Hypervisor-less Virtio: Assembling Multi-OS Systems Using Standards-based Pro...
summary
Claims a working hypervisor-less virtio prototype that uses standard virtio over MMIO and pre-shared memory to connect Linux on A53 cores with Zephyr on an R5 core, implemented with a user-space physical machine monitor (kvmtool-based back end), Zephyr front ends and pre-shared memory bounce buffers or driver shims. Current Zephyr support covers network console and entropy, target QEMU A53 and Xilinx ZC102, lateral MMIO gives good performance, shared-memory needs are small but per-device notifications and some backends still require updates.
