Real-time kerel not detected on patched 6.12

Category: General LinuxCNC Questions

@rodw Can you confirm that it's the same with the Raspberry or is that kernel source already patched?

I noticed that the patch only works when VMCORE_INFO=y which gets selected by:
 - CRASH_DUMP [=y] && ARCH_SUPPORTS_CRASH_DUMP [=y] && KEXEC_CORE [=y] 
 - PROC_KCORE [=y] && PROC_FS [=y] && MMU [=y]

Is really necessary for LinuxCNC to check that /sys/kernel/realtime or will checking for "PREEMPT_RT" in uname -v be enough?

No idea if there is a driver for I2C in LinuxCNC, maybe searching on github project page would show if there is anything about it there.
