Apple Silicon machines have no TrustZone, SMM, or anything else to steal control away from the main CPU cores. They also have tricks like being able to direct low-priority IRQs away from CPUs running RT tasks, which we might want to figure out how to support on Linux. The CPU frequency switching latencies are also lower than x86 machines as far as I can tell, and the stalls on switching shorter too. I am very much looking forward to testing out RT on them and seeing how stable I can get low latency audio, compared to typical Intel boxes which are... not great.
