Crate arcbox_virtio_core 

arcbox-virtio-core

Foundational types and traits shared by every ArcBox VirtIO device crate. Lives at the bottom of the dependency graph so each per-device crate (arcbox-virtio-net, arcbox-virtio-block, …) and the umbrella arcbox-virtio crate can pull from one place without circular references.

Contents:

• VirtioDevice: the device-implementation trait.
• DeviceCtx: shared guest-memory + IRQ-trigger context that each device holds at runtime.
• QueueConfig: per-virtqueue configuration snapshot built by the VMM from MMIO state and handed to a device for processing.
• VirtioDeviceId / DeviceStatus: device-type IDs and transport status flags.
• GuestMemWriter: GPA-keyed accessor over guest RAM.
• Result / VirtioError: error types shared by all devices.
