RT here temporary and just needs work

Totally temporary. I will package RT variants as soon as the rt-edge branch on upstream got rebased to 5.11.y. Using “oldstable” (5.10.y is considered “oldstable” even though it is LTS) kernels is not the way of Fedora Linux, I believe.

Also I currently have a lot of stuff to do IRL so adding a new package is not in my roll right now. (Don’t worry, upstream is still and will be getting merged)

RT is in the build process right now. It hopefully will be ready in the next 2 hours or so

consider update the dependencies/requirements to follow fedora upstream?
