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 > On the other hand, unless some extra work was done in preventing the > scenario in patch 1/2, I think that can still be discussed.
