System-level quality of service. Future Some architectures can guarantee QoS on internal interconnects and caches, etc. (what else?) controlled by VM configuration or h/w controls.
Example of current architectures is support for QoS on AXI bus masters and GPU on R-Car.
(work needed to separate future from current architectures. MPEM future for example? Presumably other examples of current architectures be it SoC specific or IP)
– ref armv8 manual. MPEM Memory system resource performance....
Inter-partition protocols for example leveraging VIRTIO. (Partitions = VMs, to/from HV, but also between OSes running bare metal on dedicated core)
