Not me....
But....
I have synced my repo with upstream and they say the pi5 is supported now in the image builder we use.
I am building an image for the Pi5 as we speak.
The kernel built OK but I may have had an error building the root file system. Checking again.
If I have any luck, I will share a file.

if you use the commit we have been using it wont boot, if my experience is anything to go by. I'm trying to build natively with the 6.1.y branch

I have uploaded an image for the Raspberry Pi 5 here:
drive.google.com/drive/folders/1B29ewKVL...0QJGj?usp=drive_link
The RT kernel and the headers are available in the kernel sub folder. You could try installing both with dpkg -i on an ordinary image.
Please let me know how you get on.
Note the Linuxcnc repos are set up in your sources. (I hope)
so
sudo apt update
sudo apt upgrade
should be valid and not break anything.
But there will be nothjing to upgrade unless one of these happens:
1. Debian releases an updated version of Bookworm
2. Debian releases som urgent security patches
3. Linuxcnc doeas an upgrade from version 2.9.1
Please give your feedback I don't have a Pi 5.

Its possible if you accepted the defaults you built a 4b kernel
You have to run menuconfig as it was configured to build a kernel for the 4b/400 with a saved defconfig

I hope it does now. There isn't a later PREEMPT_RT merged into their kernel.if you use the commit we have been using it wont boot, if my experience is anything to go by. I'm trying to build natively with the 6.1.y branch

I used the kernel-builder script referenced earlier, no boot with the commit we've used for the rp4 (non-realtime), finally got it to boot with the 6.1.y branch.
One thing of note in the commit there is no arch/arm64/configs/bcm2712_defconfig but it is there in the 6.1.y branch.

I merged your master branch into the linuxcnc-2.9.1 and updated the kernel hash and patch to 5_6.1.59-rt16.
Kernel gets into gets into a "running /scripts/local/block" loop and the rootfs fails to build.

I tried that image and it does not boot in a rpi5, in fact there are no bcm2712-rpi-5-b.dtb file being generated, so I'd assume that 5_6.1.54-rt15 does not support the rpi5.Cornholio post=285614 userid=35653

Kernel built with latest 6.1.y commit with rt16 patch does boot with previously shared bookwork image.

This is when the 6.61 branch was merged into 6.1.y on Nov 3
This will at least lock in a known position rather than just following the head.
For reference we are looking at the 6.1.y commits here github.com/raspberrypi/linux/commits/rpi-6.1.y
