Extend aarch64 support in rust-vmm/vmm-reference
Summary: Flesh out aarch64 (ARM) support in vmm-reference to make its features comparable to x86_64
The vmm-reference is a reference implementation of a Rust VMM based on rust-vmm crates. This is currently used for testing the integration of rust-vmm components, with plans of extending it such that it becomes a starting point for custom Rust VMMs.
The vmm-reference currently has support for x86_64 and proof-of-concept level support for aarch64. On aarch64, it just supports booting a dummy VM with no devices, while on x86_64 it has support for the virtio-net and virtio-blk devices. The purpose of this project is to extend the existing functionality getting it closer to what is already available on x86_64, and consume the readily available crates (for example vm-allocator) that would make the integration easier.
- Set up interrupt controller.
- Add a real-time clock device.
- Add a serial port.
- Add flattened device tree (FDT) so guest has a machine description.
