Trait for device models that handle I/O and MMIO

Required Methods

fn handle_io( &mut self, port: u16, is_write: bool, data: &mut [u8], ) -> Result<(), VmError>

Handle an I/O port access

fn handle_mmio( &mut self, addr: u64, is_write: bool, data: &mut [u8], ) -> Result<(), VmError>

Handle an MMIO access

fn get_state(&self) -> DeviceState

Get the serialized device state for migration

fn set_state(&mut self, state: &DeviceState) -> Result<(), VmError>

Restore device state from migration data
