Struct XhciTransferManager

pub struct XhciTransferManager {
    transfers: Arc<Mutex<VecDeque<Weak<Mutex<XhciTransferState>>>>>,
    device_slot: Weak<DeviceSlot>,
    stop_callback: Arc<Mutex<Vec<RingBufferStopCallback>>>,
}

Xhci Transfer manager holds reference to all ongoing transfers. Can cancel them all if needed.

Fields

transfers: Arc<Mutex<VecDeque<Weak<Mutex<XhciTransferState>>>>>

device_slot: Weak<DeviceSlot>

stop_callback: Arc<Mutex<Vec<RingBufferStopCallback>>>

Implementations

impl XhciTransferManager

pub fn new(device_slot: Weak<DeviceSlot>) -> XhciTransferManager

Create a new manager.

pub fn create_transfer( &self, mem: GuestMemory, port: Arc<UsbPort>, interrupter: Arc<Mutex<Interrupter>>, slot_id: u8, endpoint_id: u8, transfer_descriptor: TransferDescriptor, trigger_event: Event, stream_id: Option<u16>, ) -> XhciTransfer

Build a new XhciTransfer. Endpoint id is the id in xHCI device slot.

pub fn cancel_all(&self, callback: RingBufferStopCallback)

Cancel all current transfers and execute the callback once completed.

fn remove_transfer(&self, t: &Arc<Mutex<XhciTransferState>>)
