Struct floppy::FloppyDiskController

pub struct FloppyDiskController { /* private fields */ }

82077AA Floppy disk controller

Implementations

impl FloppyDiskController

pub fn new( guest_memory: GuestMemory, interrupt: LineInterrupt, register_pio: &mut dyn RegisterPortIoIntercept, pio_base_addr: u16, disk_drive: DriveRibbon, dma: Box<dyn IsaDmaChannel>, ) -> Result<Self, NewFloppyDiskControllerError>

Create a new floppy disk controller.

pub fn offset_of(&self, addr: u16) -> Option<u16>

Return the offset of addr from the region’s base address.

Returns None if the provided addr is outside of the memory region, or the region is currently unmapped.

Trait Implementations

impl ChangeDeviceState for FloppyDiskController

fn start(&mut self)

Starts a device, allowing it to interact with the guest asynchronously.

async fn stop(&mut self)

Stops a device’s asynchronous work.

async fn reset(&mut self)

Resets the device state to its initial state, for a fresh boot.

impl ChipsetDevice for FloppyDiskController

fn supports_pio(&mut self) -> Option<&mut dyn PortIoIntercept>

Optionally returns a trait object to send IO port intercepts to.

fn supports_poll_device(&mut self) -> Option<&mut dyn PollDevice>

Optionally returns a trait object to send poll requests to.

fn supports_mmio(&mut self) -> Option<&mut (dyn MmioIntercept + 'static)>

Optionally returns a trait object to send MMIO port intercepts to.

fn supports_pci(&mut self) -> Option<&mut (dyn PciConfigSpace + 'static)>

Optionally returns a trait object to send PCI config space accesses to.

fn supports_line_interrupt_target( &mut self, ) -> Option<&mut dyn LineInterruptTarget>

Optionally returns a trait object to send interrupt line changes to.

fn supports_handle_eoi(&mut self) -> Option<&mut dyn HandleEoi>

Optionally returns a trait object to send EOI requests to.

fn supports_acknowledge_pic_interrupt( &mut self, ) -> Option<&mut dyn AcknowledgePicInterrupt>

Optionally returns a trait object with which to acknowledge PIC interrupts.

impl InspectMut for FloppyDiskController

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

Inspects the object.

impl PollDevice for FloppyDiskController

fn poll_device(&mut self, cx: &mut Context<'_>)

Poll the device for asynchronous work.

impl PortIoIntercept for FloppyDiskController

fn io_read(&mut self, io_port: u16, data: &mut [u8]) -> IoResult

Dispatch an IO port read to the device with the given address.

fn io_write(&mut self, io_port: u16, data: &[u8]) -> IoResult

Dispatch an IO port write to the device with the given address.

fn get_static_regions(&mut self) -> &[(&str, RangeInclusive<u16>)]

Report a set of static io port regions (region_name, port_range) that cannot be remapped at runtime and are always registered.

impl SaveRestore for FloppyDiskController

type SavedState = SavedState

The concrete saved state type.

fn save(&mut self) -> Result<Self::SavedState, SaveError>

Saves the object’s state.

fn restore(&mut self, state: Self::SavedState) -> Result<(), RestoreError>

Restores the object’s state.
