Sufficient Temporal Independence and Improved Interrupt Latencies in a Real-Time Hypervisor
Matthias Beckert, Moritz Neukirchner, Rolf Ernst, Stefan M. Petters · 2014
Virtualization techniques for hard real-time systems typically employ TDMA scheduling to achieve temporal isolation among partitions. The processing of user-level interrupt handlers is only performed within appropriate time slots, thus significantly increasing interrupt latencies.
