It'd be interesting to see a setup where a Linux-capable SoC would run the Arduino application on a isolated CPU core with no interrupts handled, so you'd still have real-time guarantee for the Arduino app

It runs the Arduino app on a separate mcu stm32l4 I think. So you have the realtime as well, but what you describe is already possible with the pi and asymmetric multiprocessing using openamp and zephyr.

I remember reading about this in some blogs so here is one I found that describes just that: https://telmomoya.blogspot.com/2016/10/asymmetric-multi-proc...

Microchip PolarFire boards (and PIC64 chips, which is basically just the CPU part of PolarFire without the FPGA fabric) can do that with asymmetric multiprocessing: https://www.microchip.com/en-us/products/fpgas-and-plds/syst...
