With the image of armbian kernel 6.8.0-RC1-edge, without real time but with isolcpus = 5.7. Something better in Servo Thread behaves, I have a Orange Pi 5.

No, this is much worse than the first picture, see the colored columns on both sides of the graph.
Use --show at the end of the latency-histogram line to show those excursions.

Thanks Royka for the image of the kernel.

I have installed the kernel in Armbian Debian Bookworm, the results are magnificent.

Is SPI working at proper speed on Orange Pi 5 for real time use? (Raspberry Pi 5 SPI currently has issues with slow speeds / access making it not suitable for real time functions I believe)

With royka kernel 5.10.160-rt89+-5 works very well, but I sometimes use internet with opi5 and where I am there is no internet, I connect with android mobile phone via portable hotspot - internet sharing via USB.
But with royka's rt kernel it doesn't detect the connection, before installing the kernel it detects the connection.
I guess it is some kernel option that is disabled.

Does anyone have any idea of what option to enable in the kernel of the thousands that there are.

That's strange, maybe you can try this kernel on another image:

I'm using this kernel with the Debian Bookworm Image from the site of Orange Pi and HW acceleration works, although while watching YouTube videos the latency increases a bit, but not so much as yours for sure.

I tried to install linuxcnc with the image from the orange pi Debian Bookworm site, but linuxcnc is not in the Chinese repositories, I download the debs files from the linuxcnc site and there are many unfulfilled dependencies.
The orange pi site image works pwm, the armbian image does not work pwm.

@angelnu Here you can find the kernel options to enable android sharing.
wiki.gentoo.org/wiki/Android_USB_tethering

This kernel is with Android and iOS USB tethering enabled:
drive.google.com/file/d/1KS7IkLzMxAQJIOT...m4v/view?usp=sharing

You can edit the apt sources "/etc/apt/sources.list" to:

deb http://deb.debian.org/debian bookworm main contrib non-free non-free-firmware

deb http://deb.debian.org/debian bookworm-updates main contrib non-free non-free-firmware

deb http://repo.huaweicloud.com/debian bookworm-backports main contrib non-free non-free-firmware

deb http://linuxcnc.org bookworm base 2.9-uspace

Many thanks to Royka for his help, it seems to work quite well. Let's see if I learn to compile the kernel.
I have not been able to compile the kernel in real time.

To compile the rt kernel on the OPi5:

git clone https://github.com/orangepi-xunlong/linux-orangepi.git -b orange-pi-5.10-rk35xx-rt
cd linux-orangepi
cp /boot/config-5.10.160-rt89+ ./.config
make menuconfig #Here you can make your changes
make -j$(nproc)
sudo make modules_install
sudo make install

Here LinuxCNC 2.10 build from master today:

Orange pi 5 can work with the onboard header I/O with linuxcnc ?
