Crate arcbox_virtio 

arcbox-virtio

VirtIO device implementations for ArcBox.

This crate provides VirtIO device emulation including:

• blk: Block device (virtio-blk)
• net: Network device (virtio-net)
• console: Console device (virtio-console)
• fs: Filesystem device (virtio-fs)
• vsock: Socket device (virtio-vsock)

VirtIO Queue

All devices use the standard VirtIO queue (virtqueue) mechanism for communication with the guest. The queue module provides the core queue implementation.

Modules

balloon

Back-compat re-export of arcbox-virtio-balloon.

blk

Back-compat re-export of arcbox-virtio-blk.

console

Back-compat re-export of arcbox-virtio-console.

error

Error types for VirtIO devices.

fs

Back-compat re-export of arcbox-virtio-fs.

guest_mem

Guest memory accessor for direct virtqueue manipulation.

net

Back-compat re-export of arcbox-virtio-net.

queue

VirtIO queue (virtqueue) implementation.

queue_guest

VirtQueue operations over guest physical memory.

rng

Back-compat re-export of arcbox-virtio-rng.

vsock

Back-compat re-export of arcbox-virtio-vsock.

vsock_manager

Back-compat re-export of the vsock connection manager. The actual RxOps / VsockConnectionManager / VsockConnection definitions live in arcbox-virtio-vsock::manager after the per-device split.

Structs

AvailRing

Available ring structure.

Descriptor

A single descriptor in the descriptor table.

DeviceCtx

Per-device context shared between the VMM and each VirtioDevice for accessing guest physical memory and injecting interrupts.

DeviceStatus

VirtIO device status flags.

GuestMemWriter

Raw pointer wrapper for guest physical memory access.

QueueConfig

Configuration for a single virtqueue, as set by the guest driver via MMIO transport writes.

UsedRing

Used ring structure.

VirtQueue

VirtIO queue implementation.

Enums

VirtioDeviceId

VirtIO device type IDs.

VirtioError

Errors that can occur during VirtIO operations.

Traits

VirtioDevice

Trait for VirtIO devices.

Type Aliases

Result

Result type alias for VirtIO operations.
