Running 6.12.19 SMP PREEMPT kernel, seeking a path to run PREEMPT-RT (full real-time) kernel

[Gautam Thaker]

In my H96 TV box I have been running Armbian for over an year. Works great. Today I did a fresh install of:

Armbian_community_25.5.0-trunk.256_Rk3318-box_bookworm_current_6.12.19_minimal.img.xz

uname -a shows:

rk3318-box> uname -a
Linux rk3318-box 6.12.19-current-rockchip64 #2 SMP PREEMPT Thu Mar 13 12:02:20 UTC 2025 aarch64 GNU/Linux

It is my understanding that Linux 6.12+ kernel already have all the real-time patches in the mainline kernel sources. All one needs to do is to 

1. rebuild the kernel after configuring for FULL PREEMPT-RT  support

or (if kernel already built with this configured)
1a. reboot after providing to 'grub'  a boot option "preempt=full"

If any one has had experience running the full PREEMPT-RT kernel on rk3318 (or any Armbian box)?  

What are the best steps to get and natively build a new kernel for 6.12.19 on my rk3318 box (only show 27 Gb free though, may not be enough.)
