Real-time kerel not detected (Orange PI) was created by royka
I've compiled Linux 6.12 with Full real-time enabled, but somehow it's not detected as real-time by LinuxCNC. When I set the priority manually at RT via "sudo htop" and press I, the latency is low so I'm sure that it's compiled correctly.
Perhaps the detection method need to be changed?

Changed the tittle to reflect the Orange PI in use.

It's not only on Orange Pi, also on x86, both mainline Linux so it would be nice if you could set the title back again.

6.12 should have Preempt and it can be actvated with PREEMPT=FULL at GRUB.
Did not test on 6.12, on 6.11 it would ignore the above.

As you can see in the screenshot it's configured with fully preempted. Are you sure that this kernel parameter makes it real-time? Isn't this only to make it low latency when the kernel is configured is dynamic?
