Struct FramebufferDevice

pub struct FramebufferDevice { /* private fields */ }

A chipset device for the framebuffer.

Implementations

impl FramebufferDevice

pub fn new( mapper: Box<dyn MemoryMapper>, framebuffer: Framebuffer, framebuffer_gpa_base_fixed: Option<u64>, ) -> Result<Self>

Creates a new framebuffer device from the specified framebuffer using the given mapper. Optionally creates a second mapping that does not move once the VM is started. This can be used fo VTL2 to read from.

pub fn into_framebuffer(self) -> Framebuffer

Gets the inner framebuffer back.

pub fn control(&self) -> FramebufferLocalControl

Gets the control plane for the framebuffer.

Trait Implementations

impl ChangeDeviceState for FramebufferDevice

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 FramebufferDevice

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

Optionally returns a trait object to send IO port intercepts 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_poll_device(&mut self) -> Option<&mut dyn PollDevice>

Optionally returns a trait object to send poll requests 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 FramebufferDevice

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

Inspects the object.

impl SaveRestore for FramebufferDevice

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.
