Some links for you:


The Real-Time Wiki at the Linux Foundation:

https://wiki.linuxfoundation.org/realtime/


The latest development RT patch series for 6.7:

https://cdn.kernel.org/pub/linux/kernel/projects/rt/6.7/patches-6.7-rt6.tar.xz


RT git (branch linux-6.7.y-rt-rebase is probably what you want):

https://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git
