Struct EmulatedDevice

pub struct EmulatedDevice<T, U> { /* private fields */ }

A wrapper around any user_driver device T. It provides device emulation by providing access to the memory shared with the device and thus allowing the user to control device behaviour to a certain extent. Can be used with devices such as the NvmeController

Implementations

impl<T: PciConfigSpace + MmioIntercept, U: DmaClient> EmulatedDevice<T, U>

pub fn new(device: T, msi_set: MsiInterruptSet, dma_client: Arc<U>) -> Self

Creates a new emulated device, wrapping device of type T, using the provided MSI Interrupt Set. Dma_client should point to memory shared with the device.

Trait Implementations

impl<T: 'static + Send + InspectMut + MmioIntercept, U: 'static + Send + DmaClient> DeviceBacking for EmulatedDevice<T, U>

type Registers = Mapping<T>

An object for accessing device registers.

fn id(&self) -> &str

Returns a device ID for diagnostics.

fn map_bar(&mut self, n: u8) -> Result<Self::Registers>

Maps a BAR.

fn dma_client(&self) -> Arc<dyn DmaClient>

DMA Client for the device.

fn max_interrupt_count(&self) -> u32

Returns the maximum number of interrupts that can be mapped.

fn map_interrupt(&mut self, msix: u32, _cpu: u32) -> Result<DeviceInterrupt>

Maps a MSI-X interrupt for use, returning an object that can be used to wait for the interrupt to be signaled by the device.

impl<T: InspectMut, U> Inspect for EmulatedDevice<T, U>

fn inspect(&self, req: Request<'_>)

Inspects the object.
