Good news, thank you.
I did try the 6.11 with RT on this PC and it failed to load, need more time to test on more hardware, soon!

You still need to set the PREEMPT_RT flag and build the Linux kernel. its not RT by default.Linux is now RTOS. It took 20 years but they finally succeeded !

6.11 shows SMP PREEMPT_DYNAMIC out of the box, did not test LinuxCNC yet.

Preempt-dynamic is not preempt-rt though:

PREEMPT_RT Real time OS is supported natively from Kernel 6.12 and on so not 6.11 (which will require applying the RT patches) before setting the Preempt RT switch and building.6.11 shows SMP PREEMPT_DYNAMIC out of the box, did not test LinuxCNC yet.

I'll be hosting a heavily optimized AMD64 Gentoo build for LinuxCNC and I'll be updating my interactive Gentoo installer too, it'll have the 6.12 PREEMPT_RT kernel, XFCE 4.20 pre-release and LXQt 2.1.
Installer works very well, removes all the hassle from building sources, works with LinuxCNC out of the box (just have to emerge it) and the installer works faster than Ubuntu and Debian installers. It's just out-of-date at the moment.
edit: Currently having serious issues with lxqt-panel (the fricken task bar) so it may just have XFCE instead.
edit2: Problems solved, LXQt will be available in this build too.
