Struct VirtioDevice 

pub struct VirtioDevice {
    pub pci_dev: PciDevice,
    pub io_base: u16,
}

VirtIO device base

Common functionality for all VirtIO devices

Fields

pci_dev: PciDevice

PCI device

io_base: u16

I/O base address (BAR0 for legacy devices)

Implementations

impl VirtioDevice

pub unsafe fn new(pci_dev: PciDevice) -> Result<Self, &'static str>

Create a new VirtIO device from a PCI device

Safety

The PCI device must be a valid VirtIO device
