    Context: PREEMPT_RT is an out-of-tree patch for Linux, which allows to turn it into a real time operating system, kinda like FreeRTOS. This is has a ton of real life application, from low-latency video game servers to firmwares for 3D printers.

        Nope. Firmware for 3D printer is the thing that actually runs on the printer itself. It has to be realtime because you can't have interrupts or some oher things stop your printing for a second...

        Nope. Firmware for 3D printer is the thing that actually runs on the printer itself. It has to be realtime because you can't have interrupts or some oher things stop your printing for a second thus Linux becoming realtime OS could then be used on such things.

        I run Linux on desktop and I 3D print. It's not the smoothest experience, but it works really well.

    I had no idea that there were plans to mainline realtime support. Pretty cool.
