Technically yes. But it can't support many hard real-time use cases. For that you need a true RTOS, thought from the ground up for that purpose. Something like VxWorks, QNX, some flavors of L4.
The thing is that even quite old Intel CPUs have good transcoding support with Jellyfin. For people buying used desktops is great. AMDs are a more recent development. Since you're building everything brand new, take your pick. With AMD you could run some light ROCm workloads.
Yet, when Microsoft, Apple and every other proprietary software house do it with permissively licensed code, I don't see anybody complaining.
The declaration of intent by the author is the license. If they don't want commercial redistribution of their work, do like Futo. Otherwise we'll all start taking crazy pills and demand people adhere to an imagined restriction that isn't written anywhere.
I think there's a USB device inside the mobo to handle dumb peripherals. So it would still trigger an interrupt, but it wouldn't make it to the CPU. The USB keyboard controller would handle it and cache the strokes locally until polled by the CPU.
Because there isn't one. OC is deranged.
