virtio_driver

Driver-side implementation of the virtio 1.x PCI transport, shared by Rust virtio drivers, such as virtio-gpu-display.

The library is parked under //src/graphics/display because it is still coupled to display. Once it is cleaned up, it may move to //src/devices.

The crate documentation in src/lib.rs introduces the concepts used in the API.

Testing

fx test virtio-driver-rust-test
