Implementations

impl Frontend

fn new(virtio_gpu: VirtioGpu, fence_state: Arc<Mutex<FenceState>>) -> Frontend

pub fn display(&mut self) -> &Rc<RefCell<GpuDisplay>>

Returns the internal connection to the compositor and its associated state.

pub fn process_display(&mut self) -> ProcessDisplayResult

Processes the internal display events and returns true if any display was closed.

pub fn process_resource_bridge(&mut self, resource_bridge: &Tube) -> Result<()>

Processes incoming requests on resource_bridge.

pub fn process_gpu_control_command( &mut self, cmd: GpuControlCommand ) -> GpuControlResult

Processes the GPU control command and returns the result with a bool indicating if the GPU device’s config needs to be updated.

fn process_gpu_command( &mut self, mem: &GuestMemory, cmd: GpuCommand, reader: &mut Reader ) -> Result<GpuResponse, GpuResponse>

pub fn process_queue( &mut self, mem: &GuestMemory, queue: &dyn QueueReader ) -> bool

Processes virtio messages on queue.

fn process_descriptor( &mut self, mem: &GuestMemory, desc_chain: DescriptorChain ) -> Option<ReturnDescriptor>
