I still don’t quite get how the cpu knows what is low priority or background. Or is that steered at OS level a bit like cpu pinning ?

Right so how does the scheduler know what’s low priority?

I thought this was actually a good question, so I have trued to look it up. If I understand correctly the CPU tells the scheduler! I could not find exactly how though, maybe an MSR?
